Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

The display panel generally includes a plurality of pixels arranged in an array, and when the display panel displays a picture, gray scale data is provided to the display panel, where the gray scale data includes a plurality of display signals corresponding to the plurality of pixels of the display panel one to one, so that when the display panel displays the picture, the display signals in the gray scale data of the corresponding display picture are provided to the pixels one to one, so that the pixels emit light with corresponding brightness and color according to the received display signals, and the light emitted by the pixels is mixed to present the corresponding display picture.

In the prior art, the display signals of the pixels in the display panel are usually refreshed at a certain refresh frequency, so that the pixels can continuously display the corresponding display image. However, when the display signals of the pixels in the display panel are refreshed at a certain refresh frequency, all the pixels in the display panel are updated once every refresh, and all the pixels in the display panel are controlled to perform display. Therefore, the display panel has higher power consumption, and especially for a display device (such as a wearable device) with a single display screen, such continuous updating of all pixels can cause the display panel to have higher power consumption, which cannot meet the requirement of people on the low-power wearable device.

In order to solve the above technical problem, an embodiment of the present invention provides a display control method for a display panel, where the display control method for the display panel can control a display state of the display panel, the display control method for the display panel can be executed by the display control apparatus for the display panel provided in the embodiment of the present invention, the display control apparatus for the display panel can be composed of hardware and/or software, and the display control apparatus for the display panel can be integrated into a driving chip for driving the display panel to perform display in a display device. Fig. 1 is a flowchart of a display control method of a display panel according to an embodiment of the present invention. As shown in fig. 1, the display control method of the display panel includes:

s110, when the gray scale data of the (i + 1) th frame display picture is to be displayed, judging whether the gray scale data of the (i + 1) th frame display picture is the same as the gray scale data of the ith frame display picture; if yes, go to S120.

And S120, when the display picture of the (i + 1) th frame is displayed, controlling a first pixel in the adjacent first pixel and a first pixel in the adjacent second pixel with the same display signal to display according to the gray scale data of the display picture of the (i + 1) th frame, and controlling the first pixel and the adjacent second pixel with different display signals to display.

Fig. 2 is a schematic structural diagram of a display panel according to an embodiment of the present invention. As shown in fig. 2, the display panel 100 includes a plurality of pixels 10 arranged in an array, the plurality of pixels 10 includes first pixels 11 and second pixels 12, and the first pixels 11 and the second pixels 12 are alternately arranged at least along the first direction X. When the display panel 100 displays a picture, gray scale data of each frame of display picture is sequentially provided to the display panel, and the gray scale data of each frame of display picture comprises a plurality of display signals corresponding to the plurality of pixels 10 in the display panel 100 one by one, so that each pixel 10 in the display panel 100 can perform display light emission according to the received display signal. Because the light-emitting ranges of the adjacent pixels are overlapped, when a pure-color picture is displayed, even if one of the two adjacent pixels is controlled to display and emit light, the picture display requirement can be met. Each pixel 10 of the display panel 100 may include a plurality of sub-pixels (not shown) with different colors, so that the display panel 100 can present a display with rich and diversified colors instead of displaying a pure color display.

Specifically, the first pixels 11 and the second pixels 12 are alternately arranged only in the first direction X as an example. When the display panel 100 displays the display screen of the ith frame, the gray scale data of the display screen of the ith frame is provided to the display panel 100, and when the display panel is to display the display screen of the (i + 1) th frame, the gray scale data of the display screen of the (i + 1) th frame needs to be provided to the display panel 100. Comparing whether the gray scale data of the ith frame display picture is the same as the gray scale data of the (i + 1) th frame display picture; if the gray scale data of the display frame of the ith frame is the same as the gray scale data displayed by the frame i +1, the display frame of the ith frame displayed by the display panel 100 is the same as the display frame of the frame i +1 displayed by the display panel; at this time, whether the display signals of the adjacent first pixel 11 and second pixel 12 are the same or not may be compared according to the display signals of the pixels in the gray scale data of the display screen of the (i + 1) th frame, and when the display screen of the (i + 1) th frame is displayed, the first pixel 11 of the adjacent first pixel 11 and the second pixel 12 which have the same display signal performs display light emission according to the display signals, the second pixel 12 does not emit light, and the first pixel 11 and the second pixel 12 which have different adjacent display signals perform display light emission according to the respective display signals.

When each pixel comprises a plurality of sub-pixels with different colors, the display signals of the adjacent first pixel 11 and second pixel 12 are the same, specifically, the data signals of the sub-pixels with the same color in the first pixel 11 and the second pixel 12 are the same, so that the sub-pixels with the same color in the first pixel 11 and the second pixel 12 have the same display light emitting brightness. Illustratively, taking as an example that each pixel includes a red sub-pixel, a green sub-pixel and a blue sub-pixel, when the display signals of the first pixel 11 and the second pixel 12 are the same, the data signal of the red sub-pixel in the first pixel 11 is the same as the data signal of the red sub-pixel in the second pixel 12, the data signal of the green sub-pixel in the first pixel 11 is the same as the data signal of the green sub-pixel in the second pixel 12, and the data signal of the blue sub-pixel in the first pixel 11 is the same as the data signal of the blue sub-pixel in the second pixel 12, so that the display light emission color and the luminance exhibited by the first pixel 11 and the second pixel 12 are the same.

For example, fig. 3 is a schematic diagram of a display screen provided by an embodiment of the present invention; fig. 4 is a schematic diagram of an i +1 th frame display screen according to an embodiment of the present invention. As shown in fig. 3, when the display frame of the ith frame and the display frame of the (i + 1) th frame are both display frames presenting the number "21" with a preset color and brightness in a white background, the display signals of the adjacent first pixel 111 and second pixel 112, the display signals of the adjacent first pixel 113 and second pixel 114, the display signals of the adjacent first pixel 121 and second pixel 122, and the display signals of the adjacent first pixel 123 and second pixel 124 are compared, respectively. At this time, as shown in fig. 4, the display signals of the adjacent first pixel 111 and second pixel 112 are the same, and when displaying the display screen of the (i + 1) th frame, the first pixel 111 is controlled to display and emit light, and the second pixel 112 is controlled not to emit light; the display signals of the adjacent first pixel 113 and second pixel 114 are the same, and when displaying the display picture of the (i + 1) th frame, the first pixel 113 is controlled to display and emit light, and the second pixel 114 is controlled not to emit light; the display signals of the adjacent first pixel 121 and second pixel 122 are the same, and when displaying the display screen of the (i + 1) th frame, the first pixel 121 is controlled to display and emit light, and the second pixel 122 is controlled not to emit light; the display signals of the adjacent first pixel 123 and second pixel 124 are different, and when the display screen of the (i + 1) th frame is displayed, the first pixel 123 and second pixel 124 are controlled to emit display light.

It can be understood that, the above description only takes 111, 112, 113, 114, 121, 122, 123, and 124 as an example, and an exemplary description is given to a display control manner of the display screen of the (i + 1) th frame, and a person skilled in the art can know display control conditions of other pixels in the display panel according to the above exemplary example, and details are not repeated here. For convenience of description, the following exemplarily illustrates a display control situation of several pixels in a display panel, and the technical solution of the embodiment of the present invention is exemplarily described.

S130, when the gray scale data of the (i + 2) th frame display picture is to be displayed, judging whether the gray scale data of the (i + 2) th frame display picture is the same as the gray scale data of the (i + 1) th frame display picture; if yes, go to S140.

S140, when the display picture of the (i + 2) th frame is displayed, according to the gray scale data of the display picture of the (i + 2) th frame, controlling the adjacent first pixel and the second pixel with the same display signal to display, and controlling the adjacent first pixel and the adjacent second pixel with different display signals to display.

Specifically, with reference to fig. 2, when the display screen of the (i + 2) th frame is to be displayed, comparing whether the gray scale data of the display screen of the (i + 1) th frame is the same as the gray scale data of the display screen of the (i + 2) th frame; if the gray scale data of the display frame of the (i + 1) th frame is the same as the gray scale data displayed by the (i + 2) th frame, the display frame of the (i + 1) th frame displayed by the display panel 100 is the same as the display frame of the (i + 2) th frame displayed by the display panel; at this time, whether the display signals of the adjacent first pixel 11 and second pixel 12 are the same or not may be compared according to the display signals of the pixels in the gray scale data of the display screen of the (i + 2) th frame, and when the display screen of the (i + 2) th frame is displayed, the second pixel 12 of the adjacent first pixel 11 and second pixel 12 with the same display signal is controlled to perform display light emission according to the display signal, the first pixel 11 does not emit light, and the first pixel 11 and second pixel 12 with different adjacent display signals are controlled to perform display light emission according to the respective display signals.

Exemplarily, fig. 5 is a schematic diagram of an i +2 th frame display screen provided in an embodiment of the present invention. As shown in fig. 3 and 5, the display frames of the i +2 th frame are the same as the display frames of the i +1 th frame, and are both display frames presenting a number "21" in a white background with a preset color and brightness; when a display picture of an i +2 th frame is displayed, a second pixel 112 in a first pixel 111 and a second pixel 112 which are adjacent to each other and have the same display signal is controlled to display luminescence and a first pixel 111 does not emit luminescence, a second pixel 114 in a first pixel 113 and a second pixel 114 which are adjacent to each other and have the same display signal is controlled to display luminescence and a first pixel 113 does not emit luminescence, a second pixel 122 in a first pixel 121 and a second pixel 122 which are adjacent to each other and have the same display signal is controlled to display luminescence and a first pixel 121 does not emit luminescence, and a first pixel 123 and a second pixel 124 which are adjacent to each other and have different display signals are controlled to display luminescence.

In this way, when the gray scale data of the ith frame display picture is the same as that of the (i + 1) th frame display picture, the first pixels of the two adjacent pixels with the same display signals in the (i + 1) th frame display picture are controlled to display and emit light, and when the gray scale data of the (i + 1) th frame display picture is the same as that of the (i + 2) th frame display picture, the second pixels of the two adjacent pixels with the same display signals in the (i + 2) th frame display picture are controlled to display and emit light, compared with the case that all the pixels are controlled to display and emit light in each frame display picture, the number of the pixels displaying and emitting light in the (i + 1) th frame display picture and the (i + 2) th frame display picture can be reduced, so that the power consumption of the display panel can be reduced; meanwhile, two adjacent pixels with the same display signals respectively perform display luminescence in the (i + 1) th frame display picture and the (i + 2) th frame display picture, so that the two adjacent pixels with the same display signals perform alternate display, the display luminescence life and the attenuation degree of all the pixels in the display panel can be ensured to be consistent, and the display uniformity of the display panel can be improved; in addition, when the display panel displays the (i + 1) th frame display picture and the (i + 2) th frame display picture, besides controlling one of two adjacent pixels with the same display signal to display and emit light, the display panel also controls two adjacent pixels with different display signals to display and emit light, so that the integrity of the displayed display picture can be ensured, and the phenomenon that part of color and/or brightness in the display picture is lost due to the control of one of the two adjacent pixels with different display signals to display, so that the distortion of the display picture of the current frame is caused, and the display effect of the display panel can be improved.

It should be noted that fig. 2 to 4 are merely exemplary drawings of the embodiment of the present invention, and fig. 2 to 4 only exemplarily show that the first direction is a row direction X of the pixels, and the first pixels 11 and the second pixels 12 are only alternately arranged along the row direction X; in the embodiment of the present invention, the first direction may also be a column direction of the pixels, and in this case, the first pixels and the second pixels may also be alternately arranged along the column direction.

Illustratively, the first pixels 11 and the second pixels 12 are alternately arranged in the column direction Y.

Compared with the case that all pixels are controlled to display and emit light in each frame of display picture, the number of pixels displaying and emitting light in the (i + 1) th frame of display picture and the (i + 2) th frame of display picture can be reduced, so that the power consumption of the display panel is reduced, the display uniformity of the display panel is ensured, and the display effect of the display panel is improved.

In addition, in the embodiment of the present invention, the first pixels and the second pixels may be alternately arranged in both the first direction and the second direction. The first direction may be a row direction of the pixels, and the second direction may be a column direction of the pixels; or the first direction is the row direction of the pixels and the second direction is the column direction of the pixels.

Illustratively, the first pixels 11 and the second pixels 12 are alternately arranged in both the row direction X and the column direction Y. As shown in fig. 8, if the gray-scale data of the display frame of the ith frame is the same as the gray-scale data of the display frame of the (i + 1) th frame, when the display frame of the (i + 1) th frame is displayed, the display signals are controlled to be the same, the first pixel 111 of the adjacent first pixel 111 and the second pixel 112 displays light and the second pixel 112 does not emit light, the display signals are controlled to be the same, the first pixel 113 of the adjacent first pixel 113 and the adjacent second pixel 114 displays light and the second pixel 114 does not emit light, the display signals are controlled to be the same, the first pixel 122 of the adjacent first pixel 122 and the adjacent second pixel 121 displays light and the second pixel 121 does not emit light, and the display signals are controlled to be different, and the adjacent first pixel 124 and the adjacent second pixel 123 both display light.

Optionally, when two adjacent pixels in the same row of pixels are a pixel group, or two adjacent pixels in the same column of pixels are a pixel group, the display condition of the two pixels in the same pixel group can be determined by comparing the display signals of the two pixels in the same pixel group.

And S1212, when displaying the display screen of the (i + 1) th frame, providing the display signal of the first alternate pixel in the display screen of the (i + 1) th frame to the first alternate pixel, providing the display signal corresponding to the 0 gray-scale value to the second alternate pixel, and providing the display signal of the non-alternate pixel in the display screen of the (i + 1) th frame to the non-alternate pixel.

Illustratively, the first pixels and the second pixels are alternately arranged only in the row direction. As shown in fig. 3, when the display frame of the ith frame is the same as the display frame of the (i + 1) th frame, based on the gray scale data of the display frame of the (i + 1) th frame, the adjacent first pixel 111 and second pixel 112 belong to the same pixel group 101 and the display signals are the same (for example, the gray scale values corresponding to the data signals of the sub-pixels in the first pixel 111 and the second pixel 112 are both 255), the first pixel 111 can be determined as a first alternate pixel, and the second pixel 112 can be determined as a second alternate pixel; the adjacent first pixel 123 and second pixel 124 belong to the same pixel group 101 and display signals are different, and both the first pixel 123 and second pixel 124 may be determined as non-alternating pixels.

As shown in fig. 4, when displaying the display screen of the (i + 1) th frame, the display signal of the first alternate pixel 111 in the display screen of the (i + 1) th frame may be provided to the first alternate pixel 111, for example, a data signal corresponding to a gray level of 255 is provided to each sub-pixel in the first alternate pixel 111, so that each sub-pixel in the first alternate pixel 111 has the brightest light emission luminance, and a display signal corresponding to a gray level of 0 is provided to the second alternate pixel 112, that is, a data signal corresponding to a gray level of 0 is provided to each sub-pixel in the second alternate pixel 112, so that each sub-pixel in the second alternate pixel 112 has the darkest light emission luminance; meanwhile,

non-alternating pixels

123 and 124 are each provided with their respective display signals such that alternating pixel 123 is capable of displaying light of a respective brightness and color in accordance with its display signal, and alternating pixel 124 is capable of displaying light of a respective brightness and color in accordance with its display signal.

In general, the luminance of each sub-pixel in each pixel of the display panel 100 is proportional to the power consumption of the sub-pixel, i.e. the higher the luminance of the sub-pixel is, the higher the power consumption of the sub-pixel is, therefore, when the luminance of the sub-pixel is the luminance corresponding to the 0 gray-scale value, the sub-pixel has the least power consumption compared to the luminance corresponding to other gray-scale values. In this way, compared with the case that the first alternating pixels and the second alternating pixels in the same pixel group are provided with the display signals corresponding to the first alternating pixels respectively, when the display signals corresponding to the first alternating pixels are provided only for the first alternating pixels in the same pixel group, and the display signals corresponding to the 0 gray-scale value are provided for the second alternating pixels, the power consumption of the display panel can be reduced; meanwhile, the data signals corresponding to the non-alternating pixels are provided for the non-alternating pixels, so that the display panel can have a good display effect.

Fig. 11 is a flowchart of a display control method for an i +2 th frame display screen according to an embodiment of the present invention. As shown in fig. 11, the display control method of the display screen of the (i + 2) th frame includes:

And S1412, when the display picture of the (i + 2) th frame is displayed, providing the display signal of the second alternate pixel in the display picture of the (i + 2) th frame to the second alternate pixel, providing the display signal corresponding to the 0 gray-scale value to the first alternate pixel, and providing the display signal of the non-alternate pixel in the display picture of the (i + 2) th frame to the non-alternate pixel.

For example, also taking the example that the first pixels and the second pixels are alternately arranged only along the row direction as an example, when the display frame of the (i + 1) th frame is the same as the display frame of the (i + 2) th frame, the manner of determining the first alternate pixels, the second alternate pixels and the non-alternate pixels according to the gray scale data of the display frame of the (i + 2) th frame is the same as the manner of determining the first alternate pixels, the second alternate pixels and the non-alternate pixels according to the gray scale data of the display frame of the (i + 1) th frame, and the same points can refer to the description of determining the first alternate pixels, the second alternate pixels and the non-alternate pixels according to the gray scale data of the display frame of the (i + 1) th frame, and will not be described herein again.

As shown in fig. 5, when displaying the display screen of the (i + 2) th frame, the display signal of the second alternate pixel 112 in the display screen of the (i + 2) th frame may be provided to the second alternate pixel 112, for example, a data signal corresponding to a gray level of 255 is provided to each sub-pixel in the second alternate pixel 112, so that each sub-pixel in the second alternate pixel 112 has the brightest light-emitting luminance, and a display signal corresponding to a gray level of 0 is provided to the first alternate pixel 111, that is, a data signal corresponding to a gray level of 0 is provided to each sub-pixel in the first alternate pixel 111, so that each sub-pixel in the first alternate pixel 111 has the darkest light-emitting luminance; meanwhile,

non-alternating pixels

In this way, compared with the case that the first alternating pixels and the second alternating pixels in the same pixel group are provided with the display signals corresponding to the first alternating pixels and the second alternating pixels, when the display signals corresponding to the second alternating pixels are provided only to the second alternating pixels in the same pixel group, and the display signals corresponding to the 0 gray-scale value are provided to the first alternating pixels, the power consumption of the display panel can be reduced; meanwhile, data signals corresponding to the non-alternating pixels are provided for the non-alternating pixels, so that the display panel can be ensured to have a good display effect; in addition, when the display pictures of the three continuous frames are the same, the first alternating pixels and the second alternating pixels are controlled to be alternately displayed in at least two subsequent frames of display pictures, so that the display consistency of the display panel can be ensured.

Optionally, when the first pixels and the second pixels are alternately arranged in the first direction and the second direction, in each pixel in the odd-numbered rows, every two adjacent pixels form a first pixel group, and in each pixel in the same column, every two adjacent pixels form a second pixel group; or, in each pixel in the even-numbered rows, every two adjacent pixels form a first pixel group, and in each pixel in the same column, every two adjacent pixels form a second pixel group; or, in each pixel located in the odd-numbered columns, every two adjacent pixels form a first pixel group, and in each pixel located in the same row, every two adjacent pixels form a second pixel group; or, in each pixel in the even-numbered columns, every two adjacent pixels form a first pixel group, and in each pixel in the same row, every two adjacent pixels form a second pixel group. In this way, when comparing the display signals of two adjacent pixels, the display signals of two pixels in the first pixel group can be compared first, and then the display signals of two pixels in the second pixel group can be compared.

Illustratively, fig. 13 is a schematic diagram of a display control process of an i +1 th frame display screen corresponding to fig. 12. As shown in fig. 13, taking as an example that each adjacent two pixels among the pixels in the odd-numbered rows constitute a first pixel group 101, and each adjacent two pixels among the pixels in the same column constitute a second pixel group 102, for example, the first pixel 111 and the second pixel 112 constitute a first pixel group, the first pixel 113 and the second pixel 114 constitute a first pixel group, the first pixel 111 and the second pixel 121 constitute a second pixel group, the second pixel 112 and the first pixel 122 constitute a second pixel group, the first pixel 113 and the second pixel 123 constitute a second pixel group, and the second pixel 114 and the first pixel 124 constitute a second pixel group.

If the gray-scale data of the ith frame of display screen is the same as the gray-scale data of the (i + 1) th frame of display screen, and the display panel 100 displays the screen H11 according to the gray-scale data of the (i + 1) th frame of display screen, the display signals of two pixels belonging to the same first pixel group, for example, the display signals of the first pixel 111 and the second pixel 112 belonging to the same first pixel group, and the display signals of the first pixel 113 and the second pixel 114 belonging to the same first pixel group, can be compared according to the gray-scale data of the (i + 1) th frame of display screen; since the display signals of the first pixel 111 and the second pixel 112 belonging to the same first pixel group are the same, and the display signals of the first pixel 113 and the second pixel 114 belonging to the same first pixel group are the same, the display signals of the second pixel 112 and the second pixel 114 can be modified into the display signal corresponding to the gray-scale value of 0, and the gray-scale data of the display picture of the (i + 1) th frame after modification can be obtained; when the modified gray-scale data of the display frame of the i +1 th frame is used for displaying, the display panel 100 displays a frame H12 for each pixel. Then, according to the modified gray-scale data of the display frame of the (i + 1) th frame, comparing the display signals of two pixels belonging to the same second pixel group, for example, comparing the display signals of the first pixel 111 and the second pixel 121 belonging to the same second pixel group, comparing the display signals of the second pixel 112 and the first pixel 122 belonging to the same second pixel group, comparing the display signals of the first pixel 113 and the second pixel 123 belonging to the same second pixel group, and comparing the display signals of the first pixel 114 and the second pixel 124 belonging to the same second pixel group; since the display signals of the first pixel 111 and the second pixel 121 belonging to the same second pixel group are the same and the display signals of the first pixel 113 and the second pixel 123 belonging to the same second pixel group are the same, both the display signal of the second pixel 121 and the display signal of the second pixel 123 can be modified into the display signal corresponding to the 0 gray scale, and the gray scale data of the display picture of the corrected (i + 1) th frame can be obtained. When displaying the display screen of the (i + 1) th frame, a display signal is provided to each pixel of the display panel 100 according to the corrected gray-scale data of the display screen of the (i + 1) th frame, so that each pixel in the display panel presents the screen H13. Therefore, on the premise of reducing the power consumption of the display panel, the display uniformity of the display panel can be further improved, and the display effect of the display panel is further improved.

S1422, comparing the display signals of the two pixels in the second pixel group according to the modified gray scale data of the display picture of the (i + 2) th frame, and modifying the display signal corresponding to the first pixel in the two pixels which belong to the same second pixel group and have the same display signal in the modified gray scale data of the display picture of the (i + 2) th frame into the display signal corresponding to the gray scale value of 0 to obtain the corrected gray scale data of the display picture of the (i + 2) th frame;

s1423, when displaying the (i + 2) th frame display screen, providing a display signal to each pixel in a one-to-one correspondence manner according to the corrected gray scale data of the (i + 2) th frame display screen.

Fig. 15 is a schematic diagram illustrating an exemplary display control process of an i +2 th frame display screen corresponding to fig. 14. As shown in fig. 15, it is also taken as an example that every two adjacent pixels among the pixels located in the odd-numbered rows constitute a first pixel group 101, and every two adjacent pixels among the pixels located in the same column constitute a second pixel group 102. When the gray scale data of the display picture of the (i + 1) th frame is the same as the gray scale data of the display picture of the (i + 2) th frame, and the display is performed according to the gray scale data of the display picture of the (i + 2) th frame, the display panel 100 displays a picture H21, that is, when the display is the same as the picture displayed according to the gray scale data of the display picture of the (i + 1) th frame, the display signals of the first pixel 111 and the first pixel 113 can be modified into display signals corresponding to a gray scale value of 0 according to the gray scale data of the display picture of the (i + 2) th frame, and the modified gray scale data of the display picture of the (i + 1) th frame can be obtained; when the modified gray-scale data of the display frame of the i +1 th frame is used for displaying, the display panel 100 displays a frame H22 for each pixel. Then, according to the modified gray scale data of the display picture of the (i + 1) th frame, the display signals of the two pixels belonging to the same second pixel group are compared, and it can be known that the display signals of the second pixel 112 and the first pixel 121 of the same second pixel group are the same, so that the display signal of the first pixel 121 can be modified into the display signal corresponding to the gray scale of 0, and the gray scale data of the modified display picture of the (i + 2) th frame can be obtained. When displaying the display screen of the (i + 2) th frame, a display signal is provided to each pixel of the display panel 100 according to the corrected gray-scale data of the display screen of the (i + 2) th frame, so that each pixel in the display panel presents the screen H23. Therefore, on the premise of reducing the power consumption of the display panel, the display uniformity of the display panel can be further improved, and the display effect of the display panel can be further improved.

In the above exemplary description, the case that the gray scale data of the display frame i is the same as the gray scale data of the display frame i +1, and the gray scale data of the display frame i +1 is the same as the gray scale data of the display frame i +2 is described, but in the embodiment of the present invention, when the gray scale data of the display frame i is different from the gray scale data of the display frame i +1, and/or the gray scale data of the display frame i +1 is different from the gray scale data of the display frame i +2, each pixel in the display panel may be controlled to display as needed.

Optionally, fig. 16 is a flowchart of a display control method of a display panel according to another embodiment of the present invention. As shown in fig. 16, the display control method of the display panel includes:

s210, when the gray scale data of the (i + 1) th frame display picture is to be displayed, judging whether the gray scale data of the (i + 1) th frame display picture is the same as the gray scale data of the ith frame display picture; if yes, go to S120; if not, go to S230.

S220, when the display picture of the (i + 1) th frame is displayed, according to the gray scale data of the display picture of the (i + 1) th frame, controlling the first pixel in the adjacent first pixel and the second pixel with the same display signal to display, and controlling the first pixel and the second pixel with different display signals and adjacent to each other to display.

And S230, when the display picture of the (i + 1) th frame is displayed, providing display signals to the pixels in a one-to-one correspondence mode according to the gray scale data of the display picture of the (i + 1) th frame.

S240, when the gray scale data of the (i + 2) th frame display picture is to be displayed, judging whether the gray scale data of the (i + 2) th frame display picture is the same as the gray scale data of the (i + 1) th frame display picture; if yes, executing S250; if not, go to S260.

And S250, when the display picture of the (i + 2) th frame is displayed, controlling a first pixel and a second pixel which have the same display signal and are adjacent to each other to display according to the gray scale data of the display picture of the (i + 2) th frame, and controlling the first pixel and the second pixel which have different display signals and are adjacent to each other to display.

And S260, when the display picture of the (i + 2) th frame is displayed, providing display signals to the pixels in a one-to-one correspondence mode according to the gray scale data of the display picture of the (i + 2) th frame.

Therefore, when the gray scale data of the display picture of the ith frame is the same as the gray scale data of the display picture of the (i + 1) th frame and the gray scale data of the display picture of the (i + 1) th frame are the same, the first pixel and the second pixel which have the same display signals and are adjacent can be controlled to be alternately displayed in the display picture of the (i + 1) th frame and the display picture of the (i + 2) th frame respectively so as to reduce the power consumption of the display picture; if the gray scale data of the display picture of the ith frame is different from the gray scale data of the display picture of the (i + 1) th frame, when the display picture of the (i + 1) th frame is displayed, each pixel of the display panel can be controlled to display according to each display signal in the gray scale data of the (i + 1) th display picture, so that the display panel can display the complete picture of the (i + 1) th frame; and/or if the gray scale data of the (i + 1) th frame display picture is different from the gray scale data of the (i + 2) th frame display picture, when the (i + 2) th frame display picture is displayed, controlling each pixel of the display panel to display according to each display signal in the gray scale data of the (i + 2) th frame display picture, so that the display panel can display the complete picture of the (i + 2) th frame, and the display panel has a better display effect.

Optionally, when the gray scale data of the display picture of the (i + 1) th frame is the same as the gray scale data of the display picture of the (i) th frame, the refresh frequency of the display picture of the (i + 1) th frame switched from the display picture of the (i) th frame is a first refresh frequency; when the gray scale data of the display picture of the (i + 1) th frame is different from the gray scale data of the display picture of the (i) th frame, the refresh frequency of the display picture of the (i + 1) th frame is switched to be the second refresh frequency; and/or when the gray scale data of the display picture of the (i + 2) th frame is the same as the gray scale data of the display picture of the (i + 1) th frame, the refresh frequency of the display picture of the (i + 1) th frame is switched to be the first refresh frequency; when the gray scale data of the display picture of the (i + 2) th frame is different from the gray scale data of the display picture of the (i + 1) th frame, the refresh frequency of the display picture of the (i + 1) th frame is switched to be the second refresh frequency; wherein the second refresh frequency is greater than the first refresh frequency.

Because the power consumption of the display panel is positively correlated with the refresh frequency, the higher the refresh frequency is, the higher the power consumption of the display panel is; therefore, when the gray scale data of two adjacent frames of display frames are the same, the refreshing frequency of the display panel can be properly reduced, so as to reduce the power consumption of the display panel. Meanwhile, the higher the refresh frequency of the display panel is, the shorter the update time of the display frame of the display panel is, that is, when the gray scale data of the display frames of two adjacent frames are different, the refresh frequency of the display panel can be properly increased, so that the display panel can have better display quality.

When the second refresh frequency is greater than the first refresh frequency, the second refresh frequency may be an integer multiple of the first refresh frequency, that is, the second refresh frequency may be m times of the first refresh frequency, where m is a positive integer. For example, when the second refresh rate is 30Hz, the first refresh rate may be 15 Hz.

It should be noted that, the above description is only exemplary, and when the gray scale data of the current frame display picture to be displayed is different from the gray scale data of the previous frame display picture, all pixels in the display panel may be refreshed according to the gray scale data of the current frame display picture when the current frame display picture is displayed; in the embodiment of the present invention, when the gray scale data of the current frame display frame to be displayed is different from the gray scale data of the previous frame display frame, other display control modes may be adopted.

Optionally, if the gray-scale data of the (i + 1) th frame display picture is different from the gray-scale data of the ith frame display picture, determining an update pixel and a non-update pixel in each pixel according to the gray-scale data of the (i + 1) th frame display picture and the gray-scale data of the ith frame display picture; the updated pixel is a pixel with a display signal in the (i + 1) th frame display picture different from the display signal in the ith frame display picture; the non-update pixel is a pixel of which the display signal in the (i + 1) th display picture is the same as the display signal in the ith frame display picture; when the display picture of the (i + 1) th frame is displayed, according to the gray scale data of the display picture of the (i + 1) th frame, the first pixels of the adjacent first pixels and the second pixels with the same display signals in the non-updated pixels are controlled to display, the adjacent first pixels and the adjacent second pixels with different display signals in the non-updated pixels are controlled to display, and the updated pixels are controlled to display.

Illustratively, fig. 17 is a schematic diagram of another display screen provided by an embodiment of the present invention. Taking the example of the frame displayed according to the gray scale data in the ith frame as shown in FIG. 3, and the frame displayed according to the gray scale data in the (i + 1) th frame as shown in FIG. 17. Referring to fig. 3 and 17 in combination, the display screen of the i-th frame displays the number "21" in the white background, and the display screen of the i + 1-th frame displays the number "22" in the white background, that is, the display signals corresponding to the

pixels

121, 122, 123, 125, 131, 134, 141, 142, 143, 145, 154, 155, 161, 162, 163, and 165 in the gray-scale data of the display screen of the i + 1-th frame are changed compared to the gray-scale data of the display screen of the i-th frame, so that the

pixels

121, 122, 123, 125, 131, 134, 141, 142, 143, 145, 154, 155, 161, 162, 163, and 165 are update pixels, and the other pixels are non-update pixels.

Illustratively, fig. 18 is a schematic diagram of a display screen of an i +1 th frame according to an embodiment of the present invention. As shown in fig. 17 and 18, when the display screen of the (i + 1) th frame is displayed, the

pixels

121, 122, 123, 125, 131, 134, 141, 142, 143, 145, 154, 155, 161, 162, 163, and 165 may be controlled to display, and the first pixel of two pixels adjacent to each other and having the same display signal among the other non-update pixels may be controlled to display, and the pixels adjacent to each other and having different display signals among the other non-update pixels may be controlled to display.

In this embodiment, when the i frame display screen is different from the i +1 frame display screen in terms of partial gray scale data, the display signals can be provided to the update pixels in a one-to-one correspondence manner when the i +1 frame display screen is displayed, instead of the update pixels being maintained as the first pixels of two adjacent pixels with the same display signals for displaying, and the two adjacent pixels with different display signals for displaying; in this way, even if the i-th frame display screen and the (i + 1) -th frame display screen have different gray scale data, the number of pixels for displaying and emitting light can be reduced when the i-th frame display screen is displayed, so that the power consumption of the display panel is reduced, and the display effect of the display panel is improved.

Optionally, when the gray-scale data of the display picture of the (i + 1) th frame is different from the gray-scale data of the display picture of the (i) th frame, when the display picture of the (i) th frame is switched to the display picture of the (i + 1) th frame, the display signal is provided to each update pixel at the second refresh frequency, and the display signal is provided to each pixel for displaying in each non-update pixel at the first refresh frequency; wherein the second refresh frequency is greater than the first refresh frequency. At this time, when the display screen of the ith frame is switched to the display screen of the (i + 1) th frame, the time required for the update pixel to obtain the display signal corresponding to the update pixel is less than the time required for each pixel displayed in the non-update pixels to obtain the display signal corresponding to the update pixel, so that the content displayed by the update pixel can be displayed in time, and the display effect of the display panel can be improved; meanwhile, the higher the refresh frequency is, the higher the power consumption of the display panel is, so that when the display signal of the non-updated pixel is refreshed at a lower refresh frequency, the power consumption of the display panel can be further reduced.

Similarly, if the gray scale data of the display picture of the (i + 2) th frame is different from the gray scale data of the display picture of the (i + 1) th frame, determining an update pixel and a non-update pixel in each pixel according to the gray scale data of the display picture of the (i + 2) th frame and the gray scale data of the display picture of the (i + 1) th frame; the updated pixels are pixels with different display signals in the display picture of the (i + 2) th frame and the display signals in the display picture of the (i + 1) th frame; the non-update pixel is a pixel of which the display signal in the (i + 2) th display picture is the same as the display signal in the (i + 1) th frame display picture; when the display picture of the (i + 2) th frame is displayed, according to the gray scale data of the display picture of the (i + 2) th frame, controlling the first pixels and the second pixels which have the same display signals and are adjacent in each non-updated pixel to display, controlling the first pixels and the second pixels which have different display signals and are adjacent in each non-updated pixel to display, and controlling the updated pixels to display.

For example, fig. 19 is a schematic diagram of another display screen provided in the embodiment of the present invention, and fig. 20 is a schematic diagram of another display screen of the (i + 2) th frame provided in the embodiment of the present invention. Taking the example of FIG. 17 showing the frame displayed according to the gray scale data of the (i + 1) th frame and FIG. 19 showing the frame displayed according to the gray scale data of the (i + 2) th frame as an example. Referring to fig. 17, 19 and 20 in combination, the display frame of the (i + 1) th frame displays the number "22" in the white background, and the display frame of the (i + 2) th frame displays the number "23" in the white background, that is, compared with the gray-scale data of the display frame of the (i + 1) th frame, the display signals corresponding to the

pixels

151 and 155 in the gray-scale data of the display frame of the (i + 2) th frame are changed, so that the

pixels

151 and 155 are updated pixels, and the other pixels are non-updated pixels. When displaying the display screen of the (i + 2) th frame, the

pixels

151 and 155 are controlled to display, and the second pixel of two pixels adjacent to each other and having the same display signal among the other non-updated pixels is controlled to display, and the pixels adjacent to each other and having different display signals among the other non-updated pixels are controlled to display. In this way, the power consumption of the display screen can be reduced, and the display effect of the display panel can be improved.
