Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
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, wherein the gray-scale data includes a plurality of display signals corresponding to the plurality of pixels of the display panel one by 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 by one, so that each pixel emits light with corresponding brightness and color according to the display signals received by the pixel, and the light emitted by each pixel is mixed to present the corresponding display picture.
In the prior art, display signals of each pixel in a display panel are generally refreshed at a certain refresh frequency, so that each pixel can continuously display a corresponding display screen. 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 display. Therefore, the display panel has higher power consumption, and particularly for display equipment (such as wearing equipment) with single display picture, the continuous updating of all pixels can enable the display panel to have higher power consumption, so that the requirement of people on the wearing equipment with low power consumption cannot be met.
In order to solve the above-mentioned technical problems, an embodiment of the present invention provides a display control method of a display panel, which can control a display state of the display panel, the display control method of the display panel may be executed by the display control device of the display panel provided by the embodiment of the present invention, the display control device of the display panel may be composed of hardware and/or software, and the display control device of the display panel may be integrated in a driving chip for driving the display panel to display in a display device.

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 identical to the gray-scale data of the (i) -th frame display picture; if yes, then execution proceeds to S120.
S120, when the (i+1) th frame display picture is displayed, according to the gray scale data of the (i+1) th frame display picture, the first pixels in the first pixels and the second pixels which are the same in display signal and adjacent to each other are controlled to display, and the first pixels and the second pixels which are different in display signal and adjacent to each other are controlled 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 a first direction X. When the display panel 100 displays a picture, the 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 includes 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 and light emission according to the display signals received by the pixel. Since the light emitting ranges of the adjacent pixels overlap, when a pure-color picture is displayed, even if one of the adjacent two pixels is controlled to perform display light emission, the picture display requirement can be satisfied. Each pixel 10 of the display panel 100 may include a plurality of sub-pixels (not shown) of different colors, so that the display panel 100 is not only capable of displaying a pure color display screen, but also capable of presenting a color-rich and diversified display screen.
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 ith frame of display screen, the display panel 100 is provided with the gray-scale data of the ith frame of display screen, and when the display panel is to display the ith+1 frame of display screen, the display panel 100 is required to be provided with the gray-scale data of the ith+1 frame of display screen.

When each pixel includes 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. For example, taking an example in which 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 signals of the red sub-pixel and the red sub-pixel in the first pixel 11 and the data signals of the green sub-pixel and the green sub-pixel in the first pixel 11 and the data signals of the blue sub-pixel and the blue sub-pixel in the second pixel 12 are the same, respectively, the first pixel 11 and the second pixel 12 exhibit the same display emission color and brightness.

Therefore, compared with the situation that all pixels are controlled to display and emit light in each frame of display picture, the number of pixels for 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.
Further, 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.

As shown in fig. 8, if the gray-scale data of the i-th frame display is the same as the gray-scale data of the i+1th frame display, when the i+1th frame display is displayed, the first pixel 111 and the second pixel 112 which are adjacent to each other with the same display signal are controlled to emit light and the second pixel 112 does not emit light, the first pixel 113 and the second pixel 114 which are adjacent to each other with the same display signal are controlled to emit light, the first pixel 122 and the second pixel 121 which are adjacent to each other with the same display signal are controlled to emit light and the second pixel 121 which are adjacent to each other with the different display signals are controlled to emit light, and the first pixel 124 and the second pixel 123 which are adjacent to each other are controlled to emit light.
As shown in fig. 9, if the gray-scale data of the i+1th frame display is the same as the gray-scale data of the i+2th frame display, when the i+2th frame display is displayed, the second pixel 112 of the first pixel 111 and the second pixel 112 which are adjacent to each other and the display signal is the same are controlled to emit light and the first pixel 111 does not emit light, the second pixel 113 of the first pixel 113 and the second pixel 114 which are adjacent to each other and the display signal is controlled to emit light and the first pixel 113 does not emit light, the second pixel 121 of the first pixel 122 and the second pixel 121 which are adjacent to each other and the first pixel 124 and the second pixel 123 which are adjacent to each other and the display signal is different are controlled to emit light.
Therefore, compared with the situation that all pixels are controlled to display and emit light in each frame of display picture, the number of pixels for 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.
It should be noted that, the display signals of the first pixel and the second pixel that are adjacent to each other in the same row are compared, so that the display condition of each pixel in the i+1st frame of display screen is shown in fig. 8, and the display condition of each pixel in the i+2nd frame of display screen is shown in fig. 9; in the embodiment of the present invention, the first pixel and the second pixel which are adjacent to each other in the same column may be compared, and the technical principle is the same as that when the two adjacent pixels in the same row are compared, which is not described herein.
It can be understood that when one of two pixels adjacent to each other and having the same display signal is controlled to perform display light emission and the other pixel is not controlled to perform light emission, the display signal corresponding to the pixel may be provided to the pixel that emits light so that the pixel performs display light emission according to the display signal thereof, and no signal is provided to the pixel that does not emit light so that the pixel that does not emit light cannot perform display; alternatively, a display signal corresponding to a 0 gray scale value is supplied to a pixel that does not emit light so that the pixel that does not emit light exhibits the darkest luminance, and when the pixel exhibits the darkest luminance, the pixel may be regarded as not emitting light.
Alternatively, when two adjacent pixels are in the same row of pixels, or each pixel in the same column is in one 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.

S1212, when displaying the i+1th frame display screen, providing the display signal of the first alternate pixel in the i+1th frame display screen 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 i+1th frame display screen 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 i-th frame display screen is the same as the i+1th frame display screen, according to the gray-scale data of the i+1th frame display screen, 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 value corresponding to the data signal of each sub-pixel in the first pixel 111 and the second pixel 112 is 255), the first pixel 111 may be determined as a first alternate pixel, and the second pixel 112 may 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 each of the first pixel 123 and the second pixel 124 may be determined as a non-alternating pixel.
As shown in fig. 4, when displaying the i+1th frame display screen, a display signal of the first alternate pixel 111 in the i+1th frame display screen may be provided to the first alternate pixel 111, for example, a data signal corresponding to 255 gray-scale values is provided to each sub-pixel in the first alternate pixel 111, so that each sub-pixel in the first alternate pixel 111 is the brightest light-emitting brightness, and a display signal corresponding to 0 gray-scale value is provided to the second alternate pixel 112, that is, a data signal corresponding to 0 gray-scale value is provided to each sub-pixel in the second alternate pixel 112, so that each sub-pixel in the second alternate pixel 112 is the darkest light-emitting brightness; meanwhile, each of the non-alternating pixels 123 and 124 is supplied with its corresponding display signal, so that the alternating pixel 123 can display light of a corresponding luminance and color according to its display signal, and the alternating pixel 124 can display light of a corresponding luminance and color according to its display signal.
In general, the light-emitting brightness of each sub-pixel in each pixel in the display panel 100 is proportional to the power consumption of the sub-pixel, that is, the higher the light-emitting brightness of the sub-pixel is, the higher the power consumption of the sub-pixel is, therefore, when the light-emitting brightness of the sub-pixel is the light-emitting brightness corresponding to the 0 gray-scale value, the sub-pixel has the smallest power consumption compared with the light-emitting brightness corresponding to other gray-scale values. Thus, compared with the method that the display signals corresponding to the first alternating pixels and the second alternating pixels in the same pixel group are provided, when the display signals corresponding to the first alternating pixels are provided for the first alternating pixels in the same pixel group only 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; at the same time, the data signals corresponding to the non-alternating pixels are provided for the non-alternating pixels, so that the display panel can have good display effect.
Fig. 11 is a flowchart of a display control method for an i+2th frame display screen according to an embodiment of the present invention. As shown in fig. 11, the display control method of the i+2th frame display screen includes:
s1411, comparing display signals of two pixels in the same pixel group according to gray scale data of the i+2 frame display picture, determining a first pixel of the two pixels which belong to the same pixel group and have the same display signals as a first alternate pixel, determining a second pixel of the two pixels which belong to the same pixel group and have the same display signals as a second alternate pixel, and determining two pixels which belong to the same pixel group and have different display signals as non-alternate pixels.
S1412, when displaying the i+2th frame display screen, providing the display signal of the second alternate pixel in the i+2th frame display screen 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 i+2th frame display screen to the non-alternate pixel.
For example, also taking the case that the first pixels and the second pixels are alternately arranged only along the row direction, when the i+1th frame display screen and the i+2th frame display screen are identical, 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 i+2th frame display screen 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 i+1th frame display screen, and 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 i+1th frame display screen is omitted herein.
As shown in fig. 5, when displaying the i+2th frame display screen, a display signal of the second alternate pixel 112 in the i+2th frame display screen may be provided to the second alternate pixel 112, for example, a data signal corresponding to 255 gray-scale values is provided to each sub-pixel in the second alternate pixel 112, so that each sub-pixel in the second alternate pixel 112 is the brightest light-emitting brightness, and a display signal corresponding to 0 gray-scale value is provided to the first alternate pixel 111, that is, a data signal corresponding to 0 gray-scale value is provided to each sub-pixel in the first alternate pixel 111, so that each sub-pixel in the first alternate pixel 111 is the darkest light-emitting brightness; meanwhile, each of the non-alternating pixels 123 and 124 is supplied with its corresponding display signal, so that the alternating pixel 123 can display light of a corresponding luminance and color according to its display signal, and the alternating pixel 124 can display light of a corresponding luminance and color according to its display signal.
Thus, compared with the method that the display signals corresponding to the first alternate pixels and the second alternate pixels in the same pixel group are provided, when the display signals corresponding to the second alternate pixels are provided for the second alternate pixels in the same pixel group, and the display signals corresponding to the 0 gray scale value are provided for the first alternate 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 good display effect; in addition, when the three consecutive frames of display images are the same display image, the first alternate pixels and the second alternate pixels are controlled to perform alternate display in at least the two subsequent frames of display images, 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, each two adjacent pixels form a first pixel group in each pixel of the odd rows, and each two adjacent pixels form a second pixel group in each pixel of the same column; or, in each pixel in even number row, 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 odd 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; or, in each pixel in even number 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.

S1222, comparing the display signals of two pixels in the second pixel group according to the modified gray-scale data of the i+1th frame display picture, and modifying the display signals corresponding to the second pixel in the two pixels which belong to the same second pixel group and have the same display signals in the modified gray-scale data of the i+1th frame display picture into display signals corresponding to 0 gray-scale value, so as to obtain the gray-scale data of the modified i+1th frame display picture.
S1223, when displaying the i+1th frame display picture, providing display signals to each pixel in a one-to-one correspondence manner according to the gray scale data of the corrected i+1th frame display picture.
Fig. 13 is a schematic diagram illustrating a display control process of an i+1st frame display corresponding to fig. 12. As shown in fig. 13, taking two adjacent pixels in odd rows as an example, each two adjacent pixels form a first pixel group 101, and two adjacent pixels in the same column as each pixel in a second pixel group 102, for example, a first pixel 111 and a second pixel 112 form a first pixel group, a first pixel 113 and a second pixel 114 form a first pixel group, a first pixel 111 and a second pixel 121 form a second pixel group, a second pixel 112 and a first pixel 122 form a second pixel group, a first pixel 113 and a second pixel 123 form a second pixel group, and a second pixel 114 and a first pixel 124 form a second pixel group.
If the gray-scale data of the i-th frame display is the same as the gray-scale data of the i+1th frame display, and the display panel 100 displays the frame H11 according to the gray-scale data of the i+1th frame display, the display signals of two pixels in the same first pixel group, for example, the display signals of the first pixel 111 and the second pixel 112 in the same first pixel group and the display signals of the first pixel 113 and the second pixel 114 in the same first pixel group, may be compared according to the gray-scale data of the i+1th frame display; since the display signals of the first pixel 111 and the second pixel 112 belonging to the same first pixel group are the same, the display signals of the first pixel 113 and the second pixel 114 belonging to the same first pixel group are the same, so that the display signals of the second pixel 112 and the second pixel 114 can be modified to display signals corresponding to a 0 gray scale value, and gray scale data of the modified i+1st frame display picture can be obtained; when the gray-scale data of the modified i+1st frame display is used for display, each pixel in the display panel 100 presents a frame H12. Then, according to the modified gray-scale data of the i+1st frame display screen, comparing the display signals of two pixels in the same second pixel group, for example, comparing the display signals of the first pixel 111 and the second pixel 121 in the same second pixel group, comparing the display signals of the second pixel 112 and the first pixel 122 in the same second pixel group, comparing the display signals of the first pixel 113 and the second pixel 123 in the same second pixel group, and comparing the display signals of the first pixel 114 and the second pixel 124 in 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 to be the display signals corresponding to 0 gray scale, and the gray scale data of the i+1st frame display after correction can be obtained. When the i+1st frame display screen is displayed, a display signal is provided to each pixel of the display panel 100 according to the gray-scale data of the corrected i+1st frame display screen, so that each pixel in the display panel presents a screen H13. In this way, 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.
Fig. 14 is a flowchart of a display control method of an i+2th frame display screen according to an embodiment of the present invention. As shown in fig. 14, the display control method of the i+2th frame display screen includes:
s1421, comparing the display signals of two pixels in the first pixel group according to the gray-scale data of the i+2th frame display picture, and modifying the display signal corresponding to the first pixel in the two pixels belonging to the same first pixel group and having the same display signal in the gray-scale data of the i+2th frame display picture to a display signal corresponding to a 0 gray-scale value so as to obtain the modified gray-scale data of the i+2th frame display picture.
S1422, comparing the display signals of two pixels in the second pixel group according to the modified gray-scale data of the i+2th frame display picture, and modifying the display signals 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 i+2th frame display picture into display signals corresponding to 0 gray-scale value so as to obtain the gray-scale data of the modified i+2th frame display picture;
s1423, when displaying the i+2th frame display screen, providing display signals to each pixel in one-to-one correspondence according to the gray-scale data of the corrected i+2th frame display screen.
Fig. 15 is a schematic diagram illustrating a display control process of an i+2th frame display corresponding to fig. 14. As shown in fig. 15, in each pixel in the odd-numbered rows, two adjacent pixels each constitute a first pixel group 101, and two adjacent pixels each constitute a second pixel group 102 in each pixel in the same column. When the gray-scale data of the i+1th frame display screen is the same as the gray-scale data of the i+2th frame display screen, and the display screen H21 appears in each pixel in the display panel 100 when the display is performed according to the gray-scale data of the i+2th frame display screen, that is, the display signals of the first pixel 111 and the first pixel 113 can be modified to display signals corresponding to the 0 gray-scale value according to the gray-scale data of the i+2th frame display screen when the display is the same as the display according to the gray-scale data of the i+1th frame display screen, and the modified gray-scale data of the i+1th frame display screen is obtained; when the gray-scale data of the modified i+1st frame display is used for display, each pixel in the display panel 100 presents a frame H22. Then, according to the modified gray-scale data of the i+1th frame display screen, the display signals of the two pixels belonging to the same second pixel group are compared, so that the display signals of the second pixel 112 and the first pixel 121 of the same second pixel group are the same, and therefore the display signal of the first pixel 121 can be modified to be a display signal corresponding to 0 gray scale, and the gray-scale data of the modified i+2th frame display screen can be obtained. When the i+2 frame display screen is displayed, a display signal is provided to each pixel of the display panel 100 according to the gray-scale data of the corrected i+2 frame display screen, so that each pixel in the display panel presents a screen H23. In this way, 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.
The foregoing exemplifies the case where the gray-scale data of the i-th frame display is the same as the gray-scale data of the i+1th frame display, and the gray-scale data of the i+1th frame display is the same as the gray-scale data of the i+2th frame display, but in the embodiment of the present invention, when the gray-scale data of the i-th frame display is different from the gray-scale data of the i+1th frame display, and/or when the gray-scale data of the i+1th frame display is different from the gray-scale data of the i+2th frame display, 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 identical to the gray-scale data of the (i) -th frame display picture; if yes, executing S120; if not, S230 is performed.
S220, when the (i+1) th frame display picture is displayed, according to the gray scale data of the (i+1) th frame display picture, the first pixels in the first pixels and the second pixels which are the same in display signal and adjacent to each other are controlled to display, and the first pixels and the second pixels which are different in display signal and adjacent to each other are controlled to display.
S230, when the (i+1) th frame display picture is displayed, display signals are provided for the pixels in a one-to-one correspondence mode according to the gray scale data of the (i+1) th frame display picture.
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 identical with the gray-scale data of the (i+1) th frame display picture; if yes, executing S250; if not, S260 is performed.
S250, when the (i+2) th frame display picture is displayed, according to the gray scale data of the (i+2) th frame display picture, controlling the first pixels and the second pixels which are the same in display signal and adjacent to each other to display, and controlling the first pixels and the second pixels which are different in display signal and adjacent to each other to display.
S260, when the (i+2) th frame display picture is displayed, display signals are provided for the pixels in a one-to-one correspondence mode according to the gray scale data of the (i+2) th frame display picture.
Thus, when the gray-scale data of the i-th frame display picture is the same as the gray-scale data of the i+1th frame display picture and the gray-scale data of the i+1th frame display picture are the same, the first pixels and the second pixels which are adjacent and have the same display signals can be controlled to be alternately displayed in the i+1th frame display picture and the i+2th frame display picture respectively so as to reduce the power consumption of the display picture; if the gray-scale data of the i-th frame display picture is different from the gray-scale data of the i+1th frame display picture, when the i+1th frame display picture 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+1th frame display picture, so that the display panel can display the complete picture of the i+1th frame; and/or if the gray-scale data of the i+1th frame display picture is different from the gray-scale data of the i+2th frame display picture, when the i+2th frame display picture 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+2th frame display picture, so that the display panel can display the complete picture of the i+2th frame, and the display panel has better display effect.
Optionally, when the gray-scale data of the i+1th frame display screen is the same as the gray-scale data of the i frame display screen, the refresh frequency from the i frame display screen to the i+1th frame display screen is switched to the first refresh frequency; when the gray-scale data of the (i+1) -th frame display picture is different from the gray-scale data of the (i) th frame display picture, switching the refreshing frequency from the (i) th frame display picture to the (i+1) -th frame display picture to be a second refreshing frequency; and/or when 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, switching the refreshing frequency from the (i+1) -th frame display picture to the (i+2) -th frame display picture to be the first refreshing frequency; when the gray scale data of the (i+2) -th frame display picture is different from the gray scale data of the (i+1) -th frame display picture, switching the refreshing frequency from the (i+1) -th frame display picture to the (i+2) -th frame display picture to be a second refreshing frequency; wherein the second refresh frequency is greater than the first refresh frequency.
Since the power consumption of the display panel is positively correlated with the refresh frequency, the higher the power consumption of the display panel; therefore, when the gray-scale data of two adjacent frames of display pictures are the same, the refresh frequency of the display panel can be properly reduced, so that the power consumption of the display panel can be reduced. Meanwhile, the higher the refresh frequency of the display panel is, the shorter the update time of the display picture of the display panel is, namely, when the gray scale data of two adjacent frames of display pictures are different, the refresh frequency of the display panel can be properly improved, so that the display panel can have better display quality.
When the second refresh rate is greater than the first refresh rate, the second refresh rate may be an integer multiple of the first refresh rate, i.e., the second refresh rate may be m times the first refresh rate, where m is a positive integer. For example, when the second refresh frequency is 30Hz, the first refresh frequency may be 15Hz.
It should be noted that, the foregoing is merely illustrative, and when the gray-scale data of the current frame display screen to be displayed is different from the gray-scale data of the previous frame display screen, all the pixels in the display panel may be refreshed according to the gray-scale data of the current frame display screen when the current frame display screen 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 used.
Optionally, if the gray-scale data of the i+1th frame display screen is different from the gray-scale data of the i frame display screen, determining updated pixels and non-updated pixels in each pixel according to the gray-scale data of the i+1th frame display screen and the gray-scale data of the i frame display screen; wherein the updated pixel is a pixel in which the display signal in the i+1st frame display screen is different from the display signal in the i frame display screen; the non-updated pixels are pixels in which the display signal in the i+1th display screen is the same as the display signal in the i-th frame display screen; when the i+1th frame display picture is displayed, according to the gray-scale data of the i+1th frame display picture, the first pixels in the first pixels and the second pixels which are adjacent and have the same display signals in the non-updated pixels are controlled to display, the first pixels and the second pixels which are adjacent and have different display signals in the non-updated pixels are controlled to display, and the updated pixels are controlled to display.
Fig. 17 is a schematic diagram of another display screen according to an embodiment of the present invention. Taking fig. 3 as a frame presented according to the gray-scale data of the i-th frame display frame, fig. 17 as an example of a frame presented according to the gray-scale data of the i+1th frame display frame. Referring to fig. 3 and 17 in combination, the i-th frame display displays the numeral "21" in the white background, and the i+1-th frame display displays the numeral "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 i+1-th frame display are changed compared to the gray-scale data of the i-th frame display, so that the pixels 121, 122, 123, 125, 131, 134, 141, 142, 143, 145, 154, 155, 161, 162, 163, and 165 are updated pixels and the other pixels are non-updated pixels.
Fig. 18 is a schematic diagram of another i+1st frame display according to an embodiment of the present invention. As shown in fig. 17 and 18, when displaying the i+1th frame display screen, the pixels 121, 122, 123, 125, 131, 134, 141, 142, 143, 145, 154, 155, 161, 162, 163, and 165 may be controlled to display, while the first pixel of the two pixels adjacent to each other among the non-updated pixels and having the same display signal is controlled to display, and the pixels adjacent to each other among the other non-updated pixels and having different display signals are controlled to display.
In this embodiment, when the i-th frame display screen is different from the i+1th frame display screen in part of gray scale data, a display signal is provided to each update pixel in a one-to-one correspondence manner, and a first pixel of two pixels, which are adjacent and have the same display signal, is not kept to be adjacent, and two pixels, which are adjacent and have different display signals, are displayed; in this way, even if the i-th frame display screen is different from the i+1-th frame display screen in gray-scale data, the number of pixels for display light emission can be reduced when the i-th frame display screen is displayed, thereby reducing power consumption of the display panel and improving display effect of the display panel.
Optionally, when the gray-scale data of the i+1th frame display screen is different from the gray-scale data of the i+1th frame display screen, when the i frame display screen is switched to the i+1th frame display screen, a display signal is provided to each updated pixel at a second refresh frequency, and a display signal is provided to each pixel displayed in each non-updated pixel at a first refresh frequency; wherein the second refresh frequency is greater than the first refresh frequency. At this time, when the i-th frame display screen is switched to the i+1-th frame display screen, the time required for the updated pixel to obtain the display signal corresponding to the updated pixel is smaller than the time required for each pixel displayed in the non-more pixels to obtain the display signal corresponding to the non-more pixels, so that the content displayed by the updated pixel can be displayed in time, and the display effect of the display panel can be improved; meanwhile, since the higher the refresh frequency is, the higher the power consumption of the display panel is, when the display signal of the non-updated pixel is refreshed at a smaller refresh frequency, the power consumption of the display panel can be further reduced.
Similarly, if the gray-scale data of the i+2th frame display screen is different from the gray-scale data of the i+1th frame display screen, determining updated pixels and non-updated pixels in each pixel according to the gray-scale data of the i+2th frame display screen and the gray-scale data of the i+1th frame display screen; wherein the updated pixel is a pixel having a display signal in the i+2th frame display screen different from a display signal in the i+1th frame display screen; the non-updated pixels are pixels in which the display signal in the i+2-th display screen is the same as the display signal in the i+1-th display screen; when the i+2th frame display picture is displayed, according to the gray-scale data of the i+2th frame display picture, controlling the second pixels in the first pixels and the second pixels which are adjacent and have the same display signals in the non-updated pixels to display, controlling the first pixels and the second pixels which are adjacent and have different display signals in the non-updated pixels to display, and controlling the updated pixels to display.
Fig. 19 is a schematic view of another display screen according to an embodiment of the present invention, and fig. 20 is a schematic view of another i+2th frame display screen according to an embodiment of the present invention. Taking fig. 17 as an example of a frame presented according to the gray-scale data of the i+1th frame display frame, fig. 19 as an example of a frame presented according to the gray-scale data of the i+2th frame display frame. Referring to fig. 17, 19 and 20 in combination, the i+1st frame display displays the numeral "22" in the white background, and the i+2nd frame display displays the numeral "23" in the white background, that is, the display signals corresponding to the pixels 151 and 155 in the gray-scale data of the i+2th frame display are changed compared to the gray-scale data of the i+1st frame display, so that the pixels 151 and 155 are updated pixels and the other pixels are non-updated pixels. When displaying the i+2th frame of display screen, the controllable pixels 151 and 155 are both controlled to display, and the second pixel of the two pixels adjacent to each other among other non-updated pixels and having the same display signal is controlled to display, and the pixels adjacent to each other among other non-updated pixels and having different display signals 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.
Optionally, when the gray-scale data of the i+2th frame display screen is different from the gray-scale data of the i+1th frame display screen, when the i+1th frame display screen is switched to the i+2th frame display screen, a display signal is provided to each updated pixel at a second refresh frequency, and a display signal is provided to each pixel displayed in each non-updated pixel at a first refresh frequency; wherein the second refresh frequency is greater than the first refresh frequency. At this time, the content displayed by the updated pixels can be displayed in time, so that the display effect of the display panel is improved, and the power consumption of the display panel is further reduced.
