Background
Because the attenuation rules of the light with different wavelengths are different, when a user views the display panel under a large viewing angle, a color cast phenomenon is generated, and the display effect is reduced.

Fig. 1 is a schematic diagram of a display panel according to an embodiment of the present application, and fig. 2 is a flowchart of a driving method of a display panel according to an embodiment of the present application.
An embodiment of the present application provides a driving method of a display panel 100, as shown in fig. 1 and 2, including:
S1: and acquiring a user view angle.
The user viewing angle is an angle at which the user views the display panel 100 when using the display panel 100.
The display panel 100 may include a viewing angle judging module therein, which can recognize a user's viewing angle. The viewing angle judging module may include an information acquisition component capable of identifying human eye characteristics, such as a camera module, and an information processing component for calculating a user viewing angle according to the human eye characteristics. The viewing angle judging module in the display panel 100 obtains the viewing angle of the user after obtaining the human eye characteristics when the user views the display panel 100.
S2: according to the visual angle of the user, determining a brightness compensation value A1 of the target color pixel X;
The display panel includes a plurality of pixels of different colors, and color cast conditions observed by a user at different viewing angles are different. The pixels that need to be brightness compensated may be pixels of different colors and/or the same color pixels may need to be brightness compensated differently when the user viewing angles detected at different times are different. The target color pixel X is a color pixel determined based on the currently acquired user visual angle; in addition, there may be other color pixels in the currently acquired user viewing angle that need to be compensated for brightness, and the other color pixels may also be used as the target color pixels.
The luminance compensation value A1 may be a coefficient for gain-compensating the light emission luminance of the target color pixel X.
When the user viewing angles of the display screen of the display panel 100 are different, the attenuation degree of the light emitted by the same color pixel is also different, and the brightness compensation value A1 corresponding to the target color pixel X in the display panel 100 is also different. In general, when the user viewing angle is larger, the attenuation degree of the light emitted by the same color pixel is larger, and if brightness compensation is required for the color pixel, the brightness compensation value A1 for the color pixel should also be larger.
The brightness compensation values of the pixels with the same color under different viewing angles can be pre-stored in the storage module, and the brightness compensation values of the pixels with the same viewing angle, which are required to be subjected to brightness compensation, can be pre-stored in the storage module. And determining a brightness compensation value A1 of the target color pixel X according to the user view angle, namely calling the brightness compensation value corresponding to the target color pixel in a pre-storing module according to the user view angle.
Fig. 3 is a flowchart of a test for obtaining a brightness compensation value according to an embodiment of the present application.
Illustratively, the process of obtaining the brightness compensation value A1 corresponding to the different color pixels X, as shown in fig. 3, includes:
Simulating a user viewing angle by using a brightness measuring device such as a spectrometer, and measuring the display brightness of pixels with different colors in the display panel 100 under the same user viewing angle; and further simulate different user viewing angles to obtain display brightness under different user viewing angles.
According to the display brightness and the preset brightness corresponding to each color pixel obtained through measurement, determining a brightness attenuation value between the preset brightness and the measured brightness corresponding to each color pixel respectively;
And converting the brightness attenuation values corresponding to the color pixels into brightness compensation values A1 corresponding to the color pixels, and burning the brightness compensation values A1 into the storage module. The memory module may be a memory module in the driver I C that drives the display panel 100 to perform light-emitting display.
S3: determining a target display brightness parameter L2 of the target color pixel X according to the brightness compensation value A1 of the target color pixel X;
The brightness compensation value A1 obtained by the application can be used for compensating the picture to be displayed. The target color pixel X in the image to be displayed has its corresponding preset display brightness, and in order to improve color shift, the preset display brightness of the target color pixel X in the image to be displayed can be superimposed by the compensation brightness, so as to obtain the target display brightness parameter L2 of the target color pixel X.
The driving IC pre-stores a plurality of preset display brightness parameters for respectively driving the pixels to realize different light-emitting brightness, that is, the driving I C can drive the pixels to emit light with different brightness according to the preset display brightness parameters, and the preset display brightness parameters correspond to the display brightness before the pixels are compensated. After the brightness compensation value of the target display pixel is obtained, the target display brightness parameter L2 of the target color pixel X may be determined based on the display parameter compensation value and the preset display brightness parameter of the target color pixel X. The brightness of the target color pixel X driven by the preset display brightness parameter is the actual display brightness before compensation, the target display parameter corresponds to the target brightness, and the target brightness is the brightness after compensation.
Alternatively, the display brightness parameter L2 may be one of gray scale and data voltage.
S4: the target color pixel X is light-driven based on the target display luminance parameter L2 of the target color pixel X.
As can be seen from the above, after the target display luminance parameter L2 of the target color pixel X is determined, the target display luminance parameter L2 can be output to the display panel 100 to drive the target color pixel X to emit light, and the light emission effect thereof can be improved.
In an embodiment of the present application, a driving method of a display panel 100 is provided to improve the color shift problem of the display panel 100. The method can acquire the user viewing angles, and perform different brightness compensation on the target color pixels X under different user viewing angles, so that the brightness compensation on the target color pixels X is more accurate, the brightness compensation is performed on different target color pixels X and different user viewing angles correspondingly, the situation that the brightness attenuation degree is different under different viewing angles and different colors is effectively processed, the reliability of color cast is improved, the situation that overcompensation or undercompensation occurs when brightness compensation is performed on some target color pixels X is avoided, and the display effect of the display panel 100 under different user viewing angles is further improved.
Fig. 4 is a flowchart of determining a brightness compensation value according to an embodiment of the present application.
In one embodiment of the present application, as shown in fig. 4, determining the brightness compensation value A1 of the target color pixel X according to the user's viewing angle includes:
SS1: the refresh frequency of the display panel 100 in a target period of time, which is a period in which the target color pixel X is driven to emit light based on the target display luminance parameter L2 of the target color pixel X, that is, a period in which the target color pixel X needs to be luminance-compensated for to be displayed on a screen to be displayed, is acquired. The refresh frequency of the display panel 100 in the target period T1 is that of the screen to be displayed in which the brightness compensation is required for the target color pixel X.
Since the degree of attenuation of the same color pixels in the display panel 100 is different when the refresh frequency of the display panel 100 is different. In general, when the display panel 100 performs low-frequency display, that is, the refresh frequency is low, the light emission luminance of each color pixel is greatly attenuated in one frame of display screen, and the attenuation difference of the light emission luminance of different color pixels is also related to the refresh frequency. Therefore, the refresh frequency is also taken into consideration when performing brightness compensation for the target color pixel X in the display panel 100.
Then, when the luminance compensation value A1 of each color pixel in the display panel 100 is acquired by the analog test, luminance measurement for different refresh frequencies is also required. According to the display brightness at different refresh frequencies and different user viewing angles, brightness compensation values A1 corresponding to the pixels of each color in the display panel 100 are obtained at different refresh frequencies and different user viewing angles.
SS2: according to the user viewing angle, the brightness compensation value A1 of the target color pixel X is determined based on the refresh frequency.
As described above, the luminance compensation value A1 pre-stored in the memory module is related to not only the user viewing angle but also the refresh frequency, and when the luminance compensation value in the memory module is related to both the user viewing angle and the refresh frequency, the luminance compensation value A1 acquired from the memory module may be different when the acquired user viewing angle is the same and the refresh frequency is different.
In the embodiment of the application, the refresh frequency of the target color pixel X working in the target time period is obtained, the brightness compensation value A1 of the target color pixel X is determined according to the user visual angle and the refresh frequency, and a plurality of factors influencing the display brightness of the target color pixel X are considered, so that the brightness compensation value X of the target color pixel X is more accurate, the brightness compensation effect on the target color pixel X is improved, the situation that the brightness compensation of the target color pixel X is deficient or overcompensated under different refresh frequencies is avoided, the color cast is improved better, and the display effect of the display panel 100 is improved.
Fig. 5 is a schematic diagram of a display panel according to an embodiment of the application.
In one embodiment of the present application, determining the brightness compensation value A1 of the target color pixel X according to the user viewing angle includes:
according to the user viewing angle, a first luminance compensation value of the first target color pixel X10 and a second luminance compensation value of the second target color pixel X20 are determined, the first luminance compensation value and the second luminance compensation value being different.
Optionally, the first luminance compensation value and the second luminance compensation value are the same.
As shown in fig. 5, the target color pixel X in the display panel 100 may include different kinds of first color pixels X110 and second color pixels X120. The first color pixel X110 and the second color pixel X120 may have different brightness attenuation degrees at the same user viewing angle.
Then, after determining the user viewing angle, the first brightness compensation value is invoked to perform brightness compensation on the first target color pixel X10, and the second brightness compensation value is invoked to perform brightness compensation on the second target color pixel X20.
In one technical scheme, under the same user viewing angle, a plurality of first target color pixels X10 with the same color all call the same first brightness compensation value, and a plurality of second target color pixels X20 with the same color all call the same second brightness compensation value. The method is beneficial to reducing the workload when a plurality of first compensation values A1 are called, reducing the workload of the display panel 100, improving the operation efficiency and reducing the influence of color cast to a certain extent.
In one technical scheme, under the same user viewing angle, a first brightness compensation value and a second brightness compensation value which are in one-to-one correspondence with a plurality of first target color pixels X10 and a plurality of second target color pixels X20 are called.
Under the same user viewing angle, the first target colors X10 and the second target colors X20 at different positions in the display panel 100 may generate different brightness attenuation degrees, so that the technical scheme can effectively cope with the situation, is favorable for accurately compensating the brightness of each target color pixel X, and better improves the color cast effect under different user viewing angles.
Fig. 6 is a schematic diagram of another display panel according to an embodiment of the application.
In one embodiment of the present application, determining the brightness compensation value A1 of the target color pixel X according to the user viewing angle further includes:
Determining a third brightness compensation value of a third target color pixel X30 according to the user viewing angle; the third luminance compensation value of the third target color pixel X30 is equal to the second luminance compensation value of the second target color pixel X20.
Optionally, the third luminance compensation value of the third target color pixel X30 is not equal to the second luminance compensation value of the second target color pixel X20.
As shown in fig. 6, the target color pixels X in the display panel 100 further include third target color pixels X30.
In the determination of the user viewing angle, there is a case where the second target color pixel X20 and the third target color pixel X30 have similar degrees of luminance decay.
Then, after determining the user viewing angle, the first brightness compensation value is invoked to perform brightness compensation on the first target color pixel X10, the second brightness compensation value is invoked to perform brightness compensation on the second target color pixel X20, and the compensation proportion of the brightness of the first target color pixel X10 and the brightness of the second target color pixel X20 are the same.
In the embodiment of the application, the third brightness compensation value of the third target color pixel X30 is equal to the second brightness compensation value of the second target color pixel X20, which is favorable for reducing the number of the stored brightness compensation values A1, reducing the occupied space of the brightness compensation values A1, reducing the complexity of brightness compensation work and improving the brightness compensation efficiency.
In one embodiment of the present application, with continued reference to FIG. 6, the first target color pixel X10 is a blue pixel, the second target color pixel X20 is a red pixel, and the third target color pixel X30 is a green pixel.
In the display panel 100, three color pixels in which the red pixel and the green pixel have similar brightness decay degrees at the same user viewing angle are included.
In one embodiment, since the brightness attenuation degrees of the second target color pixel X20 and the third target color pixel X30 at the same user viewing angle are similar, the second target color pixel X20 and the third target color pixel X30 share the brightness compensation value A1 at the same viewing angle.
In one embodiment of the present application, the first luminance compensation value of the first target color pixel X10 is greater than the second luminance compensation value of the second target color pixel X20.
In the display process of the display panel 100, the brightness of the blue pixel is greatly attenuated due to the structure and the material property of the blue pixel. In general, the brightness of a blue pixel decays more than red and green pixels at the same user viewing angle. The first brightness compensation value of the first target color pixel X10, i.e., the blue pixel, is set to be larger. The first brightness compensation value of the first target color pixel X10 is made larger than the second brightness compensation value of the second target color pixel X20, and since the second brightness compensation value of the second target color pixel X20 can be the same as the third brightness compensation value of the third target color pixel X30, the first brightness compensation value of the first target color pixel X10 is larger than the second brightness compensation value and the third brightness compensation value.
Of course, alternatively, the first luminance compensation value of the first target color pixel X10, the second luminance compensation value of the second target color pixel X20, and the third luminance compensation value of the third target color pixel X30 are all set to be equal at the same user viewing angle.
In the embodiment of the application, the first brightness compensation value of the first target color pixel X10 is set to be larger than the second brightness compensation value of the second target color pixel X20, so that larger brightness compensation is provided for the first target color pixel X10, the condition that the brightness attenuation degree of the first target color pixel X10 is larger is satisfied, the accurate compensation degree for the target color pixel X is improved, and the color cast is better improved.
Fig. 7 is a flowchart of determining a target display brightness parameter according to an embodiment of the present application.
In one embodiment of the present application, as shown in fig. 7, determining the target display luminance parameter L2 of the target color pixel X according to the luminance compensation value A1 of the target color pixel X includes:
SA1: acquiring preset display brightness L1 corresponding to a target color pixel X;
The brightness attenuation degree of the corresponding target color pixel X is compensated according to the brightness attenuation proportion on the basis of the preset display brightness L1 of the target color pixel X. The preset display brightness L1 corresponding to the target color pixel X is data such as gray scale, data voltage, etc. of the preset driving target color pixel X displayed without brightness attenuation in the display screen after the current display screen.
SA2, obtaining a target display brightness parameter L2 of the target color pixel X based on the brightness compensation value A1 of the target color pixel X and the preset display brightness L1 corresponding to the target color pixel X.
The target display luminance parameter L2 is data such as gray scale, data voltage, etc. of the target color pixel X which can be driven to perform higher-level light-emitting luminance display in the display screen after the current display screen, so that the luminance attenuation of the target color pixel X can be compensated to a certain extent.
After determining the brightness compensation value A1 corresponding to the target color pixel X and the preset display brightness L1 under the user viewing angle, obtaining the brightness compensation degree required to be made on the target color pixel X, and further making certain compensation on the basis of the preset display brightness L1 to obtain the target display brightness parameter L2.
In one embodiment of the present application, with continued reference to fig. 7, the brightness compensation value A1 of the target color pixel X, the preset display brightness L1 corresponding to the target color pixel X, and the target display brightness parameter L2 of the target color pixel X satisfy:
L2＝A1*L1+L1。
wherein, A1X L1 is compensation for the brightness of the target color pixel X based on the preset display brightness L1, and then adding the compensation to the preset display brightness L1 to obtain the target display brightness parameter L2.
After the target display brightness parameter L2 of the target color pixel X is obtained, the target color pixel X is driven to perform luminescent display according to the target display brightness parameter L2, and the brightness of the luminescent display performed by driving the target color pixel X according to the target display brightness parameter L2 can effectively improve the color cast phenomenon under a large viewing angle.
