and S11, judging whether the brightness attenuation degree of the pixels on the panel reaches a preset threshold value of the initial brightness.
In this embodiment, the attenuation degree of the R/G/B three-color OLED device is estimated by using a basic method of display data counting, and then the color shift condition (change of R/G/B luminance ratio) at the current attenuation degree is obtained by calculation, and it is first determined whether a luminance compensation threshold (compensation start point) is reached. For example: setting a brightness compensation interval of 0.8-1. If there is a pixel having the brightness attenuation degree reaching the preset threshold value of the initial brightness, the step S12 is executed, and if there is no pixel having the brightness attenuation degree reaching the preset threshold value of the initial brightness, the step S13 is executed.
And S12, if the pixels with the brightness attenuation degree reaching the preset threshold value of the initial brightness exist, performing brightness compensation on each pixel on the panel.
In this embodiment, the brightness compensation has the highest priority, and when the brightness attenuation degree of the R/G/B pixel on the panel reaches 80% of the initial brightness, the brightness compensation is performed, and the brightness compensation is performed on the entire panel. Each pixel is represented by coordinates (x, y, z), wherein the coordinates x, y and z respectively represent the number of rows and columns and the pixel type, z is 1 for R, z is 2 for G, z is 3 for B, and the compensation coefficient is L0L (x, y, z), thereby achieving accurate compensation of the device luminance for each pixel.
And S13, if there is no pixel with the brightness attenuation degree reaching the preset threshold value of the initial brightness, compensating the color cast of the OLED.
In this embodiment, the color shift compensation has a lower priority than the brightness compensation, and when the brightness attenuation degree of the R/G/B pixel on the panel does not reach 80% of the initial brightness, the color shift compensation is performed.

In this embodiment, the attenuation degree of the R/G/B three-color OLED device is estimated by using a basic method of display data counting, and then the color shift condition (change of R/G/B luminance ratio) at the current attenuation degree is obtained by calculation, and it is first determined whether a luminance compensation threshold (compensation start point) is reached. For example: setting a brightness compensation interval of 0.8-1. Specifically, if there is a pixel whose brightness attenuation degree reaches the preset threshold value of the initial brightness, step S22 is executed, and if there is no pixel whose brightness attenuation degree reaches the preset threshold value of the initial brightness, step S23 is executed.
And S22, performing brightness compensation on each pixel on the panel.
In the present embodiment, the luminance compensation is performed on each pixel on the panel by increasing the driving current to compensate the luminance of each pixel to be consistent with the initial luminance.

In this embodiment, the color shift compensation has a lower priority than the brightness compensation, and when the brightness attenuation of the R/G/B pixel on the panel does not reach 80% of the initial brightness, the brightness attenuation of the R/G/B sub-pixel in each pixel is calculated first.
And S24, judging whether the brightness attenuation degree difference of any two sub-pixels in each pixel is within a preset range.
In this embodiment, the difference determination condition of the color shift compensation scheme is set to 0.01, specifically, if the difference between the luminance attenuation degrees of any two sub-pixels in each of the pixels is within a preset range, step S25 is executed, and if the difference between the luminance attenuation degrees of any two sub-pixels in each of the pixels is outside the preset range, step S26 is executed.
