0-255 grayscale is divided into 8 sections, respectively 0-32 grayscale, 32-64 grayscale, 64-96 grayscale, 96- by Tables 1 and 2
128 grayscale, 128-160 grayscale, 160-192 grayscale, 192-224 grayscale and 224-255 grayscale.What is recorded in Tables 1 and 2 is
Two endpoint grayscale values corresponding gray scale compensation value in variation in every section, can be with for the gray scale compensation value between two endpoints
It is obtained by linear algorithm, the application does not limit specifically.In third display area, sub-pixel shows previous grayscale value
It is 0, current gray value 32, in order to avoid there is colour cast, then in requisition for output gray scale compensation value 37, i.e., compensated grayscale is mended
Value bigger than current gray offset 5 is repaid to avoid colour cast；Since third display area is in the middle position of display panel, colour cast journey
Spend less than the first display area colour cast degree, sub-pixel from previous grayscale value 0 variation be current gray value 32 when, first
It accordingly needs to export gray scale compensation value 40 in display area, i.e., compensated gray scale compensation value is bigger than current gray offset by 8.
It should be noted that current gray value be 0 when, though previous grayscale value be it is how many, gray scale compensation value is 0；Current gray
When value is 255, and though previous grayscale value be it is how many, gray scale compensation value is 255；Current gray value and previous grayscale value are same
When being 32,64,96,128,160,192,224, gray scale compensation value is identical as current gray value.
