Abstract
A display panel and its brightness compensation method, brightness compensation system, and display device. The display panel includes pixel units, each pixel unit including a first color sub-pixel, a second color sub-pixel, a third color sub-pixel, and a white sub-pixel. The brightness compensation method includes: receiving the original brightness data of the first color sub-pixel, the second color sub-pixel, and the third color sub-pixel; calculating the brightness of the white sub-pixel according to the formula W = a × min(L1, L2, L3); and calculating the compensated brightness of the first color sub-pixel, the compensated brightness of the second color sub-pixel, and the compensated brightness of the third color sub-pixel based on the brightness of the white sub-pixel. Wherein, a is an adjustable coefficient, and a can be adjusted according to the type of display panel; L1 is the original brightness of the first color sub-pixel; L2 is the original brightness of the second color sub-pixel; L3 is the original brightness of the third color sub-pixel; and min(L1, L2, L3) is a function to take the minimum value.
