Abstract
A pixel compensation method includes: detecting driving transistors of pixels to obtain present characteristic values of the driving transistors of the pixels; extracting historical compensation characteristic values of the driving transistors of the pixels obtained in a previous display cycle of a screen; calculating a present compensation characteristic value of at least one driving transistor of the pixels according to a present characteristic value and a historical compensation characteristic value corresponding to the driving transistor of the pixels; and compensating a corresponding pixel according to the present compensation characteristic value of the driving transistor of the pixels.
