Abstract: A display drive method is applied to a display panel. The display panel has a subpixel used for image display. The display drive method includes obtaining a to-be-displayed grayscale of a to-be-displayed subpixel, selecting a suitable compensation manner based on the to-be-displayed grayscale, and providing a data voltage for the to-be-displayed sub-pixel based on the selected compensation manner. The compensation manner includes a first compensation manner and a second compensation manner. When the to-be-displayed grayscale is 0 grayscale, the first compensation manner is selected. When the to-be-displayed grayscale is greater than 0 grayscale, the second compensation manner is selected. The first compensation manner is used to reduce a difference between light-emitting efficiencies of sub-pixels with different light-emitting colors under a same grayscale.
