Abstract

A display driving method, a display driver and a display device are provided. The display driving method includes acquiring a first grayscale of at least one to-be-displayed sub-pixel, performing a first compensation manner to compensate the first grayscale and acquire a second grayscale, determining whether the second grayscale is less than a critical value; if yes, performing a second compensation manner to compensate the second grayscale and acquire a third grayscale, and acquiring a data voltage based on the third grayscale to control the sub-pixel to emit light and display, and if no, acquiring a data voltage based on the second grayscale to control the sub-pixel to emit light and display. The problem of displaying color deviation when the display panel is displayed at a low grayscale can be avoided.
