Abstract
The present disclosure discloses a grayscale signal compensation unit, a grayscale signal compensation method, a source driver, and a display apparatus. The grayscale signal compensation unit comprises: a compensation coefficient determination sub-unit configured to determine a compensation coefficient according to a position of a pixel to be driven; an inquiry sub-unit configured to inquire a reference compensation value corresponding to the initial grayscale signal according to a pre-stored grayscale compensation correspondence table for a row of pixels farthest from the source driving circuit, wherein the grayscale compensation correspondence table contains different grayscale signals and corresponding reference compensation values thereof; a calculation sub-unit configured to calculate an actual compensation value corresponding to the pixel to be driven according to the compensation coefficient and the inquired reference compensation value; and a compensation sub-unit configured to compensate for the initial grayscale signal according to the actual compensation value.
