Abstract
A grayscale data compensation method and apparatus and a driver chip. The grayscale data compensation method includes acquiring an input display brightness instruction value; determining a coefficient variation value corresponding to the input display brightness instruction value according to a relationship in magnitude between the input display brightness instruction value and a range boundary instruction value corresponding to a range boundary; and compensating grayscale data according to the coefficient variation value and a reference compensation coefficient pre-stored under a standard brightness instruction value.
