Abstract
A display apparatus includes a display panel, a memory, and a driver. The memory stores at least one set of correspondences, and each set of correspondences includes 2N grayscale data and 2N register values in a one-to-one correspondence with the 2N grayscale data; each register value represents a grayscale voltage value of corresponding grayscale data; and N is a positive integer greater than or equal to 6. The driver obtains the at least one set of correspondences from the memory; receives image data from a signal transmission interface, the image data including a plurality of grayscale data corresponding to a plurality of sub-pixels; for any grayscale data in the image data, obtains a register value corresponding to the grayscale data in a set of correspondences; and outputs a grayscale voltage corresponding to a grayscale voltage value represented by the register value to the display panel according to the register value.
