摘要： A display driving method includes: determining, by a timing controller, an actual grayscale value of a sub-pixel image in an X-th row and a Y-th column according to a preset grayscale value of a sub-pixel image in an (X−1)-th row and the Y-th column and a preset grayscale value of the sub-pixel image in the X-th row and the Y-th column of an image frame to be displayed. The image frame to be displayed includes J rows and Q columns of sub-pixel images. X is greater than or equal to 2, and is less than or equal to J. Y is greater than or equal to 1, and is less than or equal to Q, and X, Y, J, and Q are all integers.

摘要： A control method of a display apparatus is provided. The method includes: obtaining to-be-displayed data; starting to generate first image data of a first display panel based on the to-be-displayed data; sending image data to a second processing component based on the to-be-displayed data; and after generating the first image data, delaying sending the first image data to the first display panel based on a first difference between second duration taken by the second processing component to generate second image data and first duration taken by a first processing component to generate the first image data.
