Abstract
The display apparatus includes a plurality of sub-pixels. The control method includes: calculating a compensation data signal of each compensation sub-pixel according to a position of at least one dead sub-pixel adjacent to the compensation sub-pixel in the display apparatus, a data signal of each dead sub-pixel adjacent to the compensation sub-pixel in a current frame image, and a number of compensation sub-pixels in all sub-pixels that have a same emission color as and are adjacent to each dead sub-pixel; calculating a total data signal for the compensation sub-pixel according to a data signal of the compensation sub-pixel in the current frame image and the calculated compensation data signal of the compensation sub-pixel; and inputting the total data signal to the compensation sub-pixel when the current frame image is displayed.
