Abstract
A display device including a driving chip and a pixel array is provided. The driving chip is configured to provide multiple emission control signals according to a data input. A pixel array is coupled with the driving chip. M pixel circuits of the pixel array are configured to emit light respectively in M periods, and M is a positive integer. In a corresponding period of the M periods, the driving chip determines a first time length which one of the multiple emission control signals has a first voltage level, and one of the M pixel circuits emits light, in the corresponding period, for a light emission time length corresponding to the first time length.
