Abstract
The present disclosure provides a digital driving method and a digital driving system of an OLED display device. The digital driving method includes: dividing the frame into N sub frames, wherein N is an integer larger than or equal to 2, one of the sub frames is a full-brightness sub frame, the full-brightness sub frame includes a full-emission sub frame and the blanking period, pixels of the OLED display device keep emitting lights within the full-emission sub frame, and the blanking period follows the full-emission sub frame; determining the time ratios of driving the pixels in the sub frames as ½, ½. . . , 1 to increase the luminance of the OLED display device, wherein the time ratio of driving the pixels in the full-brightness sub frame is 1. By using the present disclosure, the brightness uniformity of the OLED display device can be increase.
