Abstract
The present application provides a display device, which includes a display panel, a gate driver, and an emission driver. In a first duration corresponding to a writing frame and each holding frame, a ratio of number of periods of a light-emitting control signal to a first duration is greater than a critical flicker frequency. A valid pulse of the first scan signal corresponds to an invalid pulse of the light-emitting control signal, and a valid pulse of the second scan signal is located within a duration of the invalid pulse in the first period of the light-emitting control signal corresponding to the writing frame.
Claims11
A display device, comprising:
- a display panel, comprising multiple sub-pixels;
- a gate driver, comprising a first gate driving unit and a second gate driving unit, the first gate driving unit being configured to output a first scan signal to the sub-pixels, the second gate driving unit being configured to output a second scan signal to the sub-pixels;
- and
- an emission driver, configured to output a light-emitting control signal to the sub-pixels;
- wherein the display panel has multiple display periods, at least one of the display periods comprises a writing frame and multiple holding frames, the writing frame and each of the multiple holding frames both have a first duration;
- within the writing frame and each of the multiple holding frames, the light-emitting control signal has multiple periods, a ratio of number of the periods of the light-emitting control signal to the first duration is greater than a critical flicker frequency;
- and
- the light-emitting control signal has a valid pulse and an invalid pulse in each period, the first scan signal has a valid pulse during a duration of the invalid pulse of the light-emitting control signal in the writing frame and the multiple holding frames, the second scan signal has a valid pulse during a duration of the invalid pulse in a first one of the periods of the light-emitting control signal in the writing frame;
- wherein, total number of frames comprised in one display period is less than or equal to a skip frame limit;
- wherein the total number of frames is a sum of numbers of the writing frame and the multiple holding frames within one of the display periods, the skip frame limit is 2∧x, where x is number of bits corresponding to a register controlling number of skipped frames.
