Abstract
A pixel structure is disclosed which includes a first light-emitting device, a second light-emitting device, a common driving unit, a first driving transistor, a second driving transistor, a first switch unit operably coupled between the first driving transistor and the first light-emitting device, and a second switch unit operably coupled between the second driving transistor and the second light-emitting device. The second driving transistor has a channel width-to-length ratio smaller than that of the first driving transistor. The first switch unit and the second switch unit are configured to turn on time-divisionally. Also disclosed are a display device and a method for driving the pixel structure.
