Abstract: A display panel includes a first display region and a second display region; the first display region includes first sub-pixels provided with first pixel density; and the second display region includes second sub-pixels provided with second pixel density, where the first pixel density is lower than the second pixel density. During one frame of picture display, a light-emitting phase of the first sub-pixel includes a first light-emitting period, and a light-emitting phase of the second sub-pixel includes a second light-emitting period; for same target brightness, the first sub-pixel emits light with first light-emitting brightness in the first light-emitting period, and the second sub-pixel emits light with second light-emitting brightness in the second light-emitting period, where the first light-emitting brightness is higher than the second light-emitting brightness; and the first light-emitting period is shorter than the second light-emitting period.
