Abstract: A display panel includes a plurality of pixels arranged in a matrix, the plurality of pixels respectively including a plurality of sub pixels. The plurality of sub pixels respectively includes a light emitting element, and a PWM pixel circuit configured to control a light emitting duration of the light emitting element, based on a pulse width modulation (PWM) data voltage and a sweep voltage. A plurality of PWM pixel circuits included in the display panel are driven, for each of row lines of the plurality of pixels, in an order of a data setting period for setting the PWM data voltage and then a light emitting period in which the light emitting element emits light during a duration corresponding to the set PWM data voltage according to a change of the sweep voltage.
