Abstract
(EN)
A display panel including a plurality of pixels is provided. The display panel includes: a plurality of light emitting elements configured to constitute each pixel of the plurality of pixels; and a plurality of pixel circuits respectively corresponding to the plurality of light emitting elements and configured to drive the plurality of light emitting elements, wherein the plurality of pixel circuits includes a first pixel circuit for pulse width modulation (PWM)-driving a first light emitting element among the plurality of light emitting elements and a second pixel circuit for pulse amplitude modulation (PAM)-driving a second light emitting element among the plurality of light emitting elements.
