Classification: CPC G  H | IPC G

Claim 20:
21. A display device comprising a plurality of sub-pixels, each sub-pixel comprising:
a light emitting element;
a first pixel driver configured to supply a control current to a first node according to a pulse-width modulation (PWM) data voltage received from a first data line;
a second pixel driver configured to generate a driving current according to a pulse-amplitude modulation (PAM) data voltage received from a second other data line; and
a third pixel driver configured to adjust a period during which the driving current is supplied to the light emitting element according to a voltage of the first node,
wherein a peak current value of the driving current when the light-emitting element emits light for image data having a gray level between a first level and a second level is smaller than a peak current value of the driving current when the light-emitting element emits light for image data having a gray level region between the second level and a third level higher than the first level.
