摘要： A display device includes PAM data lines receiving PAM and PWM data voltages, and sub-pixels connected to the PAM and PWM data lines. A sub-pixel includes a light emitting element, a first pixel driver to supply a control current according to one of the PAM data voltages to a node, a second pixel driver to generate a driving current according to one of the PWM data voltages, and a third pixel driver to adjust a period during which the driving current is supplied to the light emitting element according to a voltage of the node. A peak current value of the driving current when the sub-pixel emits a light corresponding to a low gray level region is smaller than a peak current value of the driving current when the sub-pixel emits a light corresponding to a high gray level region higher than the low gray level region.
