Display device and electronic device including the same

Abstract

A display device includes a display panel including a pixel, and a panel driver providing a reference voltage and a data voltage to the pixel. The pixel emits a light corresponding to a difference between the reference voltage and the data voltage. The panel driver includes a power management circuit generating an analog power supply voltage, and providing the analog power supply voltage to a data driver. A driving mode of the display device includes a first mode emitting the light at a first luminance for a first gray level, and a second mode emitting the light at a second luminance higher than the first luminance for the first gray level. The analog power supply voltage has a first analog power supply voltage level in the first mode, and a second analog power supply voltage level higher than the first analog power supply voltage level in the second mode.
