Abstract
A power control device includes a temperature sensing unit sensing a temperature of a display panel and outputting a temperature sensing value, a timing controller generating a power control signal, and a power management integrated circuit (PMIC) adjusting a voltage level of high potential driving power to be applied to the display panel on a basis of the power control signal. When a voltage level of VDDEL is adjusted using a S-wire interface scheme, VDDEL is adjusted when the power control signal satisfies a preset condition, whereby an influence of noise is excluded and a stable output may be obtained.
