A display device comprises a display panel, a drive circuit configured to drive the display panel, a timing controller configured to control the drive circuit, and a power supply configured to output a supply voltage to the display panel. The timing controller is configured to output a vertical synchronization signal having an image display period and a blanking interval. The power supply is configured to vary a level of the supply voltage during the blanking interval of the vertical synchronization signal.

Display device and method of driving the same

Disclosed are an organic light emitting display and a method of driving the same. A charging circuit supplies charging voltages to organic light emitting diodes included in the plurality of subpixels, wherein a different charging voltage is supplied to at least one of the organic light emitting diodes. The data driver supplies data signals to data lines of the plurality of subpixels.

Organic light emitting display (OLED) and method of driving the same

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.
