ORGANIC LIGHT-EMITTING DIODE DISPLAY DEVICE AND METHOD OF OPERATING THE SAME

摘要

An organic light-emitting diode (OLED) display and a method of operating the same are disclosed. In one aspect, the display includes a plurality of pixels each including a pixel circuit and produces grayscale values by adjusting an emission duty based at least in part on image data. The method comprises calculating a voltage drop of a power supply voltage at each of the pixel circuits based at least in part on the image data and extracting a luminance decrement corresponding to the voltage drop for each pixel circuit based at least in part on a voltage-luminance characteristic of the pixels. The method also comprises increasing the emission duty for each pixel based at least in part on the luminance decrement, and driving the pixels based at least in part on the increased emission duty.
