发明名称 ORGANIC LIGHT EMITTING DISPLAY
摘要 An organic light emitting display includes a pixel unit, a data driver, a power supply unit and a controller. The pixel unit includes a plurality of pixels, and is divided into a plurality of division areas. The data driver outputs, to the pixel unit, a data signal corresponding to image data. The power supply unit applies power voltages to the respective division areas in the pixel unit. The controller controls the power supply unit to apply each power voltage having a voltage level corresponding to the maximum gray scale level of the image data allocated to each division area, and corrects the image data so as to compensate for differences in luminance between the division areas according to different voltage levels of the power voltages.
