Abstract: 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.

Abstract: An organic light-emitting diode (OLED) display, display system including the same and method of driving the same are disclosed. In one aspect, the OLED display includes a display panel including a plurality of pixels arranged on a front surface of the panel and a plurality of temperature sensors arranged on a rear surface of the panel. The temperature sensors are configured to output a plurality of sensed temperature signals. The OLED display further includes a timing controller including a memory configured to store a temperature model look-up table (LUT). The timing controller is configured to convert the sensed temperature signals using the temperature model LUT, calculate a compensation coefficient based on the converted temperature signals and compensate image data based on the calculated compensation coefficient. The temperature model LUT is configured to nonlinearly map the sensed temperature signals to the converted temperature signals.
