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.

Abstract: A data compensator includes first logic, second logic, third logic, fourth logic, and fifth logic. The first logic calculates block compensation coefficients for blocks in a first frame based on first pixel data of the first frame. The second logic generates first gamma applied pixel data based on the first pixel data of the first frame and to generate second gamma applied pixel data based on the first gamma applied pixel data and second pixel data of a second frame adjacent the first frame. The third logic selects a number of the block compensation coefficients based on a pixel coordinate. The fourth logic generates a pixel compensation coefficient corresponding to the second pixel data by interpolating the selected block compensation coefficients based on the pixel coordinate. The fifth logic generates output pixel data based on the second gamma applied pixel data and the pixel compensation coefficient.
