Abstract
An organic light emitting diode (OLED) display includes pixel rows, and a panel driver configured to drive the display panel. The panel driver includes a determining circuit configured to select one pixel row from the plurality of pixel rows, to determine load data based on input image data for the one pixel row, and to determine target mobility data corresponding to the load data, a sensing circuit configured to generate mobility sensing data corresponding to mobility values of driving transistors of a plurality of pixels included in the one pixel row by performing a mobility sensing operation on the one pixel row, and a current control circuit configured to compare the mobility sensing data and the target mobility data to generate a result, and to adjust a panel current flowing through the display panel according to the result.
