Abstract
An organic light emitting diode display device includes a display panel including a plurality of pixels, and a panel driver configured to drive the display panel. Each pixel includes a driving transistor, a compensating transistor including first and second compensating sub-transistors coupled in series between a gate node and a drain of the driving transistor, a storage capacitor, and an organic light emitting diode. The panel driver calculates an average representative gray level of input image data in a plurality of frame periods, determines a voltage level of a node controlling voltage based on the average representative gray level, and provides the node controlling voltage to each of the plurality of pixels to control a voltage of a node between the first and second compensating sub-transistors.
