Organic light emitting diode display device

Abstract:

An organic light emitting diode (OLED) display device is disclosed. In the OLED display device, a timing controller compares reference voltages output from driving integrated circuits (driving ICs). When a deviation occurs in the reference voltages, the timing controller compensates for the deviation of reference voltages. The OLED display device includes a display panel having reference voltage lines and a plurality of pixels, a data driving circuit having a plurality of driving ICs to generate reference voltages and to supply the reference voltages to the reference voltage lines of the display panel, and a timing controller for comparing reference voltages respectively output from the driving ICs to the display panel, thereby controlling the driving ICs such that the reference voltages respectively output from the driving ICs are equalized.
