Abstract: An organic light-emitting diode (OLED) display device including: a display panel including a plurality of pixels and light emission control transistors; a data driver configured to supply data signals to the pixels through data lines; a scan driver configured to supply scan signals to the pixels through scan lines; a temperature detector; a first power supply configured to supply drive voltages to the pixels; a light emission controller configured to set the light emission control transistors to a turned-on state; and a timing controller configured to determine a drive mode of the display panel, wherein the scan driver and the data driver supply scan signals and data signals to the pixels at a first frame frequency in a first drive mode, and to supply scan signals and data signals to the pixels at a second frame frequency, lower than the first frame frequency, in a second drive mode.
