Abstract
An organic light emitting diode (OLED) display device includes a plurality of OLED pixels, a gate driver, a source driver, and a voltage controller. Each of the OLED pixels includes a current control switch and an OLED. A first end of the current control switch is coupled to a first voltage source. A first end of the OLED is coupled to a second end of the current control switch, and a second end of the OLED is coupled to a second voltage source. The gate driver is configured to output scan signals to sequentially turn on the plurality of OLED pixels. The source driver is configured to output display voltages to the plurality of OLED pixels. The voltage controller is configured to adjust a voltage difference between the first voltage source and the second voltage source according to a maximum grey level value of display data of a frame.
