1. an organic light-emitting diode display system comprises:

  • A) display device that comprises a luminescence pixel array, each pixel has three or above a plurality of Organic Light Emitting Diodes of the light of the different colours that sends a color domain of regulation, and, at least one white OLED of the light of the color that is emitted in described color domain, the power efficiency of wherein said white OLED is greater than at least one the power efficiency in described a plurality of Organic Light Emitting Diode;

    B) for generation of the device of a controlled variable signal, described controlled variable signal means the size that the output of the light for display device that white OLED provides is made contributions, this control signal depends on that optional user sets, state or the ambient light illumination of display system, for changing power and the color relation between saturated;

    WithC) display driver, for receiving relative brightness that each pixel represent display device will produce and the standard colour picture signal of color, and produce the colour picture signal through conversion for the combination of described a plurality of Organic Light Emitting Diodes of driving display part and white OLED, described a plurality of Organic Light Emitting Diode sends to stipulate the light of the different colours of a color domain, and described white OLED sends the light of the color in color domain, when showing the colour picture signal of process conversion, display driver is in response to described control signal, control the light quantity that described white OLED produces, thereby can improve the power efficiency of display device and/or reduce the speed of display device hydraulic performance decline.
