1. Organic Light Emitting Diode display system comprises:

  • A) display device that comprises a luminescence pixel array, each pixel has a plurality of Organic Light Emitting Diodes of the light of the different colours in color domain of the regulation sent, and at least one the additional Organic Light Emitting Diode of light that is used for being emitted in a kind of color of said color domain, the power efficiency of wherein said additional Organic Light Emitting Diode is greater than at least one the power efficiency in a plurality of Organic Light Emitting Diodes;

    B) be used to produce the device of a power signal, the size that output is made contributions for display light that the Organic Light Emitting Diode that said power signal is represented to add provides;

    With,C) display driver, being used to receive representative will be to the relative brightness of each display picture element generation and the standard colour picture signal of color, and produce the colour picture signal through conversion of the Organic Light Emitting Diode that is used for driving display, display driver is in response to said control signal, the light quantity that the additional Organic Light Emitting Diode of control produces is with power efficiency that improves display and/or the speed that reduces the decline of display device performance.
