ABSTRACT:
An OLED display system includes a display device having an array of light emitting pixels, each pixel having a plurality of OLEDs for emitting different colors of light specifying a gamut and at least one additional OLED for emitting a color of light within the gamut, wherein the power efficiency of the additional OLED is higher than the power efficiency of at least one of the plurality of OLEDs; means for generating a control signal indicating an amount of contribution to the light output of the display provided by the additional OLEDs; and a display driver for receiving a standard color image signal representing relative luminance and color to be produced for each pixel of the display and generating a converted color image signal for driving the OLEDs in the display, the display driver being responsive to the control signal for controlling an amount of light produced by the additional OLEDs such that the power efficiency of the display may be increased and/or the rate of degradation of the display device may be decreased.
