Abstract :
In this paper, a new OLED(Organic Light Emitting Diode) color display method is introduced. Unlike the most commonly used technique-RGB-polymer emitters, there are four colors. That is in addition to red, green and blue (RGB) tri-color light-emitting materials, there is a white light-emitting materials. First the impact of the brightness stability and life factors of various materials are analyzed, than its drive circuit is discussed in detail. Through the control of the current for each RGB, improved its color and life context, achieved the color balance of high-resolution OLED panels, and reduced the total power consumption.
