Description
Summary:In this paper, design principle for the optimization of the full-color display is suggested to show nearest white light by mixing high radiance R,G,B LEDs with appropriate proportional indices. By counting these three colors to be additive mixing and producing white light color contrasted to negative mixing, each number of LEDs is theoretically deduced and designed with several shapes of chips for the full-color displays. Finally theoretical predictions are compared with the measured data for different type of display designs.
