摘要

In this research work, an innovative pixel architecture RGBW, consisting of red (R), green (G), blue (B), and white (W) LEDs, is designed and implemented for color generation. Energy consumption of new pixel architecture consisting of RGBW LEDs is compared to standard architecture consisting of RGB LEDs. Human perception experiments are conducted to study the differences in perception between the two architectures when the same colors are generated using RGBW vs. RGB. Measurements of power for a 32inch x 16inch LED display has proved up to 18% power savings for low saturated colors, up to 8% for high saturated colors and up to 30% for white color using RGBW as a substitute. In addition, experiments on human perception have shown that majority of test subjects could not differentiate between most colors displayed using RGB and RGBW showing that RGBW is an excellent substitute for RGB. Statistic analysis has shown that 90% of test subjects found the colors to be the same, whereas 86% test subjects found the intensities of the colors to be the same.
