Abstract

Through a simulation study, the imaging performance of two types of multi-primary color liquid crystal displays (LCDs) with striped RGBCW (red, green, blue, cyan, and white) and RGBCY (red, green, blue, cyan, and yellow) pixel units is evaluated comparatively. Results show that color consistency and enhanced luminance can be achieved in image rendering with RGBCW rather than RGBCY pixels when the proposed color conversion algorithm is employed. Color measurement by spectrometry is conducted simultaneously to prove that with RGBCW pixels, the color imaging performance is almost as good as that with conventional RGB pixels; the luminance achieved with RGBCW pixel units is higher than that achieved with RGBCY pixel units.
