Wide color-gamut improvement of LCM using multi-phosphor white LED and modified rich color method

This paper presents an improved wide color-gamut technique for liquid crystal modules (LCM) with multiphosphor white (MPW) light emitting diodes (LED) and an modified rich color image processing method. The MPW LED improves 13% of the display color gamut in comparison with standard white LED under the assumption of equal power consumption and brightness. Via many simulation results, the pixel-level rich color method is shown to obtain a superior image data by giving about 45% saturation enhancement without hue distortion. The performance and merit of the proposed technique are exemplified by conducting several experimental results on a 2.8-inch thin-film-transistor (TFT) LCM.
