Abstract

Field-sequential-color liquid crystal displays (FSC LCDs) exhibit a similar to 3 x higher optical efficiency and 3 x higher resolution, but the color breakup (CBU) degrades the image quality and limits the practical applications. In this paper, we propose a method to reduce CBU by using five-primary LEDs instead of three. Without increasing the sub-frame rate as three-primary LCDs, we can suppress the CBU by utilizing proper color sequence and weighting ratios. The color gamut achieves 140% NTSC and the white brightness increases by more than 13%, as compared to the three-primary LCDs.
