Abstract

We proposed the "180Hz Stencil-FSC" method to suppress color break-up (CB U) in field-sequential color (FSC) LCDs. Applying local color-backlight-dimming technology to FSC-LCDs, a "green-based multi-color" field-image was generated to show most image luminance at the first field and effectively suppressed CBU when compared to field-rate increasing methods. In addition, to further implement hardware, the number of backlight divisions of 32x24 was optimized while considering CBU suppression and image fidelity. Using optimized hardware parameters, the CBU phenomenon was suppressed by 50% of traditional RGB driving in simulation and was demonstrated on a 120Hz 46-inch MVA LCD-TV.
