Stencil-FSC method for color break-up suppression and low power consumption in field-sequential LCDs

Abstract

Field sequential color liquid crystal displays (FSC-LCDs) are still facing a serious artifact, colo break-up (CBU), which degrades image quality. Consequently, we propose the "Stencil-FSC" method, applying local color-backlight dimming technology to FSC-LCDs with a 240 Hz field rate which not only suppresses CBU efficiently but also enhances the contrast ratio of images in using ultralow average power consumption. The Stencil-FSC method was demonstrated on a 32-inch FSC-LCD and effectively suppressed CBU, resulting contrast ratio of more than 5,500:1, and average power of less than 45 Watt.
