In this paper, Stencil Field Sequential Color (Stencil-FSC) is proposed, and we first utilize a "multi-color field" instead of a conventional "signal-color field" in the color sequence display. The Stencil-FSC method not only can suppress CBU effectively but also can be realized on LCDs by present LC techniques, such as OCB mode LC. Moreover, the method can achieve the a novel green display with ultra-low power consumption (5 Watt for 32 LCD-TV) and high contrast ratio (~6500:1). Consequently, the concept and the results of the paper may complete a next generation color filter less display with high image quality and ultra-low power consumption.
