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.

此篇论文中提出利用多色影像於单一色场的新色序法概念，此想法不但跳脱以往只使用单色场影像之基本架构，并可大幅改善色分离现象，使场色序液晶显示器之影像画质可以被观赏者接受，且操作频率为现行液晶可达到的反应时间内(40 Hz/field)；另外，此技术亦可同时达成低功率消耗(5 Watt for 32 LCD-TV)及高动态对比度(~6， 500：1)之新型绿色节能高画质显示技术，因而此论文的构想与成果将有可能使未来液晶电视转成免彩色滤光片且具高画质、低耗能之显示架构。
