    • Disclosed are various reverse-mode direct-view liquid crystal displays employing a liquid crystal having a characteristic wavelength in the non-visible spectrum, including reflective, transmissive and reflective-transmissive mode displays. In accordance with the principles disclosed, a direct-view liquid crystal display (LCD) includes a front substantially transparent substrate, a rear substrate, and a controllable cholesteric liquid crystal (CLC) disposed between the front and rear substrates and having a characteristic wavelength to reflect non-visible spectrum; the portions of the controllable CLC can selectively exhibit a planar state or a focal-conic state, the portions of the CLC in the planar state appearing dark, and the portions of the CLC in the focal-conic state appearing bright, to an observer of the LCD. The reflective, transmissive and reflective-transmissive mode displays are derived by further combinations with linear and/or circular polarizers, reflective mirrors and/or transmissive/reflective mirrors, and a source of visible light.
    • 公开了采用在不可见光谱中具有特征波长的液晶的各种反向模式直视液晶显示器,包括反射,透射和反射 - 透射模式显示。 根据所公开的原理,直视液晶显示器(LCD)包括前部基本上透明的基板,后部基板和设置在前部和后部基板之间的可控胆甾型液晶(CLC),并且具有特征波长 反映不可见光谱; 可控CLC的部分可以选择性地呈现平面状态或焦点锥形状态,平面状态下的CLC的部分看起来很暗,焦点锥形状态下的CLC的部分显现为明亮,观察者 LCD。 反射,透射和反射 - 透射模式显示是通过与线性和/或圆偏振器,反射镜和/或透射/反射镜以及可见光源的进一步组合得出的。
