胆甾型和向列型液晶电光电池被描述为既充当紫外线快门又充当可调谐荧光发射器（快门电池）的功能。蓝-绿、蓝-红或绿-红的两色显示是在带有外部被动荧光元件的快门单元的双层结构中实现的。通过电开关快门单元，这两种颜色对的对比度约为5。测量了几种荧光客体材料的显示特性，并讨论了它们对各种系统参数的依赖关系。多色荧光显示器是由快门单元和被动元件组成的三层结构制成的。
Cholesteric and nematic liquid‐crystal electro‐optic cells are described which function as both UV shutters and as tunable fluorescent emitters ( shutter cells ). Two‐color displays of blue‐green, blue‐red, or green‐red are achieved in the double‐layered structure of the shutter cell with an external passive fluorescent element. Contrast ratios of about 5 in these two‐color pairs are achievable by electrically switching the shutter cell. Display characteristics for several fluorescent guest materials are measured and their dependence on various system parameters is discussed. Multicolor fluorescent displays are made by using a triple‐layered structure of shutter cells and passive elements.
