Segmented polymer stabilized and polymer free cholesteric texture liquid crystal displays and driving method for same

摘要

A display device (110) having first and second substrates (112) and (190) and a layer of a liquid crystal material having a periodic modulated structure, such as a PSCT or PFCT liquid crystal material disposed therebetween. The first substrate is divided into segment and non-segmented areas which are defined by a gap in the electrode materials disposed on the substrate. Similarly, the second substrate (190) is divided into common electrodes corresponding to the segmented and non- segmented areas on the first substrate.
