What is Ch-LCD?

Ch-LCD stands for Cholesteric Liquid Crystal Display. The other term that is used is "bi-stable" or "no power" LCD. It means that the crystals have to positions in which they "rest". Once the image is downloaded on the screen, it will stay there even if there is no power applied.

Cholesteric liquid crystal display (Ch-LCD)are lightweight, low power, sunlight readable displays. In addition, they can serve a dual function as pen-input device switch no additional hardware. Because of the unique properties of this technology, Ch-LCDs can be made with plastic substrates thus making the displayed extremely lightweight, compact and unbreakable.
