Abstract
A liquid crystal device that is flexible and includes a cholesteric liquid crystal material erased by flexing. Totally free of electronics and electrically conductive electrodes, the liquid crystal device takes advantage of a reverse mode effect observed in cholesteric liquid crystals whereby pressure applied to the device changes a reflective texture to a transmissive texture to create an image. The image is erased and the device reinitialized by flexing to create reflective texture surroundings.
