Abstract
A bistable liquid crystal display device can be erased by the application of a mechanical pressure P at a section 20 of the display. The pressure induces a flow of the liquid crystal (5) material into an expansion chamber (22). The induced flow causes a transition from the non-reflecting to the reflecting state, thus eliminating the necessity of high voltage erasing voltages.
