Abstract
A cholesteric liquid crystal device has an optical response opposite to that of the Prior Art. The liquid crystal device takes advantage of a unique and unusual effect in cholesteric liquid crystals where pressure applied to the device with a pointed stylus, without applying a voltage, creates a transmissive texture as opposed to the planar texture of the Prior Art.
