Abstract
A unitarily white touch display comprises: a cover lens, a viewing area, from an upper surface to a lower surface of the cover lens, formed in the middle of the cover lens; a touch module disposed under the cover lens to provide touch functions; a light valve module disposed under the touch module and filled with a polymer dispersed liquid crystal layer; a microstructure optical film disposed under the light valve module, and a second surface of the microstructure optical film composed of a plurality of micro-prisms. When incident light enters the touch display, the incident light is scattered by the polymer liquid crystal module, and part of the incident light is reflected by the microstructure optical film, re-transmitted and scattered through the polymer liquid crystal module, so that a user can observe foggy white at the viewing area of the touch display.
