DUAL DISPLAY APPARATUS

摘要

A bidirectional LCD(Liquid Crystal Display) is provided to display an image bidirectionally by a display panel and a light unit, thereby reducing the number of light emitting diodes. A light unit supplies an inner light beam. A display panel includes transmission pixels and reflection pixels, displays the first image by the inner light beam transmitted at the transmission pixels, and displays the second image by the inner light beam reflected by the reflection pixels. A position recognition substrate has a position recognition sensor for recognizing the position by the inner light beam. The position recognition sensor includes a sensor transistor member(SEN_T) for receiving the light beam and generating an optical current. A charging member(Cst) stores a light current as a charge type. A switching transistor(SW_T) selectively emits the charge of the charge member. The light unit is arranged at the upper portion of the display panel. The position recognition substrate is arranged at the upper portion of the light unit.
