Abstract

A high brightness presentation display system includes: a transparent display panel having a viewing side and a non-viewing side, furcated row electrode array, furcated column electrode array defining matrix crosspoints and an electro-responsive display producing medium at said matrix crosspoints. Row electrode drive circuitry is connected to selectively drive electrodes in the row electrode array and column electrode drive circuitry is connected to selectively drive electrodes in the column electrode array such that conjoint voltages on selected row and column electrodes operate the display. The furcated electrode spacing and interelectrode spacings are such as to enhance discrimination, and the multiple sub-pixels due to the furcations of electrodes enhance brightness. Optical sensor positioned on the non-viewing side for viewing through the transparent display panel at a predetermined position from the viewing side of the transparent display panel is activated by a remote source producing a control beam of optical energy through the transparent display panel. Optionally, electrically generated icons displayed on the panel can be used to locate the sensors. Color displays and displays having high visibility in sunlight are disclosed.
