Flat panel display with full color capability

摘要

A color capability flat panel display comprised of the combination of two semi-independent linear displays. One of the displays is an active light emitting linear display and the other display is a passive light modulating linear display wherein both of the linear displays are orthogonally aligned on opposite sides of an optically thin dielectric spacer. The active display may be an electroluminescent panel comprised of opaque linear electrodes on the back side and a common transparent electrode that is contiguous with the dielectric spacer on the front side. A plurality of vertical color electroluminescent phosphor stripes are sandwiched between the horizontal electrodes and the transparent electrode. The passive display is comprised of electronic birefringent electro-optical material having linear interdigital surface electrodes thereon sandwiched between two orthogonal dichroic polarizers.
