ABSTRACT:
An electro-optical display device has a fluorescently activated plate disposed in front of a passive display in the line of sight of a viewer. The entire surface of the fluorescently activated plate is uncovered and is available for collecting ambient light to provide an image of increased intensity and allowing the device to be utilized in environments having low optical radiation levels. The fluorescently activated plate has exit windows thereon for retransmitting the light as controlled by the switchable regions of the passive display in a designated pattern to a viewer.
