Abstract

A two dimensional display panel produces a time variable image composed of light emitting pixels. The pixels are generated by a light emitting phosphor distributed within the panel, the pixels radiate light in response to being excited by charging and triggering energy beams. The energy beams are relatively invisible and may be generated by lasers or solid state diode energy sources. Wave guides within the panel direct the energy beams to the pixels. The wave guides may be composed of fiber optic threads and the display panel comprised of a fabric of woven fiber optic threads wherein pixels are produced at intersections of the woven fiber optic threads. The brightness of the pixels are controlled by regulating the duty cycle of a column driver relative to the duty cycle of a row driver. The display energy beams are driven to facilitate interface with a pen-like pointing device. In one embodiment the pen receives relatively invisible energy beams and in another embodiment the pen receives visible pixel light. In another embodiment, the invention has redundant energy beam sources and driving circuitry in order improve display system reliability. In another embodiment the wave guides have corresponding polarizers for producing alternating orthogonally polarized pixels of light for use in displaying stereoscopic three dimensional images from the two dimensional display panel. In another embodiment the wave guides are formed to allow intersecting energy beams from the arrays to enter the display at a single edge wherein the wave guides direct the energy beams to appropriate intersections, thereby freeing the remaining edges of the display for uses other than displayed image generation.
