  • Patent number: 4563617
    Abstract: A bright, economical, flat panel television/display is fabricated by laser welding incandescent metal particles together to form light emitting micro-beads, the ends of which are simultaneously welded to driving electrodes. The small physical mass and dimensions of each bead permit it to be fired to an incandescent state at high rates, becoming a controllable, bright, point source of light suitable as a picture element to create moving images. The beads are suspended between a heat resistant substrate and faceplate, both of which contain depressions proximate to each bead to provide thermal spacing and optical and thermal reflectivity to direct visible light out of the panel, and heat back to the bead, conserving power. Color filters provide full color image display in a system operating at approximately five volts, and which can be built to any size and shape. Three dimensional display capability is inherent when a plurality of transparent display panels are laminated.
