Ultrathin optical panel and a method of making an ultrathin optical panel

Abstract

An ultrathin optical panel, and a method of producing an ultrathin optical panel, are disclosed, including stacking a plurality of glass sheets, which sheets may be coated with a transparent cladding substance or may be uncoated, fastening together the plurality of stacked coated glass sheets using an epoxy or ultraviolet adhesive, applying uniform pressure to the stack, curing the stack, sawing the stack to form an inlet face on a side of the stack and an outlet face on an opposed side of the stack, bonding a coupler to the inlet face of the stack, and fastening the stack, having the coupler bonded thereto, within a rectangular housing having an open front which is aligned with the outlet face, the rectangular housing having therein a light generator which is optically aligned with the coupler. The light generator is preferably placed parallel to and proximate with the inlet face, thereby allowing for a reduction in the depth of the housing.

[0003] Statement Regarding Federally Sponsored Research and Development [0004] This invention was made with Government support under Contract No. DE-AC02-98CH10886 with the US Department of Energy. The government has certain rights in this invention. technical field [0005] The present invention relates to a flat optical display, more precisely, to an ultra-thin display panel and a method for manufacturing the ultra-thin display panel. Background technique [0006] Optical screens typically use cathode ray tubes (CRTs) to project images onto the screen. A standard screen has a 4:3 aspect ratio and a vertical resolution of 525 lines. The beam of electrons is scanned horizontally and vertically across the screen, creating a large number of pixels that are combined to form ...
