Abstract:
A large flat panel display comprising:a) a plurality of tile display modules, each tile display module comprising a field emission display module having a plurality of pixels arranged in a matrix having uniformly periodic interpixel spacing, and each tile display module having electrical interconnection means for addressing said pixels so that each pixel may be selectively controlled through said electrical interconnection means, and pads for interconnecting with said electrical interconnection means, each of said tile display modules further comprising a ledge formed on the edge of at least one layer of said tile display module between the layers thereof, in which said ledge is inset into one of said layers, the edge of said layers being coterminous; andb) a back plate for supporting and interconnecting said tile display modules, having at least one layer of interconnection lines for connection to said electrical interconnection means of a plurality of said tile display modules, said interconnection lines having pads for electrical connection thereto;said tile display modules being mounted upon said back plate, with said pads of said tile display modules being electrically connected to said pads of said interconnection lines of said back plate, aligning said tile display modules thereon, and located so that the interpixel spacing between two of said adjacent pixels on two adjacent tile display modules maintains the uniform periodicity of interpixel spacing between adjacent pixels within said tile display modules, said tile display modules comprising layers bonded together by an adhesive and said pixels of said large flat panel tile display being addressed via said interconnection means of said back plate as if said large flat tile display, comprising a plurality of tile display modules, were a single monolithic large display.
