Abstract:
A tiled, flat-panel display comprising an nÃ—m array of pixels and having visually imperceptible seams, comprising:a) four display tiles, each comprising approximately an n/2Ã—m/2 sub-array of pixels defining essentially identical viewing areas, the variables n and m comprising one pair from the set: 640Ã—480 (VGA); 800Ã—600 (SVGA); 1024Ã—768 (XGA); 1152Ã—864; and 1280Ã—1024, the pixels of said sub-array of pixels comprising a pixel cell gap and substantially uniform pixel pitch, said pixel cell gaps in pixels proximate said seam regions being substantially equal to said pixel cell gaps in pixels disposed in an interior region of said sub-arrays of pixels each of said pixels of said sub-arrays having an active, central area surrounded by an inactive, dark area having a predetermined width; b) seam regions disposed between adjoining edges of said four display tiles for maintaining said substantially uniform pixel pitch across said seam regions, said seam regions comprising thin, perimeter seals at adjoining edges of each of said four display tiles, said thin perimeter seals having a width no greater than said predetermined width of said inactive, dark area, and said thin perimeter seals in said dark regions comprising dispense pads and dam structures formed in a color filter (CF) layer of each of said four display tiles to control the spread of a sealing material forming said thin, perimeter seals; c) polarizing means for polarizing light disposed adjacent to and substantially parallel to a rear surface of said four tiles; and d) support means disposed adjacent to and substantially co-planar with said polarizing means for polarizing light, said support means supporting said four display tiles.
