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, wherein said variables n and m comprise 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 substantially uniform pixel pitch, each of said pixels of said sub-arrays having an active, central area surrounded by an inactive, dark area having a predetermined width, said pixels each comprising a pixel cell gap; and 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, said thin perimeter seals being formed using color filter dispense pads for controlling the central location and profile of seal material as it is dispensed, and wherein said pixel cell gaps in pixels proximate said seam regions are substantially equal to said pixel dell gaps in pixels disposed in an interior region of said sub-arrays of pixels.
