Abstract:
A method for producing a tiled, flat-panel LCD display having substantially uniform luminance and chromaticity and having visually imperceptible seams, the steps comprising:a) arranging a plurality of individual display tiles with seams therebetween, each of said tiles comprising an array of pixels, said pixels comprising sub-pixels for transmitting a predetermined primary color upon application of a sub-pixel stimulation signal;b) adjusting luminance and chromaticity of said sub-pixels located at interior regions of said individual tiles to a first, predetermined level;c) adjusting luminance and chromaticity of said sub-pixels located proximate intersections of said seams;d) adjusting luminance and chromaticity of said sub-pixels located proximate said seams between said individual tiles to a second, predetermined level; ande) blending said first and said second predetermined levels whereby differences in luminance and chromaticity between said interior region and said seams are reduced below a predetermined perceptual threshold.
