Abstract:
A method for correcting luminance and chromaticity variations caused by tile edge effects in tiled, flat-panel liquid crystal displays (LCDs), the steps comprising:a) providing at least two LCD tiles arranged adjacent one another with a seam therebetween, each of said tiles having an edge proximate said seam and an interior region with a plurality of pixels disposed therein, said pixels being adapted to modify transmitted light upon stimulation by respective pixel stimulation signals;b) mapping at least one region of said pixels in said LCD tiles, each of said pixels in said region having a similar effective T-V curve in an LCD tile;c) determining a transfer function for said mapped region to change one of said effective T-V curves to a predetermined, reference effective T-V curve; andd) applying an inverse of said transfer function to said pixel stimulation signals so that said pixels in said region appear to exhibit said predetermined, reference effective T-V curve.
