Abstract

The types of flaws susceptible to affect image quality in tiled displays are identified and psychophysical thresholds for their detectability are prescribed. Bright seams are not tolerable and completely dark seams have a threshold of 3. 5 arcsec. Tile luminosity variability threshold is less than 1 in some instances. Chromaticity variabilities must be kept well below 1 for one jnd discrimination in certain regions of the spectrum and vernier misalignments must be about 5 arcsec. Despite these stringent requirements tiling remains a viable way of making large displays.
