TILED DISPLAY WITH FILTER FOR UNIFORM PIXEL BRIGHTNESS

摘要

An image display comprises an image display device having an array of electrically driven picture elements (60) viewable at a viewing surface (90); and luminance correction means (110) arranged with respect to the image display device so as to apply a spatial luminance filter (122, 124) to the output of the image display device, the spatial luminance filter attenuating the light output by each picture element of the image display device in substantially inverse relation to the luminance response characteristics of the picture element so that each picture element exhibits substantially the same luminance for a given input electrical driving signal.
