    • An image display is disclosed comprising an image display device 60 with a light emitting surface, the light emitting surface having an array of picture elements; a light guide 20 formed from a plurality of light transmission guides 80 with the input to each light transmission guide being provided by a sub-array of a plurality of picture elements from the light emitting surface of the image display device and luminance correction means to assign a colour component value and a dither fraction value to each sub-array of a plurality of picture elements on the light emitting surface of the image display device. Assigning a colour component value and a dither fraction value to each sub-array of picture elements on the image display device which provide the inputs to light transmission guides of the light guide can correct for differences which could be related to individual image display device or light guide non-uniformity at the individual pixel level or to correct the macroscope differences between image displays when used with multiple image display devices. The position or grey level difference of dithered picture elements in the sub-array may be selected dependent upon the position of the sub-array in the image display to reduce the effects of relative misalignment of the image display device and light guide due to thermal expansion or contraction.
