Abstract:
A method of producing a seamless tiled display image from multiple overlapping discrete images displayed by multiple displays, comprising:measuring a luminance profile of each of the multiple displays used in producing the seamless tiled display image; computing a desired luminance profile of each of the multiple displays producing the seamless tiled display image, wherein the desired luminance profile includes a fall-off luminance profile computed using a mathematical function for outside a center region of the seamless tiled display image for each display; and determining a spatial gradient profile of each of the multiple displays based on the measured luminance profile and the computed desired luminance profile of each of the multiple displays, respectively, to modulate a light to produce a seamless tiled display image from the multiple displays.
