Patent ID: 8462292

Claim:
A method of displaying images in response to a video signal, comprising the steps of: providing a light emitting assembly including a plurality of optically transmissive substrates, films, or sheets, wherein each of the substrates, films, or sheets has at least one pattern of optical elements at the substrates, films, or sheets; and a plurality of light sources, each light source being configured to emit light into at least one area of the substrates, films, or sheets; configuring the light emitting assembly to emit light through the patterns of optical elements and to produce a predetermined luminance profile of the light emitting assembly; configuring a liquid crystal panel to be illuminated by the light emitting assembly; receiving an input video signal; and dimming or boosting at least one of the plurality of light sources in response to the input video signal while operating the liquid crystal panel as a light valve, wherein an end portion of at least one of the substrates, films, or sheets overlaps another end portion of an adjacent substrate, film, or sheet, the optical elements are substantially smaller than the length and width of the substrates, films, or sheets, and the optical elements of the respective patterns at the adjacent substrates, films, or sheets adjacent a seam between the overlapping end portions have shapes that substantially match one another to form a substantially seamless transition with minimal discontinuities in the optical element shapes at the seam to make the seam less visible.
