Patent ID: 8189129

Claim:
A backlight system for producing a plurality of perspective views on LCD displays, for location behind an image-forming LCD having rows and columns and diagonal lines of pixel elements, comprising: a) a rectangular panel comprising a plurality of thin, linear light emitting sources, the light sources being slanted at a slope angle relative to sides of the panel in a direction such that the linear light emitting sources are parallel to diagonal lines of pixel elements; and b) a lenticular lens between the rectangular panel and the LCD, spaced in front of the light emitting sources, comprising a plurality of cylindrical lenslets on a surface of the lenticular lens, the cylindrical lenslets being slanted at a slope angle relative to sides of the lenticular lens in a direction such that the lenslets are parallel to the linear light emitting elements of the rectangular panel; such that the linear light emitting sources and the lenslets produce a series of small light emitting lines with one line for every N diagonal lines of pixel elements, where N is the number of perspective views to be produced.
