Abstract:
A monolithic, AMLCD display being a robust laminate and having controlled contrast, luminance and chromaticity across a wide view angle range, comprising:a) an AMLCD flat-panel assembly having a front, viewing face and a rear face, said front viewing face being substantially rectangular and having a diagonal measurement of at least approximately 19 inches; b) backlighting means comprising an array of tubular lamps disposed proximate and directly behind said rear face of said AMLCD flat-panel assembly for providing illumination thereto; c) light collimating means proximate said rear face and said backlighting means; and d) means for decollimating light proximate said front, viewing face of said AMLCD flat-panel for decollimating light therefrom, said means for decollimating light having a different directivities (i.e., decollimation efficiencies) in planes substantially parallel to a long said and a short side respectively of said substantially rectangular viewing face; whereby said AMLCD flat-panel assembly achieves a viewing angle of more than 70 degrees off an axis perpendicular said viewing face and in a horizontal plane substantially parallel to a longer side of said of said substantially rectangular viewing face.
