| titleOfInvention | Backlight Unit With Reduced Color Separation Including A Polarizing Turning Film |
| abstract | A backlight unit (110) contains a light source (201,202,203), a light guiding plate (10'), and a turning film (20) having a light entry and a light exit surface comprising first prismatic structures on the exit surface, wherein n(a) the first prismatic structures on the turning film (20) are characterized by a far base angle (β 1 ) and a near base angle (β 2 ); n(b) the light source (201,202,203) comprising an array of individual sources of differing colors; n(c) the light guiding plate (10') being located to provide light from each individual light source (201,202,203) having a different principle angle to the turning film (20) for each color; and n nthe light guiding plate (10') being arranged in a manner relative to the light source (201,202,203) and the turning film (20) and its first prismatic structures and base angles so as to reduce the amount of color separation at the exit surface of the turning film (20) compared to the same device using a single light source. |
