| 20100097825 | Light Guide Plate - A light guide plate has a light emitting surface, a bottom surface opposite to the light emitting surface, a light incident surface, and a side surface opposite to the light incident surface. The light incident and side surfaces are connected between the light emitting and bottom surfaces. Light guide units are disposed on the bottom surface. Each light guide unit extends along a first direction. The first direction is towards the side surface from the light incident surface. Each light guide unit includes geometric patterns and stripe patterns for cascading the geometric patterns. Micro structures are disposed in the geometric patterns and the stripe patterns. Width of the geometric pattern along a second direction perpendicular to the first direction is greater than that of the stripe pattern. The light guide plate improves uniformity of a plane light source emitting from the light emitting surface of the light guide plate. | 04-22-2010 |
