| 20110025593 | BACKLIGHT UNIT AND DISPLAY APPARATUS INCLUDING THE SAME - A backlight unit includes a plurality of light sources emitting light in a direct direction with a predetermined orientation angle, and a light guide panel having a light incident section and a light emitting section. The light incident section has a first surface to receive light emitted from one or more of the light sources in the first direction and the light emitting section is to emit light received from the light incident section in a second direction. In addition, a height of an elevated structure, extending from an upper surface of the light incident section to an upper surface of the light emitting section, is greater than or substantially equal to a height of a distal end of the light emitting section. | 02-03-2011 |
| 20110026239 | BACKLIGHT UNIT AND DISPLAY APPARATUS INCLUDING THE SAME - A back-light unit including a plurality of substrates, a plurality of light sources respectively disposed on the plurality of substrates and configured to emit light, and N (N≧2) light guide panels respectively disposed adjacent to the plurality of light sources, a corresponding light guide panel including a light incidence part having a light incidence surface for receiving light emitted from a corresponding light source, and a light emission part for emitting the received incident light. Further, the corresponding light guide panel includes protruding surface patterns protruding from an upper surface the light emission part. | 02-03-2011 |
| 20110050557 | BACKLIGHT UNIT AND DISPLAY APPARATUS INCLUDING THE SAME - A backlight unit may be provided that includes a substrate, light sources, and a light guide plate. The light sources are arrayed on the substrate, and emit light with a predetermined orientation angle with respect to a first direction, and include first through third light sources adjacent to each other. The light guide plate may include a light incident part having a light incident surface to which streaks of light respectively emitted from the light sources are laterally incident, and a light emitting part emitting the incident streaks of light upward and having a side adjacent and connected to the light incident part. A first distance between the first light source and the second light source is less than a second distance between the second light source and third light source. | 03-03-2011 |

| 20100302805 | LED BACK-LIGHT UNIT AND DISPLAY DEVICE - A back-light unit including a plurality of substrates, a plurality of light sources respectively disposed on the plurality of substrates and configured to emit light, and N (N ≧2) light guide plates respectively disposed adjacent to the plurality of light sources, each light guide plate including a light incidence part having a light incidence surface for receiving light emitted in a first direction from a corresponding light source, and a light emission part for emitting the received incident light in a second direction different than the first direction. Further, at least one of the light guide plates includes light-extracting surface patterns disposed on the light emission part, and the light-extracting surface patterns comprise a first region of light-extracting surface patterns having a higher pattern-density than a second region of light-extracting surface patterns next to the first region. | 12-02-2010 |
