20120092592 | BACKLIGHT UNIT AND LIQUID CRYSTAL DISPLAY DEVICE HAVING THE SAME - A backlight unit has a light source area. The width of the light source area in a first direction is shorter than the width of a liquid crystal panel in the first direction. A plurality of LED modules ( | 04-19-2012 |
20120113355 | LIQUID CRYSTAL DISPLAY DEVICE - A light source section provided in a backlight unit has a smaller width in a direction perpendicular to a length direction of the light source section than a width in the same direction of the liquid crystal panel. A plurality of LED modules are arranged along the length direction of the light source section. The LED modules are respectively assigned to areas of the liquid crystal panel, which are extended in the width direction of the light source section. Lenses are respectively disposed over the LED modules and expand light toward the areas. A control device controls each of the plurality of light sources separately or each of groups into which the plurality of light sources are divided, separately. Accordingly, it is possible to improve a contrast of a display screen, while reducing the number of light sources. | 05-10-2012 |
