| 20110188001 | PROJECTOR USING LEDS AS LIGHT SOURCES - A projector is provided, which includes a red substrate, a green substrate, a blue substrate, an X-cube, an electronic control element, a light guide element, a light valve element, and a projection lens. The red substrate, the green substrate, and the blue substrate respectively illuminate three surfaces of the X-cube, and the light is mixed in the X-cube and then exits from a light emitting surface. The electronic control element controls the red substrate, the green substrate, and the blue substrate. The light guide element is used for reflecting the light from the light emitting surface of the X-cube. The light valve element is used for reflecting the light from the light guide element back to the light guide element, and the light passes through the light guide element and then projected by the projection lens onto a projection plane area. Thereby, the ON/OFF switch time of the present invention is shortened, the temperature may not get over high, the optical efficiency is enhanced, and the whole volume is significantly reduced. | 08-04-2011 |

| 20090109695 | WIRE FIXING FRAME AND BACKLIGHT MODULE - A wire fixing frame for fixing at least one wire on a substrate is described. The wire fixing frame includes a main part, a first fixing part, a second fixing part, and an extending part. A wire outlet is defined between the extending part and the first fixed part, and a wire inlet is opposite to the wire outlet. A wire hold space is defined among the main part, the first fixing part, the second fixing part, and the substrate. The wire passes from the wire inlet to the wire outlet through the wire hold space, and the wire is fixed at a position by a round corner of the first fixing part and the extending part. | 04-30-2009 |
| 20100238649 | BACKLIGHT MODULE - A backlight module includes a back plate structure, a light source disposed in the back plate structure, at least one wire connected to the light source, and at least one wire fixing frame fixed on the back plate structure. Each wire fixing frame includes a main part, a first fixing part disposed on a side of the main part, a second fixing part disposed on a side of the main part and opposite to the first fixing part, and an extending part extending in a direction from the second fixing part to the first fixing part. A wire outlet is defined between the extending part and the first fixed part, and a wire inlet is opposite to the wire outlet. A wire hold space is defined among the main part, the first fixing part, the second fixing part, and the back plate structure. | 09-23-2010 |
