This further utilizes the NIL technology in conjunction with dry-etching to perform the nano-scale patterning on a heterogeneous substrate, such as Si, sapphire or the like. | 10-01-2015 |

20130170216 | ADJUSTABLE LED LENS AND LAMP WITH THE SAME - The adjustable LED lens has a body having a light incident surface and a light-emitting surface respectively mounted on two opposite sides of the body. The light-emitting surface has a concave tapered surface. The adjustable LED lens is mounted on a holder. A distance between the adjustable LED lens and the holder is changeable. An LED is mounted on the holder, wherein a light generated by the LED passes through the light incident surface and the light-emitting surface of the body. The concave tapered surface of the light-emitting surface increases a light distribution angle to increase an illumination range and decrease a glare. The distance between the adjustable LED lens and the LED is changeable to adjust a light shape as desired. | 07-04-2013 |

20110109830 | BACK COVER MODULE AND ASSEMBLING METHOD THEREOF, BACKLIGHT MODULE AND ASSEMBLING METHOD THEREOF, AND FLAT PANEL DISPLAY DEVICE AND ASSEMBLING METHOD THEREOF - A back cover module and assembling method thereof, a backlight module and assembling method thereof, and a flat panel display device and assembling method thereof are disclosed. The flat panel display device includes the backlight module and a display panel disposed on the backlight module. The backlight module includes the back cover module, a reflector disposed on an inner surface of a back cover body of the back cover module, and a light source module disposed on the reflector. The back cover module includes the back cover body, a first U-shaped plastic frame, and a second U-shaped plastic frame. The first and second U-shaped plastic frames are fixed at four corners of the back cover body. By the present invention, a size of the back cover body can be reduced so as to achieve objectives of decreasing cost and weight of the flat panel display device. | 05-12-2011 |
