|20150253622||LIGHT EMITTING DIODE LIGHT SOURCE, MANUFACTURING METHOD THEREOF, BACKLIGHT SOURCE AND DISPLAY DEVICE - The present invention provides a LED light source for increasing a light emitting angle and a manufacturing method thereof, as well as a backlight source and a display device. A LED light source comprises a circuit board, a LED which is directly fixed on and electrically connected to the circuit board, and a packaging piece for packaging a LED light emitting chip. A prism film with a prism micro-structure may be arranged between the packaging piece and the LED.||09-10-2015|
|20140168949||Direct Type Backlight and Display Device - The present invention provides a direct type backlight and a display device provided with the direct type backlight. The direct type backlight includes: a backplate; a printed circuit board fixed on the backplate; a number of LED lamp units fixed on the printed circuit board; side frames fixed on inner side walls of the backplate; reflection sheets covering inner wall of cavity formed by the printed circuit board and the side frames, said reflection sheets have lamp holes matching the LED lamp units; outer frames fixed on upper sides of the backplate and the side frames; said direct type backlight further including: a silica gel light guide plate which this the cavity formed by the printed circuit board and the side frames to cover the reflection sheets and the LED lamp units; and optical film disposed on upper surface of the silica gel light guide plate and located between the upper surface of the silica gel light guide plate and the outer frames. By diffusing the light rays emitted from the LED lamps through the silica gel light guide plate, the mixing distance of the LED lamp is shortened, thus the thickness of the direct type backlight is reduced and the display device becomes much thinner.||06-19-2014|
|20140167063||LED CHIP PACKAGING STRUCTURE, ITS MANUFACTURING METHOD, AND DISPLAY DEVICE - A LED chip packaging structure, its manufacturing method, and a display device are disclosed. A conductive unit is formed at two opposite sides of a LED chip unit, and comprises a first conductive layer formed at a side of, and electrically connected to, a first electrode, a second conductive layer formed at a side of, and electrically connected to, a second electrode, and an intermediate isolation layer formed at a side of a GaN layer. The LED chip unit and the conductive unit are connected laterally to form an electrical-connection channel as a whole, without welding a gold wire for the conductive channel as in a traditional LED. Thus, the method is able to reduce the total thickness of the LED chip device, increase the thermal conductivity effect of the LED chip and the overall stability, and improve the light-extraction effect of the surface of the LED chip.||06-19-2014|
