[FPD] the original need 1000 now only 30 low cost LED backlight debut

[BP] the Nikkei news agency reported the Luminus Devices developed can greatly reduce the cost of LCD TV LED backlight backlight technology, and was demonstrated in the "FPD International 2007" exhibition. LED backlight for 52 Inch LCD TV, the original need for more than 1 thousand LED, and now only need to be 30. Due to the reduction of the number of LED use, it is also helpful to simplify color difference compensation with color sensors and software, is conducive to the realization of thin design. In order to reduce the number of the number of LED use, the new technology uses the LED chip configuration on both sides of the panel Light (Edge), instead of the original LED chip configuration on the back of the panel. End of the light type refers to the light emitted from the LED chip into the light guide plate, and through the light guide plate to change the direction of the light, and finally into the front side of the LCD panel. Due to the increase of the amount of light emitted each LED chip, and through the ingenious design makes these effective light into the light guide plate, so even if the use of LED a two reduction in the number of orders of magnitude can be obtained with the original level of backlight brightness. The amount of light emitted from each LED chip is achieved by increasing the size of the chip. In addition, through the formation of diffraction grating (Diffraction Grating) on the LED chip, increasing the proportion of light into a specific direction, can make the light from the LED chip into the light guide plate. The diffraction grating on the LED chip is made by wafer. LED uses red, green, blue three colors. The bottom plate (LED module) equipped with a tricolor LED chip and a driving element, etc., is combined with a horizontal elongated light guide plate, and the bottom plate is arranged on the bottom plate. 10 panels can be formed to support a 52 Inch panel. A reflecting mirror, a rear panel (Rear Tray) and an optical film are arranged on the bottom plate and the light guide plate arranged on the upper and the lower parts, so as to form a LED backlight unit. The LED module is manufactured by Luminus Devices, Taiwan Global Technologies Inc. (GLT), which combines the LED module with the GLT light guide plate manufactured by Lighting, and then assembled in the backlight unit. GLT plans to start production within 08 years of this LED backlight unit.
