Brightness enhancement film for backlight module from GUTE TEK PLASTIC

The optical plastic sheet in the backlight module determines the efficiency of the whole module. The brightening enhancement film (BEF) with prismatic microstructure (also known as prismatic sheet and condenser) can effectively improve the lighting brightness, uniformity and image contrast, and indirectly improve the power consumption performance of the backlight module. Generally, TFT-LCD display needs one or two brightening enhancement films. The mechanism is to concentrate the scattered light to the front, to improve the brightness of the front and recycle the unused light outside the viewing angle by using the reflection of light, so as to reduce the loss of light. Moreover, it indirectly achieves the benefits of energy conservation, low carbon and environmental protection.
