LIGHT GUIDE FILM/Light Distribution Film/ LED backlight film

Light Guide Film (LGF) is a product designed according to market demand, which is specially produced to improve the existing light guide sheet. The lights below the buttons all come from the LED lights on the PCB motherboard. Traditional designs typically have 8-10 LEDs placed on each board. If the new design uses LGF, it can save a few LEDs and save a certain amount of SMT cost. The so-called LGF, that is, Light Guide Film, is an existing ordinary double-layer structure or EMI structure. A layer of LGF is added on the film to achieve a good light distribution effect.

• New Technology
  Different from traditional injection molded Light Guide Plates (LGP’s) or Light Guide Films (LGF’s).
• High Resolution patterns
   Nano-Imprinted onto Thin, Flexible Translucent Substrates.
• Light is guided in uniform or custom patterns
   Creating various required lighting effects designed by computer software.
• High resolution Nano-structures
    Uniquely allows for sophisticated control of light distribution to keys or buttons.
• Roll to Roll, high efficiency production line
    Provides very cost-effective and high quality products.

The thickness of the light guide film (LGF) is only 0.075mm~0.4mm, which can be designed according to the customer's organization. Through the surface microstructure, the sides of the LED light are refracted to obtain a uniform illumination effect.

We CAN design and assemble the light guide film to customers' products as per the specification, to provide the one-stop solution. 

Especially for the membrane switch with LED we have developed stable and high efficiency product to be compatible to our customer's products. You can also visit the light guide film type membrane switch for more details.
