    Product Feature:

    LGF backlight membrane switch is a backlight effect with unique appearance design. 

    A kind of new material namely light guide film is used on the basis of traditional 

    membrane switch, with the characteristics, when the LED light flash out on the light film 

    and after diffusion ,It can have the effect of t backlight. Compared with the traditional

    EL backlight, production process is relatively simple and much easier to drive for LGF backlight.
