Light Guide Film

The light Guide Film (LGF) product line is unique and offers several advantages over more traditional backlighting methods. One such advantage is its ability to evenly flood light your product without creating hotspots. The keys which are farther away from the light source appear to be the same intensity as the keys closer to the light source. This is accomplished by a special process of printing on PETfilm.

Light Guide Film is very thin, which allows the overall thickness of your keypad, or similar product, to remain thin and flexible if desired. The LGF can also be placed directly onto a rigid PCB by means of a double sided adhesive if so desired.

Due to the light gathering properties of Light Guide Film, fewer LEOs can be used in the product, which in turn means less cost for the lighting and less power drain for portable devices.

LGF can be utilized behind silicone rubber keypads, membrane switches, IMD keypads and even for backlighting plastic housings, or enclosures manufactured of different materials. Essentially, anything you desire to backlight can utilize LGF.

Keypads which backlight with LGF can be non-tactile, or metal dome arrays can be incorporated to provide tactile feel without detracting from the lighting performance.
