LGF (Light guide film)

What is LGF?

• Light Guide Film (LGF) is a thin, optically clear plastic sheet designed to evenly distribute light from an edge-lit source across its surface. This technology is essential for creating uniform backlighting in various applications, from backlit keyboards and LCD displays to signage and automotive interiors.

How Does Light Guide Film Work?

• LGF utilizes a unique micro-structure on its surface to capture and refract light from an LED light source positioned at the film’s edge. This light is then evenly dispersed across the film’s surface, producing a bright and consistent illumination.

Features

• Display applications: Front light guide film for E-paper and public signage and other display applicaitons.
• Automotive: Instrument panel /door scuff plate/ interrior illumination for car.
• Consumer Electronic:  illuminated keyboards / RGB Led fans / control panels.
• Home applications: illuminated touch buttons
