Thin film backlighting is a light-guide solution with embedded LEDs and capacitive switch sensors that provides illuminated control, display indicators and ambient lighting for user interfaces and illuminated control panels.
The patented thin film printed light-guide manufactured by TT Electronics uses specialised printing processes using side emitting LEDs embedded within the light-guide structure.
Thin film backlighting can be used on switches, keypads and keyboards. LGF backlighting can be directly placed over metal domes. Light transmitted through the tight area resulting in a uniform distribution, ensuring no light leakage between specific colours and areas.
