Case study
Side-Entry LED Backlight Unit
Light injected from the edge so the panel stays thin, with the light guide matched to the customer outline.
The requirement
The housing allowed only a few millimetres behind the panel, which rules out a bottom-lit arrangement with a diffuser gap.
What we supplied
- Side-entry light guide with the LEDs on one edge
- Reflector and diffuser stack tuned for the required uniformity
- Brightness and colour temperature agreed against a measured sample
- Outline matched to the panel aperture
Trade-off to know about
Edge lighting keeps the assembly thin, but it is less forgiving than bottom lighting on large areas: the guide thickness and the LED pitch have to be right from the start.
