An LCD does not emit light on its own — every image you see is illuminated by a backlight unit. The quality of that backlight directly shapes brightness, uniformity and color accuracy.
Anatomy of a Backlight
A typical backlight includes the LED light source, a light guide plate (LGP), optical films (diffuser, prism and reflector) and the frame. Together they distribute light evenly across the entire screen.
Optimizing Performance
- Brightness: tuned from standard indoor to high-brightness outdoor panels
- Uniformity: minimized hot spots for even illumination
- Color: matched LEDs and films for accurate, consistent color
- Efficiency: low power for portable and battery-powered devices
