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
