Lumvatech back lit panel "How It Works" demonstration. Light is injected into the side of the panel and travels internally until it reaches a pixel. The pixel reflects the light out of the panel so it is visible.
Thin light panels used to backlight Human Machine Interfaces. Dome, tactile, cap touch, proximity switches are used. The LEDs are moved away from the switch element to simplify assembly and improve operation. Isolated lighting on actuation, dual layer lighting, and backlighting are shown.
