altUltra-thin light guides from Global Lighting Technologies (Brecksville, OH) utilize the company’s LED-based edge-lighting technology to provide backlighting for touch-enabled display graphics. GLT’s light guides provide bright, uniform light where needed for directional symbols, on/off buttons, company logos, and any other graphic icons needing illumination. GLT’s edge-lighting technology employs side-firing, high-efficiency LEDs and focuses the light into a high-performance, ultra-thin light guide – 0.6 mm or less – utilizing light extraction technologies such as Microlens, which extracts light precisely where needed to provide bright, uniform light in a thinner form factor without hot spots or dark areas.
