Global Lighting Technologies (GLT), Inc. has introduced a thinner, LED-based backlight for use with desktop or notebook PC keyboards that provides brightness and uniformity, along with the opportunity to utilize fewer LEDs, reducing the cost of the backlight. The backlight design utilizes the company’s MicroLens light extraction technology and optical engineering expertise to extract more light from the backlight through to the keyboard, increasing brightness while spreading the light more uniformly. Typical backlight thicknesses that can be provided for desktop keyboards in the 0.6 mm to 0.8 mm range. For laptop keyboards, even thinner backlights in the range of 0.3 mm to 0.4 mm can be realized.
