align="justify">It's reported that Global Lighting Technologies (GLT) has introduced an 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 employs side-firing LEDs that focus their light into a high-performance light guide. Using optical simulations, GLT's designers can optimize uniformity, and, in some cases, use diversion features that are molded directly into the light guide to "bend" a portion of the light around a potential thru-hole, resulting in a very uniform backlight that gets more collimated light from the light guide through to the keyboard. LEDs can be located on the edge of the light guide, or in some cases, in the middle of the backlight, depending-upon the surrounding geometry.
