This thin, LED-based backlight is designed for use with desktop or notebook PC keyboards. The backlight design uses the company’s patented 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. The design employs side-firing LEDs that focus their light into a high-performance light guide. The thin structure reduces high cost and power consumption associated with other backlighting methods such as screen-printed light guides or direct LED lighting.
