CoActive Technologies KDM (Newton, MA) has expanded its family of light guide foils to include devices with a thickness of less than 200μm. The light guide foils are designed to evenly distribute light from side-firing LEDs, providing bright, uniform illumination of keypads for handheld electronic devices. Backlight coloring can be software-controlled through the use of multiple sets of colored or RGB LEDs, while use of multiple light guide foils provides a zoned illumination effect. Light guide foils are constructed with poly-carbonate or TPU film materials. Typical luminance is >20Cd/m2 from two LEDs at 5mA/LED.
