Global Lighting Technologies (GLT), Brecksville, OH, is offering ultra-thin light guides that utilize the company’s unique, LED-based, edge-lighting technology to provide a solution for backlighting touch-enabled display graphics in various applications. The light guides reportedly provide bright, uniform light for directional symbols, on/off buttons, company logos, rotary switches, sliders and touchpads.
The light guides’ ultra-thin profile is suitable for front-panel graphic interfaces that employ capacitive or field-effect touch technology. Placed between the PC board/circuit sensor and the graphic overlay, their extreme thinness facilitates signal transmission from the graphic overlay through the backlight and to the sensor. The user can touch right through them with no loss of sensitivity.
