EL Panels

Electroluminescence (EL) is an electrical phenomenon in which a material emits light when electricity is passed through it. Electroluminescent devices are actually lamps but instead of creating light by heating a filament, EL relies on phosphorescent materials which glow when exposed to a small electrical current.

EL lamps are extreme thin (0.1 – 0.6 mm), very flexible, with a high light intensity, are long living with up to 10000 hours and have a low power usage.They can be produced in a range of colors with green to blue-green being easiest and brightest, and a pure white being the most difficult. The light is very smooth and appealing to the spectator’s eye even at close distance.

EL finds usage in many applications such as regular or irregular backlighting for every kind of device, as a display for advertisement or interior design, backlight of keypad and even as a dashboard or design element in automobile.
