Give it the special look - EL for Keypad of every device

Our EL panels are ideal for Keypad backlighting of many controllers in daily use. They measure just 0.1 mm thick and are flexible, so they suit even the smallest and most thin devices. The original color of phosphor we are using ranges from green to blue or pink white, but we are also capable to produce other colors by printing another layer of colored ink on the surface. They emit equal brightness across the entire surface while consuming just 20mAh of power and remaining cold to the touch even within a long use.

With our efficient tooling process, we can develop your prototypes quickly and at low cost. Do you think your product would fit our EL products? Contact us and work with us together.
