LED backlight membrane switch/cap touch keypad

More and more users require backlighting in membrane switch or capacitive touch keypad application. Backlighting is a good way to enhance the user experience and differentiate your equipment from the competition. There are a few ways to provide backlight to membrane or capacitive touch keypad. ElecFlex can guide you in the most cost-effective backlighting technique for your user-interface assembly.

LGF(light guiding film) backlighting solution introduction

Light Guide Films are unique using Semiconductor technology to print the very small (20 to 50 micron dia.) micro-lens arrays that redirect light out of the films only where it is needed. In most keypad applications, side-firing LEDs are applied as light source, which bring you uniform lights by reflecting inside the light guide film. Even the metal domes or conductive pads cannot block the lights. LGF solution is now considered the most popular and cost-effective backlight solution. ElecFlex is able to provide the complete design and manufacturing service of backlit membrane keypad or capacitive touch keypad.
