ELECTROLUMINESCENT BACKLIGHTING SOLUTIONS:

POLARIS-KEYPAD implements electroluminescent (EL) backlighting solutions for membrane switches and other various customer applications by printing phosphors between two conductive layers. Phosphors emit light when a DC Voltage is applied to them through one of the transparent conductive layers.

1. material: PET or PC;
2. adhesive: 3M adhesive;
3. type: flat,embossed,or metal dome; 

4. backlight resource: El (with or without driver);
4. Passed ISO9001,ROHS;

Notice: We have the capacity to provide you membrane switches with other special requirements, such as Shielding, Windows/Lens Coating, Embossing, Embedded LEDs, UV glossy/matte/textured, etc.
