GENERAL ELECTROLUMINESCENT (EL) BACKLIGHTING FEATURES
Nelson-Miller 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.
EL backlighting solutions are best suited for low to no-light applications, where the backlight is not always on. That is due to the properties of phosphors that tend to decay with extended use at high voltages and frequencies.
