Black Backlight Membrane Switch Panel Waterproof Tactile Key Screen Printing
Black Backlight Membrane Switch Panel Waterproof Tactile Key Screen Printing
The use of elements in the alternating electric field generated by the alternating voltage is activated by the electronic impact of the conductive layer, a physical phenomenon that guides the jump, change, and recombination of the electron energy poles to emit high-efficiency luminescence, that is, electricity exciting light phenomenon.This kind of light has no temperature, so it is also called a cold light source.
EL cold light sheet is an advanced electroluminescent sheet with various outstanding advantages, which is made by using this principle and is widely used in communications, industrial control, CNC machinery, injection molding machinery, embroidery machines, sewing machine equipment, weighing equipment, frequency converters, household appliances, children's toys, instruments, meters, medical equipment, smart homes, electronic game machines, Military industry, aerospace, automobile, etc.
