El Backlight Display For Lcd Application: Workshop

we are the topmost exporter and manufacturer of EL Backlight Display for LCD in Shenzhen, Guangdong, China. Electroluminescent devices (EL), it is working principle can be described as follows:

inorganic photoelectric materials such as particles of zinc sulfide are activated in the AC electric field driving by AC voltage adding sandwiched between the poles
Second: accelerated electrons within the light-emitting layer (inorganic photoelectric materials) move at high speed to activate the atoms, which are accelerated and gain enough energy. electrons excited by electric field will crash the luminescence centers and fluorescence material, leading to the emitting of a kind of luminescence with high-efficient, which results from the process of electron transition leap-change recombination, this is physical phenomenon, namely electric excitation light phenomenon
