Electroluminescent Powder
About electroluminescent powder

Other key words: EL powder, Electroluminescence phosphor, Electronic excitated glow pigment

EL electroluminescent powder series products are the direct conversion of electrical energy to light powdery luminescent material. It is to produce low-light Degree, the surface light source, low energy consumption on the basis of material, its products have luminous brightness, format freedom, light weight can be used with Different power to achieve a large area and the local light-emitting luminous animation and dynamic change. So widely used On the LCD backlight, print ads, animation ads; nameplate, instruments, toys, costume jewelry, Watch the back lighting. We supply the phosphor brightness, long life, low power consumption, the fine powder particles uniform, pure luminous colors; the color has been formed on the light emitting from the deep blue, Highland, sky blue, blue green, green blue, green, green, orange, white and even, with a complete LED series. We can flexibly adjust the production process to meet the user light-emitting phosphor color, brightness, lifetime and particle size requirements. Leading quality, reliable and stable quality, first-class quality and personalized service, has won recognition and trust of customers at home and abroad.
