EL cold light film (LCD backlight) supply EL cold light film (LCD backlight)

Electroluminescent (Electro Luminescent) referred to as EL, it is a phenomenon of light energy into electrical energy, but because of the operation of the process will not heat, it is generally known as "cold."

EL Product Principle Description:

EL structure:

EL cold light tablets for the sandwich-type structure, have a lower electrode, the surface insulation layer made of imported UV, the electrode for the transparent conductive film (ITO film), the light from this side injection, the lower electrode as the back electrode, the main material for silver or carbon, light-emitting materials are mainly zinc sulfide (ZnS), when the AC voltage is applied to two electrodes, the electric field makes the (ZnS) particles have pumped jump, resulting in a charge-discharge cycle of each LED, when it contains different active agent, may issue a different color of light. EL brightness as the voltage between the electrodes, the change of frequency changes in a certain range of voltage and frequency increased with a corresponding increase in brightness.

EL advantages:

1. Ultra-thin - the thinnest of up to 0.1mm or less. (The same thickness as ordinary photos)

2. Can be flashing - flashing according to customer design speed, frequency and requirements of production (such as FLASH effect)

3. Can be bent - paste or suspension under the light in a variety of shapes;

4. Do not heat - electroluminescent film is a cold light source, at work and almost no temperature, working temperature lower than the fluorescent lamps;

5. A good light - the light uniformity, soft, and its light does not flash, does not make eye tension, fatigue; (uniformity of up to 95%)

6. Long Life - EL is based on the life of the half-life (half brightness) to measure, usually the time of 3000-5000 hours;

7. Power consumption low - very low in power consumption will be light, the power consumption of milliwatts. (Cold light source, power ninety-seven% into light, no heat loss);

8. Harmless - no ultraviolet light, without adverse effects on the human body for green products;

9. --- Any shape can produce various shapes according to user needs, the length of free cutting;

10. Earthquake good - electroluminescent film different from other light-emitting devices, and its not easy to face the outside world due to the impact of the failure.

11. Easy to operate: 10 minutes to complete the installation or replacement of ad film

Application:

Can be widely used: communication products such as: MP3, MP4, decoration, flashing billboards, instruments, lighting, LED LOGO, electronic watches, all kinds of LCD liquid crystal display control panel, keypad backlighting,,,, et al.
