Background technology

Electroluminescent, can claim again electroluminescence, is called for short EL, is that voltage by being added in two electrodes produces electric field, the electronics percussion centre of luminescence being excited by electric field, and cause leap, the variation of electron solutions level, a kind of physical phenomenon of composite guide photoluminescence. The example of electroluminescent material comprises adulterated copper and silver-colored zinc sulphide and blue diamond. EL sheet is placed in luminescent powder between two plate electrodes and forms. It is sandwich type structure, respectively there is up and down an electrode, the very nesa coating that powers on, light from then on face penetrates, bottom electrode is back electrode, its material is mainly silver or carbon, and luminescent material is mainly zinc sulphide, in the time that alternating voltage is added on two electrodes, electric field makes zinc sulphide particles produce excitation formula transition, thereby charge and discharge in circulation luminously at each, in the time that it contains different activator, can send the light of different colours. The brightness of EL changes with the change of interelectrode voltage, frequency, generally with the also corresponding increase of increase brightness of voltage and frequency. At present, the surperficial picture and text of the EL sheet that existing light-emitting device adopts are all planes, and illumination effect is not so good like this, and the surperficial picture and text of product easily scratch, rub resistance, sense of touch are not bad.
