早已为人们熟知的ZnS:Cu一类粉末层交流电致发光(“EL”)用于信息显示,虽其成本较低,到目前为止还是没有得到成功。 通过现行一些方法的新的组合,我们已经消除了它的一些障碍,使EL变成可与发光二极管相匹敌,特别是在多象元、大面积显示或者是需要兰色、绿色、白色或带颜色的那些场合。 以前的电致发光层主要缺点是迅速老化,这一点已经由Lehmann的“超长寿”处理 Already known as ZnS: Cu Powder layers of alternating current electroluminescence (“EL”) for information display, although its cost is low, has so far been unsuccessful. With some new combinations of current approaches, we’ve eliminated some of the hurdles that make the EL comparable to light-emitting diodes, especially on multi-pixel, large-area displays or the need for blue, green, white, or ribbon Color those occasions. The main disadvantage of previous electroluminescent layers is rapid aging, which has been handled by Lehmann’s “Ultra Long Life”
