 有益效果
相较于现有技术，本申请提供的一种发光电化学池及电致发光显示装置，发光电化学池区别于有机电致发光二极管的机理主要在于：自由移动的离子起了发光的主导作用；而有机电致发光二极管中起主导作用的却是不同极性载流子的定向移动。发光电化学池本身具有离子移动性的特点，与有机电致发光二极管相比具有较低的启亮电压，较简单的器件的结构，使用空气稳定性金属做电极等特点。在本发明中使用发光电化学池来构建电致发光显示装置，从而作为像素单元，实现电致发光显示。通过选用不同的发光区间的荧光材料，分别实现红绿蓝三色发光，进而获得全彩色显示。该显示器件只有阴极、发光层和阳极三层结构，结构简单、制备方便、且电极与发光层间不需要公函匹配、电极选择性多、可以采用惰性金属。
