Low-cost and low-voltage active matrix displays were fabricated by simply patterning gate electrode arrays on a polymer electrolyte (PE)-coated polymer light-emitting diode (PLED). Structurally, a PE capacitor seamlessly stacked on a PLED by sharing a common Al:LiF composite electrode (PEC|PLED). This monolithic integrated organic optoelectronic device was characterized and interpreted as the tunable work function (surface potential) because of the perturbation of accumulated ions on Al:LiF composite electrode by PEC charging and discharging. The modulation of electron injection by the PEC resulted in increases in the electroluminescent brightness, from <100 cd m to >8000 cd m, and the external quantum efficiency from <0.025% to 2.4%.
通过在聚合物电解质（PE）涂层聚合物发光二极管（PLED）上简单地图案化栅电极阵列，制造出低成本、低电压的有源矩阵显示器。结构上，通过共享公共的 Al：LiF 复合电极（PEC|PLED），PE 电容器与 PLED 无缝堆叠。由于 PEC 充电和放电对 Al：LiF 复合电极上积累离子的干扰，这种单片集成的有机光电设备的工作功能（表面电位）可以被表征和解释。PEC 对电子注入的调制导致电致发光亮度从 <100 cd m 增加到 >8000 cd m，外量子效率从 <0.025% 增加到 2.4%。
