摘要
采用丝网印刷技术,在Al_2O_3陶瓷板上印刷、高温烧结内电极及绝缘层制备出陶瓷厚膜基板,进而制备了新型厚膜电致发光显示器(TDEL),整个器件结构为陶瓷基板/内电极/厚膜绝缘层/发光层/薄膜绝缘层/ITO透明电极。对用不同薄膜绝缘材料制备的显示器件的特性进行测试、比较、分析,结果表明薄膜绝缘介质层对器件的阈值电压、发光亮度均有一定的影响,以复合绝缘层的性能最优。最后对器件的衰减特性进行了初步分析。
With screen-printing technique, a ceramic thick film substrate was fabricated by printing and sintering Ag/Pt alloy internal electrodes and high dielectric constant ceramic thick film insulating layer on A1203 ceramic substrate. Thereby a novel TDEL device was prepared using the ceramic thick film substrate. The whole structure of the device is ceramic substrate/internal electrodes/thick dielectric film/light-emitting layer/thin dielectric film/ITO. The TDEL devices were made by using different dielectric material, and these devices＇ properties were measured and compared. Effect of thin dielectric film on threshold voltage and brightness was analyzed. Besides, the decay characteristic of the devices was also measured and analyzed.
