复合绝缘层交流薄膜电致发光显示屏的综合设计

A UNIFIED DESIGN OF AC THIN FILM ELECTROLUMINESCENT DISPLAY PANELS

本文从交流薄膜电致发光（ＡＣＴＦＥＬ）显示屏的稳定性与可靠性角度出发，兼顾其发光亮度以及驱动电路对屏的ＲＣ响应的要求，对ＡＣＴＦＥＬ矩阵屏的结构进行了综合优化设计．从理论上分析了复合绝缘层ＳｉＯ２／Ｔａ２Ｏ５击穿方式的转变条件并计算了其合理的厚度比例及ＺｎＳ∶Ｍｎ发光层的厚度和衬底ＩＴＯ方块电阻的取值范围．通过实验对理论结果进行了验证，并在理论设计的指导下研制了６４０×４８０（１０英寸）ＺｎＳ∶ＭｎＡＣＴＦＥＬ单色计算机终端显示器．

his paper made a unified design of ACTFEL matrix display panels. For the purpose of realizing stable driving, high brightness and effective addressing. The optimium thickness ratio of SiO2/Ta2O2 double-stacked insolator layers, the thickness of ZnS∶Mn active layers and the time constant of the matrix display panels were calculated. The measured results of the electrical properties of SiO2/Ta2O2 insolator layers and the ACTFEL devices are in good agreement with the theoretical predictions. Under the guidance of theoretical design, a 640×480 computer terminal display with 10 inch in diagonal, was fabricated. The parameters of it are in accordance with the theoretical calculation.
