交流粉末电致发光显示器具有制作工艺简单、电-光转换效率高以及色调柔和、美观等特点,已被广泛应用于平板型特种光源、模拟字母数字显示领域。由于效率高,一直被认为是大屏幕显示的选择方案。它的两个主要问题是亮度低和发光阈值电压低。多年来人们从材料、工艺、驱动电路等不同方面作了大量的努力以提高矩阵电致发光屏的性能,始终未取得
AC powder electroluminescent display has the advantages of simple manufacturing process, high electro-optical conversion efficiency, soft color, beautiful appearance and the like, and has been widely applied to the field of plate type special light source and analog alphanumeric display. Due to its high efficiency, it has long been considered a choice for large screen displays. Its two main problems are low brightness and low threshold voltage. Over the years, people have made great efforts to improve the performance of matrix electroluminescent screens from different aspects such as materials, processes and driving circuits, and have never been obtained
