The EL emission spectra show that the brightness of the novel structure devices greatly increases compared with that of devices with traditional double insulator structure, and the ratio of blue emission to red emission of the novel structure device is also improved. The improvement of the EL characteristics of this kind TFEL device is attributed to both of the electron acceleration and the ZnS/SiO 2 interface.展开更多
众所周知,薄膜 EL 显示器具有许多优点,例如快速响应、宽视角、长寿命,利用光刻技术可获得高分辨率及功耗低等。但是,尽管人们付出了很大的努力,到目前为止仍未获得高亮度的红蓝发光材料。这是实现全色 EL 显示器的一大障碍。为了实现...众所周知,薄膜 EL 显示器具有许多优点,例如快速响应、宽视角、长寿命,利用光刻技术可获得高分辨率及功耗低等。但是,尽管人们付出了很大的努力,到目前为止仍未获得高亮度的红蓝发光材料。这是实现全色 EL 显示器的一大障碍。为了实现全色显示,日本 T.Suzuki 等人研究了 a—Si TFT 驱动有源矩阵 EL展开更多
