摘要
在模拟与仿真的基础上,根据MOS器件的源漏击穿特性,分析了用于a SiTFT有源驱动阵列的外围保护电路的工作原理;同时根据所采用的有源OLED单元像素驱动电路的特点,确定了电源线、数据线、信号线上的相应保护电路形式。该保护电路可应用于OLED的有源驱动TFT阵列。
The reasons of thin film transistor resource and drain punctured in large voltage condition are analyzed in this paper. An electrostatic diode circuit is designed based on circuit simulation by Am-spice software. This work is beneficial to the design of active matrix thin film transistor array for dri-ving organic light emitting display.
