建立了有源矩阵液晶显示器中周边驱动缓冲寄存器的等效电路模型。利用 Ｔ Ｆ Ｔ 的线性近似和 Ｅｌｍ ｏｒｅ 模型， 计算了周边驱动电路中的信号失真， 讨论了栅延迟与金属栅电极材料的关系及对 Ｔ Ｆ Ｔ 开态电阻的要求。
The equivalent circuit model of peripheral driving buffer in active matrix liquid crystal display is established. The signal distortion in the peripheral driving circuit was calculated by using the linear approximation of T F T and the Elm ore model. The relationship between gate delay and metal gate electrode material and the requirement of T F T on-resistance were discussed.
