As a switching device, TFT in AMLCD operates in saturation mode. Its source contact is always connected to the data bus (video), and the drain to the pixel electrode.
作为开关器件,AMLCD中的TFT工作在饱和模式,其源极总是连接数据总线(视频),漏极接像素电极。

The high aperture ratio is achieved by overlapping ITO pixel electrode and bus line using a photo_sensitive polymer.
