Active matrix image sensing panel and apparatus

摘要

An active matrix image sensing panel comprises a substrate and an image sensing pixel. The image sensing pixel is disposed on the substrate and comprises a scan line, a data line crossing the scan line, a photo sensing element and a TFT element. The photo sensing element includes a first terminal electrode and a second terminal electrode, and the voltage of the first terminal electrode is higher than that of the second terminal electrode. The TFT element includes a first electrode, a second electrode, a first gate electrode and a second gate electrode. The first electrode is electrically connected to the data line, the second electrode is electrically connected to the first terminal electrode, the first gate electrode is electrically connected to the scan line, and the second gate electrode is electrically connected to the first or second terminal electrode. An active matrix image sensing apparatus is also disclosed.
