Abstract: A photo sensor, a manufacturing method thereof, and a display panel are disclosed. By an ion implantation method forming an N-type region and a P-type region on a surface of polycrystalline silicon in a same layer respectively, compatibility with an ion implantation process is ensured, while covering a layer of an amorphous silicon photosensitive layer on the polycrystalline silicon enhances light absorption ability and can increase photo-generated electron-hole pairs. Furthermore, built-in electric fields exist on a horizontal direction and a vertical direction, which can more effectively separate the electron-hole pairs to enhance photo-generated electric current to improve accuracy of fingerprint recognition.

Abstract: A gate driving circuit and a display panel are disclosed. A pull-up control module and a pull-down module of each stage gate driving unit are connected to a first node. A thin film transistor in the pull-up control module and/or pull-down module that is connected to the first node is an oxide thin film transistor, such that a leakage current of the first node is reduced due to the advantage of the small off-state leakage current of the oxide thin film transistor. Therefore, the voltage level of the first node can remain stable during a pull-up stage and a touch suspension stage.
