Abstract: A GOA circuit and a liquid crystal device (LCD) are disclosed. The GOA circuit includes a plurality of GOA units and a control module. Each of the cascaded GOA units is configured for charging corresponding horizontal scanning lines within a display area when being driven by a first level clock, a second level clock, a first control clock, and a second control clock. After the horizontal scanning lines are fully charged by the GOA circuit, the control module is configured for resetting the gate driving signals to be at the first level, i.e., the invalid level, via the turn-on pulse signals and the negative-voltage constant-voltage source.

Abstract: The disclosure provides a liquid crystal display panel, an array substrate and a manufacturing method thereof. In the method, controllable resistance spacer layers are formed on at least one of a source doped region and a drain doped region of a low temperature polysilicon active layer, wherein when a turn-on signal is not applied to the gate layer, the controllable resistance spacer layers serve as a blocking action for a flowing current, and when the turn-on signal is applied to the gate layer, the controllable resistance spacer layers serve as a conducting action for the flowing current, such that a contact region formed of the controllable resistance spacer layers is connected the corresponding source layer and the corresponding drain through the controllable resistance spacer layers. Therefore, the disclosure is capable of effectively decreasing a leakage of a thin film transistor.

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.
