Abstract: The disclosure provides a manufacturing method for TFT array substrate, a TFT array substrate and a display device. The manufacturing method includes following steps: in sequence, forming a gate pattern layer, a gate insulating layer, a patterned poly-silicon layer, a separation layer on s substrate, and adopting a mask to form a source pattern layer and a drain pattern layer on the separation layer by photolithography processes. The source pattern layer and the drain pattern layer are connected to the patterned poly-silicon layer. The mask blocks one side of the channel area, and the same mask is adopted to form a lightly doped area on the other side of the channel area not blocked by the mask.

Abstract: A GOA circuit and LCD are disclosed. The GOA circuit includes cascaded GOA units and a control module. Each of the GOA units is driven by a first level of transfer clock, a second level of transfer clock, a first control clock and a second control clock to charge horizontal signal lines corresponding to a display area. The control module masks the first level of transfer clock and the second level of transfer clock when all of the horizontal signal lines are charged completely by the GOA circuit, such that the gate driving signals on the horizontal signal lines are discharged until the level equals to the predetermined level. In this way, the horizontal signal lines are prevented from generating redundant pulse signals before the first gate driving signals are outputted, which ensures the normal operations of the GOA circuit.

Abstract: A display panel, an array substrate, and a manufacturing method thereof, wherein the array substrate includes a thin film transistor device, and an interface layer, a first transparent conductive layer, a passivation layer, and a second transparent conductive layer which are formed on the thin film transistor device in sequence. By replacing a planarization layer in the prior art with the interface layer, performing a gate re-etching process, and perforating the interface layer and the passivation layer to simultaneously form a deep via and a shallow via, a number of photomasks required to form the array substrate is reduced to 8. It effectively reduces costs of production materials and costs of photomasks.

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: The present invention provides an array substrate, a manufacturing method thereof, and a display panel. Orthographic projections of channel layers of two types of thin film transistors in a design of a driving circuit on the array substrate at least partially overlap, that is, two thin film transistors are stacked on top of each other, thereby facilitating a narrow border design of the display panel. In addition, a channel layer of one of the thin film transistors is an amorphous oxide semiconductor layer, which can reduce node leakage in the driving circuit, which is conducive to improving circuit stability and reducing power consumption.
