Abstract: A manufacturing method of a TFT substrate uses a top gate structure and the entire process can be completely done with seven masks. The number of masks used is reduced. The manufacturing process of a TFT substrate is simplified. Product yield can be increased to effectively improve productivity. Heavy and light ion doping can be simultaneously achieved with one single doping operation so that manufacturing cost can be reduced. By subjecting two ends of a semiconductor pattern to heavy ion doping to form a source electrode and a drain electrode, the manufacturing steps can be reduced and the source electrode and the drain electrode so formed do not need to extend through a via hole formed in an interlayer dielectric layer to contact the two ends of the active layer thereby effectively reducing contact resistance and improving product yield. Also provided is a TFT substrate manufactured with the method.

Abstract: Provided is a TFT array substrate, which increases the area of a drain electrode of a TFT within a light-shielding zone to have the drain electrode overlapping a portion of a horizontal projection of a common electrode, wherein the drain electrode and the common electrode constitute a first storage capacitor and a pixel electrode and the common electrode constitute a second storage capacitor. The pixel electrode and the drain electrode are electrically connected and thus are of the same potential. The first storage capacitor and the second storage capacitor are connected in parallel and collectively form a storage capacitor such that the storage capacitor has a capacity that is equal to the sum of capacities of the first storage capacitor and the second storage capacitor, whereby, without reducing aperture ratio, the capacity of the storage capacitor is increased, crosstalk and image sticking are alleviated, and product display quality is enhanced.

Abstract: Provided is a method for manufacturing an array substrate, in which a planarization layer mask includes a strip pattern that is provided for forming a groove and has two opposite sides along which taper modification patterns are provided so as to reduce taper of a groove formed in a planarization layer, making a slope thereof less steep, thereby preventing shorting of signal lines caused by residues of metal or ITO in a subsequent operation and thus increasing product yield. For the groove associated portion of an array substrate involving an in-cell touch structure, there is no need to change line for the touch sensing lines so as to lower down the difficulty of the operation and increase product yield.
