Abstract: A manufacturing method for LTPS TFT substrate is disclosed. Through performing two etchings on the gate metal layer, ion heavy doping and ion light doping of the polysilicon active layer are performed in a self-aligned manner such that the LDD structure of the polysilicon active layer is symmetrically distributed on two sides of the gate electrode, which is beneficial to improve device characteristics, is more stable and reliable than the conventional technology, and can reduce the number of process masks, save mask cost, operation cost, material cost and the time cost. The thinning process of the gate insulation layer can reduce the thickness of the gate insulation layer corresponding to the heavily doped region of the polysilicon active layer, so that the ion implantation efficiency can be effectively improved.

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. 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 contact regions formed of the controllable resistance spacer layers are respectively connected with 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.
