Claim:
1. An array substrate for a display device, comprising a plurality of data lines and a plurality of common electrode lines, wherein, the array substrate further comprises at least one discharge unit, a driving circuit, a switching signal line connected to an output terminal of the driving circuit, and at least one electrostatic protection unit, each discharge unit corresponds to one of the plurality of data lines, and is connected between the corresponding data line and one of the plurality of common electrode lines, and each discharge unit is capable of selectively conducting the data line to the common electrode line connected thereto, wherein the discharge unit conducts the data line to the common electrode connected thereto only in a non-display period of the display device; each of the at least one electrostatic protection unit corresponds to one of the plurality of data lines and is provided between the corresponding data line and the switching signal line, and static electricity on the data line is released to the switching signal line via the electrostatic protection unit; and each of the at least one electrostatic protection unit comprises a second thin film transistor and a third thin film transistor, wherein, the second thin film transistor is a N-type thin film transistor and the third thin film transistor is a P-type thin film transistor; or the second thin film transistor is a P-type thin film transistor and the third thin film transistor is a N-type thin film transistor; and one of a source and a drain of the second thin film transistor is connected to the switching signal line and the other is connected to the data line, a gate of the second thin film transistor is connected to the switching signal line, one of a source and a drain of the third thin film transistor is connected to the data line and the other is connected to the switching signal line, a gate of the third thin film transistor is connected to the data line.
