Claim Text:
1. A testing system, comprising a thin film transistor substrate and a plurality of probes, the thin film transistor substrate comprising a plurality of thin film transistors and a plurality of connecting pads, each of the thin film transistors comprising a first electrode, a second electrode, and a third electrode, wherein the thin film transistor substrate further comprises a testing pad, one of the first electrode and the second electrode of each of the thin film transistors is electrically connected with one of the connecting pads, the third electrode and the other one of the first electrode and the second electrode of each of the thin film transistors are electrically connected with the testing pad, the thin film transistors are elements which are required to be tested on the thin film transistor substrate, the testing pad has a direct current voltage, it is determined whether the connecting pads have poor contact with the corresponding probes by respectively detecting whether the connecting pads have the direct current voltage, each of the thin film transistors electrically connected with the corresponding one of the connecting pads is directly connected to the testing pad.
