Embodiment 1
[0031] figure 2 It is a schematic structural diagram of a test circuit provided by Embodiment 1 of the present invention. Such as figure 2 As shown, the test circuit includes a first signal input line Test Input1, a first signal output line Test Pad1 and a plurality of first thin film transistors T1. The first signal input line Test Input1 is connected to the gate of the first thin film transistor T1, the first signal output line Test Pad1 is connected to the first electrode of the first thin film transistor T1, and the first thin film The second pole of the transistor T1 is connected to the driving circuit 101 through gate lines (Gate 1, Gate 2 . . . Gate End). Optionally, the driving circuit 101 includes a gate driving circuit, a reset driving circuit, and an emission driving circuit. In practical applications, the test circuit can also be applied to other driving circuits. The test circuit provided in this embodiment can not only evaluate the overall driving effect of...
