Embodiment 1
[0045] see figure 1 , an embodiment of the present invention provides a detection device for a display panel GOA circuit, including:
[0046] The signal providing unit 101 is configured to provide a test signal to the GOA circuit, the test signal at least includes a power signal, a clock signal and a trigger signal.
[0047] The obtaining unit 102 is used to determine whether each GOA unit in the GOA unit group of the GOA circuit has an output signal, and if so, obtain the output signal of each GOA unit in the GOA unit group; wherein, the GOA unit group includes at least the head end GOA of the GOA circuit unit and terminal GOA unit.
[0048] The processing unit 104 is configured to compare the acquired output signals of each GOA unit in the GOA unit group, and determine whether the GOA circuit is abnormal according to the comparison result.
[0049] In this embodiment, the GOA circuit is made to work by providing a test signal to the GOA circuit, at least the output signals...
Embodiment 2
[0069] see Image 6 , an embodiment of the present invention provides a detection method for a display panel GOA circuit, including:
[0070] 601. Provide a test signal to the GOA circuit, where the test signal includes at least a power signal, a clock signal, and a trigger signal.
[0071] 602. Determine whether each GOA unit in the GOA unit group of the GOA circuit has an output signal, and if so, obtain the output signal of each GOA unit in the GOA unit group; wherein, the GOA unit group includes at least the head end GOA unit and the end GOA of the GOA circuit unit.
