Detection method and apparatus for display panel, detection device and storage medium

A detection apparatus for a display panel, wherein the display panel comprises a plurality of data lines, a plurality of gate lines, and a plurality of pixel units enclosed by the plurality of data lines and the plurality of gate lines in an intersected manner;

• at least a part of the pixel units comprises a driving circuit and a pixel electrode that are connected with each other;
• the driving circuit is further connected to a data input end, a gate electrode scan input end and a power source end, respectively;
• and the apparatus comprises:
• a second input module configured to provide a second data signal to the data input end, provide a second gate line scan signal to the gate electrode scan input end, and provide a power source signal to the power source end, wherein during a signal inputting process, the second data signal is at a first level, a level of the second gate line scan signal jumps from the first level to a second level, a level of the power source signal jumps from the first level to the second level, and the level of the second gate line scan signal jumps before the jumping of the level of the power source signal;
• a second acquirement module configured to acquire a second voltage of each pixel electrode;
• and
• a second determination module configured to determine a faulty gate line according to the second voltage.
