Problems solved by technology
Since the signal lines integrated on the array substrate are relatively dense, it is easy to cause a short circuit between the signal lines on the array substrate, and the signal line itself is also prone to open circuit, resulting in poor display.

Description
technical field [0001] The present invention relates to the field of display technology, in particular to a detection circuit, an array substrate, and a display panel. Background technique [0002] The array substrate is generally integrated with various signal lines, and the various signal lines include at least one gate and various data lines. For example, the gate may include a signal line for providing a gate driving signal to the pixel driving circuit, and a signal line for providing a control signal to the gate of the sensing transistor in the pixel driving circuit. The data lines may include signal lines for providing data signals to the pixel driving circuit, signal lines for providing power signals to the pixel driving circuit, and sensing signal lines connected to the source / drain of the sensing transistor in the pixel driving circuit. Since the signal lines integrated on the array substrate are relatively dense, it is easy to cause a short circuit between the sig...
