Abstract
The present disclosure relates to a detection circuit. The detection circuit includes a first input circuit and a second input circuit. The first input circuit has multiple first switch units, each of which being disposed in a one-to-one correspondence with one of multiple first signal lines. The second input circuit has multiple second switch units connected in a cascade arrangement, each of which being disposed in a one-to-one correspondence with one of multiple first signal lines. A second terminal of the second switch unit in a previous stage is connected to a first terminal of the second switch unit in the next adjacent stage. The first terminal of the second switch unit of a first stage is connected to a second terminal of a corresponding first signal line. The second terminal of the second switch unit of a last stage is connected to a first detection terminal.
