摘要： A display module includes a display panel and a detection circuit. The display panel has a display area and a bezel area located beside the display area. The display panel includes a first detection line disposed in the bezel area. The first detection line is coupled to at least one detection signal receiving terminal and at least one detection signal output terminal. The detection circuit is coupled to a detection signal input terminal and a first detection signal detecting terminal. The detection signal input terminal is coupled to the at least one detection signal receiving terminal, and the at least one detection signal output terminal is coupled to the first detection signal detecting terminal. The detection circuit is configured to: generate and transmit a detection signal to the first detection line; and receive the detection signal passing through the first detection line.
