Abstract: According to the present disclosure, a display panel and a circuit board assembly are provided, and the circuit board assembly includes a first circuit board, a second circuit board, a third circuit board, a first connector and a second connector. The first circuit board is provided with a power supply module, a balance resistor and a plurality of first power supply lines. The balance resistor is connected to the power supply module and each of the first power supply lines. The second circuit board is provided with a plurality of second power supply lines, the third circuit board is provided with a first power connection line, the first power connection line is connected to the power supply module through the first connector, the first power connection line is further connected to each of the second power supply lines through the second connector.

Abstract: 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.
