Abstract: A display substrate, a display module and a control method are provided in the present disclosure. The display substrate includes a first substrate and a second substrate. The first substrate includes a base substrate, conductive pads, a first switch unit group electrically connected to the conductive pads and signal wires, and a second switch unit group electrically connected to the conductive pads. The display substrate includes a substrate detection phase where all second switch units are cutoff, all first switch units are conducting, and an external detection device input a first detection signal to the substrate through the conductive pads and all first switch units. When the first switch unit group is conducting, the conductive pads are used for substrate detection, and when the second switch unit group is cutoff, the conductive pads in a same pad region are connected each other to be multiplexed as electrostatic conductive pads.
