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.

Abstract: Provided are a shift register, a gate drive circuit, a display panel and a driving method. The shift register includes a first output module, a second output module, a first node, a second node, a first power supply signal terminal, a first clock signal terminal and a scan output terminal. The first output module and the second output module are electrically connected to the scan output terminal. The first output module is further electrically connected to the first power supply signal terminal and the first node. The first node is configured to control a conduction state of the first output module. The second output module is further electrically connected to the first clock signal terminal and the second node. The second node is configured to control a conduction state of the second output module. There is no capacitor in the first output module and/or the second output module.

Abstract: Disclosed are a display panel and a display device. In some embodiments of the disclosure, opening support structures are arranged between a first substrate and a second substrate in at least a sub-area corresponding to the largest one of respective first spacings, that is, the opening support structures are arranged in at least the sub-area in which connection segments of touch signal lines are the most sparsely arranged.
