Display substrate and short-circuit detecting method thereof, and display device

A display device comprising a display substrate, the display substrate comprising:

• a plurality of touch control electrodes in a display area;
• a plurality of touch control signal lines, each of the touch control signal lines connecting one of the touch control electrodes to a peripheral circuit area of the display substrate;
• a voltage receiving end located in the peripheral circuit area;
• and
• a plurality of switch circuits located in the peripheral circuit area, each of the switch circuits being connected to the voltage receiving end, and each of the switch circuits being respectively connected with a switch control signal;
• wherein the plurality of touch control electrodes are divided into a plurality of test groups, and each of the touch control electrodes belongs to one of the plurality of test groups, and
• each of the switch circuits is connected to all of the touch control electrodes in one of the test groups through the touch control signal line, and the switch circuit is configured to:
• switch a connection state between each of the connected touch control electrodes and the voltage receiving end under the control of the connected switch control signal.
