Display module and method for driving the same, and display apparatus

A display module, comprising:

• a display panel;
• a power supply driver configured to generate a driving voltage;
• a voltage signal line connected between the display panel and the power supply driver, and configured to transmit the driving voltage generated by the power supply driver to the display panel, so that the display panel emits light;
• a sampling resistor connected in series with the voltage signal line;
• and
• a detection and control circuit connected to two ends of the sampling resistor, and configured to detect a voltage across the sampling resistor or a current flowing through the sampling resistor, wherein
• the detection and control circuit is further connected to the power supply driver, and is further configured to perform any one of controlling the power supply driver to generate a driving voltage equal to a preset value lower than a voltage threshold if the detection and control circuit determines that the voltage across the sampling resistor is greater than or equal to the voltage threshold, and controlling the power supply driver to generate the driving voltage equal to the preset value lower than the voltage threshold if the detection and control circuit determines that the current is greater than or equal to a current threshold.
