Abstract

A display module includes a display panel, a power supply driver, a voltage signal line, a sampling resistor and a detection and control circuit. The voltage signal line is connected between the display panel and the power supply driver. The sampling resistor is connected in series with the voltage signal line. The detection and control circuit is connected to two ends of the sampling resistor and the power supply driver. The detection and control circuit is configured to: detect a voltage across the sampling resistor or a current flowing through the sampling resistor; and control the power supply driver to generate a driving voltage equal to a preset value lower than a voltage threshold, if determining that the voltage across the sampling resistor is greater than or equal to the voltage threshold, or if determining that the current is greater than or equal to a current threshold.
