Abstract

A drive circuit and a display device are provided. A detection diode is included in a drive chip of the drive circuit. An acquisition circuit may acquire an electrical signal related to a voltage across the detection diode and a current flowing through the detection diode. A detection circuit may obtain an internal temperature of the drive chip based on the electrical signal acquired by the acquisition circuit. A control circuit may control the drive chip based on the internal temperature of the drive chip obtained by the detection circuit. When the detecting circuit detects that the internal temperature of the drive chip is greater than a maximum threshold temperature or less than a minimum threshold temperature, the acquisition circuit controls the drive chip to stop outputting a drive signal.
