Abstract

The application discloses a display panel, a protection method and a display device. The display panel comprises a temperature detection module, which is used for converting a temperature signal of the display panel into an electric signal; a control module, which is connected with the temperature detection module and is used for generating a control signal when the electric signal of the temperature detection module exceeds a preset value; and a protection module, which is connected with the control module and is used for performing overheat protection based on the control signal. The temperature detection module detects the temperature of the display panel by converting the temperature signal of the display panel into the electric signal, and outputs a corresponding control signal based on the result of the electric signal, so that protection control is performed based on the control signal, overheat protection is improved, and the protection effect and the display life of the display panel are improved.
