Claim:
1. A driving apparatus of a display panel, comprising: a clock controller configured to control a polarity inversion mode of displaying an image on the display panel; a switching power supply configured to supply power to the clock controller; and a temperature detection module electrically connected to the clock controller and configured to detect a temperature of the switching power supply and compare the detected temperature of the switching power supply with a preset temperature value, and when the detected temperature of the switching power supply is larger than or equal to the preset temperature value, transmit a first control signal to the clock controller; wherein the clock controller is further configured to receive the first control signal, and switch the polarity inversion mode of displaying the image on the display panel from a first polarity inversion mode to a second polarity inversion mode according to the received first control signal, wherein a power consumption of the switching power supply in the second polarity inversion mode is smaller than a power consumption of the switching power supply in the first polarity inversion mode; wherein the temperature detection module comprises: wherein, when the temperature of the switching power supply detected by the thermistor is larger than or equal to the preset temperature value, a resistance value of the thermistor is larger than or equal to a preset resistance value, and then the control signal output terminal outputs a first control signal; and when the temperature of the switching power supply detected by the thermistor is smaller than the preset temperature value, the resistance value of the thermistor is smaller than the preset resistance value, and then the control signal output terminal outputs a second control signal so as to switch the polarity inversion mode of displaying the image on the display panel from the second polarity inversion mode to the first polarity inversion mode.
