摘要: The present disclosure discloses a driving apparatus of a display panel and a display apparatus. A temperature detection module for detecting a temperature of the switching power supply is provided, so that when the temperature of the switching power supply is larger than or equal to a preset temperature value, the temperature detection module may feed back to the clock controller a first control signal. The clock controller may switch a polarity inversion mode of displaying an image on the display panel according to the received first control signal, i.e., switching the polarity inversion mode from the first polarity inversion mode with a large power consumption into a second polarity inversion mode with a small power consumption, thereby reducing the power consumption of the switching power supply and thus reducing the temperature of the switching power supply.
