Driving method of display device and driving device

A driving device of a display device, comprising:

• a strong light detection device, configured to:
• in response to determining that the display device enters a low power consumption state, control a light intensity detection component to detect in real time whether the display device is in a strong light environment;
• a first frequency adjustment device, configured to:
• in response to the light intensity detection component determining that the display device is in the strong light environment, control a driver chip to adjust a picture refresh frequency to a first frequency;
• and
• a second frequency adjustment device, configured to:
• in response to the light intensity detection component determining that the display device is in a non-strong light environment, determine a current gray scale of the display device according to a latest instruction set by a user, determine an optimal refresh frequency according to the current gray scale and a corresponding relationship between a preset gray scale and the optimal refresh frequency, and control the driver chip to adjust the picture refresh frequency to the optimal refresh frequency;
• wherein the first frequency and the optimal refresh frequency each are smaller than a picture refresh frequency of the display device in a normal display state.
