Driving circuit, driving method thereof and display device

A driving method of a driving circuit, the driving circuit comprising a driving unit and a storage unit coupled to the driving unit, wherein the driving method comprises:

• receiving an original signal of an image of a current frame, and converting the original signal of the image of the current frame into image data of the current frame;
• comparing the image data of the current frame with image data of a previous frame cached in the storage unit;
• when the image data of the current frame is consistent with the image data of the previous frame, driving, by the driving unit, a display panel to display an image of the previous frame;
• when the image data of the current frame is not consistent with the image data of the previous frame, driving, by the driving unit, the display panel to display an image of the current frame,
• wherein the storage unit comprising a first storage subunit and a second storage subunit, and the step of comparing the image data of the current frame with image data of a previous frame cached in the storage unit comprises:
• comparing the image data of the current frame and the image data of the previous frame cached in the first storage subunit;
• and
• when the image data of the current frame is consistent with the image data of the previous frame, caching the image data of the current frame into the first storage subunit to overwrite the image data cached in the first storage subunit, reading the cached image data of the previous frame from the second storage subunit, converting the read image data of the previous frame into an output signal, and outputting the output signal to the display panel such that the display panel displays the image of the previous frame.
