摘要： A driving circuit, a driving method thereof and a display device including the driving circuit are disclosed. The driving circuit includes a driving unit and a storage unit coupled to the driving unit. The storage unit caches image data. The driving unit receives an original signal of an image of a current frame, converts the original signal of the image of the current frame into image data of the current frame, and compares 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, a display panel displays an image of the previous frame, and when the image data of the current frame is not consistent with the image data of the previous frame, the display panel displays an image of the current frame.
