Abstract: A display panel driving method, a display panel and a display apparatus. The display panel driving method comprises: according to a data signal transmitted in a data line, determining whether a grayscale value difference of a data signal input by a pixel unit of an nth row and a data signal input by a pixel unit of an (n−1)th row is greater than a threshold, n being a positive integer less than or equal to N; if the grayscale value difference between the data signal input by the pixel unit of the nth row and the data signal input by the pixel unit of the (n−1)th row is greater than the threshold, then adjusting the phase of a clock signal input by the nth shift register, such that the falling of the pull-up node of the nth shift register is delayed along with time, to output a phase-delayed scan signal.
