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.

Abstract: A touch substrate is disclosed, which comprises a substrate, an insulating layer, a first touch electrode, and a second touch electrode. The insulating layer is arranged on the substrate. The first and second touch electrodes are arranged on the substrate, have an overlapping region, and are insulated from each other in the overlapping region through the insulating layer. The substrate is provided with a first trench, in which the first touch electrode is at least partially arranged. By arranging the first touch electrode at least partially in the first trench, the difference in height due to the first touch electrode is reduced or eliminated, and adverse effects on films over the first touch electrode due to the difference in height are reduced or eliminated. A method for fabricating the touch substrate and a touch panel are also disclosed.
