Claim:
1. An in-cell touch panel, comprising: a substrate, a plurality of self-capacitance electrodes located on the substrate and arranged in an array, and a touch sensing unit for determining the touch position by sensing capacitance value changes on the self-capacitance electrodes, the self-capacitance electrodes being electrically connected to the touch sensing unit via wires including a first wire and a second wire; wherein the array of the self-capacitance electrodes comprises a first column of self-capacitance electrodes and a second column of self-capacitance electrodes arranged in alternation, the number of elements in each column of self-capacitance electrodes is n and there is a submultiple m of n, wherein n and m are both positive integers and n is greater than 1, and the first column of self-capacitance electrodes includes n/m groups of self-capacitance electrodes divided in the sequence of column adjacency, each group includes m self-capacitance electrodes and the self-capacitance electrodes in the same group are electrically connected by the same first wire; the second column of self-capacitance electrodes include m groups of self-capacitance electrodes, each group includes n/m self-capacitance electrodes and the self-capacitance electrodes in the same group are electrically connected by the same second wire; wherein n/m self-capacitance electrodes in the same group in the second column of self-capacitance electrodes are respectively formed by self-capacitance electrodes, in the second column of self-capacitance electrodes, which are in row adjacency with the self-capacitance electrodes of different groups in the first column of self-capacitance electrodes.
