In-cell touch panel, touch detection method and display device
An in cell touch panel, a touch detection method and a display device. The in-cell touch panel comprises: a substrate, a plurality of self-capacitance electrodes located on said 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 number of elements in each column of self-capacitance electrodes is n and there is a submultiple m of n, and a 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 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 a second wire.
