CAPACITIVE TOUCH STRUCTURE, IN-CELL TOUCH PANEL, DISPLAY DEVICE AND SCANNING METHOD THEREOF

摘要

A capacitive touch structure, an in-cell touch panel, a display device and a scanning method thereof are disclosed. The capacitive touch structure includes: self-capacitance electrodes; block electrodes disposed in the same layer as self-capacitance electrodes; first wires connected with self-capacitance electrodes; second wires connected with block electrodes; and a touch sensing chip connected with the first wires and the second wires. There are at least adjacent self-capacitance electrodes that satisfy the following conditions: at least two block electrodes are provided between any two adjacent self-capacitance electrodes each of which corresponds to one self-capacitance electrode; block electrodes of one self-capacitance electrode are connected with the same second wire, block electrodes of adjacent self-capacitance electrodes are connected with different second wires, and one second wire is connected with block electrodes of at least two self-capacitance electrodes.
