Abstract
A self-capacitive touch panel structure includes a touch detection chip and multiple self-capacitance electrodes arranged as a matrix and isolated with each other. Each self-capacitance electrode connected with the touch detection chip through a connection line. Each self-capacitance electrode electrically connected with a corresponding connection line through at least one via hole. A group of connection lines connected with a same column of the multiple self-capacitance electrodes are divided into an odd number group and an even number group. The connection lines in the odd number group are sequentially connected with a terminal of a corresponding self-capacitance electrode of the same column of the self-capacitance electrodes. The connection lines in the even number group are sequentially connected with a terminal of a corresponding self-capacitance electrode of the same column of the self-capacitance electrodes. An in-cell touch panel and a liquid crystal display including above structure are also disclosed.
