The touch panel comprises multiple touch patterns which are arranged in an array manner, wherein each touch pattern comprises a first transmitting electrode, a second transmitting electrode and multiple receiving electrodes, the second transmitting electrode is parallel to the first transmitting electrode, the receiving electrodes are configured between the first transmitting electrode and the second transmitting electrode and are adjacent to the first transmitting electrode and the second transmitting electrode respectively; the first transmitting electrodes, the second transmitting electrodes and the receiving electrodes are not overlapped, the first transmitting electrodes of the touch patterns are not connected, and the second transmitting electrodes of the touch patterns are not connected.

Description

technical field [0001] The present invention relates to a touch panel, and in particular to a capacitive touch panel and an electrode configuration method thereof. Background technique [0002] With the vigorous development of touch technology, touch devices such as mobile phones, notebook computers or tablet computers are welcomed by consumers and bring huge business opportunities due to the intuitive operation and input interface provided. Among them, touch devices can be classified into capacitive touch and resistive touch according to different touch sensing methods, and the advantage of capacitive touch is that it has relatively high sensitivity and long service life. [0003] Capacitive touch is mainly to use conductive touch media to touch the touch panel, so as to establish additional capacitance on the corresponding electrodes, so that the equivalent capacitance of the touch electrodes changes. Then, the sensor circuit (sensor IC) at the back end can judge the touc...
