CAPACITIVE TOUCH SENSOR, MANUFACTURING METHOD OF THE SAME AND CAPACITIVE TOUCH PANEL INCLUDING THE SAME

摘要

The present invention relates to a capacitive touch sensor, and the capacitive touch sensor comprises a circuit board in which a plurality of tunnels is formed; a first electrode pattern including a plurality of first electrode pattern elements extended and formed toward one upper surface of the circuit board by patterning a conductive layer formed by drying conductive liquid after deeply coating the conductive layer with the conductive liquid; and a second electrode pattern including a plurality of second electrode pattern elements intersecting with the first electrode pattern. The first electrode pattern elements are electrically connected from each other using a first electrode pattern connection unit formed on the circuit board. The second electrode pattern elements are electrically connected from each other using a second electrode pattern connection unit formed in the tunnel of the circuit board. The capacitive touch sensor is unnecessary to form a bridge electrode pattern exposed to the outside and may maintain good exterior by electrically connecting the electrode pattern elements using the tunnel formed inside the circuit board. The capacitive touch sensor has a beneficial effect capable of improving productivity by electrically connecting the electrode pattern elements with a simple process and reducing manufacturing time. Therefore, the capacitive touch sensor is effectively used for a capacitive touch panel.
