Abstract:
1. A high-sensitivity digital capacitive touch panel device comprising: a substrate; a display area formed on a central region of the substrate to display images; an inactive area formed along an outer periphery of the display area and extending to an end of the substrate, the inactive area having a plurality of signal-transmitting wire electrodes mounted thereon; two pairs of main position sensor electrodes arranged in two dimensions on the display area to display coordinates; a plurality of bridge electrodes disposed between the main position sensor electrodes such that the two pairs of the main position sensor electrodes can be electrically connected to each other in each direction therethrough; an external terminal unit electrically connected to one end of each of the signal-transmitting wire electrodes, the other end of which is electrically connected to the two pairs of the main position sensor electrodes; and a sub position sensor electrode electrically connected to each of the two pairs of the main position sensor electrodes in a different direction than that of the bridge electrodes connected to the main position sensor electrodes.
