The present invention relates to a capacitive touch panel device of a high-sensitivity digital system. The capacitive touch panel device of a high sensitivity digital system according to the present invention includes a substrate, a display area formed at the center of the substrate to display images, a non-active area formed along the outer periphery of the display area, extending to the end of the substrate, and mounted with a plurality of signal transmitting wire electrodes, two pairs of position sensing main sensor electrodes arranged in a two-dimensional fashion in the display area to display coordinates, a plurality of bridge electrodes interposed between the two pairs of position-sensing main sensor electrodes such that the two pairs of position-sensing main sensor electrodes are electrically connected in each direction, an external terminal unit electrically connected to the ends of the plurality of signal transmitting wire electrodes the other ends of which are connected to the two pairs of position-sensing main sensor electrodes, and a position sensing sub electrode electrically connected to each of the two pairs of position-sensing main sensor electrodes, and arranged in the direction different from the direction wherein the bridge electrodes are connected. Whereby, the present invention can be employed in a large size touch panel device without increasing the number of input/output signal transmitting wire electrodes, and may sense an accurate position of coordinates in the touch panel apparatus at the same time. Therefore, the present invention saves space owing to the reduced number of signal transmitting wire electrodes under the condition of the same number of position-sensing main sensor electrodes, thereby providing a capacitive touch panel device of a digital system with the advantages of being lightweight and having a slim size. |
