Abstract
The present invention relates to the CDA that constitutes the capacitive detection device of the present invention placed on the upper side of the conductor. It aims to narrow the width of the far-distance CDA signal line, which was previously widened to reduce resistance, to be the same as the width of the near-distance signal line. As a result, this reduces the time constant in the far-distance CDA, enhancing the detection speed, and minimizes the width of the Dead Zone caused by the signal line, thereby reducing object detection errors or touch coordinate calculation errors.
