Electrode structure and capacitance sensor having the same

摘要

Provided is an electrode structure for use with a capacitive touch panel to enhance capacitance sensing capability thereof. The electrode structure includes electrically conductive fine lines each forming fine line portions, sensing portions, and cross portions. The fine line portions, the sensing portions, and the cross portions together form a latticed pattern. The sensing portions are each disposed between two adjacent ones of the cross portions. Two ends of each said sensing portion are connected to two said cross portions through two fine line portions, respectively. The sensing portions each have a geometric configuration with a short axis and a long axis. The long axis extends in the direction of a corresponding one of the fine line portions. The short axis is of a width larger than a corresponding one of the fine line portions.
