Abstract
Disclosed is a conductor pattern structure of a capacitive touch panel. The structure contains two conductor assemblies with different directions, and each conductor assembly includes a number of conductive cells that are interconnected by conduction lines. Conductor assemblies with different directions are separated by an insulating material. An electrical field and induced capacitors are generated between adjacent conductor assemblies with different directions when giving control signals. Then the touched location is detected. The capacitive induced layer structure also contains a number of floating induced cells, distributed among the adjacent conductive cells. The floating induced cells generate new induced capacitors without connecting to any conduction lines and requiring any control signals. Therefore, the structure has advantages of improving the distribution of the electrical field and enlarging the touch sensing area.
