Patent ID: 8310463

Claim:
A capacitive touch panel comprising: a plurality of first direction electrode strings, wherein a plurality of first electrodes are disposed on each of the first direction electrode strings; a plurality of second direction electrode strings, wherein a plurality of second electrodes are disposed on each of the second direction electrode strings, and each of the second electrodes is disposed between the first electrodes of the adjacent first direction electrode strings, the closest distance between the first electrode and the adjacent first electrode ranges from 10-100 micrometers; and a dielectric layer disposed between the first direction electrode strings and the second direction electrode strings; wherein the width of the first electrode decreases from middle of the first electrode to two sides of the first electrode, each of the first electrodes includes a perimeter, and a quarter of the perimeter closest to and facing a quarter of a perimeter of the second electrode has a first slope change rate and a different second slope change rate, the quarter of the perimeter of the first electrode includes a first line segment and a second line segment, the first line segment and the second line segment are not parallel to the quarter of the perimeter of the corresponding second electrode; a first distance between the first line segment of the quarter of the perimeter of the first electrode and the nearest quarter of the perimeter of the adjacent second electrode varies as a line segment of the quarter of the perimeter of the second electrode extends; a second distance between the second line segment of the quarter of the perimeter of the first electrode and the nearest quarter of the perimeter of the adjacent second electrode varies as a line segment of the quarter of the perimeter of the second electrode extends; the first distance and the second distance have different change rate.
