More Information
Summary:A capacitive touch screen sensor 104 is disclosed. The sensor 104 comprises an array of drive electrodes 100, an array of sense electrodes 102 separated from the array of drive electrodes by a dielectric layer 200, each sense electrode 102 being offset from each drive electrode 100 to define respective overlapping regions 112 and first non-overlapping regions 113, and a plurality of non-electrically connected electrodes 402, each non-electrically connected electrode 402 being arranged to correspond to each first non-overlapping region 113 and spaced from adjacent drive 100 or sense electrodes 102 by a perimeter gap 404. The perimeter gap 404 may have a width of about 100um or less. A related touch panel and method of fabricating the same are also disclosed.
