Abstract
Disclosed is a touch screen panel including a plurality of separate sensing electrodes, and a plurality of separate driving electrodes. Each of the sensing electrodes includes a main electrode and a plurality of expanded parts. Each of the expanded parts includes a sub-electrode extending from the main electrode and at least one expanded electrode extending from the sub-electrode. Each of the driving electrodes surrounds at least part of a corresponding one of the expanded parts.
Claims20
A touch screen panel comprising:
- a plurality of separate sensing electrodes;
- a plurality of separate driving electrodes;
- and
- a flexible printed circuit having a bonding region, a via region in an area of the flexible printed circuit separate from the bonding region, and a plurality of traces thereon configured to electrically connect bond pads in the bonding region to a touch screen controller,
- wherein:
- each of the sensing electrodes comprises a main electrode and a plurality of expanded parts,
- each of the expanded parts comprises (i) a sub-electrode expanding or extending from the main electrode and (ii) at least one expanded electrode expanding or extending from the sub-electrode, and
- each of the driving electrodes surrounds at least part of a corresponding one of the expanded parts.
The touch screen panel according to claim 15, wherein line widths of the second wiring lines increase as distances between the second wiring lines and the driving electrodes increase.
