Abstract
A touch screen panel including a substrate having an effective area and a pad area, sensing electrodes disposed in the effective area, pads disposed in the pad area, wirings connecting the sensing electrodes and the pads, respectively, the wirings each having different lengths, and an electrostatic dispersion pad disposed adjacent to a sensing electrode disposed closest to the pad area among the sensing electrodes.
Claims17
An organic light emitting diode display panel, comprising:
- a first substrate comprising an organic light emitting diode;
- an encapsulation layer encapsulating the organic light emitting diode;
- a first sensing electrode disposed on the encapsulation layer;
- a first pad;
- and
- a first wiring electrically connecting the first sensing electrode to the first pad,
- wherein the first substrate further comprises:
- an effective area where organic light emitting diode and the first sensing electrode are disposed;
- a pad area where the first pad is disposed;
- and
- a stepped portion disposed between the effective area and the pad area,
- wherein at least a portion of the first wiring is disposed on the stepped portion and has a step along the stepped portion while connecting the first sensing electrode to the first pad, and
- wherein the stepped portion and the pad area comprise layers formed in an area outside the effective area, and the first pad overlaps at least one of the layers, and
- wherein the at least a portion of the first wiring disposed on the stepped portion is disposed at a lower elevation than the first pad with respect to the first substrate, and the first sensing electrode is disposed at a lower elevation than the first pad with respect to the first substrate.

A touch screen panel, comprising:
- a substrate comprising an effective area, a pad area disposed outside the effective area, and a stepped portion disposed between the effective area and the pad area;
- a first sensing electrode disposed in the effective area;
- a first pad disposed on the pad area;
- and
- a first wiring connecting the first sensing electrode to the first pad, the first wiring having a first width and longitudinally extending in a first direction, the first width is measured from a first end and a second end of the first wiring in a second direction intersecting the first direction,
- wherein:
- the first wiring comprises a first extension having a second width, the second width measured from a first end and a second end of the first extension in the second direction;
- the second width of the first extension is greater than the first width of the first wiring;
- and
- the first extension protrudes outwardly from the first wiring in the second direction and covers a side of the stepped portion on which the first pad is disposed.
