Abstract
A touch screen apparatus includes: an active area and a non-active area outside the active area; first sensing electrodes arranged along a first direction in the active area; second sensing electrodes arranged along a second direction intersecting the first direction in the active area, the second sensing electrodes being insulated from the first sensing electrodes; and at least one additional sensing electrode separated from the first and second sensing electrodes, the at least one additional sensing electrode being located in the non-active area.
Claims15
A touch screen apparatus comprising:
- a first substrate having an active area and a non-active area outside the active area;
- a second substrate spaced from the first substrate by a seal member;
- first sensing electrodes arranged along a first direction in the active area;
- second sensing electrodes arranged along a second direction intersecting the first direction in the active area, the second sensing electrodes being insulated from the first sensing electrodes;
- at least one first additional sensing electrode arranged along the first direction in the non-active area, and separated from the first and second sensing electrodes;
- at least one second additional sensing electrode arranged along the second direction in the non-active area, and separated from the first and second sensing electrodes, the at least one second additional sensing electrode overlapping with the seal member;
- and
- connection lines connecting each of the first sensing electrodes, the second sensing electrodes, the at least one first additional sensing electrode, and the at least one second additional sensing electrode to a touch controller,
- wherein a portion of the at least one first additional sensing electrode overlaps with a portion of at least one of the connection lines, and an insulating layer is provided between the portion of the at least one first additional sensing electrode and the connection lines which overlap each other.
