Abstract
A touch sensor includes first touch cells disposed in a first touch sensing area, the first touch cells each including a first touch pattern and a first dummy pattern, and second touch cells disposed in a second touch sensing area, the second touch cells each including a second touch pattern and a second dummy pattern. An area of a first dummy pattern area in which the first dummy pattern is disposed is greater than an area of a second dummy pattern area in which the second dummy pattern is disposed.
Claims23
A touch sensor, comprising:
- first touch cells disposed in a first touch sensing area, the first touch cells each including a first touch pattern and a first dummy pattern that is disposed within a first dummy pattern area;
- and
- second touch cells disposed in a second touch sensing area, the second touch cells each including a second touch pattern and a second dummy pattern that is disposed within a second dummy pattern area,
- wherein a fingerprint sensor overlaps the second touch sensing area but not the first touch sensing area,
- wherein an area of the first touch sensing area is greater than an area of the second touch sensing area, and
- wherein an area of the first dummy pattern area in the first touch sensing area that does not overlap the fingerprint sensor is greater than an area of the second dummy pattern area in the second touch sensing area that overlaps the fingerprint sensor.
