Abstract

A touch panel includes: a substrate having a touch recognition area and a fingerprint recognition area; a plurality of first sensing electrodes in the touch recognition area on the substrate; and a first connection electrode connecting adjacent ones of the first sensing electrodes in a first direction. A portion of the first connection electrode adjacent to the fingerprint recognition area is bent along an edge of the fingerprint recognition area.

Claims (31)

1. A touch panel comprising:

a substrate having a touch recognition area and a fingerprint recognition area;

a plurality of first sensing electrodes in the touch recognition area on the substrate; and

a first connection electrode connecting adjacent ones of the first sensing electrodes in a first direction,

wherein a portion of the first connection electrode adjacent to the fingerprint recognition area is bent along an edge of the fingerprint recognition area, and

wherein the adjacent ones of the first sensing electrodes comprise a first-first sensing electrode and a first-second sensing electrode spaced apart from each other, and

the fingerprint recognition area is positioned between the first-first sensing electrode and the first-second sensing electrode,

the first connection electrode connects the first-first sensing electrodes to the first-second sensing electrode.

2. The touch panel as claimed in claim 1 , further comprising:

a plurality of second sensing electrodes in the touch recognition area on the substrate, the plurality of second sensing electrodes insulated from the first sensing electrodes; and

a second connection electrode connecting adjacent ones of the second sensing electrodes in a second direction intersecting the first direction.

3. The touch panel as claimed in claim 2 , wherein a portion of the second connection electrode adjacent the fingerprint recognition area is bent along the edge of the fingerprint recognition area.

4. The touch panel as claimed in claim 2 , wherein the first sensing electrode and the second sensing electrode have at least one of: a quadrangular shape, a triangular shape, a lozenge shape, a circular shape, an elliptical shape, a semicircular shape, or polygonal shape.

5. The touch panel as claimed in claim 2 , wherein the fingerprint recognition area is surrounded by the first sensing electrode and the second sensing electrode.

6. The touch panel as claimed in claim 1 , wherein the fingerprint recognition area has at least one of: a quadrangular shape, a triangular shape, a lozenge shape, a circular shape, an elliptical shape, a semicircular shape, or polygonal shape.

7. The touch panel as claimed in claim 1 , wherein the fingerprint recognition area has an area equal to integer multiples of an area of the first sensing electrode.

8. The touch panel as claimed in claim 1 , wherein the first sensing electrode has an area in a range of 3 square millimeters (mm2) to 30 mm2.

9. The touch panel as claimed in claim 1 , wherein the fingerprint recognition area is positioned in at least one edge portion of the substrate.

10. The touch panel as claimed in claim 1 , wherein the plurality of first sensing electrodes comprises a first-third sensing electrode and a first-fourth sensing electrode which are adjacent to the fingerprint recognition area, and

wherein the first connection electrode comprises a first portion substantially parallel to an edge of the first-third sensing electrode and a second portion substantially parallel to an edge of the first-fourth sensing electrode of the adjacent ones of the first sensing electrodes.

11. A display device comprising:

a display panel comprising a plurality of pixels for displaying an image;

a touch panel on the display panel, the touch panel comprising:

a plurality of first sensing electrodes in a touch recognition area on the display panel; and

a first connection electrode connecting adjacent ones of the first sensing electrodes in one direction; and

a cover glass on the first sensing electrode,

wherein a portion of the first connection electrode adjacent to a fingerprint recognition area is bent along an edge of the fingerprint recognition area, and

wherein the adjacent ones of the first sensing electrodes comprise a first-first sensing electrode and a first-second sensing electrode spaced apart from each other, and

the fingerprint recognition area is positioned between the first-first sensing electrode and the first-second sensing electrode,

the first connection electrode connects the first-first sensing electrodes to the first-second sensing electrode.

12. The display device as claimed in claim 11 , wherein the cover glass has a groove in an area corresponding to the fingerprint recognition area.
