Abstract
A fingerprint identification electrode includes a first conductive layer, a second conductive layer, and an insulating layer between the first conductive layer and the second conductive layer. The first conductive layer includes a plurality of first touch electrode strips. The second conductive layer includes a plurality of second touch electrode strips and a plurality of dummy electrodes. The first touch electrode strips and the second touch electrode strips intersect. The second touch electrode strips are separated from the dummy electrodes. A part of each of the first touch electrode strips that is located between any two adjacent second electrode strips overlaps at least one of the dummy electrodes.
