Touch display device having fingerprint recognition function

A touch display device, comprising:

• a display panel and a touch recognition module;
• and
• a driver module;
• wherein the touch recognition module comprises a first electrode layer disposed on the display panel, an insulating layer disposed on both the first electrode layer and the display panel, and a second electrode layer disposed on the insulating layer;
• wherein the first electrode layer comprises a plurality of first touch electrodes spaced apart from each other and a first touch connecting line, and the second electrode layer comprises a touch area and a fingerprint recognition area adjacent to the touch area, a second touch connecting line, and a plurality of fingerprint connecting lines, wherein the touch area comprises a plurality of second touch electrodes spaced apart from each other, and the fingerprint recognition area comprises a plurality of fingerprint recognition electrodes arranged in an array, wherein the first touch electrodes are electrically connected to the driver module through the first touch connecting line, the second touch electrodes are electrically connected to the driver module through the second touch connecting line, and each of the fingerprint recognition electrodes is electrically connected to the driver module through one of the fingerprint connecting lines;
• wherein the first touch connecting line is electrically connected to the driving module after being changed to the second electrode layer through a via hole extending through the insulating layer;
• and
• wherein during touch sensing, the first touch electrodes, the second touch electrodes, and the fingerprint recognition electrodes cooperatively form mutual capacitance for touch detection, and during fingerprint recognition, the fingerprint recognition electrodes form self-capacitance for recognizing a fingerprint.
