Fingerprint identification structure and method for fabricating the same

A method for fabricating a fingerprint identification structure, comprising:

• forming a plurality of first touch control electrodes and a plurality of second touch control electrodes on a substrate, wherein the plurality of first touch control electrodes and the plurality of second touch control electrodes intersect with each other;
• and
• forming a plurality of photo-sensitive patterns on the substrate,
• wherein the plurality of photo-sensitive patterns are disposed at intersections of the plurality of first touch control electrodes and the plurality of second touch control electrodes, respectively, and are configured to separate the plurality of second touch control electrodes from the plurality of first touch control electrodes;
• forming of the second touch control electrodes comprises:
• depositing a transparent conductive material on the substrate on which the plurality of photo-sensitive patterns are formed, and patterning the transparent conductive material to form first parts, which covers the photo-sensitive patterns, of the second touch control electrodes;
• and
• depositing a second electrode material on the substrate, and patterning the second electrode material to obtain second parts, which do not cover the photo-sensitive patterns, of the second touch control electrodes, wherein the first parts electrically connect with the second parts to form the second touch control electrodes together.

• a substrate;
• a plurality of first touch control electrodes and a plurality of second touch control electrodes, which are provided on the substrate, wherein the plurality of first touch control electrodes and the plurality of second touch control electrodes intersect with each other;
• and
• a plurality of photo-sensitive patterns, which are disposed at intersections of the plurality of first touch control electrodes and the plurality of second touch control electrodes, respectively, and are configured to separate the plurality of second touch control electrodes from the plurality of first touch control electrodes,
• wherein the plurality of second touch control electrodes are provided on a side, which is away from the substrate, of the plurality of first touch control electrodes;
• the second touch control electrodes comprise first parts covering the photosensitive patterns and second parts not covering the photo-sensitive patterns, and at least first parts are made of a transparent conductive material;
• the first parts are made of ITO, and the second part are made of metal;
• each of the photo-sensitive patterns with one of the first touch control electrodes and one of the second touch control electrodes, which are separated from each other by the each of the photo-sensitive patterns, form a photodiode;
• and
• the first parts and the second parts are electrically connected by lap joints or through-holes.
