wherein the touch panel further comprises a display film layer provided with a plurality of illuminating sub-pixels arranged in an array;

wherein the display film layer is further provided with at least one blank sub-pixel, the at least one blank sub-pixel being arranged in the illuminating sub-pixels of the display film layer, the fingerprint identification film layer comprising at least one second fingerprint identification pattern; and

wherein an orthographic projection of the second fingerprint identification pattern on the touch film layer overlaps with an orthographic projection of the blank sub-pixel on the touch film layer.

2. The touch panel according to claim 1 , wherein the orthographic projection of the fingerprint identification film layer on the touch film layer does not overlap with an orthographic projection of the illuminating sub-pixels on the touch film layer.

3. The touch panel according to claim 2 , wherein the fingerprint identification film layer comprises at least one first fingerprint identification pattern;

an orthographic projection of the first fingerprint identification pattern on the touch film layer is located at a gap of an orthographic projection of adjacent illuminating sub-pixels on the touch film layer.

4. The touch panel according to claim 2 , further comprising lead lines connecting the fingerprint identification film layer, wherein an orthographic projection of the lead lines on the touch film layer does not overlap with an orthographic projection of the illuminating sub-pixels on the touch film layer.

5. The touch panel according to claim 2 , wherein a width of a gap between adjacent illuminating sub-pixels ranges from 10 μm to 50 μm; and a width of a fingerprint driving electrode and a fingerprint inductive electrode is within the range of the width of the gap.

6. The touch panel according to claim 1 , wherein the display film layer is provided with a plurality of blank sub-pixels, and the plurality of blank sub-pixels are evenly distributed between the illuminating sub-pixels.
