In some alternative embodiments, referring to FIG. 6, FIG. 6 is a further cross-sectional view taken along line A-A' of FIG. 1. The ith first sub-electrostatic protection layer 50 and the jth first sub-shading layer 40 are formed in the same layer in the same process, wherein i, j and M are positive integers, i is greater than or equal to 1 and is less than or equal to N, and j is greater than or equal to 1 and is less than or equal to M.

As can be seen from fig. 7, each of the first sub-light-shielding layers 40 includes a light-transmitting hole 41, and this arrangement can limit the reflected light from the fingerprint ridge or fingerprint valley to only propagate in the collimating hole and reach the light-sensing element 13 in the detection area, that is, the first sub-light-shielding layers 40 each include a light-transmitting hole 41 to prevent the reflected light from the adjacent fingerprint ridge or fingerprint valley from reaching the light-sensing element 13 and causing interference. The first light-shielding layer 4 of the present invention can be used in combination with a light-shielding layer for forming light-transmitting holes, and the material of each of the first sub-light-shielding layers 40 can be the same. Of course, other layers, not shown, may be included in the array substrate 2.
In this embodiment, the first sub-shielding layer 40 may be reused as an existing film layer in the display panel with the fingerprint identification function, and when at least one of the N first sub-electrostatic protection layers 50 and the first shielding layer 4 are formed by the same material, the manufacturing process can be simplified, and the display panel can be thinned.
In some alternative embodiments, referring to fig. 8 and 9, fig. 8 is a further cross-sectional view taken along a-a 'of fig. 1, and fig. 9 is a further cross-sectional view taken along a-a' of fig. 1. The array substrate 2 comprises a second substrate 14, a second electrostatic protection layer 15 and at least one photosensitive element 13, wherein the second electrostatic protection layer 15 and the photosensitive element 13 are positioned on one side of the second substrate 14 close to the color film substrate 1;
the second electrostatic protection layer 15 is positioned in the non-display area BB, and the second electrostatic protection layer 15 and the first electrostatic protection layer 5 are at least partially overlapped in an orthographic projection perpendicular to the plane of the first substrate 3;
the second electrostatic protection layer 15 includes a P-layer second sub-electrostatic protection layer 150, where P is greater than or equal to 1 and P is a positive integer.
Fig. 8 and 9 only schematically show the case where the second electrostatic protection layer 15 has two second sub-electrostatic protection layers 150, namely, a 1 st second sub-electrostatic protection layer 150a and a 2 nd second sub-electrostatic protection layer 150b which are nearest to the second substrate 14, wherein in an orthogonal projection perpendicular to the plane of the first substrate 3, the 1 st second sub-electrostatic protection layer 150a, the 2 nd second sub-electrostatic protection layer 150b and the first electrostatic protection layer 5 are overlapped, and the number of layers of the second sub-electrostatic protection layers 150 is not specifically limited here.
Of course, the second electrostatic protection layer 15 may be disposed on the same layer as the photosensitive element 13 or on a different layer, and this embodiment only shows the case where the second electrostatic protection layer 15 is not disposed on the same layer as the photosensitive element 13.
It is understood that static electricity can also enter the display area AA through the array substrate 2, and in the embodiment, the second electrostatic protection layer 15 is disposed in the non-display area BB corresponding to the array substrate 2, so as to prevent static electricity from entering the display area AA from the array substrate 2.
In a direction perpendicular to the plane of the first substrate base plate 3, fig. 8 shows that the 1 st second sub-electrostatic protection layer 150a overlaps the 1 st first sub-electrostatic protection layer 50a, and the 2 nd second sub-electrostatic protection layer 150b overlaps the 2 nd first sub-electrostatic protection layer 50b, the 3 rd first sub-electrostatic protection layer 50c, and the 4 th first sub-electrostatic protection layer 50 d; it can be understood that static electricity is most likely to enter the display area AA from the film layer closest to the first substrate base plate 3 or from the film layer closest to the second substrate base plate 14, and the 1 st layer first sub-electrostatic protection layer 50a has the first main body portion 6 and the first additional portion 7, so that the 1 st layer second sub-electrostatic protection layer 150a overlaps the 1 st layer first sub-electrostatic protection layer 50a, static electricity can be prevented from entering the display area AA from the 1 st layer first sub-electrostatic protection layer 50a and the 1 st layer second sub-electrostatic protection layer 150a, and static electricity that has been generated can be dissipated.

Of course, since the second additional portion 22 includes a plurality of second hollow-out regions, the second hollow-out regions are disposed to further block static electricity from entering the display area AA.

In the corresponding positions of the second sub non-display area a 71b and the second sub non-display area b 72b, because the distance from the ultra-low resistance conductive metal such as silver paste is far, static electricity can easily enter the display panel from the two areas, and in this embodiment, the third hollow-out area 81 is arranged on one side of the first hollow-out area 8 close to the first main body part 6, so that the path of the static electricity entering the display area is further blocked, and the static electricity protection capability is improved.
In some alternative embodiments, the film arrangement of the third hollow-out area 81 may have the following conditions:
