Specifically, in a direction perpendicular to the first mating surface P101, a plurality of the micro grooves 1011 may have a plurality of different depths L.
Specifically, the micro grooves 1011 may be unit groove bodies (as shown in fig. 7 and 8) arranged in an array; on the first splicing surface P101, the opening shape of the individual micro groove 1011 may be any one of a circle (fig. 7), a rectangle (fig. 8), and a prism.

Specifically, the micro groove 1011 may be formed by laser, CNC processing, acid etching, or the like.
It may be appreciated that, by setting the first splicing surface P101 of the substrate 101 and the second splicing surface P102 of the display functional layer 102 to be flush on the splicing end surface P10 of the display panel 10, setting a plurality of micro grooves 1011 on the first splicing surface P101, at least partially covering the first splicing surface P101 and the second splicing surface P102 with a part of the sealant 103 being disposed in the micro grooves 1011, when the sealant 103 is coated on the side of the multi-Mini LED veneer for sealing, the self gravity of the sealant 103 is counteracted by the adsorption tension of the micro grooves 1011, and the sealant 103 coated on the first splicing surface P101 is tightly adsorbed, so that the problem that the thickness distribution of the sealant 103 after curing is uneven due to the self gravity flowing in the curing process is prevented, the sealing effect of the side surface of the display panel 10 is effectively improved, and the flatness of the seam of the whole machine is also improved.
In one embodiment, the micro grooves 1011 have different depths L in a direction perpendicular to the first mating surface P101.
Specifically, the depth L of the micro groove 1011 is 10um to 100um, and may specifically be any one of 10um, 15um, 22um, 28um, 35um, 47um, 58um, 67um, 82um, and 100 um.
Specifically, the depths L of the plurality of micro grooves 1011 may decrease in sequence in a direction from one side surface of the substrate 101 facing away from the display function layer 102 to the other side surface of the substrate 101 facing toward the display function layer 102.
It can be appreciated that, by setting the micro grooves 1011 to have a plurality of different depths L, the micro grooves 1011 of different depths L have different adsorption capacities with the sealant 103, and since the forming grooves on the side surface of the glass substrate 101 have an effect on the hardness and the impact resistance of the glass substrate 101, the adsorption capacity of the sealant 103 on the first splicing surface P101 can be further improved by reasonably setting the distribution of the micro grooves 1011 of different depths L.
In an embodiment, as shown in fig. 4 and 5, the depth L of the micro grooves 1011 tends to decrease in a direction from one side of the substrate 101 away from the display function layer 102 to the other side of the substrate 101 near the display function layer 102.
Specifically, the plurality of micro grooves 1011 are arranged in an array on the first splicing surface P101, in a direction from a side surface of the substrate 101 facing away from the display function layer 102 to another side surface of the substrate 101 facing closer to the display function layer 102, the plurality of micro grooves 1011 include a plurality of micro groove groups 1011G sequentially arranged, each micro groove group 1011G includes a plurality of micro grooves 1011, and the depth L of the micro groove 1011 in each micro groove group 1011G is the same, the depths L of the micro grooves 1011 in different micro groove groups 1011G are different, and the depth L of the micro groove 1011 in the micro groove group 1011G is smaller as approaching the display function layer 102.
Specifically, in the present embodiment, the shapes and areas of the openings of the micro grooves 1011 in the different micro groove groups 1011G may be equal or may be different, and the shapes and areas of the openings of the micro grooves 1011 in the same micro groove group 1011G may be equal.
Further, as shown in fig. 4, the depth L of the plurality of micro grooves 1011 tends to gradually decrease in a direction from one side surface of the substrate 101 facing away from the display function layer 102 to the other side surface of the substrate 101 facing toward the display function layer 102.
It can be understood that the depth L of the micro groove 1011 far away from the display functional layer 102 is set to be larger, so that the stronger the capability of adsorbing the sealant 103 is, the smaller the depth L of the micro groove 1011 near the display functional layer 102 is, so that the supporting capability of the substrate 101 near the display functional layer 102 is stronger, and the technical scheme of the embodiment can improve the joint integrity of the display panel 10 and enhance the impact resistance of the substrate 101 on the basis of ensuring the thickness uniformity of the sealant 103.
In the above embodiment, the bottom surfaces of the micro grooves 1011 are located on a micro groove depth surface P1011, and the included angle between the micro groove depth surface P1011 and the first splicing surface P101 is 5 ° to 85 °.

θ＝arctan[(D2–D1)/(T1+T2)]；
d2 is the thickness of the bottom of the sealant 103 when the micro groove 1011 is not provided on the first splicing surface P101 under the same condition, D1 is the thickness of the top of the sealant 103, T1 is the thickness of the substrate 101, and T2 is the thickness of the display functional layer 102.
Specifically, the angle θ may be any one of 5 °, 15 °,20 °, 30 °, 36 °,45 °,60 °, 75 °, and 85 °, and specifically may be adjusted according to practical situations.
It can be understood that a plurality of continuous micro grooves 1011 are provided, the plurality of continuous micro grooves 1011 form an angle θ, and the angle of the plurality of micro grooves 1011 is matched with the inclination angle of the film layer with uneven thickness formed after the sealant 103 is actually cured, so that the slotting mode of the micro grooves 1011 is more reasonable, and the coating thickness of the sealant 103 after the subsequent curing is more uniform.
In the above embodiments, as shown in fig. 6, 7, and 8, the opening areas of the micro grooves 1011 tend to decrease in the direction from one side of the substrate 101 away from the display function layer 102 to the other side of the substrate 101 close to the display function layer 102.
Specifically, on the first splicing surface P101, the plurality of micro grooves 1011 may be unit groove bodies arranged in an array; the opening of the micro groove 1011 may be any one of a circle, a rectangle, a triangle, and a prism.
Specifically, the plurality of micro grooves 1011 are arranged in an array on the first splicing surface P101, in a direction from a side surface of the substrate 101 facing away from the display function layer 102 to another side surface of the substrate 101 facing closer to the display function layer 102, the plurality of micro grooves 1011 include a plurality of micro groove groups 1011G sequentially arranged, each micro groove group 1011G includes a plurality of micro grooves 1011, and an opening area of the micro groove 1011 in each micro groove group 1011G is the same, an opening area of the micro groove 1011 in a different micro groove group 1011G is different, and the opening area of the micro groove 1011 in the micro groove group 1011G is smaller as approaching the display function layer 102.
Further, as shown in fig. 6, 7, and 8, the opening areas of the micro grooves 1011 tend to gradually decrease in a direction from one side surface of the substrate 101 facing away from the display function layer 102 to the other side surface of the substrate 101 facing the display function layer 102.
It can be understood that the opening area of the micro groove 1011 far away from the display function layer 102 is larger, so that the stronger the capability of adsorbing the sealant 103, the smaller the opening area of the micro groove 1011 near the display function layer 102, so that the supporting capability of the substrate 101 near the display function layer 102 is stronger, the technical scheme of the embodiment can improve the joint integrity of the display panel 10 and enhance the impact resistance of the substrate 101 on the basis of ensuring the thickness uniformity of the sealant 103.
In an embodiment, as shown in fig. 9a, 9b, and 9c, in a direction perpendicular to the substrate 101, the micro grooves 1011 have a triangular, trapezoidal, or arc cross section along a depth direction thereof.
Specifically, the vertical section of the micro groove 1011 in the depth direction thereof is any one of triangle (as shown in fig. 9 a), trapezoid (fig. 9 b) or arc (fig. 9 c).
