In this embodiment 1, when the auxiliary adhesive film 1 is adhered to the display panel 3, the planar adhesive region 11 is adhered to the planar region 31 of the display panel 3, the short-side bending adhesive region 12 is adhered to the short-side bending region 32 of the display panel 3, the long-side bending adhesive region 13 is adhered to the long-side bending region 33 of the display panel 3, and the corner adhesive region 14 is adhered to the corner bending region 34 of the display panel 3; the short side connecting edge 35 and the short side bending and attaching region 12 have a first distance S therebetween, and the long side connecting edge 36 and the long side bending and attaching region 13 have a second distance L therebetween, and the magnitudes of the first distance S and the second distance L vary with the shape of the corner bending region 34 of the display panel 3.

Specifically, in the process of attaching the prism 2, the auxiliary attaching film 1 and the display panel 3, the prism 2 has a projection on the auxiliary attaching film 1 and the display panel 3 in the first direction, a straight line where a long side of the projection is located coincides with the short side connecting edge 35 on the display panel 3, a straight line where a short side of the projection is located coincides with the long side connecting edge 36 on the display panel 3, and lengths of the long side bending attaching region 13 and the short side bending attaching region 12 of the auxiliary attaching film 1 need to be designed such that two sides of the short side bending attaching region 12 are between the first distance S of the short side connecting edge 35 and the short side bending starting point 37 of the display panel 3, and two sides of the long side bending attaching region 13 are between the long side connecting edge 36 and the second distance L of the long side bending starting point 38 of the display panel 3. The short-side bending and bonding region 12 may vary according to the actual shape and size of the display panel 3 in the first distance S, and the long-side bending and bonding region 13 may vary according to the actual shape and size of the display panel 3 in the second distance L. For example, if the curvature of the corner bending region 34 of the display panel 3 is small, the lengths of the long-side bending region 33 and the short-side bending region 32 of the display panel 3 are long, and the sizes of the first and second distances S and L are correspondingly small, or may even be 0. If the curvature of the corner bending region 34 of the display panel 3 is large, the lengths of the long-side bending region 33 and the short-side bending region 32 of the display panel 3 are relatively short, and at this time, the sizes of the first distance S and the second distance L are correspondingly large, the edge of the long-side bending bonding region 13 may be close to the long-side bending point 38, and the edge of the short-side bending bonding region 12 may be close to the short-side bending point 37. The first distance S and the second distance L can be adjusted simultaneously, and one of them can be fixed to change the other, so long as the four corners and four sides of the prism 2, the auxiliary laminating film 1 and the display panel 3 can be ensured to be contacted simultaneously when lamination is performed, and bubbles are avoided.
Referring again to fig. 6, in the auxiliary adhesive film 1 of the present embodiment 1, when the auxiliary adhesive film 1 is adhered to the display panel 3, the planar adhesive region 11 is adhered to the planar region 31 of the display panel 3, the short-side folded adhesive region 12 is adhered to the short-side folded region 32 of the display panel 3, the long-side folded adhesive region 13 is adhered to the long-side folded region 33 of the display panel 3, and the corner adhesive region 14 is adhered to the corner folded region 34 of the display panel 3; the corner fitting region 14 has a first curved profile R connected between the long-side rounded transition bend section R1 and the short-side rounded transition bend section R2, the corner bending region 34 has a second curved profile R0 connected between the long side of the long-side bending region 33 and the short side of the short-side bending region 32, and the first curved profile R is curved in a direction away from the planar region 31 and has the same curvature as the second curved profile R0.
By adopting the auxiliary adhesive film 1 of this embodiment 1, the synchronization rate of the prism 2, the auxiliary adhesive film 1 and the display panel 3 contacting each other in the bonding process and the occurrence of bubbles can be further improved by changing the shape and size of the corner adhesive region 14 of the auxiliary adhesive film 1.
Specifically, in the lamination process of the prism 2, the auxiliary lamination film 1 and the display panel 3, the long-side fillet transition bending section R1 and the short-side fillet transition bending section R2 in the corner lamination area 14 are designed to be longer in arc length and have a larger curvature, so that the shapes of the long-side fillet transition bending section R1 and the short-side fillet transition bending section R2 are more close to the shape of the first curve profile R of the arc bending section, and the long-side fillet transition bending section R1 and the short-side fillet transition bending section R2 are bent towards the same direction and towards the plane area 31 of the display panel 3, and are opposite to the bending direction of the arc bending section. The first curve profile R of the corner fitting region 14 of the auxiliary fitting film 1 and the second curve profile R0 of the corner bending region 34 of the display panel 3 may have the same curvature, or the curvature of the first curve profile R may be slightly larger than that of the second curve profile R0, so as to mainly adapt to the design of a large curvature arc structure of the long side fillet transition bending section R1 and the short side fillet transition bending section R2 on both sides of the arc bending section, and reduce the risk of the prism 2 and the display panel 3 contacting in advance.
