Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Features in the embodiments described below may be combined with each other without conflict.

The first embodiment is as follows:

As shown in fig. 1 and 3, the curved screen assembly 1 includes an elastic PAD (2) and a bonding tool for bonding, the flexible display module 11 is bonded to the inner side of a curved glass 12 to form a screen assembly 1, and the screen assembly includes a base portion 22 and a top pressing portion 21, wherein the top surface of the top pressing portion 21 is an arc-shaped upper arc surface 211; two sides of the pressing portion 21 are provided with side wings 212 for pressing the flexible display module 11 to be attached to the arc surface portions of the two sides of the curved glass 12, and the side wings 212 are of a suspended structure. The elastic PAD (2) in this embodiment is made of rubber.

The width between the end faces of the two side wings 212 of the pressing part 21 is larger than that of the base part 22. The lower surface of the shoulder 212 is curved and smoothly transitions with the side of the base 22. The side wing 212 has a space for bending and deforming downwards below. The two side edges of the bottom of the base part 22 are provided with material shortage grooves 221 extending along the length direction. The section of the material shortage groove 221 is a 90-degree circular arc.

The curved screen assembly 1 attaching tool shown in fig. 3 comprises an attaching jig 3 and an elastic PAD (2), wherein the elastic PAD (2) is an elastic device for attaching the curved screen assembly 1. The laminating tool 3 is provided with a mounting groove for fixing the elastic PAD (2).

it should be noted that, the curved screen assembly 1 is to attach the flexible display module 11 to the curved glass 12 through the transparent optical adhesive, and in the process of attachment, the attachment of the two structures needs to ensure that the curvature relationship between the two structures meets the use requirement, that is, the pressing portion 21 is deformed to form a suitable curvature relationship with the screen assembly 1 and to have sufficient and uniform pressure to prevent bubbles from remaining on the curved screen assembly 1.

As shown in fig. 2, the suspended structure is that two side surfaces of the pressing portion 21 protrude from the base 22, and the width gradually decreases from top to bottom, so that the strength of the side wing 212 of the pressing portion 21 decreases, and the flexible display module 11 has a fitting curvature adapted to the fitting surface of the curved glass 12 in the fitting process.

As shown in fig. 1 and 2, the side surface of the base portion 22 is a vertical surface, and the vertical surface is tangent to the lower surface of the side wing 212 of the hold-down portion 21 at the contact position.
