In particular, the surface of the bracket 2 facing the screen assembly 1 is connected with a corresponding surface on the curved portion 12. For example, the fixing connection may be performed by means of adhesion or dispensing.
One end of the elastic element 3 is fixed on the surface of the bracket 2 arranged towards the end face of the bending part 12, and the other end is fixed on the end face of the bending part 12, therefore, when the flat part 11 is bent under the action of external operation, corresponding stress б can be generated in the bending part 12, under the action of the stress б, the elastic element 3 is deformed to provide acting force F opposite to the direction of the stress б, and the acting force F is opposite to the direction of the stress б, so that the stress б can be counteracted to a certain extent, the bending performance of the screen component 1 is improved, and the risk of breaking the bending part 12 is reduced.

While the structure between the neutral layer 13 and the first surface may be stretched or compressed based on the difference in the bending direction of the flat portion 11; similarly, the structure between the neutral layer 13 and the second surface may also be stretched or compressed.
Specifically, in one embodiment, and also as shown in FIG. 2, the resilient member may include a first resilient member 31, the first resilient member 31 being positioned between the second surface and the neutral layer 13 at a location where it contacts the end surface of the flexure 12, whereby when the flat portion 11 is bent in a clockwise direction (i.e., from the first surface to the second surface), the structure between the second surface and the neutral layer 13 is compressed, resulting in stress б shown in FIG. 21Stress б1The first elastic element 31 is stretched by the surface of the bending part 12 to generate a force F1The acting force F1Direction and stress б1In the opposite direction, stress б may be counteracted1Lifting deviceThe bending performance of the flexible screen module 100 is improved.
As shown in fig. 3, when the flat portion 11 is bent in the counterclockwise direction (from the second surface to the first surface), the structure between the neutral layer 13 and the second surface is compressed, thereby generating stress б shown in fig. 32Stress б2The first elastic element 31 is compressed by the surface of the bending part 12 to generate a force F2The acting force F2Direction and stress б2In the opposite direction, stress б may be counteracted2The bending performance of the flexible screen module 100 is improved.
In another embodiment, as shown in FIG. 4, the elastic element may comprise a second elastic element 32, the contact position of the second elastic element 32 with the end face of the curved portion 12 is between the first surface and the neutral layer 13, whereby when the flat portion 11 is bent in the clockwise direction (i.e., from the first surface to the second surface), the structure between the first surface and the neutral layer 13 is stretched, resulting in stress б shown in FIG. 43Stress б3The second elastic element 32 is compressed by the surface of the bending part 12 to generate a force F3The acting force F3Direction and stress б3In the opposite direction, stress б may be counteracted1The bending performance of the flexible screen module 100 is improved.
As shown in fig. 5, when the flat portion 11 is bent in the counterclockwise direction (from the second surface to the first surface), the structure between the neutral layer 13 and the first surface is compressed, thereby generating stress б shown in fig. 54Stress б4The second elastic element 32 is stretched to generate a force F by acting on the surface of the bending part 124The acting force F4Direction and stress б4In the opposite direction, stress б may be counteracted4The bending performance of the flexible screen module 100 is improved.

Specifically, when the flat portion 11 is bent, the first elastic element 31 and the second elastic element 32 are used to counteract the internal stress, which is detailed in the embodiments shown in fig. 2 to 5 and will not be described herein again.
In the above embodiments, it may be that the surface of the encapsulation glass included in the screen assembly 1 is adhered to the frame 21; alternatively, as shown in fig. 6, the neutral layer 13 of the screen unit 1 may be bonded to the frame 21, and therefore, when the flat portion 11 is bent, the neutral layer 13 is not deformed, and thus, the influence of stress on the connection stability between the screen unit 1 and the frame 21 can be avoided.
In this embodiment, in the width direction of the screen assembly 1, a plurality of brackets 2 may be disposed, and an adaptive elastic element may be disposed on each bracket 2 to relieve the stress in each area of the screen assembly 1, so as to further enhance the bending performance of the screen assembly 1. The elastic element may include a spring or a structure capable of deforming such as a soft rubber pad, and the disclosure is not limited thereto.
