Based on the above description of the non-light-emitting region 130, referring to fig. 8, in a specific embodiment, the non-light-emitting region 130 includes, in the thickness direction of the screen body 100, a flexible substrate layer 131, a barrier adhesive layer 136, and a barrier film layer 137, which are stacked, and at least one elastic stretch line 200 is embedded in one of the flexible substrate layer 131, the barrier adhesive layer 136, and the barrier film layer 137. It is understood that other layer structures of the non-light emitting region 130, such as the above embodiments, are not described herein.
In this embodiment, when at least one elastic stretching thread 200 is embedded in the flexible substrate layer 131, the remaining elastic stretching threads 200 are not limited, when at least one elastic stretching thread 200 is embedded in the barrier film layer 136, the remaining elastic stretching threads 200 are not limited, and when at least one elastic stretching thread 200 is embedded in the barrier film layer 137, the remaining elastic stretching threads 200 are not limited. The following description will discuss an example in which the elastic stretch yarn 200 is fitted to the flexible backing layer 131. The interlocking arrangement is understood to mean that the elastic tension threads 200 are embedded in the flexible substrate layer 131, so that the smoothness of the surface of the screen body 100 is ensured.
The preparation method of the embedding arrangement is that when the flexible substrate layer 131 is formed, the melting temperatures of the flexible substrate layer 131 and the elastic stretching wire 200 are different, the melting temperature of the elastic stretching wire 200 is higher than that of the flexible substrate layer 131, the flexible substrate layer 131 is placed in a plate groove with a preset shape, a material for preparing the flexible substrate layer 131 is poured, the position of the elastic stretching wire 200 can be adjusted through a clamp, and the flexible substrate layer 131 embedded with the elastic stretching wire 200 is obtained after solidification after a period of time.
It will be appreciated that the flexible substrate layer 131 is placed in a plate groove of a predetermined shape, and after curing, an opening is obtained on the basis of the predetermined shape, which opening is avoided according to the shape of the opening when preparing the further layer structure, and finally together the adaptation opening 110 is obtained.
Based on the above-mentioned fitting arrangement, as shown in fig. 8, for example, the end of at least one elastic stretch thread 200 is provided with a limit tab 300 embedded in one of the flexible substrate layer 131, the barrier adhesive layer 136, and the barrier film layer 137, the elastic stretch thread 200 and the limit tab 300 are arranged at an angle, and the projection profile of the elastic stretch thread 200 at the end thereof is smaller than the projection profile of the limit tab 300 at the end of the elastic stretch thread 200. It is understood that the position limiting lug 300 may be disposed on all of the elastic stretching threads 200 or a part of the elastic stretching threads 200, and may be one end of the elastic stretching threads 200 or both ends of the elastic stretching threads 200, which is not limited thereto. According to the arrangement position of the elastic stretching threads 200, the flexible backing layer 131 or the barrier rubber layer 136 or the barrier film layer 137 are correspondingly matched. The description will be given taking as an example that the elastic stretch yarn 200 is provided in the flexible substrate layer 131.
The limiter tab 300 may be formed integrally or separately with the elastic tensile strand 200 in a secure connection. The projection profile of the limit tab 300 at the end of the elastic tensile strand 200 is greater than the projection profile of the elastic tensile strand 200 at the end thereof, and the two are disposed at an angle, so that the limit tab 300 has a larger contact area with the flexible substrate layer 131, and can prevent the elastic tensile strand 200 from being detached during the stretching of the elastic tensile strand 200. Preferably, the restraining tab 300 is disposed at a 90 ° angle to the elastic tensile strand 200. The limit tab 300 may be cylindrical, prismatic, etc. in regular or irregular shapes, without limitation.
Based on the description of the non-light-emitting region 130, in a specific embodiment, the non-light-emitting region 130 includes, in the thickness direction of the screen body 100, a flexible substrate layer 131, a barrier adhesive layer 136, and a barrier film layer 137, which are stacked, and at least one of the flexible substrate layer 131, the barrier adhesive layer 136, and the barrier film layer 137 forms the adapting port 110 and the elastic stretch line 200 by one of screen printing, and laser cutting. The flexible substrate layer 131 is taken as an example for explanation. It is understood that other layer structures of the non-light emitting region 130, such as the above embodiments, are not described herein.
The flexible substrate layer 131 is made of at least one of a polyester elastic material, a acryl elastic material, a vinyl elastic material, and a fluorosilicone elastic material, and an entire flexible substrate is first formed on a substrate, and the opening and the elastic tensile line 200 are directly formed by screen printing, laser cutting, and the like. When preparing the other layer structure, the multi-layer structure together forms the fitting opening 110, avoiding the opening. Therefore, the aperture ratio can be reduced, the area of water and oxygen invasion can be reduced, and the whole device can be prevented from being bent excessively.
