It will be appreciated that all or part of the ports 110, the corresponding circumferential profile may comprise one or more arcuate segments, although the corresponding circumferential profile may be a combination of arcuate segments or a combination of arcuate and linear segments.
Specifically, the arc segments are mainly disposed at corners of the circumferential profile of the fitting port 110, so that tearing of the screen body 100 due to excessive opening of the fitting port 110 can be reduced. Of course, at other locations of the circumferential contour of the adapter opening 110, arcuate segments may also be provided to avoid tearing situations as much as possible.

Specifically, in order to reduce the influence of the formation of the adaptation ports 110 on the light emitting region in the panel body 100, the panel body 100 is divided into the light emitting region 120 and the non-light emitting region 130, the light emitting region 120 and the non-light emitting region 130 are allocated correspondingly according to the arrangement positions of the adaptation ports 110, and the adaptation ports 110 are arranged in the non-light emitting region 130, so that the adverse influence on the light emitting region in the grooving process is reduced. The non-light emitting region 130 is mainly an edge position of the encapsulation layer, and the size of the encapsulation edge is determined according to the size of the screen body 100, for example, the encapsulation edge may be 0.5 mm to 5 mm.

Because the non-light-emitting area 130 is provided with the adapting port 110, in order to prevent water vapor and the like from penetrating inwards along the organic material, the non-light-emitting area 130 is further provided with a plurality of blocking dams 133, the cross section of each blocking dam 133 can be inverted trapezoid, rectangle, triangle and the like, the cross section is not limited to the cross section, and the blocking dams 133 are preferably made of inorganic materials, such as silicon oxide, silicon nitride and the like, so that the invasion of the water vapor can be effectively prevented, the erosion path of the water vapor along the invasion of the organic material is prolonged, and the invasion difficulty is improved.
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 the flexible substrate layer 131, the barrier adhesive layer 136 and the barrier film layer 137 stacked in the thickness direction of the screen body 100, and at least one elastic stretch yarn 200 is embedded in one of the flexible substrate layer 131, the barrier adhesive layer 136 and the barrier film layer 137. It is to be understood that other layer structures of the non-light emitting region 130 are as described in the above embodiments, and will not be described herein.
In the present embodiment, when at least one elastic stretch yarn 200 is embedded in the flexible substrate layer 131, the remaining elastic stretch yarns 200 are not limited, when at least one elastic stretch yarn 200 is embedded in the barrier adhesive layer 136, the remaining elastic stretch yarns 200 are not limited, and when at least one elastic stretch yarn 200 is embedded in the barrier film layer 137, the remaining elastic stretch yarns 200 are not limited. The elastic tension lines 200 are fitted to the flexible substrate layer 131, for example. The fitting arrangement is understood to mean that the elastic tension lines 200 are embedded in the flexible substrate layer 131, so that smoothness of the surface of the screen body 100 can be ensured.
The embedded arrangement is prepared by placing the flexible substrate layer 131 in a plate groove with a preset shape, pouring a material for preparing the flexible substrate layer 131, adjusting the position of the elastic stretching wire 200 by a clamp, and solidifying after a period of time to obtain the flexible substrate layer 131 embedded with the elastic stretching wire 200, wherein 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, and the melting temperature of the elastic stretching wire 200 is higher than that of the flexible substrate layer 131.
It will be appreciated that the flexible substrate layer 131 is placed in a plate groove of a preset shape, after curing, openings are available based on the preset shape, and when other layer structures are prepared, the openings are avoided according to the opening shape, and finally the adaptation openings 110 are obtained together.
Based on the above-mentioned fitting arrangement, as shown in fig. 8, illustratively, the end of at least one elastic stretching wire 200 is provided with a limit tab 300 embedded in one layer of the flexible substrate layer 131, the barrier adhesive layer 136 and the barrier film layer 137, the elastic stretching wire 200 is disposed at an angle to the limit tab 300, and the projection profile of the elastic stretching wire 200 at the end is smaller than the projection profile of the limit tab 300 at the end of the elastic stretching wire 200.

Depending on the location of the elastic stretch yarn 200, it is mated with the flexible substrate layer 131 or the barrier glue layer 136 or the barrier film layer 137, respectively. The elastic tension lines 200 are provided in the flexible substrate layer 131, for example.
The limit tab 300 may be integrally formed with the elastic stretch wire 200 or may be formed separately, with the two being in a secure attachment relationship. The projection profile of the limit lug 300 at the end of the elastic stretching wire 200 is larger than that of the elastic stretching wire 200 at the end of the elastic stretching wire 200, and the limit lug 300 and the flexible substrate layer 131 are arranged in an angle, so that the limit lug 300 has a larger contact area with the flexible substrate layer, and the elastic stretching wire 200 can be prevented from being separated in the stretching process of the elastic stretching wire 200. Preferably, the limit tabs 300 are disposed at a 90 ° angle to the elastic stretch line 200. The limit tab 300 may be a regular or irregular shape such as a cylinder, a prism, etc., without limitation.
Based on the above description of the non-light emitting region 130, in a specific embodiment, the non-light emitting region 130 includes the flexible substrate layer 131, the barrier adhesive layer 136 and the barrier film layer 137 which are stacked in the thickness direction of the screen body 100, and at least one of the flexible substrate layer 131, the barrier adhesive layer 136 and the barrier film layer 137 forms the fitting opening 110 and the elastic stretching wire 200 by one of screen printing, printing and laser cutting. The flexible substrate layer 131 is exemplified.

The flexible substrate layer 131 is at least one of polyester elastic material, acryl elastic material, vinyl elastic material and fluorosilicone elastic material, and is formed by first forming a whole layer of flexible substrate on a base plate, and directly forming the opening and the elastic stretching wire 200 by means of screen printing, laser cutting and the like. The multiple layers together form the fitting opening 110, avoiding the opening, when preparing the other layer structure. Therefore, the opening ratio can be reduced, the area of water and oxygen invasion is reduced, and the whole device can be prevented from being excessively bent.
Of course, in other embodiments, a manner of forming the fitting port 110 by film packaging and then slotting may be adopted, for example, after packaging is completed, the screen body 100 is slotted to form the fitting port 110, the elastic stretching wire 200 is disposed on the light emitting surface or the non-light emitting surface of the screen body 100 corresponding to the position of the fitting port 110, for example, the elastic stretching wire 200 is directly bonded on the non-light emitting surface, for example, a groove is formed on the non-light emitting surface, and the end of the elastic stretching wire 200 is disposed in the groove and then bonded, which is not limited thereto.
