The flexible display module includes, but is not limited to, an OLED (Organic Light Emitting Diode) flexible display module, a QLED (Quantum Dot Light Emitting Diode) flexible display module, and the like.
As shown in fig. 1, the flexible display module 100 provided by the embodiment of the present disclosure includes an edge bending region 110 bending toward a non-display side, and the flexible display module 100 includes:
a support plate 70 extending to the edge bending region 110;
a display panel 40 stacked on one side of the support plate 70 facing the display side and extending to the edge bending region 110;
a flexible cover plate 10, which is stacked on one side of the display panel 40 far away from the support plate 70 and extends to the edge bending area 110;
a first connection layer 60 positioned between the support plate 70 and the display panel 40 and connecting the support plate 70 and the display panel 40;
the transparent adhesive layer 20 is positioned between the flexible cover plate 10 and the display panel 40 and connects the flexible cover plate 10 and the display panel 40; and
and at least one connection structure 80 connecting a portion of the flexible cover 10 located at the edge bending region 110 with a portion of the support plate 70 located at the edge bending region 110.
In the embodiment of the present disclosure, the supporting plate 70 may be a hard metal supporting plate, and the metal supporting plate has an arc-shaped edge, that is, the initial state of the supporting plate 70 is a bending state having the arc-shaped edge. The display panel 40 on one side of the metal supporting plate is a flexible display panel, the display panel 40 and the flexible cover plate 10 are both made of flexible materials, and in addition, the initial states of the display panel 40, the flexible cover plate 10 and other components between the flexible cover plate 10 and the supporting plate 70 can be flat states. In the embodiment of the present disclosure, the display panel 40, the flexible cover plate 10, and the edges of other components between the flexible cover plate 10 and the support plate 70 in the flat state may be attached to the arc-shaped edge of the metal support plate by rolling and pressing, then the support plate 70 and the display panel 40 are connected by the first connection layer 60, and the display panel 40 and the flexible cover plate 10 are connected by the transparent adhesive layer 20, so as to obtain the flexible display module 100 having the edge bending area 110.
The display panel 40 is a flexible display panel, so that the display panel 40 can be bent or the display panel 40 can be bent at a specific angle according to actual requirements. In addition, the display panel 40 may also be a display panel with a touch function. The first connection layer 60 may be a PSA (Pressure Sensitive Adhesive) layer, and when the support plate 70 and the display panel 40 are connected by the PSA layer, the support plate 70 and the display panel 40 may be connected by pressing the PSA layer with a tool such as a roller. The first connecting layer 60 may also be a silicone layer, a rubber layer, or the like, which is not specifically limited in the embodiment of the present disclosure.
The Clear Adhesive layer 20 may be an OCA (Optically Clear Adhesive) Adhesive layer. The transparent adhesive layer 20 and the flexible cover plate 10 both have high light transmittance and low light absorption, so that light generated by the display panel 40 can well penetrate through the transparent adhesive layer 20 and the flexible cover plate 10.
In some embodiments, the display panel 40 includes:
a flexible primer layer 50 disposed on a side of the display panel 40 adjacent to the first connection layer 60, the flexible primer layer 50 extending to the edge bending region 110;
the polarizer layer 20 is disposed on one side of the display panel 40 close to the transparent adhesive layer 20, and the polarizer layer 20 extends to the edge bending region 110.
In the embodiment of the present disclosure, the flexible bottom film layer 50 is made of a flexible material, and is used for separating the central portion of the display panel 40 from the first connection layer 60, so as to protect the display panel 40. The polarizer layer 20 is not only used to separate the transparent adhesive layer 20 from the central portion of the display panel 40 to protect the display panel 40, but also used to control the polarization direction of light, and is used to convert and analyze the light beam generated by the display panel 40 to generate a contrast of brightness, thereby generating a display image.
In a comparative example, as shown in fig. 2, the flexible display module 100 'includes a support plate 70', a first connection layer 60', a flexible primer layer 50', a display panel 40', a polarizer 30', a transparent adhesive layer 20 'and a flexible cover plate 10' stacked in sequence from top to bottom. As shown in fig. 2, the edge of the flexible display module 100 'is bent toward the non-display side to form an edge bending region 110'. The flexible cover plate 10 'is connected with the display panel 40' only through the transparent adhesive layer 20', and the display panel 40' is connected with the support plate 70 'only through the first connection layer 60'. The inventors have found that, when the flexible display module 100 'shown in fig. 2 is tested for reliability, the edges of the display panel 40' and the flexible cover 10 'under the support plate 70' are bent and attached to the support plate 70', and the display panel 40' and the flexible cover 10 'under the support plate 70' are made of flexible materials, so that they have a certain resilience. The display panel 40 'and the flexible cover plate 10' can drive the first connecting layer 60 'and the transparent adhesive layer 20' to deform under the action of the rebounding force, so that the bending edge of the flexible display module is subjected to adhesive opening, and the appearance of the flexible display module is poor. For example, as shown in fig. 3a, the adhesive is released at the first connection layer 60 'of the flexible display module 100'; or as shown in fig. 3b, the glue is removed at the transparent glue layer 20 'of the flexible display module 100'.
In the flexible display module 100 provided by the embodiment of the present disclosure, at least one connection structure 80 is disposed at the edge bending region 110 of the flexible display module 100, and the at least one connection structure 80 connects the flexible cover plates 10 at two sides of the flexible display module 100 with the support plate 70. A display panel 40, a first connecting layer 60 and a transparent adhesive layer 20 are disposed between the flexible cover plate 10 and the support plate 70. The connection structure 80 connects the flexible cover plate 10 and the support plate 70, so that the influence of the elastic force of the display panel 40 and the flexible cover plate 10 on the first connection layer 60 and the transparent adhesive layer 20 is reduced, the first connection layer 60 and the support plate 70 and the transparent adhesive layer 20 and the display panel 40 are not easy to separate, and the phenomenon of adhesive failure at the edge bending part of the flexible display module 100 is improved.
In some embodiments, the portion of the flexible cover sheet 10 located at the edge bending region 110 is folded back on the side of the support sheet 70 facing the non-display side, as shown in fig. 4.
The connection structure 80 includes: an inflected section 101 of the flexible cover 10 and a second connecting layer 90, the second connecting layer 90 being located between the inflected section 101 and the support plate 70 and connecting the inflected section 101 to the support plate 70.
In the embodiment of the present disclosure, one side of the flexible cover 10 located in the edge Bending region 100 is extended, then the extended side is bent, so that the extended side of the flexible cover 10 is folded back toward the direction close to the support plate 70 onto the surface of the support plate 70 away from the display panel 40, and then the folded-back portion 101 of the flexible cover 10 is connected to the surface of the support plate 70 away from the display panel 40 through the second connection layer 90. Wherein, the second connecting layer 90 can be a foam adhesive layer, both sides of which have viscosity, one side of which is adhered to the reverse-folded part 101, and the other side of which is adhered to the surface of the supporting plate 70. The second connection layer may also be a PSA glue layer, a silicone glue layer, and the like, which is not particularly limited in this disclosure.
In the embodiment of the present disclosure, one side of the flexible cover 10 located in the edge bending region 110 is extended and folded back, so that the edge portion of the edge bending region 110 of other components located between the flexible cover 10 and the support plate 70 in the flexible display module 100 can be wrapped by the extended side of the flexible cover 10, thereby preventing the separation at the edge bending region 110, between the flexible cover 10 and the display panel 40, and between the display panel 40 and the support plate 70, and improving the glue failure at the edge bending region of the flexible display module 100.
In some embodiments, the support plate 70 includes a plane portion 701 and a curved portion 702 located at the edge curved region 110, and the inflected portion 101 extends to a side of the plane portion 702 facing the non-display side.
In the embodiment of the present disclosure, as shown in fig. 4, the supporting plate 70 includes a planar portion 701 having a planar shape, and a curved portion 702 having an arc shape, and the curved portion 702 is smoothly butted against the planar portion 701. The inflected section 101 extends from one side of the support panel 70 at the edge bent region 110 to the other side of the support panel 70 after being inflected above the upper surface of the support panel 70 in fig. 4.
In one example, the inflected section 101 can be extended to the curved portion 702 of the support plate 70, with the inflected section 101 being connected to the curved portion 702. In another example, the length of the inflected section 101 may be increased such that the inflected section 101 extends to the flat section 701 through the curved section 702 of the supporting plate 70 to be connected to the curved section 702 and the flat section 701 of the supporting plate 70, thereby increasing the contact area between the inflected section 101 and the supporting plate 70. In yet another example, the inflected section 101 can be made to completely cover the surface of the support plate 70 away from the display panel 40.
In some embodiments, the end of the edge bending region 110 of the flexible display module 100 has a groove 120, and the connection structure 80 is a glue 801 filling the groove 120 and connecting the flexible cover plate 10 and the support plate 70.
In the embodiment of the present disclosure, as shown in fig. 1, the side of the support plate 70 and the side of the flexible cover plate 10 located in the edge bending region 110, which are located at two sides of the flexible display module 100, are extended, so that the height of the side end surface of the other component located at one side of the edge bending region 110 between the support plate 70 and the flexible cover plate 10 is lower than the height of the side end surface of the support plate 70 and the side end surface of the flexible cover plate 10 located in the edge bending region 110. Based on this, a groove 120 is formed at the end side of the edge bending region 110, two side walls of the groove 120 are respectively the surface of the flexible cover plate 10 close to the support plate 70 and the surface of the support plate 70 close to the flexible cover plate 10, and the bottom surface of the groove 120 is the end side surface of the other components between the support plate 70 and the flexible cover plate 10 located in the edge bending region 110.
The glue member 801 is connected to the flexible cover plate 10 and the support plate 70, so that the influence of the elasticity of the display panel 40 and the flexible cover plate 10 on the first connection layer 60 and the transparent glue layer 20 is reduced, the first connection layer 60 and the support plate 70 and the transparent glue layer 20 and the display panel 40 are not easily separated, and the phenomenon of glue failure at the edge bending part of the flexible display module 100 is improved. The material of the adhesive member 801 may be UV (Ultraviolet) adhesive. The UV glue is liquid in a normal state, and can better fill the groove 120, and after filling the groove 120 with the UV glue, the UV glue is irradiated by ultraviolet light and the like, so that the UV glue is cured, and the flexible cover plate 10 and the support plate 70 are connected.
