The requirements of the end consumers on the size of the frame and the thickness of the display module are becoming more and more severe, and how to design a module structure with a narrow frame and an ultra-thin thickness is a problem to be solved. The realization of narrow frame scheme mainly relies on the binding region to buckle to make the driving chip buckle to the back of display module assembly and realize. However, in the existing preparation process, when the binding area is bent, bending abnormality and cracks often occur, so that the yield of the display module is low.
Based on the above, the embodiment of the invention provides a display module, a manufacturing method thereof and a display device, which effectively solve the technical problems existing in the prior art, reduce the bending abnormality and crack conditions during the preparation of the display module, and ensure the higher yield of the display module.
In order to achieve the above objective, the technical solutions provided by the embodiments of the present invention are described in detail below, with reference to fig. 1 to 12.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a display module provided by an embodiment of the present invention, and fig. 2 is a schematic structural diagram of a display panel with a folded portion provided by an embodiment of the present invention, where the display module includes:
the display panel 100, the display panel 100 includes a display area AA and a binding area BA located at one side of the display area AA, and the binding area BA includes a bending portion 110 bending toward one side of the display surface 101 facing away from the display panel 100.
And an encapsulation adhesive layer 200 covering the bending portion 110 on one side surface of the display surface 101.
The surface energy of the anti-adhesion layer 300 is smaller than the surface energy of the encapsulation adhesive layer 200, and the anti-adhesion layer 300 is positioned on the side of the encapsulation adhesive layer 200 away from the bending part 110.
An adhesion layer 400 located on a side of the release layer 300 facing away from the display panel 100, covering the display area AA, and extending over at least a portion of the release layer 300.
And a cover plate 500 positioned on a side of the attaching layer 400 facing away from the display panel 100.
In an embodiment of the present invention, the display panel 100 provided by the present invention may be a self-luminous display panel. And, the binding area BA provided by the present invention further includes a binding portion 120 located at a side of the bending portion 110 away from the display area AA. And, the display module further includes a SCF (Super Clean Foam) layer 600 and a driving chip 700 disposed on a side of the display panel 100 facing away from the display surface 101, wherein the binding portion 120 is in binding connection with the driving chip 700.
From the foregoing, it can be seen that, according to the technical solution provided by the embodiment of the present invention, an anti-adhesion layer is prepared on a side of the encapsulation adhesive layer away from the bending portion, where the adhesion layer covers the display area and extends to cover at least a portion of the anti-adhesion layer, even if the adhesion layer adheres between the side of the adhesion layer away from the display area and the encapsulation adhesive layer, the adhesion area between the adhesion layer and the encapsulation adhesive layer is reduced due to the existence of the anti-adhesion layer, so that the pulling force of the adhesion layer on the bending portion can be reduced, the abnormal and crack conditions occurring when the bending portion is bent are improved, the breakage rate of the display module during preparation is reduced, and the yield of the display module is ensured to be higher.
Referring to fig. 1 and fig. 2, the encapsulation adhesive layer 200 provided in the embodiment of the invention covers the bending portion 110, where the encapsulation adhesive layer 200 may be a UV adhesive layer (ultraviolet curing adhesive layer), and the bending performance of the bending portion 110 can be improved by preparing the encapsulation adhesive layer 200 on the surface of the bending portion 110, which is beneficial for bending the bending portion 110 into an arc shape.

Furthermore, by forming the anti-adhesion layer 300 on the surface of the encapsulation adhesive layer 200, the surface energy of the anti-adhesion layer 300 is smaller than that of the encapsulation layer 200, so that the adhesion between the encapsulation adhesive layer 200 and the adhesion layer 400 can be reduced due to the low surface energy of the anti-adhesion layer 300, even if the adhesion layer 400 overflows to cover more areas of the anti-adhesion layer 300, the adhesion area between the encapsulation adhesive layer 200 and the adhesion layer 400 is still reduced due to the low surface energy characteristic of the anti-adhesion layer 300, the purpose of reducing the corresponding pulling force of the adhesion layer 400 to the bending part 110 is achieved, the influence of the adhesion layer 400 on the bending part 110 is reduced, and the high process yield is ensured.
In one embodiment of the present invention, the surface water drop angle of the anti-adhesion layer 300 provided by the present invention is greater than or equal to 100 °; and/or, the surface peel force of the release layer 300 is less than or equal to 10gf/inch.

The thickness of the anti-adhesive layer 300 may be preferably 10 μm, and the thickness of the anti-adhesive layer 300 is optimized to avoid falling off due to being too thin, and also to avoid affecting bending of the bending portion 110 due to being too thick.
In addition, the attaching layer 400 provided in the embodiment of the present invention may be an OCA optical adhesive layer, which is not particularly limited. When the cover plate 500 and the display panel 100 are attached through the attaching layer 400, the material of the attaching layer 400 overflows, so that the anti-adhesive layer 300 is arranged on one side of the surface of the packaging adhesive layer 200, the adhesion area between the attaching layer 400 and the packaging adhesive layer 200 can be reduced, the corresponding pulling force of the attaching layer 400 to the bending part 110 is reduced, the influence of the attaching layer 400 on the bending of the bending part 110 is reduced, and the high yield of the manufacturing process is ensured.

In addition, the side line of the anti-adhesive layer 300 far away from the side of the display area AA is located within the bending center line of the bending portion 110, so that the influence of the attaching layer 400 on the bending portion 110 is limited, the bending portion 400 can bend along the predetermined bending center line, and the distance between the bending center line and the same side line of the cover plate 500 is ensured to be in accordance with expectations; meanwhile, the bending effect of the bending part 400 can be guaranteed to be high, and the situation that the bending part 400 is cracked is avoided.
