[0002] In recent years, foldable and bendable display devices have gradually become popular. Flexible display panels have attracted more and more attention due to their softness, ability to be bent into a curved surface, and many other advantages. Curved display devices (such as curved screens and waterfall screens) made of flexible display panels with a certain angle are favored by consumers due to their beautiful curves, comfortable feel, high screen-to-body ratio, and other advantages.

DETAILED DESCRIPTION

[0038] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, unless otherwise indicated, like numbers in the attached drawings refer to the same or similar elements. The following detailed description includes specific details for the purpose of providing an understanding of the various exemplary embodiments. However, it will be apparent to those skilled in the art that the exemplary embodiments can be practiced without these specific details. In some instances, well-known structures and components are not described in detail in order to avoid obscuring the understanding of the various exemplary embodiments.

[0039] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0040] The development idea of the present application includes:

[0041] The folding module is composed of folding special glue material and functional layers in turn. In order to make each functional layer in a safe stress range, the folding glue material needs to have a large shear deformation, reduce the mutual influence between adjacent functional layers, and achieve the effect of "multiple neutral layers". The deformation of the glue material inevitably leads to the "film layer displacement" phenomenon, that is, the relative position of the functional layers at the edge of the module changes.

[0042] The design of the folding module needs to consider the impact of "film layer displacement". One of them is the distance design from the POL (Polarizer, polarizer) to the SNL (Stress neutralization layer, stress neutral layer).

[0043] On the one hand, in order to reduce the lower border of the conventional narrow frame mobile phone module, the design scheme of directly contacting without gap between one end of the SNL and one end of the POL coated on the display panel is adopted. If the SNL directly contacts the POL, the glue material between the polarizer and the display panel will shear and deform, the edge of the polarizer will follow the displacement, and then drive the stress neutral layer to move, causing cracks in the bending part of the display panel, thereby causing bright lines, abnormal display and other defects. Therefore, a gap between the polarizer and the display panel needs to be reserved, and the gap value needs to meet: Gap = POL lamination tolerance + SNL glue coating tolerance + folding displacement. Generally, the Gap value is taken to be 0.2mm or more.

[0044] On the other hand, reserving the Gap will reduce the specifications of other parts of the folding screen. The display panel wiring between the POL and the SNL is exposed, and when the whole machine or module is subjected to ESD (Electrostatic Discharge) test, the positive discharge will damage the unprotected wiring, causing bright lines and touch screen abnormalities. The static specification of the non-folding module with the contact between the SNL and the POL can reach ±8KV, while the static of the folding module can only reach ±6KV. This design undoubtedly reduces the anti-static performance of the folding display device.

[0045] The display module and the manufacturing method thereof and the display device provided in the present application aim to solve the above technical problems in the prior art.

[0046] The display module and the manufacturing method thereof and the display device in the embodiments of the present application will be described in detail below with reference to the drawings. In the case of no conflict, the features in the following embodiments can be complementary or combined with each other.

[0047] The present application provides a display module. As shown in Figure 1As shown, the display module includes: a display panel 3, a polarizer 4, a cover plate 5, a stress neutral layer 6, a first conductive layer 1, and a second conductive layer 2. The display panel 3 includes a display section, a bending section, and a bonding section connected in sequence; the display section has a light-emitting side and a backlight side disposed opposite to each other; the bending section is bendable so that the bonding section bends to the backlight side of the display section. The polarizer 4 is disposed on the side of the display section near the light-emitting side; the cover plate 5 is disposed on the side of the polarizer 4 away from the light-emitting side of the display section; the stress neutral layer 6 is disposed on the side of the display panel 3 near the light-emitting side, covering the edge region of the display section near the bending section of the polarizer 4 and the bending section; the first conductive layer 1 covers the edge region of the cover plate 5 near the bending section; the second conductive layer 2 covers a portion of the stress neutral layer 6 on the side away from the display panel 3 and near the first conductive layer 1; the surface of the first conductive layer 1 near the stress neutral layer 6 is in contact with the surface of the second conductive layer 2 near the cover plate 5.

[0048] In this embodiment, a first conductive layer 1 is provided on the edge region of the cover plate 5 near the bend in the display module, and a second conductive layer 2 is provided on the side of the stress neutral layer 6 away from the display panel 3 and near the first conductive layer 1. The surface of the first conductive layer 1 near the stress neutral layer 6 is in contact with the surface of the second conductive layer 2 near the cover plate 5. This allows the current generated by electrostatic discharge to flow along the direction from the second conductive layer 2 to the first conductive layer 1 when the display module is subjected to high voltage on the side near the light-emitting side, and finally flow to the frame of the display panel 3 for safe release. Therefore, the risk of the light-emitting side traces of the display panel 3 being damaged is reduced, and the anti-static capability of the display module is improved.

[0049] In some embodiments, the stress-neutral layer 6 may be made of acrylate.

[0050] It should be noted that the material of the cover plate 5 in this application is a foldable flexible material, which can be CPI (colorless polyimide), PET (polyethylene terephthalate), or UTG (ultra-thin glass).

[0051] In some embodiments, such as Figure 1 As shown, the cover plate 5 and the polarizer 4 are bonded and fixed together by a first adhesive layer 8. Specifically, the material of the first adhesive layer 8 can be OCA (Optically Clear Adhesive).

[0052] The display module further comprises a support layer 9. The material of the support layer 9 can be stainless steel (Steel Use Stainless, SUS), titanium alloy, or carbon fiber reinforced polymer (CFRP). The stainless steel, titanium alloy, and carbon fiber reinforced polymer have certain support properties, and can support the cover plate 5 and the display panel 3 to ensure the screen form of the display module. The stainless steel layer can be SUS301 or SUS316. Those skilled in the art can make reasonable choices according to actual conditions, and the choices are not limited thereto.

[0053] The display module further comprises a metal layer 10. The material of the metal layer 10 can be steel or aluminum alloy. The metal layer 10 is used to support and supplement the strength of the display module. The metal layer 10 is arranged only in the display part, and is not arranged in the bending part. When the bending part is bent, the cover plate 5, the display panel 3, and the support layer 9 will all be bent at positions corresponding to the bending part. In order to ensure that the cover plate 5, the display panel 3, and the support layer 9 can all be bent, the cover plate 5, the display panel 3, and the support layer 9 need to have certain flexibility, which will inevitably result in insufficient rigidity of the cover plate 5, the display panel 3, and the support layer 9, and insufficient support force of the foldable display module. The metal layer 10 can support the cover plate 5, the display panel 3, and the support layer 9 in regions outside the bending part, to ensure the support force of the foldable display module. The steel plate has great strength, and can ensure the support force of the foldable display module.

[0054] The display module further comprises an organic insulating layer 12. The organic insulating layer 12 is arranged between the display panel 3 and the support layer 9 of the display part, and is fixed by the second adhesive layer 11. Specifically, the material of the second adhesive layer 11 is PSA (Pressure Sensitive Adhesive). The organic insulating layer 12 is also arranged on the side of the display panel 3 of the binding part that is close to the cover plate 5. The material of the organic insulating layer 12 is PET or PI (Polyimide).

[0055] The display module further comprises an adhesive pad 13 arranged on the side of the metal layer 10 that is away from the display panel 3. The adhesive pad 13 not only has a gluing effect, but also can buffer the mechanical force in the bending process of the display module, to absorb and dissipate impact energy. In an example, the adhesive pad 13 is foam.

[0056] In some embodiments, the water drop angle of the first conductive layer 1 close to the surface of the stress neutral layer 6 is greater than or equal to 90°. The surface of the first conductive layer 1 can be ensured not to be wetted, so that the surface of the first conductive layer 1 will not have adhesion.

[0057] In one embodiment, the second conductive layer 2 has a water droplet angle of greater than or equal to 90° on the surface close to the cover plate 5. The surface of the second conductive layer 2 can be guaranteed not to be wetted, so that the surface of the second conductive layer 2 will not produce stickiness.

[0058] According to the above embodiment, the surfaces of the first conductive layer 1 and the second conductive layer 2 do not produce stickiness, and the adhesion between the two can be guaranteed, thereby producing a stickiness frictional resistance, which can avoid the problem of adhesion between the stress neutral layer 6 and the cover plate 5 in the conventional scheme, thereby improving the flexibility of the display module when bending, avoiding cracking in the bending area, and improving the service life of the display module.

[0059] In some embodiments, the first conductive layer 1 has a water droplet angle of greater than or equal to 105° on the surface close to the stress neutral layer 6, and the second conductive layer 2 has a water droplet angle of greater than or equal to 100° on the surface close to the cover plate 5. Further increasing the water droplet angles of the first conductive layer 1 and the second conductive layer 2 can better guarantee that the first conductive layer 1 and the second conductive layer 2 will not be adhered.

[0060] In some embodiments, the material of the first conductive layer 1 is a hydrophobic conductive material or an oleophilic conductive material. Specifically, the material of the first conductive layer 1 can be conductive ink. Good conductive performance can be provided to ensure that electrons form an electric current in the conductive ink to achieve electrostatic discharge.

[0061] In some embodiments, as shown in FIG. 1, the cover plate 5 is provided with a layer of printing ink 16 on the side close to the light-emitting side of the display panel 3, and part of the first conductive layer 1 is arranged on the side of the printing ink 16 away from the cover plate 5. Figure 2

[0062] In some embodiments, the first conductive layer 1 is arranged in a semi-enclosed manner on the edge region of the cover plate 5 close to the stress neutral layer 6.

[0063] In some embodiments, the thickness of the first conductive layer 1 is 4-7 μm.

[0064] In some embodiments, as shown in FIG. 1, the first conductive layer 1 is made by the dipping method, and one end of the cover plate 5 provided with the printing ink 16 close to the stress neutral layer 6 is immersed in the conductive ink liquid 15 to form a solid ink after solidification. Figure 3 In some embodiments, the material of the second conductive layer 2 is a single type of conductive material or a composite type of conductive material.

[0065]

[0066] ​​In some embodiments, the second conductive layer 2 is made of a transparent conductive oxide material such as ITO (Indium Tin Oxide), IZO (Indium Zinc Oxide), or IGZO (Indium Gallium Zinc Oxide), or a transparent conductive coating prepared by doping a small amount of fluorine or antimony in these compounds.

[0067] In some embodiments, the second conductive layer 2 is made of a conductive material such as a metal element and its oxide.

[0068] In some embodiments, the second conductive layer 2 is made of UV-curable glue (UV glue) which is cured by irradiation with a UV light source 14. For non-conductive UV glue, a conductive material can be added to make the UV glue conductive.

[0069] In some embodiments, as shown in FIG. 2, the second conductive layer 2 includes an adhesive layer 21, an insulating layer 22, and a sub-conductive layer 23 which are stacked in sequence, and the sub-conductive layer 23 is closer to the cover plate 5 than the adhesive layer 21. The insulating layer 22 serves to support the sub-conductive layer 23. Figure 4

[0070] In some embodiments, the adhesive layer 21 is made of pressure sensitive adhesive (PSA) or optical clear adhesive (OCA).

[0071] In some embodiments, the insulating layer 22 is made of PET (Polyethylene terephthalate).

[0072] In one example, the distance between the stress neutral layer 6 and the cover plate 5 in a direction perpendicular to the display panel 3 is 30 μm, the thickness of the printed ink 16 is 5 μm, the thickness of the first conductive layer 1 is 5 μm, and the second conductive layer 2 is made of a PET substrate, a sub-conductive layer 23, and an adhesive layer 21, wherein the thickness of the PET substrate is 15 μm, the thickness of the sub-conductive layer 23 is 5 μm, and the thickness of the adhesive layer 21 is 10 μm. The thickness of the second conductive layer 2 is 30 μm, plus the thickness of the printed ink 16 and the first conductive layer 1, which is 40 μm in total, greater than the distance between the stress neutral layer 6 and the cover plate 5 by 10 μm, to ensure that the first conductive layer 1 and the second conductive layer 2 are in effective contact, thereby realizing current conduction.

[0073] In some embodiments, the distance between the stress neutral layer 6 and the polarizer 4 is greater than zero, and the distance between the second conductive layer 2 and the polarizer 4 is greater than zero.

[0074] ​In one example, the distance between the stress neutral layer 6 and the polarizer 4 is greater than 0.2 mm. It can be ensured that the deformation of the bending part does not occur when folding, and display abnormalities caused by film layer displacement are avoided.

[0075] In some embodiments, the display module further includes a middle frame 7 surrounding a side of the display panel 3 close to the light-out side, and a surface of the middle frame 7 at least partially contacts a surface of the first conductive layer 1.

[0076] In the present embodiment, the surface of the middle frame 7 of the display panel 3 at least partially contacts the surface of the first conductive layer 1, so that static electricity can be transmitted from the bending part (i.e., the first conductive layer 1 and the second conductive layer 2) of the display panel 3 to the middle frame 7 to be released.

[0077] In some embodiments, as shown in the drawings, the middle frame 7 includes a first sub-middle frame 71 and a second sub-middle frame 72. The first sub-middle frame 71 is arranged in an "L" shape around the outer periphery of the display panel 3. One end of the second sub-middle frame 72 is overlapped with an edge of the first sub-middle frame 71, and the side of the second sub-middle frame 72 close to the light-out side of the display panel 3 contacts the side of the cover plate 5 away from the light-out side of the display panel 3 to achieve static electricity transmission, so as to safely release static electricity and improve the anti-static capability of the display module. Figure 9 Based on the same inventive concept, as shown in the drawings, the present application provides a manufacturing method of a display module, which includes:

[0078] Figures 5 to 8 S1: providing a display panel 3, the display panel 3 including a display part, a bending part and a binding part connected in sequence; the display part having a light-out side and a backlight side arranged oppositely; the bending part being bendable to bend the binding part to the backlight side of the display part;

[0084] S6: fixing the cover plate 5 to a side of the polarizer 4 away from the light-out side of the display part;

[0085] ​The surface of the first conductive layer 1 close to the stress neutral layer 6 is in contact with the surface of the second conductive layer 2 close to the cover plate 5.

[0086] In one embodiment, the second conductive layer 2 is formed on the part of the stress neutral layer 6 away from the display panel 3 and close to the first conductive layer 1, comprising: forming the second conductive layer 2 on the part of the stress neutral layer 6 away from the display panel 3 and close to the first conductive layer 1 by pasting, the second conductive layer 2 comprising a bonding layer 21, an insulating layer 22 and a sub-conductive layer 23 arranged in layers, the sub-conductive layer 23 being closer to the cover plate 5 than the bonding layer 21.
