DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort also belong to the protection scope of the present application.

[0022] According to the first aspect of the present application, as Figure 1 and Figure 2 ​​As shown, a display module 1 is provided, including a display panel 10 and a functional layer 20. The functional layer 20 is disposed on the light-emitting surface side of the display panel 10. The functional layer 20 includes a reinforcing layer 21 and a curing layer 22. The curing layer 22 wraps around the reinforcing layer 21. The hardness of the reinforcing layer 21 is greater than that of the curing layer 22, and the curing layer 22 is adhesive.

[0023] Display module 1 can be a flexible display product, which can be folded and is easier to carry.

[0024] In some embodiments, the display panel 10 may be an OLED panel, a Mini-LED panel, a Micro-LED panel, etc.

[0025] The display panel 10 includes a display area and a non-display area surrounding the display area. The display area can have multiple sub-pixels, including red, green, and blue sub-pixels, to achieve color display. The display area is equipped with a pixel driving circuit for driving the sub-pixels. The non-display area can have a gate driving circuit, which provides driving signals to the sub-pixels.

[0026] The display panel 10 may include an array substrate, a light-emitting layer disposed on the array substrate, and an encapsulation layer disposed on the light-emitting layer. The array substrate includes a substrate and a driving circuit layer disposed on the substrate.

[0027] In some embodiments, the substrate may be a flexible material, such as one of polyimide (PI), polycarbonate (PC), polynorbornene (PNB), and polyethylene terephthalate (PET).

[0028] The light-emitting layer may include a stacked anode, a light-emitting material layer, and a cathode. Holes are injected into the anode, and electrons are injected into the cathode. The holes and electrons recombine in the light-emitting material layer to emit light. The driving circuit layer is electrically connected to the anode and cathode respectively, and is used to provide driving signals to the anode and cathode.

[0029] In some embodiments, the anode material can be a metal or metal oxide material, such as one or more of indium tin oxide, indium zinc oxide, silver, etc.

[0030] In some embodiments, the cathode material can be an alloy of one or more of the following: silver, aluminum, and magnesium.

[0031] In some embodiments, the encapsulation layer is disposed on the side of the cathode away from the array substrate, and the encapsulation layer may be formed by alternatingly stacked one or more organic layers and one or more inorganic layers. For example, the organic layer may be a single layer or multiple layers formed of any one of polyethylene terephthalate, polyimide, polycarbonate, epoxy resin, polyethylene, and polyacrylate. The inorganic layer may be a single layer or multiple layers of metal oxide or metal nitride, such as silicon nitride, alumina, silicon oxide, etc.

[0032] like Figure 1 and Figure 2 As shown, the display panel 10 has a light-emitting surface used for displaying images. The functional layer 20 is disposed on the side of the light-emitting surface of the display panel 10.

[0033] In some embodiments, the reinforcing layer 21 can be ultra-thin glass (UTG), ultra-foldable glass (UFG), etc. The reinforcing layer 21 has high hardness, which can improve the surface hardness of the display module 1 and effectively enhance the mechanical performance of the screen. For example, a display module 1 with a reinforcing layer 21 can improve its performance in mechanical reliability tests, such as pen drop tests and ball drop tests.

[0034] Before curing, the cured layer 22 is an adhesive layer 51, such as optically clear resin (OCR). After curing, the adhesive layer 51 forms the cured layer 22, which is adhesive and can bond with other film layers. The adhesive layer 51 can be formed on the light-emitting surface of the display panel 10 by processes such as inkjet printing, but is not limited to these methods.

[0035] The hardness of the reinforcing layer 21 is greater than that of the curing layer 22. The reinforcing layer 21 is used to increase the screen hardness of the display module 1. The curing layer 22 can be used for bonding and can also wrap the reinforcing layer 21, thus eliminating the need for the step of applying a protective coating to the surface of the reinforcing layer 21. In other words, the curing layer 22 can also protect the reinforcing layer 21.

[0036] The reinforcing layer 21 itself is not adhesive. In related technologies, adhesive layers are required on both sides of the reinforcing layer 21 to assemble it with the display panel 10. Simultaneously, a protective coating is also required on the surface of the reinforcing layer 21 to protect it. The protective coating and adhesive layer need to be fabricated in different equipment, thus increasing the complexity of the process.

[0037] In the embodiments of this application, an adhesive layer 51 is formed on the light-emitting surface of the display panel 10, and a reinforcing layer 21 is placed in the adhesive layer 51, thus encapsulating the reinforcing layer 21. After the adhesive layer 51 cures, a cured layer 22 is formed. The cured layer 22 is adhesive and can be directly bonded to other film layers. At the same time, since the cured layer 22 encapsulates the reinforcing layer 21, a protective coating can be omitted, thereby simplifying the manufacturing process of the display module 1 with the reinforcing layer 21.

[0038] In some embodiments, the cured layer 22 may be in contact with the display panel 10. Contact refers to the direct contact between the surfaces of the two materials. Because the cured layer 22 is adhesive, it can be directly bonded to the display panel 10.

[0039] Optionally, such as Figure 1 and Figure 2 As shown, the area of ​​the surface of the functional layer 20 near the display panel 10 is less than or equal to the area of ​​the surface of the display panel 10 near the functional layer 20.

[0040] Since the cured layer 22 is formed directly on the light-emitting surface of the display panel 10, in order to prevent the uncured adhesive layer 51 from overflowing onto the side wall of the display panel 10, the orthographic projection pattern of the cured layer 22 on the display panel 10 is recessed relative to the light-emitting surface of the display panel 10, that is, the orthographic projection pattern of the cured layer 22 is spaced at a certain distance from the outer contour of the light-emitting surface of the display panel 10.

[0041] In some embodiments, the distance between the orthographic projection pattern of the cured layer 22 on the display panel 10 and the outer contour of the light-emitting surface of the display panel 10 can be from 100 micrometers to 300 micrometers. Specifically, the distance between the cured layer 22 and the outer contour of the light-emitting surface of the display panel 10 can be 100 micrometers, 120 micrometers, 140 micrometers, 160 micrometers, 180 micrometers, 200 micrometers, 220 micrometers, 240 micrometers, 260 micrometers, 280 micrometers, 300 micrometers, etc.

[0042] In some embodiments, such as Figure 1 and Figure 2 As shown, the area of ​​the surface of the functional layer 20 closest to the display panel 10 is smaller than the area of ​​the surface of the display panel 10 closest to the functional layer 20. This means that the orthographic projection of the functional layer 20 onto the light-emitting surface of the display panel 10 lies within the light-emitting surface, and the area of ​​the orthographic projection of the functional layer 20 is smaller than the area of ​​the light-emitting surface. This design prevents the cured layer 22 from overflowing onto the sidewalls of the display panel 10 before curing, thus avoiding any impact on the flatness of the sidewalls of the display panel 10.

[0043] In some embodiments, the area of ​​the surface of the functional layer 20 closest to the display panel 10 is equal to the area of ​​the surface of the display panel 10 closest to the functional layer 20. This means that the orthographic projection of the functional layer 20 onto the light-emitting surface of the display panel 10 lies within the light-emitting surface, and the area of ​​the orthographic projection of the functional layer 20 is equal to the area of ​​the light-emitting surface. This configuration prevents the cured layer 22 from overflowing onto the sidewalls of the display panel 10 before curing, thus avoiding any impact on the flatness of the sidewalls. Simultaneously, the functional layer 20 can cover the edges of the display panel 10, protecting those edges.

[0044] Optionally, such as Figure 3 As shown, the thickness d1 of the functional layer 20 is greater than or equal to 1.6 times the thickness d2 of the reinforcing layer 21.

[0045] The thickness d1 of the functional layer 20 refers to the distance between the surface of the functional layer 20 closest to the display panel 10 and the surface of the functional layer 20 furthest from the display panel 10. The thickness d2 of the reinforcing layer 21 refers to the distance between the surface of the reinforcing layer 21 closest to the display panel 10 and the surface of the reinforcing layer 21 furthest from the display panel 10. d2 is the dimension of the sidewall of the reinforcing layer 21 in the direction of the thickness d2 of the reinforcing layer 21.

[0046] In some embodiments, the thickness d1 of the functional layer 20 is 1.6 times the thickness d2 of the reinforcing layer 21.

[0047] In some embodiments, the thickness d1 of the functional layer 20 is greater than 1.6 times the thickness d2 of the reinforcing layer 21. For example, the thickness d1 of the functional layer 20 is 1.7 times, 1.8 times, 1.9 times, 2.0 times, etc., the thickness d2 of the reinforcing layer 21.

[0048] Optionally, such as Figure 3 As shown, the angle A1 between the outer wall of the functional layer 20 and the bottom wall of the functional layer 20 is less than or equal to 90 degrees.

[0049] The outer wall of functional layer 20 refers to the side wall that connects the top wall and the bottom wall of functional layer 20. The top wall of functional layer 20 is the surface of functional layer 20 away from display panel 10, and the bottom wall of functional layer 20 is the surface of functional layer 20 close to display panel 10.

[0050] In some embodiments, the angle A1 between the outer wall of the functional layer 20 and the bottom wall of the functional layer 20 is 75 degrees, 76 degrees, 77 degrees, 78 degrees, 79 degrees, 80 degrees, 81 degrees, 82 degrees, 83 degrees, 84 degrees, 85 degrees, 86 degrees, 87 degrees, 88 degrees, 89 degrees, 90 degrees, etc.

[0051] Since the cured layer 22 is formed by curing liquid material, when it is not cured, the liquid material flows under the action of gravity, resulting in the surface area of ​​the cured layer 22 on the side closer to the display panel 10 being greater than the surface area of ​​the cured layer 22 on the side farther away from the display panel 10. Since the outer wall of the functional layer 20 is the outer wall of the cured layer 22, the outer wall of the functional layer 20 forms an inclined surface, and the inclined surface forms an acute angle or a right angle with the light-emitting surface of the display panel 10.

[0052] Optionally, such as Figure 3 As shown, the curing layer 22 includes a retaining wall portion 223 disposed on the side of the reinforcing layer 21, a first curing portion 221 disposed between the reinforcing layer 21 and the display panel 10, and a second curing portion 222 disposed on the side of the reinforcing layer 21 away from the display panel 10; wherein, the first curing portion 221 and the retaining wall portion 223 are continuously disposed at the end near the display panel 10, and the second curing portion 222 and the retaining wall portion 223 are continuously disposed at the end away from the display panel 10.

[0053] The first curing section 221, the retaining wall section 223, and the second curing section 222 are made of the same material, so they are manufactured using the same equipment, which further simplifies the manufacturing process of the display module 1.

[0054] In some embodiments, a liquid adhesive wall can be formed first and pre-cured. The adhesive wall encloses and forms a receiving space. An adhesive layer 51 is printed within the receiving space, and a reinforcing layer 21 is placed in the adhesive layer 51. The reinforcing layer 21 sinks under gravity, and the adhesive layer 51 overflows the reinforcing layer 21, covering its top wall. The adhesive layer 51 in the receiving space is then cured. After curing, the adhesive layer 51 in the receiving space and the adhesive wall form a unified whole.

[0055] It should be understood that the adhesive layer 51 located below the reinforcing layer 21 forms a partial structure of the first cured part 221 after curing, the adhesive layer 51 located above the reinforcing layer 21 forms a partial structure of the second cured part 222 after curing, and the adhesive wall located on the side of the reinforcing layer 21 and the adhesive layer 51 located on the side of the reinforcing layer 21 form a retaining wall part 223 after curing.

[0056] In some embodiments, the first curing portion 221 and the second curing portion 222 are made of the same material. The material of the outer wall of the retaining wall portion 223 is different from the materials of the first curing portion 221 and the second curing portion 222. The hardness of the material of the outer wall of the retaining wall portion 223 can be greater than the hardness of the material of the first curing portion 221, thereby increasing the mechanical strength of the side of the functional layer 20. The material of the outer wall of the retaining wall portion 223 is the same as the material of the adhesive wall.

[0057] In other embodiments, the materials of the retaining wall portion 223, the first curing portion 221, and the second curing portion 222 are all the same, thereby further simplifying the manufacturing process of the display module 1.

[0058] Optionally, such as Figure 3 As shown, the barrier portion 223 is disposed around the first curing portion 221, and the second curing portion 222 covers the side surface of the barrier portion 223 away from the display panel 10.

[0059] Since the outer wall of the retaining wall portion 223 is formed by pre-curing the adhesive wall, the retaining wall portion 223 is located around the first cured portion 221. This means that the inner wall of the retaining wall portion 223 is in contact with the first cured portion 221. The inner wall of the retaining wall portion 223 refers to the side wall opposite to the outer wall of the retaining wall portion 223. The distance between the inner wall and the outer wall of the retaining wall portion 223 is the wall thickness of the retaining wall portion 223.

[0060] Since the second cured portion 222 is formed by the curing of the adhesive layer 51, when the second cured portion 222 is not cured, the adhesive layer 51 can overflow onto the upper surface of the retaining wall portion 223, thereby covering the upper surface of the retaining wall portion 223. Through this arrangement, the retaining wall portion 223 and the second cured portion 222 can form a single unit. Because the retaining wall portion 223 and the second cured portion 222 are made of the same material, the bond between materials of the same type is tighter, and film separation is less likely to occur, thus improving the mechanical strength of the functional layer 20.

[0061] Optionally, such as Figure 3 As shown, the second curing portion 222 covers at least a portion of the outer wall of the retaining wall portion 223. Before curing, the adhesive layer 51 within the receiving space can overflow the receiving space, covering not only the upper surface of the retaining wall portion 223 but also a portion of its outer wall. This arrangement increases the contact area between the retaining wall portion 223 and the second curing portion 222, resulting in a tighter connection between them and further enhancing the mechanical strength of the functional layer 20.

[0062] Optionally, such as Figure 1 and Figure 2 As shown, the display module 1 has a folded area BA and non-folded areas NA disposed on both sides of the folded area BA; the reinforcing layer 21 has a groove 21a on the side near the display panel 10, and the groove 21a is disposed corresponding to the folded area BA.

[0063] Display module 1 is a foldable product, and the folding area BA is used for folding. The folding mode of display module 1 can be inward folding, outward folding, etc., but is not limited to these. The non-folding area NA is not used for folding, and in the folded state, the non-folding area NA remains flat.

[0064] In some embodiments, the reinforcing layer 21 has a groove 21a on the side near the display panel 10. With the above-mentioned arrangement, the thickness d2 of the reinforcing layer 21 in the folding area BA can be reduced, thereby improving the folding performance of the reinforcing layer 21.

[0065] like Figure 1 and Figure 2 As shown, the display module 1 also includes an anti-reflection layer 30, which is used to reduce the reflection of ambient light by the display module 1. The anti-reflection layer 30 can be a polarizer or the like. The anti-reflection layer 30 can be disposed between the display panel 10 and the functional layer 20, but is not limited to this.

[0066] In some embodiments, such as Figure 2 As shown, the cured layer 22 can be in contact with the anti-reflective layer 30, that is, the cured layer 22 and the anti-reflective layer 30 are directly bonded.

[0067] Optionally, such as Figure 1 and Figure 2 As shown, the display module 1 also includes a protective layer 40, which is disposed on the side of the functional layer 20 away from the display panel 10, and the protective layer 40 is in contact with the functional layer 20.

[0068] In some embodiments, the display module 1 further includes a protective layer 40, which may be a transparent resin, such as polyimide (PI), polyethylene terephthalate (PET), etc.

[0069] The protective layer 40 is in contact with the functional layer 20. For example, the protective layer 40 can be directly bonded to the curing layer 22.

[0070] According to the second aspect of this application, such as Figures 4A to 4E As shown, a method for manufacturing a display module 1 is provided, including: like Figure 4A As shown, a display panel 10 is provided, the display panel 10 having a light-emitting surface; like Figure 4B As shown, an adhesive layer 51 is formed on the light-emitting surface; like Figure 4C and Figure 4D As shown, a reinforcing layer 21 is placed on the adhesive layer 51, the adhesive layer 51 wraps the reinforcing layer 21, and the adhesive layer 51 is cured to form a cured layer 22. The hardness of the reinforcing layer 21 is greater than the hardness of the cured layer 22.

[0071] In some embodiments, the display panel 10 can be a flexible panel, such as an OLED panel, a Mini-LED panel, a Micro-LED panel, etc.

[0072] In some embodiments, the adhesive layer 51 may be an adhesive with adhesive properties such as OCR, but is not limited thereto. The process for forming the adhesive layer 51 includes, but is not limited to, inkjet printing.

[0073] In some embodiments, such as Figure 4C and Figure 4D As shown, the reinforcing layer 21 is placed in the adhesive layer 51, and the reinforcing layer 21 sinks under gravity, with the adhesive layer 51 covering the upper surface of the reinforcing layer 21. The adhesive layer 51 is then cured to form a cured layer 22. The cured layer 22 is adhesive and can be directly bonded to other film layers.

[0074] In some embodiments, the step of placing the reinforcing layer 21 in the adhesive layer 51 can be performed in a vacuum environment to avoid the formation of air bubbles in the adhesive layer 51.

[0075] like Figure 4E As shown, after the step of curing the adhesive layer 51 to form the cured layer 22, a protective layer 40 is provided. The protective layer 40 is disposed on the side of the cured layer 22 away from the display panel 10, and the protective layer 40 is disposed in contact with the cured layer 22.

[0076] In some embodiments, the protective layer 40 is used to protect the display panel 10, etc., and the material of the protective layer 40 can be one of polyimide (PI), polycarbonate (PC), polynorbornene (PNB), and polyethylene terephthalate (PET). The protective layer 40 can be bonded to the surface of the cured layer 22 away from the display panel 10.

[0077] Optionally, the step of forming the adhesive layer 51 on the gloss-emitting surface includes: A glue wall is formed end to end on the light-emitting surface, and the glue wall is cured. The glue wall encloses and forms an enclosing space. Fill the containment space with adhesive layer 51.

[0078] In some embodiments, the material of the glue wall can be OCR, etc.

[0079] When the glue walls are joined end to end, they form a closed pattern, creating a space within the closed pattern. Pre-curing the glue walls allows them to set and become usable for holding glue, etc.

[0080] In some embodiments, the material of the adhesive wall is the same as that of the adhesive layer 51. Since the bonding between the same materials is tighter, the strength of the functional layer 20 can be improved, and the risk of film separation between the cured structure of the adhesive wall and the cured structure of the adhesive layer 51 can be reduced.

[0081] In other embodiments, the material of the adhesive wall may be different from that of the adhesive layer 51. The adhesive wall may be a material with a higher hardness than the adhesive layer 51, thereby improving the protection of the sidewalls of the reinforcing layer 21.

[0082] In this embodiment, the display terminal can be any product or component with display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator.
