Description

Technical Field

[0001] This disclosure relates to the field of display technology, and in particular to a display device and a method for manufacturing the same. Background Technology

[0002] Organic light-emitting diode (OLED) display devices have advantages such as self-illumination, high luminous efficiency, energy saving, good flexibility, and wide adaptability to environmental temperature range, and are therefore widely used in various applications.

[0003] With the development of display technology and the upgrading of user needs, users are demanding narrower bezels and higher screen-to-body ratios for OLED display devices, leading to the increasingly widespread application of OLED display devices with high screen-to-body ratios. Currently, the low screen-to-body ratio of display devices is a problem that urgently needs to be solved. Summary of the Invention

[0004] The purpose of this disclosure is to provide a display device and its manufacturing method to solve the problem of low screen-to-body ratio in display devices.

[0005] To achieve the above objectives, the embodiments of this disclosure provide the following technical solutions:

[0006] On one hand, a display device is provided. The display device includes a display module, a frame, and a protective member. The display module includes an adjacent display panel and a bending member. The display panel and the bending member are connected. The bending member bends in a direction away from the display side of the display panel. The frame portion surrounds the display module. A gap exists between the display module and the frame. The protective member is located at least in the gap between the bending member and the frame.

[0007] In the aforementioned display device, the protective component at least provides protection for the bent component between it and the frame, and at least cushions the external pressure on the bent component, thereby improving the display device's pressure resistance and drop resistance. Furthermore, because the protective component protects the bent component between it and the frame, the distance between the bent component and the frame can be limited, thus reducing the area of ​​the non-light-emitting zone between the bent component and the frame in the display device and increasing the screen-to-body ratio.

[0008] In some embodiments, the bending member has at least one through hole. The protective member includes a first protective portion, a second protective portion, and a third protective portion. The first protective portion is located in the gap between the bending member and the frame, and covers the outer surface of the bending member. The second protective portion is located within the at least one through hole. The third protective portion is at least partially located between the bending member and the display panel. The second protective portion connects the first protective portion and the third protective portion.

[0009] In some embodiments, the bending member includes a plurality of metal traces. The at least one through-hole is formed on at least one of the plurality of metal traces.

[0010] In some embodiments, the plurality of metal traces include a first power line and a second power line. The at least one through-hole is formed on the first power line; or, the at least one through-hole is formed on the second power line.

[0011] In some embodiments, the number of through holes is multiple, and the multiple through holes are formed on the first power line and the second power line.

[0012] In some embodiments, the bending component further includes a protective layer. The protective layer is located on the side of the plurality of metal traces closest to the frame. The protective layer at least partially covers the outer surface of the plurality of metal traces.

[0013] In some embodiments, the distance between the bending member and the frame is less than or equal to 0.5 mm in a direction parallel to the display panel.

[0014] In some embodiments, the sum of the opening areas of the at least one through hole accounts for a proportion of the surface area of ​​the bent component that is greater than or equal to 2% and less than or equal to 18%.

[0015] In some embodiments, the opening area of ​​one of the through holes is greater than or equal to 0.07 mm2.

[0016] In some embodiments, at least a portion of the edge of the at least one through hole is arc-shaped.

[0017] In some embodiments, the display device further includes an optical sensor. The optical sensor is located between the bending member and the display panel. The orthographic projection of the optical sensor onto the outer surface of the frame at least partially covers the orthographic projection of the outline of the through hole onto the outer surface of the frame.

[0018] In some embodiments, the display device further includes a cover plate. The cover plate is located on the display side of the display panel and covers the display module. The bezel portion surrounds the cover plate. The protective member abuts against both the cover plate and the bezel.

[0019] In some embodiments, the material of the protective element includes at least one of polyimide, polyethylene terephthalate, or epoxy resin.

[0020] On the other hand, a method for manufacturing a display device is provided. The method includes: forming a display module. The display module includes adjacent display panels and a bending member. The display panels and the bending member are connected. The bending member is bent in a direction away from the display side of the display panels. A frame is formed. The frame partially surrounds the display module; a gap exists between the display module and the frame. A protective member is formed. The protective member is located at least in the gap between the bending member and the frame.

[0021] In the aforementioned method for manufacturing the display device, the protective component provides protection for the bent component between it and the frame, and buffers external pressure on the bent component, thereby improving the display device's pressure resistance and drop resistance. Furthermore, because the protective component protects the bent component between it and the frame, the distance between them can be reduced, thus decreasing the area of ​​the non-light-emitting region between the bent component and the frame, and increasing the screen-to-body ratio of the display device.

[0022] In some embodiments, forming the display module includes: forming at least one through-hole penetrating the substrate, and bending the portion having the at least one through-hole in a direction away from the display side of the display panel to form a bent component. Forming the protective component includes: forming the protective component by injection molding. The protective component includes a first protective portion, a second protective portion, and a third protective portion. The first protective portion is located in the gap between the bent component and the frame, and the first protective portion covers the outer surface of the bent component. The second protective portion is located within the at least one through-hole. The third protective portion is at least partially located between the bent component and the display panel. The second protective portion connects the first protective portion and the third protective portion.

[0023] In some embodiments, forming the protective member includes forming the protective member by injection molding, at least in the gap between the bent member and the frame. Attached Figure Description

[0038] The technical solutions in some embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0039] Unless the context otherwise requires, throughout the specification and claims, the term "comprising" is interpreted as open-ended and encompassing, meaning "including, but not limited to." In the description of the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiment," "example," or "some examples" are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this disclosure. The illustrative representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics mentioned may be included in any suitable manner in any one or more embodiments or examples.

[0040] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0041] In describing some embodiments, the terms "coupled" and "connected," and their derivative expressions, may be used. The term "connected" should be interpreted broadly; for example, a "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection via an intermediate medium. The term "coupled," for example, indicates that two or more components have direct physical or electrical contact. The term "coupled" or "communicatively coupled" may also refer to two or more components that do not have direct contact with each other but still cooperate or interact with each other. The embodiments disclosed herein are not necessarily limited to the content of this document.

[0042] "At least one of A, B and C" has the same meaning as "at least one of A, B or C", both including the following combinations of A, B and C: only A, only B, only C, combinations of A and B, combinations of A and C, combinations of B and C, and combinations of A, B and C.

[0043] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0044] As used herein, depending on the context, the term “if” may optionally be interpreted as meaning “when”, “in the event of”, “in response to determination”, or “in response to detection”. Similarly, depending on the context, the phrase “if it is determined that…” or “if [the stated condition or event] is detected” may optionally be interpreted as meaning “in the event of determination that…”, “in response to determination that…”, “when [the stated condition or event] is detected”, or “in response to the detection of [the stated condition or event]”.

[0045] The use of “applies to” or “configured to” in this article implies an open and inclusive language that does not preclude applicability to or configuration to devices that perform additional tasks or steps.

[0046] In addition, the use of “based on” implies openness and inclusivity, because processes, steps, calculations or other actions “based on” one or more of the stated conditions or values ​​may in practice be based on additional conditions or values ​​beyond those stated.

[0047] As used herein, “about,” “approximately,” or “approximately” includes the stated value and the average value within an acceptable range of deviation from the given value, wherein the acceptable range of deviation is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the given quantity (i.e., the limitations of the measurement system).

[0048] As used herein, “parallel,” “perpendicular,” and “equal” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallelism and approximate parallelism, where an acceptable range of deviation for approximate parallelism may be, for example, within 5°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where an acceptable range of deviation for approximate perpendicularity may also be, for example, within 5°; “equal” includes absolute equality and approximate equality, where an acceptable range of deviation for approximate equality may be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0049] It should be understood that when a layer or element is referred to as being on another layer or substrate, it can mean that the layer or element is directly on the other layer or substrate, or that there is an intermediate layer between the layer or element and the other layer or substrate.

[0050] This document describes exemplary embodiments with reference to cross-sectional views and / or plan views, which are idealized exemplary drawings. In the drawings, the thickness of layers and the area of ​​regions are enlarged for clarity. Therefore, variations in shape relative to the drawings are contemplated due to, for example, manufacturing techniques and / or tolerances. Thus, exemplary embodiments should not be construed as being limited to the shapes of the regions shown herein, but rather include shape deviations due to, for example, manufacturing processes. For example, etched areas shown as rectangular would typically have curved features. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of the areas of the device, nor are they intended to limit the scope of the exemplary embodiments.

[0051] Figure 1A and Figure 1B These are partial structural diagrams of the display device.

[0052] like Figure 1A and Figure 1B As shown, the display device 001 includes a display module 01, a frame 02, and a cover plate 03, with the frame 02 surrounding the display module 01 and the cover plate 03. The display module 01 includes adjacent and connected display panels 011 and bending components 012.

[0053] However, the inventors of this disclosure discovered through research that the bending component 012 lacks a supporting structure on its periphery and inside, making it prone to deformation and damage under pressure. To prevent damage to the bending component 012, a large reserved space is provided between the bending component 012 and the frame 02, resulting in a large distance between the bending component 012 and the frame 02 in the display device 001 (i.e., a large area of ​​the non-light-emitting region between the bending component 012 and the frame 02), thus leading to a low screen-to-body ratio in the display device 001.

[0054] Based on this, embodiments of the present disclosure provide a display device and a method for manufacturing the same, to overcome the aforementioned problems. These will be described in detail below.

[0055] Figure 2 This is a structural diagram of a display device according to some embodiments.

[0056] See Figure 2Some embodiments of this disclosure provide a display device 1000. The display device 1000 can be used to display static images or dynamic scenes. For example, the display device 1000 can be a small to medium-sized display device such as a tablet computer, smartphone, head-mounted display, car navigation unit, camera, in-vehicle center information display (CID), watch-type display device or other wearable device, personal digital assistant (PDA), portable multimedia player (PMP), or game console, as well as a medium to large-sized electronic device such as a television, external billboard, monitor, home appliance including a display screen, personal computer, or laptop computer. The above-described electronic devices represent only simple examples of applications of display devices, and therefore those skilled in the art will recognize that the display device 1000 can also be other electronic devices without departing from the spirit and scope of this disclosure.

[0057] For example, the above-mentioned display device 1000 may be a Liquid Crystal Display (LCD) display device, an OLED display device, a Quantum Dot Light Emitting Diode (QLED) display device, a Mini Light Emitting Diode (Mini LED) display device, or a Light Emitting Diode (Micro LED) display device, etc., without limitation.

[0058] The following embodiments of this disclosure are all based on the above-described display device 1000 as an OLED display device, but should be considered as not being limited to OLED display devices.

[0059] like Figure 2 As shown, the display device 1000 may include a display module 10 and a circuit board 200, with the display module 10 coupled to the circuit board 200. The circuit board 200 may be located on the backlight side of the display module 10 (i.e., the side opposite to the display side of the display module 10). For example, the circuit board 200 may be a flexible printed circuit board (FPC) or a printed circuit board. The circuit board 200 may provide light emission data signals, and the display module 10 emits light based on the light emission data signals provided by the circuit board 200.

[0060] The display side of the display module 10 can be understood as the side from which the human eye can receive and recognize the display light emitted by the display module 10.

[0061] Figure 3 This is a structural diagram of a display device according to some embodiments.

[0062] See Figure 2 and Figure 3 The display module 10 is a display component capable of emitting display light. The display module 10 can emit monochromatic light (light of a single color) or colored light. The display module 10 may include adjacent display panels 11 and bending components 12. The display panels 11 may include multiple light-emitting devices.

[0063] For example, the shape of the display panel 11 in the plan view may include a rectangle, a circle, an ellipse, a rhombus, a trapezoid, a square, or other shapes as needed for display.

[0064] Figure 4 for Figure 3 An enlarged view of area F of the display device.

[0065] Reference Figure 3 and Figure 4 As shown, the display device 1000 may also include a frame 20, a protective element 30, and a cover plate 40.

[0066] The border 20 can partially surround the display module 10, and there is a gap between the display module 10 and the border 20.

[0067] For example, the material of the frame 20 may include plastic (e.g., polycarbonate) or metal (e.g., aluminum alloy). The shape of the frame 20 can be flexibly designed according to actual needs and is not limited here.

[0068] The protective element 30 can be located in the gap between the display module 10 and the bezel 20. In this way, when the bezel 20 is installed around the display module 10, the protective element 30 can protect the display module 10, thereby improving the pressure resistance of the display device 1000.

[0069] The cover plate 40 can be located on the display side of the display panel 11, and the cover plate 40 can cover the display module 10. The frame 20 surrounds the cover plate 40. The protective member 30 can abut against the cover plate 40 and the frame 20 respectively. In this way, the cover plate 40 can protect the display module 10 on the display side, and the protective member 30 abuts against the cover plate 40 and the frame 20 respectively, so that the protective member 30 can fill the space between the display module 10, the cover plate 40 and the frame 20, which can improve the pressure resistance and drop resistance of the display device 1000.

[0070] For example, the cover plate 40 can be a flexible transparent cover plate 40, such as a flexible glass cover plate 40. The material of the cover plate 40 can be transparent polyimide (PI), polyethylene terephthalate (PET), or ultra-thin glass (UTG), etc., which have good flexibility, wear resistance, and light transmittance. For example, the cover plate 40 can be a single layer of transparent polyimide film, a single layer of ultra-thin glass, a double layer of transparent polyimide film structure bonded by optically transparent adhesive, a double layer structure of transparent polyimide film and polyethylene terephthalate film bonded by optically transparent adhesive, a double layer structure of transparent polyimide film and polyethylene terephthalate film bonded by thermoplastic polyurethanes (TPU), or a double layer structure of ultra-thin glass and polyethylene terephthalate film bonded by thermoplastic polyurethane elastomer, etc.

[0071] For example, the cover plate 40 can also be a rigid transparent cover plate 40, such as a rigid glass cover plate 40, a rigid quartz cover plate 40, etc.

[0072] The following are detailed descriptions of the display module 10 and the protective component 30 in the display device 1000.

[0073] like Figure 3 and Figure 4 As shown, the display module 10 can be a flexible display module 10 or a rigid display module 10. For example, the display module 10 can be a flexible OLED display module 10 or a flexible QLED display module 10, etc.

[0074] For example, the rigid display module 10 may include a rigid display panel 11 and a flexible bending component 12.

[0075] like Figure 4 As shown, the display module 10 may further include a substrate SUB. The substrate SUB may include a first substrate base SUB1, a second substrate base SUB2, and a third substrate base SUB3. The display panel 11 may include the first substrate base SUB1, which may be located on the side of the plurality of light-emitting devices near the third substrate base SUB3. The bending member 12 may include the second substrate base SUB2, which is bent away from the display side of the display panel 11. The second substrate base SUB2 may be connected to the first substrate base SUB1 and the third substrate base SUB3 respectively. The third substrate base SUB3 may be located on the side of the first substrate base SUB1 away from the display side, and the third substrate base SUB3 is substantially parallel to the first substrate base SUB1.

[0076] For example, the first substrate base SUB1 and the third substrate base SUB3 can be rigid substrate bases, and the second substrate base SUB2 can be a flexible substrate base.

[0077] For example, the substrate SUB can be a flexible substrate, wherein the first substrate base SUB1, the second substrate base SUB2 and the third substrate base SUB3 can be an integral structure connected to each other, and the second substrate base SUB2 can be thinned to facilitate bending.

[0078] In the direction perpendicular to the display panel 11, the size of the first substrate base SUB1 can be understood as the thickness of the first substrate base SUB1, and the size of the third substrate base SUB3 can be understood as the thickness of the third substrate base SUB3. In the direction perpendicular to the tangent of the bending member 12, the size of the second substrate base SUB2 can be understood as the thickness of the second substrate base SUB2. For example, the thickness of the second substrate base SUB2 is less than the thickness of the first substrate base SUB1, and the thickness of the second substrate base SUB2 is less than the thickness of the third substrate base SUB3.

[0079] In this way, when the second substrate base SUB2 is bent in the direction away from the display side of the display panel 11, the bending stress is small, and the second substrate base SUB2 is not easy to break, that is, the bending component 12 is not easy to break.

[0080] For example, the material of the flexible substrate may include flexible materials such as polyethylene terephthalate, polyimide, and cyclic olefin polymer (COP).

[0081] like Figure 3 and Figure 4 As shown, the display panel 11 and the bending component 12 are connected. For example, the display panel 11 and the bending component 12 can be an integral structure that is interconnected.

[0082] Among them, such as Figure 3 and Figure 4 As shown, the flexible circuit board 201 can be located on the side away from the display side of the display panel 11 (i.e., the backlight side of the display panel 11), and the bending member 12 can be coupled to the flexible circuit board 201. The flexible circuit board 201 can provide light emission data signals, which can be transmitted to the display panel 11 through the bending member 12. The display panel 11 emits light based on the light emission data signals provided by the flexible circuit board 201.

[0083] The bending member 12 can be bent in a direction away from the display side of the display panel 11. Understandably, the bending member 12 can be bent towards the backlight side of the display panel 11.

[0084] like Figure 3 As shown, the display module 10 may further include a driver chip 13. The driver chip 13 may be located on the backlight side of the display panel 11. The driver chip 13 may be coupled to the flexible circuit board 201 and the bending member 12, respectively. Understandably, one end of the bending member 12 is connected to the display panel 11; the other end of the bending member 12 is bent toward the backlight side of the display panel 11, and the other end of the bending member 12 is coupled to the driver chip 13 and the flexible circuit board 201, respectively.

[0085] For example, the bending component 12 may include a chip-on-film (COF) film. The COF can be bent to the backlight side of the display panel 11, so that the driving chip 13 can be disposed on the backlight side of the display panel 11, thereby reducing the width of the bezel 20 of the display device 1000 and increasing the screen-to-body ratio of the display device 1000.

[0086] For example, the bending component 12 may include a chip on panel (COP). The COP and the display panel 11 can be an integral structure that is interconnected. The COP can be bent as far as possible toward the backlight side of the display panel 11 to connect with the driver chip 13. The driver chip 13 can then be positioned as far away from the bezel 20 as possible on the backlight side of the display panel 11. Therefore, a narrow bezel 20 or even a bezel-less design can be achieved in the display device 1000, thereby increasing the screen-to-body ratio of the display device 1000.

[0087] Figure 5 This is a side view of a display device according to some embodiments. Figure 6A for Figure 5 Enlarged view of region G of the first power line. Figure 6B for Figure 5 An enlarged view of region H of the display device. Figure 7 This is a side view of a display device according to some embodiments.

[0088] In some embodiments, such as Figure 5 , Figure 6A and Figure 7 As shown, at least one through hole 121 may be provided on the bending component 12. This can reduce the bending stress of the bending component 12.

[0089] For example, the number of through holes 121 may include one or more. For instance, a through hole 121 may be provided at the middle position of the bent component 12. Or, for another example, a plurality of through holes 121 may be uniformly provided on the bent component 12.

[0090] In this way, the protective member 30 can extend through the through hole 121 and be disposed inside the through hole 121 and inside the bending member 12. The protective member 30 located inside can fit against the side surface of the bending member 12 to provide support, thereby improving the compressive strength of the bending member 12 and thus improving the compressive performance of the display device 1000.

[0091] In some examples, at least a portion of the edge of at least one through hole 121 may be arc-shaped. It is understood that the shape of a portion of the edge of at least one through hole 121 may be arc-shaped; or, the shape of the edge of at least one through hole 121 may be arc-shaped.

[0092] For example, such as Figure 5 and Figure 6A As shown, at least one through hole 121 can be circular in shape. It can be understood that one through hole 121 can be circular in shape; or, multiple through holes 121 can be circular in shape.

[0093] For example, such as Figure 7 As shown, at least one through hole 121 can be elliptical in shape. It can be understood that one through hole 121 can be elliptical in shape; or, multiple through holes 121 can be elliptical in shape.

[0094] For example, at least one through hole 121 can also be a shape in which one part of the edge is curved and the other part of the edge is straight, such as a rounded rectangle. Understandably, a through hole 121 can also be a shape in which one part of the edge is curved and the other part of the edge is straight; or, multiple through holes 121 can also be a shape in which one part of the edge is curved and the other part of the edge is straight.

[0095] In this way, the edge of the through hole 121 is relatively smooth, which can further reduce the bending stress of the bent component 12 and improve the strength of the bent component 12.

[0096] In some examples, the sum of the opening areas of at least one through hole 121 accounts for a percentage of the surface area of ​​the bent member 12 that is greater than or equal to 2% and less than or equal to 18% (e.g., 2%, 3%, 5%, 6%, 8%, 10%, 11%, 12%, 13%, 15%, 17%, or 18%). It can be understood that the sum of the opening areas of a plurality of through holes 121 accounts for a percentage of the surface area of ​​the bent member 12 that is greater than or equal to 2% and less than or equal to 18% (e.g., 2%, 3%, 5%, 6%, 8%, 10%, 11%, 12%, 13%, 15%, 17%, or 18%).

[0097] By limiting the ratio of the sum of the opening areas of at least one through hole 121 to the surface area of ​​the bending member 12 to a reasonable range, the rigidity and reliability of the bending member 12 can be guaranteed while improving its strength.

[0098] In some examples, the opening area of ​​a through-hole 121 can be greater than or equal to 0.07 mm. 2 (e.g., 0.07mm) 2 0.08mm 2 0.09mm 2 0.10mm 2 0.12mm 2 0.15mm 2 Or 0.20mm 2 ).

[0099] By limiting the opening area of ​​a single through hole 121, the protective member 30 can be easily extended into the interior of the bent member 12 through the through hole 121, and the strength of the bent member 12 at the opening of the single through hole 121 can be avoided to be too low.

[0100] In some embodiments, such as Figure 5 , Figure 6B and Figure 7 As shown, the bending component 12 may also include multiple spaced metal traces 14. The multiple metal traces 14 may be located outside the second substrate base SUB2, and the metal traces 14 are also bent in a direction away from the display side of the display panel 11.

[0101] The through hole 121 can be formed on the metal trace 14. In this way, since the metal trace 14 has high strength, the through hole 121 will not affect the signal transmission function of the metal trace 14. Furthermore, the outline of the through hole 121 is not easily deformed by pressure, which can reduce the bending stress on the metal trace 14 and ensure the strength of the bent component 12.

[0102] For example, such as Figure 5 and Figure 7 As shown, the multiple metal traces 14 may include multiple first power lines 141 and multiple second power lines 142 spaced apart from each other. Both the first power lines 141 and the second power lines 142 may be bent in a direction away from the display side of the display panel 11.

[0103] For example, both the first power line 141 and the second power line 142 can be designed with non-uniform widths. Understandably, the dimensions (i.e., the widths of different parts of the first power line 141) can be different in the extension direction perpendicular to the first power line 141; similarly, the dimensions (i.e., the widths of different parts of the second power line 142) can also be different in the extension direction perpendicular to the second power line 142.

[0104] The use of non-uniform widths for the first power line 141 and the second power line 142 facilitates the layout of the metal wiring 14. Furthermore, through holes can be located in the wider portion of the first power line 141, or in the wider portion of the second power line 142, ensuring the strength of the bent component 12.

[0105] For example, the multiple metal traces 14 may also include touch signal lines. The touch signal lines may be located between adjacent second power lines 142. The width of the first power line 141 may be greater than the width of the second power line 142, and the width of the first power line 141 may be greater than the width of the touch signal lines. A through-hole 121 may be formed on the first power line 141. This prevents the through-hole 121 from reducing the strength of the touch signal lines and the second power lines 142, thus ensuring the functionality of the touch signal lines and the second power lines 142.

[0106] At least one via 121 may be formed on at least one metal trace 14. It is understood that a via 121 may be formed on one metal trace 14; or, a via 121 may be formed on multiple metal traces 14; or, multiple vias 121 may be formed on one metal trace 14.

[0107] In this way, the protective member 30 can be extended into at least one through hole 121 and inside the bending member 12, thereby improving the compressive strength of the bending member 12 and thus improving the compressive performance of the display device 1000.

[0108] In some examples, a via 121 can be formed on a metal trace 14.

[0109] For example, a through hole 121 may be formed on a first power line 141.

[0110] For example, a through-hole 121 may be formed on a second power line 142.

[0111] In this way, the protective member 30 can be extended into a through hole 121, and the protective member 30 can also extend into the bent member 12 through a through hole 121.

[0112] In some examples, such as Figure 5 and Figure 7 As shown, a through hole 121 can be formed on multiple metal traces 14.

[0113] For example, a through-hole 121 may be formed on an adjacent first power line 141 and a second power line 142. Understandably, the first power line 141 may include a portion of the outline of the through-hole 121, and the second power line 142 adjacent to the first power line 141 may also include a portion of the outline of the through-hole 121.

[0114] In this way, the opening area of ​​a through hole 121 is relatively large, which allows the protective element 30 formed within the through hole 121 to have a larger volume, thereby improving the protective and supporting effect of the protective element 30 on the bent component 12. Furthermore, part of the outline of the through hole 121 is located on the first power line 141 and the second power line 142, so it will not affect the signal transmission function of the first power line 141 and the second power line 142.

[0115] In some examples, such as Figure 5 and Figure 7 As shown, multiple through holes 121 can be formed on a single metal trace 14.

[0116] For example, such as Figure 6A As shown, multiple through holes 121 can be formed on a first power line 141.

[0117] For example, multiple through holes 121 may be formed on a second power line 142.

[0118] In this way, the protective member 30 can be extended into the multiple through holes 121, and the protective member 30 can also extend into the interior of the bent member 12 through the multiple through holes 121.

[0119] In some examples, there are multiple vias 121, and multiple vias 121 can be formed on the first power line 141 and the second power line 142.

[0120] In this way, the outline of the through hole 121 can be located on the first power line 141 and the second power line 142 without affecting the signal transmission function of the first power line 141 and the second power line 142. Furthermore, the protective member 30 can be extended into the multiple through holes 121, and the protective member 30 can also extend into the interior of the bent component 12 through the multiple through holes 121.

[0121] Figure 8 This is a partial structural diagram of a display device according to some embodiments.

[0122] In some embodiments, such as Figure 8As shown, the display device 1000 may further include an optical sensor 50. The optical sensor 50 may be located between the bending member 12 and the display panel 11. For example, the optical sensor 50 may include a fingerprint recognition sensor or an image recognition sensor, etc.

[0123] The orthographic projection of the optical sensor 50 onto the outer surface of the frame 20 at least partially covers the orthographic projection of the outline of the through hole 121 onto the outer surface of the frame 20. It can be understood that the orthographic projection of the optical sensor 50 onto the outer surface of the frame 20 may partially cover the orthographic projection of the outline of the through hole 121 onto the outer surface of the frame 20; or, the orthographic projection of the optical sensor 50 onto the outer surface of the frame 20 may cover the orthographic projection of the outline of the through hole 121 onto the outer surface of the frame 20.

[0124] In this way, fingerprint information or other image information can be transmitted to the optical sensor 50 at least through the overlapping part of the optical sensor 50 and the through hole 121. The optical sensor 50 can collect the fingerprint information or other image information to realize the recognition and processing of the fingerprint information or other image information.

[0125] In some examples, the orthographic projection of the optical sensor 50 onto the outer surface of the frame 20 may coincide with the orthographic projection of the outline of the through hole 121 onto the outer surface of the frame 20.

[0126] In this way, fingerprint information or other image information can be transmitted to the optical sensor 50 through the overlapping part of the optical sensor 50 and the through hole 121. The optical sensor 50 can collect the fingerprint information or other image information to realize the recognition and processing of the fingerprint information or other image information.

[0127] In some examples, the orthographic projection of the optical sensor 50 onto the outer surface of the frame 20 can cover the orthographic projection of the outline of the through hole 121 onto the outer surface of the frame 20.

[0128] In this way, fingerprint information or other image information can be transmitted to optical sensor 50 through through hole 121. Optical sensor 50 can collect the fingerprint information or other image information to realize the recognition and processing of fingerprint information or other image information.

[0129] In some embodiments, such as Figure 8 As shown, the bending component 12 may also include a protective layer 122. The protective layer 122 may be located on the side of the multiple metal traces 14 near the frame 20.

[0130] For example, the material of the protective layer 122 may include materials such as polyimide or polyethylene terephthalate to ensure that the light transmittance of the protective layer 122 is high.

[0131] The protective layer 122 may at least partially cover the outer surface of the plurality of metal traces 14. It is understood that the protective layer 122 may partially cover the outer surface of the plurality of metal traces 14; or, the protective layer 122 may cover the outer surface of the plurality of metal traces 14.

[0132] The protective layer 122 can buffer and absorb at least part of the pressure from the outside of the multiple metal traces 14, thereby reducing the damage of at least part of the external pressure to the multiple metal traces 14 during bending or operation. Therefore, the protective layer 122 can protect the bent component 12 and improve the pressure resistance and reliability of the display device 1000.

[0133] In some examples, the protective layer 122 may partially cover the outer surface of multiple metal traces 14.

[0134] In this way, the protective layer 122 can buffer and absorb the external pressure at the overlapping part of the multiple metal traces 14 and the protective layer 122, thereby reducing some of the damage to the multiple metal traces 14 caused by external pressure during bending or operation.

[0135] In some examples, the protective layer 122 may cover the outer surface of multiple metal traces 14.

[0136] In this way, the protective layer 122 can buffer and absorb the pressure from the outside of the multiple metal traces 14, thereby reducing the damage to the multiple metal traces 14 caused by external pressure during bending or operation.

[0137] In some embodiments, such as Figure 8 As shown, in the direction parallel to the display panel 11, the distance d between the bending member 12 and the frame 20 can be less than or equal to 0.5 mm (e.g., 0.1 mm, 0.2 mm, 0.3 mm, 0.35 mm, 0.4 mm, 0.45 mm or 0.5 mm).

[0138] Since the protective component 30 can protect the bent component 12 between the bent component 12 and the frame 20, the distance d between the bent component 12 and the frame 20 can be limited to a small range, thereby reducing the area of ​​the non-light-emitting area between the bent component 12 and the frame 20 in the display device 1000 and increasing the screen ratio of the display device 1000.

[0139] In some embodiments, such as Figure 4 and Figure 8As shown, the protective member 30 may be located at least in the gap between the bent member 12 and the frame 20. It can be understood that the protective member 30 may be located in the gap between the bent member 12 and the frame 20; or, the protective member 30 may be located in the gap between the bent member 12 and the frame 20, and the protective member 30 may also be located inside the bent member 12.

[0140] In this way, the protective component 30 can at least protect the bent component 12 between the bent component 12 and the frame 20, and can at least buffer the external pressure on the bent component 12, thereby improving the pressure resistance and drop resistance of the display device 1000. Furthermore, since the protective component 30 can protect the bent component 12 between the bent component 12 and the frame 20, the distance between the bent component 12 and the frame 20 can be reduced, thereby reducing the area of ​​the non-light-emitting region between the bent component 12 and the frame 20 in the display device 1000 and increasing the screen-to-body ratio of the display device 1000.

[0141] In some examples, the protective element 30 may be located in the gap between the bent part 12 and the frame 20.

[0142] In this way, the protective component 30 can protect the bent component 12 between the bent component 12 and the frame 20. The protective component 30 can buffer the external pressure on the bent component 12, thereby improving the pressure resistance and drop resistance of the display device 1000.

[0143] In some examples, such as Figure 4 and Figure 8 As shown, the protective element 30 may include a first protective part 31, a second protective part 32, and a third protective part 33. For example, the first protective part 31, the second protective part 32, and the third protective part 33 may be an integral structure that is interconnected.

[0144] The first protective part 31 can be located in the gap between the bent component 12 and the frame 20, and the first protective part 31 can cover the outer surface of the bent component 12. In this way, the first protective part 31 can protect the bent component 12 between the bent component 12 and the frame 20, and the first protective part 31 can buffer the external pressure on the bent component 12, thereby improving the pressure resistance and drop resistance of the display device 1000.

[0145] For example, the first protective part 31 can abut against the cover plate 40 and the frame 20 respectively. In this way, the first protective part 31 can fill the space between the bent part 12, the cover plate 40 and the frame 20, and the first protective part 31 can also protect the bent part 12 between the bent part 12 and the cover plate 40.

[0146] For example, such as Figure 4 and Figure 8 As shown, the display module 10 may further include a polarizer 16. The polarizer 16 may be located on the display side of the display panel 11. The first protective part 31 may abut against the polarizer 16, and the first protective part 31 may also protect the polarizer 16.

[0147] The second protective part 32 may be located within at least one through hole 121. It is understood that the second protective part 32 may be located within one through hole 121; or, the second protective part 32 may be located within multiple through holes 121.

[0148] The second protective part 32 is connected to the first protective part 31 and the third protective part 33 respectively. In this way, while reducing the bending stress of the bent component 12, the second protective part 32 can provide a certain support for the bent component 12 within the through hole 121, thereby improving the strength and reliability of the bent component 12.

[0149] The third protective portion 33 is at least partially located between the bending member 12 and the display panel 11. It is understood that the third protective portion 33 may be located inside the bending member 12; or, the third protective portion 33 may be located inside the bending member 12 and between the first substrate base SUB1 and the third substrate base SUB3.

[0150] In this way, the third protective part 33 can support the bending part 12 in at least a part of the interior of the bending part 12, which can further improve the strength and reliability of the bending part 12, thereby further improving the pressure resistance and drop resistance of the display device 1000.

[0151] For example, the orthographic projection of the third protective portion 33 onto a plane parallel to the display panel 11 may coincide with the orthographic projection of the inner contour of the bent member 12 onto a plane parallel to the display panel 11. It can be understood that the third protective portion 33 may be located in a portion of the interior of the bent member 12.

[0152] In this way, at the overlapping part of the third protective part 33 and the bending part 12, the third protective part 33 can provide support for the bending part 12 at the overlapping part inside the bending part 12, thereby improving the strength and reliability of the bending part 12.

[0153] For example, the orthographic projection of the third protective portion 33 onto a plane parallel to the display panel 11 can coincide with the orthographic projection of the inner contour of the bent member 12 onto a plane parallel to the display panel 11. It can be understood that the third protective portion 33 can be located in the entire area inside the bent member 12.

[0154] In this way, the third protective part 33 can support the bending part 12 inside the bending part 12, which can greatly improve the strength and reliability of the bending part 12, thereby greatly improving the pressure resistance and drop resistance of the display device 1000.

[0155] For example, such as Figure 4 and Figure 8 As shown, the orthographic projection of the third protective part 33 on a plane parallel to the display panel 11 can cover the orthographic projection of the inner contour of the bent part 12 on a plane parallel to the display panel 11, as well as the orthographic projection of part of the first substrate base SUB1 on a plane parallel to the display panel 11.

[0156] In this way, the third protective part 33 can support the bending part 12 inside the bending part 12, and the third protective part 33 can also support part of the display panel 11 between the first substrate base SUB1 and the third substrate base SUB3, thereby greatly improving the pressure resistance and drop resistance of the display device 1000.

[0157] For example, such as Figure 4 and Figure 8 As shown, the display device 1000 may further include a support member 17. The support member 17 may be located between the first substrate base SUB1 and the third substrate base SUB3, and the third protective portion 33 may abut against the support member 17.

[0158] In this way, between the first substrate base SUB1 and the third substrate base SUB3, the third protective part 33 can support a portion of the display panel 11, and the support member 17 can support another portion of the display panel 11, thereby improving the pressure resistance and drop resistance of the display device 1000.

[0159] In some embodiments, the material of the protective element 30 may include at least one of polyimide, polyethylene terephthalate, or epoxy resin. For example, the material of the protective element 30 may include polyimide. As another example, the material of the protective element 30 may include epoxy resin. Yet another example, the material of the protective element 30 may include both polyimide and polyethylene terephthalate.

[0160] The material of the protective component 30 has high light transmittance, viscosity and fluidity, which makes the protective component 30 have high light transmittance. Furthermore, the protective component 30 can be formed into an integral structure through injection molding, which makes the protective component 30 provide better protection for the bent component 12.

[0161] In summary, in the display device 1000 and the display device provided in this disclosure, the protective member 30 can at least protect the bent member 12 between the bent member 12 and the frame 20, and the protective member 30 can at least buffer the external pressure on the bent member 12, thereby improving the pressure resistance and drop resistance of the display device 1000. Furthermore, since the protective member 30 can protect the bent member 12 between the bent member 12 and the frame 20, the distance between the bent member 12 and the frame 20 can be limited, thereby reducing the area of ​​the non-light-emitting area between the bent member 12 and the frame 20 in the display device 1000 and increasing the screen-to-body ratio of the display device 1000.

[0162] Figures 9-11 These are flowcharts illustrating methods for manufacturing display devices according to some embodiments.

[0163] This disclosure also provides a method for manufacturing a display device 1000 according to some embodiments. This method for manufacturing the display device 1000 can produce the display device 1000 as described in any of the above embodiments. Figure 9 As shown, the method for manufacturing the display device 1000 may include steps S100 to S300.

[0164] Step S100: Forming a display module 10. The display module 10 includes adjacent display panels 11 and bending members 12. The display panels 11 and bending members 12 are connected. The display panels 11 may include multiple light-emitting devices. The bending members 12 are bent in a direction away from the display side of the display panels 11.

[0165] The display module 10 can be a flexible display module 10 or a rigid display module 10.

[0166] For example, the display module 10 may be a flexible OLED display module 10 or a flexible QLED display module 10, etc.

[0167] For example, the rigid display module 10 may include a rigid display panel 11 and a flexible bending component 12.

[0168] like Figure 3 and Figure 4As shown, the display module 10 may further include a substrate SUB. The substrate SUB may include a first substrate base SUB1, a second substrate base SUB2, and a third substrate base SUB3. The display panel 11 may include the first substrate base SUB1, which may be located on the side of the plurality of light-emitting devices near the third substrate base SUB3. The bending member 12 may include the second substrate base SUB2, which is bent away from the display side of the display panel 11. The second substrate base SUB2 may be connected to the first substrate base SUB1 and the third substrate base SUB3 respectively. The third substrate base SUB3 may be located on the side of the first substrate base SUB1 away from the display side, and the third substrate base SUB3 is substantially parallel to the first substrate base SUB1.

[0169] For example, the first substrate base SUB1, the second substrate base SUB2 and the third substrate base SUB3 can be an integral structure that is interconnected. The second substrate base SUB2 can be thinned to facilitate bending.

[0170] The specific structural features of the display module 10 have been described in detail above and will not be repeated here.

[0171] In some examples, such as Figure 5 and Figure 7 As shown, the bending component 12 may also include multiple metal traces 14. The multiple metal traces 14 may be located outside the second substrate base SUB2, and the multiple metal traces 14 are also bent in a direction away from the display side of the display panel 11.

[0172] For example, the multiple metal traces 14 may include multiple first power lines 141 and multiple second power lines 142 spaced apart from each other. Both the first power lines 141 and the second power lines 142 may be bent in a direction away from the display side of the display panel 11.

[0173] For example, both the first power line 141 and the second power line 142 can be designed with non-equal widths. The use of non-equal widths for the first power line 141 and the second power line 142 can facilitate the layout of the metal traces 14.

[0174] Step S100 may include: forming a substrate SUB. On one side of the substrate SUB, a plurality of metal traces 14 and a plurality of light-emitting devices are sequentially formed, and the first substrate base SUB1 and the plurality of light-emitting devices form a display panel 11. Then, the plurality of metal traces 14 and the second substrate base SUB2, which cover the surface of the second substrate base SUB2, are bent in a direction away from the display side of the display panel 11 to form a bending member 12.

[0175] For example, the bending component 12 may include a chip-on-film (COF) film. The COF can be bent to the backlight side of the display panel 11, so that the driving chip 13 can be disposed on the backlight side of the display panel 11, thereby reducing the width of the bezel 20 of the display device 1000 and increasing the screen-to-body ratio of the display device 1000.

[0176] For example, the bending component 12 may include a chip on panel (COP). The COP and the display panel 11 can be an integral structure that is interconnected. The COP can be bent as far as possible toward the backlight side of the display panel 11 to connect with the driver chip 13. The driver chip 13 can then be positioned as far away from the bezel 20 as possible on the backlight side of the display panel 11. Therefore, a narrow bezel or even a bezel-less display device 1000 can be achieved, thereby increasing the screen-to-body ratio of the display device 1000.

[0177] In some examples, such as Figure 10 As shown, step S100 may also include step S110.

[0178] Step S110: Form at least one through hole 121 through the substrate SUB, and bend the portion having the through hole 121 toward the display side away from the display panel 11 to form a bending member 12.

[0179] For example, step S110 may include forming at least one through hole 121 through the substrate SUB by dry etching or laser drilling.

[0180] For example, the number of through holes 121 may include one or more. For instance, a through hole 121 may be provided at the middle position of the bent component 12. Or, for another example, a plurality of through holes 121 may be uniformly provided on the bent component 12.

[0181] In this way, the protective member 30 can extend through the through hole 121 and be disposed inside the through hole 121 and inside the bending member 12. The protective member 30 located inside can fit against the side surface of the bending member 12 to provide support, thereby improving the compressive strength of the bending member 12 and thus improving the compressive performance of the display device 1000.

[0182] For example, at least a portion of the edge of at least one through hole 121 may be arc-shaped. It is understood that a portion of the edge of at least one through hole 121 may be arc-shaped; or, the edges of at least one through hole 121 may all be arc-shaped.

[0183] For example, such as Figure 5 and Figure 6AAs shown, at least one through hole 121 can be circular in shape. It can be understood that one through hole 121 can be circular in shape; or, multiple through holes 121 can be circular in shape.

[0184] For example, such as Figure 7 As shown, at least one through hole 121 can be elliptical in shape. It can be understood that one through hole 121 can be elliptical in shape; or, multiple through holes 121 can be elliptical in shape.

[0185] For example, at least one through hole 121 can also be a shape in which one part of the edge is curved and the other part of the edge is straight, such as a rounded rectangle. Understandably, a through hole 121 can also be a shape in which one part of the edge is curved and the other part of the edge is straight; or, multiple through holes 121 can also be a shape in which one part of the edge is curved and the other part of the edge is straight.

[0186] In this way, the edge of the through hole 121 is relatively smooth, which can further reduce the bending stress of the bent component 12 and improve the strength of the bent component 12.

[0187] For example, at least one via 121 may be formed on at least one metal trace 14. It is understood that a via 121 may be formed on one metal trace 14; or, a via 121 may be formed on multiple metal traces 14; or, multiple vias 121 may be formed on one metal trace 14.

[0188] For example, after forming multiple metal traces 14, step S110 may include: creating at least one through hole 121 on at least one metal trace 14 by dry etching or laser drilling.

[0189] Thus, because the metal trace 14 has high strength, the through hole 121 is formed on the metal trace 14. The outline of the through hole 121 is not easily deformed by pressure, which can reduce the bending stress on the metal trace 14 and ensure the strength of the bent component 12. Furthermore, the protective member 30 can extend and be disposed within at least one through hole 121 and inside the bent component 12, thereby improving the compressive strength of the bent component 12 and thus improving the compressive strength of the display device 1000.

[0190] Step S200: Form border 20. Border 20 partially surrounds display module 10. There is a gap between display module 10 and border 20.

[0191] For example, the material of the frame 20 may include plastic (e.g., polycarbonate) or metal (e.g., aluminum alloy). The shape of the frame 20 can be flexibly designed according to actual needs and is not limited here.

[0192] For example, if the frame 20 is made of plastic, step S200 may include forming the frame 20 by injection molding.

[0193] For example, if the frame 20 is made of metal, step S200 may include forming the frame 20 by a stamping process.

[0194] Step S300: Form the protective member 30. The protective member 30 is located at least in the gap between the bent member 12 and the frame 20.

[0195] Understandably, the protective element 30 may be located in the gap between the bent member 12 and the frame 20; or, the protective element 30 may be located in the gap between the bent member 12 and the frame 20, and the protective element 30 may also be located inside the bent member 12.

[0196] In this way, the protective component 30 can at least protect the bent component 12 between the bent component 12 and the frame 20, and can at least buffer the external pressure on the bent component 12, thereby improving the pressure resistance and drop resistance of the display device 1000. Furthermore, since the protective component 30 can protect the bent component 12 between the bent component 12 and the frame 20, the distance between the bent component 12 and the frame 20 can be reduced, thereby reducing the area of ​​the non-light-emitting region between the bent component 12 and the frame 20 in the display device 1000 and increasing the screen-to-body ratio of the display device 1000.

[0197] In some examples, such as Figure 10 As shown, step S300 may include step S310.

[0198] Step S310: Form the protective part 30 by injection molding process.

[0199] like Figure 4 and Figure 8 As shown, the protective element 30 may include a first protective part 31, a second protective part 32, and a third protective part 33. For example, the first protective part 31, the second protective part 32, and the third protective part 33 may be an integral structure that is interconnected.

[0200] The first protective part 31 can be located in the gap between the bent component 12 and the frame 20, and the first protective part 31 can cover the outer surface of the bent component 12. In this way, the first protective part 31 can protect the bent component 12 between the bent component 12 and the frame 20, and the first protective part 31 can buffer the external pressure on the bent component 12, thereby improving the pressure resistance and drop resistance of the display device 1000.

[0201] The second protective part 32 may be located within at least one through hole 121. It is understood that the second protective part 32 may be located within one through hole 121; or, the second protective part 32 may be located within multiple through holes 121.

[0202] The second protective part 32 is connected to the first protective part 31 and the third protective part 33 respectively. In this way, while reducing the bending stress of the bent component 12, the second protective part 32 can provide a certain support for the bent component 12 within the through hole 121, thereby improving the strength and reliability of the bent component 12.

[0203] The third protective portion 33 is at least partially located between the bending member 12 and the display panel 11. It is understood that the third protective portion 33 may be located inside the bending member 12; or, the third protective portion 33 may be located inside the bending member 12 and between the first substrate base SUB1 and the third substrate base SUB3.

[0204] In this way, the third protective part 33 can support the bending part 12 in at least a part of the interior of the bending part 12, which can further improve the strength and reliability of the bending part 12, thereby further improving the pressure resistance and drop resistance of the display device 1000.

[0205] For example, the orthographic projection of the third protective portion 33 onto a plane parallel to the display panel 11 may coincide with the orthographic projection of the inner contour of the bent member 12 onto a plane parallel to the display panel 11. It can be understood that the third protective portion 33 may be located in a portion of the interior of the bent member 12.

[0206] In this way, at the overlapping part of the third protective part 33 and the bending part 12, the third protective part 33 can provide support for the bending part 12 at the overlapping part inside the bending part 12, thereby improving the strength and reliability of the bending part 12.

[0207] For example, the orthographic projection of the third protective portion 33 onto a plane parallel to the display panel 11 can coincide with the orthographic projection of the inner contour of the bent member 12 onto a plane parallel to the display panel 11. It can be understood that the third protective portion 33 can be located in the entire area inside the bent member 12.

[0208] In this way, the third protective part 33 can support the bending part 12 inside the bending part 12, which can greatly improve the strength and reliability of the bending part 12, thereby greatly improving the pressure resistance and drop resistance of the display device 1000.

[0209] For example, the orthographic projection of the third protective part 33 on a plane parallel to the display panel 11 can cover the orthographic projection of the inner contour of the bent part 12 on a plane parallel to the display panel 11, as well as the orthographic projection of a portion of the first substrate base SUB1 on a plane parallel to the display panel 11.

[0210] In this way, the third protective part 33 can support the bending part 12 inside the bending part 12, and the third protective part 33 can also support part of the display panel 11 between the first substrate base SUB1 and the third substrate base SUB3, thereby greatly improving the pressure resistance and drop resistance of the display device 1000.

[0211] In some embodiments, such as Figure 11 As shown, step S300 may include step S311.

[0212] Step S311: The protective element 30 is formed by injection molding at least in the gap between the bent part 12 and the frame 20.

[0213] In some examples, where no through hole 121 is provided on the bent component 12, step S311 may include: first forming a sealed space between the bent component 12 and the frame 20, and then filling the sealed space with protective material, thereby forming a protective element 30 in the gap between the bent component 12 and the frame 20 by injection molding.

[0214] In this way, the protective component 30 can protect the bent component 12 between the bent component 12 and the frame 20. The protective component 30 can buffer the external pressure on the bent component 12, thereby improving the pressure resistance and drop resistance of the display device 1000.

[0215] In other examples, such as Figure 4 and Figure 8 As shown, when a through hole 121 is provided on the bent component 12, step S311 may include: filling the gap between the bent component 12 and the frame 20 with protective material through an injection molding process, and injecting the protective material into the interior of the bent component 12 through at least one through hole 121. A first protective portion 31 may be formed between the bent component 12 and the frame 20, a second protective portion 32 may be formed within the at least one through hole 121, and a third protective portion 33 may be formed inside the bent component 12. The first protective portion 31, the second protective portion 32, and the third protective portion 33 form an integral protective component 30.

[0216] For example, the protective material may include at least one of polyimide, polyethylene terephthalate, or epoxy resin. For instance, the protective material may include polyimide. As another example, the protective material may include epoxy resin. Yet another example, the protective material may include both polyimide and polyethylene terephthalate.

[0217] The protective material has high light transmittance, viscosity, and fluidity, resulting in high light transmittance of the formed protective part 30. Furthermore, the protective part 30 can be formed into an integral structure through injection molding, which makes the protective part 30 provide better protection for the bent component 12.

[0218] Thus, the first protective part 31 can protect the bent component 12 between the bent component 12 and the frame 20, and can buffer the external pressure on the bent component 12; the second protective part 32 can provide some support for the bent component 12 within at least one through hole 121; and the third protective part 33 can provide support for the bent component 12 in at least a portion of its interior area. The protective member 30 can improve the strength and reliability of the bent component 12, thereby improving the pressure resistance and drop resistance of the display device 1000. Furthermore, by forming the frame 20 first and then the protective member 30, the shape and size of the protective member 30 can be defined by the frame 20, thereby reducing the processing precision of the injection mold used to form the protective member 30.

[0219] Figure 12 This is a structural diagram of a display device and an injection mold according to some embodiments. Figure 13 This is a process diagram of injection molding to form a protective part according to some embodiments. Figure 14 This is a flowchart illustrating a method for manufacturing a protective element in a display device according to some embodiments.

[0220] In other embodiments, such as Figure 3 and Figure 12 As shown, after step S100, the process may include: forming a cover plate 40 and fixing the cover plate 40 to the display side of the display panel 11. The cover plate 40 can cover the display module 10. The specific structure and material of the cover plate 40 have been described in detail above and will not be repeated here.

[0221] Then, step S300 is performed, which may include: forming an injection mold 60. For example... Figure 12 and Figure 13As shown, the injection mold 60 may include a first mold base 61, a first mold core 62, a second mold core 63, a second mold base 64, a feed channel 65, an discharge channel 66, and an air intake channel 67. The first mold core 62 is embedded inside the first mold base 61, and the second mold core 63 is embedded inside the second mold base 64. The first mold base 61 and the second mold base 64 abut against each other, and the first mold core 62 and the second mold core 63 abut against each other, together forming a cavity for receiving the display module 10 and the cover plate 40. The cover plate 40 may be embedded inside the second mold core 63, and the first mold core 62 and the cover plate 40 together form the cavity. The feed channel 65, the discharge channel 66, and the air intake channel 67 are all disposed in the first mold base 61 and the first mold core 62. The air intake channel 67 is located between the feed channel 65 and the discharge channel 66. The feed channel 65 connects to the bending component 12.

[0222] After that, as Figures 12-14 As shown, the display module 10 is tested for illumination and size, and the display module 10 and the cavity of the injection mold 60 are cleaned. For example, dry ice cleaning, alcohol cleaning or plasma cleaning can be used to clean the surface of the display module 10 and the cover plate 40 as well as the cavity of the injection mold 60.

[0223] Next, adhesive is applied to the cavity formed by the first mold core 62 and the cover plate 40 and cured to create a sealed space. For example, the adhesive can be cured by baking it in a forced-air oven.

[0224] Then, the protective material is vacuum-injected into the cavity between the first mold core 62 and the cover plate 40 through the feeding channel 65 until the excess protective material overflows from the discharge channel 66.

[0225] Next, the protective material is cured. For example, the protective material can be baked in a forced-air oven to cure it. After the protective material has cured, any remaining protective material in the feed channel 65 and the discharge channel 66 is removed.

[0226] Subsequently, air is blown into the injection mold 60 through the air intake channel 67, causing the first mold core 62 and the second mold core 63 to be demolded. Simultaneously, the demolding of the first mold core 62 and the second mold core 63 removes residual protective material from the feed channel 65 and the discharge channel 66. The remaining protective material in the cavity between the first mold core 62 and the cover plate 40 undergoes secondary baking and curing, inspection, (using a grinding machine) deburring, and (using an air gun) dust removal and cleaning to form the protective component 30.

[0227] When a through hole 121 is provided in the bent component 12, protective material is filled into the cavity between the first mold core 62 and the cover plate 40 through the above-described injection molding process. The protective material can be injected into the interior of the bent component 12 through at least one through hole 121, forming a first protective part 31 between the bent component 12 and the first mold core 62, a second protective part 32 within the at least one through hole 121, and a third protective part 33 within the bent component 12. The first protective part 31, the second protective part 32, and the third protective part 33 are an integral structure, forming an integral protective component 30.

[0228] Next, a border 20 is formed, and the border 20 partially surrounds the protective element 30 and the cover plate 40.

[0229] In this way, the protective component 30 is formed first and then the frame 20 is formed. During the process of assembling the frame 20 on the outside of the display module 10, the protective component 30 can prevent the display module 10 from being damaged by pressure, thereby improving the manufacturing yield of the display device 1000.

[0230] In summary, the method for manufacturing the display device provided in this disclosure results in a display device 1000 in which the protective member 30 at least provides protection for the bent component 12 between the bent component 12 and the frame 20. The protective member 30 at least buffers the external pressure on the bent component 12, thereby improving the pressure resistance and drop resistance of the display device 1000. Furthermore, since the protective member 30 provides protection for the bent component 12 between the bent component 12 and the frame 20, the distance between the bent component 12 and the frame 20 can be reduced, thereby decreasing the area of ​​the non-light-emitting region between the bent component 12 and the frame 20 in the display device 1000 and increasing the screen-to-body ratio of the display device 1000.

[0231] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
