Description

Technical Field

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

[0002] With the continuous development of display technology, narrow bezel design of display devices has gradually become one of the main trends in the industry. Narrow bezels can significantly improve the aesthetics of products, increase the effective display area, and bring users a better visual immersion experience. However, while narrowing the bezels of display devices, their strength is often insufficient for practical use. How to ensure sufficient mechanical reliability of the bezel while achieving narrow bezels is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0003] The purpose of the embodiments disclosed herein is to provide a display module and display device that achieves a narrow bezel on the display screen while meeting the requirements for bezel strength.

[0004] To achieve the above objectives, the embodiments of this disclosure provide the following technical solutions: On one hand, a display module is provided. The display module includes a display panel, a cover plate, a first frame, and a first support plate. The display panel includes a display portion, a folding portion, and a bent portion located between the display portion and the folding portion; the display portion has a display side and a non-display side, and the folding portion is located on the non-display side; the cover plate is located on the display side; the first frame at least covers the bent portion and is connected to the cover plate; the first support plate is located on the side of the first frame away from the cover plate and is connected to the first frame; in its orthographic projection onto the cover plate, the first support plate does not extend beyond the boundary of the folding portion away from the bent portion.

[0005] In the aforementioned display module, the first frame covers the bent portion, effectively protecting the fragile bent portion of the display panel. Simultaneously, a first support plate is positioned on the side of the first frame away from the cover plate, providing rigid support and reducing the risk of deformation and damage to the bent portion under external forces. Furthermore, in its orthographic projection onto the cover plate, the first support plate does not extend beyond the boundary of the folded portion away from the bent portion, thus not interfering with the installation of other electronic components located on the non-display side. Therefore, the frame on the side containing the bent portion maintains sufficient strength even when narrowed, reducing the risk of display module damage during assembly and application.

[0006] In some embodiments, the display module further includes: a second support plate located on the side of the first support plate near the display panel and abutting against the cover plate; the second support plate and the first support plate are integrally formed; wherein the orthographic projection of the bent portion on the cover plate is offset from the orthographic projection of the second support plate on the cover plate.

[0007] In some embodiments, the display module further includes a buffer layer located between the first frame and the first support plate.

[0008] In some embodiments, the buffer layer includes a plurality of spaced-apart buffer portions, and the orthographic projection of the bent portion on the cover plate is located within the orthographic projection range of the buffer portion on the cover plate.

[0009] In some embodiments, the display module further includes: a second frame and a third support plate, wherein the first frame and the second frame are integral structures, and the first frame and the second frame are arranged circumferentially around the display portion; the third support plate is located on the side of the second frame away from the cover plate and is connected to the second frame; the first support plate and the third support plate are integral structures.

[0010] In some embodiments, the display module further includes: a fourth support plate located on the side of the third support plate near the display panel and abutting against the cover plate; the fourth support plate and the third support plate are an integral structure.

[0011] In some embodiments, the display module further includes a second support plate located on the side of the first support plate near the display panel and abutting against the cover plate; the second support plate and the first support plate are integrally formed; wherein at least one of the first support plate, the second support plate, the third support plate and the fourth support plate has a groove, and the first frame and / or the second frame fills the groove.

[0012] In some embodiments, the display module further includes a spacer, which is stacked with the display portion and located between the display portion and the folding portion.

[0013] On the other hand, a display device is provided. The display device includes a display module and a housing as described in any of the above embodiments. The housing includes a bottom plate and a side plate. The bottom plate is disposed on one side of the side plate and forms an accommodating space around the side plate in a circumferential direction. The display module is disposed within the accommodating space.

[0014] In some embodiments, the side surface of the side plate near the accommodating space abuts against the cover plate; the bottom plate is connected to the first support plate.

[0015] The above-described display device has the same structure and beneficial technical effects as the display panel provided in some of the above embodiments, and will not be described again here. Attached Figure Description

[0029] As used herein, the term “bezel width” refers to the distance between the edge of the portion of the display screen that the display device can show and the side of the housing that matches that edge.

[0030] like Figure 1As shown, embodiments of this disclosure provide a display device 1. A display device refers to a product with image display functionality. Exemplarily, it can be one of the following: a monitor, television, billboard, digital photo frame, drawing screen, laser printer with display functionality, telephone, mobile phone, personal digital assistant (PDA), digital camera, portable camcorder, viewfinder, monitor, navigator, in-vehicle display device, large-area wall, home appliance, information query device (such as business query device for e-government, banks, hospitals, power companies, etc.), and monitor. Also exemplaryly, the display device can be any of the following wearable display devices: an electronic watch (e.g., a phone watch), a smart bracelet, an augmented reality (AR) head-mounted display device, and a virtual reality (VR) head-mounted display device. Next, the display device 1 will be illustrated using an in-vehicle display device as an example.

[0031] Figure 1 This is a structural diagram of a display device provided according to some embodiments of the present disclosure. Figure 2 for Figure 1 The image shows a cross-sectional view of the device at AA'.

[0032] See Figure 1 and Figure 2 The display device 1 includes a display module 10 and a housing 20. The housing 20 includes a base plate 21 and a side plate 22. The side plate 22 is disposed on one side of the base plate 21 and forms an accommodating space 23 around the base plate 21. The display module 10 is disposed in the accommodating space 23 and is configured as a component for displaying images.

[0033] In recent years, with the development of automotive intelligence and connectivity, in-vehicle displays have gradually become an important component of vehicles. Modern automotive in-vehicle displays include central control screens, instrument panel displays, head-up displays (HUDs), and rear-seat entertainment screens. These displays are used to show navigation information, entertainment information, driver assistance information, and vehicle status information, and are gradually becoming the primary means of perception and interaction within the vehicle cabin. Therefore, the design of in-vehicle displays must not only meet users' visual requirements for a good user experience but also possess high reliability and durability to cope with the complex operating conditions of the in-vehicle environment.

[0034] In the design of automotive displays, narrow bezel designs are increasingly favored by the market. Narrow bezels not only enhance the aesthetics of automotive displays and provide users with a better immersive experience, but also increase the effective display area. However, in the automotive environment, displays need to withstand various harsh conditions such as vibration, shock, and temperature changes, which places higher reliability demands on the display module. Narrow bezel design solutions commonly used in consumer electronics, such as the bottom-narrow bezel (BNB) and low-in-plane offset (LIPO) solutions often used in mobile phones, are ill-suited to the harsh conditions of the automotive environment and suffer from insufficient reliability.

[0035] In view of this, the present disclosure provides a display module 10, such as Figure 3 As shown, the display module 10 includes a display panel 11, a cover plate 12, a first frame 131, and a first support plate 141.

[0036] Depending on the display principle, the display panel 11 can be any of the following self-emissive display panels: Organic Light Emitting Diode (OLED) display panel, Quantum Dot Light Emitting Diode (QLED) display panel, and Mini-LED or Micro-LED display panel. Depending on its bendability, the display panel 11 can be a flexible or rigid display panel.

[0037] In some possible implementations, the cover plate 12 is disposed on the display side A of the display panel 11. The cover plate 12 has good light transmittance. For example, the material of the cover plate 12 can be glass. The purpose is to provide a certain degree of protection for the display panel 11 without affecting the display of the display panel 11, so as to avoid the display panel 11 being directly impacted or scratched by the outside world.

[0038] In some possible implementations, the side surface of the housing 20 near the receiving space 23 abuts against the cover plate 12. In some examples, the cover plate 12 is located within the receiving space 23, and the side surface of the cover plate 12 away from the display panel 11 is flush with the side surface of the side plate 22 away from the bottom plate 21. This avoids the cover plate 12 protruding from the receiving space formed by the housing 20, reducing the risk of the edge of the cover plate 12 being damaged by external impacts.

[0039] In some possible implementations, the display panel 11 may be a flexible display panel, including a display portion 111, a folding portion 112, and a bending portion 113 located between the display portion 111 and the folding portion 112, which are interconnected. The display portion 111 has a display side A and a non-display side B, and the folding portion 112 is located on the non-display side B of the display portion 111. In this case, the display module 10 may also include a spacer 16, which is stacked with the display portion 111 and located between the display portion 111 and the folding portion 112. The bending portion 113 bends the folding portion 112 on the side of the spacer 16 away from the display portion 111, that is, the spacer 16 is configured to space the display portion 111 and the folding portion 112 apart.

[0040] like Figure 4 As shown, by using the bending portion 113 to bend the folded portion 112 on the side of the spacer 16 away from the display portion 111, the display portion 111 can be brought closer to the edge of the display module 10, which is beneficial for the narrow bezel of the display device 1. However, with the above arrangement, the relatively fragile bending portion 113 is exposed, and the risk of the bending portion 113 being damaged during the subsequent assembly or use of the display device 1 is greatly increased.

[0041] To address the aforementioned technical issues, such as Figure 3 As shown, the display module 10 of this embodiment includes a first frame 131, which at least covers the bent portion 113 and is connected to the cover plate 12; it also includes a first support plate 141, which is located on the side of the first frame 131 away from the cover plate 12 and is connected to the first frame 131.

[0042] By using a first frame 131 to at least cover the bent portion 113, the fragile bent portion 113 of the display panel 11 can be effectively protected. Simultaneously, a first support plate 141 is provided on the side of the first frame 131 away from the cover plate 12, providing rigid support for the first frame 131 and reducing the risk of deformation and damage to the bent portion 113 under external force. Therefore, the side frame where the bent portion 113 is located can still have sufficient strength even when narrowed, reducing the risk of damage to the display module 10 during assembly and application. As an example, such as... Figure 3 As shown, the first frame 131 is provided to wrap around the bent portion 113 from the side near the spacer 16 and the side away from the spacer 16, respectively. This provides rigid support and fixed protection for the bent portion 113, reducing the risk of damage to the display module 10 from external impacts such as squeezing or collision during subsequent assembly or application.

[0043] In some examples, the spacer 16 may include a heat dissipation assembly disposed between the display portion 111 and the folding portion 112 for dissipating heat from the display portion 111. The heat dissipation assembly may include a thermally conductive material (hereinafter referred to as a thermally conductive material), which is intended to mean a material commonly referred to as a good thermal conductor or known to have heat transfer properties. In one example, the heat dissipation assembly may include a thermally conductive metallic material; for example, it may include metals such as copper (Cu), gold (Au), silver (Ag), aluminum (Al), magnesium (Mg), or nickel (Ni), or an alloy containing at least one of the aforementioned metals. In another example, the heat dissipation assembly may include a thermally conductive carbon-based material; for example, it may include graphite, diamond, carbon fiber, etc. Additionally, the heat dissipation assembly may include a thermally conductive polymer material, such as thermal grease. However, the heat dissipation assembly is not limited to the materials described above and may include combinations of the above materials or other materials not mentioned above.

[0044] In some related technologies, such as Figure 4 As shown, to prevent the edges of the cover plate 12 from warping, a connecting adhesive 30 needs to be provided at the edge of the cover plate 12 to bond the edge of the cover plate 12 to the housing 20. This arrangement requires increasing the thickness of the side plate 22 of the housing 20 to provide space for the connecting adhesive 30; the increased thickness of the side plate 22 of the housing 20 is denoted as L1. Simultaneously, to reduce the risk of damage to the bent portion 113 of the display panel 11 due to collisions with the housing 20 in a vehicle environment caused by vibration or impact, a certain distance L2 needs to be maintained between the bent portion 113 and the housing 20. Furthermore, the display unit 111 includes a display area AA, and the distance between the edge of the bent portion 113 away from the display unit 111 and the edge of the display area AA near the bent portion 113 is denoted as L3. Therefore, in related technologies, the bezel width of the display device is L1 + L2 + L3.

[0045] In some possible embodiments disclosed herein, during the fabrication of the display module 10, the first frame 131 is prepared by compression molding. During this process, the adhesive forming the first frame 131 can be in contact with the cover plate 12 before curing. After curing, the first frame 131 can be directly connected to the cover plate 12. Since the first frame 131 is located at the edge of the display module 10, it is close to the side plate 22 of the housing 20 after assembly. This avoids edge warping of the cover plate 12 without adding a connecting adhesive 30. Thus, the bezel width of the display device 1 is L2+L3. Compared with related technologies, the bezel width of the display device 1 can be reduced; for example, the bezel width of the display device 1 is reduced by L1.

[0046] In some possible implementations, the base plate 21 of the housing 20 is connected to the first support plate 141 of the display module 10. For example, as Figure 5 As shown, the base plate 21 and the first support plate 141 are connected together by structural adhesive 31. By placing the structural adhesive 31 between the base plate 21 and the display module 10, the space required for the circumferential edge of the display module 10 can be further reduced, thus further reducing the bezel width of the display device 1. As an example, such as... Figure 5 As shown, the display module 10 may further include an optically transparent adhesive layer 40, located between the cover plate 12 and the display portion 111 of the display panel 11, for full adhesion between the cover plate 12 and the display panel 11. The optically transparent adhesive 40 is an optically transparent adhesive used to bond transparent optical elements, with a light transmittance exceeding 99%, and possesses high adhesive strength, low shrinkage, anti-whitening properties, and room temperature to medium temperature curing characteristics. The optically transparent adhesive layer 40 can improve color fidelity by matching the refractive index of the display stack, reduce reflectivity to enhance contrast and image clarity, and improve the display effect of the display panel 11.

[0047] As an example, the display module 10 may also include a polarizer 50 located between the optically transparent adhesive layer 40 and the display portion 111 of the display panel 11, for eliminating ambient light reflection, thereby improving the contrast of the light emitted by the display panel 11 and improving the display effect of the display panel 11.

[0048] In some possible implementations, such as Figure 6 As shown, in the orthographic projection onto the cover plate 12, the first support plate 141 does not extend beyond the boundary of the folded portion 112 away from the bending portion 113, and will not affect the setting of other electronic components (e.g., the flip-chip film 17, the circuit board 18) in the display module 10. The circuit board 18 can still be directly attached to the side of the spacer 16 away from the display portion 111, without increasing the thickness of the display module 10.

[0049] Figure 7 This is a structural diagram of a display module according to some other embodiments. Figure 8 for Figure 7 A sectional view at position B-B'.

[0050] In some possible implementations, such as Figure 7 As shown, the display module 10 also includes a second support plate 142. Figure 8 As shown, the second support plate 142 is located on the side of the first support plate 141 closer to the display panel 11, and the second support plate 142 is also located on the side of the first frame 131 away from the display panel 11. The second support plate 142 and the first support plate 141 are an integral structure; continue reading Figure 7 , bending part 113 ( Figure 7(Not shown in the diagram, but can be referenced to the position of the folding part 112) The orthogonal projection of the second support plate 142 on the cover plate 12 is offset from the orthogonal projection of the second support plate 142 on the cover plate 12; the second support plate 142 abuts against the cover plate 12.

[0051] Thus, the overall structure of the first support plate 141 and the second support plate 142, in conjunction with the cover plate 12, can provide stronger support, enabling the first frame 131 to withstand greater compressive force from the housing 20, and reducing the risk of the first frame 131 breaking and damaging the display panel 11 when the display device 1 is subjected to collision or external pressure.

[0052] In some possible implementations, the display module 10 is prepared by injection molding, such as... Figure 9 and Figure 10 As shown, the display panel 11, cover plate 12, and other accessories are placed in the cavity formed by the first mold 2 and the second mold 3. Glue is injected into the cavity, filling the cavity and the space between the bent portion 113 and the spacer 16. After the glue cures, a first glue frame 131 is formed, which fixes and supports the display panel 11.

[0053] Thus, the orthographic projection of the bent portion 113 on the plane of the side surface of the second support plate 142 away from the display panel 11 does not coincide with the orthographic projection of the second support plate 142 on the plane of the side surface of the second support plate 142 away from the display panel 11. That is, the second support plate 142 is not provided in the area corresponding to the bent portion 113, which can avoid the influence of the tolerance of the second support plate 142 during mold closing and obtain a more extreme frame width.

[0054] Here, the area corresponding to the bend 113 does not have a second support plate 142. This avoids the influence of the tolerance of the second support plate 142 during mold closing, resulting in a more extreme border width. The principle is as follows: Figure 11As shown, if a second support plate 142 is also provided in the area corresponding to the bent portion 113, in order to ensure that the portion of the first frame 131 away from the spacer 16 has a minimum width L4 that can provide protection for the bent portion 113, the distance between the surface of the second support plate 142 near the display panel 11 and the bent portion 113 in the area corresponding to the bent portion 113 should be greater than or equal to this minimum width L4. Considering that the second support plate 142 has tolerances and the dimensions of multiple second support plates 142 are different, in order to ensure that the first support plate 141 and the second support plate 142 can be placed into the cavity when the mold is closed, the size of the cavity must be able to accommodate the largest of the multiple second support plates 142. The width of the first frame 131 is determined by the size of the cavity, which will result in the width of the portion of the first frame 131 away from the spacer 16 necessarily being greater than the theoretical minimum width L4. If the second support plate 142 is not provided in the area corresponding to the bending part 113, then there is no need to consider the distance between the second support plate 142 and the bending part 113, and the width of the part of the first frame 131 away from the spacer 16 can be set to the theoretical minimum width L4, that is, a more extreme frame width is obtained.

[0055] As an example, this disclosure provides a method for preparing a display module 10, specifically as follows: First, the display module 10 to be formed into a first adhesive frame 131 is subjected to plasma cleaning to enhance the surface activity of the display module 10 and improve the adhesion between the display module 10 and the adhesive in subsequent processes; high-viscosity, high-thixotropic damming adhesive is precisely applied to the boundary between the bending portion 113 and the cover plate 12 to form a continuous damming adhesive body, which encloses the area to be formed into the first adhesive frame 131. The first support plate 141 and the second support plate 142 (if any) are nested into the second mold 3, and then the display module 10 is placed in it. The first mold 2 is then installed to complete the mold closing. The damming adhesive body is cured by heating, and then thermosetting adhesive is injected into the cavity under low pressure in a vacuum environment, so that the thermosetting adhesive fills the cavity and the space between the bending portion 113 and the spacer 16. The thermosetting adhesive is cured again by heating. After the mold is left to stand and the thermosetting adhesive is confirmed to be completely cured, the first mold 2 and the second mold 3 are separated by a vacuum adsorption process to obtain the display module 10.

[0056] As an example, the material of the first frame 131 includes at least one of epoxy resin, polyimide, polyurethane, phenolic resin or silicone, and this disclosure does not specifically limit this.

[0057] Figure 12 This is a structural diagram of the first support plate 141, the second support plate 142, and the buffer layer 15 according to some embodiments. Figure 13 for Figure 12 Side view of the first support plate 141, the second support plate 142, and the buffer layer 15. Figure 12As shown, multiple second support plates 142 are spaced apart, and the interval between two adjacent second support plates 142 corresponds to a bend 113. Figure 12 (Not shown in the image, but can be referenced to the position of the folding part 112). Figure 13 As shown, the side view structure of the first support plate 141 and the second support plate 142 is generally L-shaped.

[0058] As an example, the first support plate 141 and the second support plate 142 can be an integral structure formed by stamping, or they can be separate structures that are fixedly connected together by welding or other means. This embodiment does not specifically limit the specific structure.

[0059] In some possible implementations, such as Figure 3 As shown, the display module 10 also includes a buffer layer 15, which is located between the first frame 131 and the first support plate 141. The buffer layer 15 can absorb the vibration transmitted by the housing 20, protect the edges of the display module 10, and reduce the risk of damage to the display module 10 caused by vibration of the display device 1 in a vehicle environment.

[0060] In some possible implementations, the buffer layer 15 is a continuous structure, laid entirely between the first adhesive frame 131 and the first support plate 141. This eliminates the need for patterned cutting and alignment of the buffer layer 15, simplifying the manufacturing process and reducing production costs.

[0061] In some possible implementations, such as Figure 12 As shown, the buffer layer 15 includes a plurality of spaced-apart buffer portions 151. The orthographic projection of a bent portion 113 on the cover plate 12 is located within the orthographic projection range of a buffer portion 151 on the cover plate 12. Thus, the portion with the bent portion 113 is provided with a buffer portion 151 to provide a buffering and vibration-absorbing effect for the relatively fragile bent portion 113, reducing the risk of damage to the bent portion 113; the portion without the bent portion 113 is not provided with a buffer portion 151, which can enhance the support between the first support plate 141, the first frame 131 and the spacer 16, and enhance the protective effect of the first frame 131 and the first support plate 141 on the display module 10.

[0062] As an example, the buffer layer 15 can be made of materials with good cushioning properties such as foam or silicone, and this disclosure does not specifically limit this.

[0063] Figure 14 This is a partial structural diagram of the side opposite to the side including the bend 113 in the display module 10 according to some embodiments.

[0064] In some possible implementations, such as Figure 14 As shown, the display module 10 also includes a second frame 132, and a first frame 131 ( Figure 14 (Not shown in the image) and the second frame 132 are an integral structure. The first frame 131 and the second frame 132 are arranged around the circumference of the display part 111. The display module 10 also includes a third support plate 143, which is located on the side of the second frame 132 away from the cover plate 12 and is connected to the second frame 132. The first support plate 141 and the third support plate 143 are an integral structure.

[0065] In some examples, such as Figure 15 As shown, structural adhesive 31 ( Figure 15 (Not shown in the image) It is also located between the third support plate 143 and the base plate 21, which can improve the connection strength between the display module 10 and the housing 20 and improve the reliability of the display device 1. In addition, the orthographic projection of the structural adhesive 31 on the cover plate 12 can be arranged around the orthographic projection of the display panel 11 on the cover plate 12. The structural adhesive 31 forms an annular closed structure, forming a sealed space on the non-display side B of the display panel 11, which can prevent external moisture from entering and affecting electronic components such as the flip-chip film 17 and the circuit board 18 arranged on the non-display side B of the display panel 11, thereby improving the reliability of the display device 1.

[0066] For some possible implementations, please refer to [link / reference]. Figure 14 The display module 10 also includes a fourth support plate 144, which is located on the side of the third support plate 143 near the display panel 11 and on the side of the second frame 132 away from the display panel 11; the fourth support plate 144 and the third support plate 143 are an integral structure, and the fourth support plate 144 abuts against the cover plate 12.

[0067] In some possible implementations, such as Figure 16 As shown, the first support plate 141, the second support plate 142, the third support plate 143 and the fourth support plate 144 are an integral structure.

[0068] The first support plate 141, the second support plate 142, the third support plate 143 and the fourth support plate can be made of metal materials such as aluminum alloy, which can provide strength and shielding while improving the electrical performance of the display module 10, such as electrostatic discharge (ESD). Alternatively, they can be made of materials such as high-strength plastic, with conductive coating applied to the surface of the high-strength plastic to achieve the same shielding effect.

[0069] For some possible implementations, please refer to [link / reference]. Figure 16 At least one of the first support plate 141, the second support plate 142, the third support plate 143 or the fourth support plate 144 has a groove 145, and the first frame 131 and / or the second frame 132 fill the groove 145.

[0070] When the groove 145 is located on the first support plate 141 and / or the second support plate 142, the groove 145 can increase the contact area between the first frame 131 and the first support plate 141 and / or the second support plate 142, and transform the simple planar bonding between the first frame 131 and the first support plate 141 and / or the second support plate 142 into a three-dimensional mechanical interlock, thereby improving the reliability of the connection between the first frame 131 and the first support plate 141 and / or the second support plate 142; when the groove 145 is located on the third support plate 143 and / or the fourth support plate 144, the contact area between the second frame 132 and the third support plate 143 and / or the fourth support plate 144 is increased; and the simple planar bonding between the second frame 132 and the third support plate 143 and / or the fourth support plate 144 is transformed into a three-dimensional mechanical interlock, thereby improving the reliability of the connection between the second frame 132 and the third support plate 143 and / or the fourth support plate 144.
