Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display device. Background Technology

[0002] With the upgrading of consumer demand and the continuous development of technology, display devices such as televisions and monitors have become indispensable products in people's lives.

[0003] As one of the important components in a display device, the back panel is usually designed with a bent "F"-shaped folded edge structure in order to achieve an ultra-thin effect. The display panel and backlight module are installed in the mounting cavity formed by the folding of the back panel.

[0004] However, the backplate of this architecture is currently quite thick in the thickness direction of the display device, making it difficult to achieve an ultra-thin effect when viewed from the side. Utility Model Content

[0005] This application discloses a display device that can achieve a thinner display device effect.

[0006] To achieve the above objectives, in a first aspect, embodiments of this application disclose a display device, comprising:

[0007] A display panel, the display panel including a display area and a non-display area, the non-display area being located on the outer periphery of the display area;

[0008] A backlight module, located on the backlight side of the display panel, the backlight module comprising:

[0009] Optical components, including a light source and a diaphragm assembly;

[0010] Backplate, the backplate comprising:

[0011] A main body plate defining a receiving cavity, wherein the light source is located in the receiving cavity;

[0012] A bending structure extending from the edge of the main body plate, the bending structure comprising, in sequence:

[0013] A first bend is bent and connected to the edge of the main body plate and extends outward from the receiving cavity. The first bend is configured to carry the diaphragm assembly.

[0014] The second bend is bent and connected to the first bend, and extends in a first direction away from the main body plate, wherein the first direction is the thickness direction of the display device;

[0015] The third bend is bent and connected to the second bend and is arranged parallel to the first bend. The third bend is configured to support the display panel.

[0016] The fourth bend is bent and connected to the third bend, and extends in the first direction away from the main body plate.

[0017] The projections of the second bend and the edge of the membrane group onto the display panel both fall within the non-display area.

[0018] The display device provided in this application bends a first bending portion from the edge of the main body plate towards the outside of the receiving cavity, and a second bending portion bends from the first bending portion along the thickness direction of the display device to form a space for mounting a diaphragm assembly, such that the first bending portion carries the diaphragm assembly. A third bending portion bends from the second bending portion towards the outside of the receiving cavity to be parallel to the first bending portion, and a fourth bending portion bends from the third bending portion in a direction away from the main body plate along the thickness direction of the display device to form a space for mounting a display panel, such that the third bending portion carries the display panel, and the projections of the edges of the second bending portion and the diaphragm assembly onto the display panel fall within the non-display area. It can be seen that this application, through multiple bends at the edge of the main body plate, creates a bending structure that roughly presents two mutually staggered L-shaped structures in the thickness direction of the display device, utilizing the space of each L-shape for mounting the display panel and optical components respectively. In other words, in this application, the space corresponding to the film group in the non-display area of ​​the display panel in the related technology is utilized. Through multiple bends, without changing the overall thickness of the back plate, the space used to install the film group is contracted into the cavity, so that the fourth bend extending along the thickness direction of the display device is constructed as the side frame of the display device. This allows the space of the fourth bend in the thickness direction of the display device to be used only to install the display panel, so that the film group does not occupy the thickness space corresponding to the thickness direction of the fourth bend in the thickness direction of the display device. Compared with the method in the related technology where both the film group and the display panel are set in the thickness space corresponding to the fourth bend, the size of the fourth bend in the first direction can be made smaller, thereby reducing the thickness of the frame of the display device and achieving an ultra-thin effect when viewed from the side.

[0019] As an optional implementation, in an embodiment of the first aspect of this application, the bending structure further includes:

[0020] The fifth bend is bent and connected to the fourth bend, and extends toward the main body plate.

[0021] The sixth bend is bent and connected to the fifth bend. The sixth bend is parallel to and attached to the third bend. The third bend carries the sixth bend and is configured to carry the display panel.

[0022] Because the third bend and the sixth bend are fitted together, the third bend can support the sixth bend, and the sixth bend supports the display panel. In other words, the third bend indirectly supports the display panel by supporting the sixth bend. Thus, the sixth bend and the third bend can work together to support the display panel. Compared with a single-layer bending method, the third bend in this application can strengthen the sixth bend, thereby improving the load-bearing capacity of the display panel and making the sixth bend less prone to deformation.

[0023] As an alternative implementation, in an embodiment of the first aspect of this application, the extension length of the sixth bend is greater than the extension length of the third bend, so that the sixth bend is closer to the center of the receiving cavity relative to the third bend.

[0024] It is understandable that when the sixth bend supports the display panel, it is usually positioned at the edge of the display panel. That is, the sixth bend primarily supports the edge of the display panel. If the extension length of the sixth bend is small, the bearing area it can provide for the edge of the display panel is small, which will affect the reliability of the display panel installation. Based on this, this application sets the extension length of the sixth bend to be greater than the extension length of the third bend, so that the sixth bend is closer to the center of the receiving cavity than the third bend. That is, in the direction towards the inside of the receiving cavity, the sixth bend extends beyond the edge where the third bend connects to the main body plate. This configuration provides a larger support area for the display panel without affecting its normal display function. For example, if the display panel is fixed to the back panel by adhesive, the design of the sixth bend extending into the receiving cavity and beyond the third bend provides a larger bonding area for the adhesive tape, resulting in a larger bonding area between the display panel and the sixth bend, thereby improving the reliability of the display panel bonding.

[0025] As an optional implementation, in an embodiment of the first aspect of this application, the sixth bend has a first surface and a second surface disposed opposite to each other along the first direction, the first surface being configured as the bearing surface of the display panel;

[0026] Along the first direction, at least a portion of the diaphragm assembly is located between the second surface and the first bend;

[0027] The second surface is provided with a first adhesive strip facing the diaphragm group, and the first adhesive strip is spaced apart from the diaphragm group along the first direction.

[0028] The sixth bend extends beyond the edge where the third bend connects to the main body plate. While providing a larger load-bearing area for the display panel and improving the reliability of its installation, a first adhesive strip is provided on the second surface of this sixth bend, which extends relative to the third bend. This first adhesive strip can absorb minor impacts or vibrations to protect the diaphragm assembly. Furthermore, since the first adhesive strip is spaced apart from the diaphragm assembly in the thickness direction of the display device, it prevents the diaphragm assembly from being overly tight, thus avoiding direct pressure on the diaphragm assembly and reducing the risk of cracking or damage to the diaphragm.

[0029] Furthermore, by placing the first adhesive strip on the second surface of the sixth bend, it can protect the diaphragm assembly while reducing its impact on the diaphragm assembly compared to placing the first adhesive strip on the diaphragm assembly. This avoids the diaphragm assembly being affected by the aging and delamination of the first adhesive strip under high temperature conditions.

[0030] Optionally, the first adhesive strip can be made of a material with different light transmittance, which can fill the gap between the sixth bend and the film assembly to a certain extent, thereby preventing light leakage at the edges and improving the display uniformity of the display device.

[0031] As an optional implementation, in an embodiment of the first aspect of this application, the distance H1 from the second surface along the first direction to the surface of the first bend toward the sixth bend is 2mm to 5mm.

[0032] The distance from the second surface along the first direction to the surface of the first bend towards the sixth bend is used as the depth for accommodating the film assembly. If this distance is too small, that is, the depth of the space for installing the film assembly in the thickness direction of the display device is too small, on the one hand, if the thickness of the film assembly is sufficient, there is a risk that the film assembly will collide with the sixth bend during the installation process, which requires higher assembly precision and increases the difficulty of sealing the edges, leading to light leakage. On the other hand, if the distance is too small, it will compress the overall thickness of the film assembly, and the structural strength of an excessively thin film assembly is weak, making it easy to deform and more difficult to install.

[0033] If this distance is too large, that is, if the depth of the space used to install the diaphragm assembly in the thickness direction of the display device is too large, on the one hand, if the thickness of the diaphragm assembly is sufficient, the excessive gap between the diaphragm assembly and the sixth bend may lead to light leakage. To avoid this light leakage, a thicker first adhesive strip is required, which will increase material costs. On the other hand, to ensure normal sealing conditions, the overall thickness of the diaphragm assembly needs to be increased, which is not only not conducive to the thinning of the display device, but also increases the reflection path of light in the diaphragm assembly, reduces light efficiency, and is not conducive to brightness display.

[0034] Therefore, by limiting the distance from the second surface along the first direction to the surface of the first bend towards the sixth bend, the depth of the space used to install the diaphragm assembly is within a reasonable range. This allows for better control over the overall thickness of the diaphragm assembly and greater flexibility in the division of the distance between the diaphragm assembly and the sixth bend, which is more conducive to ensuring the assembly process of the diaphragm assembly. Furthermore, it can improve its own structural strength and display performance while ensuring that the first adhesive strip can protect the diaphragm assembly with a relatively thin thickness.

[0035] As an optional implementation, in the embodiment of the first aspect of this application, the distance D between the fifth bending portion and the display panel is 1mm to 3mm.

[0036] If the distance between the fifth bend and the display panel is too small, that is, if the gap between the back panel and the display panel is too small, it will place extremely high demands on the tolerances of the display panel and the back panel, thereby placing higher demands on the manufacturing process and leading to increased manufacturing costs. If the distance between the fifth bend and the display panel is too small, that is, if the gap between the back panel and the display panel is too large, on the one hand, it will lead to insufficient support of the sixth bend for the display panel, affecting the reliability of the display panel installation. On the other hand, since this gap is located on the display side, it is easily visible to the user and affects the aesthetics of the display device.

[0037] Therefore, by limiting the distance between the fifth bend and the display panel to a reasonable range, the aesthetics of the display device can be guaranteed. Furthermore, without changing the extension length of the sixth bend, the sixth bend can provide sufficient support for the display panel, thereby improving the reliability of the display panel installation and reducing the assembly precision requirements between the display panel and the back panel.

[0038] As an optional implementation, in an embodiment of the first aspect of this application, the main body plate has a first side and a second side disposed opposite to each other along a second direction, and a third side and a fourth side disposed opposite to each other along a third direction, wherein the second direction is the width direction of the display device, and the third direction is the height direction of the display device;

[0039] The third side is configured as the top side of the back panel, and the fourth side is configured as the bottom side of the back panel;

[0040] The bending structure is provided on the first side, the second side, and the third side.

[0041] Considering that the fourth side (bottom side) of the back panel usually needs to bear the weight of the whole device, if a bending structure is also used on the fourth side (bottom side), it may not only lead to insufficient rigidity of the overall display device, but also increase the assembly difficulty of the display panel and film assembly.

[0042] Based on this, bending structures are provided on the top, left, and right sides of the back panel to provide sufficient bonding surface for the display panel and ensure its stable fixation.

[0043] Since the main load-bearing direction of the display device is vertically downward, the base or bracket on the ground side is usually directly supported without additional bending and reinforcement. Therefore, while ensuring the overall load-bearing capacity of the display device is reliable, it can reduce the amount of materials used and costs, and reduce bending processes. Furthermore, the three-sided bending structure means that the back panel is not completely enclosed on all sides, which can reduce the assembly difficulty of the display panel film assembly.

[0044] As an optional implementation, in an embodiment of the first aspect of this application, any two adjacent bending structures on the first side, the second side, and the third side are integrally formed, and the connection of the fourth bending portion of the two adjacent bending structures is rounded. The corners of the sixth bending portions of the two adjacent bending structures are respectively provided with notches, and light-shielding members are provided at the notches. The light-shielding members are configured to close the notches.

[0045] The two adjacent bending structures are integrally molded, allowing them to be completely connected. This means that all adjacent bending sections are seamlessly connected, resulting in a smooth back panel with both aesthetic appeal and sufficient structural strength. Furthermore, it eliminates the need for subsequent welding and polishing processes, simplifying the production process.

[0046] The rounded corners not only give the back panel a better appearance but also prevent stress concentration. Furthermore, the rounded corners soften the sharp edges of the back panel, improving the ease of installation of the display device.

[0047] However, the corners of the integrally formed bent structure are prone to cracking due to stress concentration. Therefore, by setting notches at the corners of the two adjacent sixth bends, the internal stress caused by bending during the forming process can be released, reducing the risk of cracking at the corners. On the other hand, it can prevent the two adjacent sixth bends from interfering with each other during bending, and it is also easier to form rounded corners to make room. At the same time, by sealing the notches with light-shielding elements, the sealing performance at the corners can be improved, reducing or preventing light leakage.

[0048] As can be seen, this application sets a notch at the corner of the sixth bend and uses a light-blocking component to seal the notch. While considering the final achievement of a good appearance and the avoidance of light leakage, it also takes into account the factors in the molding process of the back panel, so that the back panel can have a good appearance and effectively avoid light leakage, while also reducing the molding difficulty of the back panel.

[0049] As an optional implementation, in the embodiment of the first aspect of this application, the dimension H2 of the fourth bending portion along the first direction is 3mm to 6mm.

[0050] The fourth bend, as the side frame of the display device, directly affects the thickness of the display device when viewed from the side. If the size of the fourth bend along the first direction is too large, it will be detrimental to the thinning of the display device. If the size of the fourth bend along the first direction is too small, the depth of the thickness space corresponding to the fourth bend in the thickness direction of the display device will be too small. Since this space is used to install the display panel, the thickness of the display panel will be compressed, resulting in a decrease in the deformation resistance of the display panel. During transportation, installation and daily use, it is easy to cause creases or breakage due to external forces.

[0051] Therefore, by limiting the size of the fourth bending portion along the first direction to a reasonable range, the thinning effect of the display device can be effectively achieved, while ensuring the structural strength of the display panel and reducing the risk of creases or even breakage of the display panel during transportation, installation and daily use.

[0052] Secondly, embodiments of this application disclose a display device, including:

[0053] A display panel, the display panel including a display area and a non-display area, the non-display area being located on the outer periphery of the display area;

[0054] A backlight module, located on the backlight side of the display panel, the backlight module comprising:

[0055] Optical components, including a light source and a diaphragm assembly;

[0056] Backplate, the backplate comprising:

[0057] A main body plate defining a receiving cavity, wherein the light source is located in the receiving cavity;

[0058] A bending structure extending from the edge of the main body plate, the bending structure comprising, in sequence:

[0059] A first bend is bent and connected to the edge of the main body plate and extends outward from the receiving cavity. The first bend is configured to carry the diaphragm assembly.

[0060] The second bend is bent and connected to the first bend, and extends in a first direction away from the main body plate, wherein the first direction is the thickness direction of the display device;

[0061] The third bend is bent and connected to the second bend, and is arranged parallel to the first bend.

[0062] The fourth bend is bent and connected to the third bend, and extends in the first direction away from the main body plate.

[0063] The fifth bend is bent and connected to the fourth bend, and extends toward the main body plate.

[0064] The sixth bend is bent and connected to the fifth bend, and the sixth bend is arranged parallel to the third bend. The sixth bend is configured to support the display panel.

[0065] The projections of the second bend and the edge of the membrane group onto the display panel both fall within the non-display area.

[0066] Compared with the prior art, the beneficial effects of this application are:

[0067] The display device provided in this application bends a first bending portion from the edge of the main body plate towards the outside of the receiving cavity, and a second bending portion bends from the first bending portion along the thickness direction of the display device to form a space for mounting a diaphragm assembly, such that the first bending portion carries the diaphragm assembly. A third bending portion bends from the second bending portion towards the outside of the receiving cavity to be parallel to the first bending portion, and a fourth bending portion bends from the third bending portion in a direction away from the main body plate along the thickness direction of the display device to form a space for mounting a display panel, such that the third bending portion carries the display panel, and the projections of the edges of the second bending portion and the diaphragm assembly onto the display panel fall within the non-display area. It can be seen that this application, through multiple bends at the edge of the main body plate, creates a bending structure that roughly presents two mutually staggered L-shaped structures in the thickness direction of the display device, utilizing the space of each L-shape for mounting the display panel and optical components respectively.

[0068] In other words, in this application, the space corresponding to the film group in the non-display area of ​​the display panel in the related technology is utilized. Through multiple bends, without changing the overall thickness of the back plate, the space used to install the film group is contracted into the cavity, so that the fourth bend extending along the thickness direction of the display device is constructed as the side frame of the display device. This allows the space of the fourth bend in the thickness direction of the display device to be used only to install the display panel, so that the film group does not occupy the thickness space corresponding to the thickness direction of the fourth bend in the thickness direction of the display device. Compared with the method in the related technology where both the film group and the display panel are set in the thickness space corresponding to the fourth bend, the size of the fourth bend in the first direction can be made smaller, thereby reducing the thickness of the frame of the display device and achieving an ultra-thin effect when viewed from the side.

Detailed Implementation

[0080] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0081] In this application, the terms "upper," "inner," "outer," "front," and "rear," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0082] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0083] Furthermore, the terms "set up," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0084] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0085] With the upgrading of consumer demand and the continuous development of technology, display devices such as televisions and monitors have become indispensable products in people's lives.

[0086] As one of the important components in a display device, the back panel is usually designed with a bent "F"-shaped folded edge structure in order to achieve an ultra-thin effect. The display panel and backlight module are installed in the mounting cavity formed by the folding of the back panel.

[0087] like Figure 1 As shown, Figure 1The structure of a backplate 1 in the related art is shown. A horizontal first bend 101 is formed at the edge of the backplate 1 by a first bend. A vertical second bend 102 is formed from the first bend 101 by a second bend. A vertical third bend 103 is formed from the second bend 102 by a third bend. A horizontal fourth bend 104 is formed from the third bend 103 by a fourth bend. The first bend 101, portions of the second bend 102, and the fourth bend 104 form a space for mounting a diaphragm assembly 2, and the diaphragm assembly 2 is fixed to the first bend 101. The third bend 103 and the fourth bend 104 form a space for mounting a display panel 3, and the display panel 3 is fixed to the fourth bend 104. The terms "horizontal" and "vertical" refer to [reference needed]. Figure 1 The paper orientation is shown in the figure.

[0088] It is understood that the second bending portion 102 is used as the side frame of the display device. The height of the second bending portion 102 in the vertical direction not only constitutes the mounting cavity of the diaphragm group 2, but also participates in the formation of the mounting cavity of the display panel 3. As a result, the overall thickness of the side frame in the thickness direction of the display device is relatively thick. From the side, it is difficult for the display device to achieve an ultra-thin effect.

[0089] Based on this, the display device provided in this application bends a first bending portion from the edge of the main body plate towards the outside of the receiving cavity, and a second bending portion bends from the first bending portion along the thickness direction of the display device to form a space for mounting a diaphragm assembly, so that the first bending portion carries the diaphragm assembly. A third bending portion bends from the second bending portion towards the outside of the receiving cavity to be parallel to the first bending portion, and a fourth bending portion bends from the third bending portion in a direction away from the main body plate along the thickness direction of the display device to form a space for mounting a display panel, so that the third bending portion carries the display panel, and the projections of the edges of the second bending portion and the diaphragm assembly on the display panel both fall within the non-display area.

[0090] By utilizing the space of the film assembly corresponding to the non-display area of ​​the display panel in related technologies, and through multiple bends, the space used to install the film assembly is contracted into the cavity without changing the overall thickness of the back panel. This allows the fourth bend extending along the thickness direction of the display device to be constructed as the side frame of the display device. The space of the fourth bend in the thickness direction of the display device is used only to house the display panel, so that the film assembly does not occupy the thickness space corresponding to the thickness direction of the fourth bend. Compared with the method in related technologies where both the film assembly and the display panel are located in the thickness space corresponding to the fourth bend, the size of the fourth bend in the first direction can be made smaller, thereby reducing the thickness of the display device's frame and achieving an ultra-thin effect when viewed from the side.

[0091] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0092] Please see Figure 2 , Figure 2 This is an exemplary structural diagram of a display device provided in an embodiment of this application. The display device 100 includes, but is not limited to, electronic display products such as televisions, computer monitors, and liquid crystal display panels 10.

[0093] The display device 100 provided in this application embodiment can be a plate-like structure, such as a rectangular plate-like structure or a square plate-like structure. For ease of understanding, the following explanation and description will take a television set, in which the display device 100 is a rectangular plate-like structure, as an example.

[0094] With the display device 100 in its operating state as a reference, the direction facing the user is defined as the front, and the direction away from the user is defined as the rear. The front-rear direction is the thickness direction of the display device 100, and is defined as the first direction X. The horizontal direction from one side of the display device 100 to the other is the left-right direction, which is also the width direction of the display device 100, and is defined as the second direction Y. The vertical direction from the top to the bottom of the display device 100 is the up-down direction, which is also the height direction of the display device 100, and is defined as the third direction Z.

[0095] Please see Figure 2 and Figure 3 In some embodiments, the display device 100 includes a display panel 10, which includes a display area 11 and a non-display area 12. The display area 11 is used to display images, and the non-display area 12 is located on the outer periphery of the display area 11.

[0096] In some embodiments, the display device 100 includes a backlight module 201 located on the backlight side of the display panel 10.

[0097] Please combine Figures 4 to 6 In some embodiments, the backlight module 201 includes an optical component 20. The optical component 20 includes a light source (not shown) and a diaphragm assembly 21. The diaphragm assembly 21 includes a reflective sheet 211, a diffuser plate 212, and an optical film 213 arranged sequentially from back to front along the thickness direction of the display device 100. The display panel 10 is located in front of the diaphragm assembly 21. Light emitted from the light source is reflected by the reflective sheet 211 and then passes sequentially through the diffuser plate 212 and the optical film 213 before reaching the display panel 10. The liquid crystal molecules in the front panel are deflected by an electric field, reducing the transmittance of light emitted from the optical film 213 into the liquid crystal panel, thereby projecting the light onto filters of different colors to form an image.

[0098] The optical film 213 may include multiple films, which may include a light-enhancing film and multiple prism sheets, or multiple films may include multiple prism sheets.

[0099] In some embodiments, the backlight module 201 may further include a back plate 30. The back plate 30 is the main support structure of the display device 100, and the back plate 30 can be connected to the display panel 10 and the optical components 20 to provide support.

[0100] Optionally, the back plate 30 can be a metal plate, such as an iron plate, an aluminum alloy plate, or a magnesium alloy plate, so that the back plate 30 can have high structural strength when it is thin, and also has good bending performance to facilitate forming.

[0101] In some embodiments, the backplate 30 includes a main plate portion 31, which defines a receiving cavity 301, and the light source is located in the receiving cavity 301.

[0102] It is understood that the receiving cavity 301 has an opening (not shown) oriented along the thickness direction of the display device 100. The display panel 10 is mounted at this opening, and the edge of the display panel 10 is connected to the back plate 30.

[0103] In some embodiments, the back panel 30 includes a bending structure 32 extending from the edge of the main body panel 31. It should be noted that the side surface of the bending structure 32 provided in this application can form the side frame of the display device 100.

[0104] Optionally, the main body plate 31 and the bending structure 32 can be integrally formed. The bending structure 32 is formed from the edge of the main body plate 31 by bending, while the back plate 30 is formed as a whole by stamping, stretching and bending.

[0105] In some embodiments, the display device 100 further includes a rear shell (not shown) connected to the back panel 30. The main body portion 31 of the back panel 30 is covered by the rear shell, and the side of the bent structure 32 is exposed outside the rear shell, forming the side frame of the display device 100.

[0106] Combination Figure 5 and Figure 6 In some embodiments, the bending structure 32 includes a first bending portion 321, which is bent and connected to the edge of the main body plate portion 31 and extends outward from the receiving cavity 301. The first bending portion 321 is configured to carry the diaphragm assembly 21. That is, the first bending portion 321 bends from the edge of the main body plate portion 31 outward from the receiving cavity 301. The first bending portion 321 extends in a direction perpendicular to the first direction X.

[0107] It is understandable that, since the first direction X is the thickness direction of the display device 100, the direction perpendicular to the first direction X can be the width direction of the display device 100 or the height direction of the display device 100.

[0108] In some embodiments, the bending structure 32 includes a second bending portion 322, which is bent and connected to the first bending portion 321 and extends in a direction away from the main body plate portion 31 along a first direction X, wherein the first direction X is the thickness direction of the display device 100. That is, the second bending portion 322 bends from the first bending portion 321 along the thickness direction of the display device 100, and this bending direction is consistent with the orientation of the opening.

[0109] In some embodiments, the bending structure 32 includes a third bending portion 323, which is bent and connected to the second bending portion 322 and is arranged parallel to the first bending portion 321. That is, the third bending portion 323 bends from the edge of the second bending portion 322 toward the outer periphery of the receiving cavity 301. The third bending portion 323 extends in a direction perpendicular to the first direction X.

[0110] In some embodiments, the third bend 323 is configured to carry the display panel 10.

[0111] In some embodiments, the bending structure 32 includes a fourth bending portion 324, which is bent and connected to the third bending portion 323 and extends in a direction away from the main body plate portion 31 along the first direction X. That is, the fourth bending portion 324 bends from the third bending portion 323 along the thickness direction of the display device 100, and the bending direction is consistent with the orientation of the opening.

[0112] As can be seen, in some embodiments, the bending structure 32 may sequentially include a first bending portion 321, a second bending portion 322, a third bending portion 323, and a fourth bending portion 324 formed by bending. The first bending portion 321 and the second bending portion 322 together form a space for mounting the diaphragm assembly 21, which is roughly L-shaped. The third bending portion 323 and the fourth bending portion 324 continue to bend from the edge of the second bending portion 322 to form a space for mounting the display device 100, which is also roughly L-shaped.

[0113] In some embodiments, the projections of the second bend 322 and the edge of the diaphragm group 21 onto the display panel 10 both fall within the non-display area 12. Figure 6 As shown, the edges of the second bend 322 and the diaphragm group 21 are both located below the non-display area 12.

[0114] The edge of the display panel 10 is the non-display area 12. The space of the film group 21, which was originally stacked in the thickness direction of the side frame, is "folded" to the bottom of the non-display area 12 by the bending structure 32. This allows the film group 21 to not extend to the edge of the display panel 10, and thus does not occupy the space of the side frame (the space corresponding to the fourth bending part 324 in the first direction X). As a result, the fourth bending part 324 only needs to provide the thickness space to accommodate the display panel 10 in the thickness direction of the display device 100.

[0115] The display device 100 provided in this application has a first bending portion 321 bent from the edge of the main body plate portion 31 toward the outside of the receiving cavity 301, and a second bending portion 322 bent from the first bending portion 321 along the thickness direction of the display device 100 to form a space for mounting the diaphragm assembly 21, such that the first bending portion 321 carries the diaphragm assembly 21. A third bending portion 323 is bent from the second bending portion 322 toward the outside of the receiving cavity to be parallel to the first bending portion 321, and a fourth bending portion 324 is bent from the third bending portion 323 along the thickness direction of the display device 100 away from the main body plate portion 31 to form a space for mounting the display panel 10, such that the third bending portion 323 carries the display panel 10, and the projections of the edges of the second bending portion 322 and the diaphragm assembly 21 on the display panel 10 both fall within the area of ​​the non-display area 12.

[0116] As can be seen, this application uses multiple bends at the edge of the main body plate 31 to make the bent structure 32 roughly present as two L-shaped structures that are staggered and connected in the thickness direction of the display device 100, and the space of each L-shape is used to install the display panel 10 and the film group 21 respectively. In other words, in this application, the space of the film group 21 corresponding to the non-display area 12 of the display panel 10 in the related technology is utilized. Through multiple bends, without changing the overall thickness of the back plate, the space used to install the film group 21 is contracted into the cavity, so that the fourth bend portion 324 extending along the thickness direction of the display device 100 is constructed as the side frame of the display device 100. The space of the fourth bend portion 324 in the thickness direction of the display device 100 is used only to set the display panel 10, so that the film group 21 does not occupy the thickness space corresponding to the thickness direction of the fourth bend portion 324 in the thickness direction of the display device 100. Compared with the method in the related technology where both the film group 21 and the display panel 10 are set in the thickness space corresponding to the fourth bend portion 324, the size of the fourth bend portion 324 in the first direction X can be made smaller, thereby reducing the thickness of the frame of the display device 100 and achieving an ultra-thin effect of the display device 100 when viewed from the side.

[0117] Continue reading Figure 6From the direction of the first bend 321 toward the display panel 10, the reflective sheet 211, the diffuser plate 212, and the optical film 213 are arranged sequentially, that is, the end of the reflective sheet 211 is fixed on the first bend 321. The other part of the reflective sheet 211 extends into the receiving cavity 301. Correspondingly, the light source is also arranged in the receiving cavity 301. The light source, together with the reflective sheet 211, reflects light to the diffuser plate 212 and the optical film 213 to provide backlight for the display panel 10. The reflective sheet 211 is inclined in the receiving cavity 301. The arrangement of the reflective sheet 211 can adjust the incident and reflection directions of light, thereby improving the light efficiency and guiding the light to scatter in multiple directions, reducing local brightness differences and avoiding "dark corners" or "bright spots" on the screen.

[0118] A receiving cavity 301 is formed in the main plate portion 31 to accommodate the light source. A sub-cavity 302 is formed by bending through the first bending portion 321 and the second bending portion 322. The sub-cavity 302 accommodates part of the diaphragm group 21. On the one hand, the diaphragm group 21 can be placed in a partitioned manner to avoid mutual interference. On the other hand, compared with the possibility that the heat of the lamp strip in the diaphragm group 21 may be concentrated in an integrated cavity, the heat dissipation can be optimized by placing the diaphragm group 21 in a partitioned manner.

[0119] In this embodiment, the support portion for mounting the diaphragm assembly 21 is formed by bending the edge of the main body plate portion 31 twice, without the need for additional structural components for mounting the diaphragm assembly 21, which simplifies the production process and improves production efficiency.

[0120] In some embodiments, the bending structure 32 includes a fifth bending portion 325, which is bent and connected to the fourth bending portion 324 and extends toward the main body plate portion 31. That is, the fifth bending portion 325 bends from the fourth bending portion 324 toward the main body plate portion 31; in other words, the fifth bending portion 325 bends from the fourth bending portion 324 toward the third bending portion 323.

[0121] Optionally, the fifth bend 325 can be bent from the fourth bend 324 toward the third bend 323, bent to be parallel to the fourth bend 324. That is, the fourth bend 324 and the fifth bend 325 roughly form a U-shaped structure. In this example, the fifth bend 325 can be fitted to the fourth bend 324, or the fifth bend 325 can be spaced apart from the fourth bend 324. Alternatively, the fifth bend 325 can be bent from the fourth bend 324 toward the third bend 323, bent to be at an angle to the fourth bend 324. That is, the fourth bend 324 and the fifth bend 325 roughly form a V-shaped structure.

[0122] In some embodiments, the bending structure 32 includes a sixth bending portion 326, which is bent and connected to the fifth bending portion 325. The sixth bending portion 326 is arranged parallel to the third bending portion 323, and the sixth bending portion 326 is configured to carry the display panel 10.

[0123] It is understood that the sixth bend 326 is arranged parallel to the third bend 323, and the sixth bend 326 is configured to support the display panel 10, that is, the sixth bend 326 is located on the side of the third bend 323 opposite to the main body plate 31. In one example, the sixth bend 326 is fitted together with the third bend 323.

[0124] Specifically, in this example, the bending structure 32 includes a sixth bending portion 326, which is bent and connected to the fifth bending portion 325. The sixth bending portion 326 is arranged parallel to and attached to the third bending portion 323, and the third bending portion 323 carries the sixth bending portion 326. The sixth bending portion 326 is configured to carry the display panel 10. That is, the sixth bending portion 326 bends from the fifth bending portion 325 in a direction perpendicular to the first direction X, away from the fourth bending portion 324.

[0125] It is understood that the sixth bend 326 extends and fits onto the third bend 323, wherein the sixth bend 326 is in direct contact with the display panel 10, while the third bend 323 indirectly provides a load-bearing function.

[0126] Because the third bend 323 and the sixth bend 326 are fitted together, the third bend 323 can support the sixth bend 326, and the sixth bend 326 supports the display panel 10. That is, the third bend 323 indirectly supports the display panel 10 by supporting the sixth bend 326. Thus, the sixth bend 326 and the third bend 323 can be used together to support the display panel 10. Compared with the single-layer bending method, the third bend 323 of this application can strengthen the sixth bend 326, thereby improving the load-bearing capacity of the display panel 10 and making the sixth bend 326 less prone to deformation.

[0127] In another example, there is a small gap between the sixth bend 326 and the third bend 323. In this case, the sixth bend 326 serves to support the display panel 10.

[0128] It is worth noting that the fourth bend 324 in the bending structure 32 of this application embodiment is located on the side of the display panel 10, and can form the side bezel of the display device 100. This side bezel does not cover the display panel 10, thereby achieving a full-screen effect.

[0129] In some embodiments, the display panel 10 can be bonded to the sixth bend 326 by the second adhesive strip 40, which can achieve the functions of fixing and cushioning.

[0130] The display panel 10 is fixed by bonding with a second adhesive strip 40, avoiding a rigid connection between the display panel 10 and the back plate 30. The second adhesive strip 40 can be a high-strength adhesive foam strip or a VHB (Very High Bond) double-sided adhesive foam strip, etc., to ensure that the display panel 10 is stably fixed to the back plate 30.

[0131] Preferably, the fifth bend 325 and the fourth bend 324 are parallel and closely fitted, forming a double-layer overlapping structure. This avoids the problem of easy deformation when bending a single layer and improves the deformation resistance of the side frame of the back panel 30. Furthermore, the closely fitted arrangement reduces redundant space and prevents the gap between the display panel 10 and the back panel 30 from increasing due to the tilted arrangement of the fifth bend 325. In other words, the closely fitted structure is more conducive to improving the fit between the display panel 10 and the back panel 30, resulting in a better aesthetic appearance.

[0132] It is understandable that when the sixth bend 326 supports the display panel 10, it is usually supported at the edge of the display panel 10. That is, the sixth bend 326 mainly supports the edge of the display panel 10. If the extension length of the sixth bend 326 is small, the bearing area that the sixth bend 326 can provide for the edge of the display panel 10 will be small, which will affect the reliability of the installation of the display panel 10.

[0133] In some embodiments, the fifth bend 325 has a dimension greater than the thickness of the display panel 10 along the first direction X, so that the display panel 10 is completely housed within the space formed by the fifth bend 325 and the sixth bend 326, and the fourth bend 324 and the fifth bend 325 completely cover the sidewall of the display panel 10, thereby protecting the sidewall of the display panel 10 and preventing the sidewall of the display panel 10 from being damaged by impact.

[0134] In some embodiments, the extension length of the sixth bend 326 is greater than the extension length of the third bend 323, so that the sixth bend 326 is closer to the center of the receiving cavity 301 than the third bend 323.

[0135] It is worth noting that the extension length of the sixth bend 326 is set to be greater than the extension length of the third bend 323, so that the sixth bend 326 is closer to the center of the receiving cavity 301 than the third bend 323. That is, in the direction toward the interior of the receiving cavity 301, the sixth bend 326 extends beyond the edge where the third bend 323 connects to the main body plate 31. In other words, the side of the sixth bend 326 away from the fourth bend 324 protrudes from the side of the third bend 323 away from the fourth bend 324.

[0136] This configuration provides a larger support area for the display panel 10 without affecting its normal display function. For example, if the display panel 10 is fixed to the back plate 30 by adhesive, the arrangement of the sixth bend 326 extending into the receiving cavity 301 and beyond the third bend 323 can provide a larger bonding area for the second adhesive strip 40, resulting in a larger bonding area between the display panel 10 and the sixth bend 326, thereby improving the reliability of the bonding of the display panel 10.

[0137] Combination Figure 6 In some embodiments, the sixth bend 326 has a first surface 326a and a second surface 326b disposed opposite to each other along a first direction X, the first surface 326a being configured as a support surface of the display panel 10.

[0138] In some embodiments, at least a portion of the diaphragm assembly 21 is located between the second surface 326b and the first bend 321 along the first direction X.

[0139] In some embodiments, a first adhesive strip 50 is provided on the second surface 326b and is disposed toward the diaphragm assembly 21. The first adhesive strip 50 is spaced apart from the diaphragm assembly 21 along the first direction X.

[0140] With the sixth bend 326 extending beyond the edge where the third bend 323 connects to the main body plate 31, a larger bearing area can be provided for the display panel 10, improving the reliability of the display panel 10 installation. Furthermore, a first adhesive strip 50 can be provided on the second surface 326b of this portion of the sixth bend 326, which extends relative to the third bend 323. This first adhesive strip 50 can absorb minor impacts or vibrations, protecting the diaphragm assembly 21. In addition, since the first adhesive strip 50 is spaced apart from the diaphragm assembly 21 in the thickness direction of the display device 100, it prevents the diaphragm assembly 21 from being overly tight, thus avoiding direct pressure on the diaphragm assembly 21 and reducing the risk of cracking or damage to the diaphragm.

[0141] Furthermore, by placing the first adhesive strip 50 on the second surface 326b of the sixth bend 326, it can protect the diaphragm assembly 21 and reduce edge light leakage. Compared to placing the first adhesive strip 50 on the diaphragm assembly 21, it can reduce the impact on the diaphragm assembly 21 and avoid the aging and delamination of the first adhesive strip 50 under high temperature conditions, which would affect the diaphragm assembly 21. On the other hand, the first adhesive strip 50 can fill the gap between the sixth bend 326 and the diaphragm assembly 21 to a certain extent, prevent edge light leakage, and improve display uniformity.

[0142] Optionally, the first adhesive strip 50 can be made of different light-transmitting materials, such as cushioning foam strip or silicone strip, which can fill the gap between the sixth bend 326 and the diaphragm group 21 to a certain extent, thereby preventing light leakage at the edges and improving the display uniformity of the display device 100.

[0143] In some embodiments, the distance H1 from the second surface 326b along the first direction X to the surface of the first bend 321 facing the sixth bend 326 is 2mm to 5mm. Optionally, the distance H1 from the second surface 326b along the first direction X to the surface of the first bend 321 facing the sixth bend 326 can be 2mm to 4mm, 3mm to 5mm, or 3mm to 4mm, etc. For example, the distance H1 can be 2mm, 3mm, 4mm, or 5mm.

[0144] The distance from the second surface 326b along the first direction X to the surface of the first bend 321 toward the sixth bend 326 is, in other words, the depth of the sub-cavity 302 used to accommodate the diaphragm assembly 21.

[0145] If the distance H1 is too small, that is, the depth of the space for installing the diaphragm assembly 21 (i.e., the sub-cavity 302) in the thickness direction of the display device 100 is too small, on the one hand, if the thickness of the diaphragm assembly 21 is sufficient, during the installation of the diaphragm assembly 21, there is a risk that the diaphragm assembly 21 will collide with the sixth bend 326, which will require higher assembly precision and increase the difficulty of sealing the edges, leading to easy light leakage; on the other hand, if the distance is too small, it will compress the overall thickness of the diaphragm assembly 21, and the structural strength of the diaphragm assembly 21 that is too thin is weak, it is easy to deform, and it is more difficult to install.

[0146] If the distance H1 is too large, that is, the depth of the space for installing the diaphragm assembly 21 (i.e., the sub-cavity 302) in the thickness direction of the display device 100 is too large, on the one hand, if the thickness of the diaphragm assembly 21 is sufficient, the distance between the diaphragm assembly 21 and the sixth bend 326 will be too large, which may lead to light leakage. In order to avoid light leakage, a thicker first adhesive strip 50 is required, which will increase the material cost. On the other hand, if normal sealing conditions are to be ensured, the overall thickness of the diaphragm assembly 21 needs to be increased, which is not only not conducive to the thinning of the display device 100, but also increases the reflection path of light in the diaphragm assembly 21, reduces the light efficiency, and is not conducive to brightness display.

[0147] Therefore, by limiting the distance from the second surface 326b along the first direction X to the surface of the first bend 321 toward the sixth bend 326, the depth of the sub-cavity 302 for mounting the diaphragm assembly 21 is within a reasonable range. This allows for better control over the overall thickness of the diaphragm assembly 21 and greater flexibility in the spacing between the diaphragm assembly 21 and the sixth bend 326. This is more conducive to ensuring the assembly process of the diaphragm assembly 21 and, while improving its structural strength and display performance, also ensures that the optical components can be protected even with a relatively thin first adhesive strip 50.

[0148] As can be seen from the foregoing, the fourth bend 324 is constructed as the side frame of the display device 100. That is, the fourth bend 324 is exposed. When viewed from the side of the display device 100, the fourth bend 324 visually affects the thickness of the display device 100.

[0149] See Figure 6 , Figure 6 A partial cross-sectional view of a display device provided in an embodiment of this application is shown, wherein H2 is the dimension of the fourth bending portion 324 along the first direction X in this embodiment. In some embodiments, the dimension H2 of the fourth bending portion 324 along the first direction X is 3mm to 6mm. Optionally, the dimension of the fourth bending portion 324 along the first direction X can be 3mm to 5mm, 4mm to 6mm, or 4mm to 5mm, etc., for example, the dimension H2 can be 3mm, 4mm, 5mm, or 6mm, etc. Compared to Figure 1 The thickness h of the second bend 102 in the related art of the display device 100 shown is effectively reduced in the dimension H2 of the fourth bend 324 along the first direction X provided in the embodiment of this application.

[0150] The fourth bend 324 serves as the side frame of the display device 100, directly affecting the thickness of the display device 100 when viewed from the side. If the size of the fourth bend 324 along the first direction X is too large, it will be detrimental to the thinning of the display device 100. If the size of the fourth bend 324 along the first direction X is too small, the depth of the thickness space corresponding to the fourth bend 324 in the thickness direction of the display device 100 will be too small. Since this space is used to install the display panel 10, the thickness of the display panel 10 will be compressed, resulting in a decrease in the deformation resistance of the display panel 10. During transportation, installation, and daily use, it is easy to develop creases or breakage due to external forces.

[0151] Therefore, by limiting the size of the fourth bending portion 324 along the first direction X within a reasonable range, the thinning effect of the display device 100 can be effectively achieved, while ensuring the structural strength of the display panel 10 and reducing the risk of creases or even breakage of the display panel 10 during transportation, installation and daily use.

[0152] In some embodiments, the distance D between the fifth bend 325 and the display panel 10 is 1mm to 3mm. Optionally, the distance between the fifth bend 325 and the display panel 10 can be 1mm to 2mm, 2mm to 3mm, or 1.5mm to 2.5mm, etc. For example, the distance D can be 1mm, 2mm, or 3mm, etc.

[0153] If the distance between the fifth bend 325 and the display panel 10 is too small, that is, if the gap between the back plate 30 and the display panel 10 is too small, it will place extremely high demands on the tolerances of the display panel 10 and the back plate 30, thereby placing higher demands on the manufacturing process and leading to increased manufacturing costs. If the distance between the fifth bend 325 and the display panel 10 is too small, that is, if the gap between the back plate 30 and the display panel 10 is too large, on the one hand, it will cause the sixth bend 326 to provide insufficient support for the display panel 10, affecting the reliability of the installation of the display panel 10. On the other hand, since the gap is located on the display side, it is easily visible to the user and affects the aesthetics of the display device 100.

[0154] Therefore, by limiting the distance between the fifth bend 325 and the display panel 10 to a reasonable range, the aesthetics of the display device 100 can be guaranteed. Furthermore, without changing the extension length of the sixth bend 326, the sixth bend 326 can provide sufficient support for the display panel 10, thereby improving the reliability of the installation of the display panel 10 and reducing the assembly accuracy requirements between the display panel 10 and the back plate 30.

[0155] Please refer to the following: Figure 4 , Figure 7 and Figure 8In some embodiments, the main body plate portion 31 has a first side 31a and a second side 31b disposed opposite each other along a second direction Y, and a third side 31c and a fourth side 31d disposed opposite each other along a third direction Z. Here, the second direction Y is the width direction of the display device 100, and the third direction Z is the height direction of the display device 100.

[0156] In some embodiments, the third side 31c is configured as the top side of the back panel 30, and the fourth side 31d is configured as the bottom side of the back panel 30.

[0157] As can be seen, in the display device 100 provided in this application embodiment, the first side 31a and the second side 31b are the left and right sides of the main body plate 31, respectively, and the third side 31c and the fourth side 31d are the upper and lower sides of the main body plate 31, respectively. That is, the bending structure 32 can be provided along the upper, left and right edges of the main body plate 31, while the bending structure 32 is not provided on the bottom side of the main body plate 31, so as to form an opening 303 for mounting the diaphragm assembly 21 on that side. The opening direction of the opening 303 is consistent with the height direction of the display device 100.

[0158] In this application, the bending structure 32 of the back panel 30 is formed by bending. Considering that the fourth side 31d (bottom side) of the back panel 30 usually needs to bear the weight of the whole machine, if the bending structure 32 is also used on the fourth side 31d (bottom side), it may not only lead to insufficient rigidity of the overall display device 100, but also increase the assembly difficulty of the display panel 10 and the film group 21.

[0159] In some embodiments, the first side 31a, the second side 31b, and the third side 31c are all provided with a bending structure 32. In other words, the fourth side 31d may be provided with a bending structure 32.

[0160] Based on this, bending structures 32 are provided on the top, left and right sides of the back panel 30, which can provide sufficient adhesive surface for the display panel 10 and ensure the stable fixation of the display panel 10.

[0161] Since the main load-bearing direction of the display device 100 is vertically downward, the ground side is usually directly supported by the base or bracket, without the need for additional bending and reinforcement. Therefore, while ensuring the overall load-bearing reliability of the display device 100, the amount of materials used and costs can be reduced, the bending process can be reduced, and the three-sided bending structure 32 makes the back panel 30 not completely closed on all sides, which can reduce the assembly difficulty of the optical components of the display panel 10.

[0162] Optionally, a frame (not shown) can be provided on the fourth side 31d (bottom side) of the back plate 30, and the bottom side of the display panel 10 is connected to the frame. This bending structure 32 allows for a thinner display device 100 while ensuring sufficient load-bearing capacity on the bottom side, thus guaranteeing the overall structural reliability of the display device 100. Of course, in other embodiments, the fourth side 31d of the back plate 30 may not have a frame, and can be supported by a base or bracket.

[0163] In some embodiments, the fourth bend 324, the fifth bend 325, and the sixth bend 326 of any two adjacent bend structures 32 in the first side 31a, the second side 31b, and the third side 31c are connected by welding.

[0164] By connecting two adjacent bent structures 32 by welding after bending, it is possible to splice the bent structures 32 on adjacent sides together, prevent light leakage at the corners, and reduce the requirements for the mold, resulting in lower mold costs.

[0165] In some embodiments, any two adjacent bending structures 32 of the first side 31a, the second side 31b, and the third side 31c are integrally formed, and the connection of the fourth bending portion 324 of the two adjacent bending structures 32 forms a rounded corner 32a.

[0166] The two adjacent bending structures 32 are integrally formed, allowing them to be completely connected. In other words, all adjacent bending sections are integrally connected. This eliminates seams between adjacent bending structures 32, giving the back panel 30 both a good appearance and sufficient structural strength. Furthermore, it eliminates the need for subsequent processes such as welding and grinding, simplifying the production process.

[0167] The rounded corners 32a at the edges and corners not only give the back panel 30 a good appearance, but also prevent stress concentration. In addition, the rounded corners 32a make the edges and corners of the back panel 30 less sharp, thus facilitating the assembly or installation of the display device 100.

[0168] Combination Figure 7 and Figure 8 In some embodiments, any two adjacent bending structures 32 of the first side 31a, the second side 31b, and the third side 31c are integrally formed, and the connection of the fourth bending portion 324 of the two adjacent bending structures 32 forms a rounded corner 32a. The corners of the sixth bending portion 326 of the two adjacent bending structures 32 are respectively provided with notches 326c, and a light-shielding member 60 is provided at the notch 326c. The light-shielding member 60 is configured to close the notch 326c.

[0169] By integrally molding two adjacent bending structures 32, and forming a rounded corner 32a at the connection of the fourth bending portion 324 of the two adjacent bending structures 32, the back panel 30 can have a good appearance. However, the corners of the integrally molded bending structures 32 are prone to cracking due to stress concentration. Therefore, by providing a notch 326c at the corners of the two adjacent sixth bending portions 326, the internal stress caused by bending during the molding process can be released, reducing the risk of cracking at the corners. On the other hand, it can prevent the two adjacent sixth bending portions 326 from interfering with each other during the bending process, and it is also convenient to form a rounded corner 32a at the corners to make room. At the same time, by providing a light-shielding member 60 at the notch 326c for sealing, the sealing performance at the corner can be improved, reducing or preventing light leakage.

[0170] As can be seen, the present application provides a notch 326c at the corner of the sixth bend 326 and uses a light-shielding member 60 to block the notch 326c. While considering the final achievement of a good appearance and the avoidance of light leakage, it also takes into account the factors in the molding process of the back plate 30. This allows the back plate 30 to have a good appearance and effectively avoid light leakage, while also reducing the molding difficulty of the back plate 30.

[0171] Optionally, the aforementioned light-shielding component 60 can be a component such as a silicone block or a rubber block that can be used to shield corners from light.
