Description
Technical Field
[0001] This application relates to the field of display technology, and more particularly to a display device. Background Technology
[0002] The current trend in display device development is towards thinner and lighter designs, resulting in a decreasing distance between the display panel and the backlight module—specifically, the distance between the lower polarizer of the display panel and the optical film assembly of the backlight module. During transportation, display devices may be subjected to impacts or vibrations. Because the distance between the lower polarizer and the optical film assembly is too small, the likelihood of contact and wear between them increases, thus affecting the display performance. Utility Model Content
[0003] This application discloses a display device that, while ensuring the display device is thin and light, avoids contact between the lower polarizer and the optical film, thereby preventing mutual wear between the lower polarizer and the optical film and further ensuring the display effect of the display device.
[0004] To achieve the above objectives, embodiments of this application disclose a display device, comprising:
[0005] The display panel is used to display images and has opposing light-incoming and light-outcoming sides.
[0006] Backlight module, the backlight module comprising:
[0007] Back panel;
[0008] An optical film assembly is disposed on the back plate and faces the display panel;
[0009] The display panel is configured as an arc-shaped structure that protrudes relative to the back plate along the light emission direction, so that the display panel protrudes relative to the optical film group along the light emission direction, such that there is a gap between the optical film group and the display panel along the light emission direction, the gap being used to provide clearance space for the optical film group and the display panel;
[0010] Wherein, the light emission direction is the direction from the light-input side to the light-output side.
[0011] The display device disclosed in this application constructs a display panel as an arc-shaped structure protruding relative to the back panel along the light emission direction. Specifically, the display panel includes liquid crystal glass and a lower polarizer. The lower polarizer is disposed on the light-inlet side and attached to the liquid crystal glass. Along the light emission direction, the lower polarizer protrudes in an arc-shaped structure relative to the optical film assembly of the back panel, thereby allowing a gap between the lower polarizer and the optical film assembly. This gap provides clearance space for the optical film assembly and the display panel. Thus, during transportation, when the display device is bumped or impacted, the clearance space between the lower polarizer and the optical film assembly prevents contact between them, thereby avoiding mutual wear caused by contact and thus preventing problems affecting the display effect of the display device.
[0012] Furthermore, compared to the planar structure of the display panel in the prior art, which results in an excessively thick overall thickness of the display device in order to have sufficient gap between the lower polarizer and the optical film group, the display panel of this application is formed into an arc-shaped structure that protrudes along the light emission direction. This not only achieves sufficient gap between the lower polarizer and the optical film group, but also takes into account the thin and light design of the display device.
[0013] In some embodiments of this application, the optical film assembly has a first surface facing the display panel, and the gap between the first surface and the display panel increases from the edge of the display panel toward the center of the display panel.
[0014] Since the edges of the first surface and the lower polarizer are fixed to the back panel, while the middle of the first surface and the middle of the lower polarizer belong to the display area and cannot be fixed, the middle of the first surface and the middle of the lower polarizer are most affected by vibration during the handling or transportation of the display device. Therefore, by increasing the gap between the first surface and the lower polarizer from the edge of the display panel towards the center, the problem of contact or wear between the middle of the first surface and the middle of the lower polarizer due to vibration during the handling of the display device can be effectively reduced or avoided, thus ensuring the display effect and lifespan of the display device.
[0015] In some embodiments of this application, the surface of the display panel on the light-receiving side is an arc-shaped surface, and the radius of curvature R of the arc-shaped surface satisfies: 150mm≤R≤2100mm.
[0016] By constructing the light-inlet surface of the display panel as an arc shape, and ensuring its radius of curvature satisfies 150mm≤R≤2100mm, the degree of convexity of the arc surface in the light-emitting direction can be controlled by appropriately managing the radius of curvature R. This means, on the one hand, sufficient gaps can be maintained between the optical film assembly and the lower polarizer, preventing contact or wear between them due to vibration during transport, thus ensuring the display effect and lifespan of the display device; on the other hand, the relatively gentle arc shape of the display panel relative to the back panel along the light-emitting direction improves the overall aesthetics of the display device. Furthermore, the gentle arc shape effectively prevents edge distortion or color shift, thereby significantly improving the display effect.
[0017] In some embodiments of this application, the surface of the display panel on the light-receiving side is an arc-shaped surface, and the radius of curvature R of the arc-shaped surface satisfies: R≥0.615a;
[0018] Where 'a' represents the length of the display panel in the width direction.
[0019] As can be seen, by constructing the light-incoming surface of the display panel as an arc-shaped surface with a radius of curvature satisfying R ≥ 0.615a, the degree of convexity of the arc-shaped surface in the light-emitting direction can be controlled by reasonably controlling the radius of curvature R. That is, while ensuring sufficient gap between the optical film assembly and the lower polarizer, it also allows users to have a good viewing angle when viewing the display device at a greater distance, thereby effectively improving the user's viewing experience.
[0020] In other words, when the radius of curvature R of the curved surface is in the above relationship, mutual wear between the optical film assembly and the lower polarizer due to vibration can be avoided during the handling of the display device, ensuring the display effect and service life of the display device. At the same time, constructing the surface of the display panel on the light-incoming side as a curved surface can also expand the viewing angle of the display device, that is, allow users to have a greater viewing distance along the width direction of the display device, and users can see a better display effect, thereby improving the user experience.
[0021] In some embodiments of this application, the surface of the display panel on the light-receiving side is a second surface, the second surface including an edge region and a display area connected to the edge region, the display area being configured to display an image;
[0022] The back plate includes:
[0023] The main body has a receiving cavity for housing the light source;
[0024] The bent portion includes:
[0025] A first bend, which is connected to the edge of the main body portion and extends outward from the receiving cavity, is configured to carry the optical film assembly.
[0026] The second bend is bent and connected to the first bend, and extends away from the main body along the light emission direction;
[0027] A third bend is connected to the second bend and extends toward the interior of the receiving cavity, and the third bend is configured to support the edge region;
[0028] The backlight module also includes an adhesive component disposed on the third bending portion, the edge region being supported on the adhesive component, and the adhesive component being configured to provide a force to the display panel so that the display panel protrudes relative to the optical film group along the light emission direction.
[0029] By setting the first bending part, the second bending part and the third bending part, the back plate can be extended from the light-inlet side of the optical film group to the light-outlet side of the optical film group. The adhesive is used to provide force to the display panel so that the display panel protrudes relative to the optical film group in the light-outlet direction. The adhesive can provide stable support and extrusion force for the protruding shape of the display panel, ensuring that the display panel maintains a stable arc structure.
[0030] In addition, by setting an adhesive to connect the third bend and the edge area, the interior of the cavity can be sealed and the display panel can be supported. Furthermore, the adhesive, located between the third bend and the edge area, can also buffer and dampen the display panel, preventing damage to the display panel due to vibration or collision during the handling or installation of the display device.
[0031] Furthermore, since the third bend is configured to support the edge area, meaning it is structured to fit the edge area, the edge area can be securely attached to the third bend, preventing gaps between them. This improves the load-bearing stability of the back panel on the display panel and also enhances the overall sealing of the display device. Simultaneously, the secure fit between the edge area and the third bend effectively prevents the edge area from loosening or detaching due to external forces during handling or installation of the display device.
[0032] In some embodiments of this application, the optical film assembly has a first surface facing the display panel, the first surface being planar;
[0033] The second surface is an arc-shaped surface, and the edge region is inclined relative to the first surface;
[0034] The third bending portion includes:
[0035] First impression;
[0036] The second surface is disposed opposite to the first surface along the width direction of the display panel;
[0037] The first surface and the second surface are both inclined relative to the first surface, and the inclination angle of the first surface and the second surface relative to the first surface is the same as the inclination angle of the edge region relative to the first surface.
[0038] It is understandable that the first and second surfaces are inclined relative to the first surface, and the inclination angle of the first and second surfaces relative to the first surface is the same as the inclination angle of the edge area relative to the first surface. This ensures that the gap between the first and second surfaces and the edge area remains consistent. By setting an adhesive of the same thickness between the first and second surfaces and the edge area, the edge area can be firmly attached to the first and second surfaces, avoiding gaps between the edge area and the third bend. This helps to improve the load-bearing stability of the back panel on the display panel, while also improving the overall sealing of the display device.
[0039] In some embodiments of this application, the third bending portion includes:
[0040] The third surface is connected to the first surface and the second surface, and the third surface is the upper side surface along the height direction of the back plate. The third surface is an arc-shaped surface that protrudes along the light emission direction.
[0041] As can be seen, the third surface is constructed as an arc shape and protrudes along the light emission direction. This means the structure of the third surface can adapt to the corresponding edge area, allowing the edge area to be firmly attached to the third surface. This improves the load-bearing stability of the back panel on the display panel and the overall sealing of the display device. Furthermore, the secure fit between the edge area and the third surface effectively prevents the edge area from loosening or detaching due to external forces during handling or installation of the display device.
[0042] In some embodiments of this application, the backlight module further includes:
[0043] A frame, wherein the frame is disposed on a first lower side of the back panel along its height direction, and along the light emission direction, the frame is at least partially located between the optical film assembly and the display panel, the frame comprising:
[0044] A first bearing surface is disposed corresponding to the first surface, and the first bearing surface is constructed as a plane and configured to bear the first surface;
[0045] The second bearing surface is provided opposite to the first bearing surface and the second bearing surface along the light emission direction. The second bearing surface is constructed as an arc-shaped surface and is provided corresponding to the second surface to support the second surface.
[0046] By setting the first bearing surface to be a plane and the first surface to also be a plane, and setting the second bearing surface to be an arc-shaped surface and the second surface to also be an arc-shaped surface, the first bearing surface is adapted to the corresponding position of the first surface, and the second bearing surface is adapted to the corresponding position of the second surface. As a result, the contact area between the frame and the lower polarizer and optical film group is larger, which can effectively improve the bearing stability between the frame and the lower polarizer and optical film group, thereby improving the overall structural stability of the display device.
[0047] Furthermore, the first bearing surface and the first surface, as well as the second bearing surface and the second surface, are all bonded together by a sealing element. Since the first bearing surface and the first surface are adapted to each other, and the second bearing surface and the second surface are adapted to each other, the shape of the sealing element is more regular, thereby improving the sealing effect of the display device, preventing external impurities from entering the backlight module and damaging the display device, and improving the service life of the display device.
[0048] In some embodiments of this application, the display panel has a third surface on the light-emitting side, and the third surface is an arc-shaped surface;
[0049] The display device further includes:
[0050] A front housing, the front housing being disposed on a second lower side of the display panel along its height direction, and the front housing extending at least partially to the light-emitting side of the display panel, the front housing comprising:
[0051] A first enclosure surface is provided corresponding to the edge of the third surface, and the first enclosure surface is constructed as an arcuate surface adapted to the third surface to support the third surface.
[0052] This design allows for a tighter fit between the first enclosure surface and the third surface, improving the assembly stability and reliability between the front housing and the display panel. Furthermore, the first enclosure surface and the third surface are connected by a sealing element. Because the first enclosure surface and the third surface are compatible, the shape of the sealing element is more regular, thereby improving the sealing effect of the display device, preventing external impurities from entering the display panel and damaging the display device, and extending the lifespan of the display device.
[0053] In some embodiments of this application, the display panel has a third surface on the light-emitting side, and the third surface is an arc-shaped surface;
[0054] The display device further includes a mid-frame for connecting the back panel and the third surface, the mid-frame comprising:
[0055] A first connecting part is connected to the back plate;
[0056] A second connecting portion, one end of which is connected to the first connecting portion, and the second connecting portion extends in a direction away from the back plate;
[0057] A third connecting portion, the third connecting portion being connected to the other end of the second connecting portion, the third connecting portion comprising:
[0058] Fourth page;
[0059] The fifth surface is disposed opposite to the fourth surface along the width direction of the third surface, and the fourth and fifth surfaces are disposed at an angle relative to the optical film assembly to support the edge of the third surface;
[0060] The sixth surface is the upper side surface along the height direction of the display panel. The sixth surface is an arc-shaped surface and protrudes along the light emission direction.
[0061] As can be seen, by setting the fourth and fifth surfaces at an angle relative to the optical film assembly, and connecting the fourth and fifth surfaces to the two opposite sides of the third surface along its width direction, and the sixth surface to the upper side of the third surface along its height direction, a tight connection between the middle frame and the display panel can be achieved. This prevents the display panel from shaking during handling or installation, thus ensuring the stability of the display panel. Furthermore, since the fourth and fifth surfaces are both angled relative to the third surface, and the sixth surface is curved, this design allows the middle frame to better fit the curved surface of the display panel on the light-emitting side, further improving the overall assembly stability and reliability of the display device. In addition, by connecting the back plate and the display panel with the middle frame, it also serves to fix and protect the display panel and backlight module, preventing damage caused by collisions or compression during handling or installation.
[0062] Compared with the prior art, the beneficial effects of this application are:
[0063] The display device disclosed in this application includes a display panel and a backlight module. The display panel is used to display images, and the backlight module is located on the light-inlet side of the display panel and provides a light source for the display panel. The display panel includes liquid crystal glass and a lower polarizer. The liquid crystal glass has opposing light-inlet and light-outlet sides, and the lower polarizer is disposed on the light-inlet side and attached to the liquid crystal glass. The backlight module includes a back plate and an optical film assembly. The back plate is disposed on the light-inlet side, and the optical film assembly is disposed on the back plate, facing the lower polarizer. The display panel is constructed as an arc-shaped structure convex relative to the back plate along the light-outlet direction, so that the lower polarizer convexes relative to the optical film assembly along the light-outlet direction, thereby creating a gap between the optical film assembly and the lower polarizer. By constructing the display panel as an arc-shaped structure convex relative to the back plate along the light-outlet direction, that is, along the light-outlet direction, the lower polarizer convexes relative to the optical film assembly of the back plate in an arc-shaped structure, thereby enabling a gap between the lower polarizer and the optical film assembly. In this way, when the display device is bumped or struck during transportation, the gap between the lower polarizer and the optical film group can prevent them from coming into contact, thus avoiding mutual wear caused by contact between the lower polarizer and the optical film group, which would affect the display effect of the display device.
[0064] Furthermore, compared to the planar structure of the display panel in the prior art, which results in an excessively thick overall display device in order to have sufficient gap between the lower polarizer and the optical film group, the display panel of this application is formed into an arc structure, which enables a thinner and lighter design of the display device while allowing sufficient gap between the lower polarizer and the optical film group.

[0092] 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.
[0093] In this application, the terms "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," 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.
[0094] 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.
[0095] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" 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.
[0096] 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.
[0097] In the description of this application, it should be noted that the singular forms of "a," "an," and "the" may also include the plural forms, unless the context clearly indicates otherwise. It should also be understood that terms such as "comprising / including" or "having" specify the presence of the stated features, integrals, steps, operations, components, parts, or combinations thereof, but do not preclude the possibility of the presence or addition of one or more other features, integrals, steps, operations, components, parts, or combinations thereof.
[0098] Display devices have become an indispensable household appliance in daily life. Internally, a display device typically includes a display panel and a backlight module. The display panel displays images, while the backlight module supports the display panel and provides a light source. With the continuous advancement of thinner and lighter designs, the internal structure of display devices has also undergone significant changes. Specifically, the distance between the display panel and the backlight module has been continuously reduced, leading to a decrease in the spacing between the lower polarizer and the optical film assembly, in order to meet the requirements of thinner and lighter display devices.
[0099] However, during the actual transportation of display devices, due to the complex and ever-changing road conditions and uncontrollable factors in the logistics process, display devices inevitably suffer from varying degrees of collisions or vibrations. When the distance between the lower polarizer and the optical film assembly is compressed to a certain extent, such external impacts are very likely to cause direct contact between the two. Since both the lower polarizer and the optical film are precision optical components, their surface materials and structural characteristics make them extremely sensitive to friction and wear. Once they come into contact, even slight friction can leave scratches or damage on their surfaces, affecting the normal transmission and deflection of light, ultimately leading to a significant decrease in the display effect of the display device, such as uneven brightness, color distortion, and reduced contrast, seriously affecting the user experience.
[0100] In view of this, the display device disclosed in this application can ensure that there is a gap between the display panel and the backlight module while maintaining the thinness of the display device. This effectively avoids contact between the lower polarizer and the optical film assembly, thereby preventing mutual wear between the lower polarizer and the optical film assembly, thus ensuring the display effect and service life of the display device.
[0101] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.
[0102] Please refer to the following: Figures 1 to 3 , Figure 1 This is one of the structural schematic diagrams of the display device provided in the embodiments of this application. Figure 2 This is an exploded view of the display device provided in an embodiment of this application. Figure 3 This is a front view of a display device provided in an embodiment of this application. This application discloses a display device 100, which can be an organic light-emitting diode (OLED) display device, a light-emitting diode (LED) display device, a liquid crystal display (LCD) device, etc. This embodiment does not further limit the type of display device 100.
[0103] The display device 100 has an upper side and a lower side along the height direction Z, a left side and a right side along the width direction Y, and a front side and a rear side along the thickness direction. The side of the display device 100 facing the user is the front side, and the side of the display device 100 away from the user is the rear side. When the display device 100 is in a standing (e.g., placed on a table via a base) or wall-mounted (e.g., hung on a wall via a wall mount), the absolute height of the upper side of the display device 100 is greater than the absolute height of the lower side.
[0104] It can be understood that the extension direction between the top and bottom sides is the height direction Z of the display device 100, the extension direction between the left and right sides is the width direction Y of the display device 100, and the extension direction between the front and rear sides is the thickness direction (i.e., the light emission direction X of the display device 100). It is known that among the width direction Y, the light emission direction X, and the height direction Z, each pair is perpendicular. That is to say, the width direction Y is perpendicular to the light emission direction X, the width direction Y is perpendicular to the height direction Z, and the light emission direction X is perpendicular to the height direction Z.
[0105] In some embodiments, the display device 100 includes a frame (not shown), which may be fixedly connected to the four edges of the back panel or detachably connected to the four edges of the back panel. This application embodiment does not limit this.
[0106] In some embodiments, the display device 100 includes a display panel 10, which includes a liquid crystal glass 11 for displaying text and image information. The liquid crystal glass 11 has opposing light-input sides 11a and light-output sides 11b, with the light output direction X being the direction from the light-input side 11a to the light-output side 11b; that is, the light-input side 11a and the light-output side 11b are arranged opposite each other along the light output direction X. It can be understood that the light-input side 11a and the light-output side 11b are opposite sides of the liquid crystal glass 11 along the thickness direction of the display device 100; that is, the light output direction X is parallel to the thickness direction of the display device 100.
[0107] In some embodiments, the liquid crystal glass 11 has a display area 101b and an edge area 101a surrounding the display area 101b. The display area 101b is used to display images, and the edge area 101a is usually a non-display area, mainly used to connect the liquid crystal glass 11 to other components (e.g., the back panel 21).
[0108] In some embodiments, the display panel 10 includes an upper polarizer 12, which is disposed on the light-emitting side 11b and attached to the liquid crystal glass 11. The direction of the polarized light passing through the upper polarizer 12 can be controlled to achieve functions such as image display, brightness adjustment, and contrast adjustment.
[0109] In some embodiments, the display panel 10 further includes a lower polarizer 13, which is disposed on the light-inlet side 11a and attached to the liquid crystal glass 11. The lower polarizer 13 can convert unpolarized light into light with a single polarization direction.
[0110] In some embodiments, the display device 100 further includes a backlight module 20, which provides a light source for the display panel 10.
[0111] In some embodiments, the backlight module 20 includes a back plate 21 disposed on the light-inlet side 11a. The back plate 21 is the main support component of the display device 100. The back plate 21 has a receiving cavity 211a. The back plate is used to install a light source 22, an optical film group 23, a reflective sheet 24, a diffuser sheet 251, and a diffuser bracket 252.
[0112] In some embodiments, the backlight module 20 includes a light source 22 for emitting light. The light source 22 is mounted in a receiving cavity 211a of the backplate 21 to emit light toward the optical film assembly 23. Exemplarily, the light source 22 can be a light bar, light strip, light-emitting diode (LED) chip, etc. Optionally, the light source 22 can be a direct-lit light source or a side-lit light source. When the light source 22 is a side-lit light source, the backlight module 20 also includes a light guide plate (not shown) for diffusing the line light source into a surface light source.
[0113] In some embodiments, the backlight module 20 further includes an optical film assembly 23, which is disposed on the backplate 21, located between the lower polarizer 13 and the light source 22, and facing the lower polarizer 13. The optical film assembly 23 is used to improve the uniformity of incident light to enhance the brightness of the incident light. The optical film assembly 23 may include a brightness enhancement film, a diffusion film, and a reflective film, etc.
[0114] In some embodiments, the backlight module 20 further includes a reflector 24, which is disposed on the back plate 21 and located on the side of the light source 22 away from the back plate 21, for reflecting the light emitted by the light source 22 toward the light-emitting side 11b, thereby improving the energy utilization rate of the light source 22.
[0115] In some embodiments, the backlight module 20 further includes a diffuser 251 and a diffuser support 252. The diffuser 251 is disposed on the light-inlet side 11a of the optical film group 23 and is located between the optical film group 23 and the light source 22. The diffuser support 252 is disposed on the back plate 21 to support the diffuser 251. The diffuser 251 is used to diffuse the incident light, thereby fully mixing the light emitted from the light source 22, so that the light emitted after passing through the diffuser 251 is more uniform.
[0116] In some embodiments, the display panel 10 is configured as an arcuate structure that protrudes relative to the back plate 21 along the light emission direction X, such that the lower polarizer 13 protrudes relative to the optical film group 23 along the light emission direction X, such that there is a gap W between the optical film group 23 and the lower polarizer 13 along the light emission direction X, the gap W being used to provide clearance space for the optical film group 23 and the display panel 10.
[0117] The display device 100 disclosed in this application constructs the display panel 10 as an arc-shaped structure protruding relative to the back plate 21 along the light emission direction X. That is, along the light emission direction X, the lower polarizer 13 protrudes in an arc-shaped structure relative to the optical film group 23 of the back plate 21, thereby allowing a gap W between the lower polarizer 13 and the optical film group 23. In this way, during transportation, when the display device 100 is bumped or impacted, a clearance space is formed by the gap W between the lower polarizer 13 and the optical film group 23. The existence of the clearance space can prevent the lower polarizer 13 and the optical film group 23 from contacting each other, thereby avoiding mutual wear caused by contact between the lower polarizer 13 and the optical film group 23, which would affect the display effect of the display device 100.
[0118] Furthermore, compared to the planar structure of the display panel 10 in the prior art, which results in an excessively large overall thickness of the display device 100 in order to have sufficient gap between the lower polarizer 13 and the optical film group 23, the display panel 10 of this application is formed as an arc-shaped structure protruding along the light emission direction X. This not only ensures sufficient gap between the lower polarizer 13 and the optical film group 23, but also achieves a thinner and lighter design for the display device 100.
[0119] Please see Figure 4 , Figure 4 This is a top view of the display device provided in an embodiment of this application, wherein the protrusion of the display panel 10 is shown in order to facilitate the demonstration. Figure 4 A dashed line S parallel to the width direction Y is shown, from... Figure 4 As can be seen, the display panel 10 has a convex arc-shaped structure, which, compared to a flat surface, can better maintain the gap W between the optical film group 23 and the lower polarizer 13. In some embodiments of this application, the optical film group 23 has a first surface 231 facing the lower polarizer 13, and the gap W between the first surface 231 and the lower polarizer 13 increases from the edge of the display panel 10 towards the center of the display panel 10.
[0120] As can be seen, since the edges of the first surface 231 and the lower polarizer 13 are fixed to the back plate 21, while the middle parts of the first surface 231 and the lower polarizer 13 belong to the display area 101b and cannot be fixed, the middle parts of the first surface 231 and the lower polarizer 13 are most affected by vibration during the handling or transportation of the display device 100. Therefore, by setting the gap W between the first surface 231 and the lower polarizer 13 to increase from the edge of the display panel 10 towards the center, the problem of easy contact or wear between the middle parts of the first surface 231 and the lower polarizer 13 due to vibration during the handling of the display device 100 can be effectively reduced or avoided, thus ensuring the display effect and service life of the display device 100.
[0121] In some embodiments, the surface of the display panel 10 on the light-receiving side 11a is an arc-shaped surface, and the radius of curvature R of the arc-shaped surface satisfies: 150mm≤R≤2100mm. Optionally, this relationship may further satisfy 150mm≤R≤400mm, 400mm≤R≤750mm, 750mm≤R≤1000mm, 1000mm≤R≤1250mm, 1250mm≤R≤1500mm, 1500mm≤R≤1750mm, 1750mm≤R≤2000mm, and 2000mm≤R≤2100mm. For example, R can be 150mm, 200mm, 250mm, 300mm, 450mm, 500mm, 550mm, 600mm, 650mm, 700mm, 750mm, 800mm, 850mm, 900mm, 950mm, 1000mm, 1050mm, 1100mm, 1150mm, 1200mm, 1250mm, 1300mm, 1350mm, 1400mm, 1450mm, 1500mm, 1550mm, 1600mm, 1650mm, 1700mm, 1750mm, 1800mm, 1850mm, 1900mm, 1950mm, 2000mm, 2050mm, 2100mm, etc., and the embodiments of this application do not limit it.
[0122] Understandably, when the radius of curvature R of the curved surface is less than 150mm, the curved structure of the display panel 10 will be too curved, which may cause excessive stress to be generated in the display panel 10 during manufacturing or installation, thereby affecting the flatness and display effect of the liquid crystal glass 11. When the radius of curvature R of the curved surface is greater than 2100mm, although the stress of the display panel 10 can be reduced, the effect of the curved structure will become less obvious, and the gap W between the lower polarizer 13 and the optical film group 23 will be reduced, thereby reducing the protective effect against mutual wear between the lower polarizer 13 and the optical film group 23.
[0123] By constructing the surface of the display panel 10 on the light-inlet side 11a as an arc-shaped surface, and ensuring that its radius of curvature satisfies 150mm≤R≤2100mm, the degree of protrusion of the arc-shaped surface in the light-emitting direction X can be controlled by reasonably controlling the radius of curvature R of the arc-shaped surface. That is, on the one hand, sufficient gap can be achieved between the optical film group 23 and the lower polarizer 13, avoiding mutual contact or wear between the optical film group 23 and the lower polarizer 13 due to vibration during the handling of the display device 100, thereby ensuring the display effect and service life of the display device 100; on the other hand, the arc-shaped structure of the display panel 10 protruding relative to the back plate 21 in the light-emitting direction X is relatively gentle, which can improve the overall aesthetics of the display device 100. At the same time, the relatively gentle arc-shaped structure of the display panel 10 can also effectively avoid edge image distortion or color change of the display device 100, thereby effectively improving the display effect of the display device 100.
[0124] Please see Figure 5 , Figure 5 This is a diagram illustrating the relative positional relationship between the user and the display device, where... Figure 5 The solid black dot indicates the user's location. In some embodiments, the surface of the display panel 10 on the light-receiving side 11a is an arc-shaped surface. Specifically, the radius of curvature of the arc-shaped surface satisfies:
[0125]
[0126] Where a is the length of the display panel 10 in the width direction Y, b is the farthest distance along the light emission direction X when the user views the display device 100, and c is the farthest distance along the width direction Y when the user views the display device 100. Define b = 2.75a and c = a, then we can conclude that R ≥ 0.615a.
[0127] By combining the length *a* of the display panel 10 in the width direction Y, the farthest distance *b* along the light emission direction when the user views the display device 100, and the farthest distance *c* along the width direction X when the user views the display device 100, the radius of curvature *R* of the surface of the display panel 10 on the light-inlet side 11a is obtained. It can be seen that by constructing the surface of the display panel 10 on the light-inlet side 11a as an arc-shaped surface, and ensuring that its radius of curvature *R* ≥ 0.615a, the degree of convexity of the arc-shaped surface in the light emission direction X can be controlled by reasonably controlling the radius of curvature *R*. That is, while ensuring sufficient gap *W* between the optical film group 23 and the lower polarizer 13, a good viewing angle can also be provided when the user views the display device from a greater distance, thereby effectively improving the user's viewing experience.
[0128] In other words, when the radius of curvature R of the curved surface is in the above-mentioned relationship, mutual wear between the optical film group 23 and the lower polarizer 13 due to vibration can be avoided during the handling of the display device 100, thus ensuring the display effect and service life of the display device 100. At the same time, constructing the surface of the display panel 10 on the light-inlet side 11a as a curved surface can also expand the viewing angle of the display device 100, that is, it allows the user to have a greater viewing distance along the width direction Y of the display device 100, and the user can observe a better display effect, thereby improving the user experience.
[0129] Please refer to the following: Figures 6 to 7 , Figure 6 for Figure 3 Sectional view of AA, Figure 7 This is a schematic diagram of the structure of the back panel provided in an embodiment of this application. In some embodiments, the surface of the display panel 10 on the light-receiving side 11a is a second surface 131, and the second surface 131 includes an edge region 101a (see...). Figure 3 ) and the display area 101b connected to the edge area 101a (see Figure 3 The display area 101b is configured to display an image.
[0130] In some embodiments, the back plate 21 includes a main body portion 211 and a bent portion 212. The main body portion 211 has a receiving cavity 211a for receiving the light source 22.
[0131] It is understood that the main body 211 can be a square, rectangular, circular or polygonal shell structure, and the embodiments of this application do not limit this.
[0132] In some embodiments, the bent portion 212 includes a first bent portion 2121, a second bent portion 2122, and a third bent portion 2123. The first bent portion 2121 is connected to the edge of the main body portion 211 and extends outward toward the receiving cavity 211a. The first bent portion 2121 is configured to carry the optical film assembly 23. The second bent portion 2122 is bent and connected to the first bent portion 2121 and extends away from the main body portion 211 along the light emission direction X. The third bent portion 2123 is bent and connected to the second bent portion 2122 and extends inward toward the receiving cavity 211a. The third bent portion 2123 is configured to carry the edge region 101a. By providing the first bending portion 2121, the second bending portion 2122, and the third bending portion 2123, the back plate 21 can extend from the light-inlet side of the optical film group 23 to the light-outlet side of the optical film group 23 to support the display panel 10 and provide support for the installation of the display panel 10.
[0133] It is understandable that the back plate 21 is a sheet metal part, and the first bent portion 2121, the second bent portion 2122 and the third bent portion 2123 can be formed by bending the sheet metal part.
[0134] Optionally, the backlight module 20 also includes an adhesive member 27, which is disposed on the third bend 2123, and the edge region 101a is supported on the adhesive member 27. By providing the adhesive member 27 to connect the third bend 2123 and the edge region 101a, the interior of the receiving cavity 211a can be sealed and the display panel 10 can be supported. Furthermore, the adhesive member 27, disposed between the third bend and the edge region, can buffer and dampen the display panel 10, preventing damage to the display panel 10 due to vibration or collision during the handling or installation of the display device 100.
[0135] Specifically, by providing the first bending portion 2121, the second bending portion 2122, and the third bending portion 2123, the back plate 21 can extend from the light-inlet side of the optical film group 23 to the light-outlet side of the optical film group 23. The adhesive 27 is used to provide force to the display panel 10 so that the display panel 10 protrudes relative to the optical film group 23 along the light-outlet direction X. The adhesive 27 can provide stable support and compression force for the protruding shape of the display panel 10, ensuring that the display panel 10 maintains a stable arc structure.
[0136] For example, the adhesive 27 can be made of elastic materials such as foam or silicone to improve the cushioning effect. Furthermore, the shape and size of the adhesive 27 can be customized according to the shape and size of the display panel 10 and the edge area 101a to ensure that the edge area 101a can be stably supported on the adhesive 27.
[0137] Please refer to the following: Figures 8A to 10 , Figure 8A for Figure 3 Sectional view of BB, Figure 8B for Figure 8A A magnified view of a section at point C. Figure 9 This is a schematic diagram of the structure of the adhesive frame provided in the embodiments of this application. Figure 10 This is a schematic diagram of the front housing provided in an embodiment of this application. In some embodiments, the optical film group 23 faces the first surface 231 of the downward polarizer 13. The first surface 231 is planar, and the surface of the display panel 10 on the light-inlet side 11a is the second surface 131, which is an arc-shaped surface. The edge region 101a is inclined relative to the first surface 231, and the third bending portion 2123 is inclined relative to the first surface 231. The inclination angle of the third bending portion 2123 relative to the first surface 231 is the same as the inclination angle of the edge region 101a relative to the first surface 231.
[0138] Since the third bend 2123 is configured to support the edge region 101a, the tilt angle of the third bend 2123 relative to the first surface 231 is set to be consistent with the tilt angle of the edge region 101a relative to the first surface 231. In other words, the third bend 2123 is constructed to fit the edge region 101a, allowing the edge region 101a to be securely attached to the third bend 2123, preventing gaps between them. This improves the load-bearing stability of the backplate 21 on the display panel 10 and enhances the overall sealing of the display device 100. Furthermore, the secure fit between the edge region 101a and the third bend 2123 effectively prevents the edge region 101a from loosening or detaching due to external forces during handling or installation of the display device 100.
[0139] The inclination angle of the third bend 2123 relative to the first surface 231 is the same as the inclination angle of the edge region 101a relative to the first surface 231. This means that the inclination angles formed by the third bend and the edge region relative to the same reference plane (e.g., the first surface 231) are equal or approximately equal. It can be understood that the edge region 101a is inclined relative to the first surface 231, and the third bend 2123 is also inclined relative to the first surface 231, and the inclination angles of both relative to the first surface 231 are the same.
[0140] In other words, during the actual manufacturing process, errors may occur due to various factors, resulting in a deviation between the actual tilt angle of the component and the tilt angle required by the design. These factors include, but are not limited to, the precision limitations of the processing equipment, the differences in the characteristics of the raw materials, and the varying levels of skill among the operators. However, even if the design requires the edge region 101a and the third bend 2123 to have the same tilt angle relative to the first surface 231, errors in the manufacturing process may cause the actual tilt angle of the edge region 101a relative to the first surface 231 to be slightly different from the actual tilt angle of the third bend 2123 relative to the first surface 231, resulting in a certain degree of deviation. However, this is still within the scope of the consistent tilt angle covered by this application.
[0141] Optionally, the third bending portion 2123 includes a first surface 2123a and a second surface 2123b, which are disposed opposite to the first surface 2123a along the width direction Y of the display panel 10. Both the first surface 2123a and the second surface 2123b are inclined relative to the first surface 231, and the inclination angle of the first surface 2123a and the second surface 2123b relative to the first surface 231 is the same as the inclination angle of the edge region 101a relative to the first surface 231.
[0142] It is understood that the first surface 2123a and the second surface 2123b are inclined relative to the first surface 231. The inclination angle of the first surface 2123a and the second surface 2123b relative to the first surface 231 is consistent with the inclination angle of the edge area 101a relative to the first surface 231. This ensures that the gap between the first surface 2123a and the second surface 2123b and the edge area 101a remains consistent. In other words, by setting an adhesive 27 of the same thickness between the first surface 2123a and the second surface 2123b and the edge area 101a, the edge area can be firmly attached to the first surface 2123a and the second surface 2123b, avoiding gaps between the edge area 101a and the third bend 2123. This is beneficial to improving the load-bearing stability of the back plate 21 on the display panel 10, while also improving the overall sealing of the display device 100.
[0143] Optionally, the third bending portion 2123 includes a third surface 2123c, which is connected to the first surface 2123a and the second surface 2123b. The third surface 2123c is the upper side surface along the height direction Z of the back plate 21, and the third surface 2123c is an arc-shaped surface. The third surface 2123c protrudes along the light emission direction X.
[0144] As can be seen, the third surface 2123c is constructed as an arc-shaped surface and protrudes along the light-emitting direction X. That is, the structure of the third surface 2123c can be adapted to the corresponding edge area 101a, so that the edge area 101a can be firmly attached to the third surface 2123c, thereby improving the load-bearing stability of the back plate 21 on the display panel 10 and the overall sealing of the display device 100. In addition, the firm attachment between the edge area 101a and the third surface 2123c can also effectively prevent the edge area 101a from loosening or falling off due to external forces during the handling or installation of the display device 100.
[0145] See again Figure 9 In some embodiments, the backlight module 20 further includes a frame 26 disposed on the first lower side 21a of the back plate 21 along its height direction Z, for supporting the display panel 10. And along the light emission direction X, the frame 26 is at least partially located between the optical film group 23 and the lower polarizer 13.
[0146] Optionally, the frame 26 includes a first bearing surface 261 and a second bearing surface 262. The first bearing surface 261 is disposed corresponding to the first surface 231 and is constructed as a plane. The first bearing surface 261 is configured to bear the first surface 231. The first bearing surface 261 and the second bearing surface 262 are disposed opposite to each other along the light emission direction X. The second bearing surface 262 is constructed as an arc-shaped surface and is disposed corresponding to the second surface 131 to bear the second surface 131.
[0147] By setting the first bearing surface 261 as a plane and the first surface 231 as a plane, and setting the second bearing surface 262 as an arc-shaped surface and the second surface 131 as an arc-shaped surface, the first bearing surface 261 is adapted to the corresponding position of the first surface 231, and the second bearing surface 262 is adapted to the corresponding position of the second surface 131. As a result, the contact area between the frame 26 and the lower polarizer 13 and the optical film group 23 is larger, which can effectively improve the bearing stability between the frame 26 and the lower polarizer 13 and the optical film group 23, thereby improving the overall structural stability of the display device 100.
[0148] Furthermore, the first bearing surface 261 and the first surface 231, and the second bearing surface 262 and the second surface 131 are both bonded together by the sealing element 50. Since the first bearing surface 261 and the first surface 231 are adapted to each other, and the second bearing surface 262 and the second surface 131 are adapted to each other, the shape of the sealing element 50 becomes more regular, thereby improving the sealing effect of the display device 100, preventing external impurities from entering the backlight module 20 and damaging the display device 100, and extending the service life of the display device 100. Optionally, the sealing element 50 can be made of adhesive materials such as double-sided tape or foam adhesive to facilitate the sealed connection between the first bearing surface 261 and the first surface 231, and between the second bearing surface 262 and the second surface 131.
[0149] In some embodiments, the liquid crystal glass 11 has a third surface 111 on the light-emitting side 11b, and the third surface 111 is an arc-shaped surface. Since the light-emitting side 11b of the liquid crystal glass 11 has an arc-shaped surface that protrudes along the light-emitting direction X, this design can effectively expand the viewing angle of the display device 100, that is, enable the user to have a greater viewing distance along the width direction Y of the display device 100, and the user can see a good display effect, thereby improving the user experience.
[0150] See again Figure 10 In some embodiments, the display device 100 further includes a front housing 30, which is disposed on the second lower side 11c of the liquid crystal glass 11 along its height direction Z, and the front housing 30 extends at least partially to the light-emitting side 11b of the liquid crystal glass 11 for direct contact with the user and to protect the liquid crystal glass 11.
[0151] Optionally, the front housing 30 includes a first retaining surface 31, which is disposed corresponding to the edge of the third surface 111. The first retaining surface 31 is constructed as an arc-shaped surface adapted to the third surface 111 to support the third surface 111. This design allows the first retaining surface 31 to fit more tightly with the third surface 111, improving the assembly stability and reliability between the front housing 30 and the liquid crystal glass 11. Furthermore, the first retaining surface 31 and the third surface 111 are connected by a sealing member 50. Because the first retaining surface 31 is adapted to the third surface 111, the shape of the sealing member 50 is more regular, thereby improving the sealing effect of the display device 100, preventing external impurities from entering the display panel 10 and damaging the display device 100, and extending the service life of the display device 100.
[0152] Optionally, the front housing 30 also includes a second enclosure surface 32, which is disposed opposite to the first enclosure surface 31 along the light emission direction X. The second enclosure surface 32 is an arc-shaped surface and is configured to block the side of the liquid crystal glass 11 to improve the overall aesthetics of the display device 100.
[0153] Please refer to the following: Figures 11A to 12 , Figure 11A This is one of the cross-sectional views of the display device provided in the embodiments of this application. Figure 11B for Figure 11A A magnified view of a section at point D. Figure 11C for Figure 11A A magnified view of a section at point E in the middle. Figure 12 This is a second cross-sectional view of a display device provided in an embodiment of this application. In some embodiments, the display device 100 may further include a middle frame 40, which is used to connect the back panel 21 and the liquid crystal glass 11, and the middle frame 40 is disposed around the outer periphery of the liquid crystal glass 11.
[0154] In some embodiments, the middle frame 40 includes a first connecting portion 41, a second connecting portion 42, and a third connecting portion 43. The first connecting portion 41 is connected to the back plate 21. One end of the second connecting portion 42 is connected to the first connecting portion 41 and extends in a direction away from the back plate 21. The third connecting portion 43 is connected to the other end of the second connecting portion 42. The third connecting portion 43 is disposed around the outer periphery of the liquid crystal glass 11 for connection with the liquid crystal glass 11.
[0155] It is understood that the first connecting part 41, the second connecting part 42 and the third connecting part 43 can be plate-shaped, block-shaped or strip-shaped structures, and the embodiments of this application do not limit this.
[0156] Optionally, the third connecting portion 43 includes a fourth surface 431, a fifth surface 432, and a sixth surface 433. The fifth surface 432 and the fourth surface 431 are disposed opposite each other along the width direction Y of the third surface 111. The fifth surface 432 and the fourth surface 431 are inclined relative to the optical film assembly 23 to support the edge of the third surface 111. The sixth surface 433 is the upper side surface along the height direction Z of the display panel 10. That is, the fourth surface 431, the fifth surface 432, and the sixth surface 433 surround and connect to the side of the third surface 111. The fourth surface 431 and the fifth surface 432 are both inclined relative to the third surface 111. The sixth surface 433 is an arc-shaped surface and protrudes along the light emission direction X.
[0157] As can be seen, by setting the fourth surface 431 and the fifth surface 432 at an angle relative to the optical film group 23, and connecting the fourth surface 431 and the fifth surface 432 to the two opposite sides of the third surface 111 along its width direction Y, and connecting the sixth surface 433 to the upper side of the third surface 111 along its height direction Z, a tight connection between the middle frame 40 and the liquid crystal glass 11 can be achieved, preventing the liquid crystal glass 11 from shaking during transportation or installation, thereby ensuring the stability of the liquid crystal glass 11. At the same time, since the fourth surface 431 and the fifth surface 432 are both at an angle relative to the third surface 111, and the sixth surface 433 is an arc-shaped surface, this design allows the middle frame 40 to better fit the arc-shaped surface of the liquid crystal glass 11 located on the light-emitting side 11b, further improving the overall assembly stability and reliability of the display device 100.
[0158] In addition, by setting the middle frame 40 to connect the back plate 21 and the liquid crystal glass 11, it can also fix and protect the display panel 10 and the backlight module 20, avoid damage caused by collision or squeezing during transportation or installation, and help extend the service life of the display device 100.
[0159] The display device disclosed in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the display device and its core ideas. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
