Description

Technical Field

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

[0002] Display devices such as televisions, flat panels, or monitors employ backlighting technology to achieve their display functions. Specifically, a display device may include a light source, a reflective sheet, a backlight film, and a display panel. The reflective sheet, backlight film, and display panel are arranged sequentially along a direction parallel to the thickness of the display device. The light source is located on the reflective sheet, which reflects the light from the light source. The light reflected from the reflective sheet passes through the backlight film and illuminates the display panel, enabling the display panel to display images, video, and other information.

[0003] To balance the appearance and cost of display devices, localized thinning is required at the location of the reflective sheet. However, in scenarios involving localized thinning, the reflective sheet's light reflection effect is poor, leading to a subpar display quality. For example, at wide viewing angles such as side views, the display device exhibits uneven brightness. Utility Model Content

[0004] Some embodiments of this application provide a reflector, a backlight module, and a display device to meet the requirements of thinning design while ensuring display effect. The following describes this application from multiple aspects, and the embodiments and beneficial effects of the following aspects can be referred to each other.

[0005] In a first aspect, embodiments of this application provide a reflector. The reflector includes at least one first lamp cup and at least one second lamp cup. The first and second lamp cups are arranged in a direction perpendicular to the thickness direction of the reflector. The height of the first lamp cup is less than the height of the second lamp cup, and the rims of the first and second lamp cups are coplanar, wherein the rims of the first and second lamp cups are perpendicular to the thickness direction.

[0006] In the aforementioned reflector, since the height of the first lamp cup is smaller than that of the second lamp cup, the first lamp cup can be placed in an area with a smaller light mixing distance within the display device containing the reflector; that is, the first lamp cup can be placed in an area requiring thinning. Conversely, the second lamp cup can be placed in an area with a larger light mixing distance; that is, the second lamp cup can be placed in an area where thinning is not required. In this way, the reflector can adapt to the localized thinning design of the display device, balancing the display's appearance and cost.

[0007] Secondly, the rims of the first and second lamp cups are coplanar. This means that the light-emitting surfaces of the first and second lamp cups are located on the same plane. Consequently, there is no height difference between the light-emitting surfaces of the reflector in areas with different mixing distances, and the reflector itself does not have any sloping transition sections. This effectively improves the reflector's light reflection effect, thus avoiding problems with poor display quality. For example, it prevents uneven brightness at wide viewing angles, such as side views.

[0008] In one possible implementation of the first aspect described above, the rim of the first lamp cup has the same shape and size as the rim of the second lamp cup. Since both the first and second lamp cups have focusing properties, by setting the shape and size of the rims of the first and second lamp cups to be the same, the light patterns in the areas where the first and second lamp cups are located can be made approximately the same, thereby effectively improving the uniformity of light mixing and resulting in better light mixing and control effects.

[0009] In one possible implementation of the first aspect described above, the rims of both the first and second lamp cups are rectangular.

[0010] In one possible implementation of the first aspect described above, the inner cavity of the first lamp cup is used to accommodate multiple first light sources. Since the area where the first lamp cup is located is an area with a small mixing distance, accommodating multiple first light sources in the first lamp cup can reduce the spacing between two adjacent first light sources, thereby avoiding the problem of light shadows in areas with small mixing distances and improving the mixing effect in areas with small mixing distances.

[0011] In one possible implementation of the first aspect, a baffle wall is provided in the inner cavity of the first lamp cup, which divides the inner cavity of the first lamp cup into multiple sub-cavities. Each sub-cavity corresponds to a multiple first light source, and each sub-cavity is used to accommodate the corresponding first light source.

[0012] In this way, interference between multiple light sources in the same first lamp cup can be avoided, effectively reducing the difficulty of light control and making it easier to adjust to the desired light mixing effect.

[0013] In one possible implementation of the first aspect described above, the bottom wall of the first lamp cup has multiple first through holes, each penetrating the bottom wall of the first lamp cup along its thickness direction. Each of the multiple first through holes corresponds one-to-one with a multiple first light source, with each first light source disposed within its corresponding first through hole. The multiple first through holes are centrally symmetrically arranged about the geometric center of the bottom wall of the first lamp cup.

[0014] According to the embodiments of this application, a plurality of first through holes can be arranged symmetrically about the geometric center of the bottom wall of the first lamp cup, thereby a plurality of first light sources can be arranged symmetrically about the geometric center of the bottom wall of the first lamp cup. In this way, the overall light path of the first light source in the inner cavity of the first lamp cup is more symmetrical, thereby making the final display effect better.

[0015] In one possible implementation of the first aspect described above, the inner cavity of the second lamp cup is used to accommodate a second light source.

[0016] The area where the second lamp cup is located is a region with a large mixing distance. By accommodating a second light source in the second lamp cup, the mixing needs of the region with a large mixing distance can be met. At the same time, it can also avoid the problem of high cost caused by a large number of light sources.

[0017] In one possible implementation of the first aspect described above, a second through hole is provided in the bottom wall of the second lamp cup, the second through hole penetrating the bottom wall of the second lamp cup along the thickness direction, and the second light source is disposed in the second through hole. The second through hole is located at the geometric center of the bottom wall of the second lamp cup.

[0018] In this way, the second light source can be located at the geometric center of the bottom wall of the second lamp cup, which makes the overall light path of the second light source in the inner cavity of the second lamp cup more symmetrical, thus making the final display effect better.

[0019] In one possible implementation of the first aspect described above, there are multiple first lamp cups and multiple second lamp cups. The multiple first lamp cups are arranged in a first array along a direction perpendicular to the thickness direction, and the multiple second lamp cups are arranged in a second array along a direction perpendicular to the thickness direction. The first array is located in the edge region of the reflector, and the second array is located in the central region of the reflector, with the first array surrounding the second array.

[0020] The aforementioned reflector, by placing the first array of first lamp cups in the edge region and the second array of second lamp cups in the center region, allows the reflector to adapt to the thinning design of the display device where the reflector is located in the edge region.

[0021] In one possible implementation of the first aspect described above, the first and second lamp cups are an integral structure. By designing the first and second lamp cups as an integral structure, the number of components in the reflector can be reduced, the assembly efficiency of the reflector can be improved, and the assembly difficulty of the reflector can be reduced.

[0022] Secondly, embodiments of this application provide a backlight module, which includes a support plate, a first lamp plate, a second lamp plate, a first light source, a second light source, a backlight film, and a reflector as described in the first aspect and any possible implementation thereof. The support plate and the backlight film are disposed opposite each other along the thickness direction, and the first lamp plate, the second lamp plate, the first light source, the second light source, and the reflector are respectively disposed between the support plate and the backlight film. Along the thickness direction, the first light source and the second light source are respectively disposed opposite to different areas of the backlight film, and the first light source is closer to the backlight film than the second light source. The first light source is housed in a first lamp cup of the reflector, which reflects the light from the first light source to the backlight film. The second light source is housed in a second lamp cup of the reflector, which reflects the light from the second light source to the backlight film. The first lamp plate and the second lamp plate are respectively located on the side of the reflector opposite to the backlight film. The first lamp holder has its bottom wall set on the first lamp plate. A first through hole is formed in the bottom wall of the first lamp holder, extending through the bottom wall along its thickness direction. A first light source is disposed in the first through hole and connected to the first lamp plate. The second lamp holder has its bottom wall set on the second lamp plate. A second through hole is formed in the bottom wall of the second lamp holder, extending through the bottom wall along its thickness direction. A second light source is disposed in the second through hole and connected to the second lamp plate.

[0023] It should be understood that the beneficial effects of the second aspect mentioned above can be referred to the description of the first aspect mentioned above, and will not be repeated here.

[0024] In one possible implementation of the second aspect described above, the support plate includes a first region and a second region arranged in a direction perpendicular to the thickness direction. Along the thickness direction, the first region is positioned opposite to a first lamp holder, and the second region is positioned opposite to a second lamp holder. The first region is closer to the backlight film than the second region. Alternatively, along the thickness direction, the distance between the first region and the backlight film is smaller than the distance between the second region and the backlight film. This allows the surface of the support plate facing away from the backlight film to be recessed in the first region, accommodating the thinning design of the backlight module.

[0025] In one possible implementation of the second aspect described above, there are multiple first lamp cups and multiple second lamp cups. The multiple first lamp cups are arranged in a first array along a direction perpendicular to the thickness direction, and the multiple second lamp cups are arranged in a second array along the same direction. The first array is located at the edge region of the reflector, and the second array is located at the center region of the reflector, with the first array surrounding the second array. Furthermore, along the thickness direction, the first region is positioned opposite to the edge region of the reflector, and the second region is positioned opposite to the center region of the reflector.

[0026] In this way, the reflector and support plate can be adapted to the thinning design of the display device where the backlight module is located in the edge area, thus balancing the appearance and cost of the display device.

[0027] Thirdly, embodiments of this application provide a display device, which includes a first light source, a second light source, a backlight film, a display panel, and a reflector as described in the first aspect and any possible implementation thereof. Along the thickness direction, the first light source and the second light source are respectively disposed opposite to different areas of the backlight film, with the first light source being closer to the backlight film than the second light source. The display panel is disposed on the side of the backlight film facing away from the first and second light sources. The first light source is housed in a first lamp cup of the reflector, which reflects light from the first light source onto the backlight film, and the backlight film illuminates the display panel with the light reflected from the first light source. The second light source is housed in a second lamp cup of the reflector, which reflects light from the second light source onto the backlight film, and the backlight film illuminates the display panel with the light reflected from the second light source.

[0028] It should be understood that the beneficial effects of the third aspect mentioned above can be referred to the description of the first aspect mentioned above, and will not be repeated here.

[0029] In one possible implementation of the third aspect described above, the display device further includes a support plate, the support plate and the backlight film being disposed opposite each other along the thickness direction, and the first light source, the second light source and the reflector being disposed between the support plate and the backlight film. The support plate includes a first region and a second region arranged in a direction perpendicular to the thickness direction. Along the thickness direction, the first region is disposed opposite to the first lamp cup, and the second region is disposed opposite to the second lamp cup. The first region is closer to the backlight film than the second region.

[0030] In this way, the reflector and support plate can be adapted to the local thinning design of the display device, thus balancing the appearance and cost of the display device.

[0031] In one possible implementation of the third aspect described above, the size of the edge region of the display device is smaller than the size of the central region of the display device along the thickness direction. There are multiple first lamp cups and multiple second lamp cups, with the multiple first lamp cups arranged in a first array along a direction perpendicular to the thickness direction, and the multiple second lamp cups arranged in a second array along a direction perpendicular to the thickness direction. The first array is located in the edge region of the display device, and the second array is located in the central region of the display device, with the first array surrounding the second array. Furthermore, the first region is located in the edge region of the display device, and the second region is located in the central region of the display device.

[0032] In this way, the reflector and support plate can be adapted to the thinning design of the display device in the edge area, thus balancing the appearance and cost of the display device.

[0033] In one possible implementation of the third aspect described above, the display device further includes a housing, wherein the housing, a support plate, and a reflector are arranged sequentially along a direction parallel to the thickness direction. Along the thickness direction, a first region of the support plate is further away from the housing than a second region of the support plate.

[0034] In this way, thicker components in the display device can be positioned at the corresponding positions of the first lamp cup of the reflector and the first area of ​​the support plate. Both the reflector and the support plate can avoid the component, so the outer shell of the display device can be designed to be relatively flat without local bulges, which helps to achieve the local thinning design of the display device.

[0035] In one possible implementation of the third aspect described above, the display device further includes a functional device disposed between the housing and the first region, wherein the size of the functional device is greater than the distance between the second region and the housing along the thickness direction.

[0036] By placing the functional components between the housing and the first area of ​​the support plate, the height difference between the functional components and other components can be absorbed, thereby avoiding additional increase in the size of the display device along the thickness direction, and thus satisfying the thinning design of the display device in the area where the functional components are located.

[0037] In one possible implementation of the third aspect described above, the display device further includes a first lamp board located on the side of the reflector facing away from the backlight film. The bottom wall of a first lamp cup is disposed on the first lamp board, and a first through hole is formed on the bottom wall of the first lamp cup, the first through hole penetrating the bottom wall of the first lamp cup along the thickness direction, and a first light source is disposed in the first through hole and connected to the first lamp board.

[0038] According to an embodiment of this application, a first light source can be connected to a first lamp board via a first through hole. The first lamp board can transmit signals to the first light source to control the working state of the first light source, such as controlling whether the first light source emits light, controlling the brightness and color of the light emitted by the first light source, etc. Attached Figure Description

[0061] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0062] This application provides a reflector, a backlight module including the reflector, and a display device. The reflector provided by this application can balance the installation requirements of localized thinning scenarios with the display effect of the display device.

[0063] The following describes specific embodiments of this application. In the following specific embodiments, a television is used as an example of a display device, but this application is not limited thereto. In other embodiments, the display device may also be a tablet computer, a conference display device, an in-vehicle display device, a billboard, or other electronic device with display functions.

[0064] Figure 1 An exemplary structure of display device 1 according to one embodiment of this application is shown. (Reference) Figure 1 The display device 1 may include a display panel 10 and a housing 20.

[0065] The display panel 10 can also be referred to as a "screen". The display panel 10 is used to display images and videos, and can also integrate touch functionality. It is understood that the display panel 10 can be a liquid crystal display (LCD) panel, an organic light-emitting diode (OLED) display panel, a quantum dot light-emitting diode (QLED) display panel, or a miniature light-emitting diode (MiniLED), etc., and this application does not impose specific limitations on this.

[0066] The display panel 10 can be mounted on the housing 20, and the display panel 10 and the housing 20 can together form a cavity 30. The cavity 30 is used to house the components of the display device 1, such as light sources, reflective sheets, and backlight films, which are used to realize the display function. The cavity 30 can be a basically closed structure, thereby providing moisture protection, dust protection, and mechanical protection for the components inside the cavity 30.

[0067] It is understood that both the display panel 10 and the housing 20 are external components of the display device 1. That is, after the display device 1 is assembled, the display panel 10 and the housing 20 can be observed or touched.

[0068] based on Figure 1 As shown in the diagram, the display device 1 may have an edge region A1 and a central region A2. The edge region A1 of the display device 1 may be the region near the junction of the display panel 10 and the housing 20. For example, the edge region A1 may be... Figure 1 A ring-shaped area filled with dots. The central area A2 of display device 1 can be: the area in display device 1 mainly used to display image and video information, which is usually the area where the user's visual focus is concentrated. For example, the central area A2 can be: Figure 1 The area is a rectangular region filled with grid lines. The edge region A1 has a ring-like structure and surrounds the central region A2.

[0069] Figure 2 The diagram shows enlarged views of the cavity 30 of display device 1 in some technical solutions, specifically in the edge region A1 and the central region A2. (Reference) Figure 2 The cavity 30 of the display device 1 may be equipped with a light source 40, a reflective sheet 50 and a backlight film 60 to realize the display function of the display device 1.

[0070] The light source 40 is used to emit light. For example, the light source 40 can be a light-emitting diode (LED) lamp. There can be multiple light sources 40, for example, two, three, four, or five. Multiple light sources 40 can be arranged in an array, for example, a rectangular array.

[0071] The reflective sheet 50, the backlight film 60, and the display panel 10 are arranged sequentially along the Z1 direction. The Z1 direction is parallel to the thickness direction of the display device 1, which can be, for example, the thickness direction of the display device 1. Figure 2 The Z direction is shown.

[0072] The reflective sheet 50 has a planar sheet-like structure. It concentrates and reflects the light from the light source 40 onto the upper backlight film 60, increasing light utilization. The light reflected from the reflective sheet 50 can then be projected onto the display panel 10 via the backlight film 60, thereby enabling the display function of the display device 1.

[0073] The backlight film 60 is an optical film used to process light. The backlight film 60 may include one or more optical films. For example, the backlight film 60 may include a diffusion film, which can uniformly diffuse and atomize light to give the display panel 10 a more uniform brightness during display. Alternatively, the backlight film 60 may also include a brightness enhancement film, which can concentrate the diffused light to increase the display brightness of the display panel 10 within the viewing angle range. Furthermore, the backlight film 60 may also be a combination of multiple optical films such as diffusion films and brightness enhancement films.

[0074] Continue to refer to Figure 2 The distance between the light source 40 and the backlight film 60 (e.g., the first distance D1 and the second distance D2) can be referred to as the "optical distance (OD)". A larger optical distance allows more space for the light from the light source 40 to mix before reaching the backlight film 60, resulting in more uniform light distribution and less noticeable shadows, leading to a better display effect. A smaller optical distance requires less space in the Z-direction for the light source 40 and the backlight film 60, facilitating a thinner design for the display device 1 and improving its aesthetic appearance. However, as the optical distance decreases, the spacing between adjacent light sources 40 also needs to be reduced to improve the optical mixing effect. In other words, a smaller optical distance requires more light sources 40, increasing the cost of the display device 1.

[0075] To balance the appearance and cost of display device 1, display device 1 can be locally thinned. For example, in Figure 2 In the illustrated scheme, along the Z-direction, the size d1 of the edge region A1 of display device 1 is smaller than the size d2 of the central region A2 of display device 1. In the edge region A1 of display device 1, the light mixing distance is a first distance D1. Since the first distance D1 is relatively small, the light mixing effect can be ensured by increasing the number of light sources 40 to reduce the light source spacing. In the central region A2 of display device 2, the light mixing distance is a second distance D2. Since the second distance D2 is greater than the first distance D1, the light source spacing can be set to be larger, thus eliminating the need to increase the number of light sources 40 and controlling costs.

[0076] To accommodate the localized thinning design of the display device 1, the reflective sheet 50 may include a first sheet-like portion 510, a second sheet-like portion 520, and a third sheet-like portion 530. The first sheet-like portion 510 is located in the edge region A1 of the display device 1, and the second sheet-like portion 520 is located in the central region A2 of the display device 1. Along the Z-direction, the first sheet-like portion 510 is closer to the backlight film 60 than the second sheet-like portion 520; in other words, the first sheet-like portion 510 and the second sheet-like portion 520 have a height difference. The third sheet-like portion 530 serves as a transition section, generally resembling a slope, to connect the first sheet-like portion 510 and the second sheet-like portion 520 at different heights. It can be understood that the surfaces of the first sheet-like portion 510, the second sheet-like portion 520, and the third sheet-like portion 530 facing the backlight film 60 together constitute the light-emitting surface of the reflective sheet 50.

[0077] The aforementioned reflective sheet 50 has light-emitting surfaces located on different planes in areas with different light mixing distances, resulting in height differences between the light-emitting surfaces. Furthermore, the slope of the transitional third sheet portion 530 varies considerably and is significantly affected by assembly precision. These slope variations and height differences affect the light reflection effect of the third sheet portion 530, leading to poor display performance of the display device 1. For example, at wide viewing angles such as side views, the display device 1 exhibits uneven brightness.

[0078] In view of this, this application provides a three-dimensional reflector to replace the two-dimensional sheet-like reflector in the aforementioned display device. The reflector provided by this application may include multiple lamp cups for accommodating a light source. Each lamp cup reflects light from the light source, and the reflected light exits from the rim of the lamp cup; that is, the rim of the lamp cup is the light-emitting surface of the reflector. The lamp cups have different heights. Lamp cups with smaller heights are used in areas with shorter mixing distances, while lamp cups with larger heights are used in areas with longer mixing distances. This accommodates the localized thinning design of the display device, thereby balancing the appearance and cost of the display device. Furthermore, the rims of the multiple lamp cups are coplanar, meaning that the light-emitting surfaces of the reflector in areas with different mixing distances are on the same plane, with no height difference between the light-emitting surfaces. The reflector also lacks sloping transition sections, thus avoiding the aforementioned problems of poor display quality caused by changes in slope and height.

[0079] The technical solution of this application is described below with reference to the accompanying drawings.

[0080] Figure 3A This application illustrates an exemplary configuration of a reflector 70 in a display device 1, wherein... Figure 3A Only a portion of the structure in display device 1 is shown. Figure 3B according to Figure 3A A top view of the reflector 70 in an embodiment of this application is shown. For ease of observation, Figure 3BThe area filled with dots shows the rim surface F1 of the first lamp cup 710, and the area filled with a grid shows the rim surface F2 of the second lamp cup 720. Figure 3B The first light source 410 and the second light source 420 are also shown in dashed lines.

[0081] refer to Figure 3A and Figure 3B The reflector 70 may include at least one first lamp cup 710 and at least one second lamp cup 720. For ease of description, one of the first lamp cups 710 and one of the second lamp cups 720 will be used as examples below.

[0082] The first lamp cup 710 has a cup-like structure. For example, the first lamp cup 710 may include a bottom wall 711 and a side wall 712. The side wall 712 surrounds the bottom wall 711 and stands sideways relative to the bottom wall 711 in the Z direction, thereby forming the inner cavity S1 of the first lamp cup 710. The plane of the side wall 712 facing away from the bottom wall 711 in the Z direction constitutes the cup mouth surface F1 of the first lamp cup 710.

[0083] Similarly, the second lamp cup 720 also has a cup-shaped structure. For example, the second lamp cup 720 may include a bottom wall 721 and a side wall 722. The side wall 722 surrounds the bottom wall 721 and stands sideways relative to the bottom wall 721 in the Z direction, thereby forming the inner cavity S2 of the second lamp cup 720. The plane containing the surface of the side wall 722 facing away from the bottom wall 721 in the Z direction constitutes the cup rim surface F2 of the second lamp cup 720.

[0084] The first lamp holder 710 and the second lamp holder 720 are arranged in a direction perpendicular to the thickness direction of the reflector 70. For example, the thickness direction of the reflector 70 can be the Z direction, and the first lamp holder 710 and the second lamp holder 720 can be arranged in the X direction, which is perpendicular to the Z direction.

[0085] The height H1 of the first lamp cup 710 is less than the height H2 of the second lamp cup 720, or in other words, the layout space occupied by the first lamp cup 710 in the Z direction is less than the layout space occupied by the second lamp cup 720 in the Z direction. Here, the height of the lamp cup refers to the dimension of the lamp cup along the Z direction.

[0086] The rim surface F1 of the first lamp cup 710 and the rim surface F2 of the second lamp cup 720 are coplanar and perpendicular to the Z direction. Here, the rim surface of the lamp cup refers to the opening part of the lamp cup, which is used to allow light from the light source inside the lamp cup to be emitted from inside the lamp cup to the outside of the lamp cup. Therefore, the rim surface of the lamp cup can also be called the "light-emitting surface".

[0087] It is understood that the coplanarity in this application is not absolute coplanarity. Approximate coplanarity due to processing and assembly errors is also within the scope of coplanarity in this application. For example, the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 can be approximately parallel and substantially in the same plane. That is, there can be an included angle between the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 within a certain range, for example, the included angle range can be 0 to 0.1°. Alternatively, there can be a distance between the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 within a certain range, for example, the distance range can be 0 to 0.1 mm.

[0088] Furthermore, it should be understood that the perpendicularity in this application is not absolute. Approximate perpendicularity due to processing and assembly errors (e.g., an angle of 89.9° between two structural features) is also within the scope of perpendicularity in this application. Similarly, the parallelism in this application is not absolute. Approximate parallelism due to processing and assembly errors (e.g., an angle of 0.1° between two structural features) is also within the scope of parallelism in this application.

[0089] Since the cup height H1 of the first lamp cup 710 is smaller than the cup height H2 of the second lamp cup 720, the first lamp cup 710 can be placed in an area of ​​the display device 1 with a smaller light mixing distance, i.e., an area of ​​the display device 1 that requires thinning. Similarly, the second lamp cup 720 can be placed in an area of ​​the display device 1 with a larger light mixing distance, i.e., an area of ​​the display device 1 that does not require thinning. In this way, the reflector 70 can adapt to the localized thinning design of the display device 1, balancing the appearance and cost of the display device 1.

[0090] Secondly, the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 are coplanar, compared to the above. Figure 2 In the illustrated scheme, the light-emitting surfaces of the reflector 50 and reflector 70 in regions with different light mixing distances are on the same plane, with no height difference between the light-emitting surfaces, and the reflector 70 does not have a sloping transition section. Therefore, the aforementioned issues can be avoided. Figure 2 The solution shown addresses the issue of poor display quality caused by slope variations and height differences. For example, it avoids the problem of uneven brightness in display device 1 at large viewing angles such as side views.

[0091] To facilitate understanding of the reflective effect of the reflector 70 provided in this application, the following description is provided in conjunction with the specific structure of the display device 1.

[0092] Continue to refer to Figure 3AThe display device 1 provided in this application may include a display panel 10, a first light source 410, a second light source 420, a backlight film 60, and a reflector 70. The specific structure and function of the display panel 10 are as described above. Figure 2 The display panel 10 in the illustrated scheme is essentially the same, and the specific structure and function of the first light source 410 and the second light source 420 are the same as described above. Figure 2 The light source 40 in the illustrated scheme is essentially the same, and the specific structure and function of the backlight film 60 are the same as described above. Figure 2 The backlight film 60 in the illustrated scheme is essentially the same, therefore it can be referred to the above. Figure 2 The relevant descriptions in the illustrated scheme will not be repeated here. The following describes the arrangement and working principle of the display panel 10, the first light source 410, the second light source 420, the backlight film 60, and the reflector 70.

[0093] Continue to refer to Figure 3A Along the Z-direction, the first light source 410 and the second light source 420 are respectively disposed opposite to different areas of the backlight film 60. Alternatively, the first light source 410 and the second light source 420 are arranged in a direction perpendicular to the Z-direction (e.g., the X-direction), and the first light source 410 and the second light source 420 are respectively disposed opposite to the backlight film 60 along the Z-direction.

[0094] Along the Z-direction, the first light source 410 is closer to the backlight film 60 than the second light source 420. Therefore, the distance between the first light source 410 and the backlight film 60 is smaller than the distance between the second light source 420 and the backlight film 60. In other words, the area where the first light source 410 is located has a smaller light mixing distance, which is the area in the display device 1 that needs to be thinned, and the light mixing distance in this area can be a first distance D1. Conversely, the area where the second light source 420 is located has a larger light mixing distance, which is the area in the display device 1 that does not need to be thinned, and the light mixing distance in this area can be a second distance D2, which is greater than the first distance D1.

[0095] Along the Z-direction, the display panel 10 is disposed on the side of the backlight film 60 that faces away from the first light source 410 and the second light source 420, for example, in Figure 3A In the embodiment shown, the first light source 410, the backlight film 60, and the display panel 10 are arranged sequentially along the Z1 direction, and the second light source 420, the backlight film 60, and the display panel 10 are arranged sequentially along the Z1 direction.

[0096] The first light source 410 is housed within the first lamp cup 710 of the reflector 70. For example, in Figure 3A In the illustrated embodiment, the first light source 410 can be disposed on the bottom wall 711 of the first lamp cup 710 and extend into the inner cavity S1 of the first lamp cup 710. The second light source 420 is accommodated in the second lamp cup 720 of the reflector 70. For example, in Figure 3AIn the illustrated embodiment, the second light source 420 can be disposed on the bottom wall 721 of the second lamp cup 720 and extend into the inner cavity S2 of the second lamp cup 720. Since the cup height H1 of the first lamp cup 710 is smaller than the cup height H2 of the second lamp cup 720, the reflector 70 can be adapted to the local thinning design of the display device 1 to balance the appearance and cost of the display device 1.

[0097] The first lamp cup 710 is used to reflect the light from the first light source 410 to the backlight film 60, the second lamp cup 720 is used to reflect the light from the second light source 420 to the backlight film 60, and the backlight film 60 is used to illuminate the display panel 10 with the light from the first light source 410 reflected by the first lamp cup 710 and the light from the second light source 420 reflected by the second lamp cup 720, so as to realize the display function of the display device 1.

[0098] For example, Figure 3C according to Figure 3A A schematic diagram of light propagation in reflector 70 according to an embodiment of this application is shown. (Reference) Figure 3C The first light source 410 can emit light. Taking one of the light rays L1 as an example, the light ray L1 shines on the side wall 712 of the first lamp cup 710. Then the side wall 712 of the first lamp cup 710 can reflect the light ray L1. The reflected light ray L1 can be emitted from the inner cavity S1 of the first lamp cup 710 to the outside of the first lamp cup 710 through the cup mouth surface F1.

[0099] Similarly, the second light source 420 can also emit light. Taking one of the light rays L2 as an example, the light ray L2 shines on the side wall 722 of the second lamp cup 720, and then the side wall 722 of the second lamp cup 720 can reflect the light ray L2. The reflected light ray L2 can be emitted from the inner cavity S2 of the second lamp cup 720 to the outside of the second lamp cup 720 through the cup mouth surface F2.

[0100] Since the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 are coplanar, meaning that the light-emitting surface from which the light L1 is emitted by the first lamp cup 710 and the light-emitting surface from which the light L2 is emitted by the second lamp cup 720 are located on the same plane, there is no height difference between the light-emitting surfaces of the reflector 70 in areas with different mixing distances, and the reflector 70 does not have a sloping transition section. This effectively improves the reflection effect of the reflector 70 on the light L1 from the first light source 410 and the light L2 from the second light source 420, thereby avoiding the aforementioned... Figure 2 The solution shown addresses the issue of poor display quality caused by slope variations and height differences. For example, it avoids the problem of uneven brightness in display device 1 at large viewing angles such as side views.

[0101] It is understood that the display device 1 provided in this application can be locally thinned in any area. Depending on the area in the display device 1 that needs to be thinned, the arrangement of the first lamp cup 710 and the second lamp cup 720 in the reflector 70 can also be different, as illustrated below with reference to the accompanying drawings.

[0102] Continue to refer to Figure 3A In some feasible solutions, along the Z-direction, the size d1 of the edge region A1 of the display device 1 can be smaller than the size d2 of the central region A2 of the display device 1. Thus, the edge region A1 has a smaller light mixing distance, while the central region A2 has a larger light mixing distance. That is, the display device 1 is thinned in the edge region A1, thereby achieving an ultra-thin edge appearance. Correspondingly, the first lamp cup 710 of the reflector 70 can be disposed in the edge region A1 of the display device 1, and the second lamp cup 720 of the reflector 70 can be disposed in the central region A2 of the display device 1.

[0103] Based on this, continue to refer to Figure 3B and combined Figure 3A In some embodiments of this application, the number of first lamp cups 710 and second lamp cups 720 can each be multiple. The multiple first lamp cups 710 can be arranged in a first array N1 along a direction perpendicular to the Z direction; that is, the first array N1 is a planar array, and the first array N1 is arranged perpendicular to the Z direction. The first array N1 is located in the edge region A3 of the reflector 70, wherein the edge region A3 of the reflector 70 is perpendicular to the Z direction. Figure 3A In the illustrated embodiment, the edge region A1 of the display device 1 corresponds to, or in other words, when the reflector 70 is installed in the display device 1, the edge region A3 of the reflector 70 is located in the edge region A1 of the display device 1. Therefore, it can also be understood that the first array N1 is located in the edge region A1 of the display device 1, that is, the plurality of first lamp cups 710 are located in the edge region A1 of the display device 1.

[0104] Multiple second lamp cups 720 can be arranged in a second array N2 along a direction perpendicular to the Z direction; that is, the second array N2 is a planar array, and the second array N2 is set perpendicular to the Z direction. The second array N2 is located in the central region A4 of the reflector 70, wherein the central region A4 of the reflector 70 is perpendicular to the Z direction. Figure 3A In the illustrated embodiment, the central region A2 of the display device 1 corresponds to, or in other words, when the reflector 70 is installed in the display device 1, the central region A4 of the reflector 70 is located in the central region A2 of the display device 1. Therefore, it can also be understood that the second array N2 is located in the central region A2 of the display device 1, that is, the plurality of second lamp cups 720 are located in the central region A2 of the display device 1.

[0105] The edge region A1 of the display device 1 can surround the central region A2, and correspondingly, the first array N1 located in the edge region A1 surrounds the second array N2 located in the central region A2. In this application, "component A surrounds component B" means that component A completely or partially surrounds component B in space. For example, component A can be a closed ring structure, surrounding the four sides of component B. Alternatively, component A can be an open structure, surrounding a portion of component B. For example, component A can be an L-shaped structure, component B can be a rectangular structure, and component A can surround adjacent sides of component B.

[0106] The aforementioned reflector 70 can be adapted to the thinning design of the display device 1 in the edge region A1 by setting the first array N1 of the first lamp cups 710 in the edge region A1 and the second array N2 of the second lamp cups 720 in the center region A2.

[0107] Continue reading Figure 3B In some implementations, multiple first lamp cups 710 can be arranged along direction A to form a circular first array N1. The circumferential direction of the circular first array N1 can be, for example, direction A, which is perpendicular to the Z direction (e.g., Figure 3B (in the direction perpendicular to the paper). In the embodiment shown in 3B, the number of first lamp cups 710 can be one in the radial direction of the first array N1 (e.g., in the direction perpendicular to the A and Z directions), therefore, the first array N1 can be a single-ring rectangular ring array.

[0108] Figure 4 This illustrates another arrangement of the first lamp cup 710 in an embodiment of this application. (See reference...) Figure 4 In some other implementations, multiple first lamp cups 710 can be arranged along direction A and in directions perpendicular to both directions A and Z, thereby forming a ring-shaped first array N1. The radial direction of the ring-shaped first array N1 can, for example, be perpendicular to both directions A and Z. Figure 4 The direction perpendicular to the paper (in the middle). Figure 4 In the illustrated embodiment, the number of first lamp cups 710 in the radial direction of the first array N1 can be two. Therefore, the first array N1 can be a double-ring rectangular ring array.

[0109] It is understandable that the above Figure 3B and Figure 4This illustration merely shows several arrangements of the multiple first lamp cups 710 and does not constitute a limitation on this application. For example, in some other implementations, the multiple first lamp cups 710 can also be arranged into a first array N1 of more rings. Furthermore, in yet another implementation, the first array N1 formed by the multiple first lamp cups 710 can be a regular ring array such as a circular ring array or a regular pentagonal ring array, or other irregular ring arrays.

[0110] Continue reading Figure 3B In some implementations, multiple second lamp cups 720 can be arranged along the X and Y directions to form a rectangular second array N2. The column direction of the rectangular second array N2 can be, for example, the X direction, and the row direction can be, for example, the Y direction. The X, Y, and Z directions (e.g., ...) Figure 3B (The directions perpendicular to the paper) are mutually perpendicular.

[0111] In some other implementations, the second array N2 can also be a regular array such as a circular array or a regular pentagonal array, or other irregular arrays. This application does not impose specific restrictions on this.

[0112] For ease of description, we will continue with... Figures 3A to 3C The first lamp holder 710 and the second lamp holder 720 in the reflector 70 shown are examples illustrating the specific structure of the reflector 70 provided in the embodiments of this application. It can be understood that... Figure 4 The first lamp cup 710 and the second lamp cup 720 in the reflector 70 shown are... Figures 3A to 3C The first lamp cup 710 and the second lamp cup 720 in the reflector 70 shown have essentially the same structure, so they will not be described in detail again.

[0113] Continue to refer to Figures 3A to 3C In some embodiments of this application, the first lamp cup 710 and the second lamp cup 720 can be an integral structure, that is, the first lamp cup 710 and the second lamp cup 720 are integrally formed. For example, the materials of the first lamp cup 710 and the second lamp cup 720 can be integrally formed by a mold vacuum forming process. By designing the first lamp cup 710 and the second lamp cup 720 as an integral structure, the number of parts of the reflector 70 can be reduced, the assembly efficiency of the reflector 70 can be improved, and the assembly difficulty of the reflector 70 can be reduced.

[0114] Continue to refer to Figures 3A to 3CIn some embodiments of this application, the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 can have the same shape and size. Since the first lamp cup 710 and the second lamp cup 720 have light-focusing characteristics, by setting the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 to be the same shape and size, the light patterns of different areas of the display device 1 can be made to be approximately the same. For example, the light pattern of the edge area A1 of the display device 1 and the light pattern of the center area A2 of the display device 1 are approximately the same, thereby effectively improving the light mixing uniformity of the display device 1, and thus making the light mixing effect and light control effect of the display device 1 better.

[0115] In this application, the light pattern refers to the shape and size of the light spot formed on the target area after the light from the light source is reflected by the reflector. For example, the light pattern of the edge area A1 of the display device 1 can refer to the shape and size of the light spot formed on the backlight film 60 after the light from the first light source 410 is reflected by the first lamp cup 710; the light pattern of the center area A2 of the display device 1 can refer to the shape and size of the light spot formed on the backlight film 60 after the light from the second light source 420 is reflected by the second lamp cup 720.

[0116] In some implementations, the cup-mouth surface F1 of the first lamp cup 710 and the cup-mouth surface F2 of the second lamp cup 720 can both be square. The side length a1 of the cup-mouth surface F1 of the first lamp cup 710 and the side length a2 of the cup-mouth surface F2 of the second lamp cup 720 can be the same, making the cup-mouth surfaces F1 and F2 of the first lamp cup 710 the same size. This results in the light pattern in the region with a smaller mixing distance of the first lamp cup 710 being approximately the same as the light pattern in the region with a larger mixing distance of the second lamp cup 720, thereby effectively improving the uniformity of light mixing. The region with a smaller mixing distance of the first lamp cup 710 can be, for example, the edge region A1 of the display device 1, and the region with a larger mixing distance of the second lamp cup 720 can be, for example, the central region A2 of the display device 1.

[0117] For example, Figure 5A according to Figures 3A to 3C A simulation diagram of the light pattern of the edge region A1 of the display device 1 in this embodiment is shown. Figure 5B according to Figures 3A to 3C A simulated light pattern diagram of the central region A2 of the display device 1 in an embodiment of this application is shown. (Reference) Figure 5A In areas with a small mixing distance, the light spot formed by the light from the first light source 410 reflected by the first lamp cup 710 is called light spot M1. (Reference) Figure 5B In areas with a large mixing distance, the light spot formed by the light from the second light source 420 reflected by the second lamp cup 720 is light spot M2. (Comparison) Figure 5A and Figure 5B Both light spots M1 and M2 are square in shape, and they are the same size. For example, the side length b1 of light spot M1 and the side length b2 of light spot M2 are the same. As a result, the light patterns of the areas with smaller light mixing distances are the same as those of the areas with larger light mixing distances, resulting in good light mixing uniformity.

[0118] It should be noted that the same size in this application is not an absolute sameness; approximate sameness due to processing and assembly errors is also within the scope of sameness in this application. For example, in Figure 3B and Figure 3C In the illustrated embodiment, the side length a1 of the rim surface F1 of the first lamp cup 710 and the side length a2 of the rim surface F2 of the second lamp cup 720 can be approximately the same. That is, the ratio between the side length a1 of the rim surface F1 of the first lamp cup 710 and the side length a2 of the rim surface F2 of the second lamp cup 720 can be within a certain range, for example, 0.9 to 1.1. For example, in... Figure 5A and Figure 5B In the embodiment shown, the side length b1 of spot M1 and the side length b2 of spot M2 can be approximately the same, that is, the ratio between the side length b1 of spot M1 and the side length b2 of spot M2 can be within a certain range, for example, 0.9 to 1.1.

[0119] It is understandable that the above Figures 3A to 5B In the illustrated embodiment, the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 are both square. This is merely illustrative and does not constitute a limitation of this application. In other alternative implementations, the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 can also be other shapes. For example, the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 can also be circular or regular pentagonal shapes. This application does not impose specific limitations in this regard, as long as the actual usage requirements are met.

[0120] When the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 are both circular, the diameter of the cup rim surface F1 of the first lamp cup 710 and the diameter of the cup rim surface F2 of the second lamp cup 720 can be the same, so that the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 are the same size.

[0121] When the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 are both regular pentagons, the side length of the cup rim surface F1 of the first lamp cup 710 and the side length of the cup rim surface F2 of the second lamp cup 720 can be the same, so that the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 are the same size.

[0122] Compared to the above Figure 2 As shown in the diagram, the reflector 70 provided in this application can effectively avoid the problem of light mixing uniformity caused by light pattern mismatch by setting the shape and size of the cup surface F1 of the first lamp cup 710 and the cup surface F2 of the second lamp cup 720 to be the same.

[0123] Specifically, in Figure 2 In the illustrated scheme, the reflector 50 has a sloping transition section, namely the third sheet portion 530. No light source 40 is provided on the third sheet portion 530. In the area near the third sheet portion 530, the distance between two adjacent light sources 40 is relatively large, while in other areas, such as the areas where the first sheet portion 510 and the second sheet portion 520 are located, the distance between two adjacent light sources 40 is relatively small. Due to the different distances between adjacent light sources 40, the light pattern in the area of ​​the third sheet portion 530 is fragmented and uneven, thus affecting the uniformity of light mixing and resulting in poor overall frontal viewing angle light mixing uniformity and light control effect. In this application, by setting the shape and size of the cup surface F1 of the first lamp cup 710 and the cup surface F2 of the second lamp cup 720 to be the same, the shape and size of the light spots formed by the light from the first light source 410 and the second light source 420 can be made consistent. This ensures that the light patterns in different areas of the display device where the reflector 70 is located are approximately the same, achieving uniformity of light patterns in different areas, thereby improving the frontal viewing angle light mixing uniformity and light control effect.

[0124] The relative arrangement of the first light source 410 and the first lamp cup 710, and the relative arrangement of the second light source 420 and the second lamp cup 720 are described below with reference to the accompanying drawings.

[0125] Continue to refer to Figure 3A and Figure 3B In some embodiments of this application, the inner cavity S1 of the first lamp cup 710 can be used to accommodate multiple first light sources 410, such as two, three, four, or five. As mentioned above, the area where the first lamp cup 710 is located is an area with a small light mixing distance. By accommodating multiple first light sources 410 in the first lamp cup 710, the distance G1 between two adjacent first light sources 410 can be smaller, thereby avoiding the problem of light shadows in the area with a small light mixing distance, and thus improving the light mixing effect in the area with a small light mixing distance.

[0126] It is understood that this application does not impose a specific limit on the number of first light sources 410 that the first lamp cup 710 can accommodate, as long as the spacing G1 between two adjacent first light sources 410 can meet the actual light mixing requirements.

[0127] In some implementations, the number of first light sources 410 can be associated with a first distance D1. Specifically, the smaller the first distance D1, the smaller the spacing G1 between two adjacent first light sources 410, that is, the denser the arrangement of multiple first light sources 410, so that the number of first light sources 410 is greater when the size of the inner cavity S1 of the first lamp cup 710 remains unchanged; conversely, the larger the first distance D1, the larger the spacing G1 between two adjacent first light sources 410, that is, the sparser the arrangement of multiple first light sources 410, so that the number of first light sources 410 is less when the size of the inner cavity S1 of the first lamp cup 710 remains unchanged.

[0128] For example, the ratio between the spacing G1 between two adjacent first light sources 410 and the first distance D1 can be in the range of 2 to 5, for example, 2, 3, 4 or 5.

[0129] In some implementations, the number of first light sources 410 can be related to the size of the inner cavity S1 of the first lamp cup 710. With the spacing G1 between two adjacent first light sources 410 remaining constant, the larger the inner cavity S1 of the first lamp cup 710, the more first light sources 410 there are; conversely, the smaller the inner cavity S1 of the first lamp cup 710, the fewer first light sources 410 there are.

[0130] In some implementations, the number of first light sources 410 can be related to their light-diffusing performance. The better the light-diffusing performance of the first light source 410, the wider the area its light can spread during propagation, resulting in a better mixing effect among multiple first light sources 410. Therefore, the number of first light sources 410 can be set less. Conversely, the worse the light-diffusing performance of the first light source 410, the more first light sources 410 need to be set to ensure a good mixing effect.

[0131] In some implementations, multiple first light sources 410 can be arranged in an array within the cavity S1 of the first lamp cup 710, such as a rectangular array or a circular array. This application does not impose any specific limitations on this.

[0132] Continue to refer to Figure 3A and Figure 3B In some embodiments of this application, the bottom wall 711 of the first lamp cup 710 may have multiple first through holes 713. These multiple first through holes 713 penetrate the bottom wall 711 of the first lamp cup 710 along the Z-direction, thereby connecting the inner cavity S1 of the first lamp cup 710 and the outside of the first lamp cup 710. Each of the multiple first through holes 713 corresponds one-to-one with a multiple first light source 410, and each first light source 410 may be disposed in its corresponding first through hole 713.

[0133] Thus, on the one hand, the first light source 410 can extend into the inner cavity S1 of the first lamp cup 710 through the first through hole 713, and the light from the first light source 410 can propagate in the inner cavity S1 of the first lamp cup 710 and be emitted from the inner cavity S1 of the first lamp cup 710 through the cup rim F1. It can be understood that the cup rim F1 of the first lamp cup 710 and the first through hole 713 are arranged at intervals along the Z direction.

[0134] On the other hand, the first light source 410 can also be connected to other devices outside the first lamp cup 710 via the first through hole 713. For example, in some implementations, the display device 1 may also include a first lamp board 411, which is located on the side of the reflector 70 facing away from the backlight film 60, or in other words, the first lamp board 411, the reflector 70, and the backlight film 60 are arranged sequentially along the Z1 direction. The bottom wall 711 of the first lamp cup 710 of the reflector 70 is disposed on the first lamp board 411. Exemplarily, the bottom wall 711 of the first lamp cup 710 can be connected to the first lamp board 411 by means of adhesion, snap-fit, or fastener connection. The first light source 410 can be connected to the first lamp board 411 via the first through hole 713. The first lamp board 411 can transmit signals to the first light source 410 to control the working state of the first light source 410, such as controlling whether the first light source 410 emits light, controlling the brightness and color of the light emitted by the first light source 410, etc.

[0135] In some implementations, multiple first through holes 713 can be arranged symmetrically about the geometric center O1 of the bottom wall 711 of the first lamp cup 710. Thus, multiple first light sources 410 can be arranged symmetrically about the geometric center O1 of the bottom wall 711 of the first lamp cup 710. This makes the overall light path of the first light source 410 in the inner cavity S1 of the first lamp cup 710 more symmetrical, thereby making the final display effect better.

[0136] It is understandable that, depending on the shape of the bottom wall 711 of the first lamp cup 710, the position of the geometric center O1 corresponding to the bottom wall 711 of the first lamp cup 710 can be different. For example, in Figure 3B In the illustrated embodiment, the overall shape of the bottom wall 711 of the first lamp cup 710 is approximately a rectangle enclosed by dotted lines. In this case, the geometric center O1 of the bottom wall 711 of the first lamp cup 710 can be the intersection of the diagonals of the rectangle. Alternatively, if the overall shape of the bottom wall 711 of the first lamp cup 710 is circular, its corresponding geometric center O1 can be the center of the circular bottom wall 711. Furthermore, if the overall shape of the bottom wall 711 of the first lamp cup 710 is a regular pentagon, its corresponding geometric center O1 can be a point on the regular pentagonal bottom wall 711 that is equidistant from each side.

[0137] Continue to refer to Figure 3A and Figure 3B, in some embodiments of the present application, a partition wall 714 may be provided in the inner cavity S1 of the first lamp cup 710. The partition wall 714 may divide the inner cavity S1 of the first lamp cup 710 into multiple sub-cavities S11. The multiple sub-cavities S11 correspond to the multiple first light sources 410 one by one, and each sub-cavity S11 can accommodate the corresponding first light source 410. In this way, the multiple first light sources 410 in the same first lamp cup 710 can be prevented from interfering with each other, effectively reducing the difficulty of light control, and thus it is easier to adjust to the required mixed light effect.

[0138] It can be understood that the partition wall 714 is located in the inner cavity S1 of the first lamp cup 710. Therefore, the height H3 of the partition wall 714 can be less than or equal to the cup height Hl of the first lamp cup 710. Wherein, the height H3 of the partition wall 714 is the dimension of the partition wall 714 along the Z direction.

[0139] In addition, it can be understood that based on the different numbers and arrangements of the multiple first light sources 410, the partition wall 714 can have different structural forms.

[0140] For example, in Figure 3B the shown embodiment, four first light sources 410 can be accommodated in the inner cavity S1 of the first lamp cup 710, and the four first light sources 410 are arranged in a 2×2 rectangular array. Correspondingly, the partition wall 714 is a cross-shaped structure, so that the first lamp cup 710 is similar to a field character shape, and the inner cavity S1 of the first lamp cup 710 can be divided into four sub-cavities S11 by the cross-shaped partition wall 714, and each sub-cavity S11 accommodates one first light source 410.

[0141] Another example is Figure 6 which shows an exemplary structure of a first lamp cup 710 in an embodiment of the present application, and the first light source 410 is shown by a dotted line. Referring to Figure 6 , in some other alternative embodiments, two first light sources 410 can also be accommodated in the inner cavity S1 of the first lamp cup 710, and the two first light sources 410 are arranged along the Y direction. Correspondingly, the partition wall 714 can be a linear structure, so that the first lamp cup 710 is similar to a Japanese character shape, and the inner cavity S1 of the first lamp cup 710 can be divided into two sub-cavities S11 by the linear partition wall 714, and each sub-cavity S11 accommodates one first light source 410.

[0142] Another example is Figure 7 which shows another exemplary structure of a first lamp cup 710 in an embodiment of the present application, and the first light source 410 is shown by a dotted line. Referring to Figure 7In some alternative embodiments, the inner cavity S1 of the first lamp cup 710 may also accommodate eight first light sources 410, which are arranged in a circular array. Correspondingly, the baffle 714 may be a star-shaped structure, and the inner cavity S1 of the first lamp cup 710 may be divided into eight sub-cavities S11 by the star-shaped baffle 714, each sub-cavity S11 accommodating one first light source 410.

[0143] In other embodiments of this application, the baffle 714 may not be provided in the inner cavity S1 of the first lamp cup 710, thus simplifying the overall structure of the first lamp cup 710. Specifically, Figure 8 An exemplary structure of another first lamp cup 710 in an embodiment of this application is shown. (See reference...) Figure 8 The first lamp cup 710 includes side walls 712 surrounding the bottom wall 711, but does not include retaining walls. The inner cavity S1 is a continuous, undivided, integral space. The inner cavity S1 can accommodate four first light sources 410, wherein there are no physical barriers between any two adjacent first light sources 410, and the light from the multiple first light sources 410 can propagate unobstructed within the inner cavity S1.

[0144] Continue to refer to Figure 3A In some embodiments of this application, the sidewall 712 of the first lamp cup 710 facing the inner cavity S1 is an arc-shaped surface to reflect the light from the first light source 410; however, this is only illustrative. In other embodiments, the sidewall 712 of the first lamp cup 710 facing the inner cavity S1 may also be other types of surfaces, such as a sloping plane. This application does not impose specific limitations on this, as long as the sidewall 712 of the first lamp cup 710 can reflect the light from the first light source 410.

[0145] After introducing the relative arrangement of the first light source 410 and the first lamp cup 710, we will now introduce the relative arrangement of the second light source 420 and the second lamp cup 720.

[0146] Continue to refer to Figure 3A and Figure 3B In some embodiments of this application, the inner cavity S2 of the second lamp cup 720 can be used to accommodate a second light source 420. As mentioned above, the area where the second lamp cup 720 is located is an area with a large light mixing distance. Accommodating a second light source 420 in the second lamp cup 720 can meet the light mixing requirements of the area with a large light mixing distance, and at the same time, it can also avoid the problem of high cost caused by a large number of light sources.

[0147] Continue to refer to Figure 3A and Figure 3BIn some embodiments of this application, the bottom wall 721 of the second lamp cup 720 may have a second through hole 723. The second through hole 723 penetrates the bottom wall 721 of the second lamp cup 720 along the Z direction, thereby connecting the inner cavity S2 of the second lamp cup 720 and the outside of the second lamp cup 720. The second light source 420 may be disposed in the second through hole 723.

[0148] Thus, on the one hand, the second light source 420 can extend into the inner cavity S2 of the second lamp cup 720 through the second through hole 723. The light from the second light source 420 can propagate within the inner cavity S2 of the second lamp cup 720 and exit from the inner cavity S2 of the second lamp cup 720 through the cup rim F2. It can be understood that the cup rim F2 of the second lamp cup 720 and the second through hole 723 are arranged at intervals along the Z direction.

[0149] On the other hand, the second light source 420 can also be connected to other devices outside the second lamp cup 720 via the second through hole 723. For example, in some implementations, the display device 1 may also include a second lamp board 421, which is located on the side of the reflector 70 facing away from the backlight film 60, or in other words, the second lamp board 421, the reflector 70, and the backlight film 60 are arranged sequentially along the Z1 direction. The bottom wall 721 of the second lamp cup 720 of the reflector 70 is disposed on the second lamp board 421. Exemplarily, the bottom wall 721 of the second lamp cup 720 can be connected to the second lamp board 421 by means of adhesion, snap-fit, or fastener connection. The second light source 420 can be connected to the second lamp board 421 via the second through hole 723. The second lamp board 421 can transmit signals to the second light source 420 to control the working state of the second light source 420, such as controlling whether the second light source 420 emits light, controlling the brightness and color of the light emitted by the second light source 420, etc.

[0150] In some implementations, the second through-hole 723 may be located at the geometric center O2 of the bottom wall 721 of the second lamp holder 720. Alternatively, the second through-hole 723 may overlap with the geometric center O2 of the bottom wall 721 of the second lamp holder 720, for example, in... Figure 9A In the illustrated embodiment, the second through-hole 723 is a circular hole, the center of which overlaps with the geometric center O2 of the bottom wall 721 of the second lamp cup 720. Thus, the second light source 420 can be located at the geometric center O2 of the bottom wall 721 of the second lamp cup 720. This makes the overall light path of the second light source 420 within the inner cavity S2 of the second lamp cup 720 more symmetrical, resulting in a better final display effect.

[0151] It is understandable that, depending on the shape of the bottom wall 721 of the second lamp cup 720, the position of the geometric center O2 corresponding to the bottom wall 721 of the second lamp cup 720 can be different. Please refer to the above for details. Figure 3BThe description of the geometric center O1 of the bottom wall 711 of the first lamp cup 710 in the illustrated embodiment will not be repeated here.

[0152] Continue to refer to Figure 3A In some embodiments of this application, the sidewall 722 of the second lamp cup 720 facing the inner cavity S1 is an arc-shaped surface to reflect the light from the second light source 420; however, this is only illustrative. In other embodiments, the sidewall 722 of the second lamp cup 720 facing the inner cavity S1 may also be other types of surfaces, such as a sloping plane. This application does not impose specific limitations on this, as long as the sidewall 722 of the second lamp cup 720 can reflect the light from the second light source 420.

[0153] It should be noted that the above description only schematically illustrates some structural components of the display device 1 and does not constitute a limitation on this application. The display device 1 provided in this application may also include more structural components to achieve different functions, which are illustrated below.

[0154] Continue to refer to Figure 3A In some embodiments of this application, the display device 1 may further include a support plate 80. The support plate 80 and the backlight film 60 are disposed opposite each other along the Z-direction, and the first light source 410, the second light source 420, the first lamp plate 411, the second lamp plate 421, and the reflector 70 are all located between the support plate 80 and the backlight film 60. The support plate 80 can be used to support the first light source 410, the second light source 420, the first lamp plate 411, the second lamp plate 421, and the reflector 70. The support plate 80 can also serve as a reinforcing member to enhance the mechanical strength of the display device 1.

[0155] Among them, Figure 3A In the illustrated embodiment, the four edges of the backlight film 60 can overlap the housing 20 to achieve the installation of the backlight film 60, but this application is not limited to this. In other embodiments, the four edges of the backlight film 60 can also overlap the support plate 80, so that the support plate 80 can support the four edges of the backlight film 60.

[0156] In some implementations, there may be a gap between the backlight film 60 and the reflector 70, that is, the backlight film 60 and the reflector 70 do not contact each other. Based on this, additional support columns can be provided to support the backlight film 60 and prevent the central area of ​​the backlight film 60 from sinking.

[0157] In some other implementations, the backlight film 60 can also contact the reflector 70, which can support the backlight film 60. In this way, there is no need to set up additional support columns to support the backlight film 60, thereby reducing the number of components and making the overall structure of the display device 1 simpler and the assembly efficiency higher.

[0158] Continue to refer to Figure 3A In some embodiments of this application, the support plate 80 may include a first region 810 and a second region 820 arranged along the X direction. Along the Z direction, the first region 810 is disposed opposite to the first lamp holder 710, and the second region 820 is disposed opposite to the second lamp holder 720. In this application, "component A and component B are disposed opposite each other along a certain direction" means that component A and component B are face-to-face in that direction, and the projections of component A and component B along that direction at least partially overlap. Based on this, component A and component B may be spaced apart or closely fitted together in that direction, as will not be elaborated further below.

[0159] Along the Z direction, the first region 810 is closer to the backlight film 60 than the second region 820. In other words, along the Z direction, the distance between the first region 810 and the backlight film 60 is smaller than the distance between the second region 820 and the backlight film 60. This makes the surface of the support plate 80 facing away from the backlight film 60 concave in the first region 810 to accommodate the thinning design of the display device 1.

[0160] For example, in Figure 3A and Figure 3B In the embodiment shown, the first array N1 formed by the first lamp cups 710 can be located in the edge region A3 of the reflector 70. The edge region A3 of the reflector 70 corresponds to the edge region A1 of the display device 1. Accordingly, the first region 810 can be arranged opposite to the edge region A3 of the reflector 70 along the Z direction, so that the first region 810 can be arranged in the edge region A1 of the display device 1.

[0161] Similarly, the second array N2 formed by the second lamp cups 720 can be located in the central region A4 of the reflector 70, which corresponds to the central region A2 of the display device 1. Accordingly, the second region 820 can be arranged opposite to the central region A4 of the reflector 70 along the Z direction, so that the second region 820 can be located in the central region A2 of the display device 1.

[0162] In this way, the reflector 70 and the support plate 80 can be adapted to the thinning design of the display device 1 in the edge area A1, thereby balancing the appearance and cost of the display device 1.

[0163] Continue to refer to Figure 3A In some embodiments of this application, the display device 1 may further include various devices, such as a first device 910 and a second device 920. The first device 910 and the second device 920 may be disposed between the housing 20 and the support plate 80.

[0164] In some implementations, the first device 910 and the second device 920 may be devices such as batteries, chips, circuit boards or sensors, and this application does not impose specific limitations on them.

[0165] Figure 9A This application illustrates another exemplary configuration of the reflector 70 in the display device 1, wherein... Figure 9A Only a portion of the structure in display device 1 is shown. Figure 9B according to Figure 9A A top view of another reflector 70 in an embodiment of this application is shown. Compared to the above... Figure 3A and Figure 3B The display device 1 shown is... Figure 9A and Figure 9B The difference between the display device 1 shown is that the areas that need to be thinned are different in the display device 1. Accordingly, the arrangement of the first lamp cup 710 and the second lamp cup 720 of the reflector 70, and the arrangement of the first area 810 and the second area 820 of the support plate 80 are also different.

[0166] Specifically, refer to Figure 9A and Figure 9B In some feasible solutions, the display device 1 may also include a third device 930 (as an example of a functional device). Compared to other devices such as the first device 910 and the second device 920, the third device 930 has a larger dimension along the Z direction, thus occupying more layout space in the Z direction. To avoid the display device 1 being too large in the Z direction, the stacking area A5 where the third device 930 is located can be designated as an area with a smaller light mixing distance, while other areas outside the stacking area A5 can be designated as areas with a larger light mixing distance. Accordingly, the first lamp cup 710 of the reflector 70 can be disposed in the stacking area A5, and the second lamp cup 720 of the reflector 70 can be disposed in other areas outside the stacking area A5.

[0167] Based on this, in some embodiments of this application, the outer shell 20, the support plate 80 and the reflector 70 are arranged sequentially along the Z1 direction. Furthermore, along the Z direction, the first region 810 of the support plate 80 can be further away from the outer shell 20 than the second region 820 of the support plate 80. That is, the distance between the first region 810 and the outer shell 20 can be greater than the distance between the second region 820 and the outer shell 20, thereby making the surface of the support plate 80 facing the outer shell 20 concave in the first region 810.

[0168] In this way, the third device 930 of the display device 1 can be set at the position corresponding to the first lamp cup 710 of the reflector 70 and the first area 810 of the support plate 80. Both the reflector 70 and the support plate 80 can avoid the third device 930, so the outer shell 20 of the display device 1 can be designed to be relatively flat without local protrusions, which helps to achieve the thinning design of the display device 1 in the stacking area A5.

[0169] Continue to refer to Figure 9A In some implementations, the third device 930 can be disposed between the housing 20 and the first region 810 of the support plate 80. Along the Z-direction, the size of the third device 930 can be larger than the distance between the second region 820 of the support plate 80 and the housing 20. That is, the size of the third device 930 along the Z-direction is larger. Therefore, placing the third device 930 between the housing 20 and the first region 810 of the support plate 80 can absorb the height difference between the third device 930 and other devices such as the first device 910 and the second device 920, thereby avoiding additional increases in the size of the display device 1 along the Z-direction, and thus satisfying the thinning design of the display device 1 in the stacking region A5.

[0170] Meanwhile, the reflector 70 can also work normally to improve the display effect of the display device 1. For example, the display device 1 will not have problems such as uneven light mixing or uneven brightness under large viewing angles, such as side viewing angle.

[0171] For example, Figure 9C according to Figure 9A A schematic diagram of light propagation in reflector 70 according to an embodiment of this application is shown. (Reference) Figure 10 The first light source 410 can emit light, such as light L1. Light L1 can be reflected by the first lamp cup 710 of the reflector 70, and then emitted through the cup opening F1 of the first lamp cup 710 to the outside of the first lamp cup 710. Its specific propagation process is the same as described above. Figure 3C The propagation process of light ray L1 in the illustrated embodiment is essentially the same, therefore the above description can be used as a reference. Figure 3C The relevant descriptions in the illustrated embodiments.

[0172] Similarly, the second light source 420 can emit light, such as light L2. Light L2 can be reflected by the second lamp cup 720 of the reflector 70, and then emitted through the cup opening F2 of the second lamp cup 720 to the outside of the second lamp cup 720. Its specific propagation process is the same as described above. Figure 3C The propagation process of light ray L2 in the illustrated embodiment is essentially the same, therefore it can be referred to the above. Figure 3C The relevant descriptions in the illustrated embodiments.

[0173] Since the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 are coplanar, meaning that the light-emitting surface from which the light L1 is emitted by the first lamp cup 710 and the light-emitting surface from which the light L2 is emitted by the second lamp cup 720 are located on the same plane, there is no height difference between the light-emitting surfaces of the reflector 70 in areas with different mixing distances, and the reflector 70 does not have a sloping transition section. This effectively improves the reflection effect of the reflector 70 on the light L1 from the first light source 410 and the light L2 from the second light source 420, thereby avoiding the aforementioned... Figure 2The solution shown addresses the issue of poor display quality caused by slope variations and height differences. For example, it avoids uneven brightness in display device 1 at wide viewing angles such as side views, effectively improving the display effect of display device 1.

[0174] It is understood that, based on the different orientations of the third device 930 in the display device 1, the orientation of the stacked region A5 in the display device 1 is also different, and correspondingly, the orientation of the first lamp cup 710 is also different. The following is an example description.

[0175] In some of these implementations, the first lamp cup 710 may be located in the left edge region A31 of the reflector 70.

[0176] Specifically, please refer to Figure 9B Multiple first lamp cups 710 can be arranged into a third array N3 along the X and Y directions. The third array N3 is a 2×16 rectangular array. The column direction of the third array N3 can be, for example, the X direction, and the row direction of the third array N3 can be, for example, the Y direction.

[0177] A portion of the multiple second lamp cups 720 can be arranged along the Y direction to form a fourth array N4, and another portion of the multiple second lamp cups 720 can be arranged along both the X and Y directions to form a fifth array N5. The fourth array N4 is a 1×16 rectangular array, and the fifth array N5 is a 17×16 rectangular array. The column direction of the fourth array N4 and the fifth array N5 can be, for example, the X direction, and the row direction of the fourth array N4 and the fifth array N5 can be, for example, the Y direction.

[0178] The fourth array N4, the third array N3, and the fifth array N5 are arranged sequentially along the X1 direction, where the X1 direction is parallel to the X direction. This allows the third array N3 to be positioned in the left edge region A31 of the reflector 70, which means that the first lamp cup 710 is positioned in the left edge region A31 of the reflector 70.

[0179] In some other implementations, the first lamp cup 710 may also be located in the lower edge region A32 of the reflector 70.

[0180] Specifically, Figure 10 This illustration shows another arrangement of the first lamp holder 710 and the second lamp holder 720 in an embodiment of this application. (See reference...) Figure 10 Multiple first lamp cups 710 can be arranged into a sixth array N6 along the X and Y directions. The sixth array N6 is a 16×2 rectangular array. The column direction of the sixth array N6 can be, for example, the X direction, and the row direction of the sixth array N6 can be, for example, the Y direction.

[0181] Multiple second lamp cups 720 can be arranged into a seventh array N7 along the X and Y directions. The seventh array N7 is a 16×5 rectangular array. The column direction of the seventh array N7 can be, for example, the X direction, and the row direction of the seventh array N7 can be, for example, the Y direction.

[0182] The sixth array N6 and the seventh array N7 are arranged along the Y direction, so that the sixth array N6 is located in the lower edge region A32 of the reflector 70, that is, the first lamp cup 710 is located in the lower edge region A32 of the reflector 70.

[0183] In some of these implementations, the first lamp cup 710 may also be positioned at the centerline of the reflector 70 along the Y direction.

[0184] Specifically, Figure 11A and Figure 11B This illustration shows another arrangement of the first lamp cup 710 and the second lamp cup 720 in an embodiment of this application, wherein... Figure 11A This is a top view of reflector 70. Figure 11B For the reflector 70 in Figure 11A A partial side view of area A6 in the center. (Reference) Figure 11A and Figure 11B Multiple first lamp cups 710 can be arranged into an eighth array N8 along the X and Y directions. The eighth array N8 is a 2×16 rectangular array. The column direction of the eighth array N8 can be, for example, the X direction, and the row direction of the eighth array N8 can be, for example, the Y direction.

[0185] A portion of the second lamp cup 720 can be arranged into a ninth array N9 along the X and Y directions, and another portion of the second lamp cup 720 can be arranged into a tenth array N10 along the X and Y directions. Both the ninth array N9 and the tenth array N10 are 17×16 rectangular arrays. The column direction of the ninth array N9 and the tenth array N10 can be, for example, the X direction, and the row direction of the ninth array N9 and the tenth array N10 can be, for example, the Y direction.

[0186] The ninth array N9, the eighth array N8, and the tenth array N10 are arranged sequentially along the X1 direction, so that the eighth array N8 is located at the center line of the reflector 70 along the Y direction, that is, the first lamp cup 710 is located at the center line of the reflector 70 along the Y direction.

[0187] Apart from this, the other structures and deformations of the reflector 70 in the scenario where the stacked region A5 is thinned are essentially the same as those of the reflector 70 in the scenario where the edge region A1 is thinned.

[0188] For example, the specific structure and deformation of the first lamp cup 710 in the scenario where the stacked region A5 is thinned are substantially the same as those of the first lamp cup 710 in the scenario where the edge region A1 is thinned.

[0189] For example, in Figures 9A to 11B In the illustrated embodiment, the first lamp holder 710 may also include a first through hole 713, and the first light source 410 may be disposed in the first through hole 713, as detailed above. Figure 3A and Figure 3B Description of the first through hole 713 in the illustrated embodiment.

[0190] For example, in Figures 9A to 11B In the illustrated embodiment, the first lamp cup 710 may also include a baffle 714, which can divide the inner cavity S1 of the first lamp cup 710 into multiple sub-cavities S11, as detailed above. Figures 3A to 7 Description of retaining wall 714 in the illustrated embodiment.

[0191] For example, in some other embodiments, the first lamp cup 710 may not include the baffle 714. Specifically, Figure 12A and Figure 12B This application illustrates an exemplary structure of another first lamp cup 710 in an embodiment of the present application, wherein, Figure 12A This is a top view of reflector 70. Figure 12B For the reflector 70 in Figure 12A A partial side view of area A7 in the center. (Reference) Figure 12A and Figure 12B The arrangement of the first lamp cup 710 and the second lamp cup 720 is the same as Figure 11A and Figure 11B The arrangement methods in the illustrated embodiments are essentially the same, therefore they can be referred to. Figure 11A and Figure 11B The relevant descriptions in the illustrated embodiments will not be repeated here. Among them, [the following is a list of related concepts]. Figure 11A and Figure 11B compared to, Figure 12A and Figure 12B The difference lies in that the first lamp cup 710 does not include the retaining wall, and the inner cavity S1 of the first lamp cup 710 is a continuous, undivided whole space, as detailed above. Figure 8 Description of the first lamp cup 710 in the illustrated embodiment.

[0192] The other structures and deformations of the second lamp cup 720 in the scenario where the stacked region A5 is thinned are essentially the same as those of the second lamp cup 720 in the scenario where the edge region A1 is thinned.

[0193] For example, in Figures 9A to 12B In the illustrated embodiment, the second lamp holder 720 may also include a second through hole 723, and the second light source 420 may be disposed in the second through hole 723. For details, please refer to the above description. Figure 3A and Figure 3B Description of the second through hole 723 in the illustrated embodiment.

[0194] For example, in Figures 9A to 12B In the illustrated embodiment, the cup rim F2 of the second lamp cup 720 and the cup rim F1 of the first lamp cup 710 can have the same shape and size. For example, the cup rim F2 of the second lamp cup 720 and the cup rim F1 of the first lamp cup 710 can both be squares, and the side length a2 of the cup rim F2 of the second lamp cup 720 is the same as the side length a1 of the cup rim F1 of the first lamp cup 710. See the above for details. Figure 3B and Figure 3C Description of the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 in the illustrated embodiment.

[0195] In summary, for the other structures and deformations of the reflector 70 in the scenario where the stacked region A5 is thinned, please refer to the relevant description of the reflector 70 in the scenario where the edge region A1 is thinned, and they will not be repeated here.

[0196] Based on the above Figures 3A to 12B In addition to the reflector 70 shown in the embodiment, this application also provides a backlight module that can be applied to the above-mentioned... Figures 3A to 12B In any of the display devices 1 shown in the embodiments, the backlight module is used to realize the display function of the display device 1. The following is an exemplary description in conjunction with the accompanying drawings.

[0197] Specifically, Figure 13 An exemplary structure of a backlight module 2 according to an embodiment of this application is shown. (Reference) Figure 13 The backlight module 2 may include a first light source 410, a second light source 420, a first lamp panel 411, a second lamp panel 421, a reflector 70, and a support plate 80. The specific structure, deformation, function, and arrangement of the first light source 410, the second light source 420, the first lamp panel 411, the second lamp panel 421, the reflector 70, and the support plate 80 are as described above. Figures 3A to 12B The first light source 410, the second light source 420, the first lamp panel 411, the second lamp panel 421, the reflector 70, and the support plate 80 in the display device 1 shown are essentially the same, therefore, the above description can be used as a reference. Figures 3A to 12B The relevant descriptions of the embodiments shown are briefly introduced below with reference to the accompanying drawings.

[0198] Continue to refer to Figure 13 Along the Z direction, the first light source 410 and the second light source 420 are respectively positioned opposite to different areas of the backlight film 60, and the first light source 410 is closer to the backlight film 60 than the second light source 420.

[0199] The first light source 410 is housed in the inner cavity S1 of the first lamp cup 710 of the reflector 70, and the first lamp cup 710 can reflect the light from the first light source 410 to the backlight film 60.

[0200] The first lamp plate 411 is located on the side of the reflector 70 facing away from the backlight film 60. The bottom wall 711 of the first lamp cup 710 is provided on the first lamp plate 411. A first through hole 713 is provided on the bottom wall 711 of the first lamp cup 710. Figure 14 An exemplary structure of the first through-hole 713 in an embodiment of this application is shown. (Reference) Figure 14 and combined Figure 13 The first through hole 713 extends along the Z-direction through the bottom wall 711 of the first lamp cup 710. The first light source 410 can be disposed in the first through hole 713 and connected to the first lamp board 411 via the first through hole 713. The first lamp board 411 can transmit signals to the first light source 410 to control the working state of the first light source 410, such as controlling whether the first light source 410 emits light, controlling the brightness and color of the light emitted by the first light source 410, etc.

[0201] The second light source 420 is housed in the cavity S2 of the second lamp cup 720 of the reflector 70, and the second lamp cup 720 can reflect the light from the second light source 420 to the backlight film 60.

[0202] The second lamp plate 421 is located on the side of the reflector 70 facing away from the backlight film 60, and the bottom wall 721 of the second lamp cup 720 is disposed on the second lamp plate 421. (Reference) Figure 14 and combined Figure 13 A second through hole 723 is provided on the bottom wall 721 of the second lamp cup 720, and the second through hole 723 penetrates the bottom wall 721 of the second lamp cup 720 along the Z direction. The second light source 420 can be disposed in the second through hole 723 and connected to the second lamp plate 421 through the second through hole 723. The second lamp plate 421 can transmit signals to the second light source 420 to control the working state of the second light source 420, such as controlling whether the second light source 420 emits light, controlling the brightness and color of the light emitted by the second light source 420, etc.

[0203] The support plate 80 and the backlight film 60 are arranged opposite each other along the Z direction. The first light source 410, the second light source 420, the first lamp board 411, the second lamp board 421, and the reflector 70 are respectively disposed between the support plate 80 and the backlight film 60. The support plate 80 can be used to support the first light source 410, the second light source 420, the first lamp board 411, the second lamp board 421, the backlight film 60, and the reflector 70.

[0204] In the aforementioned backlight module 2, since the cup height H1 of the first lamp cup 710 is smaller than the cup height H2 of the second lamp cup 720, the first lamp cup 710 can be placed in the area of ​​the backlight module 2 with a smaller light mixing distance, that is, in the area of ​​the backlight module 2 that needs to be thinned; the second lamp cup 720 can be placed in the area of ​​the backlight module 2 with a larger light mixing distance, that is, in the area of ​​the backlight module 2 that does not need to be thinned. In this way, the reflector 70 can adapt to the localized thinning design of the backlight module 2, balancing the appearance and cost of the display device in which the backlight module 2 is located.

[0205] Secondly, the cup rim surface F1 of the first lamp cup 710 and the cup rim surface F2 of the second lamp cup 720 are coplanar, compared to the above. Figure 2 In the illustrated scheme, the light-emitting surfaces of the reflector 50 and reflector 70 in regions with different light mixing distances are on the same plane, with no height difference between the light-emitting surfaces, and the reflector 70 does not have a sloping transition section. Therefore, the aforementioned issues can be avoided. Figure 2 The solution shown can avoid the problem of poor display effect caused by slope changes and height differences. For example, it can avoid the problem of uneven brightness in the display device where the backlight module 2 is located under large viewing angles such as side viewing angle.

[0206] Continue to refer to Figure 13 In some embodiments of this application, the four edges of the backlight film 60 can overlap the support plate 80 to achieve the installation of the backlight film 60.

[0207] In some of these implementations, such as Figure 13 As shown, there may be a gap between the backlight film 60 and the reflector 70, that is, the backlight film 60 and the reflector 70 do not contact each other. Based on this, additional support columns can be provided to support the backlight film 60 and prevent the central area of ​​the backlight film 60 from sinking.

[0208] In some other implementations, the backlight film 60 can also contact the reflector 70, which can support the backlight film 60. In this way, there is no need to set up additional support columns to support the backlight film 60, thereby reducing the number of components and making the overall structure of the backlight module 2 simpler and the assembly efficiency higher.

[0209] In addition, the other structures and variations of the backlight module 2 described above are similar to those described above. Figures 3A to 12B The display device 1 in the illustrated embodiment is substantially the same.

[0210] For example, the reflector 70 of the backlight module 2 described above is the same as the aforementioned Figures 3A to 12B The reflector 70 of the display device 1 in the illustrated embodiment is substantially the same.

[0211] For example, the support plate 80 of the backlight module 2 mentioned above and the aforementioned Figures 3A to 12B The support plate 80 of the display device 1 in the illustrated embodiment is substantially the same.

[0212] For example, the support plate 80 of the backlight module 2 may also include a first region 810 and a second region 820 arranged along the X direction. Along the Z direction, the first region 810 is disposed opposite to the first lamp cup 710 of the reflector 70, and the second region 820 is disposed opposite to the second lamp cup 720 of the reflector 70. Furthermore, the first region 810 is closer to the backlight film 60 than the second region 820, thereby allowing the support plate 80 to adapt to the thinning design of the display device 1.

[0213] The backlight module 2 provided in this application can be locally thinned in any area to meet the thinning requirements of the display device in which the backlight module 2 is located. Depending on the area in the backlight module 2 that needs to be thinned, the arrangement of the first lamp cup 710 and the second lamp cup 720 in the reflector 70 can also be different. Correspondingly, the arrangement of the first region 810 and the second region 820 of the support plate 80 can also be different. The following description, in conjunction with the accompanying drawings, provides an example.

[0214] Continue to refer to Figure 13 and combined Figure 3A and Figure 3B In some feasible solutions, the display device 1 can be thinned in the edge region A1. Based on this, the first array N1 of the first lamp cups 710 can be located in the edge region A3 of the reflector 70, and correspondingly, the first region 810 of the support plate 80 and the edge region A3 of the reflector 70 are positioned opposite each other along the Z direction; the second array N2 of the second lamp cups 720 can be located in the central region A4 of the reflector 70, and correspondingly, the second region 820 of the support plate 80 and the central region A4 of the reflector 70 are positioned opposite each other along the Z direction. This satisfies the thinning requirement of the display device 1 in the edge region A1. For details, please refer to the above. Figure 3A and Figure 3B The descriptions of the reflector 70 and the support plate 80 in the illustrated embodiment will not be repeated here.

[0215] Figure 15 This illustration shows an exemplary structure of another backlight module 2 in an embodiment of this application. Compared to the above... Figure 13 The backlight module 2 shown is shown. Figure 15 The difference between the backlight module 2 shown is that the areas that need to be thinned are different in the backlight module 2. Accordingly, the arrangement of the first lamp cup 710 and the second lamp cup 720 of the reflector 70, and the arrangement of the first area 810 and the second area 820 of the support plate 80 are also different.

[0216] Specifically, refer to Figure 15 and combined Figure 9A and Figure 9B In other feasible solutions, the display device 1 can be thinned in the stacking region A5 where the third device 930 is located. Accordingly, the first lamp cup 710 and the first region 810 of the support plate 80 can be located in the stacking region A5; the second lamp cup 720 and the second region 820 of the support plate 80 can be located in other regions besides the stacking region A5. In this way, the thinning requirement of the display device 1 in the stacking region A5 can be met. For details, please refer to the above. Figure 9A and Figure 9B The descriptions of the reflector 70 and the support plate 80 in the illustrated embodiment will not be repeated here.
