Description

Technical Field

[0001] The present application relates to the technical field of display devices, and in particular to a display device and a middle frame structure that can be used in the display device. Background Art

[0002] In the field of liquid crystal display technology, light mixing distance is a key parameter that determines the display quality. Figure 1 The figure shows a partial structure of an existing display device, where the light source 30 is fixed on the bearing surface M of the back plate 10 , and the light mixing distance d is the distance between the bearing surface M and the optical diffuser 20 .

[0003] The light mixing distances of different display models on the market generally vary. For example, high-end products have shorter distances, while low-end products have longer distances. When the overall device structure is the same but the light mixing distances differ, re-molding the structural components can be used to achieve this. However, for example, if the light mixing distance is longer, the size of the re-molded structural components will be significantly larger, causing the structural components to occupy a larger space within the display device. Utility Model Content

[0004] This application provides a display device and a mid-frame structure that can be used in the display device. The main purpose is to provide a combination of backplanes and mid-frames that not only accommodates a variety of different light mixing distances but also allows the re-molded mid-frame structure to be smaller in size, thus minimizing space occupation and reducing manufacturing costs.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, the present application provides a display device, which may be a television, a tablet computer (pad), a notebook computer, an ultra-mobile personal computer (UMPC), etc.

[0007] The display device includes a middle frame structure and a back panel, the middle frame structure is arranged at the edge of the back panel, and the back panel is connected to the middle frame structure; the display device also includes a light source, a light diffusion structure and a reflector, the light source is arranged on the back panel, and the light diffusion structure is arranged on the light output side of the light source; a first support plate is arranged on the inner side of the middle frame structure; the back panel, the first support plate and the light diffusion structure are arranged in sequence in a first direction, the first direction is the thickness direction of the display device, and the light diffusion structure is connected to the first support plate; wherein the first support plate includes a first part and a second part, the second part extends in a direction away from the light diffusion structure, and the second part fixes the reflector; and the first support plate is not connected to the back panel.

[0008] In the display device provided in the present application, the middle frame structure includes a first support plate, the light diffusion structure is connected to the first support plate, and the light source is fixed on the back plate. It can be understood that the light source and the light diffusion structure are arranged on different structural members, the light source is arranged on the back plate, and the light diffusion structure is arranged on the middle frame structure. In addition, the first support plate is not connected to the back plate, that is, the middle frame structure is decoupled from the back plate; in this way, in order to configure a display device with different light mixing distances, the back plate does not need to be replaced, but the middle frame structure needs to be changed, the setting position of the first support plate needs to be changed, and the light mixing distance needs to be changed. Thus, the back plate can be compatible with a variety of different light mixing distances.

[0009] In addition, the present application uses a bent, simple-structured first support plate as a carrier of the light diffusion structure and the reflector. When the light mixing distance is large, the inclination angle of the second part can be changed, and the simple-structured first support plate basically does not occupy a large space.

[0010] In one achievable manner, an accommodating space is provided between the first support plate and the back plate, and the accommodating space is used to provide a light mixing distance of the display device.

[0011] There is a accommodating space between the first support plate and the back plate of the present application, and the accommodating space is used to provide a light mixing distance for the display device. That is to say, in order to configure a display device with a different light mixing distance, the back plate does not need to be replaced, but the middle frame needs to be changed, and the setting position of the first support plate needs to be changed, thereby changing the accommodating space and the light mixing distance. In this way, the back plate can be compatible with a variety of different light mixing distances.

[0012] In one achievable manner, the light diffusion structure is connected to the first portion, and the distance between the light diffusion structure and the back plate is a light mixing distance of the display device.

[0014] In one possible implementation, one end of the second part is connected to the first part, and the other end is suspended.

[0015] This can be understood as follows: the second part has a fixed end and a free-hanging end. The fixed end is connected to the first part, while the free-hanging end is suspended in the air and not connected to other structural components. In some manufacturing processes, this can reduce the difficulty of manufacturing the midframe. In addition, when the light mixing distance is changed, the tilt angle of the second part can be changed, eliminating the need for additional requirements for structural component mold opening, thereby simplifying the manufacturing process and reducing manufacturing costs.

In addition, in this example, the end of the second part of the first support plate away from the first part is not connected to the second support plate, that is, the first support plate and the second support plate are separated from each other and are not connected together through the second part. In this way, when the mixing distance changes, the inclination angle of the second part can be changed, and there is no need to make more requirements for the mold opening of the structural parts, which can simplify the preparation process and reduce manufacturing costs.

[0020] In one achievable manner, the end of the first part away from the second part is connected to the inner side of the middle frame structure; the second support plate is connected to the inner side of the middle frame structure; and the back plate is arranged between the first support plate and the second support plate.

[0087] Before introducing the embodiments of this application, Figure 2 The technical term "light mixing distance" involved in this application is explained.

[0088] like Figure 2 As shown, after the light emitted by the light source 30 is transmitted to the diffuser 20, the diffuser 20 can diffuse the light, making the light emitted from the diffuser 20 more uniform and providing a better visual effect. In some optional embodiments, the distance d1 between the light source 30 and the diffuser 20 can be referred to as the light mixing distance. In other optional embodiments, the light source 30 is disposed on the back panel 10. In some scenarios in this field, since the light source 30 is relatively small and can be ignored, the distance d2 between the back panel 10 and the diffuser 20 can also be referred to as the light mixing distance.

[0089] The following embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0090] The present invention provides a display device, which may be a television, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA), a tablet computer (pad), a notebook computer, or a vehicle-mounted mobile electronic device. The present invention does not impose any particular restrictions on the specific form of the display device.

[0091] Figure 3As an example, a structural diagram of a display device 100 is provided, in which the display device 100 includes a middle frame structure 101, and a display screen 102 is mounted on the middle frame structure 101. The display screen 102 here can be a liquid crystal display (LCD) panel or a self-luminous display screen. When the display screen 102 is a self-luminous display screen, the display screen 102 can be, for example, an organic light-emitting diode (OLED) display screen or a quantum dot light-emitting diode (QLED) display screen. When the display screen 102 is a liquid crystal display screen, the display device 100 can be referred to as a liquid crystal display device; when the display screen 102 is a self-luminous display screen, the display device 100 can be referred to as a self-luminous display device.

[0092] Regardless of whether the display screen 102 is a liquid crystal display screen or a self-luminous display screen, the display screen 102 includes a display area. The display area includes a plurality of sub-pixels, which may include, for example, red (R) sub-pixels, green (G) sub-pixels, and blue (B) sub-pixels.

[0093] Figure 4 This is an exploded schematic diagram of a display device 100 according to an embodiment of the present application. In addition to a midframe structure 101 and a display screen 102, the display device 100 may also include a back panel 104 and a rear cover 103. The display screen 102 and the rear cover 103 are disposed on opposite sides of the midframe structure 101. The back panel 104 serves as the skeleton and carrier of the entire display device, and can accommodate most of the display device's structural components and electronic devices, such as a controller, processor, field output integrated circuit, switching power supply module, speaker, cathode ray tube, and other functional components.

[0094] In some display devices, the light source and the light diffusion structure are both arranged on the back panel 104 . This can be understood as follows: the back panel has a depth in the arrangement direction of the light source and the light diffusion structure, and this depth determines the light mixing distance of the display device.

[0095] If you need to change the light mixing distance or the thickness of the entire device, you will need to replace the back panel. For example, if you need to reduce the light mixing distance, you will need to replace the back panel with a smaller depth. If you need to increase the light mixing distance, you will need to replace the back panel with a larger depth.

[0096] In the feasible manufacturing process, the manufacturing cost of the backplane is relatively high. If the backplane mold needs to be replaced in order to change the light mixing distance or adapt to different device thicknesses, this will significantly increase the manufacturing cost of the display device.

[0097] In order to make the backplane compatible with a variety of solutions with different light mixing distances and reduce manufacturing costs, this application provides some achievable structures, which are detailed below.

[0098] like Figure 5 、 Figure 6 and Figure 7 , Figure 5 1 is an assembly diagram of the back plate 104 and the middle frame structure 101 provided in an embodiment of the present application. Figure 6 yes Figure 5 The exploded view of the back plate 104 and the middle frame structure 101 in FIG. Figure 7 It is along Figure 5 Part of the cross-sectional view of Q1-Q1.

[0099] The display device of the present application example includes a middle frame structure 101, such as Figure 6 A accommodating cavity 101A is formed in the middle frame structure 101, and the back plate 104 is arranged in the accommodating cavity 101A. The back plate 104 is connected to the middle frame structure 101. It can be understood that the middle frame structure 101 is arranged at the edge of the back plate 104, and the middle frame structure 104 can be arranged around the periphery of the back plate 104.

[0100] like Figure 7 The display device further includes a light source 105, a light diffusion structure 106, and a display screen 102. The light source 105 is disposed on the back panel 104, the light diffusion structure 106 is located on the light-emitting side of the light source 105, and the display screen 102 is located on the light-emitting side of the light diffusion structure 106. The light diffusion structure 106 is configured to receive light emitted by the light source 105 and diffuse the light emitted by the light source 105 so that the light is projected more evenly onto the display screen 102, thereby improving the display effect.

[0101] For example, in Figure 7 In the embodiment, the light source 105, the light diffusion structure 106 and the display screen 102 are arranged along the Z direction. Figure 4 in the thickness direction of the display device.

[0102] The light diffusion structure 106 of the present application example is installed on the middle frame structure 101. For example, Figure 7 In this example, the middle frame structure 101 may include a first support plate 1012, the first support plate 1012 is located on the inner side of the middle frame structure 101, and the light diffusion structure 106 may be provided on the first support plate 1012. The back plate 104, the first support plate 1012 and the light diffusion structure 106 may be arranged along a first direction (eg Figure 7The first direction may be the thickness direction of the display device.

[0103] exist Figure 7 In FIG. 1 , the distance between the back plate 104 and the light diffusion structure 106 can be regarded as the light mixing distance d1 of the display device.

[0104] It can be understood in this way: the light source 105 of the example of this application is set on the back panel 104, and the light diffusion structure 106 is not set on the back panel 104, but the light diffusion structure 106 is set on the middle frame structure 101, for example, on the first support plate 1012 of the middle frame structure 101.

[0105] See Figure 7 and Figure 8 , Figure 7 and Figure 8 The difference lies in the different mixing distances. Figure 7 and Figure 8 , change the mixing distance from Figure 7 The d1 increases to Figure 8 When d2 is obtained, only the middle frame structure 101 needs to be replaced. It can also be considered that another middle frame structure 101 needs to be re-molded and designed, and the back panel 104 does not need to be replaced, so that the back panel 104 can be compatible with display device products with different configurations. In this way, when designing products with different configurations, only the middle frame structure 101 needs to be changed, and the back panel 104 does not need to be changed to achieve compatibility with different mixing distances. The development time of products with different configurations can also be shortened, and the manufacturing cost can be correspondingly reduced.

[0106] In some optional middle frame structures, such as Figure 9 As shown, the middle frame structure 101 may include a first mounting surface and a second mounting surface, and the first mounting surface and the second mounting surface are arranged along the thickness direction of the display device, such as along Figure 8 The first mounting surface is used to fix the back plate 104 including the light source 105, and the second mounting surface is used to fix the light diffusion structure 106. The distance between the first mounting surface and the second mounting surface can be regarded as the light mixing distance of the display device. When the light mixing distance of the display device needs to be changed, the middle frame structure can be replaced to change the distance between the first mounting surface and the second mounting surface. For example, when the light mixing distance needs to be reduced, Figure 9 (A) shows that S1 is reduced to Figure 9 (B) S2 shown, without the need to replace Figure 7 and Figure 8 The back panel 104. Therefore, on the basis of changing the light mixing distance and adapting to different models, the manufacturing cost can also be reduced.

[0107] In some display devices, after the light emitted from the light source 105 is projected onto the light diffusion structure 106, the light in the center of the light diffusion structure 106 is stronger than the light in the edge area, such as Figure 7 As shown, the edge region Q of the light diffusion structure 106 may receive weaker light, which ultimately makes the light of the entire display screen 102 uneven, and the display effect of the edge region of the display screen 102 is poor, which reduces the user experience.

[0108] In order to alleviate the unevenness, Figure 7 and Figure 8 As shown, the display device may further include a reflector 107, which may be used to reflect light from the light source 105 to the edge area of ​​the light diffusion structure 106, thereby enhancing the light intensity in the edge area of ​​the display screen 102 and optimizing the display effect.

[0109] In some optional structures, the reflective member 107 may include reflective paper, or may be other reflective structures.

[0110] See Figure 7 and Figure 8 A portion of the reflector 107 is disposed on the back plate 104 . For example, a first reflective portion 1071 of the reflector 107 is disposed on the surface of the back plate 104 for mounting the light source 105 .

[0111] A plurality of light sources 105 may be integrated on the back panel 104 , and these light sources 105 may be arranged in an array on the back panel 104 . The area where the plurality of light sources 105 are arranged may be regarded as a light source integration area, and the first reflective portion 1071 of the reflector 107 may be arranged along the periphery of the light source integration area.

[0112] The reflector 107 may further include a second reflective portion 1072 connected to the first reflective portion 1071, the second reflective portion 1072 extending toward the edge region of the light diffusion structure 106, and being configured to reflect more light emitted by the light source 105 toward the edge region of the light diffusion structure 106. Figure 7 and Figure 8 The dashed line with arrows shows that the second reflective portion 1072 reflects light toward the edge region of the light diffusion structure 106 .

[0113] In some structures, the second reflective portion 1072 can be arranged along the periphery of the light source integrated area to form an enclosing cavity, thereby enclosing multiple light sources 105 in the enclosing cavity. In this way, the light emitted by the light source 105 is projected onto the second reflective portion 1072 of the reflective element 107. The second reflective portion 1072 arranged along the periphery of the light source integrated area can reflect more light onto the light diffusion structure 106.

[0114] In some examples, such as Figure 7 and Figure 8 The reflector 107 may further include a third reflective portion 1073, which is connected to the second reflective portion 1072 and may be fixed to the middle frame structure 101. By fixing the first reflective portion 1071 to the back plate 104 and fixing the third reflective portion 1073 to the middle frame structure 101, the installation reliability and stability of the reflector 107 may be improved.

[0115] In order to fix the reflector 107, as Figure 7 and Figure 8 , the first support plate 1012 may include a first portion 1012A and a second portion 1012B.

[0116] The first portion 1012A is connected to the middle frame structure 101. In some examples, the first portion 1012A can fix the light diffusion structure 106. For example, an adhesive can be used to fix the light diffusion structure 106 to the first portion 1012A. The third reflective portion 1073 of the reflector 107 can be fixed to the first portion 1012A.

[0117] like Figure 7 and Figure 8 In the first support plate 1012, the second portion 1012B extends in a direction away from the light diffusion structure 106. It can be understood that the second portion 1012B extends in a direction toward the light source 105. The second portion 1012B fixes at least a portion of the second reflective portion 1072 of the reflector 107. For example, Figure 7 and Figure 8 In the embodiment, part of the second reflecting portion 1072 is fixed on the second portion 1012B.

[0118] In some display devices, such as Figure 7 and Figure 8 The second portion 1012B for fixing the second reflective portion 1072 is tilted so that it can effectively receive light from the light source 105 and reflect more light to the edge area of ​​the light diffusion structure 106 .

[0119] The tilt angle of the second portion 1012B is related to the light mixing distance of the display device. For example, Figure 7 When the light mixing distance is d1, the tilt angle of the second portion 1012B is X1. When the light mixing distance increases to Figure 8 At d2 shown, the tilt angle of the second portion 1012B is X2, which is smaller than the tilt angle X1. In this way, when the light mixing distance of the display device increases, the tilt angle becomes smaller.

[0120] In some technologies, a support platform can be set on the middle frame structure, and the support platform has two opposite support surfaces, one of which is used to fix the light diffusion structure, and the other is used to fix the back panel. The surface connecting the two support surfaces can be set as an inclined surface, which can be used to fix the reflector. If the mixing distance of the display device is large, for example, when the mixing distance is greater than or equal to 15 mm, the inclination angle of the inclined surface connecting the two support surfaces is small, which will make the size of the entire support platform larger and occupy more space.

[0121] However, the example of this application Figure 7 and Figure 8 In the embodiment, the first portion 1012A of the first support plate 1012 supports the light diffusion structure 106, and the second portion 1012B is tilted to support the reflector 107. Furthermore, the first support plate 1012 is not connected to the back plate 104. This can be understood as: the back plate 104 is decoupled from the first support plate 1012, and the back plate 104 is not connected to the first support plate 1012.

[0122] The first support plate 1012 has a simple structure. When the light mixing distance changes, only the position of the first support plate 1012 and the tilt angle of the second portion 1012B of the second support plate 1012 need to be adjusted to accommodate display devices of varying thicknesses. This prevents the first support plate 1012 from becoming structurally complex or bulky due to changes in the light mixing distance, such as a larger light mixing distance.

[0123] In addition, the first support plate 1012 is not connected to the back plate 104 and is decoupled. In this way, the back plate 104 can be decoupled from the position and volume of the first support plate 1012, making the design of the first support plate 1012 more flexible. For example, the volume will not be larger due to the constraints of the mixing distance.

[0124] like Figure 7 and Figure 8 As shown, a housing space 1011 is defined between the first support plate 1012 and the back plate 104. The housing space 1011 is used to provide a light mixing distance for the display device. The housing space 1011 may include a portion of the light mixing distance or the entire light mixing distance. In other words, the entire light mixing distance falls within the housing space 1011, or only a portion of the light mixing distance falls within the housing space 1011.

[0125] See Figure 7 and Figure 8 The light diffusion structure 106 is connected to the first portion 1012A, and the distance between the light diffusion structure 106 and the back plate 104 is the light mixing distance of the display device.

[0126] like Figure 9As shown, in the example middle frame structure 101 of the present application, one end of the second portion 1012B of the first support plate 1012 is connected to the first portion 1012A, while the other end is suspended. That is, the second portion 1012B includes a connecting end and a free end. The connecting end is connected to the first portion 1012A, while the free end is suspended and not connected to other structural components. For example, the free end of the second portion 1012B is not connected to a structural component of the supporting back plate 104.

[0127] The end of the second portion 1012B of the first support plate 1012 provided in the present application is suspended and not connected to other structural parts. From the perspective of the manufacturing process, the manufacturing process of the first support plate 1012 can be simplified and the manufacturing cost can be reduced.

[0128] In some examples, the first portion 1012A can be connected to the second portion 1012B via a connection structure, such as a colloid connection. In other examples, the first portion 1012A and the second portion 1012B are integrally structured, that is, the first support plate 1012 is an integrally molded structural member, such as one-piece molded by injection molding.

[0129] like Figure 10 In this example, a first support plate 1012 is disposed inside the middle frame structure, and a second support plate 1013 may also be disposed inside the middle frame structure. The second support plate 1013 is located on a side of the back plate 104 away from the first support plate 1012; a portion of the back plate 104 is located between the second support plate 1013 and the first support plate 1012. In this example, the second support plate 1013 can be used to secure the back plate 104.

[0130] exist Figure 10 In this example, the free end of the second portion 1012B of the first support plate 1012 is not connected to the second support plate 1013. This means that the second support plate 1013, which is used to secure the back plate 104, is decoupled from the first support plate 1012, which is used to secure the light diffusion structure 106. The two support plates are independent of each other. This increases the design freedom of the two plates, eliminating mutual constraints and interdependence.

[0131] See Figure 10 A third support plate 1014 is also provided on the inner side of the middle frame structure 101. The third support plate 1014 is located between the first support plate 1012 and the second support plate 1013. An installation cavity 1015 is formed between the second support plate 1013 and the third support plate 1014. The edge portion of the back plate 104 is located in the installation cavity 1015.

[0132] By using the second support plate 1013 and the third support plate 1014 that are arranged opposite to each other, the edge of the back plate 104 can be clamped in the installation cavity 1015 between the two support plates, thereby improving the installation reliability and stability of the back plate 104.

[0133] In some examples, in order to facilitate the fixed installation of the back plate 104, as shown in FIG. Figure 10 One end of the third support plate 1014 is connected to the inner side of the middle frame structure, and the other end extends in a direction away from the second support plate 1013. In this way, the opening of the installation cavity 1015 can be enlarged, which facilitates the insertion of the back plate 104 and improves assembly efficiency.

[0134] Continue reading Figure 10 A fourth support plate 1016 may be further provided on the inner side of the middle frame structure. The fourth support plate 1016 is provided on a side of the first support plate 1012 away from the third support plate 1014. The display screen 102 may be connected to the fourth support plate 1016.

[0135] In addition, the fourth support plate 1016 is disposed opposite to the first support plate 1012 , and the edge of the light diffusion structure 106 can be clamped between the first support plate 1012 and the fourth support plate 1016 , thereby improving the installation reliability and stability of the light diffusion structure 106 .

[0136] like Figure 11 , Figure 11 This is a partial structure of a backplate 104 in an example of this application. The backplate 104 includes a first section 1041, a bent section 1043, and a second section 1042. The bent section 1043 connects the first section 1041 and the second section 1042. The second section 1042 is further away from the light diffusion structure 106 than the first section 1041. In other words, the bent section 1043 bends away from the light diffusion structure 106.

[0137] In some examples, the second section 1042 can be used to support some structural components or electronic devices in the display device, for example, a controller, a processor, a field output integrated block, a switching power supply block, and a speaker functional device can be installed.

[0138] By adopting the bent section 1043 , the strength of the back plate 104 can be increased, thereby improving the reliability of the back plate.

[0139] In order to further increase the strength of the back plate, the Figure 10 and Figure 11 The edge portion of the back plate 104 includes a bent portion. For example, the first section 1041 of the back plate includes a bent portion, and the bent portion can be bent at 180°.

[0140] In some processes, a tolerance may be allowed for the bending angle of the bent portion. For example, the bent portion may be bent at 170° to 180°.

[0141] Figure 12 This is a structural diagram of a backplane 104 provided in an embodiment of the present application. Figure 13 yes Figure 12 A magnified image of point A, Figure 14 yes Figure 12 The enlarged view of point B, Figure 15 yes Figure 13 Q2-Q2 cross-section diagram.

[0142] In order to improve the strength of the back plate 104, as Figure 13 and Figure 14 At least one reinforcing rib 1044 may be provided on the back plate 104 . For example, a plurality of reinforcing ribs 1044 may be provided. The plurality of reinforcing ribs 1044 may be arranged at intervals on the back plate 104 .

[0143] For example, Figure 13 In the Y-extension direction of the back plate 104 , a plurality of reinforcing ribs 1044 are arranged at intervals along the Y-extension direction.

[0144] For another example, Figure 14 In the X-extension direction of the back plate 104 , a plurality of reinforcing ribs 1044 are arranged at intervals along the X-extension direction.

[0145] There are many ways to realize the location of the reinforcing rib 1044 on the back plate. Figure 15 In the embodiment, the reinforcing rib 1044 can be set at a position of the second section 1042 of the back plate close to the bending section 1043 to further improve the mechanical strength of the back plate 104.

[0146] In this application example, Figure 16 As shown, Figure 16 The diagram shows the connection between the back plate 104 and the midframe structure. The second support plate 1013, disposed inside the midframe structure, may include a third portion 10131, a bent portion 10133, and a fourth portion 10132. The bent portion 10133 connects the third portion 10131 and the fourth portion 10132. The fourth portion 10132 is further away from the light diffusion structure than the third portion 10131. Specifically, the bent portion 10133 bends away from the light diffusion structure 106.

[0147] The positional relationship between the back plate and the second support plate can be: Figure 16 The first section 1041 can be arranged opposite to the third part 10131, the bending section 1043 can be arranged opposite to the bending part 10133, and the second section 1042 can be arranged opposite to the fourth part 10132.

[0148] In some configurations, the fourth portion 10132 and the second section 1042 may be fixedly connected by a connecting structure, such that the back plate and the second support plate are fixedly connected. For example, the fourth portion 10132 and the second section 1042 may be connected by a threaded connector.

[0149] In order to improve the connection strength between the back plate and the second support plate, such as Figure 16 The threaded connector 108 can pass through the fourth portion 10132, the reinforcement rib 1044 and the second section 1042. Since the back plate is thicker at the location with the reinforcement rib, the connection strength between the back plate and the second support plate can be improved.

[0150] like Figure 16 In the example where the second support plate 1013 includes a third portion 10131 , a bent portion 10133 , and a fourth portion 10132 , the first section 1041 of the back plate may be located between the third portion 10131 and the third support plate 1014 .

[0151] In the structure that the second support plate 1013 can implement, the fourth portion 10132 can include multiple, such as Figure 17 and Figure 18 As shown, Figure 18 yes Figure 17 In this example, multiple fourth parts 10132 are included, and the multiple fourth parts 10132 can be arranged at intervals along the extension direction of the outer edge of the middle frame structure. Figure 18 In the figure, multiple fourth parts 10132 are arranged at intervals along the Y direction.

[0152] In order to improve the assembly efficiency of the back plate and the middle frame structure, or to improve the connection strength of the back plate and the middle frame structure, the embodiments of the present application also provide some structures.

[0153] For example, a snap-fit ​​structure can be provided at the matching position of the back plate and the middle frame structure. When assembling the back plate and the middle frame structure, the snap-fit ​​structure can be used for pre-assembly first, and then the above-mentioned Figure 16 The exemplary threaded connector 108 securely connects the back plate and the midframe structure.

[0154] like Figure 19 and Figure 20 , Figure 20 yes Figure 19 The clamping structure 110 in this example may include: a clamping slot 1101 and a clamping buckle 1102, one of which is provided on the back plate and the other is provided on the middle frame structure. Figure 20 In the embodiment, the card slot 1101 can be opened on the second support plate of the middle frame structure, such as being set on the fourth part 10132 of the second support plate, and the buckle 1102 is set on the second section 1042 of the back plate.

[0155] In some assembly processes, it is possible to Figure 20 The middle frame structure 101 is pushed in the P direction shown. During the pushing process, the buckle 1102 is elastically deformed so that the buckle 1102 is stuck in the slot 1101, thereby achieving pre-assembly of the back plate and the middle frame structure.

[0156] In some display devices, Figure 20 The clamping structure 110 may include multiple groups, and the multiple groups of clamping structures 110 may be arranged at intervals along the extension direction of the back plate edge, such as along Figure 19 The X and Y directions are shown as alternately arranged.

[0157] In some implementations, the slot 1101 may be disposed on the second section 1042 of the back plate, and the buckle 1102 may be disposed on the fourth portion 10132 of the second support plate of the middle frame structure.

[0158] In the example of this application, a limiting structure can be set at the matching position of the back plate and the middle frame structure. The limiting structure can prevent the back plate from moving in some directions relative to the middle frame structure, thereby improving the connection reliability of the back plate and the middle frame structure.

[0159] like Figure 20 The limiting structure 109 in this example is used to prevent the back plate from moving relative to the middle frame structure along a second direction, where the second direction is parallel to the extension direction of the back plate edge. For example, the limiting structure 109 is used to prevent the back plate from moving relative to the middle frame structure along the Y direction, or to prevent the back plate from moving relative to the middle frame structure along the X direction.

[0160] like Figure 20 The limiting structure 109 may include: a limiting column 1091 and a limiting groove 1092. The limiting groove 1092 may be arranged on the middle frame structure, for example, on the fourth part 10132 of the second support plate, and the opening of the limiting groove 1092 passes through the edge of the fourth part 10132. The limiting column 1091 is arranged on the second section 1042 of the back plate.

[0161] Since the opening of the limiting groove 1092 passes through the edge of the fourth portion 10132, when assembling the back plate and the middle frame structure, the limiting groove 1092 can be moved along the edge of the fourth portion 10132. Figure 20 The middle frame structure 101 is pushed in the P direction shown, and the limiting pillars 1091 can be inserted into the limiting grooves 1092 to prevent the back plate from moving relative to the middle frame structure in the X direction or the Y direction.

[0162] like Figure 20 The limiting structure 109 and the clamping structure 110 of the example of the present application can be arranged at intervals along the extension direction of the edge of the back panel.

[0163] The display device provided in this application has a plurality of achievable structures in the middle frame structure 101, such as Figure 21 , Figure 21 A schematic diagram of the structure of a middle frame structure 101 is shown. In this example, the middle frame structure 101 includes a frame 101B, which can be a strip-shaped plate structure. The frame 101B has opposing outer and inner walls, and the inner wall can enclose a space for accommodating the back panel 104. One end of a first support plate 1012 is connected to the inner wall of the frame 101B, and one end of a second support plate 1013 is connected to the inner wall of the frame 101B.

[0164] It can be understood that one end of the first support plate 1012 is directly connected to the inner wall of the frame 101B, and one end of the second support plate 1013 is directly connected to the inner wall of the frame 101B. In this way, the frame size of the display device can be reduced and the appearance of the display device can be optimized.

[0165] See Figure 21 The first support plate 1012, the second support plate 1013 and the frame 101B can be an integrally formed structural component, for example, they can be integrally formed by an injection molding process.

[0166] Figure 22 This is a partial structural diagram of another display device provided by an embodiment of the present application. In this implementation structure, a first support plate 1012 is provided inside the middle frame structure 101. The light source 105 is provided on the back plate 104, and the light diffusion structure 106 is provided on the first support plate 1012.

[0167] For example, the first support plate 1012 includes a first portion 1012A and a second portion 1012B. The light diffusion structure 106 may be connected to the first portion 1012A, and the second portion 1012B may fix the reflector 107 .

[0168] In this example, the first part 1012A of the first support plate 1012 is used to support the light diffusion structure 106, and the second part 1012B is tilted to support the reflector 107; and the first support plate 1012 is not connected to the back plate 104 and is decoupled. In this way, the back plate 104 can be decoupled from the position and volume of the first support plate 1012, making the design of the first support plate 1012 more free. For example, the volume will not be larger due to the constraints of the mixing distance.

[0169] See you next time Figure 22 A second support plate 1013 is further provided on the inner side of the middle frame structure 101, and the back plate 104 can be fixedly connected to the second support plate 1013. In addition, the end of the second portion 1012B of the first support plate 1012, which is away from the first portion 1012A, is not connected to the second support plate 1013 and is suspended in the air.

[0170] In some configurations, the second support plate 1013 may be fixedly connected to the back plate 104 via a threaded connection.

[0171] exist Figure 22 In this example, the middle frame structure 101 includes a frame 101B and an inner rib 101C. The frame 101B and the inner rib 101C are arranged opposite each other, and the inner wall of the inner rib 101C facing away from the frame 101B forms a space for accommodating the back panel 104. One end of the first support plate 1012 is connected to the inner wall of the inner rib 101C, and one end of the second support plate 1013 is connected to the inner wall of the inner rib 101C.

[0172] There is a gap between the frame 101B and the inner rib 101C, into which the edge of the back plate 104 can extend. For example, the edge of the back plate 104 can be bent at 90 degrees, and the bent portion can be inserted into the gap.

[0173] See Figure 22 The first support plate 1012, the second support plate 1013, the frame 101B, and the inner rib 101C can be an integrally formed structural component, for example, they can be integrally formed by an injection molding process.

[0174] In the different display devices in the above examples, the setting position of the light source and the setting position of the light diffusion structure are decoupled. The light source is set on the back panel, and the light diffusion structure is set on the middle frame structure. In this way, the back panel can be compatible with devices with different light mixing distances, thereby reducing the manufacturing cost of the device.

[0175] The structure of the first support plate for fixing the light diffusion structure is relatively simple, because when the light mixing distance changes the size of the middle frame structure, the size of the middle frame structure will basically not become larger. The size of the first support plate becomes larger, and occupies more space inside the display device.

[0176] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0177] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
