Technical Field

[0002] The present application relates to the field of display technology, and in particular to a display device and a frame assembly that can be used in the display device. Background Art

[0003] Display electronic devices, such as televisions and computers, have become widely popular. With the continuous development of science and technology and the continuous improvement of people's living standards, in order to meet people's demand for larger display screens and the pursuit of aesthetics of electronic devices, narrow bezels and higher screen-to-body ratios of such electronic devices have gradually become a development trend.

[0004] As shown in Figure 1, which exemplarily shows a partial structural diagram of a display device in the prior art, the display device may include a frame and a cover plate for protecting the display screen, wherein the cover plate is bonded to the frame by an adhesive layer made by a dispensing process.

[0005] To connect the cover plate to the frame, as shown in Figure 1, the frame has a boss, and the cover plate is supported on the boss. Furthermore, the display is connected to a circuit board, which needs to be bent, as shown in Figure 1. This requires a safety gap when the circuit board is bent. However, in Figure 1, the boss of the frame encroaches on the safety gap space of the circuit board. To ensure that the circuit board meets the design requirements for the safety gap, the display device would be larger in the P direction shown in Figure 1, making it difficult to achieve a narrow frame and a high screen-to-body ratio for the display device.

[0006] Summary of the Invention

[0007] The present application provides a display device that can be used as a frame assembly in the display device. The purpose is to reduce the frame size of the display device to achieve a narrow frame and a high screen-to-body ratio.

[0008] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0009] On the one hand, the present application provides a display device, for example, the display device can be a television, a tablet computer, a laptop computer, a desktop computer, etc., and the display device can be a device with a screen size greater than or equal to 14 inches.

[0010] The display device includes: a display structure, a frame and a cover plate; the frame is arranged on the periphery of the display structure; the cover plate includes a first part and a second part, the first part is located on the display surface side of the display structure, and the second part is arranged opposite to the frame

[0011] In addition, the second part of the cover includes a first section and a second section; a space for avoiding structural parts is formed between the first section and the reference surface, and between the second section and the reference surface; the distance between the first section and the reference surface is greater than the distance between the second section and the reference surface; the surface perpendicular to the display surface of the display structure is the reference surface.

[0012] The display device provided by the present application includes a cover plate that includes not only a first portion disposed on one side of the display surface of the display structure, but also a second portion disposed opposite the frame. For example, the first portion can serve as a protective structure to protect the display structure, and the second portion can be connected to the frame. In addition, in the display device provided by the present application, a space for evading structural components is formed between the first section of the cover plate and the reference surface, and between the second section of the cover plate and the reference surface. For example, a space for evading structural components can be provided. In addition, the spacing between the first section of the cover plate and the reference surface is greater than the spacing between the second section of the cover plate and the reference surface. In this way, the space for accommodating the bent portion of the circuit board is larger than the space for accommodating the extended portion of the circuit board. This can provide the circuit board with sufficient bending space, and the large bending space ensures a safe gap for the circuit board. Therefore, the solution provided by the present application can decouple the safe gap of the structural component (such as the circuit board) from the connection structure between the cover plate and the frame, so that the space occupied by the connection structure and the safe gap do not increase or decrease at the same time. In this way, on the basis of ensuring the safe gap of the circuit board, the frame size can be compressed to achieve a narrow frame and a high screen-to-body ratio.

[0013] In one achievable manner, the first section and the second section are continuous sections of the second portion, the first section is closer to the first portion than the second section, and an angle formed by the first portion and the second portion is less than 90°.

[0014] The first portion and the second portion of the cover plate form an angle less than 90°, that is, the second portion is tilted, so that the distance between the first portion and the reference surface is greater than the distance between the second portion and the reference surface.

[0015] In the example of the display device of the present application, the second part of the cover plate arranged opposite to the frame is arranged at an angle, or it can be understood that: from the back of the display structure to the display surface, the closer to the display structure, the greater the distance between the side of the display structure and the second part of the cover plate. In this way, more bending space can be reserved for the circuit board, and a safe gap of the circuit board can be guaranteed.

[0016] In one possible implementation, the frame includes a first side surface and a second side surface relative to each other, the first side surface being closer to the second portion than the second side surface; and from the back surface of the display structure toward the display surface, the distance between the first side surface and the second side surface decreases, so that the first side surface is an inclined surface, and the second portion is inclined on the inclined surface so that the distance between the first segment and the reference surface is greater than the distance between the second segment and the reference surface.

[0017] In this embodiment, the distance between the first side surface and the second side surface relative to the frame gradually decreases along the direction from the back of the display structure to the display surface, that is, the frame has a wedge-shaped structure. In this way, the accommodation space of the bent part of the circuit board can be larger than the accommodation space of the extended part.

[0018] In addition, the exposed, user-visible portion of the frame is narrower, allowing the structure including the frame and the cover to achieve a double-narrow effect.

[0019] In one possible implementation, the second portion of the cover plate includes a third side surface and a fourth side surface that are opposite to each other, the third side surface and the fourth side surface are parallel to each other, and the third side surface is arranged opposite to the first side surface.

[0020] In one possible implementation, the second part includes a third side and a fourth side facing each other, and the fourth side is closer to the frame than the third side; from the back of the display structure to the display surface, the distance between the third side and the fourth side decreases, so that the third side is an inclined surface, so that the distance between the first segment and the reference surface is greater than the distance between the second segment and the reference surface.

[0021] In this example, the second portion of the cover plate is a wedge-shaped structure.

[0022] In one possible implementation, the second portion of the cover plate is in a wedge-shaped structure, and the frame includes a first side surface and a second side surface that are opposite to each other, and the first side surface and the second side surface are parallel.

[0023] In one possible implementation, the second part of the cover includes a first end connected to the first part, and a second end opposite to the first end; the first section and the second section are both located between the first end and the second end; the first end is in contact with the frame on the side facing the frame.

[0024] It can be understood that: from the appearance of the display device, the cover plate and the frame are seamlessly connected, which can improve the appearance of the display device.

[0025] In one possible implementation, the second part of the cover includes a first end connected to the first part, and a second end opposite to the first end; the first end is in contact with the side of the frame toward the frame, pointing from the back of the display structure toward the display surface, and the surface of the frame in contact with the first end is inclined in a direction away from the side of the display structure.

[0026] The surface of the frame that fits with the cover is designed to be an inclined surface. In this way, during assembly, even if there is an assembly tolerance, the inclined surface can weaken the visual effect of the tolerance gap compared to the vertical surface, thereby improving the appearance.

[0027] In one possible implementation, the display device further includes an adhesive layer, which connects the frame and the second part, and the adhesive layer is arranged on a side away from the frame and in contact with the cover plate.

[0028] For example, an adhesive layer may be disposed between the first end and the second end of the second portion.

[0029] In this example, the cover plate and the frame are seamlessly connected from the outside of the display device, and the adhesive layer is hidden inside the display device. On the basis of ensuring the strength of the connection between the frame and the cover plate, the appearance of the display device can be further optimized.

[0030] In one possible implementation, the side of the second end facing the frame is in contact with the frame.

[0031] In one possible implementation, the frame has a groove at a position opposite to the second portion, and the adhesive layer is located in the groove.

[0032] By providing a groove and placing the adhesive layer in the groove, the frame size can be further compressed.

[0033] In one possible implementation, a glue overflow groove is provided on the bottom surface of the groove opposite to the second portion.

[0034] For example, when the adhesive layer is produced by a dispensing process, the overflow groove can be used to accommodate the flowing glue, thereby reducing the risk of the glue flowing to other locations.

[0035] In one possible implementation, a boss is formed on the side of the frame facing the circuit board. The boss is set at a position away from the position where the frame and the cover are in contact. The boss is used to limit the installation position of the second part, and the second end of the second part is located above the boss.

[0036] The provision of the boss not only limits the installation position of the cover plate, but also allows, in some scenarios, the gap between the first portion of the cover plate and the display structure to be adjusted according to different design requirements. For example, if the gap between the first portion of the cover plate and the display structure is large, the cover plate can be moved upward to increase the gap. Alternatively, if the gap between the first portion of the cover plate and the display structure is small, the cover plate can be moved downward to decrease the gap. In this way, the fit between the frame assembly (including the frame and the cover plate) and the display structure can be improved.

[0037] In one possible implementation, the frame includes a mating portion opposite to the second portion, and an elongated portion connected to the mating portion, wherein the side of the elongated portion facing the structural member protrudes more than the side of the second portion facing the structural member.

[0038] When installing the cover, the cover may be adjusted up and down along the frame, with the side of the cover facing the circuit board not exceeding the side of the frame. This can protect the circuit board when adjusting the cover and reduce the risk of the moving cover scratching the circuit board.

[0039] In one achievable manner, a protective layer is provided on the side of the second portion facing the structural member and / or the side of the elongated portion facing the structural member.

[0040] The protective layer can be used to protect the circuit board. For example, the protective layer can be made of Mylar material.

[0041] In one feasible manner, the first section and the second section are discontinuous sections of the second part, the first section and the second section are connected by a connecting section, and the first section is closer to the first part than the second section; the cover plate forms a first concave cavity at the position of the first section so that the distance between the first section and the reference surface is greater than the distance between the second section and the reference surface.

[0042] For example, the first cavity is arranged opposite to the bent portion of the circuit board. The first cavity can accommodate the bent portion, provide a larger space for the bent portion, and ensure a safe gap for the bent portion.

[0043] In one possible implementation, the frame has a second cavity at a position corresponding to the first section, and the first section is located in the second cavity.

[0044] Since a concave cavity is provided in the frame, the portion of the frame that is exposed and visible to the user is narrower, so that the structure including the frame and the cover plate achieves a double narrow effect.

[0045] In one possible implementation, the display device further includes an adhesive layer connecting the second segment and the frame.

[0046] In one possible implementation, the structural member includes a circuit board, which is located on the inner side of the cover plate and is connected to the display structure. The circuit board is bent and extended toward the back of the display structure, and the space between the first section and the reference surface and between the second section and the reference surface is used to avoid the circuit board.

[0047] In other examples, the structural member may also be other structures.

[0048] In one possible implementation, the border is a bottom border.

[0049] In some structures, the display device further includes other frames, which are connected to the bottom frame to form a frame structure of the display device.

[0050] On the other hand, the present application provides a frame assembly, which can be used in a display module, for example, in devices such as televisions, tablet computers, laptop computers, and desktop computers.

[0051] The frame assembly includes: a frame and a cover plate; the frame is used to be arranged on the periphery of the display structure of the display device; the cover plate includes a first part and a second part that are connected, the first part is used to be arranged on one side of the display surface of the display structure, and the second part is arranged opposite to the frame; the angle formed by the first part and the second part is less than 90°, the second part includes a first section and a second section, the first section and the second section are continuous sections of the second part, and a space for avoiding structural components in the display device is formed between the first section and the reference surface, and between the second section and the reference surface; the spacing between the first section and the reference surface is greater than the spacing between the second section and the reference surface; the surface perpendicular to the display surface of the display structure is the reference surface.

[0052] The frame assembly is used in a display device, which may include a circuit board electrically connected to a display structure. The circuit board needs to be bent to the back side of the display structure. In the frame assembly, the second part of the cover plate arranged opposite to the frame is arranged at an angle, which can be understood as: from the back of the display structure to the display surface, the closer to the display structure, the greater the distance between the side of the display structure and the second part of the cover plate. In this way, more bending space can be reserved for the circuit board, and a safe gap of the circuit board can be guaranteed.

[0053] In one possible implementation, the frame includes a first side surface and a second side surface relative to each other, the first side surface being closer to the second portion than the second side surface; and from the back surface of the display structure toward the display surface, the distance between the first side surface and the second side surface decreases, so that the first side surface is an inclined surface, and the second portion is inclined on the inclined surface so that the distance between the first segment and the reference surface is greater than the distance between the second segment and the reference surface.

[0054] The frame provided in this example has a wedge-shaped structure, which can provide a larger accommodating space for the bent portion of the circuit board and ensure a safe gap for the bent portion.

[0055] In one possible implementation, the second part includes a first end connected to the first part, and a second end opposite to the first end, and the first section and the second section are both located between the first end and the second end; the first end is in contact with the frame on the side facing the frame.

[0056] In this way, when viewed from the outside of the display device, the cover plate and the frame are seamlessly connected, which can improve the appearance of the display device.

[0057] In one possible implementation, the frame assembly further includes an adhesive layer, which connects the frame and the second part, and the adhesive layer is arranged on a side away from the frame and in contact with the cover plate.

[0058] The adhesive layer is hidden inside, which can further optimize the appearance of the display device.

[0059] In one possible implementation, the frame has a groove at a position opposite to the second portion, and the adhesive layer is located in the groove.

[0060] By utilizing the groove and arranging the adhesive layer in the groove, the frame size can be further compressed.

[0061] In one possible implementation, a glue overflow groove is provided on the bottom surface of the groove opposite to the second portion.

[0062] For example, when the adhesive layer is produced by a dispensing process, the overflow groove can be used to accommodate the flowing glue, thereby reducing the risk of the glue flowing to other locations.

[0063] In one possible implementation, a boss is formed on the side of the frame facing the circuit board. The boss is set at a position away from the position where the frame and the cover are in contact. The boss is used to limit the installation position of the second part, and the second end of the second part is located above the boss.

[0064] The provision of the boss not only limits the installation position of the cover plate, but also allows, in some scenarios, the gap between the first portion of the cover plate and the display structure to be adjusted according to different design requirements. For example, if the gap between the first portion of the cover plate and the display structure is large, the cover plate can be moved upward to increase the gap. Alternatively, if the gap between the first portion of the cover plate and the display structure is small, the cover plate can be moved downward to decrease the gap. In this way, the fit between the frame assembly (including the frame and the cover plate) and the display structure can be improved.

[0065] In one possible implementation, the frame includes a mating portion opposite to the second portion, and also includes an elongated portion connected to the mating portion, wherein the elongated portion protrudes compared to the second portion.

[0066] When installing the cover, the cover may be adjusted up and down along the frame, with the side of the cover facing the circuit board not exceeding the side of the frame. This can protect the circuit board when adjusting the cover and reduce the risk of the moving cover scratching the circuit board.

[0067] In one achievable manner, a protective layer is provided on the side of the second portion facing the circuit board and / or the side of the elongated portion facing the circuit board.

[0068] The protective layer can protect the circuit board.

[0069] In one possible implementation, the frame is a bottom frame in the display device.

[0070] On the other hand, the present application provides a frame assembly, which can be used in a display module.

[0071] The frame assembly includes: a frame and a cover plate; the frame is used to be arranged on the periphery of the display structure of the display device; the cover plate includes a first part and a second part that are connected, the first part is used to be arranged on one side of the display surface of the display structure, and the second part is arranged opposite to the frame, the second part includes a first section and a second section, and a connecting section connecting the first section and the second section, and a space for avoiding structural components in the display device is formed between the first section and the reference surface and between the second section and the reference surface; the cover plate forms a first concave cavity at the position of the first section, so that the distance between the first section and the reference surface is greater than the distance between the second section and the reference surface; the surface perpendicular to the display surface of the display structure is the reference surface.

[0074] In one possible implementation, the frame assembly further includes an adhesive layer connecting the second segment and the frame.

[0075] In one practicable manner, a protective layer is provided on the side of the second section facing the circuit board.

[0105] 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 display device. The present invention does not impose any particular restrictions on the specific form of the display device.

[0106] In some examples, the screen size of the display device can be greater than or equal to 14 inches. For example, it can be a 50-inch TV or a larger TV or screen. The TV can be a smart large screen.

[0107] FIG2 exemplarily shows a structural diagram of a display device 100 that is a television. The display device 100 includes a display structure 101, and the display structure 101 may include a display screen. The display screen may be a liquid crystal display (LCD) panel or a self-luminous display screen. In the case where the display screen is a self-luminous display screen, the display screen may be, for example, an organic light-emitting diode (OLED) display screen or a quantum dot light emitting diode (QLED) display screen. In the case where the display screen is a liquid crystal display screen, the above-mentioned display device 100 may be referred to as a liquid crystal display device; in the case where the display screen is a self-luminous display screen, the above-mentioned display device 100 may be referred to as a self-luminous display device.

[0108] Figure 3 is an exploded schematic diagram of a display device 100 according to an embodiment of the present application. The display device 100 further includes a frame assembly 102, a back panel 104, and a rear cover 103. The display structure 101 and the rear cover 103 are disposed on opposite sides of the frame assembly 102. The back panel 104 serves as the framework and carrier of the entire display device, and can accommodate most of the display device's structural components and electronic components, such as a controller, processor, field output integrated circuit, switching power supply module, speaker, cathode ray tube, and other functional components.

[0109] To meet people's demand for larger display screens, achieve narrow borders, and a higher screen-to-body ratio, for example, the size d of the bottom border in the border assembly can be reduced as shown in FIG2 .

[0110] In order to reduce the size of the frame and increase the screen-to-body ratio, this application exemplifies some possible structures, as described below.

[0111] As shown in FIG4 , FIG4 is a cross-sectional view of a portion of the structure of the display device according to an example of the present application, for example, it may be a cross-sectional view along the line AA shown in FIG3 .

[0112] As shown in FIG4 , this example includes a display structure 101, a frame 105, and a cover plate 106. The frame 105 is disposed on the periphery of the display structure 101. The exemplary frame 105 may be the bottom frame shown in FIG2 and FIG3 . The bottom frame and the remaining frames in the frame assembly (such as the side frames and the top frame) surround the periphery of the display structure 101, providing an external frame for the display structure 101.

[0113] In some display devices, the material of the bottom frame can be different from the material of the remaining frames. For example, in some scenarios, because the bottom frame needs to be placed on a supporting surface, the mechanical strength of the bottom frame needs to be greater than the mechanical strength of the remaining frames. For example, the bottom frame can be made of aluminum alloy.

[0114] As shown in FIG4 , the cover plate 106 includes a first portion 1061 and a second portion 1062 connected to each other. The first portion 1061 is located on the display surface side of the display structure 101 , and the second portion 1062 is disposed opposite to the frame 105 .

[0115] The display structure 101 has a display surface and a back surface, and the display surface is the side where the user can see the image.

[0116] The first portion 1061 of the cover plate 106 is disposed on the display surface side. The cover plate located on the display surface side can protect the display structure. In addition, the first portion 1061 of the cover plate 106 can also serve as a decorative piece.

[0117] The second portion 1062 of the cover plate 106 is located inside the frame 105 and is disposed opposite to the frame 105 .

[0118] In some examples, first portion 1061 and second portion 1062 may be integrally formed structures.

[0119] Alternatively, in some other examples, the first portion 1061 and the second portion 1062 are two independent structural members. In some instances, the first portion 1061 and the second portion 1062 can be connected by a connecting structure, for example, by an adhesive layer or a threaded connection.

[0120] As shown in FIG4 , in this example, the frame 105 and the cover 106 are two independent structural members. In other examples, the frame 105 and the cover 106 may be an integrally formed member.

[0121] The frame 105 and the cover plate 106 may be made of the same or different materials. For example, the frame 105 may be made of aluminum alloy, and the cover plate 106 may be made of stainless steel.

[0122] In some display devices, as shown in FIG4 , a space 107 is formed inside the first portion 1061 and the second portion 1062 of the cover 106. The space 107 can accommodate some structural components of the display device, such as a circuit board 108 connected to the display structure 101.

[0123] The circuit board 108 electrically connected to the display structure 101 needs to transmit the electrical signal of the display structure 101 to the main board of the display device, so that the control device on the main board applies the control signal to the display device.

[0124] In some examples, the mainboard of the display device can be set on the back panel, as shown in Figure 4, the circuit board 108 is bent in the space 107 and extends away from the back of the display structure 101, and is electrically connected to the mainboard to achieve signal communication between the display structure 101 and the mainboard.

[0125] It can also be understood that the space 107 can be used as an avoidance space for structural parts (such as circuit boards) in the display device. In some structures, such as when setting up a circuit board, there are design requirements for the space 107 used for avoidance. For example, as shown in Figure 4, the bent part of the circuit board 108 has a large enough space to ensure the bending radius and the safety gap, and cannot interfere with other structural parts and affect the performance of the circuit board.

[0126] In order to ensure that the avoidance space 107 meets the requirements, as shown in Figure 5, the second part 1062 of the cover plate 106 may include a first section 106A and a second section 106B, wherein a space for avoiding structural parts, such as the circuit board 108, is formed between the first section 106A and the reference surface L, and between the second section 106B and the reference surface L, and the reference surface L is perpendicular to the display surface of the display structure 101.

[0127] Furthermore, a distance S1 between the first segment 106A and the reference plane L is greater than a distance S2 between the second segment 106B and the reference plane L.

[0128] In the example of this application, the distance S1 between the first segment 106A and the reference surface L can be understood as the distance between the wall surface of the first segment 106A facing the inside of the display device and the reference surface L; the distance S2 between the second segment 106B and the reference surface L can be understood as the distance between the wall surface of the second segment 106B facing the inside of the display device and the reference surface L.

[0129] In some examples, as shown in FIG5 , the space between first segment 106A and reference plane L can accommodate bent portion 108A of circuit board 108, and the space between second segment 106B and reference plane L can accommodate extended portion 108B of circuit board 108. Bend portion 108A comprises an arc-shaped segment of the circuit board, and extended portion 108B comprises at least a portion extending away from the back surface of display structure 101.

[0130] FIG. 5 schematically illustrates the bent portion 108A and the extended portion 108B of the circuit board 108 . The illustrated bent portion 108A and the extended portion 108B do not constitute an absolute limitation on the positions of the two portions.

[0131] In the example of the present application, since the bending portion 108A is arranged in a larger space between the first section 106A and the reference surface L, the bending portion 108A can be given a sufficiently large bending space. In the sufficiently large avoidance space, the bending portion 108A is ensured to have a larger bending radius and a larger safety gap, thereby avoiding interference between the circuit board and other structural parts when bending, or scratching between the bending portion 108A and other structural parts when the display device is in use.

[0132] In some structures, a side surface M of the display structure 101 may be used as a reference surface L, and the side surface M may be perpendicular to the display surface of the display structure 101 .

[0133] In some possible structures, the display structure 101 includes a light source, a lower polarizer 1011 , an upper polarizer 1014 , a substrate 1012 with a plurality of thin film transistors, and a color filter 1013 .

[0134] The light source projects light, which passes through the lower polarizer 1011 and then the thin film transistor. Next, the light must pass through the color filter 1013 and another upper polarizer 1014.

[0135] In some examples, as shown in FIG5 , the edge of the substrate 1012 having many thin film transistors is more protruding than other film layer structures because the circuit board 108 needs to be bound (also called connected). A bonding area is provided at the edge of the substrate 1012 having many thin film transistors, and the circuit board 108 is connected to the bonding area.

[0136] The side surface of the substrate 1012 on which many thin film transistors are formed can be shown as a reference surface L surface.

[0137] As shown in FIG5 , the second portion 1062 of the cover plate 106 includes a first segment 106A and a second segment 106B, which can be arranged along the direction from the display surface to the back surface, that is, the first segment 106A and the second segment 106B are arranged in sequence along the direction from the display surface to the back surface.

[0138] In some examples, as shown in FIG6 , the second portion 1062 may further include a third segment ( 106C). The first segment 106A, the second segment 106B, and the third segment ( 106C) may be arranged sequentially from the display surface to the back surface. Alternatively, the first segment 106A, the third segment ( 106C), and the second segment 106B may be arranged sequentially from the display surface to the back surface; or, as shown in FIG6 , the third segment 106C, the first segment 106A, and the second segment 106B may be arranged sequentially from the display surface to the back surface.

[0139] When the second portion further includes a third segment 106C, as shown in FIG6 , the third segment 106C, the first segment 106A, and the second segment 106B can be sequentially arranged along the direction from the display surface to the back surface, and the spacing S3 between the third segment 106C and the reference surface L can be greater than the spacing S1 between the first segment 106A and the reference surface L. Alternatively, the first segment 106A, the second segment 106B, and the third segment (106C) can be sequentially arranged along the direction from the display surface to the back surface, and the spacing (S3) between the third segment 106C and the reference surface L can be smaller than the spacing S2 between the second segment 106B and the reference surface L. For example, the extended portion 108B of the circuit board 108 can continue to extend into the space between the third segment (106C) and the reference surface L.

[0140] As shown in FIG6 , when assembling the display device, the installation position of the cover plate 106 can be adjusted up and down (e.g., along the Z direction in FIG6 ). In some structures, the designed gap X between the display surface of the display structure 101 and the first portion 1061 of the cover plate 106 varies. For example, the designed gap X between the display surface of some display structures 101 and the first portion 1061 is larger, while the designed gap X between the display surface of other display structures 101 and the first portion 1061 is smaller.

[0141] The present application can meet the gap X requirements of different screens and match different display screens by adjusting the position of the cover plate 106 up and down.

[0142] In order to achieve that the distance S1 between the first segment 106A and the reference surface L is greater than the distance S2 between the second segment 106B and the reference surface L, the present application provides a variety of structures that can be implemented.

[0143] As shown in FIG7 and FIG8 , FIG7 and FIG8 show two different structures of the frame 105 and the cover plate 106 .

[0144] In the two different examples of Figures 7 and 8, the angle α formed by the first part 1061 and the second part 1062 is less than 90°, the first segment 106A and the second segment 106B are continuous segments of the second part 1062, and the first segment 106A is closer to the first part 1061 than the second segment 106B.

[0145] It can be understood that: in Figures 7 and 8, along the direction pointing to the back of the display surface, the second part 1062 gradually tilts toward the inside of the display device, so that the distance S2 between the second segment 106B and the reference surface L is smaller than the distance S1 between the first segment 106A and the reference surface L.

[0146] 9 shows an exploded view of the frame 105 and the cover 106 in the example of FIG7. The frame 105 has a first side and a second side opposite to each other. In conjunction with FIG9 and FIG7, the first side is closer to the second portion 1062 of the cover 106 than the second side.

[0147] As shown in Figure 9, from the back of the display structure to the display surface, the distance between the first side surface and the second side surface decreases, so that the first side surface is an inclined surface, and the second part 1062 of the cover plate 106 is tilted on the first side surface so that the distance S1 between the first section 106A and the reference surface L is greater than the distance S2 between the second section 106B and the reference surface L.

[0148] In this example, the frame 105 is a wedge-shaped structure, and the width of the user-visible portion is relatively small. To match the wedge-shaped frame 105, as shown in FIG9 , the angle α between the first portion 1061 and the second portion 1062 of the cover 106 is less than 90°.

[0149] 9 , the second portion 1062 of the cover plate 106 includes a third side surface and a fourth side surface. The third side surface and the fourth side surface are parallel to each other, or approximately parallel to each other due to factors such as manufacturing process. The fourth side surface is closer to the frame 105 than the third side surface. That is, the fourth side surface of the cover plate 106 and the first side surface of the frame 105 are disposed opposite each other.

[0150] In the display device, as shown in Figure 7, the closer the frame 105 is to the top visible to the user, the smaller the force on the frame. The frame 105 of the present application adopts a wedge-shaped structure, and the wider lower part can support the force of the frame. In addition, the top of the frame is narrower, which can achieve the effect of the frame itself having a narrow frame. Therefore, as shown in Figure 7, the present application can not only achieve a narrow frame and a large screen-to-body ratio for the entire display device, but also make the frame itself have a narrow frame effect, realizing a double narrow frame of the display device, and further optimizing the appearance.

[0151] Referring to Figure 10 , it shows an exploded view of the frame 105 and cover plate 106 in the example of Figure 8 . In this implementation, the distance between the third and fourth sides of the second portion 1062 of the cover plate 106 decreases from the back of the display structure toward the display surface, making the third side an inclined surface. This allows the distance between the first section and the reference surface to be greater than the distance between the second section and the reference surface. In other words, in this example, the second portion 1062 of the cover plate 106 has a wedge-shaped structure.

[0152] Continuing to refer to FIG10 , the first side surface and the second side surface of the frame 105 are parallel.

[0153] In the different examples shown in Figures 9 and 10, whether the frame 105 is designed as a wedge-shaped structure or the second part 1062 of the cover 106 is designed as a wedge-shaped structure, avoidance spaces with different spacings can be formed between different sections of the second part 1062 and the reference surface to ensure that the circuit board 108 meets the assembly process requirements.

[0154] To enhance the aesthetics of the display device, the frame size is compressed, as shown in Figures 7 and 8. The user-visible cover portion is aligned with the frame portion. In some assembly structures, a smaller assembly tolerance is provided between the user-visible cover portion and the frame portion, resulting in a smaller gap, for example, less than or equal to 0.125 mm.

[0155] 7 , the second portion 1062 of the cover 106 includes a first end 1062A connected to the first portion 1061 and a second end 1062B opposite the first end 1062A. The first end 1062A faces the side of the frame 105 and is in contact with the frame 105.

[0156] In some examples, the first segment 106A and the second segment 106B are both located between the first end 1062A and the second end 1062B, with the first segment 106A being closer to the first end 1062A than the second segment 106B.

[0157] In order to further enhance the appearance of the display device, as shown in FIG11 , FIG11 shows a decomposition diagram of the frame 105 and the cover plate 106. The surface of the frame 105 that is in contact with the first end of the cover plate 106 is an inclined surface 105A, which points from the back of the display structure to the display surface. The inclined surface 105A of the frame that is in contact with the first end is inclined in a direction away from the side of the display structure, or it can be understood as: from the display surface of the display structure to the back direction, the inclined surface 105A is inclined toward the inside of the display device.

[0158] The surface of the frame 105 that fits with the first end of the cover 106 is designed to be an inclined surface. In this way, even if there are design tolerances or assembly tolerances, from the appearance of the display device, the frame 105 and the cover 106 are basically in contact, which can weaken the visual effect of the gap and improve the appearance.

[0159] In some examples, when the frame 105 and the cover plate 106 are two independent structural members, a connecting structure can be used to connect the frame 105 and the cover plate 106 .

[0160] As shown in Figure 12, Figure 12 exemplarily shows a schematic diagram of the connection relationship between the frame 105 and the cover plate 106. The second portion 1062 of the cover plate 106 can be connected to the frame 105, for example, the frame 105 and the second portion 1062 of the cover plate 106 can be bonded together using an adhesive layer 109.

[0161] In this example, the adhesive layer 109 is hidden, as shown in FIG12 , and is disposed on the side away from the frame 105 and the cover plate 106. In this way, the adhesive layer 109 is not visible from the outside of the display device, which can further improve the appearance of the display device.

[0162] As shown in FIG13 , in order to reduce the bezel size of the display device and increase the screen-to-body ratio, in some structures, a groove 105B can be provided in the bezel 105 at a position opposite the second portion 1062 of the cover plate 106, and the adhesive layer 109 can be disposed in the groove 105B. Alternatively, a groove can be provided in the second portion 1062 of the cover plate 106, and the adhesive layer 109 can be disposed in the groove of the cover plate.

[0163] In some examples, the adhesive layer 109 can be made by a pasting process, for example, double-sided tape can be used to adhere the cover plate 106 and the frame 105, which can also reduce manufacturing costs. Alternatively, in other examples, the adhesive layer 109 can be made by a coating process.

[0164] In a feasible process, in order to prevent the liquid colloid from overflowing from the groove 105B, as shown in FIG13 , a glue overflow groove 110 is formed on the bottom surface of the groove 105B opposite to the second portion 1062 .

[0165] A plurality of glue overflow grooves 110 may be provided, and the plurality of glue overflow grooves 110 may be arranged at intervals along the extending direction of the groove 105B. For example, in FIG. 13 , two glue overflow grooves 110 are provided.

[0166] The present application does not impose any particular limitation on the shape and size of the overflow groove 110. For example, an arc-shaped groove, a rectangular groove, etc. may be used.

[0167] In some processes, for example, when using double-sided tape to bond the cover plate 106 and the frame 105, the thickness of the double-sided tape is greater than the depth of the groove 105B. After applying pressure, ensure that the adhesive layer is compressed and the exposed part of the cover plate 106 and the frame 105 are tightly attached, thereby improving the appearance of the display device.

[0168] Continuing with FIG13 , the side of the frame 105 facing the interior of the display device has a boss 111. The second end of the second portion 1062 of the cover plate 106 is positioned above the boss 111. This boss 111 defines the lower limit of the cover plate 106 during installation. This prevents the cover plate 106 from being misaligned during installation and potentially damaging components within the display device, such as the circuit board.

[0169] In some examples, as shown in Figure 14, the frame 105 not only includes a mating portion 1051 opposite to the cover plate 106, but also includes an extension portion 1052 connected to the mating portion 1051. The extension portion 1052 can be connected to other structural members, for example, it can be connected to the back cover of the display device. The side P surface of the extension portion 1052 facing the interior of the display device is more protruding than the third side surface of the second portion 1062 of the cover plate 106 facing the interior of the display device.

[0170] For example, the avoidance space in the example of this application is to make room for the circuit board 108 to be installed. The circuit board 108 is easily scratched by surrounding structural components. Therefore, in the example of Figure 14, it can be connected to the back cover of the display device, and the side of the extended portion 1052 facing the interior of the display device is more protruding than the side of the second portion 1062 of the cover plate 106 facing the interior of the display device. In this way, the circuit board 108 can be reduced from being scratched by the harder cover plate 106 or frame 105.

[0171] As shown in FIG14 , in this example, the side surface P of the extension portion 1052 is a vertical surface. In other examples, the side surface P of the extension portion 1052 may also be an inclined surface.

[0172] In order to further protect the circuit board 108, as shown in Figure 15, a protective layer 112 can be set on the side of the second part 1062 of the cover plate 106 facing the interior of the display device, or a protective layer 112 can be set on the side of the extended part 1052 of the frame 105 facing the interior of the display device, or a protective layer 112 can be set on the side of the second part 1062 of the cover plate 106 facing the interior of the display device, and a protective layer 112 can be set on the side of the extended part 1052 of the frame 105 facing the interior of the display device.

[0173] The protective layer 112 can reduce the risk of the circuit board 108 being scratched by the cover plate or the frame, thereby improving the yield of the display device.

[0174] There are many materials that can be selected for the protective layer 112, for example, at least one of Mylar, foam, and rubber strips can be selected.

[0175] Figures 16 and 17 illustrate another embodiment of the present invention, illustrating a structure that allows for space to be created for components within a display device (e.g., circuit board 108). In this example, a frame 105 and a cover 106 are provided. Cover 106 includes a first portion 1061 and a second portion 1062 that are connected. First portion 1061 is located on the display surface side of display structure 101, while second portion 1062 is positioned opposite frame 105.

[0176] The first portion 1061 and the second portion 1062 of the cover plate 106 define a space 107 therein. The space 107 can accommodate a structural component such as a circuit board 108 .

[0177] As shown in FIG17 , the second portion 1062 of the cover plate 106 includes a first segment 106A and a second segment 106B. The first segment 106A and the second segment 106B are discontinuous. Furthermore, the second portion 1062 further includes a connecting segment 106D connecting the first segment 106A and the second segment 106B.

[0178] In the example of FIG17 , first segment 106A is closer to first portion 1061 of the cover plate than second segment 106B. Cover plate 106 forms a first cavity 113 at the location of first segment 106A. This cavity widens space 107, making the distance S1 between first segment 106A and reference plane L greater than the distance S2 between second segment 106B and reference plane L. Reference plane L in this example is perpendicular to the display surface of display structure 101.

[0179] The explanation of the reference surface L-plane in this example can refer to the reference surface L-plane in the above example.

[0180] In this embodiment, the distance S1 between the first segment 106A and the reference surface L can be understood as the distance between the surface of the first cavity 113 facing the interior of the display device and the reference surface L; the distance S2 between the second segment 106B and the reference surface L can be understood as the distance between the surface of the second segment 106B facing the interior of the display device and the reference surface L.

[0181] 17 , the space between the first section 106A and the reference surface L can provide space for the bent portion 108A of the circuit board 108 , and the space between the second section 106B and the reference surface L can provide space for the extended portion 108B of the circuit board 108 .

[0182] By providing a concave cavity at the position of the first section 106A, a larger space is created between the first section 106A and the reference surface L, thereby providing the circuit board 108 with a sufficiently large bending space to ensure that the bending space meets the safety clearance requirement.

[0183] In some examples, the space between the second segment 106B and the reference plane L may avoid at least a portion of the extended portion 108B of the circuit board 108 .

[0184] 17 , the frame 105 has a second cavity 114 at a position corresponding to the first segment 106A, and the first segment 106A is located within the second cavity 114 .

[0185] As shown in Figure 17, due to the opening of the second cavity 114 on the frame 105, the width of the portion of the frame 105 visible to the user is narrower, which can also achieve the effect of the frame itself having a narrow frame. Therefore, as shown in Figure 17, the present application can not only achieve a narrow frame and a large screen-to-body ratio for the entire display device, but also make the frame itself have a narrow frame effect, thereby realizing a double narrow frame of the display device and further optimizing the appearance.

[0186] As shown in Figure 18 , the exploded view of the frame 105 and the cover 106 is shown. In this example, the height h1 of the second cavity 114 formed on the frame 105 is greater than the height h2 of the first section 106A of the cover 106 .

[0187] In this way, when installing the cover plate 106, the installation position of the cover plate 106 can be adjusted up and down to meet the gap X requirements of different screens and match different display screens.

[0188] The height dimension h1 of the second cavity 114 and the height dimension h2 of the first segment 106A can be understood as dimensions in a direction perpendicular to the display surface of the display structure, or dimensions in a direction parallel to the reference surface L.

[0189] In the examples of Figures 16 and 17, the second section 106B of the cover plate 106 can be connected to the frame 105 via an adhesive layer 109. In this way, this example adopts a hidden connection structure that is invisible to the user and can improve the appearance.

[0190] In some examples, a groove may be formed at a position of the frame 105 opposite to the second section 106B, and the adhesive layer 109 is disposed in the groove. Alternatively, a groove may be formed on the second section 106B of the cover plate 106, and the adhesive layer 109 is disposed in the groove.

[0191] In some other examples, the frame 105 and the cover 106 may also be an integral structure.

[0192] To protect the circuit board 108 , a protective layer may be provided on the side of the second section 106B of the cover plate 106 facing the circuit board 108 . A protective layer may also be provided on the side of the frame 105 facing the circuit board 108 .

[0193] There are many materials that can be selected for the protective layer, for example, at least one of Mylar, foam, adhesive strip, etc. When Mylar is selected to make the protective layer, the protective layer is thinner and does not occupy a large space.

[0194] As shown in FIG17 , the display device of the example of the present application may also include a light source and an optical structure for processing light from the light source. After the light emitted by the light source is processed by the optical structure, it may be projected to the user through the display structure 101 to display the image.

[0195] For example, the optical structure can be one or a combination of a reflective sheet 117, a diffuser 116, a brightness enhancement sheet 115, or a prism. The main function of the optical structure is to fully diffuse or aggregate the light passing through the optical structure, increase the light utilization rate, or transform a point light source into a surface light source, thereby improving the display effect.

[0196] The back plate 104 , which serves as a supporting frame for the entire display device, can be used to support the aforementioned optical structures.

[0197] The above application provides several possible design schemes in combination with the accompanying drawings. In some other possible examples covered by this application, the interior of the display screen may also include multiple structural parts that need to be avoided. In this case, you can refer to the similar scheme provided by this application and set avoidance space for each of the multiple structural parts through a multi-stage avoidance design, thereby providing a safe gap space for the multiple structural parts while achieving a narrow bezel design of the display device.

[0198] 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.

[0199] 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.
