Display equipment and frame assemblies

Abstract

A display device (100) and a frame assembly (102) are disclosed. The display device (100) includes a display structure (101), a frame (105), and a cover plate (106). The frame (105) is positioned around the display structure (101). The cover plate (106) includes a first portion (1061) and a second portion (1062) that are connected, the first portion (1061) being located on the display surface side of the display structure (101), and the second portion (1062) being located on the opposite side of the frame (105). Furthermore, the second portion (1062) of the cover plate (106) includes a first segment (106A) and a second segment (106B). Spaces (107) for avoiding mechanical parts are formed between the first segment (106A) and a reference surface (surface L), and between the second segment (106B) and the reference surface (surface L). The distance (S1) between the first segment (106A) and the reference surface (surface L) is greater than the distance (S2) between the second segment (106B) and the reference surface (surface L). The reference surface (surface L) is the surface perpendicular to the display surface of the display structure (101). For example, if the mechanical part is a circuit board (108), the large distance between the first segment (106A) and the reference surface (surface L) allows for a large bending avoidance space to be secured when bending the circuit board (108), thereby ensuring a safe clearance.

Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly, to display devices and frame assemblies that can be used in such display devices.

Background Art

[0002] Display electronic devices such as televisions and computers are widely used. With the continuous development of technology and the continuous improvement of people's living standards, the frame narrowing and high screen occupancy ratio (screen-to-body ratio) of such electronic devices have gradually become development trends in order to meet people's requirements for larger screens in displays and the pursuit of the aesthetics of electronic devices.

[0003] FIG. 1 is a diagram showing an example of a partial structure of a display device in the prior art. The display device may include a frame and a cover plate capable of protecting the display. The cover plate is joined to the frame via an adhesive layer manufactured using a gel dispensing process.

[0004] To connect the cover plate and the frame, as shown in FIG. 1, the frame has bosses and the cover plate is supported on the bosses. Also, a circuit board is connected to the display and the circuit board needs to be bent. As shown in FIG. 1, the circuit board needs to ensure a safety clearance when bent. However, in FIG. 1, the bosses of the frame occupy the safety clearance space of the circuit board. In order for the circuit board to meet the design requirements regarding the safety clearance, the display device has a large size in the P direction shown in FIG. 1. As a result, it is difficult to achieve frame narrowing and a high screen occupancy ratio of the display device.

Summary of the Invention

[0005] This invention provides a display device and a frame assembly that can be used with a display device, which reduce the frame size of the display device and achieve a narrower frame and a higher screen-to-body ratio.

[0006] To achieve the above objective, the embodiments of this application employ the following technical solutions.

[0007] In one embodiment, the present invention provides a display device. For example, the display device may be a device such as a television, tablet computer, laptop computer, or desktop computer, and the display device may be a device with a screen size of 14 inches or larger.

[0008] The display device includes a display structure, a frame, and a cover plate. The frame is positioned around the display structure. The cover plate includes a first part and a second part, the first part positioned on the side of the display surface of the display structure, and the second part positioned on the opposite side of the frame.

[0009] Furthermore, the second portion of the cover plate includes the first segment and the second segment. Spaces for avoiding mechanical parts are formed between the first segment and the reference plane, and between the second segment and the reference plane. The distance between the first segment and the reference plane is greater than the distance between the second segment and the reference plane. The reference plane is the plane perpendicular to the display surface of the display structure.

[0010] In the display device provided in this application, the cover plate includes not only a first portion positioned on the display surface side of the display structure, but also a second portion positioned opposite the frame. For example, the first portion may be used as a protective structure to protect the display structure, and the second portion may be connected to the frame. Furthermore, in the display device provided in this application, space for avoiding mechanical parts is formed between the first segment of the cover plate and the reference surface, and between the second segment and the reference surface. For example, space for avoiding a circuit board may be provided. Moreover, the distance between the first segment of the cover plate and the reference surface is greater than the distance between the second segment and the reference surface. This allows the space for accommodating the bent portion of the circuit board to be greater than the space for accommodating the extended portion of the circuit board. In this way, sufficient bending space can be provided for the circuit board, and this wide bending space ensures a safe clearance for the circuit board. Therefore, in the solution provided in this application, the safe clearance for mechanical parts (e.g., circuit boards) can be separated from the connection structure between the cover plate and the frame, and the space occupied by the connection structure and the safe clearance do not change in inverse proportion. In this way, the frame size can be reduced while ensuring safe clearance for the circuit board, achieving both a narrower frame and a high screen-to-body ratio.

[0011] In possible embodiments, the first and second segments are continuous segments of the second part, the first segment is closer to the first part than the second segment, and the angle between the first and second parts is less than 90°.

[0012] The first and second portions of the cover plate form a narrow angle of less than 90°. In other words, the second portion is positioned at an angle such that the distance between the first segment and the reference plane is greater than the distance between the second segment and the reference plane.

[0013] In an example of the display device of the present invention, the second portion of the cover plate, which is positioned opposite the frame, is positioned at an angle. Alternatively, in the direction from the back of the display structure toward the display surface, the distance between the side of the display structure and the second portion of the cover plate can be interpreted as being wider closer to the display structure. This allows for more bending space for the circuit board and ensures a safe clearance for the circuit board.

[0014] In possible embodiments, the frame has a first side and a second side facing each other, the first side being closer to the second portion than the second side. The distance between the first and second sides decreases in the direction from the back of the display structure toward the display surface, the first side becomes an inclined surface, the second portion is positioned at an angle to the inclined surface, and the distance between the first segment and the reference plane is greater than the distance between the second segment and the reference plane.

[0015] In this embodiment, the distance between the first and second opposing sides of the frame gradually decreases in the direction from the back of the display structure toward the display surface. In other words, the frame has a wedge-shaped structure. This allows the space for accommodating the bent portion of the circuit board to be larger than the space for accommodating the extended portion.

[0016] Furthermore, because the exposed portion of the frame that is visible to the user becomes smaller, a narrowing effect occurs in both the frame and the cover plate that make up the structure.

[0017] In possible embodiments, the second portion of the cover plate includes a third and a fourth side facing each other, the third side being parallel to the fourth side and the third side being positioned opposite to the first side.

[0018] In possible embodiments, the second portion includes a third and a fourth side facing each other, the fourth side being closer to the frame than the third side. The distance between the third and fourth sides decreases in the direction from the back of the display structure toward the display surface, the third side becomes an inclined surface, and the distance between the first segment and the reference plane is greater than the distance between the second segment and the reference plane.

[0019] In this example, the second portion of the cover plate has a wedge-shaped structure.

[0020] In possible embodiments, the second portion of the cover plate has a wedge-shaped structure, and the frame includes a first side and a second side that are opposite to each other, with the first side being parallel to the second side.

[0021] In possible embodiments, the second portion of the cover plate includes a first end connected to the first portion and a second end opposite to the first end, with both the first and second segments located between the first and second ends. The side of the first end facing the frame is attached to the frame.

[0022] From an external perspective, the cover plate can be interpreted as seamlessly connected to the frame of the display device. This improves the aesthetic appearance of the display device.

[0023] In possible embodiments, the second portion of the cover plate includes a first end connected to the first portion and a second end opposite to the first end. The side of the first end facing the frame is attached to the frame. In the direction from the back of the display structure toward the display surface, the frame surface attached to the first end is inclined away from the side of the display structure.

[0024] The surface of the frame that is attached to the first end is designed as an inclined surface. Thereby, during assembly, even if there are assembly tolerances, the inclined surface can reduce the visual impact caused by the tolerance gap compared to a vertical surface and improve the aesthetic appearance.

[0025] In a possible embodiment, the display device further includes an adhesive layer, the adhesive layer connects the frame to the second part, and the adhesive layer is disposed on the side away from the frame and on the side attached to the cover plate.

[0026] For example, the adhesive layer may be disposed between the first end and the second end of the second part.

[0027] In this example, when viewed from the appearance of the display device, the cover plate is seamlessly connected to the frame, and the adhesive layer is hidden inside the display device. By ensuring the connection strength between the frame and the cover plate, the aesthetic appearance of the display device can be further optimized.

[0028] In a possible embodiment, the side surface of the second end that faces the frame is attached to the frame.

[0029] In a possible embodiment, a groove is disposed at the position of the frame on the side opposite to the second part, and the adhesive layer is located within the groove.

[0030] By disposing the groove and locating the adhesive layer within the groove, the frame size can be further reduced.

[0031] In a possible embodiment, an adhesive overflow groove is disposed at the bottom surface of the groove on the side opposite to the second part.

[0032] For example, when manufacturing the adhesive layer using a gel dispensing process, the adhesive overflow groove is used to accommodate the flowing adhesive and can reduce the risk of the adhesive flowing out to other positions.

[0033] In possible embodiments, the boss is formed on the side of the frame that faces the circuit board. The boss is located away from the frame and in a position where it is attached to the cover plate. The boss is configured to restrict the mounting position of the second portion, with the second end of the second portion resting on the boss.

[0034] By positioning bosses, the mounting position of the cover plate can be restricted. Furthermore, in some cases, the gap between the first part of the cover plate and the display structure can be adjusted based on different design requirements. For example, if the design gap between the first part of the cover plate and the display structure is large, the cover plate can be moved upward to widen the gap. Alternatively, if the design gap between the first part of the cover plate and the display structure is small, the cover plate can be moved downward to narrow the gap. In this way, the fit between the frame assembly (including the frame and cover plate) and the display structure can be improved.

[0035] In possible embodiments, the frame includes a mating portion opposite to the second portion, and further includes an elongated component connected to the mating portion, wherein the side of the elongated component facing the mechanical component protrudes from the side of the second portion facing the mechanical component.

[0036] Once the cover plate is installed, it can be adjusted up and down along the frame, and the side of the cover plate facing the circuit board does not extend beyond the side of the frame. In this way, the circuit board can be protected when adjusting the cover plate, and the possibility of the circuit board being damaged by the movable cover plate is reduced.

[0037] In possible embodiments, protective layers are provided on the sides of the second portion that face the mechanical component and / or on the sides of the elongated component that face the mechanical component.

[0038] A protective layer can be used to protect the circuit board. For example, the protective layer may be made of Mylar material.

[0039] In possible embodiments, the first and second segments are discontinuous segments of the second portion, connected by a connecting segment, with the first segment being closer to the first portion than the second segment. A first concave cavity is formed at the location of the first segment of the cover plate, and the distance between the first segment and the reference plane is greater than the distance between the second segment and the reference plane.

[0040] For example, the first recessed cavity may be positioned opposite the bent portion of the circuit board, and the first recessed cavity may house the bent portion, thereby providing a larger space for the bent portion and ensuring a safe clearance for the bent portion.

[0041] In possible embodiments, the second recessed cavity is formed at a position on the frame corresponding to the first segment, and the first segment is located within the second recessed cavity.

[0042] Because the concave cavity is positioned on the frame, the exposed portion of the frame that is visible to the user is reduced, resulting in a narrower overall structure for both the frame and the cover plate.

[0043] In possible embodiments, the display device further includes an adhesive layer which connects a second segment to a frame.

[0044] In possible embodiments, the mechanical components include a circuit board, which is located inside a cover plate, is connected to a display structure, and extends in a curve toward the back of the display structure, with spaces between the first segment and the reference plane, and between the second segment and the reference plane, to avoid the circuit board.

[0045] In other examples, the machine part could be of a different structure instead.

[0046] In possible embodiments, the frame is the lower frame.

[0047] In some structures, the display device further includes another frame, which is connected to the lower frame to form the frame structure of the display device.

[0048] In another embodiment, the present invention provides a frame assembly which can be used in a display module and can be used in devices such as a television, tablet computer, laptop computer, or desktop computer.

[0049] The frame assembly includes a frame and a cover plate. The frame is configured to be positioned around the display structure of the display device. The cover plate includes a first and second part to be connected, the first part being positioned on the side of the display surface of the display structure, and the second part being positioned on the opposite side of the frame, with an angle between the first and second parts being less than 90°, the second part including a first segment and a second segment, the first and second segments being continuous segments of the second part, and space for avoiding mechanical parts within the display device is formed between the first segment and the reference plane, and between the second segment and the reference plane. The distance between the first segment and the reference plane is greater than the distance between the second segment and the reference plane. The reference plane is the plane perpendicular to the display surface of the display structure.

[0050] Frame assemblies are used in display devices. Display devices may include circuit boards electrically connected to the display structure. The circuit boards need to be bent to the rear side of the display structure. In a frame assembly, the second part of the cover plate, which is positioned opposite the frame, is positioned at an angle and can be understood as follows: In the direction from the rear of the display structure toward the display surface, the distance between the side of the display structure and the second part of the cover plate is greater closer to the display structure. In this way, more bending space for the circuit board can be secured, and a safe clearance for the circuit board can be ensured.

[0051] In possible embodiments, the frame includes a first side and a second side facing each other, the first side being closer to the second portion than the second side. The distance between the first and second sides decreases in the direction from the back of the display structure toward the display surface, the first side is an inclined surface, the second portion is positioned at an angle to the inclined surface, and the distance between the first segment and the reference plane is greater than the distance between the second segment and the reference plane.

[0052] In this example, the frame has a wedge-shaped structure. This allows for greater accommodation space for the curved portion of the circuit board, ensuring safe clearance for the curved portion.

[0053] In possible embodiments, the second portion includes a first end connected to the first portion and a second end opposite to the first end, with both the first and second segments positioned between the first and second ends. The side of the first end facing the frame is attached to the frame.

[0054] In this way, the cover plate is seamlessly connected to the frame when viewed from the outside of the display device, thereby improving the aesthetic appearance of the display device.

[0055] In possible embodiments, the frame assembly further includes an adhesive layer connecting the frame to a second part, and the adhesive layer is located on the side away from the frame and attached to the cover plate.

[0056] Because the adhesive layer is hidden inside, the aesthetic appearance of the display device can be further optimized.

[0057] In possible embodiments, the groove is located at the frame position, opposite to the second portion, and the adhesive layer is located within the groove.

[0058] Because grooves are provided and the adhesive layer is placed within the grooves, the frame size can be further reduced.

[0059] In possible embodiments, the adhesive overflow groove is located on the bottom surface of the groove, opposite to the second portion.

[0060] For example, when manufacturing an adhesive layer using a gel dispensing process, an adhesive overflow groove is used to contain any excess adhesive, reducing the risk of the adhesive flowing to other locations.

[0061] In possible embodiments, the boss is formed on the side of the frame that faces the circuit board. The boss is located away from the frame and in a position where it is attached to the cover plate. The boss is configured to restrict the mounting position of the second portion, with the second end of the second portion resting on the boss.

[0062] By positioning bosses, the mounting position of the cover plate can be restricted. Furthermore, in some cases, the gap between the first portion of the cover plate and the display structure can be adjusted based on different design requirements. For example, if the design gap between the first portion of the cover plate and the display structure is large, the cover plate can be moved upward to widen the gap. Alternatively, if the design gap between the first portion of the cover plate and the display structure is small, the cover plate can be moved downward to narrow the gap. In this way, the fit between the frame assembly (including the frame and cover plate) and the display structure can be improved.

[0063] In possible embodiments, the frame includes a mating portion opposite to the second portion, and further includes an elongated portion connected to the mating portion, the elongated portion projecting from the second portion.

[0064] When a cover plate is installed, it can be adjusted up and down along the frame, and the side of the cover plate facing the circuit board does not extend beyond the side of the frame. In this way, the circuit board can be protected when adjusting the cover plate, and the possibility of the circuit board being damaged by the movable cover plate is reduced.

[0065] In possible embodiments, a protective layer is provided on the side of the second portion that faces the circuit board, and / or on the side of the elongated component that faces the circuit board.

[0066] A protective layer can be used to protect the circuit board.

[0067] In possible embodiments, the frame is the lower frame of the display device.

[0068] In yet another embodiment, the present invention provides a frame assembly which can be used in a display module.

[0069] The frame assembly includes a frame and a cover plate. The frame is configured to be positioned around the display structure of the display device. The cover plate includes a first and second connecting part, the first part being configured to be positioned on the side of the display surface of the display structure, and the second part being positioned on the opposite side of the frame, and the second part including a first segment, a second segment, and a connecting segment connecting the first and second segments, with space formed between the first segment and the reference plane and between the second segment and the reference plane to avoid mechanical parts within the display device. A first concave cavity is formed at the position of the first segment of the cover plate, and the distance between the first segment and the reference plane is greater than the distance between the second segment and the reference plane. The plane perpendicular to the display surface of the display structure is the reference plane.

[0070] The frame assembly is used in display devices. The display device may include a circuit board electrically connected to the display structure. The circuit board needs to be bent to the rear side of the display structure. The first concave cavity is positioned opposite the bent portion of the circuit board, accommodating the bent portion and thereby providing greater space for the bent portion and ensuring safe clearance for the bent portion.

[0071] In possible embodiments, a second recessed cavity is formed at a position on the frame corresponding to the first segment, and the first segment is located within the second recessed cavity.

[0072] In possible embodiments, the frame assembly further includes an adhesive layer which connects the second segment to the frame.

[0073] In possible embodiments, a protective layer is provided on the side of the second segment that faces the circuit board.

[0074] A protective layer may be used to protect the circuit board.

[0075] In possible embodiments, the frame is the lower frame. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0078] One embodiment of the present application provides a display device. The display device 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 an in-vehicle display device, etc. In the embodiments of the present application, the specific form of the display device is not particularly limited.

[0079] In some examples, the screen size of the display device may be 14 inches or larger. For example, the display device may be a 50-inch television, or a television or screen with a larger screen size. The television may be a smart, large-screen television.

[0080] Figure 2 is an example of a structural diagram when the display device 100 is a television. The display device 100 includes a display structure 101, and the display structure 101 may include a display. The display may be a liquid crystal display (LCD) panel or a self-emissive display. When the display is a self-emissive display, the display may be, for example, an organic light-emitting diode (OLED) display or a quantum dot light-emitting diode (QLED) display. When the display is a liquid crystal display, the display device 100 may be referred to as a liquid crystal display device. When the display is a self-emissive display, the display device 100 may be referred to as a self-emissive display device.

[0081] Figure 3 is a schematic exploded view of a display device 100 according to one embodiment of the present invention. The display device 100 further includes a frame assembly 102, a backplane 104, and a rear cover 103. The display structure 101 and the rear cover 103 are arranged on both sides of the frame assembly 102. As the framework and carrier of the entire display device, the backplane 104 can mount most of the mechanical and electronic components of the display device, such as a controller, processor, field output integration block, switching power supply block, speaker, and cathode ray tube.

[0082] To meet people's demand for larger screens and achieve smaller frames and a higher screen-to-body ratio, for example, the size d of the lower frame of the frame assembly can be reduced, as shown in Figure 2.

[0083] To reduce the frame size and increase the screen occupancy rate, the present invention provides several feasible structures as described below.

[0084] Figure 4 is a cross-sectional view showing a partial structure of a display device in an example of the present invention. For example, this cross-sectional view may be a cross-sectional view along line AA shown in Figure 3.

[0085] As shown in Figure 4, this example includes a display structure 101, a frame 105, and a cover plate 106. The frame 105 is positioned around the display structure 101. For example, the frame 105 may be the lower frame shown in Figures 2 and 3. The lower frame and the remaining frames (side frames and upper frames, etc.) within the frame assembly surround the display structure 101 and function as the external frame of the display structure 101.

[0086] In some display devices, the material of the lower frame may differ from that of the rest of the frame. For example, in some scenarios, the lower frame needs to be placed on a support surface. Therefore, the mechanical strength of the lower frame needs to be higher than that of the rest of the frame. For example, the lower frame may be made of an aluminum alloy.

[0087] As shown in Figure 4, the cover plate 106 includes a first portion 1061 and a second portion 1062 that are connected. The first portion 1061 is located on the display surface side of the display structure 101, and the second portion 1062 is positioned opposite the frame 105.

[0088] The display structure 101 has a display surface and a back surface, the display surface being the surface on which the user can view the image.

[0089] The first portion 1061 of the cover plate 106 is positioned on the display surface side. The cover plate positioned on the display surface side can protect the display structure. Furthermore, the first portion 1061 of the cover plate 106 may be used as a decorative component.

[0090] The second portion 1062 of the cover plate 106 is located inside the frame 105 and is positioned opposite the frame 105.

[0091] In some examples, the first part 1061 and the second part 1062 may be integrally formed machine parts.

[0092] Alternatively, in some other examples, the first part 1061 and the second part 1062 are two independent mechanical parts. In some cases, the first part 1061 and the second part 1062 may be connected via a connecting structure. For example, the first part 1061 may be fixed to the second part 1062 via an adhesive layer or a screw-in connector.

[0093] As shown in Figure 4, in this example, the frame 105 and the cover plate 106 are two independent mechanical parts. In some other examples, the frame 105 and the cover plate 106 may be a single molded part.

[0094] The materials of the frame 105 and the cover plate 106 may be the same or different. For example, the frame 105 may be made of an aluminum alloy, and the cover plate 106 may be made of stainless steel.

[0095] As shown in Figure 4, in some display devices, a space 107 is provided inside the first portion 1061 and the second portion 1062 of the cover plate 106. The space 107 may house several mechanical components within the display device, such as a circuit board 108 connected to the display structure 101.

[0096] The circuit board 108, which is electrically connected to the display structure 101, needs to transmit the electrical signals of the display structure 101 to the main board of the display device; therefore, the control device on the main board applies control signals to the display device.

[0097] In some examples, the main board of the display device may be located on the backplane. As shown in Figure 4, the circuit board 108 is bent within space 107 and extends away from the back of the display structure 101, and is electrically connected to the main board to enable signal communication between the display structure 101 and the main board.

[0098] Space 107 can also be interpreted as being used to avoid mechanical components (e.g., circuit boards) within the display device. In some structures, for example, when arranging a circuit board, there are design requirements regarding the avoidance space 107. For example, as shown in Figure 4, sufficient space is provided around the bend of the circuit board 108 to ensure the bending radius and safety clearance, to avoid interference with other mechanical components, and to ensure that the performance of the circuit board is not affected.

[0099] To ensure that the avoidance space 107 satisfies this requirement, the second portion 1062 of the cover plate 106 may include a first segment 106A and a second segment 106B, as shown in Figure 5. Spaces for avoiding mechanical components, such as a circuit board 108, are formed between the first segment 106A and the reference plane L, and between the second segment 106B and the reference plane L. The reference plane L is perpendicular to the display surface of the display structure 101.

[0100] Furthermore, the distance S1 between the first segment 106A and the reference plane L is greater than the distance S2 between the second segment 106B and the reference plane L.

[0101] In this example of the present application, the distance S1 between the first segment 106A and the reference plane L can be interpreted as the distance between the reference plane L and the wall surface of the first segment 106A that faces the inside of the display device. The distance S2 between the second segment 106B and the reference plane L can be interpreted as the distance between the reference plane L and the wall surface of the second segment 106B that faces the inside of the display device.

[0102] In some examples, as shown in Figure 5, the space between the first segment 106A and the reference plane L may accommodate a bent portion 108A of the circuit board 108, and the space between the second segment 106B and the reference plane L may accommodate an extended portion 108B of the circuit board 108. The bent portion 108A includes an arc-shaped bent segment of the circuit board, and the extended portion 108B includes at least a portion that extends away from the back surface of the display structure 101.

[0103] Figure 5 schematically shows the bent portion 108A and the extended portion 108B of the circuit board 108. In this example, the bent portion 108A and the extended portion 108B do not absolutely limit the positions of these two parts.

[0104] In this example of the present invention, the bent portion 108A is positioned in the wide space between the first segment 106A and the reference plane L. This allows for sufficient bending space in the bent portion 108A. This ample clearance allows the bent portion 108A to have a large bending radius and a large safety clearance, which prevents interference with other mechanical parts when bending a circuit board or prevents damage between the bent portion 108A and other mechanical parts when using a display device.

[0105] In some structures, the side M of the display structure 101 may be used as the reference plane L, and the side M may be perpendicular to the display surface of the display structure 101.

[0106] In some possible embodiments, the display structure 101 includes a light source, a lower polarizing plate 1011, an upper polarizing plate 1014, a substrate 1012 on which a plurality of thin-film transistors are arranged, and a color filter 1013.

[0107] The light source projects light. The light passes through the lower polarizer 1011, then through the thin-film transistor. Next, the light needs to pass through the color filter 1013 and the upper polarizer 1014.

[0108] In some examples, as shown in Figure 5, the edges of the substrate 1012 on which multiple thin-film transistors are located protrude more than other film layer structures because they need to be bonded (or connected) to the circuit board 108. A bonding region is located at the edge of the substrate 1012 on which multiple thin-film transistors are located, and the circuit board 108 is connected to the bonding region.

[0109] The side surface of the substrate 1012 on which multiple thin-film transistors are arranged can be shown as the reference plane L.

[0110] As shown in Figure 5, the first segment 106A and the second segment 106B, which are included in the second portion 1062 of the cover plate 106, may be arranged in a direction from the display surface toward the back. In other words, the first segment 106A and the second segment 106B are arranged sequentially in a direction from the display surface toward the back.

[0111] In some examples, as shown in Figure 6, 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 in order from the display side toward the back. Alternatively, the first segment 106A, the third segment (106C), and the second segment 106B may be arranged in order from the display side toward the back. Alternatively, as shown in Figure 6, the third segment 106C, the first segment 106A, and the second segment 106B may be arranged in order from the display side toward the back.

[0112] As shown in Figure 6, if the second portion further includes a third segment 106C, the third segment 106C, the first segment 106A, and the second segment 106B may be arranged in order from the display surface toward the back. The distance S3 between the third segment 106C and the reference plane L may be greater than the distance S1 between the first segment 106A and the reference plane L. Alternatively, the first segment 106A, the second segment 106B, and the third segment (106C) may be arranged in order from the display surface toward the back. The distance S3 between the third segment 106C and the reference plane L may be smaller than the distance S2 between the second segment 106B and the reference plane L. For example, the extension portion 108B of the circuit board 108 may continue to extend into the space between the third segment (106C) and the reference plane L.

[0113] As shown in Figure 6, when assembling the display device, the mounting position of the cover plate 106 can be adjusted vertically (for example, in the Z direction in Figure 6). In some structures, the design gap X between the display surface of the display structure 101 and the first part 1061 of the cover plate 106 differs. For example, the design gap X between the display surface of some display structures 101 and the first part 1061 is large, while the design gap X between the display surface of some display structures 101 and the first part 1061 is small.

[0114] In this invention, the position of the cover plate 106 can be adjusted vertically to meet the gap X requirement of different screens and to accommodate different displays.

[0115] To ensure that the distance S1 between the first segment 106A and the reference plane L is greater than the distance S2 between the second segment 106B and the reference plane L, the present invention provides a number of implementable structures.

[0116] Figures 7 and 8 show two different structures of the frame 105 and the cover plate 106.

[0117] In the two different examples in Figures 7 and 8, the angle α between the first part 1061 and the second part 1062 is less than 90°, the first segment 106A and the second segment 106B are consecutive segments of the second part 1062, and the first segment 106A is closer to the first part 1061 than to the second segment 106B.

[0118] In Figures 7 and 8, the following can be understood: In the direction from the display surface toward the back, the second portion 1062 is gradually inclined toward the inside of the display device, and the distance S2 between the second segment 106B and the reference plane L is smaller than the distance S1 between the first segment 106A and the reference plane L.

[0119] Figure 9 is an exploded view of the frame 105 and cover plate 106 in the example shown in Figure 7. The frame 105 has a first side and a second side facing each other. Referring to Figures 9 and 7, the first side is closer to the second portion 1062 of the cover plate 106 than the second side.

[0120] As shown in Figure 9, the distance between the first side and the second side decreases in the direction from the back of the display structure toward the display surface, and the first side is an inclined surface. In addition, the second portion 1062 of the cover plate 106 is positioned at an angle to the first side, and 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.

[0121] In this example, the frame 105 has a wedge-shaped structure, and the width of the part visible to the user is narrow. As shown in Figure 9, the angle α between the first part 1061 and the second part 1062 of the cover plate 106 is less than 90° so that it fits into the wedge-shaped frame 105.

[0122] Furthermore, as shown in Figure 9, the second portion 1062 of the cover plate 106 includes a third side and a fourth side. The third and fourth sides are parallel to each other, or substantially parallel due to factors such as the manufacturing process. The fourth side is closer to the frame 105 than the third side. In other words, the fourth side of the cover plate 106 and the first side of the frame 105 are positioned opposite each other.

[0123] As shown in Figure 7, in a display device, the smaller the distance between the frame 105 and the upper part visible to the user, the smaller the force acting on the frame. In this application, the frame 105 has a wedge-shaped structure, and the wider lower part can support the force acting on the frame. In addition, because the upper part of the frame is narrow, a frame-narrowing effect can be achieved. Therefore, as shown in Figure 7, the present invention not only achieves a narrower overall frame and a high screen-to-body ratio for the display device, but also achieves a frame-narrowing effect, enabling a narrower double frame of the display device and further optimizing the aesthetic appearance.

[0124] Figure 10 is an exploded view of the frame 105 and cover plate 106 in the example shown in Figure 8. In the structure of this embodiment, the distance between the third and fourth sides of the second portion 1062 of the cover plate 106 decreases in the direction from the back of the display structure toward the display surface, the third side becomes an inclined surface, and the distance between the first segment and the reference surface is greater than the distance between the second segment and the reference surface. In other words, in this example, the second portion 1062 of the cover plate 106 has a wedge-shaped structure.

[0125] Furthermore, as shown in Figure 10, the first and second sides of the frame 105 are parallel to each other.

[0126] In the different examples shown in Figures 9 and 10, regardless of whether the frame 105 is designed as a wedge-shaped structure or the second portion 1062 of the cover plate 106 is designed as a wedge-shaped structure, different spacing clearances can be formed between different segments of the second portion 1062 and the reference plane to ensure that the circuit board 108 meets the requirements of the assembly process.

[0127] To improve the aesthetic appearance of the display device and reduce the frame size, a user-visible cover plate portion is attached to the frame portion, as shown in Figures 7 and 8. In some assembly structures, there is a small assembly tolerance between the user-visible cover plate portion and the frame portion, resulting in a small gap. For example, this gap may be 0.125 mm or less.

[0128] Alternatively, it can also be interpreted as follows: As shown in Figure 7, the second portion 1062 of the cover plate 106 includes a first end 1062A connected to the first portion 1061 and a second end 1062B opposite to the first end 1062A. The side of the first end 1062A facing the frame 105 is attached to the frame 105.

[0129] In some examples, both the first segment 106A and the second segment 106B are located between the first end 1062A and the second end 1062B, with the first segment 106A being closer to the first end 1062A than to the second segment 106B.

[0130] To further improve the aesthetic appearance of the display device, Figure 11 is an exploded view of the frame 105 and cover plate 106. The surface of the frame 105 that is attached to the first end of the cover plate 106 is the inclined surface 105A. In the direction from the back of the display structure toward the display surface, the inclined surface 105A of the frame 105 that is attached to the first end is inclined away from the side of the display structure. Alternatively, in the direction from the display surface of the display structure toward the back, the inclined surface 105A can be interpreted as being inclined toward the inside of the display device.

[0131] The surface of the frame 105 that is attached to the first end of the cover plate 106 is designed as an inclined surface. This reduces the visual impact of gaps and improves the aesthetic appearance, as the frame 105 is essentially attached to the cover plate 106 when viewed from the outside of the display device, even with design or assembly tolerances.

[0132] In some examples, when the frame 105 and the cover plate 106 are two independent mechanical parts, the frame 105 and the cover plate 106 may be connected via a connecting structure.

[0133] Figure 12 shows an example of the connection relationship between the frame 105 and the cover plate 106. The second portion 1062 of the cover plate 106 may be connected to the frame 105. For example, the frame 105 may be bonded to the second portion 1062 of the cover plate 106 via an adhesive layer 109.

[0134] In this example of the present invention, the adhesive layer 109 is arranged in a concealed manner. As shown in Figure 12, the adhesive layer 109 is located on the side away from the frame 105 and on the side attached to the cover plate 106. In this way, the adhesive layer 109 is not visible when viewed from the outside of the display device, further optimizing the aesthetic appearance of the display device.

[0135] As shown in Figure 13, in order to reduce the frame size of the display device and increase the screen-to-body ratio, in some structures the groove 105B may be located at the position of the frame 105 and opposite the second portion 1062 of the cover plate 106, and the adhesive layer 109 may be placed in this groove 105B. Alternatively, the groove may be located at the second portion 1062 of the cover plate 106, and the adhesive layer 109 may be placed in this groove of the cover plate.

[0136] In some examples, the adhesive layer 109 can be manufactured using an adhesive process. For example, the cover plate 106 and the frame 105 can be joined via double-sided tape. In this way, manufacturing costs can be further reduced. Alternatively, in some other examples, the adhesive layer 109 can be manufactured using an adhesive coating process.

[0137] In a feasible process, as shown in Figure 13, an adhesive overflow groove 110 is located on the bottom surface of groove 105B, opposite to the second portion 1062, to prevent the liquid adhesive from overflowing from groove 105B.

[0138] Multiple adhesive overflow grooves 110 may be provided, and these multiple adhesive overflow grooves 110 may be spaced apart from each other in the direction of extension of groove 105B. For example, in Figure 13, two adhesive overflow grooves 110 are provided.

[0139] The shape and size of the adhesive overflow groove 110 are not particularly limited in this application, and for example, an arc-shaped groove or a rectangular groove may be used.

[0140] In some processes, for example, when the cover plate 106 and frame 105 are joined by double-sided tape, the thickness of the double-sided tape is greater than the depth of the groove 105B. After pressurization and compression of the adhesive layer, it is ensured that the exposed portion of the cover plate 106 adheres tightly to the exposed portion of the frame 105, improving the aesthetic appearance of the display device.

[0141] Furthermore, as shown in Figure 13, the boss 111 is formed on the side of the frame 105 that faces the inside of the display device, and the second end of the second portion 1062 of the cover plate 106 is located above the boss 111. The boss 111 can be used to restrict the lower limit position of the cover plate 106 during installation. This prevents damage to some components inside the display device due to, for example, a large misalignment of the cover plate 106 during installation, thereby reducing the risk of damage to the circuit board.

[0142] As shown in Figure 14, in some examples, the frame 105 includes not only a mating portion 1051 facing the cover plate 106, but also an elongated portion 1052 connected to the mating portion 1051. The elongated portion 1052 may be connected to other mechanical parts, for example, to the back cover of a display device. The side P of the elongated portion 1052 that faces the inside of the display device protrudes more than the third side of the second portion 1062 of the cover plate 106 that faces the inside of the display device.

[0143] For example, the avoidance space in this example of the present invention is for avoiding the mounting space of the circuit board 108. The circuit board 108 is susceptible to scratches from surrounding mechanical parts. Therefore, in the example of Figure 14, the circuit board 108 may be connected to the back cover of the display device, and the side of the elongated portion 1052 that faces the inside of the display device protrudes more than the side of the second portion 1062 of the cover plate 106 that faces the inside of the display device. In this way, the circuit board 108 may be less susceptible to scratches from the high-hardness cover plate 106 or frame 105.

[0144] As shown in Figure 14, in this example, the side surface P of the elongated portion 1052 is a vertical surface. In some other examples, the side surface P of the elongated portion 1052 may instead be an inclined surface.

[0145] To further protect the circuit board 108, the protective layer 112 may be placed on the side of the second portion 1062 of the cover plate 106 that faces the inside of the display device, as shown in Figure 15. Alternatively, the protective layer 112 may be placed on the side of the elongated portion 1052 of the frame 105 that faces the inside of the display device. Alternatively, the protective layer 112 may be placed on the side of the second portion 1062 of the cover plate 106 that faces the inside of the display device, and the protective layer 112 may be placed on the side of the elongated portion 1052 of the frame 105 that faces the inside of the display device.

[0146] The protective layer 112 can be used to reduce the risk of damage to the circuit board 108 by the cover plate or frame and to improve the yield of display devices.

[0147] The protective layer 112 may be made from at least one of several materials, such as Mylar, foam, or rubber strips.

[0148] Figures 16 and 17 show the structure of another embodiment of a display device according to one embodiment of the present invention, which allows for space to be provided to avoid mechanical components (e.g., a circuit board 108). In this example, a frame 105 and a cover plate 106 are included, the cover plate 106 including a first portion 1061 and a second portion 1062 that are connected. The first portion 1061 is located on the display surface side of the display structure 101, and the second portion 1062 is positioned opposite the frame 105.

[0149] There is a space 107 between the first part 1061 and the second part 1062 of the cover plate 106, and a mechanical component such as a circuit board 108 can be accommodated in this space 107.

[0150] As shown in Figure 17, 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, which connects the first segment 106A and the second segment 106B.

[0151] In the example shown in Figure 17, the first segment 106A is closer to the first portion 1061 of the cover plate than the second segment 106B. A first concave cavity 113 is formed at the position of the first segment 106A of the cover plate 106, and this concave cavity can be used to expand the space 107, so that the distance S1 between the first segment 106A and the reference plane L is greater than the distance S2 between the second segment 106B and the reference plane L. In this example, the reference plane L is a plane perpendicular to the display surface of the display structure 101.

[0152] For an explanation of the reference plane L in this example, please refer to the reference plane L in the previously mentioned example.

[0153] In this embodiment, the distance S1 between the first segment 106A and the reference surface L can be interpreted as the distance between the reference surface L and the surface of the first concave cavity 113 that faces the inside of the display device. The distance S2 between the second segment 106B and the reference surface L can be interpreted as the distance between the reference surface L and the surface of the second segment 106B that faces the inside of the display device.

[0154] As shown in Figure 17, the distance between the first segment 106A and the reference plane L can provide space to avoid the bent portion 108A of the circuit board 108, and the distance between the second segment 106B and the reference plane L can provide space to avoid the extended portion 108B of the circuit board 108.

[0155] By positioning the concave cavity at the location of the first segment 106A, a large space is provided between the first segment 106A and the reference plane L. In this way, sufficient bending space can be provided in the circuit board 108, and it can be ensured that the bending space meets the safety clearance requirements.

[0156] In some examples, the space between the second segment 106B and the reference plane L can avoid at least a portion of the extended portion 108B of the circuit board 108.

[0157] Refer to Figure 17. The second recessed cavity 114 is formed at the position of the frame 105 and corresponding to the first segment 106A, and the first segment 106A is located within the second recessed cavity 114.

[0158] As shown in Figure 17, the second concave cavity 114 is positioned on the frame 105, so the width of the user-visible portion of the frame 105 is narrowed. In this way, the frame can achieve a frame-narrowing effect. Therefore, as shown in Figure 17, the present invention not only achieves a narrower frame and a high screen-to-body ratio for the entire display device, but also achieves a frame-narrowing effect for the frame itself, thereby achieving a narrower double frame for the display device and further optimizing its appearance and aesthetics.

[0159] Figure 18 is a schematic exploded view of the frame 105 and the cover plate 106. In this example, the height h1 of the second concave cavity 114 located on the frame 105 is greater than the height h2 of the first segment 106A of the cover plate 106.

[0160] In this way, when attaching the cover plate 106, the mounting position of the cover plate 106 can be adjusted vertically to meet the gap X requirements of different screens and to accommodate different displays.

[0161] The height h1 of the second concave cavity 114 and the height h2 of the first segment 106A can be interpreted as dimensions in a direction perpendicular to the display surface of the display structure, or as dimensions in a direction parallel to the reference plane L.

[0162] In the examples shown in Figures 16 and 17, the second segment 106B of the cover plate 106 may be connected to the frame 105 via an adhesive layer 109. In this way, a hidden connection structure is used in this example, which is not visible to the user, thus improving the aesthetic appearance.

[0163] In some examples, the groove may be located on the frame 105, opposite the second segment 106B, and the adhesive layer 109 may be placed in this groove. Alternatively, the groove may be located on the second segment 106B of the cover plate 106, and the adhesive layer 109 may be placed in this groove.

[0164] In some other examples, the frame 105 and the cover plate 106 may instead be a single integrated structure.

[0165] To protect the circuit board 108, a protective layer may be placed on the side of the second segment 106B of the cover plate 106 that faces the circuit board 108. Alternatively, a protective layer may also be placed on the side of the frame 105 that faces the circuit board 108.

[0166] The protective layer may be made from multiple materials, for example, at least one of Mylar, foam, or rubber strips. When the protective layer is made from Mylar, it is thin and does not occupy a large space.

[0167] As shown in Figure 17, the display device in this example of the present invention may further include a light source and an optical structure for processing the light from the light source. The light emitted from the light source is processed by the optical structure and then projected to the user through the display structure 101 to display an image.

[0168] For example, the optical structure may be a reflector 117, a diffuser 116, a light-enhancing sheet 115, or a prism, or a combination thereof. The main function of the optical structure is to improve the display effect by completely diffusing or focusing the light passing through the optical structure, increasing the light utilization rate, and turning a point light source into a surface light source.

[0169] The backplane 104, which is used as the support frame for the entire display device, may be configured to support the optical structure.

[0170] The above describes several possible design solutions in this application with reference to the attached drawings. In some other possible examples covered in this application, multiple mechanical components that need to be avoided may instead be included inside the display. In this case, by using a multi-segment avoidance design, referencing similar solutions provided in this application, it is possible to provide avoidance space for each of the multiple mechanical components, thereby achieving a narrower frame design for the display device while ensuring safe clearance space for the multiple mechanical components.

[0171] In this specification, specific features, structures, materials, or properties may be combined as appropriate in one or more embodiments or examples.

[0172] The above description is merely a specific embodiment of the present application and is not intended to limit the scope of protection of the present application. Any modification or substitution that can be easily conceived by a person skilled in the art within the technical scope disclosed herein shall be included in the scope of protection of the present application. Accordingly, the scope of protection of the present application shall be subject to the scope of protection of the claims.
