Description

Technical Field

[0001] This invention relates to the field of display technology, and in particular to a display device. Background Technology

[0002] With the development of display technology, display devices have become extremely popular and widely used. As living standards improve, people's requirements for the appearance of display devices are also getting higher and higher.

[0003] In pursuit of product diversity and aesthetics, the industry is experimenting with various solutions. For example, designing the corners of display devices with chamfers, such as rounded corners, can give a thinner and more aesthetically pleasing appearance. Existing chamfered display devices include: a display panel, a backlight module, and a front shell located below the bottom of the display panel. The backlight module includes a back plate, a frame, and a middle frame located on the sides and top of the display panel. The back panel is located on one side of the back of the display panel. The middle frame is used to fix and cover the side and top of the display panel. The front shell is used to cover the bottom of the display panel and the circuit board connected to the bottom and corners of the display panel. For fixing the display device at non-corner positions, the middle frame is fixed to the back panel, and the front shell is fixed to the back panel through the display panel, the frame, etc. For fixing the corner positions of the display device, the end of the middle frame can still be fixed to the back panel. However, the frame cannot be set at the corner positions because the circuit board is connected to the corner of the display panel and there is a gradually widening gap between the corner of the display panel and the frame. Therefore, the corner portion of the front shell is overlapped with the end of the middle frame and fixed together.

[0004] However, in the above solution, the front shell end overlaps with the middle frame end, which results in insufficient connection strength at the corner of the display device. If the display device is accidentally dropped or subjected to external impact, the corner of the display device is easily damaged. Summary of the Invention

[0005] This invention provides a rounded corner display device.

[0006] The rounded corner display device provided by the present invention can improve the connection strength at the corner of the display device, making the corner of the display device less prone to damage.

[0007] This invention provides a display device, comprising: a display panel, the front side of which is used to display an image; a backlight module, which provides a backlight source for the display panel, the backlight module including a middle frame, the middle frame including a side portion, the side end of the display panel being fixed to the side portion; a front shell, which covers the bottom side of the display panel, and the corners of the display device having chamfered structures, wherein at positions corresponding to the chamfered structures, an adapter connects the end of the side portion and the end of the front shell, thus providing a rounded corner display device.

[0008] By connecting the end of the side panel to the end of the front panel via an adapter, in other words, the end of the front panel is connected to the end of the middle frame via the adapter, while the end of the middle frame is directly connected to the back panel. This allows the end of the front panel to be indirectly fixed to the back panel, thereby increasing the connection strength at the corners. Even if the display device is accidentally dropped or subjected to external impact, the corners of the display device are less likely to be damaged, thus improving the reliability of the display device.

[0009] The structure of the present invention, as well as its other inventive objects and beneficial effects, will become more apparent from the description of preferred embodiments taken in conjunction with the accompanying drawings. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Display devices with chamfered corners generally suffer from insufficient connection strength at the corner locations. For example, this will be illustrated using a display device with rounded corners. Figure 1 This is a schematic diagram of the internal structure of a display device based on related technologies. Figure 1 Since the left and right corners of the display device 80 have similar structures, only the connection structure at the left corner of the display device 80 is shown in the illustration. Furthermore, the portion of the front cover 83 that obstructs the front of the display panel 82 is removed to facilitate observation of the internal structure of the display device 80.

[0026] Referring to the figure, the related display device 80 includes a middle frame 81, a display panel 82, a front shell 83, and a first circuit board 84. The left end, top end, and right end of the display panel 82 are fixed to the middle frame 81, the middle frame 81 is fixed to the back plate, and the lower end of the display panel 82 is fixed to the back plate by a plastic frame.

[0027] The corner structure of the display panel 82 is also a rounded chamfer structure. Since the lower end of the display panel 82 is connected to the first circuit board 84, there is a gap between the bottom end of the front shell 83 and the bottom end of the display panel 82. Therefore, in order to smoothly transition with the front shell 83, the bending radius of the end of the middle frame 81 must gradually increase. As a result, there is a gradually widening gap 85 between the inner sidewall of the middle frame 81 and the corner of the display panel 82.

[0028] Corresponding to the corner positions of the display panel 82, the end of the mid-frame 81 can be fixed to the back panel. However, a frame cannot be installed at the corresponding position of the end of the front shell 83 because if a frame is installed at this position, it will be located within the aforementioned widening gap 85, making the width of the widening gap 85 more difficult to control. Therefore, it is possible to consider overlapping the end of the front shell 83 with the end of the mid-frame 81, but this would result in a relatively obvious step 86 at the junction of the mid-frame 81 and the front shell 83.

[0029] The above solution presents the following problems: First, the overlap of the front shell 83 with the end of the mid-frame 81 results in insufficient connection strength at the corners of the display device 80. Second, due to the aforementioned widening gap 85 on the inner side of the mid-frame 81, the corners of the display panel 82 cannot be fixed to the mid-frame 81, thus failing to provide support for the corners of the display panel 82. Finally, the overlap of the front shell 83 with the end of the mid-frame 81 creates a stepped section 86 at the junction of the front shell 83 and the mid-frame 81, which affects the aesthetics of the display device 80.

[0030] This invention was proposed to solve the above-mentioned problems.

[0031] Example

[0032] Figure 2 This is a schematic diagram of the disassembled structure of a display device provided in an embodiment of the present invention. In the present invention, the display device 100 can be a television, monitor, mobile phone, tablet computer, or laptop computer, etc. This application takes an LCD television as an example for illustration. Other types of display devices are similar and will not be described in detail here.

[0033] like Figure 2 As shown, the display device 100 includes: a display panel 10, a backlight module 20, a front shell 50, and an adapter 60; the backlight module 20 includes a middle frame 30.

[0034] The display device 100 also includes a rear cover, and the backlight module 20 also includes an optical film 21, a diffuser 22, a reflector 23, a light strip 24, and a back plate 25.

[0035] The display panel 10 has a front side for displaying images, a backlight module 20 for providing a backlight for the display panel 10, a mid-frame 30 including a side portion 31, and the side end of the display panel 10 is fixed to the side portion 31; a front shell 50 covers the bottom side of the display panel 10, and the bottom end of the front shell 50 is spaced from the bottom end of the display panel 10; at least a portion of the structure of the adapter 60 is located in the space, and the corner of the display device 100 has a chamfered structure. At the position corresponding to the chamfered structure, the adapter 60 connects the end portion 311 of the side portion and the end portion 501 of the front shell.

[0036] By connecting the end 311 of the side portion and the end 501 of the front housing with the adapter 60, in other words, the end of the front housing 50 is connected to the end of the middle frame 30 through the adapter 60, while the end of the middle frame 30 is directly connected to the back plate 25. This allows the end of the front housing 50 to be indirectly fixed to the back plate 25, thereby improving the connection strength at the corner position. Even if the display device 100 is accidentally dropped or subjected to external impact, the corner of the display device 100 is not easily damaged, thus improving the reliability of the display device 100.

[0037] The structure and function of each part are described in detail below.

[0038] Figure 3 This is a schematic diagram of the structure of the display panel in the display device provided in an embodiment of the present invention, with reference to... Figure 3 As shown, the front side of the display panel 10 is used to display images. In this application, the display panel 10 may be, for example, a liquid crystal display panel. Furthermore, the corners of the display device in this application have a chamfered structure, and the corners of the display panel 10 also have a chamfered structure to cooperate with this chamfered structure.

[0039] like Figure 3 As shown, the front of the display panel 10 includes a display area 101 for display and a black matrix area 102 surrounding the display area 101. The black matrix area 102 is used to arrange metal lines, etc. Generally, the width of the black matrix area 102 located at the bottom of the display panel 10 is greater than that at the top and sides. In addition, a circuit board, such as a chip-on-flex (COF) film, is also provided at the bottom of the display panel 10.

[0040] Reference Figure 2 As shown, the backlight module 20 provides a backlight source for the display panel 10. According to the position of the light strip 24, the backlight module 20 can be divided into a direct-lit backlight module and an edge-lit backlight module. In this invention, the backlight module 20 is a direct-lit backlight module as an example for explanation.

[0041] The backlight module 20 includes a mid-frame 30, the mid-frame 30 includes a side portion 31, and the side end of the display panel 10 is fixed to the side portion 31. Figure 2In the example shown, the middle frame 30 has two sides 31, left and right, which can be used to fix the left and right ends of the display panel 10, respectively; furthermore, the middle frame 30 also has a top 32, which can be used to fix the top of the display panel 10. It should be understood that the middle frame 30 in this invention is not only used to fix the display panel 10, but can also be used to cover the top and sides of the display panel 10.

[0042] The backlight module 20 also includes an optical film 21, a diffuser plate 22, a reflector 23, an LED strip 24, and a backplate 25, which are fixed in sequence. The light emitted by the LED strip 24 is fully scattered after passing through the diffuser plate 22. The reflector 23 is used to ensure that the light emitted by the LED strip 24 enters the diffuser plate as much as possible. The light scattered by the diffuser plate 22 passes through the optical film 21, which can convert the point light source array into a surface light source with uniform brightness, and then illuminate the display panel 10.

[0043] Furthermore, Figure 4 This is a longitudinal sectional view of the display device provided in an embodiment of the present invention, with reference to... Figure 4 As shown, the front cover 50 covers the bottom side of the display panel 10. Specifically, the front cover 50 blocks the bottom side of the display panel 10, and there is a gap H between the bottom end of the front cover 50 and the bottom end of the display panel 10. The gap H can be used to accommodate the flip-chip film 11 at the bottom end of the display panel 10, or it can be used to accommodate other structural components as needed.

[0044] Figure 4 In the middle, part of the front shell 50 is bonded to the bottom edge of the display panel 10, the bottom edge of the display panel 10 is fixed to the frame 26, and the frame 26 is fixed to the back plate 25.

[0045] Figure 5 This is a schematic diagram of the internal structure of the display device provided in an embodiment of the present invention, with reference to... Figure 5 As shown, the adapter 60 is indicated by dashed lines. At least a portion of the structure of the adapter 60 is located within the interval H. The corner 70 of the display device has a chamfered structure. At a position corresponding to the chamfered structure, the adapter 60 connects the end 311 of the side portion and the end 501 of the front housing. Furthermore, the chamfered structure can include a rounded chamfer, a square chamfer, or a chamfer of arbitrary curves, etc. Figure 5 In the example shown, the chamfer of the corner 70 of the display section is a smooth curved chamfer with a gradually increasing radius. In this application, the chamfer of the corner 70 of the display panel is, for example, a rounded chamfer.

[0046] In some embodiments, the ends of the front shell 50 and the side portion 31 corresponding to the corners of the display device 100 are both bent ends and have complementary shapes, so that the outer contour of the junction of the side portion 31 and the front shell 50 is a continuous curved surface.

[0047] Figure 5The diagram shows the structure in which the end faces of the front shell 50 and the side portion 31 fit together, which gives the corners of the display device 100 a smooth, rounded surface effect, making the display device 100 more aesthetically pleasing.

[0048] It should be understood that, Figure 5 In order to facilitate the connection between the end 311 of the side portion and the end 501 of the front shell, the adapter 60 is located at a position close to the corner 70 of the display device in the interval H. However, the present invention is not limited to this and can also be located at a position farther away from the corner of the display device 100.

[0049] In the accompanying drawings of this application embodiment, to facilitate the description of the relative positions between the various components, the directions are defined as follows: the direction from the edge of the display panel 10 toward the middle portion of the display panel 10 is inward, and the direction from the middle portion of the display panel 10 toward the edge of the display panel 10 is outward. Furthermore, the direction from the front of the display panel 10 toward the back of the display panel 10 is rearward, and the direction from the back of the display panel 10 toward the front of the display panel 10 is forward.

[0050] Figure 6 This is a three-dimensional structural diagram of the adapter in the display device provided in an embodiment of the present invention, with reference to... Figure 5 , Figure 6 As shown, the adapter 60 includes an inwardly extending bearing surface 61, and the corner of the display panel 10 is fixed to the bearing surface 61.

[0051] When the corner of the display device 100 has a chamfered structure, the display panel 10 also has a corresponding chamfered structure at its corner. This results in a gradually widening gap between the corner of the display device 100 and the corner of the display panel 10. Therefore, the related technology has the problem that it is impossible to support the corner of the display panel 10. However, by providing a bearing surface 61 on the adapter 60, the corner of the display panel 10 can be fixed on the bearing surface 61.

[0052] There are various ways in which the bearing surface 61 can be formed. For example, the adapter 60 may include an inwardly extending bearing portion 62, and the front side of the bearing portion may be the bearing surface 61. Alternatively, the adapter 60 may include multiple inwardly extending bearing platforms, which are spaced apart from each other, and the bearing surface 61 is formed by the front surface of the multiple bearing platforms, etc. Such variations are all included within the scope of this application.

[0053] The following explains how to fix the adapter 60 and the middle frame 30. Figure 7 This is a schematic diagram of the structure of the display device provided in the embodiment of the present invention, showing the cooperation between the middle frame and the adapter. Figure 6 , Figure 7As shown, the side portion 31 includes a first fixing section 312, which corresponds to the corner of the display panel 10. The first fixing section 312 includes a rearwardly facing first fixing surface 313. The adapter 60 has a forward-facing positioning surface 62 corresponding to the first fixing surface 313. The first fixing surface 313 and the positioning surface 62 overlap and are fixed together. Specifically, the first fixing section 312 corresponds to the corner of the display panel 10, meaning that the first fixing section 312 is located on the side of the corner of the display panel 10.

[0054] As described above, by overlapping and fixing the rearward-facing first fixing surface 313 and the frontward-facing positioning surface 62, it is equivalent to attaching the adapter 60 from the rear to the first fixing section 312, so as to prevent the adapter 60 from protruding from the front side of the middle frame 30 and affecting the external aesthetics of the display device 100.

[0055] Alternatively, multiple guide posts, such as two, can be provided on the positioning surface 62, and guide holes can be provided on the first fixing surface 313 to cooperate with the guide posts 508. This can ensure that the relative position of the first fixing end and the adapter 60 is relatively accurate.

[0056] Furthermore, in order to ensure that the side panel 31 and the adapter 60 can simultaneously fix the display panel 10, refer to Figure 6 , Figure 7 As shown, the side portion 31 also includes a second fixing section 314 connected to the first fixing section 312. The second fixing section 314 includes an inwardly extending second fixing surface 315, and at least a portion of the structure of the side end of the panel is fixed to the second fixing surface 315.

[0057] like Figure 6 , Figure 7 The bearing surface 61 is shown to face forward and is higher than the positioning surface 62 in the front-back direction, so that the second fixing surface 315 and the bearing surface 61 are located in the same plane.

[0058] By making the bearing surface 61 higher than the positioning surface 62 in the front-back direction, the second fixing surface 315 and the bearing surface 61 are located in the same plane. This allows the straight and corner portions of the display panel 10 to be fixed on the second fixing surface 315 and the bearing surface 61 respectively, thereby improving the fixation reliability of the adapter 60 and the middle frame 30.

[0059] The second fixed segment 314 and the first fixed segment 312 are two adjacent parts on the side 31. Figure 8 This is a three-dimensional structural diagram of the interaction between the second fixing section and the display panel in the display device provided in an embodiment of the present invention. Furthermore, regarding the formation of the second fixing surface 315, refer to... Figure 8As shown, the second fixing segment 314 may include an inwardly extending second fixing part 317, and the front side of the second fixing part 317 is a second fixing surface 315. The display panel 10 can be glued to the second fixing surface 315.

[0060] in addition, Figure 9 This is a three-dimensional structural diagram of the cooperation between the middle frame and the adapter in the display device provided in an embodiment of the present invention, with reference to... Figure 8 , Figure 9 As shown, the ends of the bearing portion 63 near the second fixing portion 317 and the ends of the second fixing portion 317 near the bearing portion 63 can overlap and fix each other. This makes the fixing of the adapter 60 and the middle frame 30 more reliable.

[0061] This is because, based on fixing the positioning surface 62 of the adapter 60 and the first fixing surface 313 of the first fixing section 312, the adapter 60 is supported at another position, so that the second fixing section 314 can also play an auxiliary role in fixing the adapter 60.

[0062] It should be understood that, with reference Figure 7 As shown, in order to improve the fixing effect of the second fixing part 317 on the adapter 60, the end of the second fixing surface 315 can be positioned above the end of the bearing surface 61.

[0063] Reference Figure 7 , Figure 9 As shown, a sealing boss 316 is provided on the second fixing surface 315. The sealing boss 316 extends to the front side of the bearing portion 63 and overlaps with the corresponding area on the bearing surface 61. The corresponding area here is, for example, a projection area generated by projecting the sealing boss 316 onto the adapter 60, and the end of the sealing boss 316 can overlap with the projection area on the adapter 60.

[0064] When the display panel 10 is fixed to the second fixing part with adhesive, the adhesive-blocking boss 316 can prevent adhesive overflow, or it can be used to assist in the positioning of the tape. The adhesive-blocking boss 316 extends to the front side of the support part and overlaps with the support part, which can further improve the fixation and reliability of the adapter 60 and the middle frame 30.

[0065] The following describes the mating structure of the front shell 50, the adapter 60, and the display panel 10.

[0066] Figure 10 This is a schematic diagram of the front shell structure in the display device provided in an embodiment of the present invention, with reference to... Figure 5 , Figure 6 , Figure 10 As shown, the end 502 of the front housing 50 near the side 31 and the adapter 60 are detachably connected.

[0067] For example, a connecting hole 502 can be provided at the end 501 of the front housing, and an internal threaded hole 503 can be provided at the corresponding position of the adapter 60. The end 501 of the front housing and the internal threaded hole 503 can be aligned and connected together using fasteners such as screws.

[0068] In addition, a circuit board, such as COF 11, is connected to the bottom of the display panel 10.

[0069] Figure 11 This is a top view of the display device provided in an embodiment of the present invention, with reference to... Figure 4 , Figure 11 As shown, the front housing 50 includes:

[0070] The main body 500 is located on the outer side of the bottom end of the COF and shields the display panel 10 and the COF on the bottom side; the width of the main body 500 in the inward and outward directions is the same as the width of the side portion 31 in the inward and outward directions; furthermore, the main body 500 and the side portion 31 can also be made of the same material; and

[0071] The shielding part 504 extends inward to shield the bottom of the display panel 10 and the flip film 11 on the front side. Furthermore, the shielding part 504 and the main body part 500 are made of different materials.

[0072] Since the width of the main body 500 in the inward and outward directions is the same as the width of the side 31 in the inward and outward directions, the main body 500 and the side 31 are made of the same material, while the shielding part 504 and the main body 500 are made of different materials, so that the middle frame 30 and the front shell 50 can have the effect of visually equal width.

[0073] Furthermore, as previously mentioned, there is a gradually widening gap 85 between the inner side 31 of the first fixing segment 312 and the display panel 10, referring to... Figure 10 As shown, the shielding portion 504 can have an extension 505, which is positioned on the front side of the gap 85, thus allowing the front cover 50 to shield the gradually widening gap 85. (Refer to...) Figure 9 As shown, in order to support the extension 505, a protruding support portion 509 may be provided on the front side of the adapter 60.

[0074] In addition, refer to Figure 6 , Figure 10 As shown, the extension 505 also has an insertion portion 506 extending rearward, and an insertion notch 64 is provided on the adapter 60 accordingly. When the extension 505 extends above the adapter 60, the insertion portion 506 is inserted into the insertion notch 64, which can assist in positioning the front shell 50.

[0075] Furthermore, referring to Figure 6 A threaded hole 65 can be provided on the adapter 60, and the adapter 60 can be fixed to the back plate 25 by passing screws through the threaded hole.

[0076] Figure 12 This is a rear schematic diagram of the adapter in the display device provided in an embodiment of the present invention, with reference to... Figure 12 As shown, it can be understood that in order to enable the adapter 60 and the back plate 25 to be positioned relatively accurately, a positioning post 507 is provided on the rear end face of the adapter 60, and a positioning hole is provided at the corresponding position on the back plate 25. In this way, when installing the connector, it is only necessary to insert the positioning post 507 into the positioning hole and then use fasteners to fix the back plate 25 and the adapter 60 together.

[0077] In this embodiment, the display device 100 includes: a display panel 10, the front of which is used to display an image; a backlight module 20, which provides a backlight source for the display panel 10, the backlight module 20 including a middle frame 30, the middle frame 30 including a side portion 31, the side end of the display panel 10 being fixed to the side portion 31; a front shell 50, which covers the bottom side of the display panel 10, and the bottom end of the front shell 50 is spaced from the bottom end of the display panel 10; and an adapter 60, which is located in the space, the corner of the display device 100 having a chamfered structure, and at a position corresponding to the chamfered structure, the adapter 60 connects the end portion 311 of the side portion and the end portion 501 of the front shell. By connecting the end 311 of the side portion and the end 501 of the front housing with the adapter 60, in other words, the end of the front housing is connected to the end of the middle frame 30 through the adapter 60, and the end of the middle frame 30 is directly connected to the back plate 25. This allows the end of the front frame to be indirectly fixed to the back plate 25, thereby improving the connection strength at the corner position. Even if the display device 100 is accidentally dropped or subjected to external impact, the corner of the display device 100 is not easily damaged, thus improving the reliability of the display device 100.
