Description

Technical Field

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

[0002] Display devices are used in vehicles, homes, and other settings to display images or information. As technology advances, users want display devices with increasingly narrower bezels to increase screen-to-body ratio, but current technology often cannot meet this requirement. Utility Model Content

[0003] This application provides a display device for solving the problem of how to reduce the bezel width of the display device and increase the screen-to-body ratio.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] This application provides a display device including a mid-frame and a back cover. The mid-frame supports the screen and backlight assembly. The back cover includes a side frame portion with a groove on its inner side, and the mid-frame includes a mounting portion that is mounted in the groove.

[0006] In this way, compared to the solution of fixing the outer edge of the middle frame to the end face of the side frame facing the light-transmitting cover, installing the mounting part of the middle frame in the groove on the inner side of the side frame can avoid the middle frame affecting the installation space of the screen in the plane where the display surface is located. This allows the screen size to be limited only by the side frame, thus increasing the screen size and making the screen size compatible with the size of the space enclosed by the side frame. This reduces the width of the black border on the light-transmitting cover, reduces the bezel width, and increases the screen-to-body ratio.

[0007] In some embodiments, the mid-frame includes a flat panel portion, and a mounting portion is disposed on the outer edge of the flat panel portion. The flat panel portion is used to support the screen and the backlight assembly.

[0008] In some embodiments, the mounting portion is plate-shaped, and the mounting portion is perpendicular to or intersects with the plate portion.

[0010] In some embodiments, the middle frame includes a first middle frame portion and a second middle frame portion arranged circumferentially along the side frame portion, wherein the length direction of the first middle frame portion is perpendicular to the length direction of the second middle frame portion.

[0011] In some embodiments, there are multiple middle frames and multiple grooves. The multiple middle frames and multiple grooves are arranged circumferentially along the side frame portion. Each middle frame includes a mounting portion, and the mounting portions of the multiple middle frames are respectively mounted in the multiple grooves.

[0012] In some embodiments, the side frame portion includes a first side frame portion and a second side frame portion opposite to each other, and a third side frame portion and a fourth side frame portion connected between the first side frame portion and the second side frame portion;

[0013] The multiple grooves include a first groove, a second groove, a third groove, and a fourth groove;

[0014] The first groove is provided on the inner side surface of the first side frame and the third side frame; the second groove is provided on the inner side surface of the third side frame and the second side frame; the third groove is provided on the inner side surface of the second side frame and the fourth side frame; and the fourth groove is provided on the inner side surface of the fourth side frame and the first side frame.

[0015] The multiple middle frames include a first middle frame, a second middle frame, a third middle frame, and a fourth middle frame. The mounting part of the first middle frame is installed in a first groove, the mounting part of the second middle frame is installed in a second groove, the mounting part of the third middle frame is installed in a third groove, and the mounting part of the fourth middle frame is installed in a fourth groove.

[0035] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a display device 100 provided for related technologies. The display device 100 can be used to display images and information, and can be applied to the center console of a vehicle, the back of a seat, or other scenarios, which are not limited in this application.

[0036] Please see Figure 2 , Figure 2 This is a schematic cross-sectional view of the display device 100 shown in Figure 1 along line AA. The display device 100 may include a mid-frame 10, a back cover 20, a screen 30, a backlight assembly 40, and a light-transmitting cover 50 (see Figure 1). Figure 1 ).

[0037] The back cover 20 includes a side frame portion 21 and a back plate portion 22 connected to the side frame portion 21, with the side frame portion 21 and the back plate portion 22 forming an accommodating groove 23.

[0038] The screen 30 and the backlight assembly 40 are located within the aforementioned receiving slot 23, with the screen 30 situated on the side of the backlight assembly 40 opposite to the back panel 22. The backlight module 40 generates backlight, and the screen 30 modulates the backlight generated by the backlight module 40 to generate a display image, which is displayed on the surface of the screen 30 opposite to the backlight module 40 for viewing by the user.

[0039] The screen 30 can be a matte screen (film on glass, FOG) or a liquid crystal display (LCD), and this application does not make any specific limitation in this regard.

[0040] The light-transmitting cover 50 is located on the side of the screen 30 opposite to the backlight assembly 40, and the light-transmitting cover 50 is fixed to the side frame portion 21. For example, the light-transmitting cover 50 can be glued to the side frame portion 21. The light-transmitting cover 50 is used to provide waterproof and dustproof protection for the screen 30 and the backlight assembly 40. The materials of the light-transmitting cover 50 include, but are not limited to, glass and acrylic.

[0041] The middle frame 10 can be a rectangular ring structure. The outer edge of the middle frame 10 is fixed to the end face of the side frame 21 facing the light-transmitting cover 50, and the inner edge is located between the screen 30 and the backlight assembly 40, and is fixedly connected to the screen 30 and the backlight assembly 40.

[0042] Understandable Figure 1 and Figure 2 Some components of the display device 100 are shown schematically; the shape and size of these components are not subject to change. Figure 1 and Figure 2 Due to limitations, the display device 100 may not include at least one of the aforementioned components. For example, the display device 100 may not include the light-transmitting cover 50. Correspondingly, the display device 100 may include other components besides those mentioned above, which will not be elaborated here.

[0043] Figure 1 and Figure 2 In the illustrated embodiment, to adapt to the end face of the side frame 21 facing the light-transmitting cover 50 and the position between the screen 30 and the backlight assembly 40, the middle frame 10 is approximately Z-shaped. This shape of the middle frame 10 ensures that the gap width W1 between the screen 30 and the side frame 21 is at least greater than the sum of the thickness d1 of the middle frame 10, the assembly gap d2 between the vertical portion of the middle frame 10 and the inner side surface of the side frame 21, and the assembly gap d3 between the vertical portion of the middle frame 10 and the screen 30. As a result, the gap between the screen 30 and the side frame 21 is relatively large, requiring a light-shielding layer (e.g., an ink layer) to be provided on the edge of the light-transmitting cover 50 and the area opposite to this gap and the side frame 21. This leads to a larger bezel width and a smaller screen-to-body ratio for the display device 100.

[0044] To resolve the above issues, please refer to Figure 3 , Figure 3 This is a cross-sectional structural diagram of a display device 100 provided in some embodiments of this application. The display device 100 may include a middle frame 10, a back cover 20, a screen 30, a backlight assembly 40, and a light-transmitting cover (not shown in the figure). The structures of the back cover 20, the screen 30, the backlight assembly 40, and the light-transmitting cover can be implemented with reference to the structures shown in any of the above embodiments, and will not be described in detail here.

[0045] The inner side of the side frame 21 is provided with a groove 21a, and the middle frame 10 includes a mounting part 12, which is mounted in the groove 21a.

[0046] In this way, relative to Figure 1 and Figure 2 The solution shown is to fix the outer edge of the middle frame 10 to the end face of the side frame 21 facing the light-transmitting cover 50. The mounting part of the middle frame 10 is installed in the groove 21a on the inner side of the side frame 21. This can prevent the middle frame 10 from affecting the installation space of the screen 30 in the plane where the display surface is located. The size of the screen 30 can be limited only by the side frame 21. Therefore, the size of the screen 30 can be increased, so that the size of the screen 30 is adapted to the size of the space enclosed by the side frame 21. This can reduce the width of the black border on the light-transmitting cover 50, reduce the bezel width, and increase the screen ratio.

[0047] In some embodiments, the gap width between the screen 30 and the side frame 21 can be greater than or equal to 0.1 mm and less than or equal to 0.2 mm. For example, the gap width can be 0.1 mm, 0.12 mm, 0.14 mm, 0.16 mm, 0.18 mm, or 0.2 mm. When the gap width is within this range, the assembly difficulty can be reduced while taking into account the bezel width.

[0048] In some embodiments, please refer to Figure 4 , Figure 4 This is a cross-sectional structural diagram of a display device provided in some embodiments of this application. In this embodiment, the groove 21a penetrates the end face of the side frame portion 21 facing the light-transmitting cover plate 50. This facilitates the installation of the mounting portion within the groove 21a.

[0049] In some embodiments, please refer to Figure 5 , Figure 6 and Figure 7 , Figure 5 for Figure 4 The figure shows a perspective view of the assembly structure of the middle frame 10 and the rear cover 20 of the display device 100. Figure 6 for Figure 5 The image shows a magnified view of the assembly structure in region A. Figure 7 for Figure 5 The diagram shows a partial enlarged view of the assembly structure at region B. The middle frame 10 includes a flat plate portion 11, and a mounting portion 12 is disposed on the outer edge of the flat plate portion 11. The flat plate portion 11 supports the screen 30 and the backlight assembly 40, and the mounting portion 12 is mounted in a recess 21a. The mounting portion 12 can be snapped into the recess 21a, glued to the recess 21a, or fixed to the recess 21a by means of riveting, threaded connection, etc. This application does not specifically limit this.

[0050] Since the mid-frame 10 includes a tablet portion 11, which supports the screen 30 and the backlight assembly 40, the structural complexity of the mid-frame 10 can be reduced. On the other hand, the mid-frame 10 can be further prevented from affecting the installation space of the screen 30, so that the size of the screen 30 is only limited by the side frame portion 21, thereby reducing the bezel width and increasing the screen-to-body ratio.

[0051] In some embodiments, please refer to Figure 4 , Figure 6 and Figure 7 The mounting portion 12 is plate-shaped and is perpendicular to or intersects with the flat plate portion 11. This structure is simple, easy to form, and can be enlarged to allow the mounting portion 12 to be interference-fitted with the groove 21a and snapped into the groove 21a.

[0052] In some embodiments, please refer to the following: Figure 6 and Figure 7 Along the circumference of the side frame portion 21, the two ends of the mounting portion 12 extend beyond the two ends of the flat plate portion 11, and the inner end face of the groove 21a along the circumference of the side frame portion 21 is provided with a limiting groove 21b, and the two ends of the mounting portion 12 are respectively mounted in the limiting groove 21b of the two ends of the groove 21a.

[0053] In this way, the position of the middle frame 10 in the thickness direction of the display device 100 can be restricted by the two sides of the groove 21a along the thickness direction of the display device 100, and the position of the middle frame 10 can be restricted by the two limiting grooves 21b along the direction parallel to the display surface of the display device 100, thereby realizing the positioning of the middle frame 10 on the back cover 20 and ensuring the stability of the connection.

[0054] In some embodiments, the middle frame 10 can be squeezed into the groove 21a through the opening of the groove 21a on the inner side of the side frame portion 21, so that the two ends of the mounting portion 12 respectively enter the two limiting grooves 21b, thereby achieving a snap-fit. This installation method is simple and easy to operate.

[0055] In some embodiments, please refer to Figure 5 The middle frame 10 may include a first middle frame portion 101 and a second middle frame portion 102 arranged circumferentially along the side frame portion 21. The length direction of the first middle frame portion 101 is perpendicular to the length direction of the second middle frame portion 102. In this way, the middle frame 10 extends along an L-shaped path and can be disposed on two adjacent sides of the side frame portion 21, which helps to reduce the number of middle frames 10 and reduce assembly difficulty.

[0056] In some embodiments, please refer to Figure 5The number of mid-frames 10 and recesses 21a are both multiple, and the multiple mid-frames 10 and multiple recesses 21a are arranged circumferentially along the side frame portion 21. Each mid-frame 10 includes a mounting portion, and the mounting portions of the multiple mid-frames 10 are respectively mounted in the multiple recesses 21a. In this way, by using multiple mid-frames 10 to support the screen 30 and the backlight assembly 40, the support stability can be improved. And compared to Figure 2 A single ring-shaped frame can significantly reduce material costs, flatness requirements, and processing difficulty.

[0057] Optionally, the number of middle frames 10 and the number of grooves 21a can be equal, and the mounting portions of multiple middle frames 10 can be installed one-to-one in multiple grooves 21a. This structure is simple and easy to implement. Of course, in other embodiments, the mounting portions of multiple middle frames 10 can also be installed in the same groove 21a, and this application does not specifically limit this.

[0058] Optional, please refer to Figure 5 The side frame portion 21 includes a first side frame portion 211 and a second side frame portion 212 opposite to each other, and a third side frame portion 213 and a fourth side frame portion 214 connected between the first side frame portion 211 and the second side frame portion 212. The plurality of grooves 21a include a first groove 21a1, a second groove 21a2, a third groove 21a3, and a fourth groove 21a4. The first groove 21a1 is provided on the inner surfaces of the first side frame portion 211 and the third side frame portion 213; the second groove 21a2 is provided on the inner surfaces of the third side frame portion 213 and the second side frame portion 212; the third groove 21a3 is provided on the inner surfaces of the second side frame portion 212 and the fourth side frame portion 214; and the fourth groove 21a4 is provided on the inner surfaces of the fourth side frame portion 214 and the first side frame portion 211.

[0059] Based on this, the plurality of middle frames 10 include a first middle frame 10a, a second middle frame 10b, a third middle frame 10c and a fourth middle frame 10d. The mounting part of the first middle frame 10a is mounted in the first groove 21a1, the mounting part of the second middle frame 10b is mounted in the second groove 21a2, the mounting part of the third middle frame 10c is mounted in the third groove 21a3, and the mounting part of the fourth middle frame 10d is mounted in the fourth groove 21a4.

[0060] In this way, the number of middle frames 10 is set to four, which can reduce the number of middle frames 10 while ensuring the stability of the support for the screen 30 and the backlight assembly 40, thereby reducing structural complexity and improving assembly efficiency.

[0061] In some embodiments, please continue reading Figure 4 The display device 100 also includes a screen 30 and a backlight assembly 40, which are located in the area surrounded by the side frame portion 21 and are respectively located on opposite sides of the middle frame 10. This layout is reasonable.

[0062] In some embodiments, the back cover 20 further includes a back plate portion 22 connected to the side frame portion 21, the back plate portion 22 being located on the side of the backlight assembly 40 facing away from the screen 30. In this way, in addition to protecting the periphery of the screen 30 and the backlight assembly 40 by means of the side frame portion 21, the back plate portion 22 can also protect the back side of the screen 30 and the backlight assembly 40, thus ensuring the service life of the display device.

[0063] In some embodiments, the middle frame 10 can be a sheet metal part. Sheet metal parts are easy to process and have high structural strength, which can ensure the structural stability of the display device.

[0064] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0065] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
