Description

Technical Field

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

[0002] The display device includes a backlight module, a mid-frame, and a liquid crystal display panel. The backlight module includes a backplate, the mid-frame is disposed on the backplate, and a portion of the liquid crystal display panel is embedded within the mid-frame. To avoid interference between the mid-frame and the liquid crystal display panel, the width of the bezel area is increased in conventional display devices to allow for expansion of the materials of the mid-frame and the liquid crystal display panel. However, the increased width of the bezel area leads to an increase in the black border of the display device, making it difficult to meet the requirements for a narrow bezel. Summary of the Invention

[0003] Embodiments of this application provide a display device to improve the problem of wide bezels in conventional display devices.

[0004] Embodiments of this application provide a display device, including: A backlight module, the backlight module including a back plate, the back plate including a bottom plate and a side plate connected to the bottom plate; The middle frame is connected to the side panel; A liquid crystal display panel, wherein the liquid crystal display panel is connected to the middle frame; Wherein, the height of the surface of the middle frame away from the base plate is lower than the height of the surface of the liquid crystal display panel near the base plate, and in a cross-sectional view perpendicular to the thickness direction of the display panel, the distance between the edge of the liquid crystal display panel and the edge of a portion of the side plate located on the same side of the display device near the liquid crystal display panel is no greater than 0.8 mm.

[0005] Furthermore, the middle frame includes a first sub-part, a second sub-part, and a third sub-part. The first sub-part is connected to the third sub-part through the second sub-part. The first sub-part is connected to the side plate, and the third sub-part is connected to the liquid crystal display panel. The distance between the surface of the first sub-part away from the base plate and the surface of the liquid crystal display panel close to the base plate is not less than 0.4 mm.

[0006] Furthermore, the display device also includes a first adhesive member, through which the liquid crystal display panel is connected to the third sub-part. Along the path from the base plate to the liquid crystal display panel, a surface of the first adhesive member away from the base plate is higher than a surface of the first sub-part away from the base plate.

[0007] Furthermore, from a viewing angle along the thickness direction of the display device, the liquid crystal display panel covers the third sub-part, and a portion of the liquid crystal display panel extends beyond the second sub-part near an edge of the liquid crystal display panel.

[0008] Furthermore, the backlight module also includes a light guide plate and an optical film. The light guide plate is disposed on the base plate, and the optical film is disposed on the side of the light guide plate away from the base plate. The distance from the third sub-part to the optical film is not less than 0.5 mm.

[0009] Furthermore, the side plate includes a base and a support portion, the base being connected to the bottom plate and the support portion being connected to the base. Along the path from the bottom plate to the liquid crystal display panel, the surface of the optical film away from the bottom plate is not higher than the surface of the support portion near the bottom plate.

[0010] Furthermore, the support portion, a portion of the base portion, and a portion of the bottom plate form a groove, a portion of the optical film extends into the groove in a direction close to the base portion, and the distance between the edge of the optical film and a surface of the base portion close to the optical film is not less than 1 mm.

[0011] Furthermore, the thickness of the base is not less than 0.8 mm.

[0012] Furthermore, the first sub-part is disposed on the support part; The display device further includes a shim, a second adhesive member, and a cover plate. The shim is disposed on a surface of the first sub-part away from the base plate. The second adhesive member is disposed on a surface of the shim away from the base plate. The cover plate is disposed on a surface of the liquid crystal display panel away from the base plate. A portion of the cover plate is connected to the first sub-part through the second adhesive member.

[0013] Furthermore, along the path from the base plate to the liquid crystal display panel, the surface of the shim away from the base plate is higher than the surface of the liquid crystal display panel near the base plate, and the height of the surface of the shim away from the base plate is lower than the height of the surface of the liquid crystal display panel away from the base plate.

[0014] The beneficial effects of this application are: This application provides a display device in which the height of the surface of the middle frame away from the base plate is lower than the height of the surface of the liquid crystal display panel near the base plate, and the distance between the edge of the liquid crystal display panel and the edge of a part of the side plate located on the same side of the display device near the liquid crystal display panel is no greater than 0.8mm. That is, in the display device of this application, the middle frame is recessed, so that there is a certain distance between the middle frame and the liquid crystal display panel in the thickness direction of the display device. On the one hand, this avoids interference between the material of the liquid crystal display panel and the material of the middle frame due to expansion, which would cause display abnormalities. On the other hand, since only space is needed between the edge of the liquid crystal display panel and the edge of the side plate near the liquid crystal display panel to avoid interference between the liquid crystal display panel and the side plate, no space is needed to reserve for the middle frame, thus reducing the width of the bezel area of ​​the display device and achieving a narrow bezel for the display device.

Detailed Implementation

[0017] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings. The technical solutions described below are for illustrative purposes only and should not be construed as limiting the scope of protection of this application.

[0018] Furthermore, the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are merely used to distinguish different technical features. The terms "multiple" and similar words indicate two or more unless otherwise expressly specified.

[0019] Embodiments of this application provide a display device, with reference to... Figure 1 , Figure 2 , Figure 3 and Figure 4 The display device 10 includes a backlight module 100, a mid-frame 200, and a liquid crystal display panel 300. The backlight module 100 includes a back plate 110, which includes a bottom plate 111 and a side plate 112 connected to the bottom plate 111. The mid-frame 200 is connected to the side plate 112. The liquid crystal display panel 300 is connected to the mid-frame 200. The height of a surface S1 of the mid-frame 200 away from the bottom plate 111 is lower than the height of a surface S2 of the liquid crystal display panel 300 near the bottom plate 111. In a cross-sectional view perpendicular to the thickness direction H of the display panel, the distance a between the edge L2 of the liquid crystal display panel 300 and the edge L3 of a portion of the side plate 112 located on the same side of the display device near the liquid crystal display panel 300 is not greater than 0.8 mm.

[0020] To avoid interference between the display device's frame and the LCD panel, the width of the bezel area is increased in conventional display devices to allow for expansion of the frame and LCD panel materials. However, this increased bezel width leads to a larger black border, making it difficult to meet the requirements for a narrow bezel. Therefore, this application provides a display device in which the height of the surface of the middle frame 200 away from the base plate 111 is lower than the height of the surface of the liquid crystal display panel 300 near the base plate 111, and the distance a between the edge L2 of the liquid crystal display panel 300 and the edge L3 of the side plate 112 located on the same side of the display device near the liquid crystal display panel 300 is not greater than 0.8mm. That is, in the display device of this application, the middle frame 200 is recessed, so that there is a certain distance between the middle frame 200 and the liquid crystal display panel 300 in the thickness direction H of the display device. On the one hand, this avoids interference between the material of the liquid crystal display panel 300 and the material of the middle frame 200 due to expansion, which would cause the display device to fail. On the other hand, since only space is needed between the edge of the liquid crystal display panel 300 and the edge of the side plate 112 near the liquid crystal display panel 300 to avoid interference between the liquid crystal display panel 300 and the side plate 112, there is no need to reserve space for the middle frame 200, thus reducing the width of the bezel area of ​​the display device and achieving a narrow bezel of the display device.

[0021] In this embodiment, reference Figure 1 The display device 10 includes a display area AA and a border area NA surrounding the display area AA. In this embodiment, reference is made to... Figure 4 The distance 'a' between the edge L2 of the liquid crystal display panel 300 and the edge L3 of the side plate 112 near the liquid crystal display panel 300 is not less than 0.4 mm. Preferably, the distance 'a' between the edge L2 of the liquid crystal display panel 300 and the edge L3 of the side plate 112 near the liquid crystal display panel 300 is 0.4 mm, 0.42 mm, 0.44 mm, 0.46 mm, 0.48 mm, 0.50 mm, 0.52 mm, 0.54 mm, 0.56 mm, 0.58 mm, 0.60 mm, 0.62 mm, 0.64 mm, 0.66 mm, 0.68 mm, 0.70 mm, 0.72 mm, 0.74 mm, 0.76 mm, 0.78 mm, or 0.8 mm.

[0022] In this embodiment, reference Figure 3 The liquid crystal display panel 300 includes an array substrate 310 and an array substrate 310 disposed opposite to the array substrate 310.

[0023] In this embodiment, reference Figure 3The liquid crystal display panel 300 further includes a first polarizer 330 and a second polarizer 340. The first polarizer 330 is disposed on a surface of the array substrate 310 near the base plate 111, and the second polarizer 340 is disposed on a surface of the opposing substrate 320 away from the base plate 111.

[0024] In this embodiment, reference Figure 3 , Figure 4 The middle frame 200 includes a first sub-part 210, a second sub-part 220, and a third sub-part 230. The first sub-part 210 is connected to the third sub-part 230 through the second sub-part 220. The first sub-part 210 is connected to the side plate 112, and the third sub-part 230 is connected to the liquid crystal display panel 300. The distance b between the surface S1 of the first sub-part 210 away from the bottom plate 111 and the surface S2 of the liquid crystal display panel 300 close to the bottom plate 111 is not less than 0.4 mm. Preferably, the distance b between the surface of the first sub-part 210 away from the base plate 111 and the surface of the liquid crystal display panel 300 near the base plate 111 is 0.41mm, 0.42mm, 0.43mm, 0.44mm, 0.45mm, 0.46mm, 0.47mm, 0.48mm, 0.49mm, 0.50mm, 0.51mm, 0.52mm, 0.53mm, 0.54mm, 0.55mm, 0.56mm, 0.57mm, 0.58mm, 0.59mm, 0.60mm, 0.61mm, 0.62mm, 0.63mm, 0.64mm, 0.65mm, 0.66mm, 0.67mm, 0.68mm, 0.69mm, or 0.7mm.

[0025] It is understood that in this embodiment, the middle frame 200 includes a first sub-part 210, a second sub-part 220, and a third sub-part 230. The first sub-part 210 is connected to the third sub-part 230 through the second sub-part 220. The first sub-part 210 is connected to the side plate 112, and the third sub-part 230 is connected to the liquid crystal display panel 300. The distance between the surface S1 of the first sub-part 210 away from the base plate 111 and the surface S2 of the liquid crystal display panel 300 near the base plate 111 is not less than 0.4 mm. After the middle frame 200 is recessed, the middle frame 200 and the liquid crystal display panel 300 will not interfere with each other in the horizontal direction. However, there is a risk that they will interfere with each other in the thickness direction H of the display device. Therefore, the distance b between the surface of the first sub-part 210 away from the base plate 111 and the surface of the liquid crystal display panel 300 close to the base plate 111 is set to be not less than 0.4mm. This can reduce the risk of interference between the liquid crystal display panel 300 and the middle frame 200 in the thickness direction H of the display device, thereby further reducing the risk of display abnormalities of the display device.

[0026] It should be noted that the distance b between the surface S1 of the first sub-part 210 away from the base plate 111 and the surface S2 of the liquid crystal display panel 300 near the base plate 111 is the distance from the surface of the first polarizer 330 near the base plate 111 to the surface of the first sub-part 210 away from the base plate 111.

[0027] In this embodiment, reference Figure 3 , Figure 6 The surface S1 of the first sub-part 210 away from the base plate 111 is higher than the surface of the third sub-part 230 away from the base plate 111.

[0028] In this embodiment, reference Figure 3 , Figure 6 The display device further includes a first adhesive member 400, through which the liquid crystal display panel 300 is connected to the third sub-part 230. Along the path from the base plate 111 to the liquid crystal display panel 300, a surface S3 of the first adhesive member 400 away from the base plate 111 is higher than a surface S1 of the first sub-part 210 away from the base plate 111.

[0029] It is understood that in this embodiment, since the display device further includes a first adhesive member 400, the liquid crystal display panel 300 is connected to the third sub-part 230 through the first adhesive member 400. Along the path H from the base plate 111 to the liquid crystal display panel 300, the surface S3 of the first adhesive member 400 away from the base plate 111 is higher than the surface S1 of the first sub-part 210 away from the base plate 111. On the one hand, the first adhesive member can serve as an adhesive to connect the liquid crystal display panel 300 to the middle frame 200; on the other hand, after the middle frame 200 is lowered... The distance between the liquid crystal display panel 300 and the portion of the middle frame 200 located directly below it is increased, thereby setting the surface S3 of the first adhesive member 400 away from the base plate 111 to be higher than the surface S1 of the first sub-part 210 away from the base plate 111. In other words, the first adhesive member has a greater thickness, so that the first adhesive member can play a role in raising it, so as to ensure the height difference between the surface of the liquid crystal display panel 300 away from the base plate 111 and the surface of the side plate 112 away from the base plate 111, and reduce the problem of abnormal appearance of the display device caused by excessive height of the liquid crystal display panel 300 and the side plate 112.

[0030] In this embodiment, reference Figure 3 From a viewing angle along the thickness direction H of the display device, the liquid crystal display panel 300 covers the third sub-part 230, and a portion of the liquid crystal display panel 300 extends beyond the second sub-part 220 near an edge L1 of the liquid crystal display panel 300.

[0031] It is understood that in this embodiment, since the display panel and the middle frame do not interfere with each other in the L direction after the middle frame is lowered, a part of the liquid crystal display panel 300 is set to extend beyond the second sub-part 220 near an edge L1 of the liquid crystal display panel 300, so as to reduce the distance from the edge L2 of the display panel to the edge L3 of the side plate near the side plate 112 near the liquid crystal display panel 300, thereby reducing the width of the bezel of the display device and realizing a narrow bezel of the display device.

[0032] In this embodiment, reference Figure 3 , Figure 4The backlight module 100 further includes a light guide plate 120 and an optical film 130. The light guide plate 120 is disposed on the base plate 111, and the optical film 130 is disposed on the side of the light guide plate 120 away from the base plate 111. The distance c from the third sub-part 230 to the optical film 130 is not less than 0.5 mm. Preferably, the distance c from the third sub-part 230 to the optical film 130 is 0.50 mm, 0.51 mm, 0.52 mm, 0.53 mm, 0.54 mm, 0.55 mm, 0.56 mm, 0.57 mm, 0.58 mm, 0.59 mm, 0.60 mm, 0.61 mm, 0.62 mm, 0.63 mm, 0.64 mm, 0.65 mm, 0.66 mm, 0.67 mm, 0.68 mm, 0.69 mm, or 0.7 mm.

[0033] It is understandable that after the middle frame 200 is lowered, the distance between the third sub-part 230 of the middle frame 200 and the optical film 130 decreases, which may cause interference between the third sub-part 230 of the middle frame 200 and the optical film 130, resulting in display abnormalities in the display device. Therefore, in this embodiment, the backlight module 100 further includes a light guide plate 120 and an optical film 130. The light guide plate 120 is disposed on the base plate 111, and the optical film 130 is disposed on the side of the light guide plate 120 away from the base plate 111. The distance c from the third sub-part 230 to the optical film 130 is not less than 0.5 mm. That is to say, after the middle frame 200 is lowered, sufficient distance is still maintained between the third sub-part 230 of the middle frame 200 and the optical film 130, thereby reducing the risk of interference between the third sub-part 230 of the middle frame 200 and the optical film 130, which could cause display abnormalities in the display device.

[0034] In this embodiment, reference Figure 3 , Figure 4 The side plate includes a base 1121 and a support 1122. The base is connected to the bottom plate 111, and the support 1122 is connected to the base 1121. On the path H along the bottom plate 111 toward the liquid crystal display panel 300, the surface S5 of the optical film 130 away from the bottom plate 111 is not higher than the surface S4 of the support 1122 near the bottom plate 111.

[0035] It is understood that in this embodiment, the side plate includes a base 1121 and a support 1122. The base 1121 is connected to the bottom plate 111, and the support 1122 is connected to the base 1121. On the path H along the bottom plate 111 pointing to the liquid crystal display panel 300, the surface S5 of the optical film 130 away from the bottom plate 111 is not higher than the surface S4 of the support near the bottom plate 111. That is, the groove 113 can provide expansion space for the light guide plate 120 and the optical film 130, thereby reducing the risk of interference between the light guide plate 120, the optical film 130 and the side plate 112 causing display abnormalities in the display device.

[0036] In this embodiment, the thickness of the base 1121 is less than the thickness of the base plate 111.

[0037] It should be noted that in this embodiment, the thickness of the base 1121 is less than the thickness of the bottom plate 111. That is, the support 1122 is formed by removing a portion of the side plate 112, and the groove 113 is formed by removing a portion of the side plate.

[0038] In this embodiment, reference Figure 3 , Figure 4 The support portion 1122, a portion of the base portion 1121, and a portion of the bottom plate 111 form a groove 113. A portion of the optical film 130 extends into the groove in a direction close to the base portion. Along a direction L perpendicular to the thickness direction H of the display device, the distance d between the edge of the optical film 130 and the bottom wall of the groove 113 is not less than 1 mm. Preferably, the distance d is 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, or 3 mm.

[0039] It is understood that in this embodiment, since the support portion 1122, a portion of the base portion 1121, and a portion of the bottom plate 111 form a groove 113, and a portion of the optical film 130 is located within the groove 113, the distance d between the edge of the optical film 130 and the bottom wall of the groove 113 along the thickness direction H perpendicular to the display device is not less than 1 mm, so that there is sufficient distance between the optical film 130 and the side plate 112, preventing interference between the optical film 130 and the side plate 112 due to expansion, thereby effectively reducing the risk of display abnormalities caused by interference between the optical film 130 and the side plate 112.

[0040] It should be noted that in the display device, in order to ensure the light effect emitted by the backlight module 100, a portion of the optical film 130 needs to extend beyond the edge of the light guide plate 120. That is, in the above embodiment, the distance between the edge of the light guide plate 120 and the side plate 112 is greater than the distance between the edge of the optical film 130 and the surface of the side plate 112 near the optical film 130.

[0041] In this embodiment, reference Figure 3 , Figure 4 The thickness e of the base is not less than 0.8 mm. Preferably, the thickness e of the base is 0.81 mm, 0.82 mm, 0.83 mm, 0.84 mm, 0.85 mm, 0.86 mm, 0.87 mm, 0.88 mm, 0.89 mm, 0.90 mm, 0.91 mm, 0.92 mm, 0.93 mm, 0.94 mm, 0.95 mm, 0.96 mm, 0.97 mm, 0.98 mm, 0.99 mm, or 1 mm.

[0042] It is understood that in this embodiment, since the thickness e of the base 1121 is not less than 0.8mm, that is, the thickness e of a portion of the side plate 112 after the groove 113 is provided is not less than 0.8mm, the strength of the side plate 112 can be guaranteed, and the insufficient strength of the side plate 112 can be avoided to prevent the support of the back plate 110 from failing, thereby improving the structural stability of the display device.

[0043] In this embodiment, reference Figure 3 , Figure 4 , Figure 5 The first sub-part is disposed on the support part; the display device further includes a shim 500, a second adhesive 600 and a cover plate 700. The shim 500 is disposed on a surface of the first sub-part 210 away from the base plate 111. The second adhesive 600 is disposed on a surface of the shim 500 away from the base plate 111. The cover plate 700 is disposed on a surface of the liquid crystal display panel 300 away from the base plate 111. A portion of the cover plate 700 is connected to the first sub-part 210 through the second adhesive 600.

[0044] Understandably, after the middle frame 200 is recessed, in order to ensure the connection between the middle frame 200 and the side plate 112, a support part is provided on the surface of the side plate 112 away from the bottom plate 111, so that the first sub-part 210 of the middle frame 200 can be connected to the support part. However, there is a large step difference between the first sub-part 210 and the cover plate 700, which makes it difficult for the middle frame 200 to provide effective support for the cover plate 700, resulting in a reduction in the strength of the edge of the display device. Therefore, in this embodiment, a support portion is provided on the surface of the side plate 112 away from the bottom plate 111. While the first sub-part is provided on the support portion, the display device also includes a shim 500. The shim 500 is provided on the surface of the first sub-part 210 away from the bottom plate 111. The second adhesive 600 is provided on the surface of the shim 500 away from the bottom plate 111. The cover plate 700 is provided on the surface of the liquid crystal display panel 300 away from the bottom plate 111. A portion of the cover plate 700 is connected to the first sub-part 210 through the second adhesive 600. On the one hand, the shim 500 can play a role in raising the height, solving the defect of the step difference between the first sub-part 210 of the middle frame 200 and the cover plate 700, so that the middle frame 200 can effectively support the cover plate 700, thereby improving the strength of the frame area of ​​the display device.

[0045] In this embodiment, the shim 500 includes black light-blocking adhesive.

[0046] In this embodiment, reference Figure 3 Along the path from the base plate 111 to the liquid crystal display panel 300, the surface of the shim 500 away from the base plate 111 is higher than the surface of the liquid crystal display panel 300 near the base plate 111, and the height of the surface of the shim 500 away from the base plate 111 is lower than the height of the surface of the liquid crystal display panel 300 away from the base plate 111.

[0047] The specific embodiments of this application have been described in detail above. The embodiments disclosed above are merely preferred embodiments of this application. Those skilled in the art can make many modifications and improvements without departing from the concept of this application. All such modifications and improvements fall within the scope of protection defined by the claims of this application.
