Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to a narrow bezel display screen. Background Technology

[0002] As users' demands for the overall appearance of large-screen display products on the market increase, they require products to be thinner and lighter, that is, thinner and narrower bezels. This places stricter requirements on the product structure. As a result, a product with a significantly reduced overall thickness and bezel size has emerged.

[0003] Due to limitations in the assembly structure, current displays on the market require screws to pass through the back panel and middle frame from back to front to the front of the outer frame when fixing the outer frame to the middle frame. Space needs to be left at the front of the outer frame for the screws, resulting in a wider outer frame, a smaller screen-to-body ratio, and a thicker overall device, which affects the user experience. Utility Model Content

[0004] This utility model provides a narrow bezel display screen, which solves the problems of small screen ratio and large overall thickness of existing narrow bezel display screens.

[0005] This utility model embodiment provides a narrow bezel display screen, which includes: a display panel; a bezel assembly including an outer bezel, a middle frame, and a back panel. The outer bezel has a front frame plate, a side frame plate, and a rear frame plate arranged front and rear. The middle frame is attached and fixed to the side frame plate by a first fastener, and the back panel is attached and fixed to the rear frame plate by a second fastener. The front end of the middle frame is provided with a support portion extending away from the side frame plate. The front and rear sides of the support portion are respectively spaced from the front frame plate and the rear frame plate. The display panel is disposed between the support portion and the front frame plate. The support portion and the back panel are spaced apart to define an clearance space. The first fastener and the second fastener are both located within the clearance space.

[0006] Furthermore, the back panel has a side section extending toward the front frame panel, the side section being attached to the side of the middle frame facing away from the side frame panel, and the side section being fixed to the middle frame by the first fastener.

[0007] Furthermore, the first fastener is a first bolt, which passes vertically through the side frame plate, the middle frame, and the side segment in sequence and extends into the clearance space to fix the middle frame, the side segment, and the side frame plate together.

[0008] Furthermore, the second fastener is a second bolt, which passes vertically through the rear frame plate and the back plate in sequence and extends into the clearance space to fix the back plate and the rear frame plate together.

[0009] Furthermore, it also includes a backlight module, which includes LED beads and a reflective film. The end of the support portion away from the side frame plate is connected to an inclined section that extends obliquely toward the back plate. The LED beads are disposed on the back plate and adjacent to the inclined section. Part of the reflective film is horizontally arranged on the back plate, and another part is obliquely arranged on the inclined section.

[0010] Furthermore, the display panel includes liquid crystal glass and an optical film, and the support portion includes a first stage and a second stage connected in sequence. The distance from the first stage to the front frame is less than the distance from the second stage to the front frame. The liquid crystal glass is disposed on the first stage, and the optical film is disposed on the second stage and spaced apart from the liquid crystal glass.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] The directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "inner," "outer," and "side," are merely for reference to the accompanying drawings. Therefore, the directional terms used are for explanation and understanding of this invention, and not for limiting it. Furthermore, in the accompanying drawings, structures that are similar or identical are indicated by the same reference numerals.

[0021] First refer to Figure 2 , Figure 2 The image shows a solution for a traditional display screen, such as... Figure 2 As shown, the middle frame 2 of the traditional display is fixed by screws 18A. Screws 18A occupy a large amount of space near the front of the bezel 1, and screws 18A cannot be removed. The width Z1 of the traditional bezel 1 is limited by screws 18A and cannot be reduced. The width Z1 of the bezel 1 is relatively wide, which reduces the screen ratio of the whole machine and affects the user experience.

[0022] To address the shortcomings of traditional displays, this invention provides a narrow bezel display screen. The structure of this narrow bezel display screen will be described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 As shown, the narrow bezel display screen includes a display panel 20 and a bezel assembly 10. The display panel 20 may be composed of liquid crystal glass 21, optical film 22, etc. The bezel assembly 10 includes an outer bezel 11, a middle frame 12, and a back plate 13. The outer bezel 11 has a U-shaped cross-section and includes a front frame plate 101, a side frame plate 102, and a rear frame plate 103 arranged front to back. Specifically, the front frame plate 101 and the rear frame plate 103 are opposite and parallel, and the side frame plate 102 is the part connecting the front frame plate 101 and the rear frame plate 103. The middle frame 12 is fixed to the side frame plate 102 by a first fastener 40, and the back plate 13 is fixed to the rear frame plate 103 by a second fastener 50. The first fastener 40 and the second fastener 50 may be bolted.

[0024] The front end of the middle frame 12 is provided with a support portion 121 extending away from the side frame plate 102. The support portion 121 is mainly used to support the display panel 20. The front and rear sides of the support portion 121 are respectively spaced from the front frame plate 101 and the rear frame plate 103. The space between the front side of the support portion 121 and the front frame plate 101 is relatively narrow, which is just enough to accommodate the display panel 20. The display panel 20 is located between the support portion 121 and the front frame plate 101. After the back panel 13 and the rear frame 103 are installed, the support 121 and the back panel 13 are spaced apart to define a clearance space 200. The clearance space 200 is the space between the rear side of the support 121 and the front side of the back panel 13. The space is relatively wide and serves as a space to accommodate the first fixing member 40 and the second fixing member 50. Both the first fixing member 40 and the second fixing member 50 are located within the clearance space 200. Specifically, a small portion of the first fixing member 40 connects the middle frame 12 and the outer frame 11, while the excess portion is located within the clearance space 200. Similarly, a small portion of the second fixing member 50 connects the back panel 13 and the outer frame 11, while the excess portion is located within the clearance space 200. The clearance space 200 provides clearance for the first fixing member 40 and the second fixing member 50. The first fixing member 40 and the second fixing member 50 only occupy the clearance space 200, avoiding the display panel 20 and not occupying the space near the front end of the outer frame 11. Therefore, the width Z2 of the front frame 101 of the outer frame 11 is relatively large compared to... Figure 2 The traditional solution shown has a narrower bezel (Z1), which increases the screen-to-body ratio and provides a better user experience.

[0025] In one embodiment, the back plate 13 has a side segment extending toward the front frame plate 101, making the cross-sectional shape of the back plate 13 L-shaped. The side segment is attached to the side of the middle frame 12 facing away from the side frame plate 102. The middle frame 12 is sandwiched between the side frame plate 102 and the side segment. The side segment is fixed to the middle frame 12 by the first fastener 40. Overall, the middle frame 12 and the side segment are fixed to the side frame plate 102 of the outer frame 11 by the first fastener 40. The connection between the outer frame 11, the middle frame 12 and the back plate 13 is more stable, and the structural stability of the display screen is better.

[0026] Furthermore, such as Figure 1 As shown, the first fixing member 40 adopts a bolt structure. The first fixing member 40 is the first bolt, which is installed by side mounting. Through the corresponding holes on the side frame plate 102 and the middle frame 12, the first bolt passes vertically through the side frame plate 102, the middle frame 12, and the side segment 131 and extends into the clearance space 200 to fix the middle frame 12, the side segment 131 and the side frame plate 102 together. Thus, the excess part of the first bolt is in the clearance space 200, avoiding the display panel 20, reducing the space occupied by the front inner side of the outer frame 11, and improving the screen ratio of the display screen.

[0027] Furthermore, such as Figure 1 As shown, the second fixing member 50 adopts a bolt structure. The second fixing member 50 is a second bolt. The second bolt is installed by the back mounting method. The second bolt passes vertically through the rear frame plate 103 and the back plate 13 in sequence and extends into the clearance space 200 to fix the back plate 13 and the rear frame plate 103 together. Thus, the excess part of the second bolt is in the clearance space 200, avoiding the display panel 20, reducing the space occupied by the front inner side of the outer frame 11, and improving the screen ratio of the display screen.

[0028] In one embodiment, such as Figure 1 As shown, the narrow bezel display also includes a backlight module 30, which includes LED beads 31 and a reflective film 32. The LED beads 31 serve as the backlight source, and the reflective film 32 reflects the light emitted by the LED beads 31 onto the display panel 20. The support portion 121, away from the side frame plate 102, is connected to an inclined section 122 extending towards the back plate 13. The end of the inclined section 122 can extend to contact the side plate. The LED beads 31 are disposed on the back plate 13 and adjacent to the inclined section 122. A portion of the reflective film 32 is horizontally arranged on the back plate 13, and another portion is inclinedly arranged on the inclined section 122. The portion of the reflective film 32 disposed on the back plate 13 and the portion disposed on the inclined section 122 work together to concentrate the light source, making the light source more concentrated and uniformly reflected onto the display panel 20, thus improving the display effect.

[0029] In one embodiment, such as Figure 1As shown, the display panel 20 includes a liquid crystal glass 21 and an optical film 22. The optical film 22 may specifically include a polarizer 22A and a diffusion film 22B. The support portion 121 includes a first stage 1211 and a second stage 1212 connected in sequence. The distance from the first stage 1211 to the front frame plate 101 is less than the distance from the second stage 1212 to the front frame plate 101. The first stage 1211 and the second stage 1212 together form a stepped structure with one high and one low. The liquid crystal glass 21 is disposed on the first stage 1211, and the optical film 22 is disposed on the second stage 1212 and spaced apart from the liquid crystal glass 21. The liquid crystal glass 21 is in front, and the optical film 22 is behind.

[0030] Furthermore, such as Figure 1 As shown, the distance between the liquid crystal glass 21 and the optical film 22 is d, where 0.5mm≤d≤1mm. In practical applications, the design of the distance between the liquid crystal glass 21 and the optical film 22 is very important because both the optical film 22 and the liquid crystal glass 21 are made of relatively soft materials. During the transportation of the display screen, the liquid crystal glass 21 and the optical film 22 will undergo up-and-down arc deformation, causing them to come into contact and rub against each other, which can easily lead to scratches on the surface of the liquid crystal glass 21, resulting in abnormal display images. Therefore, a reasonable value needs to be selected. Figure 2 The conventional display shown has a relatively large spacing d0 between the liquid crystal glass 14 and the optical films 15A and 15B, resulting in a relatively thick overall thickness W2. Therefore, in this embodiment, the spacing d between the liquid crystal glass 21 and the optical film 22 is designed within a reasonable range of 0.5mm to 1mm. This restricts the relative movement space between the optical film 22 and the liquid crystal glass 21, greatly alleviating wear and tear on the liquid crystal glass 21. Simultaneously, with this spacing d, the width between the front frame 101 and the rear frame 103 of the outer frame 11 is significantly reduced, resulting in a significantly reduced overall thickness W2, which improves the user experience.

[0031] Preferably, the distance d between the liquid crystal glass 21 and the optical film 22 is designed to be d=1mm. This value can ensure a reasonable fit between the liquid crystal glass 21 and the optical film 22, alleviate the wear of the liquid crystal glass 21, and make the overall thickness of the display screen relatively small.

[0032] In one embodiment, such as Figure 1 As shown, the first stage 1211 is provided with a first buffer pad 60. The first buffer pad 60 can be made of adhesive. The liquid crystal glass 21 is placed on the first buffer pad 60 and is in close contact with the first buffer pad 60. The first buffer pad 60 can provide a buffering effect for the liquid crystal glass 21 and protect the safety of the liquid crystal glass 21. The distance between the liquid crystal glass 21 and the optical film 22 can also be adjusted by adjusting the thickness of the first buffer pad 60.

[0033] In one embodiment, such as Figure 1 As shown, a second buffer pad 70 is provided on the second stage 1212. The second buffer pad 70 can be adhesive-backed. The optical film 22 is disposed on the second buffer pad 70 and is in close contact with the second buffer pad 70. The second buffer pad 70 can provide a buffering effect for the liquid crystal glass 21 and protect the safety of the liquid crystal glass 21. In addition, the distance between the liquid crystal glass 21 and the optical film 22 can be adjusted by adjusting the thickness of the second buffer pad 70.

[0034] In one embodiment, such as Figure 1 As shown, a third buffer pad 80 is provided on the front frame plate 101. The third buffer pad 80 can be made of adhesive. The front end of the liquid crystal glass 21 is attached to the third buffer pad 80, which can prevent the liquid crystal glass 21 from directly contacting the outer frame 11 and the front frame plate 101, thus protecting the safety of the liquid crystal glass 21.

[0035] In summary, the narrow bezel display of this application optimizes and adjusts the structure of the middle frame and the back panel. The first and second fixing members, which are used to fix the middle frame and the back panel respectively, are set in the clearance space formed between the support part of the middle frame and the rear frame plate of the outer frame, thereby creating clearance and avoiding the display panel. This reduces the space occupied on the inner side of the front of the outer frame, thereby reducing the width of the outer frame and increasing the screen ratio. Furthermore, by reasonably shortening the distance between the liquid crystal glass and the optical film in the display panel, the thickness of the whole device is reduced, thus effectively improving the user experience.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
