[0006] Furthermore, a second buffer is provided at one end of the display screen away from the first buffer, the second buffer is attached to the lower end surface of the display screen through an adhesive, and the second buffer is located between the display screen and the optical film assembly.

[0007] In the above solution, by providing the second buffer, the buffer effect is enhanced, the influence of external vibration and impact on the display device is reduced, and the display effect is ensured.

[0008] Furthermore, the sum of the thickness of the first buffer component and the adhesive component, and the sum of the thickness of the second buffer component and the adhesive component are both greater than 0.4 mm.

[0009] In the above solution, the first buffer and the second buffer are selected to have a certain thickness so that a sufficient gap is left between the optical film group and the display screen in the vertical direction, further reducing the damage caused by friction between the optical film group and the display screen.

[0010] Furthermore, the first buffer component and the second buffer component are made of foam.

[0011] In the above solution, the use of foam can not only play a buffering role, but also effectively prevent dust and other pollutants from entering the interior of the display device, thereby ensuring the normal operation of the vehicle-mounted display device and extending its service life.

[0012] Furthermore, the backlight module includes a light guide plate, and the light guide plate is arranged in the accommodating groove and on a side of the optical film group close to the back plate.

[0013] In the above solution, by reasonably arranging the positional relationship between the light guide plate and the optical film group, the light can be better regulated and optimized during the propagation process, thereby improving the uniformity and brightness of the backlight effect.

[0014] Furthermore, the backlight module includes a light source, the light source is arranged on the side plate, and the light source and the light guide plate are arranged opposite to each other.

[0015] In the above solution, since the light source and the light guide plate are arranged relative to each other, the light emitted by the light source can be directly and efficiently transmitted to the light guide plate, which reduces the loss of light during the transmission process and improves the utilization rate of light energy.

[0016] Furthermore, the optical film set includes one or more of an anti-peep film, a middle brightness enhancement film, a lower brightness enhancement film and a diffusion film.

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0024] At present, some display devices require narrower and narrower borders, resulting in infinite compression of the design space of the middle frame. The utility model removes the original middle iron frame, and at the same time removes the fixing tape and assembly buckles of the middle iron frame to reduce the deformation of the middle iron frame and the abnormality of the display device caused by foreign matter rubbed between the middle iron frame and the bottom shell or the diaphragm.

[0025] like Figure 1 and Figure 2As shown, in a preferred embodiment, a frameless display device of the utility model includes a display screen 1 and a backlight module 2. The display screen 1 is covered on the backlight module 2, and the backlight module 2 includes a back plate 21, an optical film group 22 and a first buffer 23. The back plate 21 serves as the basic supporting structure of the backlight module. The back plate 21 is composed of a bottom plate 211 and a side plate 212. The bottom plate 211 and the side plate 212 together form a receiving groove. The main function of this receiving groove is to accommodate the optical film group 22. The optical film group 22 may include one or more of an anti-peep film, a middle light-enhancing film, a lower light-enhancing film and a diffusion film. These films modulate and optimize the light to achieve the best display effect. In this embodiment, the optical film group 22 includes an anti-peep film, a middle light-enhancing film, a lower light-enhancing film and a diffusion film stacked in sequence. The anti-peep film can effectively prevent side peeping and protect the user's privacy; the middle light-enhancing film and the lower light-enhancing film can enhance the brightness and uniformity of light; the diffusion film can evenly diffuse the light over the entire display screen and eliminate bright and dark areas.

[0026] like Figure 1 As shown, one end of the first buffer 23 is attached to the upper end surface of the side plate 212 through an adhesive member, and the other end of the first buffer 23 extends between the display screen 1 and the optical film group 22, and is connected to the lower end surface of the display screen 1 through an adhesive member, so that an effective buffer layer is formed between the display screen 1 and the optical film group 22. By setting the first buffer 23 in this position, the force caused by external vibration or impact can be effectively absorbed and buffered, and the optical film group 22 and the display screen 1 can be protected from damage. Among them, the adhesive member can be a double-sided tape to ensure the convenience of installation of the first buffer 23.

[0027] like Figure 2 As shown, in order to further improve the stability of the frameless display device, a second buffer 24 is provided at one end of the display screen 1 away from the first buffer 23. The second buffer 24 is attached to the lower end surface of the display screen 1 through an adhesive member. The second buffer 24 is located between the display screen 1 and the optical film group 22. In this embodiment, the first buffer 23 is provided on the light source side of the frameless display device, and the second buffer 24 is provided on the opposite side or on the left and right sides of the light source of the frameless display device. In some embodiments, the first buffer 23 can be provided on the opposite side or on the left and right sides of the light source, and the second buffer 24 is provided on the light source side. The first buffer 23 and the second buffer 24 work together to achieve a double buffer design, which can further enhance the stability of the frameless display device.

[0028] like Figure 1 and Figure 2As shown, the backlight module 2 also includes a light guide plate 25 and a light source 26. The light guide plate 25 is arranged in the receiving groove and is located on the side of the optical film group 22 close to the back plate 21. The light source 26 is arranged on the side plate 212, opposite to the light guide plate 25, so that the light source can directly irradiate the light guide plate, maximizing the utilization rate of light. The light emitted by the light source 26 is evenly distributed to the entire backlight module 2 through the light guide plate 25, providing uniform and bright light for the display screen 1. Among them, the light source 26 can use an efficient and stable LED lamp or other light-emitting element, which can emit bright light.

[0029] In order to ensure the buffering effect, as a further embodiment of the first buffer 23 and the second buffer 24, the sum of the thickness of the first buffer 23 and the adhesive member, and the sum of the thickness of the second buffer 24 and the adhesive member are both greater than 0.4 mm, so that sufficient gaps are reserved in the vertical direction to prevent the optical film group 22 from contacting and rubbing with the display screen 1 when jumping, thereby avoiding foreign matter or damage to the display screen 1. By designing the buffer and the adhesive member to a certain thickness, the buffering effect can be ensured without being too thick to affect the volume and weight of the entire device.

[0030] In this embodiment, in terms of material selection, foam is used for both the first buffer 23 and the second buffer 24. The foam can not only play a buffering role, but also effectively prevent dust and other pollutants from entering the interior of the display device. Therefore, the frameless display device of the present invention solves the support problem of the dustproof foam and solves the problem of abnormality caused by the upward movement of the optical film group 22 and the friction with the display screen 1 because the foam forms a buffer layer.

[0031] The disclosed embodiment also provides a car, which includes the above-mentioned frameless display device. Traditional in-vehicle display screens are often surrounded by thick frames, which to a certain extent limit the visible area of ​​the screen and affect the viewing experience. In this embodiment, the in-vehicle display device of the car adopts the frameless display device, which eliminates this disadvantage to the greatest extent, not only making the screen more concise and beautiful, providing a good visual experience for the driver, but also because the first buffer member and the second buffer member adopt a special position design and material selection, which can effectively absorb and disperse the impact force from the outside, protect the display screen from damage, and do not affect the dustproof effect of the frameless display device.

[0032] In summary, the frameless display device not only has a beautiful appearance, but also can effectively protect the display screen 1 and the optical film group 22 to ensure stable operation, and does not affect the dustproof effect of the frameless display device. Therefore, the utility model is practical.
