[0023] As shown in Figure 1 The present application embodiment discloses a kind of vehicle-mounted display screen, including glass cover plate 1, appearance back shell 2, backlight plate 3 and liquid crystal panel 4;The cavity is equipped in the appearance back shell 2, the appearance back shell 2 is also equipped with the opening being communicated with the cavity, the backlight plate 3 and the liquid crystal panel 4 are set in the cavity by the opening, the backlight plate 3 is glued with the inner wall of the appearance back shell 2, the glass cover plate 1 is set at the opening, to close the opening, one side of the liquid crystal panel 4 is glued with the inner wall of the glass cover plate 1, the backlight plate 3 is located in the side of the liquid crystal panel 4 away from the glass cover plate 1.

[0024] Specifically, the appearance rear shell 2 serves as the appearance modeling of the vehicle-mounted display screen on one hand, and protects the components and elements inside on the other hand. The glass cover plate 1 is the protective glass on the outermost layer of the vehicle-mounted display screen, which is used to protect the precision electronic components such as the display panel from the impact, scratching and abrasion of the external environment. It can effectively prevent the screen from being damaged due to collision or friction, thereby prolonging the service life of the vehicle-mounted display screen. The liquid crystal panel 4 can serve as the display panel. The backlight plate 3 plays a crucial role in the vehicle-mounted display screen. First, the backlight plate 3 is mainly used to provide uniform and sufficient light source for the liquid crystal panel 4, so that the liquid crystal panel 4 can normally display images.

[0025] The vehicle-mounted display screen of the embodiment of the utility model cancels the iron frame structure in the prior art, so that the backlight plate 3 is directly glued with the appearance rear shell 2, thereby the space occupied by the iron frame structure in the appearance rear shell 2 can be saved, and the thickness of the appearance rear shell 2 is further reduced, and the weight of the iron frame structure is reduced, and the vehicle-mounted display screen is more light and thin, and more in line with the current aesthetic needs.

[0026] Further, since the iron frame structure in the prior art is cancelled, the vehicle-mounted display screen of the embodiment of the utility model also has the effect of saving production cost, and about 15 to 30 yuan can be saved according to different sizes.

[0027] In some embodiments, the vehicle-mounted display screen further comprises a diffuser film 5, which is arranged in the cavity, and the diffuser film 5 is arranged between the backlight plate 3 and the liquid crystal panel 4.

[0028] Specifically, the diffuser film 5 is used to optimize the distribution of light and improve the display effect. The diffuser film 5 can efficiently guide the incident light to the required direction, thereby realizing more uniform and brighter picture display.

[0029] In some embodiments, the vehicle-mounted display screen further comprises a reflective film 6, which is arranged in the cavity, the reflective film 6 is arranged between the backlight plate 3 and the appearance rear shell 2, and the reflective film 6 is arranged on the side of the backlight plate 3 away from the liquid crystal panel 4.

[0030] Specifically, the reflective film 6 is used to reduce the reflectivity and reduce the reflection, thereby improving the visibility and safety of the vehicle-mounted display screen.

[0033] In some embodiments, the liquid crystal panel 4 and the inner side wall of the glass cover plate 1 are provided with OCA adhesive 8 to bond the liquid crystal panel 4 and the glass cover plate 1.

[0034] Specifically, the OCA (Optically Clear Adhesive) adhesive is a silicone adhesive. It can greatly reduce light reflection and light loss, thereby improving the brightness and display effect of the vehicle display screen. The OCA adhesive 8 is uniformly arranged along the panel surface of the liquid crystal panel 4 to ensure the adhesion of the glass cover plate 1.

[0035] In some embodiments, the appearance back shell 2 comprises a magnesium alloy shell.

[0036] Further, the appearance back shell 2 can be a magnesium alloy shell, which has the characteristics of light weight and high strength. It can ensure that the vehicle display screen still meets the structural strength requirements after canceling the iron frame structure, and its quality is light, which does not increase the quality of the vehicle display screen compared with the traditional plastic shell, so as to meet the light and thin demand.

[0037] In some embodiments, the thickness of the appearance back shell 2 is 9mm.

[0038] Specifically, the thickness of the appearance back shell 2 is the size corresponding to H in the formula Figure 1 , i.e. the thickness of the vehicle display screen. Since the iron frame structure is canceled, compared with the traditional vehicle display screen whose minimum thickness can only be 12.5mm, the vehicle display screen provided in the embodiment can be 9mm, so that the vehicle display screen is more light and thin.

[0039] In some embodiments, the appearance back shell 2 comprises an integrally formed bottom shell and a side shell; the backlight plate 3 is arranged parallel to the inner wall surface of the bottom shell, and the backlight plate 3 is arranged perpendicular to the inner wall surface of the side shell.

[0040] The utility model embodiment further discloses a multimedia device, comprising the vehicle display screen of the above embodiment, and the multimedia device further comprises a host connected with the vehicle display screen.

[0041] Specifically, the multimedia device is suitable for a vehicle multimedia system, and the multimedia device can comprise a vehicle display screen and a host connected with the vehicle display screen. The vehicle display screen is used for displaying video pictures, pictures, texts and the like of multimedia files, the host is used for controlling the vehicle display screen, and the vehicle display screen can also display a UI interface of a vehicle central control system.

[0042] The utility model embodiment further discloses an automobile comprising the multimedia device of the above embodiment, wherein the multimedia device is arranged in the cabin of the automobile.

[0043] The utility model discloses a kind of vehicle-mounted display, display equipment and multimedia equipment, wherein, vehicle-mounted display screen includes glass cover plate 1, appearance back shell 2, backlight plate 3 and liquid crystal panel 4;Appearance back shell 2 is equipped with cavity in it, appearance back shell 2 is further equipped with the opening being communicated with the cavity, the backlight plate 3 and the liquid crystal panel 4 are set in the cavity by the opening, the backlight plate 3 is glued with the inner wall of appearance back shell 2, the glass cover plate 1 is set at the opening, to close the opening, one side of the liquid crystal panel 4 is glued with the inner wall of glass cover plate 1, the backlight plate 3 is located in the side of liquid crystal panel 4 away from glass cover plate 1.Cancelling the iron frame structural member in traditional technology, the backlight plate 3 is directly glued with appearance back shell 2, so that the space occupied by the iron frame structural member in appearance back shell 2 can be saved, to further reduce the thickness of appearance back shell 2, and the weight of iron frame structural member is reduced, and thus vehicle-mounted display screen is more light and thin, more fit current aesthetic demand.

[0044] The above is merely a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, which should be covered by the protection scope of the present application.
