[0025] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0027] In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0028] The utility model provides an integrated black vehicle-mounted display screen, which comprises a lower polarizer, an array substrate, a color film substrate, an upper polarizer and a cover plate which are sequentially stacked from bottom to top, the cover plate comprising a visible area and a non-visual area, the lower surface of the cover plate located in the non-visual area is provided with a black ink layer, the lower surface of the cover plate located in the visible area is provided with an optical film, the color of the optical film is gray, the array substrate is longer than the color film substrate and extends outward to form a step, and the upper surface of the array substrate located at the step is bound with a driver IC and an FPC.

[0029] Since the color of the optical film in the visible area is gray, it can further increase the grayscale of the visible area, thereby reducing the color difference between the visible area and the non-visible area, improving the integrated black effect, and further improving the product competitiveness of the vehicle display, thereby meeting the growing quality requirements of manufacturers.

[0030] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.

[0031] Example 1

[0032] See also Figure 1 , is an integrated black vehicle-mounted display screen provided by the utility model, which includes a lower polarizer 1, an array substrate 2, a color film substrate 3, an upper polarizer 4 and a cover plate 5 which are sequentially stacked from bottom to top, the cover plate 5 including a visible area and a non-visible area, a black ink layer 51 is arranged on the lower surface of the cover plate 5 located in the non-visible area, an optical film 52 is arranged on the lower surface of the cover plate 5 located in the visible area, the color of the optical film 52 is gray, the array substrate 2 is longer than the color film substrate 3 and extends outward to form a step, and a driver IC and FPC 6 are bound to the upper surface of the array substrate 2 located at the step. Since the color of the optical film 52 located in the visible area is gray, it can further improve the grayscale of the visible area, thereby reducing the color difference between the visible area and the non-visible area, improving the integrated black effect, and further improving the product competitiveness of the vehicle-mounted display screen, thereby meeting the growing quality requirements of production enterprises.

[0033] Furthermore, the material of the optical film 52 is a carbon powder optical film, which is synthesized by mixing a pressure-sensitive adhesive and carbon powder, and the color of the pressure-sensitive adhesive can be adjusted by adding carbon powder to the original liquid of the pressure-sensitive adhesive, and then coated on the optical film 52 substrate to make a gray optical film 52. The transmittance of the water-based adhesive can be controlled according to the amount added. When we need an integrated black effect, we can adjust the appropriate transmittance according to the color of the ink to achieve an integrated black effect.

[0034] Example 2

[0035] See also Figure 2As a further optimization scheme of Example 1, in this embodiment, a two-dimensional code laser area is further provided on the upper surface of FPC6. A black ink layer 61 and a white ink layer 62 provided on the black ink layer 61 are provided on the upper surface of FPC6 located on the two-dimensional code laser area. The white ink layer 62 is formed with a two-dimensional code by laser. Since two layers of ink are provided, the black ink layer 61 and the white ink layer 62, the surface white ink layer 62 is lasered off by laser to expose the bottom black ink layer 61. The area where the laser is lasered is displayed as black. The two-dimensional code generated in this way has a good contrast effect and is easy to scan. At the same time, the two-dimensional code will not fall off and be damaged, which prevents the two-dimensional code from being invalid, and greatly reduces the labor cost.

[0036] Furthermore, the thickness of the black ink layer 61 is 30 μm. ～ 40 μm. The thickness of the white ink layer 62 is 10 μm ～ 20μm. This thickness is the thickness that the commonly used ultraviolet laser can just penetrate, and there is no dust around after the laser irradiation, which has the advantages of high rhythm and efficiency. The reason why the thickness of the lower black ink layer 61 is thicker than the thickness of the upper white ink layer 62 is to avoid laser power energy fluctuations and prevent the black ink layer 61 from being penetrated by the laser and causing damage to the internal layer of FPC6.

[0037] Example 3

[0038] See also Figure 3 As a further optimization scheme of Example 1, in this embodiment, a protrusion 21 is provided on the edge of the upper surface of the array substrate 2 extending outward, and a buffer glue 22 is provided on the upper surface of the array substrate 2 between the protrusion 21 and the color film substrate 3, and the buffer glue 22 abuts against the cover plate 5. Since the edge of the array substrate 2 is provided with a protrusion 21, the protrusion 21 can limit the flow of the buffer glue 22, so that the shape of the buffer glue 22 is easy to control, and there will be no overflow of glue or incomplete glue dispensing. This prevents the liquid crystal display screen from being unable to be assembled with the casing. In addition, the problem of poor buffering effect caused by incomplete glue dispensing and easy rupture of the array substrate 2 is avoided, and the abnormal display of the liquid crystal display screen is prevented.

[0039] Furthermore, the upper surface of the protrusion 21 is flush with the upper surface of the color filter substrate 3 to further limit the flow of the buffer glue 22, so that the shape of the buffer glue 22 is easy to control without overflowing glue or incomplete glue dispensing.

[0040] Furthermore, the buffer glue 22 is silicone glue.

[0041] Furthermore, a chamfer is provided between the protrusion 21 and the array substrate 2 so that the buffer glue 22 can more easily fill the space between the protrusion 21 on the upper surface of the array substrate 2 and the color filter substrate 3. The protrusion 21 with a chamfer can make the buffer glue 22 flow more smoothly into the space between the protrusion 21 on the upper surface of the array substrate 2 and the color filter substrate 3, so that bubbles are less likely to appear.

[0042] Furthermore, the upper surface of the array substrate 2 and the side surfaces of the protrusions 21 are rough surfaces to improve the fixing effect of the buffer glue 22 .

[0043] Furthermore, the rough surface is a frosted surface or a diamond knurled surface to further improve the fixing effect of the buffer glue 22 .

[0044] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
