[0023] 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.
[0024] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
[0025] 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.
[0026] The utility model provides a low-thickness vehicle-mounted liquid crystal display screen, which comprises a lower substrate and an upper substrate arranged above the lower substrate, a frame glue is arranged between the lower substrate and the upper substrate, liquid crystal is poured between the lower substrate and the upper substrate within the frame glue, a lower polarizing film is plated on the lower surface of the lower substrate, an upper polarizing film is plated on the upper surface of the upper substrate, a cover plate is arranged above the upper substrate, and the cover plate is fully bonded to the upper substrate by optical glue.
[0027] Since the lower surface of the lower substrate is coated with a lower polarizing film, and the upper surface of the upper substrate is coated with an upper polarizing film, instead of using lower and upper polarizers in traditional solutions, the thickness can be greatly reduced, and the operation of affixing upper and lower polarizers is eliminated, reducing equipment and labor investment, thereby reducing product costs and improving product competitiveness.
[0028] 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 having 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.
[0029] Example 1
[0030] See also Figure 1 , a low-thickness vehicle-mounted liquid crystal display screen provided by the utility model comprises a lower substrate 1 and an upper substrate 2 arranged above the lower substrate 1, a frame glue is arranged between the lower substrate 1 and the upper substrate 2, liquid crystal is poured between the lower substrate 1 and the upper substrate 2 located in the frame glue, a lower polarizing film 3 is plated on the lower surface of the lower substrate 1, an upper polarizing film 4 is plated on the upper surface of the upper substrate 2, a cover plate 5 is arranged above the upper substrate 2, and the cover plate 5 is fully bonded to the upper substrate 2 by optical glue. Since the lower surface of the lower substrate 1 is plated with the lower polarizing film 3 and the upper surface of the upper substrate 2 is plated with the upper polarizing film 4, instead of using the lower polarizer and the upper polarizer in the traditional solution, its thickness can be greatly reduced, and the operation of pasting the upper and lower polarizers is also cancelled, reducing equipment investment and labor investment, thereby reducing product costs and improving product competitiveness.
[0031] Furthermore, the thickness of the lower polarizing film 3 and the upper polarizing film 4 is 1 μm-5 μm, which is much thinner than the thickness of the conventional lower polarizing film and the upper polarizing film, thereby reducing the thickness of the liquid crystal display screen.
[0032] Example 2
[0033] See also Figure 2 As a further optimization scheme of Example 1, in this embodiment, an anti-fall plate 6 is provided above the cover plate 5, and an ink layer 61 is provided on the lower surface of the anti-fall plate 6 located in the non-visible area. The cover plate 5 and the anti-fall plate 6 are fixed by an adhesive layer 62, and the adhesive layer 62 completely covers the ink layer 61 and the lower surface of the anti-fall plate 6. Since there is another layer of anti-fall plate 6 above the cover plate 5, and the adhesive layer 62 is printed on the entire surface of the back of the anti-fall plate 6, it covers the ink layer 61 in the non-visible area and the lower surface of the anti-fall plate 6 in the visible area, fills the ink step difference, and does not cause the phenomenon of laminating bubbles and edge yellow spots. The cover plate 5 can be fully laminated with the upper polarizer through liquid optical glue. Since the cover plate 5 is not provided with an ink layer 61, it will not cause the phenomenon of laminating bubbles and edge yellow spots, thereby avoiding display abnormalities of the liquid crystal display module, thereby reducing the probability of defective products in the liquid crystal display module, and the production and manufacturing costs of the liquid crystal display module will also be greatly reduced.
[0034] And when the anti-fall plate 6 is impacted by external force, the anti-fall plate 6 will break first. Due to the buffering effect of the adhesive layer 62, the cover plate 5 is not easy to break, so the cover plate 5 and the main screen can be well protected. When the anti-fall plate 6 is broken, the anti-fall plate 6 can be easily peeled off, and only a new anti-fall plate 6 needs to be replaced. There is no need to replace the entire LCD display module, thereby greatly reducing the maintenance cost of the LCD display module, thereby improving the product competitiveness of the LCD display module, thereby meeting the company's growing quality requirements.
[0035] Further, the thickness of the ink layer 61 is 8 μm to 15 μm.
[0036] Furthermore, the thickness of the adhesive layer 62 is 50 μm.
[0037] Furthermore, the thickness of the anti-fall plate 6 is 5 mm to 10 mm, and the thickness of the cover plate 5 is 3 mm to 5 mm.
[0038] Furthermore, the upper surface of the anti-fall plate 6 is covered with an anti-fingerprint film layer to prevent user fingerprints from remaining on the anti-fall plate 6 and enhance the aesthetics.
[0039] Furthermore, a color conversion layer is provided on the upper surface of the anti-fingerprint film layer located in the non-display area to further enhance the aesthetics of the product.
[0040] Furthermore, the hardness of the anti-fall plate 6 is greater than the hardness of the cover plate 5 to enhance the protection effect.
[0041] 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.
[0042] Obviously, the embodiments described above are only some embodiments of the present application, rather than all embodiments. The preferred embodiments of the present application are given in the accompanying drawings, but they do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present application more thorough and comprehensive.
