[0028] 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.

[0029] 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.

[0030] 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.

[0031] The utility model provides a narrow-frame vehicle-mounted liquid crystal display screen, which comprises a plastic frame, a square backlight module and a square display module, wherein the plastic frame comprises a square bottom plate and four baffles, wherein the four baffles are formed by extending upward from four vertices of the upper surface of the square bottom plate; backlight removal portions are arranged at the four vertices of the square backlight module, and the square backlight module is arranged above the bottom plate and inside the baffles; display removal portions are arranged at the four vertices of the square display module, and the square display module is arranged above the square backlight module and inside the baffles.

[0032] In general, the wiring at the four vertices of a square display module needs to be inwardly oblique, that is, there are some areas near the corners at the four vertices where there are no wiring. In this way, we can cut off the areas without wiring at these four vertices. Since the four vertices on the upper surface of the square base plate extend upward to form four retaining walls, and no retaining walls are set on all sides, it is equivalent to retaining only the retaining walls at the four vertices, and relying on the retaining walls at the four vertices to achieve positioning and fixation, thereby reducing the thickness of the retaining walls on all sides, and achieving a narrow frame without sacrificing the performance of the vehicle structure.

[0033] 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.

[0034] See also Figures 1 to 4 , a narrow-frame vehicle-mounted LCD display provided by the utility model, comprises a plastic frame 1, a square backlight module and a square display module 2, the plastic frame 1 comprises a square bottom plate 11 and four baffles 12, the four baffles 12 are formed by extending upward from four vertices of the upper surface of the square bottom plate 11; backlight removal parts are arranged at the four vertices of the square backlight module, the square backlight module is arranged above the bottom plate 11 and in the baffles 12; display removal parts 200 are arranged at the four vertices of the square display module 2, the square display module 2 is arranged above the square backlight module and in the baffles 12. In general, the wiring at the four vertices of the square display module 2 needs to be an inner oblique line, that is, there are some areas near the corners at the four vertices where there are no wiring. In this way, we can cut off the areas without wiring at the four vertices. Since four retaining walls 12 are extended upward at the four vertices of the upper surface of the square bottom plate 11, and no retaining walls 12 are set on the surrounding areas, it is equivalent to retaining only the retaining walls 12 at the four vertices, relying on the retaining walls 12 at the four vertices to achieve positioning and fixation, thereby reducing the thickness of the retaining walls 12 on the surrounding areas, and achieving a narrow frame without sacrificing the performance of the vehicle-mounted structure.

[0035] Furthermore, chamfers are provided at the vertices of the four retaining walls 12 to avoid damage from sharp corners at the vertices.

[0036] Further, the chamfer is a right angle, and the chamfer is parallel to the edges of the backlight removal portion and the display removal portion 200 .

[0037] In other embodiments, the chamfer may also be a rounded corner to further improve the anti-collision capability.

[0038] See also Figures 1 to 7 As a further optimization scheme of Example 1, in this embodiment, the square display module 2 includes a lower polarizer, a lower substrate 21, an upper substrate 22 and an upper polarizer stacked in sequence from bottom to top, the lower substrate 21 is longer than the upper substrate 22 and extends outward to form a step, the upper surface of the lower substrate 21 located at the step is bound with a driving IC 23 and an FPC 24, and the display removal portion 200 is arranged on the lower polarizer and the lower substrate 21.

[0039] Furthermore, the surface of FPC24 is provided with a traceability label paper 3 and a shielding paper 4, the traceability label paper 3 is pasted on the surface of FPC24, the shielding paper 4 covers the surface of FPC24 and the traceability label paper 3, the shielding paper 4 includes a shielding layer 41, a glue layer 42 and a non-adhesive layer 43 which are stacked in sequence from top to bottom, the size and position of the non-adhesive layer 43 correspond to the size and position of the traceability label paper 3, the non-adhesive layer 43 covers the traceability label paper 3, and the glue layer 42 covers the surface of FPC24. Since the bottom layer of the shielding paper 4 is provided with a non-adhesive layer 43, and the non-adhesive layer 43 covers the traceability label paper 3, and the glue layer 42 covers other areas on the surface of FPC24, that is, by adding a non-adhesive non-adhesive layer 43 in the corresponding area of ​​the traceability label paper 3, the viscosity of the shielding paper 4 is isolated from the traceability label paper 3, which can avoid the problem of easy peeling of the traceability code on the traceability label paper 3 caused by the viscosity of the shielding paper 4 during rework, and improve the traceability of product accessories.

[0040] Furthermore, the thickness of the non-adhesive layer 43 is 0.03mm-0.06mm. The edge of the non-adhesive layer 43 exceeds the edge of the traceability label paper 3 by 1.5mm to 3mm, so as to ensure that the non-adhesive layer 43 can still completely cover the traceability label paper 3 in the case of a deviation in affixing. In addition, the appearance color of the non-adhesive layer 43 and the shielding layer 41 are different, so that the naked eye can easily distinguish whether the non-adhesive layer 43 has a problem of missing affixation, thereby ensuring the consistency of the product.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
