[0024] 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.

[0025] The utility model provides a low-thickness liquid crystal display screen, which comprises a lower frame, a backlight module, a display module, a cover plate and a casing, wherein the lower frame comprises a first bottom plate and a first side wall extending upward from the edge of the first bottom plate; the backlight module is arranged in the lower frame; the display module is arranged above the backlight module; the cover plate is arranged above the display module; the casing comprises a second bottom plate, a second side wall and a bearing portion, the second side wall is formed by extending upward from the edge of the second bottom plate, and the bearing portion is formed by extending inward from the top of the second side wall; the upper surface of the first side wall is glued and fixed to the lower surface of the bearing portion, and the edge of the cover plate is glued and fixed to the upper surface of the bearing portion.

[0026] Since the upper surface of the first side wall is fixed to the lower surface of the bearing portion by pasting, the fixing method of the screw and the client case by using the glue column is eliminated, thereby reducing the thickness of the screw and the glue column. The thickness required for pasting and fixing the first side wall and the bearing portion is very thin, thereby greatly reducing the thickness of the entire LCD screen, making the LCD screen lighter and thinner, and improving the competitiveness of the product.

[0027] 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.

[0028] Example 1

[0029] See also Figure 1 , a low-thickness liquid crystal display screen provided by the utility model comprises a lower frame 1, a backlight module, a display module 2, a cover plate 3 and a casing 4, wherein the lower frame 1 comprises a first bottom plate 11 and a first side wall 12, wherein the first side wall 12 is formed by extending upward from the edge of the first bottom plate 11; the backlight module is arranged inside the lower frame 1; the display module 2 is arranged above the backlight module; the cover plate 3 is arranged above the display module 2; the casing 4 comprises a second bottom plate 41, a second side wall 42 and a bearing portion 43, wherein the second side wall 42 is formed by extending upward from the edge of the second bottom plate 41, and the bearing portion 43 is formed by extending inward from the top of the second side wall 42; the upper surface of the first side wall 12 is glued and fixed to the lower surface of the bearing portion 43, and the edge of the cover plate 3 is glued and fixed to the upper surface of the bearing portion 43. Since the upper surface of the first side wall 12 is fixed to the lower surface of the bearing portion 43 by pasting, the fixing method of the screws and glue columns to the client shell 4 is eliminated, thereby reducing the thickness of the screws and glue columns. The thickness required for pasting and fixing the first side wall 12 and the bearing portion 43 is very thin, thereby greatly reducing the thickness of the entire LCD screen, making the LCD screen lighter and thinner, and improving the competitiveness of the product.

[0030] Example 2

[0031] See also Figure 1 As a further optimization scheme of Example 1, in this embodiment, the display module 2 includes a lower polarizer 21, a lower substrate 22, an upper substrate 23 and an upper polarizer 24 which are sequentially stacked from bottom to top.

[0032] Furthermore, the cover plate 3 and the upper polarizer 24 are fully bonded and fixed by the optical adhesive 5 to avoid bubbles in the bonding of the product and ensure the bonding strength.

[0033] More preferably, the outer periphery of one side of the cover plate 3 exceeds the outer periphery of one side of the lower substrate 22 by 4 mm, so as to reduce the frame width of the cover plate 3 .

[0034] Furthermore, a light-shielding foam 6 is provided on the lower surface of the lower polarizer 21 to block light from passing through the light-shielding foam 6 .

[0035] Furthermore, a driving main board 7 is disposed on the lower surface of the first bottom plate 11 .

[0036] Furthermore, the upper surface of the first side wall 12 and the lower surface of the bearing portion 43, as well as the edge of the cover plate 3 and the upper surface of the bearing portion 43, are both adhered and fixed by means of the structural adhesive 8. When the backlight module is adhered and fixed to the lower surface of the bearing portion 43 by means of the structural adhesive 8, it is necessary to reserve a major gap between the display module 2 and the backlight module to avoid interference due to tolerance.

[0037] Furthermore, the thickness of the structural adhesive 8 is 0.1 mm-0.2 mm, which is very thin, thereby greatly reducing the thickness of the liquid crystal display.

[0038] Furthermore, the lower substrate 22 is longer than the upper substrate 23 and extends outward to form a step.

[0039] Furthermore, the upper surface of the lower substrate 22 located at the step is bound with the driver IC 9 and the FPC.

[0040] 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.

[0041] 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.
