[0027] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0028] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.
[0029] In addition, the terms "first", "second", and "third" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second", and "third" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.
[0030] The present utility model provides a low-thickness liquid crystal display screen, which includes a lower frame, a backlight module, and a display module. The lower frame includes a bottom plate and side walls extending upward from the edge of the bottom plate. There is a notch on one of the side walls, and at least one positioning post is provided on the outer side of the bottom plate on one side of the notch; the backlight module is disposed on the upper surface of the bottom plate; the display module is disposed above the backlight module. The display module leads out an FPC outward. Components are provided on the front surface of the FPC, and a reinforcing plate is provided on the back surface of the FPC at the position of the components. Positioning holes corresponding to the positions and quantities of the positioning posts are provided on the FPC and the reinforcing plate, and the positioning holes are located on one side of the components.
[0031] Since positioning posts are provided on the outer side of the bottom plate, and corresponding positioning holes are provided on the FPC and the reinforcing plate, when the FPC is bent to the back surface of the lower frame, the area where the components and the reinforcing plate are located can be bent to the outer side of the bottom plate and fixed with the positioning posts through the positioning holes, so that the components are not fixed on the back surface of the lower frame, thereby avoiding the increase in the overall height of the liquid crystal display screen due to the height of the components, and further reducing the thickness of the liquid crystal display screen and improving the competitiveness of the product.
[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings. The present utility model will be described in detail below with reference to the drawings and embodiments. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.
[0033] Please refer to Figures 1 to 4, A low-thickness liquid crystal display screen provided by the present utility model, which includes a lower frame 1, a backlight module, and a display module 2. The lower frame 1 includes a bottom plate 11 and side walls 12 extending upward from the edge of the bottom plate 11. In this embodiment, there are four side walls 12, and a notch 13 is provided on one of the side walls 12. At least one positioning post 14 is provided on the outer side of the bottom plate 11 on one side of the notch 13; the backlight module is arranged on the upper surface of the bottom plate 11; the display module 2 is arranged above the backlight module. An FPC 3 is led out from the display module 2. Components 4 are arranged on the front surface of the FPC 3, and a reinforcing plate 5 is arranged on the back surface of the FPC 3 at the position of the components 4. Positioning holes 31 corresponding to the position and number of the positioning posts 14 are provided on the FPC 3 and the reinforcing plate 5, and the positioning holes 31 are located on one side of the components 4. Since the positioning posts 14 are provided on the outer side of the bottom plate 11, and the corresponding positioning holes 31 are provided on the FPC 3 and the reinforcing plate 5, when the FPC 3 is bent to the back surface of the lower frame 1, the area where the components 4 and the reinforcing plate 5 are located can be bent to the outer side of the bottom plate 11 and fixed with the positioning posts 14 through the positioning holes 31, so that the components 4 are not fixed on the back surface of the lower frame 1, thereby avoiding the increase in the overall height of the liquid crystal display screen due to the height of the components 4, and further reducing the thickness of the liquid crystal display screen and improving the competitiveness of the product.
[0034] Further, in this embodiment, there are two positioning holes 31 which are respectively arranged on both sides of the components 4, so that the FPC 3 and the reinforcing plate 5 can be firmly fixed on the positioning posts 14.
[0035] Further, a rubber plug is arranged on the positioning post 14. After the positioning hole 31 of the FPC 3 is sleeved on the positioning post 14, the rubber plug can be sleeved to prevent the FPC 3 from bouncing out due to stress.
[0036] Further, the sum of the thicknesses of the FPC 3, the components 4, and the reinforcing plate 5 is less than the width of the side wall 12, so that the FPC 3, the components 4, and the reinforcing plate 5 can be hidden in the notch 13 of the side wall 12, without any impact on the overall thickness, and improving the competitiveness of the product.
[0037] Please refer to Figure 5 and Figure 6As a further optimization scheme of Example 1, in this embodiment, an insulating shielding integrated layer 6 is attached to the lower surface of FPC3, and the insulating shielding integrated layer 6 includes insulating paper 61 and conductive shielding material 62. The conductive shielding material 62 is arranged above the insulating paper 61, and the area of the insulating paper 61 is smaller than the area of the conductive shielding material 62. The insulating paper 61 can completely cover the component 4. The conductive shielding material 62 has a through hole 63 at the edge of the insulating paper 61, and the through hole 63 is located in the area where no component is provided. Since the conductive shielding material 62 has a through hole 63 at the edge of the insulating paper 61, the operator can see the edge of the insulating paper 61, so that the operator can judge the position of the insulating paper 61 when attaching, so as to avoid being attached to the component 4 in an offset manner or not being attached, thereby preventing a short circuit and avoiding economic losses.
[0038] Furthermore, the through hole 63 is a circular hole, and one end of the opening waste is connected to the conductive shielding material 62. So that the position of the insulating paper 61 can still be observed by breaking the opening waste at the circular hole, and the opening waste is covered back after being pasted, so as to avoid the opening being unable to ensure conductive shielding.
[0039] Furthermore, a double-sided tape is provided at the bottom of the waste material with holes, and the waste material with holes is pasted back by the double-sided tape to avoid failure to ensure conductive shielding at the holes.
[0040] Furthermore, one side of the insulating paper 61 extends beyond the conductive shielding material 62, so that the operator can judge the specific position of the insulating paper 61 through the insulating paper 61 extending beyond the conductive shielding material 62, thereby avoiding biased or no attachment to the component 4, thereby preventing a short circuit and avoiding economic losses.
[0041] Furthermore, the conductive shielding material 62 is conductive paper or copper foil, which can form a conductive shielding effect.
[0042] 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.
[0043] Obviously, the embodiments described above are only a part of the embodiments of this application, rather than all of them.
