[0029] In addition, the terms "first", "second", "third" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first", "second", "third" may explicitly or implicitly include at least one of such features. In the description of the present utility model, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.
[0030] The utility model provides a narrow-border liquid crystal display screen, which comprises a lower frame, a backlight module and a display module. The lower frame comprises a square bottom plate and four side walls extending upward from the four edges of the square bottom plate. An avoidance notch is arranged at the connection between two adjacent side walls. The avoidance notch penetrates from the outer surface of the side wall to the inner surface of the side wall. The included angle between the avoidance notch and the adjacent side wall is 43°-48°, and the width of the avoidance notch is at least 1 mm. The backlight module is arranged above the square bottom plate. The display module is arranged above the backlight module.
[0031] Since an avoidance notch is arranged at the connection between two adjacent side walls, the avoidance notch penetrates from the outer surface of the side wall to the inner surface of the side wall, the included angle between the avoidance notch and the adjacent side wall is 43°-48°, the processing difficulty of the avoidance notch is very low, and it can ensure that the four sharp corners of the display module do not collide with the lower frame, thereby reducing the production cost and improving the competitiveness of the product.
[0032] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the drawings. The present invention 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 denote 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 invention and should not be construed as limiting the present invention.
[0033] Please refer to Figure 1 , which is a narrow-border liquid crystal display screen provided by the present invention. It comprises a lower frame 1, a backlight module and a display module 2. The lower frame 1 comprises a square bottom plate 11 and four side walls 12. The four side walls 12 are formed by extending upward from the four edges of the square bottom plate 11. An avoidance notch 13 is arranged at the connection between two adjacent side walls 12. The avoidance notch 13 penetrates from the outer surface of the side wall 12 to the inner surface of the side wall 12. The included angle between the avoidance notch 13 and the adjacent side wall 12 is 43°-48°, and the width of the avoidance notch 13 is at least 1 mm. In this embodiment, the included angle between the avoidance notch 13 and the adjacent side wall 12 is 45°, and the width of the avoidance notch 13 is 5 mm. The backlight module is arranged above the square bottom plate 11. The display module 2 is arranged above the backlight module. Since an avoidance notch 13 is arranged at the connection between two adjacent side walls 12, the avoidance notch 13 penetrates from the outer surface of the side wall 12 to the inner surface of the side wall 12, the included angle between the avoidance notch 13 and the adjacent side wall 12 is 43°-48°, the processing difficulty of the avoidance notch 13 is very low, and it can ensure that the four sharp corners of the display module 2 do not collide with the lower frame 1, thereby reducing the production cost and improving the competitiveness of the product.
[0034] Further, the display module 2 includes a lower polarizer 21, a lower substrate 22, an upper substrate 23, and an upper polarizer 24 that are sequentially stacked from bottom to top above the backlight module. The lower substrate 22 is longer than the upper substrate 23 and extends outward to form a step. A driving IC 3 and an FPC 4 are bonded to the upper surface of the lower substrate 22 at the step. The FPC 4 extends outward, and an avoidance groove 14 for avoiding the FPC 4 is formed on the side wall 12 on the side where the FPC 4 extends outward.
[0035] Please refer to Figure 1 , as a further optimized solution of Embodiment 1, in this embodiment, at least two material extraction grooves 15 are formed by the upper surface of the bottom plate 11 recessing downward. The remaining material of the bottom plate 11 between adjacent material extraction grooves 15 forms a reinforcing rib 16. The bottom plate 11 located inside the side wall 12 extends upward to form a bearing portion 17. The bearing portion 17 is perpendicular to the bottom plate 11, and the height of the bearing portion 17 is lower than the height of the side wall 12; a light guide plate is provided on the bearing portion 17. A reinforcing rib 16 is formed between the material extraction grooves 15, which can not only prevent injection molding shrinkage and reduce materials, but also enhance the strength of the lower frame 1. Since the bottom plate 11 is also provided with a bearing portion 17, and the light guide plate is supported by the bearing portion 17. Since the bearing portion 17 is formed by the bottom plate 11 extending upward, its height is higher than the height of the bottom plate 11 and the reinforcing rib 16, so the light guide plate no longer directly contacts the reinforcing rib 16, thereby preventing the burrs on the reinforcing rib 16 from scratching the light guide plate. When the lower frame 1 is slightly deformed, its raised height can also prevent the reinforcing rib 16 from squeezing the light guide plate and prevent the light guide plate from being damaged. The backlight module provided by the present utility model can make the material extraction grooves 15 provided on the inner surface of the lower frame 1, which can make the backlight module more beautiful; it can also prevent injection molding shrinkage, reduce material consumption and strengthen the strength of the lower frame 1, and at the same time prevent the reinforcing rib 16 from damaging the light guide plate and avoid damage to the light guide plate.
[0036] Further, a chamfer is provided at the edge of the bearing portion 17, which can be a right chamfer or a rounded chamfer. The right chamfer and the rounded chamfer can remove burrs to prevent the burrs of the bearing portion 17 from scratching the light guide plate.
[0037] Further, the shape of the material extraction groove 15 is a polygon. More preferably, the shape of the material extraction groove 15 is a regular hexagon, which has better strength than the conventional rectangular-shaped lower frame 1.
[0038] Of course, the structure described in the present utility model is also applicable to a backlight module with one end of the light guide plate being thin and the other end being thick. The bottom plate 11 of the lower frame 1 can be inclined, and the bearing portion 17 extending upward from the bottom plate 11 also has an inclined surface with the same slope as the bottom plate 11. The material extraction groove 15 is provided on the bottom plate 11, and it can still prevent the reinforcing rib 16 formed by the material extraction groove 15 from damaging the light guide plate, and it should also fall within the protection scope of the present utility model.
[0039] In the present utility model, unless otherwise clearly stipulated and defined, terms such as "installation", "connection", "attachment", "fixation", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection, an electrical connection, or capable of communicating with each other; it may be directly connected, or indirectly connected through an intermediate medium, and it may be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0040] Obviously, the embodiments described above are only a part of the embodiments of the present application, rather than all the embodiments. The accompanying drawings show the preferred embodiments of the present application, but do not limit the patent scope of the present application.
