The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0034] Example 1. Please refer to Figures 1 to 3 , a liquid crystal display screen convenient for FPC6 insertion provided by the present utility model, which includes a lower iron frame 1, a main board 2, a backlight module 3, and a display module 4. The lower iron frame 1 includes a bottom plate 11 and a side wall 12 extending upward from the edge of the bottom plate 11; the main board 2 is disposed on the lower surface of the bottom plate 11, and a ZIF connector 5 is provided on the main board 2; the backlight module 3 is disposed on the upper surface of the bottom plate 11; the display module 4 is disposed above the backlight module 3, an FPC6 is led out from the display module 4, a gold finger 7 corresponding to the ZIF connector 5 is provided on the FPC6, the FPC6 is bent to the lower surface of the main board 2 and connected to the ZIF connector 5 through the gold finger 7, a reinforcing plate 8 is disposed on the outer surface of the FPC6 at the position of the gold finger 7, at least one handheld insertion handle 9 extends outward from the reinforcing plate 8, and the handheld insertion handle 9 extends to the outside of the FPC6. Since the reinforcing plate 8 extends outward with the handheld insertion handle 9, when it is difficult to insert from the front, the assembly insertion can be performed by holding the handheld insertion handle 9 on the side. The shape of the handheld insertion handle 9 on the side can be adjusted to different positions and different shapes according to different application requirements. The handheld insertion handle 9 can facilitate the insertion of the FPC6, reduce the assembly difficulty, and improve the assembly efficiency, so as to further improve the competitiveness of the product.

[0035] Further, an arc notch 91 is provided at the edge of the handheld insertion handle 9 close to the FPC6, and the arc notch 91 is located on the side close to the gold finger 7. The arc notch 91 can avoid stress concentration here, thereby avoiding damage to the handheld insertion handle 9 during insertion.

[0036] Further, there are two handheld insertion handles 9 and they are respectively disposed on both sides of the reinforcing plate 8 to reduce the assembly difficulty and improve the assembly efficiency.

[0037] Example 2. Please refer to Figures 4 to 7, as a further optimized solution of Embodiment 1, in this embodiment, at least one retaining wall 13 is stamped on the top and bottom of the lower surface of the bottom plate 11. The retaining wall 13 is perpendicular to the bottom plate 11. At least one twisting foot 14 is stamped on the left and right sides of the lower surface of the bottom plate 11. In this embodiment, there are four retaining walls 13, with two retaining walls 13 provided on both the top and bottom of the bottom plate 11, and there are four twisting feet 14, with two twisting feet 14 provided on both the left and right sides of the bottom plate 11. In other embodiments, the number and position of the twisting feet 14 are required to be evenly distributed to achieve the limiting and fixing effects. The twisting feet 14 can rotate, and the main board 2 is placed in the space defined by the retaining walls 13 and the twisting feet 14. Since at least one retaining wall 13 is stamped on the top and bottom of the lower surface of the bottom plate 11, and at least one twisting foot 14 is stamped on the left and right sides of the lower surface of the bottom plate 11, the twisting feet 14 and the retaining walls 13 are provided on the bottom plate 11 by means of die stamping. The main board 2 is limited by the retaining walls 13, and the main board 2 is fixed by rotating the twisting feet 14. The assembly reliability of the main board 2 can be improved without affecting the cost, and the main board 2 can be prevented from falling off.

[0038] Further, the width of the retaining wall 13 is 8 mm to 12 mm. The assembly gap between the retaining wall 13 and the main board 2 is 0.3 mm to 0.5 mm. The height of the retaining wall 13 is the same as the thickness of the main board 2.

[0039] Further, in order to enable the twisting feet 14 to best match the main board 2 and perform bending and twisting fixation, the cross-sectional shape of the twisting feet 14 is L-shaped. The twisting feet 14 include a root portion 141 and a twisting portion 142. The root portion 141 is connected to the bottom plate 11, and the twisting portion 142 is connected to the root portion 141.

[0040] Further, the width of the root portion 141 of the twisting feet 14 is 4 mm to 6 mm to ensure that the root portion 141 has sufficient strength.

[0041] Further, the width of the twisting portion 142 of the twisting feet 14 is 4 mm to 6 mm to ensure that there is sufficient length for the twisting portion 142 to press on the main board 2 after bending and twisting. The assembly gap between the twisting portion 142 and the main board 2 is 0.3 mm to 0.5 mm.

[0042] Further, an inner concave portion 143 is provided at the connection between the inner sides of the root portion 141 and the twisting portion 142. The inner concave portion 143 has a smooth transition to avoid stress concentration.

[0043] Further, the depth of the inner concave portion 143 is 0.5 mm to 1.0 mm, and the distance from the deepest point of the inner concave portion 143 to the lower surface of the root portion 141 is 1.5 mm to 2.5 mm. To avoid the problem that the width at this position is too thin and the twisting feet 14 are prone to breakage when bending and twisting. The assembly gap between the twisting feet 14 and the main board 2 is 0.3 mm to 0.5 mm.
