[0027] The utility model provides a liquid crystal display screen for improving the shockproof performance of the whole machine, which comprises a display module, a first optical adhesive layer, a first touch film, a second optical adhesive layer, a second touch film, a third optical adhesive layer and a cover plate which are sequentially stacked from bottom to top, wherein the first touch film is fully bonded to the top of the display module through the first optical adhesive layer, the second touch film is fully bonded to the top of the first touch film through the second optical adhesive layer, the cover plate is fully bonded to the top of the second touch film through the third optical adhesive layer, and the second touch film extends to the edge of the lower surface of the cover plate.

[0028] Since the second touch film extends to the edge of the lower surface of the cover plate, only the gap of the fitting tolerance is required. In this way, when the whole device and the edge of the cover plate are hit, the second touch film is soft and can offset part of the impact force, so that the edge of the cover plate is also well protected, improving the shockproof performance of the whole device.

Since the second touch film 4 extends to the edge of the lower surface of the cover plate 6, only the spacing size of the bonding tolerance is retained. In this way, when the edge of the whole machine and the cover plate 6 are hit, the second touch film 4 is soft and can play a role in offsetting part of the impact force, so that the edge part of the cover plate 6 is also well protected, thereby improving the shockproof performance of the whole machine.

[0032] Furthermore, the first touch film 2 extends to the edge of the second touch film 4 to further offset the impact force and improve the shockproof performance of the whole device.

[0033] Example 2

[0034] See also Figure 1 and Figure 3As a further optimization scheme of Example 1, in this embodiment, the display module 100 is bound with FPC7, and FPC7 includes a main body 71, an upper reinforcing plate 72 and a connector 73. The upper reinforcing plate 72 is fixed to the upper surface of the main body 71, and both ends of the upper reinforcing plate 72 have fixed parts 74 extending outward, and the two fixed parts 74 are both beyond the edge of the main body 71. The lower surfaces of the two fixed parts 74 are fixed with first strong magnetic blocks 75; the connector 73 is arranged below the main body 71, and two second strong magnetic blocks 76 corresponding to the two first strong magnetic blocks 75 are fixed on the connector 73. Since the upper surface of the body 71 is fixed with an upper reinforcing plate 72, both ends of the upper reinforcing plate 72 are fixed with first strong magnetic blocks 75, and the connector 73 is fixed with two second strong magnetic blocks 76 corresponding to the two first strong magnetic blocks 75, when the body 71 and the connector 73 are installed, as long as the two ends of the body 71 are close to the connector 73, the first strong magnetic blocks 75 at both ends of the body 71 and the second strong magnetic blocks 76 at both ends of the connector 73 will attract each other and be fixed, and the body 71 and the connector 73 can be automatically aligned and tightly connected. This assembly structure of the FPC 7 has few assembly steps, and only needs The assembly of FPC7 can be achieved by bringing the main body 71 and the connector 73 close together. The assembly efficiency of FPC7 can be greatly improved, and the automatic assembly of FPC7 and the connector 73 can be easily realized. The fewer the assembly steps, the lower the probability of defective FPC7 during assembly, thereby avoiding the situation where the products assembled with it cannot work normally due to poor assembly, thereby avoiding abnormal operation of the product and reducing the defective rate of the product, thereby greatly reducing the production and manufacturing costs of FPC7, thereby improving the product competitiveness of FPC7, thereby meeting the company's growing quality requirements.

[0035] Furthermore, two grooves 77 are provided on the connector 73, and two second strong magnetic blocks 76 are respectively fixed in the two grooves 77, so that the fit between the main body 71 and the connector 73 is more compact, and the reliability of assembly is improved, thereby greatly reducing the production and manufacturing costs of FPC7, and further improving the product competitiveness of FPC7, so as to meet the company's growing quality requirements.

[0036] Furthermore, the edge of the groove 77 is provided with a chamfer, so that when the first strong magnetic block 75 is close to the second strong magnetic block 76, it can fall accurately into the groove 77 under the guidance of the chamfer, thereby improving the accuracy and reliability of assembly, thereby greatly reducing the production and manufacturing costs of FPC7, and further improving the product competitiveness of FPC7.

[0037] Furthermore, the outer dimensions of the second strong magnetic block 76 are larger than those of the first strong magnetic block 75, and the outer dimensions of the groove 77 correspond to those of the first strong magnetic block 75 and the second strong magnetic block 76, so that the second strong magnetic block 76 can be firmly fixed in the groove 77. Even if the suction force of the first strong magnetic block 75 is large, the second strong magnetic block 76 will not be sucked out, thereby improving the reliability of assembly, thereby greatly reducing the production and manufacturing costs of FPC7, and further improving the product competitiveness of FPC7, thereby meeting the company's growing quality requirements.

[0038] Furthermore, the depth of the groove 77 is equal to the sum of the thicknesses of the first strong magnetic block 75 and the second strong magnetic block 76, so that the assembly of the body 71 and the connector 73 can be smoothly fitted without leaving any gaps. More preferably, a buffer pad can be provided on the contact surface between the body 71 and the connector 73, and a buffer groove corresponding to the buffer pad is provided on the connector 73, so that the body 71 or the connector 73 can be cushioned during the fitting assembly to avoid damage to the body 71 or the connector 73. More preferably, the buffer pad is a rubber pad, which has good effect, low cost and high cost performance.

[0039] Furthermore, the materials of the first strong magnetic block 75 and the second strong magnetic block 76 are both NdFeB strong magnets, which have mature technology and high cost performance.

[0040] Preferably, a lower reinforcement plate is fixed to the lower surface of the main body 71, and the upper reinforcement plate 72 and the lower reinforcement plate are staggered with each other. When the main body 71 is pulled out, the pressure exerted by the upper reinforcement plate 72 and the lower reinforcement plate on both sides on the main body 71 is not on the same line segment, and the stress will not be concentrated on the same straight line during bending, thereby avoiding stress concentration and the problem of easy micro-breakage of the line at the main body 71, thereby improving product yield.

[0041] Furthermore, the two mutually staggered upper reinforcing plates 72 and lower reinforcing plates referred to in the utility model can be respectively arranged at two different positions; or the center point positions can be the same, but the widths of the upper reinforcing plates 72 and the lower reinforcing plates are different. It is sufficient to make the stress of the upper reinforcing plates 72 and the lower reinforcing plates not concentrated on the same straight line when they are bent, which can avoid stress concentration and the problem of easy micro-breakage of the line at the body 71, thereby improving the product yield. In this embodiment, the widths of the upper reinforcing plates 72 and the lower reinforcing plates are different, and their center points are on the same horizontal line, so that the edges of the upper reinforcing plates 72 and the lower reinforcing plates are staggered and not concentrated on the same straight line.

[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.
