In the prior art, in order to prevent the liquid crystal touch screen from being removed, the existing protection scheme is as follows: 1. the two ends of the touch screen are respectively connected with the FPC cables, the FPC cables are provided with safety signals, and the FPCs at the two ends of the touch screen are respectively fixed on the front shell to prevent the touch screen from being removed. If the touch screen is removed from the front of the device, the two FPCs need to be disconnected for removal, which can cause the security signal on the FPCs to be disconnected, triggering a security attack. The scheme has high requirements on liquid crystal and touch screens, needs to be customized with liquid crystal manufacturers, and is high in cost and inconvenient to supply. 2. A tearing-proof PTF is pasted between the bottom of the liquid crystal and the front shell, and if the liquid crystal is uncovered, the tearing-proof PTF can be broken, so that the security attack is caused. However, the tear-resistant PTF has low reliability and is not suitable for mass production and practical use. 3. According to the traditional POS liquid crystal contact protection scheme, on one hand, the liquid crystal is required to be small (only 2.4 inches or 2.8 inches), otherwise, the contact cannot be added on the back, so that the liquid crystal has faults of water ripple, yellowing and the like (the traditional POS also has faults within an acceptable range), and cannot be used; on the other hand, the liquid crystal must be mounted between the main board and the front case, and the liquid crystal is caught by the front case, preventing the liquid crystal from being pushed out by the contacts. These two limitations result in the inability of smart POS to touch liquid crystal and touch screen protection as with conventional POS.
