At present, bacteria and fungi in the environment are easy to breed and cover the surface of the touch screen due to the fact that the touch screen has no sterilization function. As these organisms metabolize, they produce chemical by-products that can attack the touch screen, reducing its sensitivity and creating odors. In addition, a certain number of colony cages can also affect the optical performance of the touch screen and irreparably damage the touch screen. Meanwhile, most of the touch screens are placed in public places and need to be in direct contact with operators, so that dust and various bacteria can be accumulated on the touch surface of the touch screen body, and when different operators use the touch screens, the bacteria can be spread among different operators, so that a public bacteria source is formed, and the bacteria prevention of the touch screens becomes a problem to be solved urgently.
At present, some technologies for performing antibiosis by coating on the surface of a touch screen have been developed in the field, and generally, the surface of the touch screen is subjected to coating processing to form a protective film so as to achieve the antibacterial effect.

However, the above-mentioned techniques have the following disadvantages in practical applications: firstly, the technologies can only passively resist bacteria but cannot actively kill bacteria; secondly, the coating layer can not be used durably, and the antibacterial coating on the surface of the touch screen can be damaged after multiple times of touch, so that the antibacterial effect is invalid after the touch screen is used for a period of time; thirdly, the coating process is complex, the efficiency is low, the coating can be finished by spraying, coating and baking for many times, and the requirements on the cleanliness of the environment, the temperature and equipment facilities are high; and fourthly, the used stock solution, the used liquid medicine and the preparation process have certain pollution to the environment, so the national management and the requirement on related production units are extremely high, and the efficiency and the price of the antibacterial treatment product of the direct coating process are influenced to a certain extent.
