In addition, the screen shielding function is also widely used in scenes to prevent information leakage. In some industries, such as finance, medical care and national defense, information security is very important. Shielding function can effectively protect sensitive information and prevent leakage. For example, patient information in hospitals and transaction data in banks need to be protected, and the use of shielding function can ensure the security of data.
In certain scenes such as flight, the shielding function of the screen is also of great significance. During the flight, there may be many interference factors, such as cell phone signals, lightning, etc., which may pose a threat to the aircraft. By shielding the screen, the interference to the instrument can be avoided and the flight safety can be ensured. At the same time, by shielding the passenger's screen, it can also ensure the comfort of passengers during the flight and avoid disturbing others.
