Problems solved by technology

Multi-screen interactive LCD displays are also widely used in various exhibition halls. Visitors who come here can better participate in the exhibition by knowing the information they need on the multi-screen interactive LCD displays; but this type of display All are touch-screen operations, and there are many people in the exhibition hall. Using the display screen at the same time will not only pollute the display screen due to a large number of fingerprint traces, but also the display screens in the exhibition hall under the existing technology do not have the function of disinfection and sterilization, so that people pass fingerprints Indirect contact, in the current environment where the new crown epidemic is still raging, it is easy to cause human-to-human contact infection, which greatly increases the risk of epidemic spread
