Problems solved by technology

In order to sell products, merchants often use various methods for advertising. At present, the application of print advertising equipment has become very common. There are traditional advertising light box equipment and various electronic advertising devices. Shopping malls, stations, airports can be seen everywhere, and indoors A large number of LCD screens or touch screens are also used for advertising display and human-computer interaction, and the publicity effect is remarkable, but this is only for indoor display and advertising

[0003] If you use the LCD screen for display outdoors, although the display effect is remarkable, because the LCD screen is exposed to the outside for a long time, its surface is easy to accumulate dust or form large water stains, and it needs to be cleaned frequently. However, because outdoor LCD screens are generally set in The high position makes manual cleaning very inconvenient, which in turn increases the cost of manual maintenance. If it is not cleaned for a long time, it will directly affect the display effect of the LCD screen, and even affect its heat dissipation effect

[0004] In addition, because the LCD screen is exposed to the outside for a long time, it is easy to damage the LCD screen and its supporting equipment when encountering strong winds or stormy weather, which will greatly shorten the service life of the LCD screen and its supporting equipment, and frequently update equipment, which will increase the cost of advertising.
