It is a device used to display various information such as text, images, videos, etc. LED electronic display integrates microelectronics technology, computer technology, and information processing. It has the advantages of bright colors, wide dynamic range, high brightness, long life, stable and reliable operation, etc.

[0003] At present, the LED outdoor advertising screens on the market are widely used in many places, such as shopping malls and street shops, and are usually used outdoors.

[0004] The patent document with the prior art announcement number CN213089226U provides a technical solution: an LED outdoor advertising display screen, comprising a top column, a middle column and a bottom column, wherein a shock-absorbing box is fixedly installed at the bottom end of the bottom column, and an LED display screen is fixedly installed at the bottom end of the shock-absorbing box, a bearing is fixedly installed on the right side of the inner wall of the middle column, a rotating nail is movably connected to the left side of the bearing, and a knob is fixedly installed on the left side of the rotating nail, and a first slide groove is opened on the inner wall of the middle column. The LED outdoor advertising display screen is used in conjunction with a stabilizing box and a rotating nail, so that when the middle column enters the top column and the bottom column, the card block shrinks into the stabilizing box, and when the middle column completely enters the top column and the bottom column, the third spring pushes the card block into the elliptical groove of the rotating nail. Since stabilizing boxes are provided below the top column and above the bottom column, and rotating nails are provided at the top and bottom ends of the middle column, the middle column can be stably connected with the top column and the bottom column to prevent the middle column from moving left and right and falling off.

[0005] but:

[0006] When used outdoors, dust can easily contaminate the surface of the LED display. As dust accumulates, the display effect of the LED display will be affected and needs to be cleaned regularly. The traditional cleaning method is manual cleaning, which is more troublesome. Utility Model Content
