Description

technical field [0001] The invention relates to a display screen, in particular to an outdoor easy-to-clean LED display screen. Background technique [0002] The LED display is composed of small LED module panels. LED displays are generally used to display various information such as text, images, videos, and video signals. The reason why LED has been widely valued and developed rapidly is inseparable from its own advantages. These advantages are summarized as follows: high brightness, low operating voltage, low power consumption, large size, long life, impact resistance and stable performance. The development prospect of LED is very broad, and it is developing towards higher brightness, higher weather resistance, higher luminous density, higher uniformity of luminous light, reliability, and full color. LED displays are widely used in advertising in sports venues, commercial applications, banks, securities, postal services, docks, shopping malls, stations, postal services...

AI Technical Summary

Problems solved by technology

While maintaining brightness, the LED display also has disadvantages, that is, in rainy days, the LED display is wetted by rain, and people's eyes can easily induce eye diseases and shed tears when they face the display screen at close range for a long time. This kind of light source pollution, at the same time, the general outdoor LED display screen is hung at a high place, it is time-consuming and labor-intensive to clean, it requires high labor, and it is prone to danger and affects the safety of cleaning personnel.
