But we can use the automatic brightness adjustment system, so that the broadcast brightness suitable for the environment can be automatically converted, so as to achieve the effect of avoiding light pollution on the outdoor LED display.

　What can be done to better reduce the light pollution of outdoor LED displays? We all know that with the development of science and technology, the pollution on the earth will become more serious. Of course, the pollution of the LED display is also in it. So how can we better avoid light pollution and let the outdoor LED display show its real advantages? At present, Lianchengfa has the following methods:

1. LED display area and installation location

　　 According to the viewing distance and the viewing angle of the environment, reasonably plan the area and position of the display screen. The installation of the display screen must be maintained at a certain inclination and a certain relative height. When the inclination of the display screen to the vertical is less than 45°, this will be more in line with people's viewing angle, and it will also be able to better reduce the direct light of the display screen and the influence of escaping light on the surrounding environment. The display screen is installed at a height within ten meters from the ground, which can better reduce a major impact of astigmatism and direct light on the environment.

　　 2. Control the brightness of the LED display

We all know that the brightness of the surrounding environment at night will be relatively low, and many people will also reduce the brightness of the LED display at night through brightness adjustment technology, so we have to adjust a brightness at this time, and restore the design brightness during the day. It does not affect the effect of the LED screen, it also reduces the light pollution of the LED display at night, and it also saves an electric energy for the display.

　　3. Reasonably design the broadcast content

Since the light pollution of the LED display screen is closely related to the color of the display, it is necessary to use high-purity colors when designing to play movies, use mixed colors, and use low-purity and high-brightness colors as the main color as little as possible; the previous video and the next The transfer between videos should be slow but not urgent; don't use images that flicker too much.

　　4. Automatic brightness adjustment system

　　 We also know that environmental brightness changes at different times are relatively large. If the brightness of the display is greater than that of the environment, especially at night, the strong light will cause discomfort to people’s eyes or Shanghai. But we can use the automatic brightness adjustment system, so that the broadcast brightness suitable for the environment can be automatically converted, so as to achieve the effect of avoiding light pollution on the outdoor LED display.
