As part of the "urban lighting" of big cities, the outdoor LED display on the street that flickers day and night adds a lot of movement and color to the big city, and it also produces environmental pollution. In recent years, following the development trend of commercial services, the environmental pollution of light radiation caused by outdoor LED display screens around the commercial circles of big cities has caused increasing reports from the masses. Especially as government departments attach great importance to safe production work and households have improved the natural environment regulations for settlement, the problem of environmental pollution can no longer be ignored.

The "Environmental Protection Law" requires that institutions and institutions that discharge air pollutants should take effective measures to prevent environmental pollution and harm to the natural environment caused by light radiation that is often caused in manufacturing infrastructure or other themed activities. Since the first case of "environmental pollution" prosecution in Qingdao in 2002, "environmental pollution" has become a problem that every LED manufacturer must deal with and deal with. Although the original lawsuit ended in a lawsuit by the appellant, it did not It does not imply that the main responsibility constructor of the LED display has no obligation. On December 28, 2018, Wang and others in Jiangjin District, Chongqing City filed a lawsuit against the environmental pollution of the outdoor LED display. They once again produced and produced many outdoor LEDs. The supplier has sounded the alarm, reminding manufacturers that they do not need to pursue chroma one-sidedly, which leads to additional costs and environmental pollution.

Therefore, in the future development, manufacturers of outdoor led display screens must carry out production and manufacturing according to relevant specifications, and comprehensively improve product characteristics, so as to exceed the purpose of rationally controlling environmental pollution of led display screens. And starting from the product itself, product research and development can deepen the outdoor display information product that reduces the pain to human eyes. In fact, from the technical level of LED display, many products can guarantee the system to adjust the chromaticity, which can be adjusted automatically according to different natural environments, and the multi-level true color correction technology is much better, and the intensity of the color is improved. , So that everyone can experience the gentle color when watching. This can greatly improve the "environmental pollution" situation in large cities with large LED screens, but the most important thing is the standardization of management methods and the operability of their implementation. In the future, people will have to cultivate again to make the outdoor LED display truly progress. To the standardization period.
