Many people complain that the LED advertising display is too glaring, and the frequent flashing picture is easy to distract the driver's attention, and sometimes the sudden glare on the display will make the driver feel dizzy, resulting in Visual interference poses a safety hazard to driving.
There are also LED display screens near some residential buildings. Some residents not only suffer from noise pollution, but also fall into the troubles of light pollution. Some people's windows are just facing the advertising screen, and it is difficult to sleep in the room in the middle of the night.
Excessive outdoor brightness will lead to light pollution, which is already recognized as the fifth largest killer of the environment in the world. For this problem, the staff of the environmental protection department of Changchun City said that because there are no relevant laws and regulations in China, there is no way to define light pollution. The standard is therefore difficult to manage light pollution.
Industry insiders suggest that relevant departments should strengthen the planning and management of outdoor large-scale LED advertising color screen design, strictly approve and rationalize the layout, and standardize the size of LED advertising color screens. Color screen settings should be considered as far as possible from urban main roads, and the plane of color screen should be as far as possible. Parallel to the road, traffic intersections should not be set as much as possible. At the same time, we should consider controlling the display brightness of the LED advertising display, as well as the playing time and the rhythm of the picture playback, to minimize the impact of color screens on traffic safety and urban residents' lives.
