Since its appearance, LED displays have been valued for their energy saving and environmental protection. However, with the popularity of LED displays in recent years, the concept of “light pollution†has been raised. So in the end, is the LED display considered "light pollution"? According to the current international definition of light pollution, it is usually divided into three categories: white bright pollution, artificial chalk and color light pollution. At present, China only has regulations on the glass curtain wall in Bailiang pollution, and there is no relevant regulation on artificial chalk and color light pollution. However, considering that color light pollution does cause people to feel uncomfortable, it should belong to "light pollution." Our products always consider the problem of light pollution prevention of the display screen when designing the display screen. To prevent smelting pollution First, let us first summarize the reasons for its shape, usually caused by the following aspects: 1, the LED display area is too large, resulting in a curtain wall-type visual barrier. 2. The content of the LED display is over-commercialized, resulting in the rejection of the viewing crowd. 3. The installation position and area of ​​the display screen are not suitable for the psychology of watching the crowd. 4, the high brightness of the LED display surface, resulting in a sharp contrast with the surrounding environment. Causes people to adapt to local high brightness. According to the reasons for the formation, our products have adopted corresponding solutions. 1. Reasonably plan the display area and installation position According to the viewing distance and viewing angle as well as the surrounding environment, as well as the requirements of the display content, the display area and location are reasonably planned. Rather than blindly pursuing an area that is large and prominent. 2. Selection and design of playback content Large-scale giant display screens are public media, and there are public welfare, advertising, and instructional categories. When we choose to play the content, we must agree with the public request to avoid refusal. 3, multi-level gray correction technology to improve color softness. Our LED display products use more grayscale levels to make colors look softer and transitional. 4, using a system that can automatically adjust the brightness adjustment system The brightness of the environment varies greatly at different times and places. If the display brightness of the display is greater than the environment, it will cause people's eyes to be uncomfortable, especially the difference in brightness between day and night, causing light pollution, our automatic brightness adjustment. The system automatically converts the broadcast brightness suitable for the environment to avoid light pollution. Relative to the neon and white light box advertising products, LED display has greatly reduced the light pollution, in order to enrich our visual space, to light a good life, we will work harder.
