How to prevent light pollution in LED display？

A: First, the brightness adjustment system that can be automatically adjusted by the system is adopted

Day and night, different times and places of the brightness of the environment changes greatly, if the brightness of the LED display is greater than the brightness of the environment 60%, we obviously feel that the eyes are not adapted, that is to say, caused by light pollution to people. Through the outdoor brightness acquisition system, the ambient brightness is collected at any time. The display control system automatically converts the broadcast brightness suitable for the environment by receiving system data through software. 

Second, multi-level gray scale correction technology

Ordinary display systems use an 8-bit color display layer, so that the color is stiff at some low gray levels and color excesses. It will also cause discomfort of colored light. The new LED large-screen control system adopts a 14-bit color display level, which greatly improves the hardness of the color in excess. So that people can feel the color pastel when watching. Avoid people's discomfort with light. 

Third, the reasonable choice of installation location and reasonable planning of display area

The viewing distance and viewing angle have an empirical plan with the display area, and the image study has specific design requirements in the viewing distance and viewing angle of the display. In the design of the display, it should meet the design requirements as much as possible and make reasonable planning.

Fourth, the selection and design of playback content

LED large screen is a public medium, including public welfare, advertising, instructions and so on. When we choose the content to play, we must agree with the public's requirements and avoid rejection. This is also an important aspect of preventing and controlling light pollution on display screens.

LED diode itself is a green light source, although in the cluster use of LED large giant display screen because of the design considerations and application requirements did cause a certain degree of color light pollution, but this contradiction is inevitable, and can not be completely eradicated. Only by using technical means and policies and regulations to minimize color light pollution, coordinate the needs of advertisers and the public's viewing psychology. At the same time, we also see that compared with today's neon lights and white light box advertisements, the light pollution of LED displays has been greatly reduced. And LED electronic display also has the advantages of energy saving and rich color, will be a comprehensive replacement for neon outdoor lighting, information display.
