At present, the light pollution of LED display screens is generally divided into three categories in the world, namely, white light pollution, artificial daylight pollution and color light pollution. At present, my country only has relevant regulations on the glass curtain wall in the pollution of white light, and there are no relevant regulations on artificial daylight and color light pollution. However, considering that color light pollution does cause people to feel uncomfortable, it is necessary to consider the prevention and control of display screen light pollution when designing LED display screens. 1. Using a brightness adjustment system that can be automatically adjusted by the system. We know that the brightness of the environment varies greatly during the day and night, at different times and locations. If the playback brightness of the LED display is greater than 60% of the ambient brightness, we will obviously feel the eyes. Not adapting, which means that it causes light pollution to people. Through the outdoor brightness collection system, the ambient brightness can be collected at any time. The display level control system automatically converts the broadcast brightness suitable for the environment through the software by receiving the system data. 2. Multi-level gray-scale correction technology The 8-bit color display level used by the ordinary display system, so that the color is stiff at some low gray levels and excessive color. It will also cause inadaptability of colored light. The new LED large-screen control system uses 14bit color display levels, which greatly improves the hardness of the color. So that people can feel the color soft when watching. Avoid people’s discomfort with light. 3. Reasonable choice of installation location and reasonable planning of display area. There is an empirical plan for viewing distance and viewing angle and display area. At the same time, image research is specific in display viewing distance and viewing angle. Design requirements. When designing the display screen, the design requirements should be met as much as possible, and the planning should be reasonable. Fourth, the selection and design of the content to be played. The large LED screen is a public medium, including public welfare, advertising, and instruction. When we choose the content to be broadcast, we must reach an agreement with the public's requirements to avoid the mentality of refusal to watch it. This is also an important aspect of preventing and controlling the light pollution of the display screen. The LED diode itself is a green light source. Although the large-scale giant LED display screen used in clusters does cause a certain degree of color light pollution due to design considerations and application requirements, this contradiction is inevitable, and It cannot be completely eradicated. Only by adopting technical means and policies and regulations to minimize color light pollution, and to coordinate the needs of advertisers and the people's viewing psychology. At the same time, we have also seen that compared with today's neon and white light box advertisements, the light pollution of LED displays has been greatly reduced. Moreover, the LED electronic display has the advantages of energy saving and rich colors, and it will definitely replace the neon light outdoor lighting and information display.
