LED display screens can be seen everywhere in our lives and continue to provide us with various conveniences. In recent years, the problem of "light pollution" has been paid attention to by people; light pollution is mainly divided into white pollution, artificial daytime pollution and color light pollution, which threaten people's Healthy; Therefore, we should consider the prevention and control of large-screen light pollution when we initially design the LED display.

1. Adopt a brightness adjustment system that can be automatically adjusted by the system
We know that the brightness of the environment at different times and locations varies greatly during the day and night. If the playback brightness of the LED display is greater than 60 percent of the ambient brightness, we will obviously feel that the eyes are not adapted, 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 grayscale correction technology
The 8bit color display gradation adopted by the ordinary display screen system, so that the color is stiff in some low grayscale 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 colors. 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, and image research has specific design requirements for display viewing distance and viewing angle. 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 display 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.
Everything is multi-faceted. Just like the LED display, while serving our lives and providing convenience, it will also bring more or less other impacts. It should be controlled as much as possible during use to make it effective. To maximize, continue to serve us better.
