Light pollution solution
First, the system can automatically adjust the brightness adjustment system
Day and night, different time and place environment brightness varies greatly, if the LED display playback brightness greater than 60% of the ambient brightness we obviously feel the eye does not meet, that is to say, causing light pollution to humans. Through the outdoor brightness acquisition system, the ambient light collection at any time. Display control system by receiving system data automatically converted by the software broadcast brightness for the environment.
Second, multi-level gray-scale correction technology
Ordinary display system uses 8bit color display level, so that in some low-gray and over-color at the color blunt. Will also cause color light does not meet. The new LED screen control system uses 14bit color display level, greatly improving the color over the hardness. Make people feel soft when watching. Avoid people feeling uncomfortable with light.
Third, the reasonable choice of the installation location and display area of a reasonable plan
Viewing distance and viewing angle with the display area has a plan of experience, while the image display in the viewing distance and viewing angle have specific design requirements. In the display design should be as much as possible to meet the design requirements, rational planning.
Fourth, the choice of content and design
LED screen is the public media, there are public welfare, advertising, instruction and so on. When we choose to play the content, we must agree with the public request to avoid refusing to look psychologically. This is also an important aspect of light pollution prevention and control.
LED diode itself is a green light source, although in the clusters of large-scale giant LED display screen because of the design considerations and the use of the requirements indeed caused a certain degree of IPL pollution, but this contradiction is inevitable, and It is impossible to eradicate completely. Only the use of technical means and policies and regulations to minimize IPL pollution, coordinating the needs of advertisers and the public viewing psychology. At the same time, we also see the relative light neon and white light box advertising, LED light pollution has been greatly reduced. And LED electronic display also has the advantages of energy saving and color rich, is bound to be a comprehensive alternative neon lights, information display.
