LED large screen to prevent light pollution has become a public criticism, but led the big screen playback brightness does not exceed 60% of the ambient brightness, the human eye will be less damage. In addition, you can also set the brightness of the led display, installation of the place and angle, playback time, the size of the size of the restrictions and other technical means to reduce light pollution.
Four ways to reduce light pollution
1. The automatic adjustment of brightness adjustment system: through the outdoor brightness collection system, at any time on the environmental brightness of the data acquisition, display control system will receive the collected data through software analysis, automatically adjust the environment for the broadcast brightness.
2. Multi-level gray-scale correction technology: the use of 14bit color display level of the new led large screen control system to replace the ordinary display system using 8bit color display level, so that people can feel when watching the soft color, to avoid ordinary display Screen in some low gray and excessive color, the phenomenon of blunt color so that people have a sense of discomfort to light.
3. Reasonable choice of installation location and reasonable planning of the display area: viewing distance, viewing angle and display area to have a specific design requirements, in the display design should be as much as possible to meet the design requirements, reasonable planning.
4. Play content selection and design: led large screen is the public media, there are public class, advertising class, instructions and so on. When we choose to play the content, we must agree with the public requirements, to avoid refusing to see the psychological. This is also an important aspect of prevention and control of light pollution.
Read the above several ways to reduce light pollution, in fact, is not too difficult technology off, we are too much to pursue LED large screen screen brightness caused by, in fact, led the big screen playback brightness does not exceed 60% The stimulation of the human eye becomes limited, reducing the light pollution to the whole environment.
