LED display pollution control editing
Internationally general LED display light pollution is divided into three categories, namely white light pollution, artificial daytime and IPL pollution. At present, China only white light pollution in the glass curtain wall has the relevant provisions of the artificial daylight and IPL pollution is now no relevant provisions. But taking into account the IPL pollution does cause people feel discomfort, so in the design of LED display screen to take into account the display screen light pollution prevention and control issues.
First, the system can automatically adjust the brightness adjustment system
We know that day and night, different times and places the brightness of the environment changes greatly, if the LED display brightness is greater than the ambient brightness of 60% we obviously feel the eyes do not meet, that is caused by the light pollution to people. Through the outdoor brightness collection system, at any time on the ambient brightness collection. The display control system automatically converts the broadcast brightness suitable for the environment by receiving the system data.
Second, multi-level gray correction technology
Ordinary display system uses 8bit color display level, so that in some low gray and color over the color blunt. Will also cause color light does not meet. The new LED large screen control system uses 14bit color display level, greatly improving the color in the excessive hardness. So that people can feel soft when watching. To avoid people's discomfort to light.
Third, the installation of a reasonable choice of location and display area of the rational planning
Viewing distance and viewing angle with the display area has an empirical plan, while the image study in the display viewing distance and viewing angle has specific design requirements. In the design of the display should be as much as possible to meet the design requirements, reasonable planning.
Fourth, the content of the selection and design
LED large screen is the public media, there are public class, advertising category, 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.
LED diode itself is a green light source, although the use of large-scale LED large-scale display on the screen because of the design considerations and the use of the request does cause a certain degree of IPL pollution, but this contradiction is inevitable, and Can not be completely eradicated. Only the use of technical means and policies and regulations to minimize the IPL pollution, coordination of the needs of advertisers and people's viewing psychology. At the same time, we also see the relative current neon and white light box advertising, LED display light pollution is already greatly reduced. And LED electronic display also has the advantages of energy saving and rich colors, will be a comprehensive alternative to neon outdoor lighting, information display.
