Explore the solution of LED display light pollution problem

The general LED display light pollution is divided into 3 categories, namely white light pollution, daylight and artificial light pollution. At present, our country only white light pollution in the glass curtain wall of the relevant provisions of the artificial daylight and color light pollution is not relevant provisions. However, taking into account the color light pollution does cause people to feel uncomfortable, so in the design of LED display screen should take into account the problem of light pollution prevention.

First, the system of automatic adjustment of brightness adjustment system

We know the day and night, brightness changes in different time and place environment greatly, if not to play LED screen brightness greater than ambient brightness 60% we clearly feel the eyes, that is caused by light pollution on people. Through the outdoor brightness acquisition system, the environmental brightness. The display level control system automatically converts the brightness of the environment to the environment by receiving the data of the system.

Two, the multi-level gray correction technology

Ordinary display system uses the 8bit color display level, so that some low gray and color over the color of the blunt. Will also cause color light adaptation. The new LED large screen control system uses 14bit color display level, greatly improving the color on the excessive hardness. So that people can feel soft when watching, to avoid people's discomfort to light.

Reasonable planning reasonable choice of three, the installation location and display area

Viewing distance and viewing angle have an experience plan with the display area, while the image research has specific design requirements on the viewing distance and viewing angle of the display screen. In the design of the screen should be as much as possible to meet the design requirements, reasonable planning.

Four, to play the content selection and design of

LED large screen is a public media, public welfare, advertising, instruction class, etc.. We choose to play the content, must be consistent with the requirements of the public to avoid refusing to see the psychological. This is also an important aspect of light pollution prevention and control.

LED diode itself is a green light source, although in the cluster using LED large display screen for consideration and application in the design of the requirements is indeed caused by the light pollution to a certain extent, but the contradiction is inevitable, and can not be completely eradicated. Only by means of technical means and policies and regulations to minimize the pollution of color light, and to meet the needs of advertisers and people's psychological watch. At the same time, we also see today's neon light and white light box advertising, LED display light pollution has been greatly reduced. And LED electronic display also has the advantages of energy saving and rich colors, will be a comprehensive alternative to neon lighting, information display.
