Causes and Countermeasures of light pollution of LED display screen

LED display since there has been a is based on energy saving and environmental protection is important, but in recent years, with the popularity of the LED display, but the concept of "light pollution". So in the end LED display is not light pollution?

According to the international definition of light pollution, usually divided into 3 categories: white pollution, artificial daylight and color 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 feel unwell, should belong to the light pollution". Our products in the design of the display screen has been considering the light pollution prevention and control of the display screen.

In order to prevent light pollution, first of all, we first summarize the reasons for its shape, usually caused by the following aspects:

1, LED display area is too large, resulting in curtain wall visual barrier.

2, the contents of the LED screen display excessive commercialization caused by watching the crowd refused to see the psychological.

3, the installation position and area of the screen is not suited to watch the crowd psychology.

4, high brightness of the LED display screen, resulting in sharp contrast with the surrounding environment. Cause people to adapt to local high brightness.

According to the reasons for formation, our products have taken the corresponding solutions.

1, rational planning of the display area and installation location

According to the viewing distance and viewing angle, as well as the surrounding environment, as well as the contents of the display requirements, the rational planning of the display area and location. Rather than blindly pursue large area, significant position.

2, broadcast content selection and design

Large screen display is a public media, public welfare, advertising, instructions, etc.. We choose to play the content, must be consistent with the requirements of the public to avoid refusing to see the psychological.

3, multi-level gray correction technology to improve color softness.

Our LED display products use more gray level, so that color looks soft color, the transition of natural.

4, the system can automatically adjust the brightness adjustment system

The brightness changes in different time and place environment greatly, if the brightness of the display is greater than the environment too much, not to cause people's eyes, especially the luminance difference of day and night is relatively large, causing light pollution, automatic brightness adjustment system we can automatically change the brightness is suitable for broadcast environment, avoid light pollution.

Relative neon and white light box advertising and other products, LED display has greatly reduced the light pollution, in order to enrich our visual space, light up a better life, we will work harder.
