How to Solve the Light Pollution of LED Display?

In the world, LED display light pollution is generally divided into three categories, namely white light pollution, artificial daylight and color light pollution. At present, there is no relevant regulation on artificial chalk and color light pollution. However, we consider that the pollution of color light cause people to feel uncomfortable, it is necessary to consider the problem of prevention and control of light pollution on the LED display screen when designing the LED display screen.

1. Adopting brightness automatic adjustment system

We know that during the day and night, the brightness of the environment varies greatly at different times and places. If the brightness of the LED display is greater than 60% of the ambient brightness, we obviously feel the discomfort of the eyes, which means that it causes light pollution to people. Through the outdoor brightness acquisition system, the ambient brightness is collected at any time. The LED display control system automatically converts the broadcast brightness suitable for the environment through software by receiving system data.

2. Technology of multi-level grayscale correction

The ordinary LED display system uses an 8-bit color display level, so that the color is hard at some low gray levels and excessive colors. It also causes the incompatibility of colored light. The new LED large-screen control system uses a 14-bit color display layer, which greatly improves the hardness of the color in excess,and make people feel soft when watching. Avoiding people's discomfort with light.

3. Reasonable selection of installation location and reasonable planning of LED display area

There is an empirical plan for viewing distance and viewing angle and display area, while image research has specific design requirements for viewing distance and viewing angle of the LED display screen. When designing the LED display screen, it should meet the design requirements as much as possible and plan properly.

4. Selection and design of playback content

LED display screen is a public media, there are public welfare, advertising, instructions and so on. When we choose the content for playing, we must agree with the public request to avoid refusal. This is also an important aspect of preventing LED display light pollution.

The LED diode itself is a green light source. Although it is caused some degree lighting polution by a design consideration and application requirements on the large-scale LED display screen of the cluster type, this kind of contradiction is inevitable, and Can not be completely eradicated. Only by using technical means and policies and regulations to minimize the pollution of color light, coordinate the needs of advertisers and the public's viewing psychology. At the same time, we also see that compared to today's neon and white light box advertising, the light pollution of LED display has been greatly reduced. And the LED electronic display also has the advantages of energy saving and rich color, and it will definitely replace the neon outdoor lighting and information display.
