Outdoor LED Sign Display: How To Avoid Light Pollution?

Shenzhen Lights Technology Co.,Ltd | Updated: Apr 10, 2017

Internationally general LED display light pollution is divided into three categories, namely white light pollution, artificial daylight and IPL pollution. At present, there is no relevant requirement for artificial daytime and IPL pollution. But taking into account the IPL pollution does cause people feel uncomfortable, so in the design led display screen to be taken into account the screen light pollution prevention and control issues.

1. Using the automatical 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 environment brightness collection. Display flat control system through the receiving system data automatically converted by software for the environment broadcast brightness.

2. Using 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.

3. Choosing a rightful installation location and a reasonable arrangement of area

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.

4. The appropriate selection and design of contents.

LED display 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.

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 requirements do 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 energy-saving and rich color advantages, will be a comprehensive alternative to neon lights, information display.
