Moment, LED advertising machine display light pollution is usually divided into 3 categories, namely white pollution, artificial daylight and color light pollution. So, the application of daily advertising machine, how can we prevent LED ad display screen light pollution?

First, broadcast content selection and design

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

1, set reasonable content, such as commercial advertising and public welfare combination.

2, control playback time. For light pollution, one of the more effective way is to control the playback period.

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

Two, LED advertising machine display manufacturing enterprises: improve the technical level improve light pollution"

In general, the brightness of the sun is 2000CD, when the brightness exceeds two times the brightness of the sun, that is, 4000CD, the human body is completely visible on the naked eye. Outdoor LED advertising machine display brightness standard is 5000CD, and outdoor display brightness is more than 5000CD will be defined as light pollution. So to grasp the brightness settings.

1, using the system can automatically adjust the brightness adjustment system. We know the day and night, brightness changes in different time and place environment greatly, if the brightness of LED advertising machine display greater than sixty percent brightness, we will obviously feel eye discomfort, that is caused by light pollution on people. Through the outdoor brightness acquisition system, the environment brightness is collected at any time, and the display control system is automatically converted to the ambient broadcast brightness through the software of the receiving system.

2, multi-level gray correction technology. Ordinary LED advertising machine display system using 8bit color display level, so in some low gray and color over the color is stiff, will also cause color light not adapt. The new LED large screen control system uses 14bit color display level, greatly improving the color on the excessive hardness, so that people feel soft when watching, to avoid people's discomfort to light.
