How to reduce the light pollution of outdoor LED display

With the advantages of high brightness and high refresh rate of LED display, Royal display has become the leader in the field of outdoor advertising screen, resulting in more and more serious pollution. Of course, the pollution of LED display is also involved. How to better avoid light pollution, Let the outdoor LED display show real advantages. At present, the following methods are obtained in combination with the industry and user feedback. After understanding, you will have a deeper understanding of the electronic display:

1. LED display area and installation position

Reasonably plan the area and location of the display screen according to the viewing distance and the viewing environment. The display must be installed with a certain inclination and a certain height. When the inclination between the display screen and the vertical is less than 45 °, it will be more in line with people's perspective and better reduce the impact of direct light and astigmatism on the surrounding environment. The display screen is installed within 10 meters from the ground, which can better reduce a significant impact of astigmatism and direct light on the environment.

2. Controls the display brightness of the LED display

We all know that the brightness of the surrounding environment will be relatively low at night. Many people will automatically reduce the brightness of the LED display screen at night through brightness adjustment technology. Therefore, we should adjust the brightness of the electronic screen at night and restore the normal brightness during the day. In this way, it will not affect the effect of the LED screen and reduce the light pollution of the LED display screen at night, It also better saves an electric energy of the display screen.

3. Reasonable display of broadcast content and materials

LED display screen is a public media, including public welfare, advertising, instructions, etc. When we choose the broadcast content, we must reach an agreement with the public requirements to avoid refusing to watch. This is also an important aspect of preventing and controlling light pollution of display screen.

Then, the light pollution of LED display screen is closely related to the displayed color. Therefore, when displaying and playing materials, we should use more high-purity colors, use more mixed colors, and try to use less low-purity and high brightness colors as the main color. The transformation between the previous video and the next video does not need to be too fast and slow, and do not use too many flashing pictures.

4. Automatic brightness adjustment system

We know that during the day and night, the brightness of the environment changes greatly at different times and places, so the brightness changes are different. If the brightness of the display screen is more than the environment, especially at night, strong light will cause people's eyes to be unfit or hurt. However, we can automatically and freely switch through the control system of automatic brightness adjustment, so that we can automatically change the display brightness according to the ambient brightness, so as to achieve the effect of outdoor LED display screen to avoid light pollution.

Based on the above, as a light source, LED display screen will inevitably have light pollution problems in the process of operation. In order to effectively prevent the harm caused by outdoor advertising LED display screen to human body, reasonable and feasible measures should be taken to eliminate the light pollution of LED display screen on the basis of comprehensive analysis of its light pollution problems, so as to provide protection for human health, It can also provide favorable help for broadening the application range of LED display.
