Precautions for the use of outdoor full-color LED display

With the continuous development of the urban construction process, outdoor LED displays are more and more used as a new carrier of advertising in the media. Outdoor LED display can indeed bring a certain improvement to the city’s image, and the advertising forms are also flexible and diverse. However, there are still some things that need to be paid attention to in the use of outdoor LED displays:

1. Structural design

Outdoor LED displays generally have a large area, so they are still very heavy. LED display installed outdoors, the home page needs to pay attention to the design of the structure. The installation structure should take into account: wind resistance, earthquake resistance, bearing and other main factors; secondly, the shape, structure and exterior decoration design of the screen should be coordinated with the attached building or environment; thirdly, it is to consider local environmental factors, such as Air humidity, air salinity content (seaside cities), etc.

2. Light pollution

In recent years, with the popularity of LED displays, the concept of “light pollution” has been proposed. So in the end is LED display considered “light pollution”? According to the current international definition of light pollution, it is usually divided into three categories: white light pollution, artificial daylight and color light pollution. At present, my country only has relevant regulations on the glass curtain wall in the white light pollution, and there is no relevant regulation on the artificial daylight and colored light pollution. However, considering that colored light pollution does cause people to feel uncomfortable, it should be classified as “light pollution”. The problem of light pollution control of the display screen has been considered when designing the display screen.​

According to the reasons for the formation, our products have adopted corresponding solutions:

1. Reasonably plan the display area and installation location

According to the viewing distance and viewing angle as well as the surrounding environment, as well as the requirements of the display content, reasonably plan the display area and location. Instead of blindly pursuing a large area and a prominent location.​

2. Selection and design of playback content

Large giant display screens are public media, including public welfare, advertising, and instruction. When we choose the content to broadcast, we must reach an agreement with the public’s requirements to avoid rejection.​

3. Multi-level grayscale correction technology improves color softness.​

LED display products use more gray levels, so that the colors look soft and the transition is natural.​

4. The brightness adjustment system that can be automatically adjusted by the system is adopted.

The brightness of the environment varies greatly at different times and places. If the brightness of the display screen is too much higher than the environment, it will cause people’s eyes to not adapt, especially the brightness difference between day and night is relatively large, causing light pollution. Our automatic brightness adjustment The system can automatically convert the broadcast brightness suitable for the environment to avoid light pollution.​

Compared with products such as neon lights and white light box advertisements, in recent years, many LED display manufacturers have done a lot of work on light pollution, and the degree of light pollution has been greatly reduced. great contribution.

3. Low carbon, energy saving

Since its appearance, the LED display has always been valued for energy saving and environmental protection. LED is synonymous with energy saving. Compared with traditional lighting products, the energy-saving advantages of LED are quite obvious and prominent. In the near future, there is a tendency to fully replace traditional lighting.​

With the enhancement of people’s awareness of environmental protection all over the world, we can hear about low carbon, energy saving and emission reduction everywhere, and we can feel people’s efforts for environmental protection: urban electric taxis; LED street lights; solar + wind energy street lights; no Fluorine refrigerators, air conditioners, etc. are the most real feelings in our lives.​

The luminescent material used in the LED display itself is an energy-saving product. However, since the area of ​​the outdoor LED display is generally large, the power consumption is still relatively large. At present, many outdoor LED display manufacturers have launched more energy-saving and low-carbon outdoor LED display products in response to the call of the World Energy Organization and the long-term development interests of the industry. A big improvement.​

Outdoor LED display, because the brightness of the surrounding environment changes greatly during the day and night, we can achieve the effect of energy saving and emission reduction by automatically adjusting the brightness of the outdoor LED display.
