How to improve the use effect of LED dome screen
1.Brightness problem and solution about LED display screen
At present, the brightness of various indoor LED displays in the market can reach more than 1000Nits, but in practical applications, some scenes do not need such a high brightness, so what to do?
The right and common way are to set the factory default brightness of the LED display before it leaves the factory. This brightness value determines the maximum brightness that the LED display can achieve when it is used. Of course, the factory default brightness is not set arbitrarily, but according to the specific application environment.
For these scenes such as shopping malls, exhibitions, etc, the factory default brightness may need to be set up to 800-1000Nits.
For conference rooms, museums, theme parks, things like that, maybe 500-600 Nits is enough.
But for darker scenes such as cinema and radio, only 300nits is required, or even lower.
Moreover, the factory default brightness can be adjusted later according to the situation, especially for LED screen rental, which needs to be often installed in different activity places, and engineers will adjust the brightness according to the situation of the scene. Therefore, there is no need to worry about the discomfort that will be caused by the brightness of the LED screen.
In addition, reducing brightness has the following benefits:
- Reducing power consumption and saving energy.
- Ensure the consistency of color on the screen.
- Slowing down the decay rate of LED lamps and prolonging the service life.
2.Acoustic transmission problem and solutions
As early as 2018, the Galaxyavi team noticed problems with sound penetration and echo in the LED dome screen, and put a lot of effort into solving the problem.
Using perforated LED modules to solve the problem of sound transmission is an ideal way, but the electronic design and production process required to achieve this solution is very difficult, and there are few factories in the market to achieve this process perfectly.
Galaxyavi has tested a variety of sound-permeable LED dome screen samples that pitch range from P2.5 to P5.0mm over the past two years. Among them, LED with P4.0 to P5.0 pitch is currently the most suitable scheme for flying cinema, which covers 20m diameter flying cinema from 8K resolution to 6K resolution specifications. Through testing, the sound penetration of the P4.0 perforated module has reached up to 90%, which is a perfect solution for the problem.
After testing, it can be concluded that basically, the dome LED screen above the P4.0 pitch will not have the problem of sound penetration. In addition, in other resolution dome screens we tested, such as the P2.5 pitch sound permeation dome LED display, due to the number of sound permeation holes being reduced and the hole getting small, there will be some influence on sound permeation. But the increase of power for the corresponding frequency of sound waves can improve the situation.
As a professional LED display manufacturer, Galaxy av has created countless brilliant moments in its more than ten years of history, leading the industry with high-end LED display technology. We can provide you with better-LED display products and customized LED display solutions. Come on, Let’s have a first chat!
