For LED transparent screens in a north-facing environment, the choice of brightness needs to consider multiple factors, including environmental factors, viewing distance, viewing angle, and the purpose of the display.
Generally speaking, outdoor environments facing north and south usually have strong natural light, so LED transparent screens require higher brightness to ensure clear display in sunlight.
According to information from multiple sources, the brightness requirement of LED transparent screens outdoors (facing north and south) is usually greater than 8000CD/m². This brightness range ensures that the content of the display can still be clearly seen under strong sunlight. However, the specific brightness selection needs to be adjusted according to the following factors:
1. Environmental factors: In addition to the intensity of natural light, the lighting conditions of the surrounding environment need to be considered, such as whether there are tall buildings blocking it, whether there are other light sources interfering, etc.
2. Viewing distance: The farther the viewing distance, the lower the required brightness can be; otherwise, a higher brightness is required.
3. Viewing angle: The brightness of the LED transparent screen may vary at different viewing angles, so it is necessary to ensure that the brightness is sufficient at the main viewing angle.
4. Display screen usage: Different uses have different requirements for brightness. For example, a display screen used for advertising may require higher brightness to attract attention; while a display screen used for information display can adjust the brightness according to actual needs.
In summary, for a north-facing LED transparent screen, the brightness should be greater than 8000CD/m², but the specific value needs to be adjusted according to actual conditions. In actual applications, it is recommended to determine the optimal brightness setting through on-site testing and adjustment to ensure that the display screen can achieve the best display effect under different lighting conditions.
In addition, it should be noted that excessive brightness may increase energy consumption and heat dissipation requirements, and may also cause discomfort to the viewer's eyes.
Therefore, while pursuing high brightness, it is also necessary to pay attention to the energy efficiency and viewing comfort of the display screen.
