Due to the different ambient brightness, the screen brightness requirements will also vary. The following is a detailed introduction to the screen brightness requirements in different environments:
Indoor environment
Basic requirements:
* Generally speaking, the screen brightness of the indoor environment is required to be above 800cd/m² to ensure that the content can be clearly displayed under normal indoor lighting conditions.
Considerations:
* Eye protection: Too high screen brightness may cause damage to the eyes, while too low brightness may cause visual fatigue. Therefore, when choosing screen brightness, it is necessary to comprehensively consider eye protection and display effects.
* Energy consumption: Appropriate screen brightness also helps save energy and reduce power consumption.
Semi-indoor environment (such as large floor-to-ceiling windows, large display windows, etc.)
Brightness requirements:
* For this type of environment between indoor and outdoor, the screen brightness should be selected at around 2500-4000cd/m². The brightness of this type of environment is higher than that of indoor but lower than that of outdoor, so a moderate brightness range is required to ensure the normal display effect of the LED transparent screen.
Outdoor environment
Brightness requirements:
* Due to long-term exposure to sunlight in outdoor environments, the screen needs higher brightness to ensure clear visibility of the content.
Generally speaking, the screen brightness requirement for outdoor environments is around 4500-5500cd/m². However, this range is not absolute and needs to be adjusted according to the actual conditions of the outdoor environment (such as sunlight intensity, viewing distance, etc.).
* For outdoor environments facing south and north, the brightness requirement may be slightly lower due to relatively short direct sunlight time, but it still needs to be maintained at a high level to ensure the display effect.
* For outdoor environments facing north and south, due to longer direct sunlight time and greater intensity, the brightness requirement may be higher, even requiring more than 8000cd/m².
Other considerations
Changes in ambient light: When adjusting the screen brightness, it is necessary to consider changes in ambient light.
For example, in dark environments such as cloudy days or at night, the screen brightness can be appropriately reduced to reduce energy consumption and visual fatigue.
Viewing distance: Viewing distance is also an important factor affecting screen brightness requirements.
When the viewing distance is close, the screen brightness can be appropriately reduced; when the viewing distance is far, the screen brightness needs to be increased to ensure the content is clearly visible.
Screen type: Different types of screens (such as LED display, LCD display, etc.) also have different brightness performance. Therefore, when choosing the screen type and brightness requirements, it is necessary to make comprehensive considerations based on specific application scenarios and needs.
In summary, due to different ambient brightness, the screen brightness requirements will also vary.
When choosing screen brightness, it is necessary to comprehensively consider multiple factors to ensure the best viewing effect and user experience.
