To determine whether the brightness of the LCD splicing screen meets surveillance requirements, the following aspects can be considered:
Ambient lighting conditions of the surveillance environment:
If the monitoring room has ample lighting, with direct sunlight or strong artificial illumination, it is necessary to select high-brightness splicing screens to ensure clear visibility of the display content without being washed out by ambient light. Generally, indoor environments with strong lighting require splicing screens with a brightness of 700 cd/m² or higher.
Screen mounting position and angle:
If the splicing screen is installed in a position prone to reflections or at a significant tilt angle, higher brightness may be required to counteract the effects of glare and viewing angle limitations.
Criticality of surveillance content:
For key monitoring areas or content requiring special attention, higher brightness can enhance visual prominence and better attract the attention of surveillance personnel.
Consideration of contrast ratio:
Brightness and contrast are typically interrelated. Higher brightness combined with appropriate contrast can enhance the image's sense of depth and dimensionality. When evaluating brightness, contrast ratio parameters should also be taken into account.
Practical Observation and Experience:
Under various lighting conditions, personally observe the display performance of Huabangying Technology's 55-inch 1.7mm LCD splicing screens. This includes testing during daytime, nighttime, and under different artificial lighting environments to determine whether the brightness meets operational requirements.
