LED, a new type of light-emitting technology based on light-emitting diodes, boasts lower energy consumption and higher brightness compared to traditional light source technologies. Therefore, LED mobile video walls are widely used in various fields of daily life and production. However, many companies, when introducing LED screen products to users, often use low energy consumption and high brightness as promotional gimmicks, instilling the concept that higher brightness is always better and more valuable. But is this really the case?
1. LED screens use self-emissive technology. As a light source, LED beads inevitably experience brightness decay after a period of use. To achieve high brightness, a larger driving current is required. However, under strong current, the stability of the diode light-emitting sphere decreases, and the decay rate accelerates. In other words, simply pursuing high brightness actually comes at the cost of sacrificing the quality and lifespan of the LED screen. The investment cost may not be recovered before the LED mobile video wall can no longer provide service, resulting in resource waste.
2. Currently, light pollution in cities worldwide is a serious problem. Many countries have even introduced strict policies and regulations to control the brightness of outdoor lighting and LED mobile video walls. LED screens are currently one of the brightest display technologies, occupying a mainstream position in outdoor displays. However, at night, excessively bright screens become invisible pollution. If brightness must be reduced to meet national environmental standards, it will result in severe grayscale loss, affecting screen clarity and other aspects.
Besides these two points, the cost increase must also be considered. Higher brightness means higher overall project costs, and whether users truly need such high brightness is debatable, potentially leading to wasted performance.
Therefore, simply pursuing high brightness when choosing LED mobile video walls can be harmful to human health. Thus, higher brightness is not always better for LED mobile video walls. When purchasing LED mobile video walls, exercise your own judgment regarding advertising claims and don't blindly believe everything you hear. Consider your specific needs, comprehensively weighing the cost-effectiveness and application requirements of the LED mobile video wall, and avoid blindly pursuing high brightness.
