As we all know, led is a modern light-emitting technology that uses light-emitting diodes. The properties of low energy consumption and high brightness are inherent. Consequently, LED displays are becoming increasingly popular. Furthermore, when offering LED screen products to users, many organizations frequently emphasize low energy consumption and high brightness as the deciding factors, generating the impression that the higher the brightness, the better, and the more value-added for users. Is this indeed the case? In order to accomplish a good energy-saving aim, we must avoid excessive brightness. So, what is the possible relationship between great brightness and high energy efficiency?

In general, the recommended brightness range for indoor LED display displays is 800-1200cd/m2, which should not be surpassed. The brightness range of the outdoor LED display screen is around 5000-6000cd/m2, which is not excessively bright. The brightness of the LED display screen does not improve as it increases. There should be a limit. For example, the maximum brightness of an outdoor LED display screen is 6000cd/m2, but you must modify it to 7000cd/m2, which is simply raising the LED lamp’s driving current. However, the physical properties of LED bulbs will ultimately deteriorate. High-brightness LED bulbs must have high attenuation and low stability. High attenuation is not only unsuitable for the long-term use requirements of LED display screens, but it is also a congenital defect caused by the overzealous pursuit of high brightness, which will harm the service life and picture quality of LED display screens over time, as well as the multiplier effect. The brightness attenuation speed will be doubled, causing the attenuation speed in the following stage to accelerate multiple times, resulting in a high attenuation display screen. Furthermore, it is trapped in a vicious cycle of brightness attenuation, making it unsuitable for long-term use.

Moreover, today, the problem of light pollution in cities around the world has been very serious. Many countries have even issued laws and regulations to strictly control the brightness of outdoor lighting and display screens. LED display screen, as one of many display technologies with high brightness, has almost become the overlord of outdoor display. However, once at night, the over-bright screen will become invisible pollution. Therefore, it is more meaningful to pursue the balance between brightness and environmental protection.

Furthermore, the issue of light pollution in cities around the world has become increasingly significant. Many countries have even passed rules and regulations to restrict the brightness of outdoor lighting and display screens. LED display screens, as one of many high-brightness display technologies, have nearly supplanted traditional outdoor displays. However, at night, the overly bright screen will produce invisible pollution. As a result, it is increasingly meaningful to seek a balance between brightness and environmental preservation.
