Is the brightness of LED display really the higher the better?
As we all know, led, as a new light-emitting technology, is based on light-emitting diodes. The characteristics of low energy consumption and high brightness are inherent. Therefore, LED displays are becoming more and more popular. Moreover, when introducing LED screen products to users, many businesses often take low energy consumption and high brightness as the killer mace, creating a perception that the higher the brightness the better, the more value-added for users. Is this really the case? In order to achieve a good energy-saving goal, in fact, our excessive pursuit of high brightness is contrary to the energy-saving goal. So what is the potential relationship between high brightness and high energy saving?
Generally, the brightness range of indoor LED display screens is recommended to be about 800-1200cd / m2, which is not recommended to be exceeded. The brightness range of the outdoor LED display screen is about 5000-6000cd / m2, which should not be too bright. The brightness of the LED display screen is not the higher the better. There should be a limit. For example, the maximum brightness of an outdoor LED display screen is 6000cd / m2, but you have to adjust the brightness to 7000CD / m2, which is nothing more than increasing the driving current of the LED lamp. However, the physical characteristics of LED lamps will be inevitably damaged. High brightness LED lamps must be accompanied by high attenuation and low stability. High attenuation is not only not conducive to the long-term use requirements of the LED display screens, but also a congenital defect of the excessive pursuit of high brightness, which will damage the service life and picture effect of LED display screen all the time and multiplier effect. The brightness attenuation speed will be doubled so that the attenuation speed in the later stage will be accelerated several times to become a high attenuation display screen. Moreover, it exists in the vicious circle of brightness attenuation, which can not meet the requirements of 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.
The last factor to consider is cost. Simply pursuing higher brightness is bound to increase the overall cost of the project. At the same time, it means that users are likely to pay for the performance part exceeding their use needs, resulting in waste. Therefore, in the purchase of an LED display screen, there is no need to listen to too many misunderstandings about the higher the brightness, the better the screen. The most important thing is to understand that blindly pursuing brightness is meaningless, and even causes the loss of image quality, service life, and cost.
