Is the brightness of the LED display really the higher the better?
As we all know, LED, as a new light-emitting technology, is based on light-emitting diodes, and has the characteristics of low energy consumption and high brightness. Therefore, LED displays are becoming more and more popular. Not only that, when many merchants introduce LED screen products to users, they often use “low energy consumption and high brightness” as the selling point, creating a perception for users that “the higher the brightness, the better”. Is this true? In terms of achieving a good energy-saving goal, in fact, our excessive pursuit of high brightness LED display 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 displays is recommended to be around 800-1200cd/㎡, and it is recommended not to exceed this range. The brightness range of outdoor LED displays is around 5000-6000cd/m2, which should not be too bright. The brightness of the LED display is not as high as possible. There should be a limit. For example, the maximum brightness of the outdoor LED display used is 6000cd/m2, but you have to adjust the brightness to 7000cd/m2, which is nothing more than increasing the LED lights. current. However, the physical characteristics of LED lamps will inevitably be damaged: high-brightness LED lamps must be accompanied by high attenuation and low stability characteristics. High attenuation is not only not conducive to the long-term use requirements of LED display in Zhengzhou, Henan, but also becomes a congenital defect of excessive pursuit of high brightness, and this congenital defect will damage the life of LED display and picture effect all the time and multiplier effect. It will double the speed of its brightness attenuation, resulting in several times faster attenuation in the later stage, making it a display with high attenuation. Moreover, it exists in a vicious circle of brightness attenuation, which cannot meet the requirements of long-term use at all.
Not only that, today, the light pollution problem in cities around the world has become very serious, and many countries have even issued laws and regulations to strictly control the brightness of outdoor lighting and display screens. Therefore, it is more meaningful to pursue a balance between brightness and environmental protection.
The last factor to consider is cost. Simply pursuing higher brightness will inevitably lead to an increase in the overall cost of the project. At the same time, it also means that users are likely to pay for the performance that exceeds their usage requirements, resulting in waste. Therefore, when purchasing an LED display, there is no need to listen to the misunderstanding of the merchants that the higher the brightness, the better the screen. It is the best choice to choose an LED screen with suitable brightness in combination with the actual application environment.
