In this era of high energy-saving calls, the concept of energy-saving LED display is also the highlight of its most attractive to consumers, and it is also the reason for the rapid growth in recent years.
The further energy-saving of LED display has become a hot spot for the industry to pursue. Many companies have made improvements in various aspects to further improve the effect of energy conservation, but there is still a long way to go to achieve greater energy conservation, which requires the joint efforts of the entire industry.
It has been found that there are a few energy-saving LED displays on the market recently. Through the improvement of the power supply, the energy-saving effect of the LED display has been greatly improved, attracting a lot of consumers' attention and giving a fairly high Looking forward to it, many LED display manufacturers are eager to try.
Based on the current technology, how is the energy-saving effect of energy-saving LED display realized?
LED display energy saving is mainly from the power supply:
The half-bridge or full-bridge high-efficiency switching power supply is directly used on the existing LED display, and the energy saving effect of synchronous rectification is remarkable.
In the state of driving IC constant current, the power supply voltage is reduced as much as possible, and the power is separately supplied through the red, green and blue dies to achieve better energy saving effect.
Of course, the application cost of such non-standard voltage power supplies and new technologies is bound to increase. From the perspective of the screen driver IC, the energy saving is not obvious. Reducing the driving constant current differential pressure will bring new problems including cost. Some IC companies promote driving energy-saving design, nothing more than a sales strategy.
How to make the LED display achieve further energy saving?
Compared with other traditional advertising methods, LED display itself has its own “aura†for energy saving and environmental protection. In addition to energy saving from the LED display power supply, there are ways to better achieve LED display energy saving.
The LED display has brightness self-adjustment. Another aspect is to achieve energy saving by adjusting the brightness of the LED display.
The luminescent material used in the LED display itself is an energy-saving product. However, since the area of ​​the outdoor display screen is generally large and the brightness is high, the power consumption is still large. However, the outdoor LED display, due to the great changes in the brightness of the surrounding environment during the day and night, the brightness of the LED display needs to be reduced at night, so the brightness self-regulation function is very necessary.
Note: But brightness self-adjustment requires some technical support.
Advertising owners prefer LED displays with good energy savings. The most direct beneficiary of LED energy-saving displays should be the advertising owners of outdoor advertising.
Due to the installation of outdoor LED advertising screens, it usually takes a long time to operate, and the area is generally large, and the required brightness will be relatively high. Under these comprehensive factors, the power consumption of the LED display is quite Astonishing.
If the LED display can save more power and achieve better energy saving effect, then it is undoubtedly a very good news for these advertising owners. Therefore, they will also prefer the energy-saving display in their choice.
Although it is possible to have a slightly larger investment in the early stage, in the subsequent operations, the saved electricity costs and operating and maintenance costs will prove that their choice is correct. The choice of advertising owners will play a good guiding role in the development and production of LED displays.
