The further energy saving of LED displays has undoubtedly become a technological hotspot pursued by this industry. Many companies have made improvements in various aspects at this point to further improve energy-saving effects. However, there is still a long way to go to achieve energy-saving in a greater sense, which requires the joint efforts of the entire industry.
I found that a few energy-saving LED displays have appeared on the market recently. The improvement of the power supply has greatly improved the energy-saving effect of LED displays, attracting the attention of many consumers and giving them high expectations. Many LED display manufacturers are eager to try it.
Based on the current technology, how is the energy-saving effect of energy-saving LED display screen realized?
The energy saving of LED display screen mainly starts from the power supply:
Directly using a half-bridge or full-bridge high-efficiency switching power supply on the existing LED display screen, coupled with synchronous rectification, has a significant energy-saving effect.
Reduce the power supply voltage as much as possible under the constant current state of the driver IC, and achieve better energy-saving effects by separately supplying power to the red, green, and blue dies.
Of course, the application cost of this non-standard voltage power supply and new technology will inevitably increase. From the perspective of the screen driver IC, the energy saving is not obvious. Reducing the constant current voltage difference of the driver will also bring new problems including cost. Some IC companies' promotion of energy-saving design is nothing more than a sales strategy.
How to further save energy on LED displays?
Compared with other traditional advertising methods, LED display screens have their own "halo" of energy conservation and environmental protection. In addition to saving energy from the power supply of LED displays, there are other ways to better achieve energy saving in LED displays.
The LED display screen has a brightness self-adjusting function. Another aspect is to achieve energy saving by adjusting the brightness of the LED display.
The luminescent materials used in the LED display itself are energy-saving products. However, since outdoor display screens generally have larger areas and higher brightness, they still consume a lot of power. However, for outdoor LED displays, due to the great changes in ambient brightness during the day and night, the brightness of the LED display needs to be reduced at night, so the brightness self-adjustment function is very necessary.
Note: However, self-adjustment of brightness requires certain technical support.
Advertising owners prefer LED displays with good energy-saving effects. The most direct beneficiary of LED energy-saving displays should be the advertising owners of outdoor advertising.
Because outdoor LED advertising screens are installed, they generally require long-term operation, and the area is generally relatively large. In addition, the required brightness will be relatively high. Under the influence of these comprehensive factors, the power consumption of LED display screens is quite alarming.
If LED displays can save more power and achieve better energy-saving effects, it will undoubtedly be very good news for these advertising owners. Therefore, they will also prefer energy-saving displays when choosing.
Although there may be a slightly larger investment in the early stage, the savings in electricity bills and operation and maintenance costs in subsequent operations will prove that their choice is correct. The choice of advertising owners will play a good guiding role in the research and development and production of LED displays.
