?LED display industry will meet the national energy efficiency standards in China!
In recent years, “carbon peaking, carbon neutrality”, “carbon emission trading”, “pollution reduction and carbon reduction” have become hotly discussed high-frequency words, and have also become key issues for local government agencies to plan their layout.In the first quarter of 2022, a total of? 79 “dual carbon”-related policies have been issued across the China, including 18 national policies and 61 local policies. In order to meet the development needs of the times, the display screen will also be included in the scope of energy efficiency standards.
Some people are happy about this, some people are sad. Enterprises that focus on the whole machine brand are very much in favor. They believe that low-carbon energy saving is the future development trend. If the state requires the display products that meet the energy efficiency standards to be sold, it is also a market for the entire LED display industry. Purification, the pros outweigh the cons. However, LED display module companies hold the opposite attitude. The reason is very simple. LED display is a customized product. The area of each display is not uniform, and the use function and environment are also very different. How to pass the energy efficiency standard? Did the block-by-block testing begin?

However, with the development of Mini/Micro LED technology, LED direct display products have gradually entered the consumer electronics fields such as TVs, monitors, LED movie screens, LED conference all-in-one machines, mobile phones, and tablets. avoid. In the future, only display products that meet energy efficiency standards will be able to circulate in the market.At present, Chinese?LED output value ranks first in the world. According to CCID think tank, the total output value in 2022 will reach 214.84 billion yuan. LED displays can be seen everywhere. How to save energy and reduce emissions has always been a problem that screen companies attach great importance to. At present, most screen manufacturers regard their energy saving factor as an important selling point, and common cathode technology is generally used.

Common cathode technology is a power supply technology developed relative to the traditional common anode power supply method. The common cathode power supply technology can separate the red, green and blue lamp beads of the LED display, and supply power to them separately and accurately, so that each lamp bead can work under the best current and voltage, thus improving the utilization of electric energy rate, reducing power consumption. In addition, the current of the common cathode power supply mode first passes through the LED lamp bead and then to the negative electrode of the driver IC, thereby reducing the forward voltage drop and further reducing the loss of electric energy during the circulation process. In theory, the common cathode technology can make the energy saving effect of the LED display screen reach 75%, but due to other factors, the actual power consumption reduction should be in the range of 30%-75%.
How to make the customized LED display quickly pass the energy efficiency standard will be a common problem faced by the industry at present. I believe that an effective solution will be found in the future. In the long run, the integration of the whole machine is the future trend of LED display, and only standardized products can more easily pass the national energy efficiency standards.

In fact, as mentioned by the whole machine company above, if the country compulsorily introduces energy efficiency standards for display screens, it is also a good thing for LED display screens. The market will eliminate those inferior products that do not meet the standard, each enterprise will pay more attention to product quality, the reputation of LED display will be better and better, the social acceptance will be higher, the added value of products will increase accordingly, and the market cake will become more and more After the survival of the fittest, the entire industry has formed a healthy development.
