China's LED display industry has been deeply cultivated and developed for decades. It has experienced a glorious period of "brilliance and prosperity", and has also endured a downturn of "rebellious storm". Chinese companies have also achieved significant results in the quality, technology, and innovation of LED displays. But judging from the current status quo, China's LED industry is facing a situation where both dangers and opportunities coexist. Increasing competition, declining profits, and frequent overcapacity have become common developments in the LED display industry. Only through the development of "green manufacturing" production methods, LED display companies can increase the utilization of resources and energy and reduce environmental pollution during the entire life cycle process of manufacturing design, use, recycling, dismantling and reuse. Harm to human health and society, and coordinate and optimize the economic and social benefits of the enterprise itself.

"Energy saving and emission reduction" means saving energy and reducing energy consumption. As an important part of the manufacturing industry, the "energy saving" of the LED display industry is also a topic that LED display manufacturers have been paying attention to.

At present, many LED display companies in the industry have stepped into the R&D and production process of energy saving and emission reduction. At present, some energy-saving LED display screens on the market mainly improve the energy-saving effect by improving the power supply, which has attracted the attention of many consumers and has given quite high expectations.

This way of starting from the power supply, one is to directly use the half-bridge or full-bridge high-efficiency switching power supply on the existing LED display screen, and the synchronous rectification has significant energy-saving effects; the other is the constant current state of the drive IC Reduce the power supply voltage as much as possible, and achieve better energy-saving effects by separately supplying power for the red, green and blue dies. Of course, the application cost of this non-standard voltage power supply and new technology will inevitably rise. From the point of view of the screen driver IC, energy saving is not obvious, and reducing the drive constant current pressure difference will also bring new problems including cost. Some IC companies propagandize and drive energy-saving design, nothing more than a sales strategy.

So, in addition to energy saving from the LED display power supply, what other methods can better realize the energy saving of the LED display?

Compared with other traditional advertising methods, the LED display has its own energy-saving and environmentally friendly "halo"-the LED display has the function of self-adjustment of brightness. Therefore, another aspect is to achieve the purpose of 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, due to the large area and high brightness of outdoor display screens, the power consumption is still large. However, for outdoor LED displays, 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-adjustment function is very necessary.

However, given that the luminescent material of the LED display itself is an energy-saving natural attribute, in the actual application process, the display area is usually a large occasion, long-term operation and high-brightness playback, naturally the power consumption should not be underestimated . In outdoor advertising applications, in addition to the costs associated with the LED display itself, the advertising owners will also increase the electricity bill geometrically with the use of the equipment. Therefore, only the improvement of technology can solve the problem of greater energy saving of products from the root cause. (Source: China Security Exhibition Network)
