In recent years, with the country‘s emphasis on "energy saving, emission reduction, low-carbon and environmental protection", as one of the important components of manufacturing industry, "energy saving" of LED display industry is also a topic that LED display manufacturers have been concerned about.

China‘s LED display industry has been deeply cultivated and developed for decades. It has experienced the glorious period of "in the prime of life" and the downturn period of "bloody storm".Chinese enterprises have also made great achievements in LED display quality, technology and innovation.Now, the major LED screen companies have launched energy-saving screen, to respond to the national policy of energy conservation, reduce energy consumption.However, as far as the current situation is concerned, China‘s LED industry is facing the situation of coexistence of risks and opportunities.Increasingly fierce competition, declining profits and frequent overcapacity have become common features of LED display industry.LED display companies only through the development of "green manufacturing" mode of production to make products in manufacturing design, the use of recycling and disassembly and reuse in the process of the whole life cycle, improve resource utilization rate of energy is high, reduce the pollution to the environment, has been reduced and the social harm to human body health, and coordination of the economic benefit and social benefit of enterprise itself.

At present, many LED display enterprises in the industry have been involved in the research and development and production process of energy saving and emission reduction.At present, some energy-saving LED screens in the market, mainly through the improvement of power supply to improve the energy-saving effect, attracted the attention of many consumers, and gave quite high expectations.

This way of starting from the power supply, one is in the existing LED display directly using half bridge or full bridge high efficiency switching power supply, coupled with synchronous rectification energy saving effect is significant;The second is to reduce the power supply voltage as far as possible under the state of constant current driving IC, and achieve better energy saving effect by separating the red, green and blue cores for power supply.Of course, the application cost of this kind of non-standard voltage power supply and new technology is bound to rise.From the IC screen drive, energy saving is not obvious, reducing the drive constant current differential pressure will also bring new problems including cost.Part of the IC enterprise publicity drive energy-saving design, is nothing more than a sales strategy.

So, in addition to saving energy from LED display power supply, what other ways can we better realize LED display energy saving?

Compared with other traditional advertising methods, LED display itself has the "halo" of energy saving and environmental protection -- LED display has the brightness self-regulation function, so another aspect is to achieve the purpose of energy saving by adjusting the brightness of LED display.

LED display itself USES luminous materials is energy-saving products.However, because the area of outdoor display screen is generally larger, higher brightness, so the consumption of electricity is larger.However, the brightness of outdoor LED screen needs to be reduced at night due to great changes in the ambient brightness during the day and at night, so the self-adjustment function of brightness is very necessary.

However, given that LED display material itself is a natural property of energy-saving, but in the actual application process, the display area usually belongs to a larger occasion, a long time running and high brightness playback, power consumption naturally cannot be underestimated.In the application of outdoor advertising, advertisers not only bear the cost of LED display itself, but also increase the electricity cost geometrically with the use time of equipment.Therefore, only from the technical level of improvement in order to solve the root cause of greater energy saving products.

Reduce energy consumption there is a common method is to use screen brightness automatic adjustment technology, according to the screen outside brightness, to automatically adjust the display brightness, so that not only can save energy, but also the audience to bring a comfortable feeling.Secondly, it is reasonable to arrange the switch screen time, can also greatly reduce energy waste.
