Energy Conservation In The LED Display Industry

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

At present, many LED screen companies in the industry have been involved in the R & and production process of energy conservation and emission reduction. At present, some energy-saving LED screens in the market mainly improve the energy-saving effect through the improvement of power supply, attracting the attention of many consumers and giving them high expectations.

LED display screens have significant advantages in energy saving compared to other display technologies, but there are also some challenges.

Advantages:

• Low energy consumption: The energy consumption of LED displays is much lower compared to traditional display technologies. They save up to 75% of energy compared to traditional incandescent bulbs and 50% of energy compared to fluorescent bulbs.

• This enables LED displays to significantly save costs in application scenarios that require long-term operation, such as retail stores or digital billboards.

• Long lifespan: LED displays have a very long lifespan, reaching 100000 hours or more, which is much longer than other display technologies. This means that fewer resources are used in the manufacturing, transportation, and replacement of display devices, thereby reducing the overall environmental impact.

• Environmental Protection: LED displays do not contain harmful substances such as mercury or lead, and are completely recyclable, which helps promote sustainability efforts.

Challenge:

• Initial cost: Although LED displays have lower operating costs, their initial installation cost may be higher than other display technologies.

• Heat dissipation issue: High brightness LED displays may generate a significant amount of heat during prolonged operation, which may require an additional heat dissipation system to maintain the performance and lifespan of the display.

• Technological maturity: In certain application areas, LED technology may still be constantly evolving to meet higher energy efficiency standards.

• Market acceptance: Due to factors such as cost and market education, the acceptance of LED displays in certain markets and applications may not be as high as traditional display technologies.

• Supply chain and standardization: The supply chain and standardization level of LED displays may not be as high as some mature display technologies, which may affect the consistency and reliability of their energy-saving performance.

Technology upgrading is the key to “energy saving” of LED display

This way starts from the power supply. First, half bridge or full bridge high-efficiency switching power supply is directly used on the existing LED display screen, and the synchronous rectification has a significant energy-saving effect; The second is to reduce the power supply voltage as much as possible under the condition of driving IC constant current, and achieve better energy-saving effect through separate power supply of red, green and blue die. Of course, the application cost of this non-standard voltage power supply and new technology is bound to rise. From the perspective of screen drive IC, energy saving is not obvious, and reducing the constant current differential pressure will bring new problems including cost. Some IC enterprises promote energy-saving design out of their sales strategy.

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

Compared with other ordinary LED screens, the VegooLED displays has its own energy-saving and environment-friendly “halo” .Therefore, another aspect is to achieve the purpose of energy saving by adjusting the brightness of the LED display.

In summary, LED displays have significant advantages in energy conservation, but there are also some challenges and shortcomings. With the continuous development of technology and the reduction of costs, it is expected that LED displays will play a greater role in the field of energy conservation.
