In this era of energy-saving calls, the concept of energy-saving LED display, it is also the most eye-catching highlight of consumers, but also the reason for the growth of the fire in recent years. LED display of further energy saving has undeniably become the technical hotspot of this industry chase. Many companies in this point to improve in all aspects, to further improve the effect of energy saving, but to achieve a greater sense of energy saving, there is still a long way to go, which requires the joint efforts of the whole industry.
In recent years, there are few energy-saving LED displays on the market, through the improvement of the power supply for the LED display energy-saving effect to play a major upgrade, attracting the attention of many consumers and give a fairly high expectation, many LED display manufacturers jumped to try.
On the basis of the current technology, energy-saving LED display energy-saving effect in the end how to achieve it? LED display to achieve energy saving is mainly from the power supply.
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. In the state of constant current to minimize the power supply voltage, through the red, green and blue tube cores separate power supply to achieve a better energy-saving effect. Of course, this non-standard voltage power supply and the application of new technology costs are bound to rise. From the screen driver IC, energy saving is not obvious, reduce the drive constant current differential voltage will also bring new problems, including cost. Some IC companies to promote the drive energy-saving design, but only for the sales strategy.
How to make the LED display to achieve further energy saving?
LED display compared to other traditional advertising methods, itself comes with energy saving and environmental protection "aura". In addition to energy saving from the LED display power supply, there are those ways to better achieve energy saving LED display. LED display with brightness self-regulation function. Another aspect is through the LED display brightness adjustment to achieve the purpose of energy saving. LED display itself using light-emitting materials is energy-saving products. However, because the outdoor display area is generally larger and brighter, so the power consumption is still larger. But the outdoor LED display, due to the day and night the surrounding environment brightness has changed greatly, LED display brightness at night will need to be reduced, so the brightness self-regulation function is very necessary.
Note: But the brightness self-regulation requires some technical support.
Advertising owners prefer LED display with good energy-saving effect. the most direct beneficiary of LED energy-saving display should be the advertising owners of outdoor advertising. As installed in the outdoor LED advertising screen, generally need to run for a long time, and the area is generally relatively large, in addition to the brightness required will be relatively high, in the role of these combined factors, LED display power consumption is quite amazing.
If the LED display can be more energy efficient to achieve better energy-saving effect, then for these advertising owners, is also undoubtedly a very good news. So in the choice they will also be more preferred energy-saving display. Although there may be a slightly larger investment in the early stage, but in the subsequent operation, the savings in electricity costs, and operation and maintenance costs, will prove that their choice is correct. The choice of advertising owners will play a good role in guiding the development and production of LED display.
