At present, the changes in the Internet of Things have dazzled us. On the morning of June 4, at the Summit Forum on the Prosperity and Change of the Internet of Things in the Age of Shared Economy, Guo Yuansheng, chief engineer of the Electronic Device Industry Development Research Center of the Ministry of Industry and Information Technology, believes that Smart cities and energy conservation and emission reduction will be the two main lines of the development of the Internet of Things. Smart cities are steadily advancing under the coordination of national and regional departments. Energy conservation has always been the focus of attention. How can LED displays be more energy efficient?
It is understood that many companies have made various improvements on how to make LED displays more energy-efficient, but if you want to achieve greater energy savings, you still have to go a long way and need the joint efforts of the entire industry. . First of all, we know that LED display energy saving is mainly from the power supply, directly using half-bridge or full-bridge high-efficiency switching power supply on the existing LED display, plus the synchronous rectification energy saving effect is significant, driving IC constant In the state of the flow, the power supply voltage is reduced as much as possible, and the power is separately supplied by the red, green and blue dies to achieve better energy saving effects. Although the manufacturing cost will increase, it is a good idea to achieve energy saving by improving the power supply.
In addition to energy saving from the LED display power supply, energy saving can also be achieved by adjusting the brightness of the LED display. We know that although the luminescent materials used in the LED display itself are energy-saving products, because the outdoor display screen has a large area and a high brightness, the power consumption is relatively large. Because the brightness of the outdoor LED display in the surrounding environment during daytime and nighttime is huge, as the outdoor LED display, the brightness of the night should be adjusted accordingly. Although the self-reduction of brightness requires certain technical support, However, in order to achieve energy saving, the function of self-adjustment of brightness is still very necessary. An LED display with good energy-saving effect is very beneficial to the advertising owners of outdoor advertising.
In summary, we can know that to achieve more energy-saving LED display, it can be achieved from the improvement of power supply and by adjusting the brightness of LED display. The LED display achieves energy saving, which not only conforms to the main line of development of the Internet of Things era, but also benefits a lot for its advertising owners, and the choice of advertising owners has greatly promoted the development of LED display. Therefore, to achieve more energy-saving LED display, it should be the focus of attention of LED companies.
