LED display has become the mainstream technology on the market. The reason why LED technology can replace the original CCFL and other technologies is mainly due to its advantages of energy saving and low cost. Although the LED itself is already very energy-efficient, people's requirements have never stopped. How to make LEDs more energy-efficient is a new topic that developers pay attention to.
At present, 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. The LED display realizes energy saving mainly from the power supply. On the existing LED display, the half-bridge or full-bridge high-efficiency switching power supply is directly used, and the synchronous rectification energy saving effect is remarkable, and the constant current of the driving IC is maintained. Try to reduce the power supply voltage as much as possible, and separate the power supply through the red, green and blue dies to achieve better energy saving effect. 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, if you want to make LED display more energy-efficient, you need to start from two aspects. The first is to renovate the circuit of the power supply, and the second is to intelligently adjust the brightness of the LED large screen to make it change with the environment. Both of these methods will increase the initial cost, but once put into operation, it will save a lot of cost for the advertising owners and users, and achieve more energy-saving purposes.
