With the rapid development of society, "energy saving" has become one of the topics that people pay more and more attention to, and the LED industry is no exception. The survey found that led energy-saving products are widely welcomed by the public, such as LED energy-saving lamps, and LED displays belonging to the LED industry should also keep pace with the times, respond to the national call and promote energy-saving and environmental protection products. As we all know, LED display may not achieve the ideal effect in energy saving because of its high brightness, but this does not mean that it must be a high energy consumption product. So how can led display achieve energy saving? I'll introduce several tips for energy saving of LED display screen in detail. I hope they can be adopted.
1. The LED display screen made of environmental protection materials can achieve the purpose of waterproof, dustproof and ultraviolet radiation without glue filling after special processing technology. It has less consumables than the products produced by general process and is more environmentally friendly.2. 39mm extremely thin fuselage, 40% less in thickness than conventional small spacing products, with screen on the wall and screen wall in one.3. The brightness adjustment device is designed. The brightness of the application occasion is different under different weather conditions. In order to make the LED display screen achieve the best display effect, which is neither bright nor dark, the LED display screen is specially designed with a brightness 256 level adjustment device and the function of automatically adjusting the brightness according to the surrounding environment, It can ensure that the LED display screen can present a good display effect for the audience under various external brightness environments.
4. Constant current noise reduction technology, the LED display driver chip adopts the international advanced LED display special chip system, which is a leading manufacturer in the field of full-color LED display. Combined with the characteristics of the chip, the constant current noise reduction technology is studied and formed to ensure that the influence of other noise source factors such as power supply on LED electronic display screen is reduced to a very low level. Some drive ICs can also save the original 5V voltage to 4.2V to achieve the function of energy saving.5. The strong convection heat removal system makes the heat dissipation system stable. The LED display screen will release more heat after working for a long time. If the heat is not released in time, it will cause a certain degree of damage to the screen body and affect the normal use of the screen. In order to ensure the normal operation of the display screen in a stable environment, it is necessary to strengthen the heat dissipation system of the LED display screen.Through research, Honglu manufacturers have developed a heat convection channel system, which makes use of the heat conduction effect of aluminum to make the heat dissipation system of LED display more stable.
6. Power supply, the realization of LED energy-saving display screen mainly starts from the power supply. The existing LED display screen directly adopts half bridge or full bridge high-efficiency switching power supply, coupled with synchronous rectification, with remarkable energy-saving effect. Reduce the power supply voltage as much as possible under the condition of constant current to the driving IC, and achieve better energy-saving effect by supplying power separately through each tube core of red, green and blue.If the selection of LED display screen can start from five aspects: material selection, brightness adjustment, noise reduction treatment, heat dissipation improvement and power supply, then led display screen can also make its own efforts for energy conservation and environmental protection.fqj
