With the rapid development of society, all walks of life are also advocating the manufacture of green products, LED industry is no exception. LED display has been widely used in every corner of the city, has become a unique symbol to enhance the image of the city, beautify the image of the city. The LED industry should keep pace with The Times, respond to the call of the state, and promote energy-saving and environmental protection products. As we all know, the LED display may not achieve the ideal effect in terms of 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 displays be more energy efficient?

Choose the LED display made of environmentally friendly materials, after special processing technology, without glue, you can make the screen body to achieve the purpose of waterproof, dustproof and ultraviolet radiation. It is less consumable and more environmentally friendly than the products produced by the general process.

LED display driver chip using the international advanced LED display dedicated chip system, the system in the field of full color LED display alone manufacturers. Combined with its chip characteristics, constant current noise reduction technology is formed to ensure that the influence of other noise source factors such as power supply on LED electronic display is reduced to a very low level. Some driver ics can also save energy from the original 5V voltage to 4.2V to achieve energy-saving functions.

Depending on the day and night, in different location environments and time periods, a slight change in the brightness of the display will have a great effect. If the brightness of the LED display is greater than 50% of the ambient brightness, we will obviously feel eye discomfort, which will cause "light pollution".

The ordinary LED display system uses an 18bit color display level, so that in some low gray scale and excessive color, the color will be displayed very blunt, so it will cause the color light is not suitable. The new LED large screen control system uses a 14bit color display level, which greatly improves the hardness of the color on the excessive, so that people feel the color is soft when watching, and avoid people's discomfort with light.

The realization of LED energy-saving display is mainly started from the power supply, and the half-bridge or full-bridge high-efficiency switching power supply is directly used on the existing LED display, coupled with synchronous rectification and energy-saving effect is significant. To the driver IC constant current state to minimize the power supply voltage, through the red, green and blue core separate power supply to achieve better energy saving effect.
