With the rapid development of society, various industries are also advocating the manufacture of green and environmentally friendly products, The LED industry is no exception. LED display screens have been widely used in various street corners of cities, becoming a unique symbol to enhance the city's image and beautify it. The LED industry should keep up with the times, respond to the national call, and promote energy-saving and environmentally friendly products. As is well known, LED displays may not achieve ideal energy efficiency due to their high brightness, but this does not necessarily mean that they must be high energy consuming products. So how can LED displays be more energy-efficient?
01 Choose environmentally friendly materials
LED display screens made of environmentally friendly materials, processed through special processing techniques, can achieve the goal of waterproof, dustproof, and UV protection without the need for glue. Products produced by conventional processes have fewer consumables and are more environmentally friendly.
02 Constant current noise reduction technology
The LED display screen driver chip adopts an internationally advanced LED display screen specific chip system, which is the leading manufacturer in the field of full-color LED displays. Based on the characteristics of its chip, a constant current noise reduction technology has been developed to ensure that the impact of other noise sources such as power supply on LED electronic displays is reduced to an extremely low level. Some driver ICs can also save energy from the original 5V voltage to 4.2V, achieving energy-saving functions.
03 Adopting an automatic brightness adjustment system
A slight change in the brightness of the display screen can have a significant effect in different locations and time periods, depending on the day and night. If the playback brightness of the LED display screen is greater than 50% of the ambient brightness, we will clearly feel discomfort to the eyes, which will cause "light pollution".
04 Multi level grayscale correction technology
A regular LED display system uses an 18 bit color display hierarchy, which makes the colors appear stiff in some low grayscale and color transitions, resulting in discomfort with colored light. The new LED large screen control system adopts a 14 bit color display hierarchy, greatly improving the hardness of colors in transition, making people feel soft colors when watching, and avoiding discomfort with light.
05 Power supply
The implementation of LED energy-saving display screens mainly starts from the power supply. Half bridge or full bridge high-efficiency switching power supply is directly used on existing LED display screens, and synchronous rectification has a significant energy-saving effect. Minimize the power supply voltage as much as possible while driving the IC in a constant current state, and achieve better energy-saving effects by separately supplying power to each red, green, and blue chip.
