How to make LED display more energy-saving and environmentally friendly?
1. using an adjustment system that can automatically adjust the brightness.
Depending on the day and night, in different locations and time periods, a slight change in the brightness of the display will have a great effect. If the playback brightness of the LED display is greater than 50% of the ambient brightness, we will obviously feel discomfort in the eyes, which will cause “light pollution”.
Then we can collect the ambient brightness at any time through the outdoor brightness acquisition system, and use the display control system to broadcast the picture by receiving the system data and automatically converting it into the brightness suitable for the environment through the software.
2. multi-level grayscale correction technology.
The ordinary LED display system adopts 18bit color display level, so in some low grayscale and excessive color, the color will be displayed very bluntly, so it will cause the incompatibility of colored light. The new LED large-screen control system adopts a 14-bit color display level, which greatly improves the hardness of the color in excess, so that people feel soft colors when watching, and avoid people’s discomfort with light.
In terms of power consumption, although the luminescent materials used in the LED display itself are energy-saving, some of them need to be used in occasions with a large display area. Due to long-term use, the overall power consumption is still relatively large, because of the required brightness. Under the action of these comprehensive factors, the power consumption of the display screen is quite amazing, so all the electricity bills borne by the advertising owners will also increase geometrically. Therefore, enterprises can save energy through the following 5 points:
1. By using high-efficiency LEDs, the light-emitting chip does not cut corners;
2. Adopt high-efficiency switching power supply, greatly improve the power conversion efficiency;
3. Excellent screen heat dissipation design to reduce fan power consumption;
4. Design a scientific overall circuit scheme to reduce the power consumption of internal circuits;
5. According to the changes of the external environment, the brightness of the outdoor display screen can be automatically adjusted, so as to achieve the effect of energy saving and emission reduction;
