First, the system can automatically adjust the brightness.
According to the day and night, in different places, environments and time periods, a slight change in the brightness of the display will have a great effect. If the brightness of the LED transparent screen is 50% greater than the ambient brightness, we will obviously feel uncomfortable with our 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 receive the system data and automatically convert it into the brightness suitable for the environment to broadcast the picture.
Second, multilevel gray correction technology.
Ordinary LED display system uses 18 bit color display level, so in some low gray level and excessive color, the color will be displayed very hard, so it will cause color light not adapt. The new LED large screen control system uses 14bit color display layer, which greatly improves the excessive hardness of color, makes people feel soft color when watching, and avoids people’s uncomfortable feeling to light.
In terms of power consumption, although the luminous materials used by LED display screen are energy-saving, some of them need to be applied in the occasions with large display area. If it is used for a long time, the overall power consumption is still large, because the brightness required is relatively high. Under the effect of these comprehensive factors, the power consumption of LED flexible screen is quite amazing, so all the electricity borne by advertising owners Fees will also increase geometrically.
LED display energy saving methods have the following several?
By using high luminous efficiency LED, the light-emitting chip does not cut corners;
2. High efficiency switching power supply is adopted to greatly improve the power conversion efficiency;
The fan is designed to reduce power consumption;
4. Design a scientific overall circuit scheme to reduce the power consumption of internal lines;
