how to design and design LED electronic screen that will not cause light pollution and waste of electric energy has become an important product performance that manufacturers must solve?
LED electronic display screen is widely used in the city, which has become a unique symbol to improve the image of the city. However, while beautifying the image of the city, the strong light of the screen shape has a negative impact on the night life of urban residents. LED industry as a “light manufacturing” industry, is the production of “display” light industry, but from the city’s environmental pollution indicators, has become a new type of pollution “light pollution”. Therefore, enterprises should pay attention to the problem of “light pollution” in production, and adjust the brightness setting well.
The first control method is to use an automatic brightness adjustment system.
Depending on the day and night, the environment and duration of the place, slightly changing the brightness of the display will have a great effect. If the playback brightness of LED electronic screen is greater than 50% of the ambient brightness, it may cause eye problems and “light pollution”.
Through the outdoor degree collection system, the ambient brightness can be collected at any time, and the system data can be received by the display control system, which can be automatically converted to the brightness suitable for the environment through the software.
The second control method is multi-level gray correction technology.
Conventional LED display systems use 18 bit color display levels, so the colors are stiff in some low gray and excessive colors, which may not match the color illumination. The new LED large screen control system uses 14 bit color display level, which greatly improves the excessive color hardness, brings a soft and comfortable feeling to the color while watching, and prevents people from feeling uncomfortable with the light.
In terms of power consumption, the light-emitting materials used in LED electronic screen have energy efficiency, but if the display area is large, the overall power consumption is still large. Because it needs high brightness. Under the effect of this composite factor, the power consumption of the display is quite amazing, so the electricity charge borne by the advertising owners may also increase geometrically. Therefore, LED electronic screen manufacturers can save energy through the following five aspects:
(1) The light-emitting chip uses high light-emitting LED, which can prevent the work from reducing.
(2) The use of efficient switching power supply, greatly improve the power conversion efficiency.
(3) Excellent screen cooling design, reduce fan power consumption;
