How to purchase energy-saving LED display screens

Green environmental protection has become a major theme of the times. The society is making progress, but the environmental pollution is also expanding. Therefore, mankind must protect our home. Now, all walks of life are also advocating the manufacture of green and environmentally friendly products. How can LED enterprises develop and design LED displays that will not produce light pollution and waste electric energy has become an important product performance that production enterprises must solve.Panavisual, as a professional LED display screen manufacturer, provides you with the following suggestions | Rental LED screen Supplier | LED display Manufacturer


LED display screens have been widely used in various street corners of cities and have become a unique symbol to enhance the city's image. However, while beautifying the city's image, the strong light on the screen also has a certain negative impact on the night life of urban residents. Although the LED industry is a "light making" industry, and the display screen "light generating" is not to blame, it has become a new type of pollution "light pollution" measured from the urban environmental pollution indicators. Therefore, enterprises should pay attention to the problem of "light pollution" in production and control the brightness setting.


The first control method is to use an automatic brightness adjustment system.

According to the day and night, slight changes in the brightness of the display screen can have a significant effect in different locations and time periods. If the brightness of the LED display screen is 50% greater than the ambient brightness, we will obviously feel uncomfortable with our eyes, which will cause "light pollution".


So we can use the outdoor brightness collection system to collect the ambient brightness at any time, and use the display screen control system to receive system data and automatically convert it into a suitable brightness for the environment through software to broadcast the image.

The second control method is multi-level grayscale correction technology.


Ordinary LED display screen systems use an 18bit color display hierarchy, which makes the colors appear stiff in some low grayscale and color transitions, resulting in color light discomfort. The new LED large screen control system adopts a 14bit color display hierarchy, greatly improving the hardness of colors in transition, making people feel soft when watching and avoiding discomfort with light.


In terms of power consumption, although the luminescent materials used in LED display screens are energy-saving, some need to be applied in larger display areas. Due to long-term use, the overall power consumption is still relatively high because it requires higher brightness. Under these comprehensive factors, the power consumption of the display screen is quite astonishing, and the electricity bills borne by advertising owners will also show a geometric growth. Therefore, enterprises can save energy through the following 5 points:

(1) By using high luminous efficiency LEDs, the luminescent chips do not cut corners;

(2) Adopting high-efficiency switching power supply, greatly improving power conversion efficiency;

(3) Design excellent screen heat dissipation to reduce fan power consumption;

(4) Design a scientific overall circuit scheme to reduce internal circuit power consumption;

(5) Automatically adjust the brightness of outdoor display screens according to changes in the external environment, thereby achieving energy-saving and emission reduction effects.
