How to make full-color LED display more energy-saving and environmental protection

Green environmental protection has become a major theme of our times , Society is progressing , But environmental pollution is also expanding , So human beings must protect our homeland . Nowadays, all walks of life are advocating the manufacturing of green products , that LED How can enterprises develop and design products that will not produce light pollution and waste electric energy LED display , It has become an important product performance that manufacturers must solve .

 

LED The display screen has been widely used in every corner of the city , Become a unique symbol to enhance the image of the city . However , While beautifying the image of the city , The strong light on the screen also has a certain negative impact on the nightlife of urban residents . although LED Industry is a “ Luminescence ” industry , display “ Luminescence ” It's understandable , But judging from the urban environmental pollution index , It has become a new type of pollution “ Light pollution ”. So as an enterprise , Pay attention to “ Light pollution ” problem , Control the setting of brightness .

 

The first 1 Kind of ： The control method is to adopt an adjustment system that can automatically adjust the brightness .

 

According to the day and night situation , The brightness of the display changes slightly , It will have a great impact in different places and time periods . If LED The brightness of the display screen is greater than that of the environment 50%, We will obviously feel eye discomfort , Can cause “ Light pollution ”.

 

Then we can collect the ambient brightness at any time through the outdoor brightness acquisition system , By receiving the system data and using the display control system, the screen is automatically converted into the brightness suitable for the environment through software .

 

The first 2 Kind of ： Control method ： Multilevel gray correction technology .

 

ordinary LED The display system adopts 18 Bit color display level , So in some grayscale low 、 Where there is excess color , The color will be very stiff , Cause inappropriate colored light . new LED The large screen control system adopts 14 Bit color display level , Greatly improve the excessive hardness of color , It makes people feel soft when watching , Avoid people's discomfort with light .

 

In terms of power consumption ,LED Although the luminous materials used in the display screen save energy , But some need to be used in occasions with large display area . If used for a long time , The overall power consumption is still relatively large , Because the required brightness will be higher . Under the influence of these comprehensive factors , The power consumption of the display screen is quite amazing , Therefore, the electricity charge borne by all advertising owners will increase exponentially .

therefore ,

LED Display manufacturer

We can save energy through the following five points ：

 

(1) Adopt high luminous efficiency LED , Light emitting chips do not cut corners ;

 

(2) Adopt high-efficiency switching power supply , The power conversion efficiency is greatly improved ;

 

(3) Excellent screen cooling design , Reduce fan power consumption ;(4) Design a scientific overall circuit scheme , Reduce internal circuit power consumption ;

 

(5) According to the change of the external environment , Automatically adjust the brightness of the outdoor display , So as to achieve the effect of energy conservation and emission reduction
