Green environmental protection has become a major theme of today's era. Society is progressing, but environmental pollution is also expanding. Therefore, human beings must protect our homeland. Nowadays, all walks of life are also advocating the manufacture of green and environmentally friendly products. Products, how can LED display companies develop and design LED displays that do not produce light pollution and waste electricity energy? This has become an important product performance that manufacturers must solve. Next, Liancheng sent the editor to take everyone to take a look!

It has been widely used in every street corner of the city and has become a unique symbol to enhance the image of the city. However, while it beautifies the image of the city, the strong light of 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 "light production" of the display screen is understandable, but measured from the city's environmental pollution indicators, it has become a new type of pollution "light pollution". Therefore, as an enterprise, we should pay attention to the problem of "light pollution" in production and control the setting of brightness.

The first control method: adopt an adjustment system that can automatically adjust the brightness.

According to day and night, under different location environments 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 eye discomfort, 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 screen by receiving system data and automatically converting it into a brightness suitable for the environment through software.

The second control method: multi-level gray scale correction technology.

Ordinary LED display system adopts 18bit color display level, so that in some low grayscale and excessive color, the color will be displayed very stiff, so it will cause the discomfort of colored light. The new LED large screen control system adopts 14bit color display level, which greatly improves the hardness of the color transition, making people feel the color is soft when watching, and avoiding people's uncomfortable feeling to the light.

In terms of power consumption, although the luminescent materials used by the LED display itself are energy-saving, some of them need to be applied to occasions with a large display area. If they are used for a long time, the overall power consumption is still relatively large because of the brightness required. Under the effect of these comprehensive factors, the power consumption of the display screen is quite amazing, so the electricity bill borne by the advertising owners will also increase geometrically. Therefore, Liancheng suggested that LED display manufacturers and enterprises can save energy through the following 5 points:

(1) By using high-efficiency LEDs, the light-emitting chips do not cut corners;

(2) High-efficiency switching power supply is used to greatly improve power conversion efficiency;

(3) Carry out excellent screen heat dissipation design to reduce fan power consumption;

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

(5) According to changes in the external environment, the brightness of the outdoor display screen can be automatically adjusted to achieve the effect of energy saving and emission reduction.

The above is the relevant knowledge on how to make LED displays more energy-saving and environmentally friendly that Liancheng sent to you. I hope it will be helpful to you.
