How to Make LED Display More Energy Saving and Pro-environment?

Green environmental protection has become a major theme in the modern times. Society is advancing, but environmental pollution is also constantly expanding. Therefore, human beings must protect our homes. Nowadays, all walks of life are also promoting green manufacturing products, then how LED companies can develop and design LED displays that will not produce light pollution and waste electrical energy, which has become an important product performance that manufacturers must solve.

LED display has been widely used in various corners of the city, and has become a unique symbol to enhance the image of the city, but while it beautifies the image of the city, the strong light of the LED screen also has a negative impact on urban residents' night life. Although the LED industry is a “light-forming” industry, the LED display produce “lighting” is understandable, but it has been become to a new type of pollution “light pollution” as measured by the city's environmental pollution indicators. Therefore, as a company should pay attention to the "light pollution" problem in production, we should control the setting of brightness.

The first control method: adopting an adjustment system that automatically adjusts the brightness.

On the day and night, a slight change in display brightness can have a significant effect in different locations and time periods. If the brightness of the LED display is greater than 50% of the ambient brightness, we will obviously feel the eye discomfort, which will cause "light pollution."

Then we can use the outdoor brightness acquisition system to collect the ambient brightness at any time, and use the display control system to receive the system data and automatically convert into brightness which a suitable environment by software for the broadcast.

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

The ordinary LED display system adopts 18-bit color display level, so that in some low gray scales and excessive colors, the color will be displayed very hard, so it will cause the color light to be unsuitable. The new large LED screen control system uses a 14-bit color display hierarchical, which greatly improves the excessive hardness of the color, so that people feel soft color when watching, and avoid people's discomfort with light.

In terms of power consumption, although the illuminating material used in the LED display itself is energy-saving, some applications need to be applied in a large display. Because of long-term use, the overall power consumption is still large because of the high brightness required. Under the influence of these comprehensive factors, the power consumption of the LED display screen is quite amazing, and the electricity expenses of all the advertising owners will also increase geometrically. Therefore, companies can save energy by using the following five points:

1. The high-efficiency LED can be used, and the light-emitting chip does not cut corners.

2. Adopting high-efficiency switching power supply to greatly improve power conversion efficiency.

3. Designing excellent cabinet heat dissipation to reduce fan power consumption.

4. Designing a scientific overall circuit plan to reduce the internal line power consumption.

5. According to the changes of the external environment, automatically adjust the brightness of the outdoor led display to achieve the effect of energy saving and emission reduction.
