How LED Companies Develop And Design Energy-saving And Environmentally Friendly LED Displays

Green environmental protection has become a major theme in the modern era. The society is advancing, but the environmental pollution is also constantly expanding. Therefore, human beings must protect our homes. Nowadays, all walks of life are also promoting green manufacturing. Products, how can LED companies such as powerful giants develop and design LED displays that do not produce light pollution and waste electrical energy, which has become an important product performance that manufacturers must address.

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 screen also has a certain impact on the night life of urban residents. Negative impact. Although the LED industry is a “light-forming” industry, the display “lighting” is understandable, but it has been reduced 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 method of control: an adjustment system that automatically adjusts the brightness.

Depending 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 the brightness into a suitable environment 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 LED large-screen control system uses a 14-bit color display layer, 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 area. Because of long-term use, the overall power consumption is still large because of the brightness required. It will be relatively high. Under the influence of these comprehensive factors, the power consumption of the 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. Adopt high-efficiency switching power supply to greatly improve power conversion efficiency;

3. Perform excellent screen heat dissipation design to reduce fan power consumption;

4. Design 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 display to achieve the effect of energy saving and emission reduction;

The future has come, Powerful Color has been committed to technological innovation and promote industry change. Recently, some indoor LED display screens will be the first to adopt PWM-SS dual energy-saving driver IC. The chip adopts avant-garde dynamic energy-saving technology plus 4V low-voltage power supply design to form an energy-efficient solution, and the comprehensive energy saving will be as high as 35%-50% ( According to the picture quality).
