Reduce light pollution: LED display manufacturers should master the brightness settings

LED displays have become widely used on various street corners in cities, becoming a unique icon that enhances the city's image. However, while LED displays beautify the image of the city, the strong light on the screen also has a certain negative impact on the nightlife of city residents. Although the LED industry is a "light-making" industry, it is understandable that the display screen "produces light", but from the perspective of urban environmental pollution indicators, it has become a new type of pollution - "light pollution". Therefore, LED display manufacturers should pay attention to the problem of "light pollution" and control the brightness settings during production.

1. Automatically adjust the brightness

LED display manufacturers use an adjustment system that can automatically adjust the brightness during production. Depending on the day and night, in different places and time periods, slight changes in the brightness of the LED display can make a big difference. If the playback brightness of the LED display is greater than 50% of the ambient brightness, we will feel uncomfortable for our eyes, which will cause "light pollution".

We can collect the ambient brightness at any time through the outdoor brightness collection system, use the LED display control system to receive the system data, and automatically convert it into the brightness suitable for the environment through the software for broadcasting.

 

2. Multi-level grayscale correction technology

The ordinary LED display system adopts an 18-bit color display level, so that in some low gray and excessive color situations, the color will appear very stiff, so it will cause the color light to be uncomfortable. The new LED large screen control system adopts a 14-bit color display level, which greatly improves the excessive hardness of the color, so that people feel that the color is soft when watching, and avoids people's discomfort with light.

In terms of power consumption, although the luminous materials used by the LED display itself are energy-saving, if used in some large areas, Due to long-term use, the overall power consumption is still relatively large. Under the influence of these comprehensive factors, the power consumption of LED display is very amazing, so LED display manufacturers can save energy through the following points:

1. Adopt high-efficiency LEDs, and the light-emitting chip does not cut corners;

2. Use high-efficiency switching power supply to improve power conversion efficiency;

3. Good screen heat dissipation design to reduce the power consumption of the fan;

4. Design a scientific overall circuit scheme to reduce the power consumption of the internal line;

5. According to the changes in the external environment, the brightness of the outdoor LED display is automatically adjusted to achieve the effect of energy saving and emission reduction.
