LED display screens have been widely used in various street corners of cities, becoming a unique symbol to enhance the city's image. However, while LED displays beautify the city's image, the strong light on the screen also has a certain negative impact on the nightlife of urban residents. Although the LED industry is a "light making" industry, and the "light production" of display screens is understandable, from the perspective of urban environmental pollution indicators, it has become a new type of pollution - "light pollution". Therefore, LED display screen manufacturers should pay attention to the issue of "light pollution" and control the brightness setting during production.
1、 Automatically adjust brightness
LED display screen manufacturers use an automatic brightness adjustment system during production. According to day and night, slight changes in the brightness of LED displays can have a significant impact at different locations and time periods. If the playback brightness of the LED display screen is greater than 50% of the ambient brightness, we will feel uncomfortable in the eyes, which will cause "light pollution".
We can collect environmental brightness at any time through the outdoor brightness collection system, use LED display screens to control the system to receive system data, and automatically convert it into brightness suitable for the environment through software for broadcasting images.

2、 Multi level grayscale correction technology
A regular LED display system uses an 18 bit color display hierarchy, which can make the color appear stiff in some low grayscale and excessive color situations, resulting in discomfort with colored light. The new LED large screen control system adopts a 14 bit color display hierarchy, greatly improving the hardness of colors in transition, making people feel soft colors when watching, and avoiding discomfort to light.
In terms of power consumption, although the LED display screen itself uses energy-saving luminescent materials, if used in certain larger areas. Due to long-term use, the overall power consumption is still relatively high. Under the influence of these comprehensive factors, the power consumption of LED displays is astonishing, so LED display manufacturers can save energy by:
1. Adopting high luminous efficiency LED, the luminous chip does not cut corners;
2. Adopting high-efficiency switching power supply to improve power conversion efficiency;
3. A good screen cooling design reduces the power consumption of the fan;
4. Design a scientific overall circuit scheme to reduce internal circuit power consumption;
5. Automatically adjust the brightness of outdoor LED display screens according to changes in the external environment, achieving energy-saving and emission reduction effects.
