LED display has been widely used in various street corners of the city, and has become a unique symbol to enhance the image of the city. However, while beautifying the image of the city, the strong light of the screen also has a negative impact on the night life of urban residents.Although the LED industry is a "light making" industry, and the display screen "light making" is not beyond reproach, it has become a new type of pollution "light pollution" as measured by the environmental pollution index of the city.Therefore, enterprises should pay attention to the problem of "light pollution" in production and control the setting of brightness.

The first control method: adopt the adjustment system which can adjust brightness automatically.Depending on the day and night, a slight change in LED display brightness can have a dramatic effect in different locations and time periods.If the display brightness of LED display is greater than 50% of the ambient brightness, we will obviously feel discomfort in the eyes, which will cause "light pollution".

We can collect the ambient brightness at any time through the outdoor brightness acquisition system, and use the LED display control system to automatically convert the system data to the ambient brightness through software to broadcast the screen.

The second control method: multistage grayscale correction technology.The common LED display system USES an 18-bit color display hierarchy, so in some places with low gray level and excessive color, the color will be very stiff, thus causing color light maladaptation.The new LED large-screen control system adopts 14bit color display layer, which greatly improves the color hardness over time, making people feel soft colors when watching and avoid people‘s discomfort to light.

In terms of power consumption, while using luminescent material is energy-saving LED display itself, but some need to be used in the display area is larger, due to the long time use, the overall power consumption still is bigger, because it need higher brightness, under the action of these comprehensive factors, the power consumption LED display is quite striking, so advertising owners all bear the electricity will be geometric growth.Therefore, enterprises can save energy through the following five points:

1. By adopting high-efficiency LED, the luminous chip can not cut corners;

2. Adopt high-efficiency switching power supply, greatly improving the power conversion efficiency;

3. Carry out excellent cooling design of the screen body to reduce the power consumption of the fan;

4. Design scientific integrated circuit scheme to reduce power consumption of internal circuit;

5. Adjust the brightness of outdoor LED display automatically according to the change of external environment to achieve the effect of energy saving and emission reduction.
