What is the light pollution of   LED advertising trucks? First, the light emitted from the liquid room of the display screen is too strong, which seriously affects the driving safety of the truck driver; the second display screen disturbs the people, the light at night is weak, and the light emitted by the display screen is too dazzling. If the mini LED advertising truck is disgusting, the information it disseminates will not be understood by the broad masses of people, and the publicity effect will not be achieved. Is there any way to solve it?

1. Adopt a brightness adjustment system that can be automatically adjusted by the system

Through the outdoor brightness collection system, the ambient brightness can be collected at any time. The display screen control system automatically converts the broadcast brightness suitable for the environment through the software by receiving the system data.

2. Multi-level gray scale car positive technology

3 side screen display truck is hot selling. The LED display control system adopts 14bit color display level, which greatly improves the hardness of the color. So that people can feel the color soft when watching. Avoid people's discomfort with light.

3. Reasonable selection of installation location and reasonable planning of display area

There is an empirical plan for viewing distance and viewing angle and display area, and image research has specific design requirements for display viewing distance and viewing angle. When designing the display screen, it should meet the design requirements as much as possible, and plan reasonably.

4. Selection and design of content to be played

The large LED screen is a public medium, including public welfare, advertising, and instruction. When we choose the content to be broadcast, we must reach an agreement with the public's requirements to avoid the psychological refusal to watch. This is also an important aspect of preventing and controlling the light pollution of the display screen.

The above is how to prevent LED advertising trucks from producing light pollution. LED diodes themselves are green light sources. Although large-scale LED display screens used in clusters do cause a certain degree of color light pollution due to design considerations and application requirements, but this kind of contradiction is inevitable and cannot be completely eradicated. Only by adopting technical means and policies and regulations to minimize color light pollution, and to coordinate the needs of advertisers and the people's viewing psychology.
