First, the use of system can automatically adjust the brightness adjustment system
We know that during the day and night, the brightness of the environment varies greatly at different times and locations. If the brightness of the China LED Screen Suppliers is greater than 60% of the ambient brightness, we obviously feel the discomfort of the eyes, which means that it causes light pollution to people. Through the outdoor brightness acquisition system, the ambient brightness is collected at any time. The display level control system automatically converts the broadcast brightness suitable for the environment by software by receiving system data.
Second, multi-level grayscale correction technology
The average display system uses an 8-bit color display level so that the colors are stiff at some low gray levels and excessive colors. It also causes the incompatibility of colored light. The new Advertising LED Display Screen control system uses a 14-bit color display layer, which greatly improves the hardness of the color in excess. Make people feel soft when watching. Avoid people's discomfort with light
Third, the reasonable choice of installation location and reasonable planning of the display area
There is an empirical plan for viewing distance and viewing angle and display area, while image research has specific design requirements for viewing distance and viewing angle of the display screen. When designing the display screen, it should meet the design requirements as much as possible and plan properly.
Fourth, the selection and design of the content
The led message board is a public media, with public welfare, advertising, and instructional categories. When we choose to play the content, we must agree with the public request to avoid refusal. This is also an important aspect of preventing display light pollution.
The LED diode itself is a green light source. Although it is caused by a design consideration and application requirements on the large-scale LED display screen of the cluster type, this kind of contradiction is inevitable, and It cannot be completely eradicated. Only by using technical means and policies and regulations to minimize the pollution of color light, coordinate the needs of advertisers and the public's viewing psychology. At the same time, we also see that compared to today's neon and white light box advertising, the light pollution of LED display has been greatly reduced. And led wall panels also has the advantages of energy saving and rich color, it will be a comprehensive alternative to neon outdoor lighting, information display.
