The LED industry is a “light-making” industry. Due to the brightness problem of LED display screens, one of the “manufacturers” that produces light pollution. At present, because there is no regulatory restriction, when night falls, many outdoor LED displays compete to light up, and at the same time, the brightness emitted by them has caused a certain degree of light pollution to the surrounding environment and brought invisible damage to the lives of surrounding residents. As an LED display manufacturer, how to solve the "light pollution" problem caused by the LED display? Let's take a look at it together.
1. Adopt a brightness adjustment system that can be automatically adjusted by the system
We know that the brightness of the environment at different times and locations varies greatly during the day and night. If the playback brightness of the LED display is greater than 60% of the ambient brightness, we will obviously feel that the eyes are not suitable, that is to say, it is harmful to people. light pollution. Through the outdoor brightness collection system, the ambient brightness can be collected at any time. The display level control system automatically converts the broadcast brightness suitable for the environment through the software by receiving the system data.
2. Multi-level grayscale correction technology
The 8bit color display gradation adopted by the ordinary display screen system, so that the color is stiff in some low grayscale and excessive color. It will also cause inadaptability of colored light. The new LED large-screen control system uses 14bit color display levels, 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 on the 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 reasonably.
Fourth, the selection and design of the content to be played
The large LED display 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 mentality of refusal to watch it. This is also an important aspect of preventing and controlling the light pollution of the display screen.
The LED diode itself is a green light source. Although the large-scale LED display screens used in clusters do cause a certain degree of color light pollution, this 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. At the same time, we have also seen that compared with today's neon and white light box advertisements, the light pollution of LED displays has been greatly reduced. Moreover, the LED electronic display has the advantages of energy saving and rich colors, and it will definitely replace the neon light outdoor lighting and information display.
