Reduce the main way to lead screen light pollution
Today, the bright outdoor led display is widely used. But in the city to enhance the image at the same time, LED display strong light but also on the urban residents of the night life caused a certain negative impact, repeated public criticism. Especially in recent years, LED display "light pollution" problem has gradually been taken seriously, all over the country from time to time complaints case occurred.
According to the identification of the relevant professional departments, the brightness of life in the sun is generally 2000cd, with the outdoor led display technology continues to improve, the current market led outdoor display brightness of 5000cd, or higher, it can be said that the sun Twice the brightness. In the strong light, according to industry insiders, if the outdoor LED display installation position is too low, when the naked eye for the human cornea and iris is likely to cause harm, visual fatigue and vision loss phenomenon, serious even Seriously affect the human brain central nervous system, people feel dizzy, nausea and vomiting.
LED industry is a "light" of the industry, led outdoor display "light production" this is understandable, but from the city's landscape reduced to "light pollution", before and after the evaluation of worlds apart. Therefore, as the LED display business should be in the production should pay attention to "light pollution" problem, from the source to control.
In general, the brightness of the sun 2000CD, when the brightness of more than twice the brightness of the sun, that is, 4000CD, the human eye is completely visible. Outdoor LED display brightness standard is 5000CD, and outdoor display brightness of more than 5000CD will be defined as light pollution. So to grasp the brightness of the set.
1, the system can automatically adjust the brightness adjustment system. We know that day and night, different times and places the brightness of the environment changes greatly, if the LED display brightness is greater than the ambient brightness of 60 percent, we will obviously feel the eyes discomfort, that is caused by the people light pollution. Through the outdoor brightness collection system, at any time on the environment brightness collection, display control system through the receiving system data automatically converted to the environment through the software broadcast brightness.
2, multi-level gray correction technology. Ordinary LED display system uses 8bit color display level, so that in some low gray and excessive color color blunt, will also cause color light is not suited. The new led large screen control system uses 14bit color display level, greatly improving the color in the excessive hardness, so that people feel soft when watching, to avoid people's sense of light discomfort.
