The Solution to LED Screen Light Pollution

  The international general LED display light pollution into 3 categories, that is, white pollution, artificial daylight and color light pollution. At present there is no relevant regulation on artificial daylight and color light pollution.

  However, considering the color light pollution does cause people feel unwell, so in the design of LED display screen should be taken into account to display screen light pollution prevention and control problems.

  First, the use of system automatic adjustment of the Brightness control system

  We know that day and night, different time and place environment of the brightness changes greatly, if the outdoor LED screen  brightness greater than the ambient brightness of 60% we will obviously feel the eye is not adapted, that is to say, caused the light pollution to people. Through the outdoor Brightness collection system, at any time to the ambient brightness collection.The display of the flat control system automatically converts the brightness of the broadcast to the environment through the software of the receiving system.

  Second, multilevel gray correction technology

  The ordinary LED display system uses the 8bit color display level, so in some low grayscale and color excessive color blunt. It can also cause the color light to be not adapted. The new LED big screen control system uses the 14bit color display level, greatly improves the color in excessive hardness. So that people can feel the soft color when watching.Avoid people's discomfort with light.

  Third,Reasonable selection of installation position and rational planning of display area.

  Viewing distance and viewing angle and display area have an experience planning, at the same time image research in the screen viewing distance and viewing angle has specific design requirements.

  Fourth,In the display design should be as far as possible to meet the design requirements, reasonable planning.

  Selection and design of broadcast content LED display screen is the public media, there are public welfare, advertising, such as indicators. When we choose to play the content, we must agree with the public demand, avoid the refusal to look at psychology.

  This is an important aspect of controlling the light pollution of the display screen. LED diode itself as a green light source, although in the cluster-type application of large giant LED display on the screen because of the design considerations and the application of the requirements did cause a certain degree of color light pollution, but this contradiction is inevitable, and can not be completely eradicated. Only the use of technical means and policies and regulations to minimize color light pollution, to coordinate the needs of advertisers and the people watching psychology. At the same time, we also see relative to today's neon lights and white light box ads, LED display light pollution has been greatly reduced. and led electronic display also has energy-saving and rich color advantages, will be a comprehensive replacement of neon lights outdoors, information display.
