  •      The advertising machine is a new generation of intelligent devices, which constitute a complete advertising broadcast control system through terminal software control, network information transmission and multimedia terminal display, and through multimedia materials such as pictures, texts, videos, small plug-ins (weather, exchange rates, etc.). Advertising.

  •      There are many types of advertising machines. Among them, the LCD display is a common one. It has many parameters. It is a very headache when you want to buy people who know the parameters but don’t know where to start. Today we come. Introduce the gamut coverage of the LCD display. A gamut is a range of areas formed by the number of colors that a display system can express.

  •      So, what is the color gamut coverage of the LCD display? KONWHAI Xiaobian analyzes the solution for you.

  •      In order to more intuitively represent the concept of color gamut, the CIE International Lighting Association has developed a CIE-xy chromaticity diagram. In this coordinate system, the gamut range that each display system can represent is represented by a triangular area composed of RGB three-point lines. The larger the area of ​​the triangle, the larger the gamut range of such a display device.
  •  
  •      The gamut coverage refers to the horseshoe-shaped chromaticity triangle marked with color on the CIE-xy chromaticity diagram, which is the color area that can be seen by the human eye. If the LCD display is able to fully display the color in this horseshoe-shaped area, it indicates that its color gamut coverage is 100%.
  •  
  •      When the colors are reproduced by the three primary colors of R, G, and B, the triangular regions composed of the three primary color coordinates of R, G, and B are the color reproduction regions determined by the three primary colors, and the ratio of this region to the horseshoe region is the color gamut coverage.
  •  
  •      Everyone should understand this. The so-called color gamut coverage is actually the ratio of the area of ​​the triangle area composed of a certain R, G, and B primary color coordinates to the area of ​​the three basic color coordinates of the standard R, G, and B.
