LED display screen from the original monochrome display, two color display screen, three basic color display screen, to today’s multi-color display, has accumulated a variety of color processing technology, become one of the core technologies of LED display. The following Mini photoelectric small coder and everyone to learn about it.
1. The allocation of white field color coordinates: the white field color coordinate deployment is one of the most basic technologies of full color LED display. Many LED display manufacturers have started to standardize the color matching technology of full color screen. However, some manufacturers often use the gray level of some basic colors to allocate white field color coordinates, so that the comprehensive performance can not be improved.
2. The selection of basic color wavelength: LED display screen has been widely used in various fields with its own characteristics. The basic color wavelength of LED required in different fields is different. How to choose the basic color wavelength of led to achieve better visual effect is determined according to the use situation and situation.
3. Color reduction processing: the birth of pure blue and pure green LED makes the full color LED display screen be sought after by the industry for its wide range of color range and high brightness. When displaying the skin color of human beings, there is obvious visual deviation. Therefore, color reduction processing technology emerges.
The so-called static screen in LED display design is corresponding to the dynamic screen (scanning screen). Static screen means that when the display screen is displayed, all the light points are on at the same time. The scanning screen is to use the visual retention of human eyes, and light up the LED electronic display lines in a short period of time.
LED display is driven by duty cycle, so the brightness of the display has a great relationship with the time period of illumination. In the case of the same luminescent tube brightness, the static screen is higher than the dynamic screen, so the static screen is used for outdoor screen and dynamic screen for indoor screen to save driving cost.
