How are LED displays classified, do you know? The following LCF editor (www.lcf-led.com) will introduce it to you.  

1. Features of intelligent and functional LED display: The intelligent LED display usually does not need to be connected to the computer host. The LED display has a built-in CPU, which can save multiple pictures when power off, and can run independently from the computer host. Some screens and clock chips that automatically display the date and time. When it is necessary to modify the display content, it can be modified by connecting the computer through the RS-232 interface. The full-featured LED screen must be connected to the computer host to work; the intelligent LED display usually has fewer display modes, such as pull-screen, pop-up, scroll-up and scroll-down. The full-function display has various display methods. If you use professional software to create and broadcast programs, there are infinite display methods; the intelligent LED display is easy to operate, and the full-function LED display needs to be operated and maintained by a special person. The production of animation programs requires specialized knowledge.


2. Indoor, outdoor and semi-outdoor LED display: The area of indoor LED display generally ranges from less than one square meter to more than ten square meters, with a high point density. In direct sunlight or ambient lighting, the viewing distance is a few meters away, and the screen The body does not have the ability to seal and waterproof. Indoor LED displays are generally dominated by dot-matrix modules, because the display brightness requirements for indoor use are not high, and dot-matrix modules have a high price; outdoor LED displays are generally from several meters to tens or even hundreds of square meters. The point density is relatively thin, mostly 1000-4000 points per square meter, and the luminous brightness is 3000-6000cd/square meter. Different orientations have different brightness requirements. In direct sunlight, the viewing distance is tens of meters, and there is a good resistance on the screen. Wind, rain and lightning protection ability; semi-outdoor LED display is between indoor and outdoor, high brightness, can be used outdoors in the sun, the screen is sealed, usually on the roof or window.


3. Monochromatic, dual-color, tri-primary LED display: Monochromatic LED display refers to the luminescent material with only one color in the display, mostly single red; dual-primary LED display is generally composed of red and yellow-green luminescent materials The three-primary color LED display is divided into full-color and true-color displays. Full-color is composed of red, green, and blue, while true color is composed of red, pure green, and blue.
