Monochrome LED display: monochrome LED display refers to the display only one color of luminous materials, mostly single red.
Two-color LED display: two-color LED display is generally composed of red and yellow-green luminous materials.
Three, three basic color LED display: three basic color LED display is divided into full color, true color display, full color is composed of red, green, blue, and true color is composed of red, pure green, blue.
4. Indoor LED display: the area of indoor LED display is generally from less than 1 square meter to more than 10 square meters, with high point density. In direct sunlight or ambient lighting, the viewing distance is a few meters away, and the screen body is not equipped with sealing and waterproof ability.Indoor LED displays are generally dominated by lattice modules. Because the display brightness required for indoor use is not high, lattice modules have a high price.
Five, outdoor LED display, outdoor LED display area is generally from several meters to dozens or even hundreds of square meters, the point density is thin, is 1000-4000 per square meter, luminous brightness in 3000-6000 CD/m2, towards different, different brightness requirements, in direct sunlight conditions, viewing distance tens of meters, on the screen has a good ability to resist wind, rain and lightning protection;
6. Semi-outdoor LED display: semi-outdoor LED display is between indoor and outdoor, with high brightness and can be used outdoors in sunlight. The screen body is sealed, usually on the roof or window.
7. Intelligent LED display: the intelligent LED display does not need to be connected to the computer host at ordinary times. The LED display has a built-in CPU, which can save multiple pictures when power is lost and operate independently from the computer host.Some screen and clock chips can automatically display the date and time.When the display content needs to be modified, it can be modified by connecting the microcomputer through the rs-232 interface.The full-function LED screen must be connected to the main computer to work;Intelligent LED displays usually have fewer display modes, such as pull-screen, pop-up, up-roll and down-roll.
8. Functional LED display: the display mode is diversified. If the program is produced and played with professional software, the display mode is infinite.The operation of the intelligent LED display is simple, while the full-function LED display needs to be operated and maintained by a special person. If animation programs are to be produced, special knowledge is also required.
The above is a summary of the classification standard of LED display.
