1.indoor, outdoor and semi-outdoor LED display
The area of indoor led display ranges from 1 square meter to tens, even hundreds. Indoor led display will be used in a building. For the indoor led signs, with the feature of modest brightness, wide visual angle, short distance of mixed color, lightweight, high density, it makes the indoor led panel suitable for people to view the screen closely. The area of outdoor led panel ranges from tens of square meters to dozens, even hundreds. It can be used in direct sunlight. The viewing distance is up to dozens of meters. The body of the screen is water-and-wind proof; it also has lightning protections. Semi-outdoor led display is the one which falls in between. It has a much higher brightness, and can be used outdoors where there is out of direct sunlight. The body of the screen is with airtight seals.
2.Divided by color: Monochrome LED display, double-colour LED display and tri-phosphor LED display
Monochrome LED display means the screen is made of the led with one color, usually the color is Red. It is yellow or green on some special occasion. Double-colour LED display means the screen is made of the led with two colors---red and green. Double-colour LED display with 256-level gray scale could show 65,536 colors. Tri-phosphor LED display, also called full-color led display, is made of led with three colors-- red, green, blue. It could show the white balance and 16,777,216 colors.
3、Divided by control mode: Synchronization mode and asynchronization mode
Synchronization mode means the working mode of the led display is just like the computer monitor. It updates the image at the refresh rate of 30 chang/s, usually it shows the color with multi gray scale. It is good to do multi-media advertising.
Asynchronization manner means the led display has the ability to store and autoplay. After editing the text and image on the computer, transfer them to led display via serial port or other network interface, and then the led display will play them automatically. It doesn’t display the color with multi gray scale, so it usually used to showing text message. It can be connected to the network with multi-window play.
