There are many different ways to classify LED all-in-one machines, only four of which are described here, as follows.
Classification By The Use Environment Of LED All-In-One Machine
LED all-in-one machines can be divided into indoor LED all-in-one machines, semi-outdoor LED all-in-one machines, and outdoor LED all-in-one machines according to the use environment. Indoor LED all-in-one machines for indoor use The area is generally small, with high dot density and small diameter of luminous dots, generally Φ3mm ~Φ 8mm. can be viewed a few meters away. Outdoor LED all-in-one machines are the opposite, the area is larger, the screen body point density is thinner, and the diameter of the luminous point is large, such as Φ10 mm, Φ12 mm, Φ16 mm, Φ19 mm, Φ21 mm, Φ26 mm can be viewed several dozen The screen can be viewed from tens of meters away. Semi-outdoor LED all-in-one machines are in between.
Classification By LED All-In-One Machine Pixel Pitch
LED all-in-one machines' pixel pitch is the distance from the center of one pixel to the center of another pixel. The indoor screen uses LED dot matrix specifications that are relatively uniform, generally for P3mm, P 4.75 mm, P 6mm, P 7.62 mm, P8mm, and so on. The outdoor screen is generally P10 mm, P12 mm, P16 mm, P20 mm, P25 mm, etc.
Classification By The Color Of The LED All-In-One Machine
LED all-in-one machines can be divided into single-color displays, two-color displays, and three-color displays according to the color of the screen body. Monochrome displays can only display one color, usually red. The currently used two-color display is generally composed of red and yellow-green light-emitting materials. Three color displays can be divided into full color and true color.
Classification By The Control Mode Of LED All-In-One Machine
LED all-in-one machines can be divided into synchronous control all-in-one machines and asynchronous control all-in-one machines according to their control methods. Synchronous control means that the LED all-in-one machine is basically equivalent to the monitor of the computer, which can map the images on the computer monitor in real-time to achieve the effect of multimedia publicity. Asynchronous control means that the display has its own storage and automatic playback function, and the text and pictures edited on the computer are transmitted to the LED all-in-one machine through the network interface, which is automatically played offline by the LED all-in-one machines. screen offline automatically plays.
