With the development of LED display technology, the application range of LED display screens has become wider and wider, and there are more types. Whether it is indoors or outdoors, we often see LED display screens, and they are of different shapes, and can be made into various indoor and outdoor decorations, making the decorations beautiful.


So, what kinds of led displays are there?


1) Divided by application field: LED display can be divided into outdoor LED display and indoor LED display. The main difference between the two displays is that the outdoor LED display is relatively waterproof and dustproof, and the brightness is relatively large; while the indoor LED display is relatively less waterproof and dustproof, and the brightness is relatively dark. . In addition, the pixel pitch of outdoor LED displays is generally larger than that of indoor LED displays, but now the outdoor is also beginning to develop in the direction of small pitches. Presumably in the future, the difference between outdoor and indoor LED displays will not be too great. big.

2) Divided by pixel pitch: can be divided into P0.95, P1.26, P1.583, P2, P2.5, P3, P3.81, P3.91, P4, P5, P6, P6.67, P8, P10, P16 and so on. In general, LED displays with a dot pitch above P4 are often used outdoors, while LED displays with a dot pitch below P4 are often used indoors. This is mainly determined by factors such as viewing distance and cost. The viewing distance in the outdoor area is generally relatively far, even if the pixel pitch is large, it will not affect the viewing effect of the video; while the indoor viewing distance is relatively close. For those with large spacing, The screen will appear "grain", which affects the viewing effect, so indoor LED displays often choose smaller spacing. The other is the cost. In the same configuration, the smaller the spacing, the more LED lamp beads will be used per square meter, and the corresponding electronic components will increase accordingly, and the cost will naturally increase. Therefore, in In the case of not affecting the viewing effect, choosing a LED display with a larger spacing in the outdoor field is also a way to control the cost.


3) Divided by usage scenarios: it can be divided into fixed led display, rental led display, creative led display, small pitch led display, LED floor tile display, LED special-shaped display and so on. Fixed-mounted led display, that is, fixedly installed in one location, and will not move for a long time. It can be an outdoor led display or an indoor led display; rental led display, namely Used for frequently rented led display screens. The main features of this type of display screen are that it is easy to install, disassemble, and transport. The weight of a single box is relatively light, and there are anti-collision protection corners around the box. Such displays need to be frequently installed, disassembled and moved, and are often used in stage interpretation, fashion shows, exhibitions, advertising, caravan displays, concerts, evening events, etc.


4) According to the display color: it can be divided into monochromatic LED display, two-color LED display, and three-color (full-color) LED display. Monochrome means that the display has only one color of luminescent material, mostly single red; dual-color screens are generally composed of red and green LED diodes; three-color (full-color) screens are composed of red, green (wavelength 570nm), and blue Color composition; and true color, composed of red, pure green (wavelength 525nm), and blue.


5) Divided by display function: LED display can realize interactive experience, immersive experience, stereo display, naked eye 3D, VR/AR... The specific effects can be completed according to your own needs, so the display effect is also very powerful.


6) Divided by packaging methods: LED displays have direct insertion, surface mount (SMD), and COB; in the past, when the dot pitch was P20 and 30, direct insertion was the main way to go crazy for led displays, but as users The requirements for led displays have become higher. SMD has reduced the dot pitch of led displays to 1.25, and the cob package can easily achieve dot pitches below 1.0mm. Nowadays, direct-plug led displays are rare, and they are all SMD and COB. SMD is still the mainstream and relatively complete, but the cob display is the future trend.


Of course, LED display screens can be divided into many other ways according to other methods, such as LED interactive screens, LED cube screens, LED spherical screens, LED light pole screens, etc. However, our commonly used classifications are the ones mentioned above. And it is several classifications that are often used in the LED display industry. The LED displays introduced above are produced by Lianchengfa, with powerful functions and stable performance.
