What are the classifications of LED displays?
LED display in the past few years has been a lot of use, it's colorful and diverse can present a more delicate picture texture, so it is widely used in media advertising, large-scale meetings. However, now on the market a wide variety of LED display, quality varies, so that users are facing a wide range of LED display is difficult to make a choice, so what are the specific categories of LED display? The following follow the small editor of Vishay to take a look at it!
I. By pixel density:
The pixel density of LED display refers to the number of pixels per square meter, which is used to distinguish between LED displays with different dot pitches, usually the smaller the dot pitch, the higher the pixel, and the more excellent the video effect displayed.
Second, according to the display performance can be divided into:
Video display: generally full-color displays, such as P4.81 full-color outdoor rental screens;.
Text display: generally single-color displays, such as LEDP10 monochrome screen;
Graphic display: generally a dual-color display, also known as the LED dual-color screen;
Special display: generally for the door head color, such as Led door head full color screen, using P13.33 outdoor external paste module.
Three,It can be categorized by display device:
LED digital display: the display device is a 7-segment code digital tube, suitable for the production of clock screen, interest rate screen, etc., showing the digital electronic display.
LED Dot Matrix Graphic Display: The display device is a dot matrix display module consisting of many uniformly arranged light emitting diodes, suitable for broadcasting text and image information. For example, 3.75 indoor dot-matrix monochrome board, 5.0 indoor dot-matrix monochrome board, 3.75 indoor dot-matrix dual-color board, 5.0 indoor dot-matrix dual-color board.
LED video display: the display device is composed of many light-emitting diodes, which can display video, animation and other kinds of video files.
Conventional LED display: the use of steel structure will be installed in a position fixed display. The main common outdoor large single column LED advertising screen, as well as the station installed on the wall to play the number of trips on the wall of the single, two-color LED display screen.
Special LED displays: When designing, the R&D department takes into account the different needs of the market and designs LED spherical displays, LED mirror screens, LED cylindrical displays and LED shaped displays.
Fourth, according to the use of the environment can be divided into:
1, semi-open air curtain between indoor and outdoor, and high brightness, in this case can be used outdoors, generally speaking, the screen is sealed and used in the roof or window.
2, the indoor screen area point spacing will be relatively small, the price will be more expensive than the outdoor screen, so generally very small (more than ten square meters). And viewing distance in a few meters away, because it is indoors so do not have to open air, the screen can not have sealed waterproof function.
3, the outdoor display area is usually larger, smaller than a dozen square meters, large hundreds or even thousands of square meters, point density is sparse and luminous brightness in 3000-6000cd/square meter. In direct sunlight conditions viewing distance of tens of meters, because it is outdoor, so must use waterproof box, in case of uncertainty about the bad weather. Roughly we can distinguish from these points above!
LED electronic display adopts a low-voltage scanning drive, with power consumption, long service life, low cost, high brightness, large viewing angle, visual distance, waterproof, specification varieties, etc., can meet the needs of a variety of different application scenarios, the development prospects are very broad, is recognized as the most growth potential is also the fastest growing LED application market. And in the future of the large sports events and other new demand, will prompt the large-scale development of LED display. In addition, has erected a large LED display screen every 10 years will experience a replacement tide, with the improvement of people's living standards, outdoor led display screen will be gradually applied to various industries.
The above about what classification of LED display screen for you to share here, in the LED display technology continues to innovate under the development trend, its application scenarios unlimited expansion, in the field of immersive experience display, theLED displayIt shows certain feasibility and not bad application prospect, let's wait and see.
