What are the common interfaces for LED roll-up screens?
As we all know, in order to meet the needs of different applications, there are a lot of interfaces, these interfaces have different shapes and different advantages and features, can be used for different occasions and products to meet a variety of display effects and needs. Then you knowLED Roller ShutterWhat are the common interfaces of the screen? The following Vishay Technology editorial for your introduction:
The interfaces commonly used for LED roll-up screens are as follows:
1、DVI interface
DVI (Digital Visual Interface) interface, that is, the digital video interface, DVI can transmit digital signals, do not have to go through the digital-analog conversion, so the picture quality is very high.LED roller shutter screen DVI interface, is now the international common a digital video signal interface. Currently there are two common DVI interfaces, respectively, DVI-Digital (DVI-D) and DVI-Integrated (DVI-I), DVI-D only supports digital signals, while DVI-I not only supports digital signals, but also supports analog signals, that is to say, DVI-I compatibility is stronger.
2、VGA interface
VGA (Video Graphic Array), Video Graphic Array, VGA interface that the computer using VGA standard output data dedicated interface, a total of 15 pins, divided into three rows, each row of five holes, is the LED roll-up screen graphics card on the widely used interface types, the vast majority of graphics cards with such interfaces. It transmits red, green and blue analog signals and synchronous signals (horizontal and vertical signals).
3、SDI interface
SDI interface is an acronym for "serial digital interface". Using coaxial cable, BNC interface as the cable standard. That is to say that we have a traditional analog frame system into a high-definition monitoring system in the process, LED roller shutter screen without rewiring, only need to replace the front end and back end part, which will save a huge amount of time for the project cost and labor costs. Therefore, in recent years, the use of SDI interface in the LED roller shutter screen processor gradually increased.
4、USB interface
USB abbreviation is UNIVERSAL SERIALBUS, translated into Chinese that is: Universal Serial Bus, also known as Universal Serial Interface.LED roller shutter screen USB interface can support hot swapping, can connect 127 PC external devices: there are USB1.0 and USB2.0 two interface standards.
5, HDMI interface
HDMI is a new generation of multimedia interface standards, the full name is High-Definition Multimedia Interface, Chinese meaning high-definition multimedia interface. It is the same with DVI is the transmission of all-digital signals, the difference is that HDMI can not only meet the 1080P resolution, but also supports digital audio formats, that is to say, a line to achieve synchronized transmission of video and audio. It can be said that the HDMI interface of the LED roller shutter screen is an improvement of the DVI interface, it is fully compatible with the DVI interface standard.
In summary, we can see that the LED roller shutter screen commonly used interfaces are mainly DVI interface, VGA interface, SDI interface, USB interface, HDMI interface five, you can choose according to their actual needs.
