In the industrial display industry, as an expansion interface, there are many types. Different interface types can meet different or diverse connection requirements, and are also one of the tools for compatibility and performance between devices. Among them, DVI (Digital Visual Interface), as a classic and effective video interface, still occupies an important position in many industrial applications with its stable performance and high-quality transmission capabilities, high-resolution support and compatibility. Let’s take a look at its technical characteristics, application scenarios and its important role in industrial displays.
DVI is a common video interface that is widely used in computer monitors and industrial display devices. There are three main types of DVI interfaces, which can be divided into DVI-D (Digital), DVI-A (Analog), and DVI-I (Integrated) according to the supported signal types. DVI-D only transmits digital signals and is suitable for connecting digital displays (such as LCD screens). DVI-A (Analog) can transmit analog signals and can be used to be compatible with display devices with VGA interfaces. DVI-I can support both digital and analog signals. Therefore, digital displays can be connected, and analog displays can be connected through adapters.
DVI has many advantages, one of which is that it supports lossless digital signal transmission, with clear pictures and accurate colors. In addition, due to the strong compatibility of DVI, the DVI-I interface can support digital and analog signals and is compatible with VGA devices. High stability. In addition, the DVI interface is sturdy in design, suitable for the stable connection requirements of industrial environments, and can also be suitable for harsh application environments. The disadvantages of DVI are also obvious, that is, there is no audio transmission, so it can only transmit video signals, does not support audio, and requires additional audio cables.
One of the application scenarios of DVI is as an industrial display. Because of its stability, it can be used to connect industrial computers, industrial monitors and display terminals. In addition, DVI can be used for some scenarios with high requirements for color reproduction, such as graphic design, architectural design, mechanical drawing, geological exploration and video production. In addition, DVI is equipped with dual channels, so it supports high resolution and can be used in scenarios suitable for CAD, GIS, medical display equipment, traffic and security monitoring, etc.
