An overview of the value of pairing D-SUB connectors with VGA interfaces!

The so-called D-sub connector is the abbreviation of D-subminiature, also commonly known as VGA (Video Graphics Adapter) interface. The reason why it is called D-subminiature is also because the configuration of D-sub is like a capital letter D. In this article, Huichengyuan connector manufacturers mainly share with you the value of pairing D-SUB connectors with VGA interfaces!

------------------------------------------------------------------------------------------------------

In fact, the development history of D-SUB connector is very long. As early as the mid-20th century, ICC Company, a connector manufacturing company in Taiwan Province, invented a more reasonable interface shape and structure standard through scientific research, thus creating the definition of D-SUB connector. When it was first invented, the interface of D-SUB connector was considered to be the smallest interface in that era, hence the nickname ultra-small, and the name D-subminiature has been named since then. Nowadays, the D-SUB connector ies from Taiwan Province Connector Manufacturing Company is widely used in VGA interface. The so-called VGA interface is actually the interface for outputting analog signals on the graphics card. However, many CRT monitors have a big problem in design, that is, they can only accept analog signal input, but it is too troublesome to output the information processed by the graphics card directly through the monitor. The only way to solve this problem is to let the graphics card input analog signals. Fortunately, the VGA interface can meet the demand, and the most popular VGA (Video Graphics Array) interface on the market operates through the 15-pin D-Sub interface. The VGA interface is closely related to D-Sub, so it is also a D-type interface in configuration. There are fifteen pins at the top, and the layout is arranged in a 3 * 5 structure with three rows and five columns. Of course, the application of D-Sub connector in VGA interface is also remarkable. At present, all graphics cards use the same method, even some graphics cards without VGA interface will be converted by means of connectors, so as to convert effectively to achieve the best effect. However, if the D-SUB connector is used alone without interacting with the VGA interface, the effect of LCD display cannot be achieved, and the image distortion signal will also be caused when the analog signal is converted into output. This also tells us that the reason why D-Sub interface connector manufacturers can gain market share is because of their own value, rather than mainly to exert a certain feature. Only by correctly using D-Sub connectors and VGA interfaces can they exert their maximum value.
