The market development status of D-SUB connector and VGA interface is detailed!

The actual purpose of the D-SUB connector is to cooperate with the VGE interface to maximize its value. For this reason, the developers of Taiwan connector manufacturers have launched the VGA D-SUB input interface, which is the most advanced and widely used D-SUB connector at present. This article Huichengyuan connector manufacturers mainly share with you the market development status of D-SUB connectors and VGA interfaces!

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

From the appearance, the VGA D-SUB input interface has 15 pinholes, arranged in 3 rows, 5 in each row, which is different from the D-15 interface used by ordinary PC graphics cards. While they both use D-shaped 15-pin sockets, the D-15 interface clearly wastes more pin value compared to the VGA and D-SUB connector inputs, which can cause gaps in the input signal and greatly reduce the quality of the displayed image. The reason why all computers and TVs now use VGA and D-Sub connector input interfaces is because the monitor needs to digitally process the image, which when it passes through the graphics card, is converted to an analog signal. In this process, the VGA and D-Sub input interfaces can do this perfectly, greatly reducing image loss and distortion. Therefore, VGA and D-Sub interfaces produced by Taiwanese connector manufacturers occupy an unshakable position in analog CRT displays. However, with the advancement of technology, CRT displays are gradually replaced by display devices such as LCD and DLP, which means that mainstream displays have changed from digital to analog signal demand to analog to digital conversion demand. Due to this change, the input interface of D-Sub connector, which was originally widely used, has been greatly impacted. Due to multiple D/A and A/D conversion processes, the input interface of D-Sub connector will inevitably cause image quality degradation. This means that it directly gave up the top spot in the market and gave up the advantage to interfaces such as DVI connectors. Looking at the bigger picture, the market has gotten rid of the monopoly of D-Sub connector interfaces, and the market for D-Sub interfaces is declining. In order to keep the market share of VGA and D-Sub connector interfaces, the corresponding Taiwan connector manufacturing company engineers and professionals must find the right direction to improve the technology of VGA and D-Sub interfaces, and only in this way will the connector market continue to grow.
