Since the development of touch technology, capacitive touch displays have spread rapidly in our lives and can be seen almost everywhere in recent years. We all know that capacitive touch displays are also a type of electronic products, mainly used to display images. When using them, they must be connected to other devices through interfaces. Therefore, if you need to buy capacitive touch displays, you must clarify what interface you need. When purchasing a capacitive touch display, the company must first determine what kind of interface the customer needs, so what interfaces are currently available on the capacitive touch display on the market?
1. VGA interface
VGA, also known as Video Graphics Array, is a video transmission standard that IBM once introduced in a computer. Although the computer has long been eliminated from the market, gold always shines, and the VGA interface has become the most used type by suppliers. Because of its high resolution, fast display rate and rich colors, it is widely promoted in the field of color displays. At present, most of the products of the Microsoft windows system still use VGA for boot display, which shows its importance. This interface does not support audio transmission and does not support hot plugging.
2. DVI interface
DVI, also known as Digital Video Interface, is an interface standard invented by the Digital Display Working Group established by several companies on the Intel Developer Forum. Digital signal is a transmission mode that is widely used and understood by people now. It can realize long-distance and high-standard digital signal transmission with low-cost cables. TVs, DVDs, projectors, etc. that we are familiar with all use this kind of interface.
It is worth mentioning that DVI can be subdivided into three different types of interfaces: DVI-A, DVI-D and DVI-I. In addition to DVI-A, the other two are single-channel and dual-channel. .
3. HDMI interface
HDMI interface, this interface is very common, like TV and computer, but many people do not know its specific function, it is also called high-definition multimedia interface, it is a digital video and audio interface, which can transmit video and audio at the same time. The HDMI interface is a transmission mode jointly developed by seven leading companies in the electronics industry in various countries in 2002. The purpose is to replace the DVI interface and achieve the goal of overall industry renewal. Until now, this interface is still the mainstream in the industry.
4. DP interface
DP is a high-definition digital display interface. It was launched by the Video Electronics Standards Association in 2006. After many optimizations, it has also won the support of many industry leaders, so it has been promoted, and it is free to use. The DP interface can be connected to a computer and a monitor, which can integrate peripheral devices to the greatest extent.
5. LVDS interface
LVDS interface, also a digital signal video transmission method, is a low-voltage differential signal technology interface used to solve the problem of noise and electronic interference during data transmission. The limitation of the LVDS interface is that it is only suitable for displays over 7 inches, so it cannot be used on small-sized displays.
The above are the five common capacitive touch display interfaces on the market. When purchasing a product, you must first clarify your needs and know what interface you want to buy. If you are not sure, you can consult the company to avoid wasting time and energy by buying the wrong product. In fact, the consulting services of large companies are very thoughtful now. Friends in need can consult Top One Tech. The company not only provides customers with thoughtful consulting services, but also can customize different capacitive touch display interfaces for customers.
