Description

Adapter between DP interface and Mini DP interface

technical field

The utility model relates to the technical field of DP adapters, in particular to an adapter between a DP interface and a Mini DP interface.

Background technique

With the popularity of digital liquid crystal displays, the video interface is also actively digitized.

DP interface integrates video and Audio signal transmission, and the interface is small in size, has good flexibility and convenience, and supports higher resolution and refresh rate at the same time. It has become one of the interface standards generally favored by the industry in the field of digital display.

The DP interface can be used for home appliances and computers. In order to make the DP interface available for thinner electronic devices such as laptops and smart phones, the Mini DP interface has been developed on the basis of the DP interface, which is smaller in size and , In February 2011, Intel integrated two mature technologies of PCI Express data transmission technology and Display Port display technology, and launched the Thunderbolt super high-speed interface (also known as Thunderbolt interface), which is mainly used to connect PCs and other devices. The physical appearance of the Thunderbolt interface is the same as that of the Mini DP interface, suitable for various light and small devices, and compatible with the Display Port interface.

For the above interfaces, generally, the female end is set on the electrical equipment, and the male end is set on the connecting line. Due to the difference between standard DP and Mini DP, users cannot use general-purpose data lines for connection, but need to use DP interface and Mini DP respectively. The data line of the interface causes great inconvenience in use.
