DisplayPort Cheers USB Type-C In To VR Applications

USB Type-C application tentacles extend to virtual reality (VR) in the field. VR application requirements for high transmission interface, Display Port is an ideal choice for one of the few. Display Port supports the USB Type-C through an alternative mode (Alt Mode), homeopathic obtain VR application developers of all ages. LG Electronics has introduced into USB Type-C in its Connected VR device, the future will see more examples of head-mounted VR display equipped with a USB Type-C.

Andre Bouwer, Vice President Analogix market believes that the VR and AR applications, support for DisplayPort USB Type-C interface is the best choice.


Andre Bouwer, vice president of marketing at Analogix support DisplayPort functionality USB Type-C connector is PC and smartphone manufacturers to use leadership, especially supports high-performance audio and video specifications of the end product, the use of this interface is even more demand ardent. It is foreseeable that, in a variety of application scenarios USB Type-C can be supported, the proportion of the use of video transmission will become increasingly high, especially in the VR and AR waves, the importance of video transmission will not only increase Less.


In fact, LG Electronics (LG) recently has partnered with Analogix, introduced the use of SlimPort phone and headset VR headset. SlimPort can be regarded as a special version of the DisplayPort is designed for mobile device development, it is also compatible with a USB Type-C.


LG developed a new VR / AR applications, called Connected VR. Compared to the Oculus Rift, HTC Vive VR and other devices to be used with a PC, Connected VR is used with the phone, so that users can always use VR or AR. This convenience can open a new application for the VR and AR may, for example, when users travel in a strange place, you can use AR for traffic routes, attractions and more.


However, support for DisplayPort and USB signal transmission smartphone, we must pay special attention to problems in the design of signal interference. Bouwer noted band USB 3.1, DisplayPort and other high speed interface signals, wireless signals and cell phone used by slightly overlapping, so if the design accidentally, may affect mobile communications. In the design of these applications, devices, designers must carefully deal with isolated winding high-speed interface with the phone antenna.


On the other hand, Bouwer analysis, the human eye is very sensitive to motion pictures, requires a higher frame rate (Frame Rate) and resolution, it will not allow users to feel discomfort. In terms of frame rate of 90 frames per second (FPS) or 120 is an ideal digital; the best resolution you may want more than 8K. Thus, VR is a display interface for high bandwidth requirements of the application, or only a general wireless transmission of traditional USB interface to transfer data, we can not meet their needs. Looking at the current market a variety of interface technology, DisplayPort is the best choice.
