What is Vx1 display interface | Advantages of Vx1 interface

This page covers Vx1 display interface basics used for image transfer. It mentions benefits or advantages of Vx1 interface.

Introduction : There are various common display interfaces viz. LVDS, RGB, MIPI, Vx1 and eDP used for image transfer. We will understand Vx1 interface basics, its merits and demerits.

What is Vx1 display interface ?

This interface is developed by Thine Electronics which is similar to LVDS and MIPI interfaces. It is used in large high resolution screens such as 55 inch 4K TVs. It is low voltage differential interface.

Vx1 (V by 1) interface is used for high bandwidth image transfer. It supports higher resolution and higher refresh rate displays. It is used in wide variety of applications which include document processing, industrial cameras, machine vision, robotics, automotive infotainment systems etc.

Vx1 interface

In this interface, clock signal is transferred through data wires. There are no separate wires for clock signal.

Benefits or advantages of Vx1 interface

Following are the benefits or advantages of Vx1 interface:
➨It is differential interface.
➨It supports higher speeds (about 3.75 Gbit/sec) for each pairs.
➨It is used with inexpensive twisted pair cables and connectors.
➨It solves skew problems observed in LVDS interface using CDR (Clock Data Recovery).
➨It is more resistant to EMI (Electromagnetic Interference) than LVDS.
➨It requires less number of wires as clock is transmitted with data.
➨It supports distance of 10meters with each differential pairs at 840 MB/s data rate.
