Vx1 Display Interface: Definition and Advantages

This page covers the basics of the Vx1 display interface, which is used for image transfer. It also highlights the benefits and advantages of the Vx1 interface.

Introduction:

There are several common display interfaces used for image transfer, including LVDS, RGB, MIPI, Vx1, and eDP. We’ll dive into the Vx1 interface, covering its core principles, advantages, and disadvantages.

What is Vx1 Display Interface?

This interface, developed by Thine Electronics, shares similarities with LVDS and MIPI interfaces. It’s employed in large, high-resolution screens like 55-inch 4K TVs.

Vx1 (V-by-1) is a low-voltage differential interface designed for high-bandwidth image transfer. It efficiently supports displays with higher resolutions and refresh rates.

Its versatility makes it suitable for a wide range of applications, including:

• Document processing
• Industrial cameras
• Machine vision
• Robotics
• Automotive infotainment systems

In this interface, the clock signal is embedded within the data wires, eliminating the need for separate clock wires.

Benefits or Advantages of Vx1 Interface

Here’s a rundown of the benefits and advantages of the Vx1 interface:

• Differential Interface: Offers inherent noise immunity.
• High Speed: Supports speeds up to approximately 3.75 Gbit/sec per pair.
• Cost-Effective: Compatible with inexpensive twisted pair cables and connectors.
• Skew Problem Solution: Addresses skew problems seen in LVDS by utilizing CDR (Clock Data Recovery).
• EMI Resistance: Exhibits greater resistance to EMI (Electromagnetic Interference) compared to LVDS.
• Reduced Wiring: Requires fewer wires as the clock signal is transmitted along with the data.
• Distance: Supports a distance of 10 meters with each differential pair at a data rate of 840 MB/s.
