Micro Coaxial Cable-Micro Coaxial Cable factory-(FRS)-FRS
The evolution of VR and AR headsets is driven by a constant push for higher resolutions (4K/8K per eye), faster refresh rates (90–120 Hz+), and sleeker, lighter designs. This progression places immense pressure on internal high-speed interconnects. Two prominent solutions are micro coaxial cable(often paired with eDP) and LVDS cable. This article dissects their differences and guides you in selecting the right one for your next VR/AR project.
Modern VR/AR headsets are essentially miniaturized computers. Key components include high-resolution OLED/LCD panels, motion sensors, cameras, and SoCs. The primary challenge is routing high-bandwidth video and data from the SoC to the displays through a compact, dynamic structure that bends with head movement.
This is where micro coaxial and LVDS cables come into play. Both are differential signaling technologies that use two conductors to transmit data, offering low voltage swings and excellent noise immunity. However, their implementations and optimal use cases differ significantly.
Micro coaxial cable is a very thin (typically 0.3–0.8 mm OD) coaxial cable. It’s widely used in VR headsets, smartphones, and other compact devices for high-frequency signal transmission.
Key Characteristics:
VR/AR Applications:
LVDS (Low-Voltage Differential Signaling) is a mature technology known for its low power consumption and reliable data transmission over moderate distances. It typically uses twisted pairs, sometimes shielded, and is common in industrial and automotive displays.
Key Characteristics:
VR/AR Applications:
| Feature | Micro Coaxial Cable (eDP) | LVDS Cable |
|---|---|---|
| Signal Rate | Multi-gigabit per second | Typically hundreds of Mbps |
| Max Resolution | 4K/8K per eye | WUXGA and below |
| Pairs per Link | Few (e.g., 4 pairs for eDP) | Many (e.g., 3+1 pairs for LVDS) |
| EMI Shielding | Excellent (individual shields) | Good (overall shield) |
| Bend Radius | Very tight, high-cycle | Moderate |
| Design Complexity | Higher (impedance control critical) | Lower (mature ecosystem) |
| Typical Use Case | Premium VR/AR, high-res displays | Industrial, automotive, cost-sensitive VR/AR |
