¿Qué es LVDS? La señalización diferencial de baja tensión en monitores industriales

What Is LVDS?

LVDS (Low-Voltage Differential Signalling) is a high-speed digital interface used to transmit video data from a processor or display controller directly to an LCD panel. It uses two wires carrying opposite voltage signals, the receiver measures the difference between them, which makes it highly immune to electrical noise, critical in industrial environments with motors, drives, and switching equipment nearby.

Why Industrial Systems Use LVDS

Unlike consumer displays that use HDMI or DisplayPort, many industrial Panel PCs and embedded systems use LVDS to connect the internal motherboard to a built-in LCD. LVDS cables are flat and flexible, they fit neatly inside compact enclosures. The interface also supports extended temperature ranges and vibration-resistant connectors required for industrial use.

LVDS vs Other Display Interfaces

LVDS in Avalue Panel PCs

Most Avalue industrial motherboards and Panel PCs include an LVDS or eDP connector for direct panel integration. When specifying a custom Panel PC or embedded display system, confirm whether your panel requires single-channel or dual-channel LVDS, dual-channel supports higher resolutions at faster refresh rates. TSL Automation can help match the right Avalue motherboard to your display requirements.
