Low-voltage differential signaling(LVDS),also known as TIA/EIA-644,is a technical standard that specifies electrical characteristics of a differential,serial communications protocol. LVDS operates at low power and can run at very high speeds using inexpensive twisted-pair copper cables.
Since LVDS is a physical layer specification only,many data communication standards and applications use it but then add a data link layer as defined in the OSI model on top of it.LVDS was introduced in 1994,and has become popular in products such as LCD-TVs, automotive infotainment systems,industrial cameras and machine vision,notebook and tablet computers,and communications systems.The typical applications are high-speed video,graphics,video camera data transfers,and general purpose computer buses.Early on,the notebook and LCD display vendors commonly used the term LVDS instead of FPD-Link when referring to their application,and the term LVDS has mistakenly become synonymous with Flat Panel Display Link in the video-display engineering vocabulary.
