Low-voltage Differential Signaling

Low-voltage differential signaling, or LVDS, is an electrical digital signaling standard that can run at very high speeds over inexpensive twisted-pair copper cables. It specifies the electrical-level details for interoperability between inputs and outputs on integrated circuit chips. Since it is the 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 (FPD-Link) in the video-display engineering vocabulary.

Famous quotes containing the word differential:

    But how is one to make a scientist understand that there is something unalterably deranged about differential calculus, quantum theory, or the obscene and so inanely liturgical ordeals of the precession of the equinoxes.
    Antonin Artaud (1896–1948)
