LVDS stands for low-voltage differential signalling and is a method for driving an open frame LCD panel directly from an embedded motherboard. There are two main types, single channel which supports small screens at low to medium resolutions (usually up to 1280×1024) and dual channel which supports larger displays running at higher resolutions. LVDS allows for compact embedded system designs as there is no requirement to use bulky video cables and connectors. To use an LVDS screen, custom cable assemblies are almost always required. LVDS is used instead of the standard methods for connecting a screen, such as VGA, DVI or HDMI.
