- FPD-Link
Flat Panel Display Link (FPD-Link) is a high-speed interface connecting the output of a
video controller in alaptop computer, computer monitor or LCD television set to thedisplay panel . Most laptops, LCD computer monitors and LCD TVs use this interface internally. (Laptops produced before around 1995 and some devices with much lower display resolutions use a TTL orCMOS voltage interfaces instead.)FPD-Link uses LVDS. It uses one
twisted pair in order to transmit a clock signal, and on the remaining wire pairs it transmits video data at a bit rate that is seven times the frequency of the clock signal.Other systems
There is another display interface which uses LVDS:
OpenLDI . It is based on FPD-Link, but allows longer cable lengths, and is a rarely used method to connect external display panels to computers. Modern stand-alone LCD display panels for desktop computers use a completely different interface such as DVI.External links
