FPD-Link - FPD-Link and LVDS

FPD-Link and LVDS

FPD-Link was the first large-scale application of the LVDS standard. National Semiconductor immediately provided interoperability specifications for the FPD-Link technology in order to promote it as a free and open standard, and thus other IC suppliers were able to copy it. FlatLink by TI was the first interoperable version of FPD-Link.

By the end of the twentieth century, the major notebook computer manufacturers created the Standard Panels Working Group (SPWG) and made FPD-Link/FlatLink the standard for transferring graphics and video through the notebook's hinge. Since it was the first successful use of LVDS, to this day many display engineers use the generic term LVDS when they actually mean FPD-Link/FlatLink product technology.

There have been numerous attempts to displace the SPWG and FPD-Link as the standard internal video interface in mobile devices and LCD TVs. For example, VESA designed Embedded and Internal DisplayPort with the intention to replace LVDS (when they really mean FPD-Link) as an internal interface. Embedded DisplayPort has some success in notebook computers, but Internal DisplayPort has limited use inside LCD TVs. The reason for FPD-Link's resilience is its simplicity and the low cost eco-system (PCB, power supply, firmware, etc.) needed for implementation.
