Open LDI

OpenLDI is a high-bandwidth digital-video interface standard for connecting graphics/video processors to flat panel LCD monitors. Even though the promoter’s group originally designed it for the desktop computer to monitor application, the majority of applications today are industrial display connections. For example, displays in medical imaging, machine vision, and construction equipment use the OpenLDI chipsets.

OpenLDI is based on the FPD-Link specification, which has been the de facto standard for transferring graphics and video data through notebook computer hinges since the late 1990s. Both OpenLDI and FPD-Link use LVDS as the physical layer signaling, and the three terms have mistakenly been used synonymously.

The OpenLDI standard was promoted by National Semiconductor, Texas Instruments, Silicon Graphics and others. OpenLDI did not get used in many of the intended applications after losing the computer-to-monitor interconnect application to a competing standard, DVI.

The Silicon Graphics 1600SW is the only monitor produced in significant quantities which uses the OpenLDI connection, though minor differences exist between the 1600SW's implementation and the final published standards. The 1600SW uses a 36-pin MDR36 male connector.

Sony produced some VAIO displays and laptops using the standard.
