OpenLDI
Encyclopedia
OpenLDI is a high-bandwidth digital interface standard for connecting flat panel LCD
monitors to computers. While it is virtually unknown in standalone displays, it has a strong basis in the interconnect for internal displays, as in laptops. OpenLDI is based on the de-facto FPD-Link
specification and uses LVDS signalling. The standard was promoted by National Semiconductor
, Texas Instruments
, Silicon Graphics
and others. OpenLDI largely faded from view with the rise of 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.
