Flat Panel Display Interface -2
Version: 1
February 14, 1998
Purpose<=
/span>
The purpose of this standard is to define=
an
electrical, logical, and connector interface for flat panel displays. The usage is within closed environ=
ments,
typically notebook computers or monitor enclosures.
Summary<=
/span>
Earlier standards, FPDI-1 and FPDI-1B, we=
re
compilations of existing flat panel display specifications in production at
that time. FPDI-2 defines a c=
ommon
interface that is display technology independent and scalable through HDTV
addressabilities. The goal is=
to
reduce flat panel display manufacturers design costs, system integration co=
sts,
and time to market.

1 The term LVDS is used in this docu= ment as a generic term and does not imply any particular LVDS technology.
2 The term TMDS, a trademark of Sili= con Image, Inc., will generally be used in this document to denote PanelLinkä or compatible technologies.
This standard describes the electrical, logical, and c=
onnector
interface for a flat panel display.
The FPD with its standardized interface will be used in mobile
computers, desktop monitors, or in embedded industrial applications. The electrical signal layer is
The envisioned usage for a compliant FPD is in closed systems, typically notebook computers or desktop monitors. The connector is rated as an inter= nal connector. The electrical and logical interface can extend outside the closed environment. An optional monitor bulkhead conne= ctor interface is described in the VESA P&D standard.
The VESA P&D standard defines the video port for t= he host system using TMDS. The F= PDI-2 standard is fully compatible with and is an extension of that standard as t= he receiver of the video data. T= he dual use FPDI-2 display provides for the following:
· Compatibility with video graphics controllers using integrated TMDS transmitters,
· Reduction of the number of software device drivers that need to be written,
· Reduction of the system integrator’s display inventory,
·
· Enables FPD manufacturers to produce a common panel interface regardless of size and resolution requirements.
Sev= eral standards are referenced by this document and should be considered a part of the FPDI-2 specification.
