Revision History

January 5, 2007 – Initial release of the standard

1 Overview

1.1 Summary

This standard is provided as an adjunct to various VESA panel standards, extending those standards to embrace the VESA DisplayPort interface. Reproduced herein is Chapter 9 of the VESA DisplayPort Standard Version 1.0, which describes the DisplayPort internal connector as well as the signal and data mapping for DisplayPort when used as an LCD panel interface.

2 DisplayPort Panel Labeling Requirement

VESA Standard DisplayPort panels will use the same physical connector as VESA Standard LVDS panels (JAE FI-X30SSL-HF or equivalent). To ensure that VESA DisplayPort panels will not be accidentally connected to LVDS sources, panels conforming to this specification will prominently display a warning label or have an engraving in the chassis. Such warning labels or markings will be located as close to the panel’s DisplayPort connector as practical.

Figure 2-1: VESA DisplayPort Panel Showing Warning Label Affixed Near Connector

Figure 2-2: Example of a DisplayPort Label

3 Referencing Other VESA Standards

When referencing other VESA panel standards, please note that the panel layout illustrations in these standards are not consistent with respect to showing either all front or back views.

Therefore, care must be taken to ensure that you properly identify connector Pin 1 locations based on the call-out identifying the drawing orientation in the particular specification you are viewing.

4 DisplayPort Panel Connector

The DisplayPort internal panel connector is a 30-position, JAE FI-X-SSL or equivalent, low profile, cable-to-board, co-planar connector set. One side terminates the cable (Plug) and the other is attached to the PCB (Receptacle).

The connectors support up to four Main Link lanes (Lane 0 ~ Lane 3). In embedded connections, the cable connector assembly may support one, two, or four lanes depending on the bandwidth requirement of the application. For one-lane and two-lane Main Link configurations, the stuffing rule shall be as follows: ?When only two lanes are needed, Lane 0 and Lane 1 shall be populated while Lane 2 and Lane 3 are unpopulated.

?When only one lane is needed, Lane 0 shall be populated while Lanes 1, and 3 are unpopulated. Only the panel TCON (timing controller) side of the connector is defined in this specification. While some cables may have the same connectors on both ends of the cable-connector assembly, others may have more pins for the source side (that is, the side of graphics processor, LCD controller, etc.) for LCD backlight control, for instance.
