1 Introduction
1.1 Overview
The Flat Panel Transfer Board (FPTB) is intended for prototyping and verification of LVDS
and TTL flat panel displays with COM Express systems. The FPTB is equipped with an
LVDS-to-TTL converter to allow users to implement TTL displays with COM Express systems
that support LVDS only. Onboard PWM circuitry supports backlight control for LVDS and TTL
displays.

1.4 Applications
The FPTB is intended for use in the following situations:
•nanoX/Express-BASE →FPTB →Customer’s cable to TTL display: This
configuration provides LVDS-to-TTL conversion and backlight control when using an
ADLINK reference carrier board with a TTL display. User must provide the cable
connection from the FPTB's TTL output and backlight control connectors to the TTL panel
inputs.

LVDS panel: This configuration provides backlight control and convenient verification of
LVDS function when using a customer carrier board with the HannStar 10.1” LVDS flat
panel display. User must provide the cable connection from the customer carrier board
LVDS output to the FPTB's LVDS input connector.
