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.

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.
