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.
