2 Introduction
Thank you for buying the Display Expansion Board from Embedded Artists. The board makes it
possible for you to get started with graphical user interface development immediately. The board
directly interfaces the OEM Base Board (also from Embedded Artists) and can be mounted with it,
forming a compact unit.
2.1 Features
The features of the Display Expansion Board are:
Parallel RGB interface, 16-bit color depth (or 12-bit).
Up to 24-bit color depth supported with manual wiring.
When used together with Embedded Artists Developer’s Kits up to 16-bit color depth is
supported.
supported.
HDMI/DVI (digital) transmitter via TDA19988 from NXP
Note: limited driver functionality for this chip. CEC/HDCP functionality not implemented.
HDMI/DVI (digital) transmitter via TFP410 from TI
VGA (analog) transmitter via ADV7125KST50 from Analog Devices
LVDS (digital) transmitter via DS90C383BMT from National Semiconductor/TI
Switching between 25.175MHz, 27MHz and 36MHz pixel clocks
Spread spectrum (+-2%) oscillators used for reduced EMI. Works for digital transmitters
(HDMI/DVI/LVDS) but not for (analog) VGA.

mounted).
mounted).
Resistive touch screen controller, TSC2046 from TI (normally not used)
I2C-E2PROM with configuration parameters
Controller can read which display board that is connected and initialize the MCU LCD
controller and control the Display Expansion board accordingly.
Power control signals via I2C-GPIO
50-pos (2x25) IDC interface connector, compatible with Embedded Artists OEM base board
that is used on LPC1788/LPC3250 v2/LPC4088/LPC4357 Developer’s Kits
Proper ESD protection on HDMI, DVI and VGA ports
Powered via interface connector
3.3V and 5V required
Compact size: 165 x 150 mm
Simple mounting together with OEM Base Board
2.2 ESD Precaution
Please note that the Display Expansion Board comes without any case/box and
all components are exposed for finger touches – and therefore extra attention
