4. Notes for Installation
This controller is designed for RGB & DVI monitor using different size of TFT LCD panels.
This section provides some guidelines for assembly and preparation of a finished display
solution.
Preparation: Before proceeding, it is important to familiarize yourself with the parts making
up a system and the various connectors, mounting holes, and general layout of the
controller. All connectors have their own number printed on the controller board. And
their signal arrangements are shown in the following relevant sections.
LCD Panel: This controller has 12V or 5V or 3.3V LVDS interface logic on the board for
different kind of TFT LCD panel. Due to the different signal timing and electrical
characteristics from each LCD panel manufacturer, we need to use different Firmware,
different LCD interface cable and select DC power level for LCD panel even on the
same board.
For selecting DC power level, put the jumper marked JP1 on the down position.
Supplied power level, 3.3Vdc , 5Vdc and 12Vdc are marked on the board.
LCD signal cables: In order to provide a good signal, it is recommended that LCD signal
cables should be no longer than 20cm. But it depends on signal frequency and LCD
interface type.
Inverter: Each LCD panels have their own inverter to obtain optimum performance and
long lifetime. Because, Each LCD panel makers use different type of back light tubes
for their all different models and Inverter drives the tubes directly.
The controller board just supplies the power for inverter logic and controls a light On/Off
signal and a brightness control signal. So, it is important to use the inverter that has
proper driving capacity and control input signal.
Inverter cable: This cable supplies Inverter’s power, an on/off control signal and a
brightness control signal to the inverter.
OSD Button: See Operational Function section.
3 Color LED: This LED shows the state of controller.
 Green – Normal state
 Amber – Off mode (Can’t find video signals)
 Green alternates with Amber per 0.5 second – Stand by mode
 Green alternates with Amber per 1 second – Suspend mode
GREEN COLOR LED: This LED indicate what input signal source
Power switch: This switch is located on OSD button board.
Power input: +12Vdc is required to supply enough power for the controller, Inverter and
LCD panel.
VGA Input Cable: As this may affect regulatory emission test result, a suitably shielded
cable should be utilized.
Jan. 01, 2009
Page 4/15
DPADM3.1
EMI: Shielding will be required for passing certain regulatory emissions tests. Also the
choice of video board and power supply can affect the test result.
Consideration should be given to:
 Electrical insulation.
 Grounding.
 EMI shielding.
 Cable management.
 Heat & ventilation
Caution: Ensure adequate insulation is provided for all areas of the PCB with special
attention to high voltage parts such as the inverter.
*** Remarks ***
For a specific panel use, One LCD panel sample and full technical specifications for the
LCD panel from the manufacturer are required to test for tuning up screen image.
GPEG K&D can provide engineering service for customer specific controller development.
Please contact to GPEG K&D or sales representatives.

5. Setup for Operation
Once the circuit has been connected, a setup procedure for optimal operation is required
some time.
The following instructions are likely to form the basis of the finished product operation
manual.
PC Settings
The PC needs to be set to an appropriate graphics mode that has the same resolution with
the LCD panel to have clear screen image. And the vertical refresh rate should be set to one
of 56~75Hz, non-interlaced.
LCD Display System Settings
The OSD (On Screen Display) provides certain functions to have clear image and others.
This board supports 5 buttons OSD operation as a standard. The control functions defined
on OSD operation are as below.

6. Applicable Graphic and Video Mode
6.1. RGB Input format
The microprocessor measures the H-sync, V-sync and V-sync/H-sync polarity for RGB
inputs, and uses this timing information to control all of the display operation to get the
proper image on a screen.
This board can detect all VESA standard Graphic modes shown on the table below and provide more clear and
stable image on a screen.
