ASSEMBLY NOTES
This controller is designed for monitors and custom display projects using 1280x1024, resolution TFT LCD
panels with a VGA, SVGA, XGA, SXGA signal input. The following provides some guidelines for installation
and preparation of a finished display solution.
Preparation: Before proceeding it is important to familiarize yourself with the parts making up the system
and the various connectors, mounting holes and general layout of the controller. As much as possible
connectors have been labeled. Guides to connectors and mounting holes are shown in the following relevant
sections.
1. LCD Panel: This controller has 5V, 3.3V or 12V LVDS interface logic on the Board for different kind of TFT
LCD panel. For the other type of LCD interface like Panel Link interface and etc, this board can accommodate
a daughter board instead of on-board LCD interface. Due to the different signal timing and electrical
characteristics from each LCD panel manufacturer, for selecting LCD interface type and resolution, put
jumper marked J4 on the right position following LCD panel specification. For selecting DC power level, put
jumper marked J12 on the right position. Supplied power level depends on LCD panel specification.
2. Controller: Handle the controller with care as static charge may damage electronic components, Make
sure correct jumper and switches settings to match the target LCD panel
3. LCD connector board: Different makers and models of LCD panel require different panel signal
connectors and different pin assignments.
4. LCD signal cables: In order provide a clean signal it is recommended that LCD signal cables should not
longer than 30cm. If loose wire cabling is utilized these can be a made into a harness with cable ties. Care
should be taken when you place the cables to avoid signal interface. Additionally it may necessary in some
systems to add ferrite cores to the cables to minimize signal noise.
5. Inverter: This will be required for the backlight of an LCD, some LCD panel have an inverter built in. As
LCD panels may have 1 or more backlight tubes and the power requirements for different panel backlights
may vary it is important to match the inverter in order to obtain optimum performance. See application
notes for more information on connection.
6. Inverter cable: Different inverter models require different cables and different pin assignment. Make sure
the correct cable pin out to match the inverter. Unsuitable cable pins out may damage the inverter.
7. OSD Button:See Operational Function section.
8. 3 Color LED:This LED shows the state of controller.
Green – Normal state
Off – Off mode (Can’t find Sync. signals)
Amber – DPMS mode
9. Power switch:This switch is located on OSD button board.
10. Power input: +12VDC is required to supply power for the controller, the Inverter and the LCD panel
11. VGA Input Cable: As this may affect regulatory emission test result, a suitably shielded cable should
be utilized.

Data Sheet NCB210X2
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.
Heat & ventilation
Caution:Ensure that the 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. KORDIS can provide engineering service
for customers specific controller development.
12. Setup for operation
Once the circuit has been connected, a setup procedure for optimal is requires a few minutes 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
signal.
LCD display System Settings
The OSD (On Screen Display) provides certain functions to have clear image and others. This board
supports 4 buttons OSD operation as a standard. The control functions defined on OSD operation are as
below.
Pc Graphics Output: A few guidelines:
Signal quality is very important, if there is noise or instability in the PC graphics output this may
result in visible noise on the display
Refer to the graphic modes table in specification section for supported modes.
Non-interlaced & interlaced video input is acceptable.
Important: please read the application notes section for more information.
