ASSEMBLY NOTES
This controller is designed for monitors and custom display project using 1024x768, resolution TFT
LCD panels with a VGA, SVGA, XGA 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 the various connectors, mounting holes and general layout of the controller. As many 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 12V, 5V or 3.3V TTL interface and 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 J14 on the right position following LCD panel specification. For selecting DC power level, put jumper marked J17 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 to provide a clean signal it is recommended that LCD signal cables should not be longer than 30cm. If loose wire cabling is utilized these can be a made into a harness with cable ties. You should take care when placing 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 has an inverter in it.
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 video signals)
Amber – DPMS mode

Kordis Media Co.,ltd.
Data Sheet
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.
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.
12. Setup for operation
Once the circuit has been connected, a setup procedure for optimal 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, but 6 - button operation can be supported with a different firmware if it is required. 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 specifications section for supported modes.
Non-interlaced & interlaced video input is acceptable.
Important: please read the application notes section for more information.

CAUTION: Never connect or disconnect parts of the display system when the system is powered up as this may cause serious damage.
CONNECTION
1. LCD panel & inverter: Connect the inverter (if it is not built- in the panel) to the CCFT lead connector of the LCD panel.
2. TTL type panels: Plug the signal cable direct to J4 (for Single 6bits, or Single (Dual first) higher 6bit, J6 (8bit dual (J6) and 8bits single lower 2bit) on the controller board. Plug the other end of cables to the LCD connector board (if connector board is required, otherwise the signal can be directly plugged to the LCD panel connector).
LVDS type panels: Plug the signal cables direct to J10 on the controller board. Plug the other end of cable to the LCD connector board (if connector board is required, otherwise the signal can be direct plug to the LCD panel connector).
3. Inverter & Controller: Plug the inverter cable to J8 on the controller board and the other end to the connector on the inverter.
4. Function switch & Controller: Plug the OSD switch mount cable to J2 on the controller board and another end to the OSD board.
5. Jumpers & Switch: Check all jumpers {J19 (External power Setting), J17 (Target panel power is set)} and switches (J14, Target panel selection) are set correctly. Details about the jumpers and switches setting table are in the following section
6. VGA cable & Controller: Plug the VGA cable to the connector J3 on the controller board.
7. Power supply & Controller: Plug the DC 12V power in to the connector J7.
8. Power on: Switch on the controller board and panel by using the OSD switch mount.
General:
If you use supplied cables & accessories, ensure that they are correct for the model of the panel and the controller.
If you make your own cables & connectors refer carefully to both the panel & inverter specifications and the section in this manual, “Connectors, Pin outs & Jumpers” to ensure the correct pin to pin wiring.
PC SETTING
The controller has been designed to take a very wide range of input signals however to optimize the PC’s graphics performance. We recommend you to choose 60Hz vertical refresh rate – this will not cause screen flicker.

APPLICATION NOTES
USING THE CONTROLLER WITHOUT THE ATTACHED BOTTONS
This is very straightforward:
First, set up the controller/display system with the buttons. With the attached controller and display system active make any settings for color, contrast and image position as required then switch everything off.
Remove the control switches, the 7-way (J2) cable.
Refer to inverter specifications for details as to fixing brightness to a desired level, this may require a resistor, an open circuit or closed circuit depending on inverter
INVERTER CONNECTION
There are 3 potentially issues to consider with the inverter connection:
Power
ON/OFF
Brightness (DIM-ADJ)
Inverter power: This should be matched with the inverter specification.
Inverter ON/OFF: This is a pin provided on some inverter for ON/OFF function and is used by this panel controller for VESA DPMS compliance. If the inverter does not have on/off pin or the on/off pin is not used DPMS will not operate. Pin 5 should be matched to the inverter specification for the
ON/OFF pin.
Brightness Dimming control: NCB100 controller boards are analog dimming control method.
And it is important to consider the specifications for the inverter to be used.

TROUBLESHOOTING
General
A general guide to troubleshooting of flat panel display system it is worth considering the system as separate elements, such as:
Controller (jumpers, PC settings)
Panel (controller, cabling, connection, panel, PC settings)
Backlight (inverter, cabling, connection, panel, Pc settings)
Cabling
Computer system (display settings, operating system)
Through checking the system step by step, to identify the problem are a clearly.
No image:
If the panel backlight is not working it may still be possible to just see some image.
A lack of image is most likely to be caused by an incorrect connection, lack of power, failure to provide a signal or incorrect graphic card settings.
Image position:
If it is impossible to position the image correctly, in the image adjustment controls will not move the image far enough, then test using another graphics card. This situation can occur when a graphic card is not close to timing or when something is in the graphics line that may affect the signal such as a signal splitter (please note that normally a signal splitter will not have any adverse effect).
Image appearance:
A faulty panel can have blank lines, failed sections, flickering or flashing display.
Incorrect graphic card refresh rate, resolution or interlaced mode will probably cause the image to bigger or smaller, to scroll, to flicker badly or to have even no images.
incorrect jumper settings on the controller may cause everything from incorrect image viewing to total failure.
CAUTION: Do not set the panel power input incorrectly.
Sparkling on the display: faulty panel signal cable.
Backlight:
Items to check include: Power input, controls, inverter and Tubes generally in this order.
If half the screen is dimmer than the other :
Check cabling for the inverter.
Also:
If system does not power down when there is a loss of signal.
