VGA, SVGA, XGA, SXGA, UXGA, WUXGA 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 is designed for typical LVDS interface TFT panels with panel voltage 3.3V or 5V or 12V LVDS interface. Due to the
variation between manufacturers of signal timing and other panel characteristics factory setup and confirmation should be obtained before
connecting to a panel. (NOTE: Check panel power jumper settings before connection)
2.
Controller card: Handle the controller card with care as static charge may damage electronic components.
3.
LVDS signal cable : In order to provide a clean signal it is recommended that LVDS signal cables are no longer than 46cm (18 inches). If loose
wire cabling is utilized these can be made into a harness with cable ties. Care should be taken when placing the cables to avoid signal
interference. Additionally it may be necessary in some systems to add ferrite cores to the cables to minimize signal noise.
4.
Inverter: This will be required for the backlight of an LCD, some LCD panels have an inverter built in. As panels may have 1 or more backlight
tubes and the power requirements for different panel models backlights may vary it is important to match the inverter in order to obtain optimum
performance. See page 15 for the Application notes “Inverter connection section for more informations.
5.
Inverter Cables: Different inverter models require different cables and different pin assignment. Make sure correct cable pin out to match the
inverter. Using wrong cable pin out may damage the inverter.
6.
OSD switch mount controls: The following section discusses the controls required and the section on connectors provides the detail. The
controls are minimal: On/Off, Backlight Brightness (depends on inverter), OSD (5 momentary buttons) analog VR type or (8 momentary buttons)
digital type.
7.
OSD switch mount controls cable: The cables to the function switches should be of suitable quality and length so that impedance does not
affect performance. Generally lengths up to 1 metre (3 feet) should be acceptable.
8.
Controller status LED (Optional) : This LED indicates the controller status. The pin direction of the LED should be corrected for right colour
indication. Red colour stands for standby. Green colours stands for signal on. The status LED is an optional part only, can be unconnected.

IR sensor: It is an optional part only, can be unconnected if not using IR remote control. See Appendix V for button definition.
10. RS-232 control interface : Firmware upgrade and serial control via this interface port.
11. HDMI input : Support HDMI 1.3 input up to 1080p/WUXGA resolution. Plug the HDMI cable to the connector J1 on
the controller board.
12. Audio output (Stereo) from HDMI : This port support Stereo audio output (no amplification) from the HDMI audio source inputted. It requires to
select the audio port “Speakers” via OSD menu under “Sound” > “Output” OSD menu page.
13. SPDIF Audio output : This port support SPDIF audio output from the HDMI audio source inputted. It requires to select the audio port “SPDIF” via
OSD menu under “Sound” > “Output” OSD menu page.
14. Power Input: 12VDC is required, this should be a regulated supply. Although the controller provides power regulation for the LCD power this
does not relate to the power supplied to the backlight inverter. If an unregulated power supply is provided to an inverter any fluctuations in power may
affect operation, performance and lifetime of the inverter and or backlight tubes.
Power Safety: Note that although only 12VDC is supplied as „power-in‟ a backlight inverter for panel backlighting produces significantly higher
voltages (the inverter does not connect to the ground plane). We strongly advise appropriate insulation for all circuitry.
EMI: Shielding will be required for passing certain regulatory emissions tests. Also the choice of external Controller to PC signal cable can affect
the result.
Ground: The various PCB mounting holes are connected to the ground plane.
Servicing: The board is not user serviceable or repairable. Warranty does not cover user error in connecting up to the controller and is
invalidated by unauthorized modification or repairs.
Page 4 of 32
Controller Mounting: It is recommended that a clearance of at least 10mm is provided above and 5mm below the controller when mounted.
Additionally consideration should be given to:
Electrical insulation.
Grounding.
EMI shielding.
Cable management. Note: It is important to keep panel signal cables apart from the inverter & backlight cables to prevent signal
interference.
Heat & Ventilation: Heat generated from other sources, for example the backlight of a very high brightness panel may generate significant
heat which could adversely affect the controller.
Other issues that may affect safety or performance.
IMPORTANT: Please read the Application Notes section for more information.

CONTROLLER DIMENSIONS
HDD-1920
The maximum thickness of the controller is 13.95mm (measured from bottom of PCB to top of components, including any underside
components & leads). We recommend clearances of:
5mm from bottom of PCB - if mounting on a metal plate we also recommend a layer of suitable insulation material is added to the
mounting plate surface.
10mm above the components
3~5mm around the edges
Any of the holes shown above can be used for mounting the PCB, they are 3.2mm in diameter.
CAUTION: Ensure adequate insulation is provided for all areas of the PCB with special attention to high voltage parts such as the
inverter.
Page 18 of 32
APPLICATION NOTES
USING THE CONTROLLER WITHOUT BUTTONS ATTACHED
This is very straightforward by following the steps below :
Firstly setup the controller/display system with the buttons. With controls attached and display system active make any settings for colour and
image position as required then switch everything off.
Use a jumper to close JP6 jumper, this will fix the board On.
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 potentially 3 issues to consider with inverter connection:
Power
Enable
Brightness
Please read the following sections for a guide to these issues.
Inverter Power: As per the table for CNB1 pin 1 is ground and pin 2 provides 12VDC. This should be matched with the inverter specification: see
table.
CNB1

DESCRIPTION

2
+12VDC
Remark: For higher power inverter, more current for 12V can be taken from CNA1 pin 1.
Maximum current drawn on CNA1 pin 1 and CNB1 pin 2 is 3A(12V)
Enable: This is a pin provided on some inverters for On/Off function and is used by this panel controller for VESA DPMS compliance. If the inverter
does not have an enable pin or the enable pin is not used then DPMS will not be operational. Pin 3 should be matched to the inverters specification
for the „enable‟ or „disable‟ pin.

Enable
Further, jumpers JB2 & JB3 should be set to match the inverters specification for the enable pin power and High or Low setting: see table.

Purpose
Inverter enable voltage
Inverter control
Note
1-2 H = 12V, 2-3 H = 5V (Vcc), OPEN H = open collector
1-2 H = On, 2-3 L = On
Brightness: There are various methods for brightness control and it is important to consider the specifications for the inverter to be used. Generally
the situation is:
Brightness can controlled by using a resistor or VR (Variable Resistor).
Brightness controlled by adding a circuit such as PWM (Pulse Width Modulation).
No adjustment of brightness is possible.
CNB1 pins 4 & 5 are available for connecting to an inverter or circuit where VR control is supported.

Page 19 of 30
Design Guideline for making VR circuitry :
Signal description / Notes :
1) R1 : 470ohm on board
2) RPOT is an external potentiometer (in-line dip
style) that can be plugged directly into CNC1 pins
3,4,5. RPOT must be supplied / installed by user.
3) BVR_B : Voltage tapped from “top” of
potentiometer, the node of R1 and RPOT.
4) BVR_WIP : Voltage tapped from wiper arm of
RPOT.
5) BVR_A : Voltage tapped from “bottom” of
RPOT.
Note : BVR_A voltage is left floating on the
controller board. To use this circuit, you need
to tie this point to a potential (usually GND,
available at CNC1 pin 6).

The VR for brightness depends on the inverter. The main power load for On/Off is handled by a relay on the controller.
Example for circuit design :
1.)Choose RPOT = 10K
2.) Tie BVR_A to GND
3.) Circuit analysis gives BVR_WIP as the
following (see Figure 1)
BVR_WIP = 5 x (Rbc/10.47)
where BVR_WIP is in Volts.
And Rbc is the resistance from the wiper arm
to bottom of pot in Kohms.
To evaluate, plug in different values of Rbc :
Rbc
0
2.5 K
5K
7.5 K
10 K
BVR_WIP
0V
1.2 V
2.4 V
3.6 V
4.8 V
So this circuit could provide Brightness adjust
voltage ranging from 0V to 5V.

TROUBLESHOOTING
General
A general guide to troubleshooting a 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, backlight tubes)
Cabling
Computer system (display settings, operating system)
Through step by step cross checking with instruction manuals and a process of elimination to isolate the problem it is usually possible to clearly
identify the problem area.
No image:
If the panel backlight is not working it may still be possible to just see some image on the display.
A lack of image is most likely to be caused by incorrect connection, lack of power, failure to provide a signal or incorrect graphic card settings.
Image appearance:
A faulty panel can have blank lines, failed sections, flickering or flashing display
Incorrect graphics card refresh rate, resolution or interlaced mode will probably cause the image to be the wrong size, to scroll, flicker badly or
possibly even no image.
Incorrect jumper settings on the controller may cause everything from total failure to incorrect image. 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 half:
Check cabling for the inverter.
For a specific backlight tube check the AC pins orientation (CAUTION: Never reverse any DC power pins).
Also:
If adjusting brightness control has no effect the chances are that the VR rating or method of adjusting brightness is not compatible or correctly
connected to the inverter.
If system does not power down when there is a loss of signal
Continued failure:
If unit after unit keeps failing consider and investigate whether you are short circuiting the equipment or doing something else seriously wrong.
Generally after common sense issues have been resolved we recommend step by step substitution of known working parts to isolate the problem.
