This controller is designed for monitor and custom display projects using 1280x1024, 1024x768, 800x600, 640x480 resolution
TFT LVDS LCD’s support. The following provides some guidelines for installation and preparation of finished display solution.
ASSEMBLY NOTES
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. As much as possible connectors have been labeled.
Guides to connectors and mounting holes are shown in the following relevant sections.
LCD Panel: This controller is designed for typical LVDS interface TFT panels with panel voltage 3.3V or 5V or 12V,
External for 12V~18V 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)
Controller card: Handle the controller card with care as static charge may damage electronic components.
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.
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 13 for the Application notes “Inverter connection
section for more informations.
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.
Function Controls: The following section ‘Operation’ discusses the controls required and the section ‘Connectors,
jumpers & pinouts’ provides the detail. The controls are minimal for ease of use: On/Off, Brightness (depends on inverter),
OSD (5 momentary buttons).
Function 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.
Status LED: The pin direction of the LED should be corrected for right colour indication. Red colour stands for standby.
Green colour stands for signal on. It is an optional part only, can be unconnected.
Analog VGA Input Cable: As this may affect regulatory emission test results and the quality of the signal to the controller,
a suitably shielded cable should be utilized.
Power Input: 12V DC 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 and power supply can affect the result.
Ground: The various PCB mounting holes are connected to the ground plane.
Servicing: The controller 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.
