ASSEMBLY NOTES

This controller is designed for monitor and custom display projects using 1024 x 768
resolution TFT panels with a VGA, SVGA or 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 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 for TFT panels with 5V or 3.3V TTL or LVDS interface.
For LVDS a separate add-on board is required. Due to the variation between
manufacturers panels 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: Handle the controller with care as static charge may damage electronic
components.
•
3. LCD signal cables: In order to provide a clean signal it is recommended that LCD
signal cables are no longer than 33cm (13 inches). If loose wire cabling is utilised 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 minimise signal noise.
•
4. LCD connector: Different makes and models of LCD panel require different panel
signal connectors and different pin assignments.
WIRING NOTE
panel signal high value should correspond to the controllers highest bit. For example for
a 6 bit panel R5 on the panel should connect to R7 on the controller, in this case R1 &
R0 on the controller will not be connected.
•
5. 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 backlights may vary it is important to match the inverter
in order to obtain optimum performance. See Application notes for more information on
connection.
•
7. Inverter to Backlight Cables: (Not so relevant if the inverter is built into the LCD
panel module). These are high tension and thus prone to power leakage. Suitable cable
should be selected of minimum length, additionally care should be taken when laying out
this cable.
•
8. Function 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).
9. 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.
