ASSEMBLY NOTES
This controller is designed for monitor and other flat panel display applications using 1280x1024,
1024×768, 800×600, and 640×480 resolution TFT panels with a VGA, SVGA, XGA or 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. Guides to
connectors and mounting holes are shown in the following relevant sections.
1. LCD Panel:
This controller is for TFT panels with 3.3V, 5V, 12V TTL or LVDS interface. 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.
Make sure the relevant connection and operation to match the target LCD panel.
3. LCD connector Board:
Different makes 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 be not longer than about 30
㎜
. Care should be taken when placing the cables to avoid
signal interference.
5. Inverter:
This will be required for the backlight of an LCD; some LCD panels have an inverter
built in. As LCD panels may have one 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 Cables:
Different inverter models require different cables and different pin assignment.
Make sure correct cable pin out to match inverter. Using wrong cable pin out may damage to
inverter.
7. OSD Controls:
The following section discusses the controls required and the section on
connectors provides the detail. The controls are minimal: OSD (7 momentary buttons) digital type.
8. OSD 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 meter should be
acceptable.
9. VGA Input Cable:
As this may affect the quality of the signal to the controller a suitably shielded
jack should be utilized.
10. Composite Video Cable:
It’s Composite video jack. Reasonable quality cable should be used
to avoid image quality degradation.
S-Video Cable:
It’s for S-Video signal.
11. TV tuner & cable:
It’s for TV/FM. For TV/FM TV tuner add-on board is required. There are
three types of video format: PAL, NTSC & SECAM.
