1920x1200 or 1920x1080(120Hz) or 1920x1080 or 1920x480 or 1680x1050 or 1600x1200 or 1600x900 or 1440x900 or
1366x768 or 1280x1024 or 1280x800 or 1280x768 or 1024x768 or 1024x600 or 800x600 or 800x480 or 640x480 resolution
TFT panels with a VGA, SVGA, WXGA, XGA, SXGA, UXGA or 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 interfaced panels with panel voltage 3.3V(4A), 5V(4A), 10v(4A)
12V(4A) or 18V(3A), External for 12V~18V interface. Due to the variation between manufacturers of 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 correct
jumper and dip switches settings to match the target LCD panel.
3.
LCD signal cable (LVDS panel)
: In order to provide a clean signal it is recommended that LVDS signal cables are no
longer than 46cm (18 inches). If those 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 cable 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 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 page 26 for more information on
connection.
5.
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 the inverter.
6.
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) or
analog VR type or (8 momentary buttons) digital type.
7.
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 meter (3 feet) should be acceptable.
8.
Status LED (LED1)
: The pin direction of the LED1 should be corrected for right color indication. Red color stands for
standby. Green colors stands for signal on. The status LED is an optional part only, can be unconnected.
9.
IR sensor
: It is an optional part only, can be unconnected if not using IR remote control. See Appendix V in details.
10. RS-232 control interface :
Firmware upgrade and serial control via this interface port.
12. Panel control signal :
Use for specific panel model.
13. SPDIF Audio output :
This port support SPDIF audio output from the HDMI / Displayport /SDI audio source inputted. The
audio output follows with the input source selected (HDMI / Displayport / SDI).
14. Ambient light sensor connection :
Support for connection using light sensor cable P/N 426305900-3 (1250mm) and
light sensor board P/N 416021310-3 via CN6 connector. See Appendix IV in details.
16. HDMI 1 input :
Support HDMI 1.4 standard.
Plug the HDMI extend cable to the connector CN5 on the controller board.
17. HDMI 2 input :
Support HDMI 1.4 standard.
Plug the HDMI extend cable to the connector CN2 on the controller board.
18. Analog RGB Input
: Plug extend VGA cable P/N 426003300-3 to the connector CNV6 on the controller board. As this may
affect regulatory emission test results and the quality of the signal to the controller a suitably shielded cable should be utilized.
19. Display Port input :
Support single-link Display Port 1.2. Plug the Display Port cable P/N 426321600-3 to the connector
CN20 on the controller board.
20. SDI Input :
3G/HD/SD-SDI signal input support. Plug the SDI extend cable to the connector J4 on the controller board
21. SDI re-clock loop out :
3G/HD/SD-SDI re-clock loop out. Plug the SDI extend cable to the connector J5 on the controller
board. Recommend to connect less than 100 meter in good co-axial cable (e.g Belden 1694A) between DV devices.
22. Power Input
: 12V/24VDC is required, this should be a regulated supply. The power rating is depending on the panel and
