LCD signal cable (use for LVDS panel) 4. Inverter for backlight (if not built into LCD) 5. Inverter cable 6. Function controls 7. Function controls cable 8. Status LED (optional) 9. IR sensor (optional) 10. RS-232 control interface 11. Second RS-232 control interface 12. External panel power output 13. Panel control signal 14.
ASSEMBLY NOTES This controller is designed for monitor and custom display projects using 1920x1200 or 1920x1080 or 1600x1200 or 1680x1050 or 1440x900 or 1366x768 or 1280 x 1024 or 1024 x 768 or 800x600 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.
11. Second RS-232 control interface : This interface support controlled under “Programming mode” . Press and hold “MENU” button on the OSD switch mount and turn on the controller to enter the “Programming mode”. Choose “Set Uart 1 Input Port” shown below : . Set “Uart 1 to IP-50 : Enable Ethernet network (J1) support and disable second RS-232 serial control (CN1) support Set “Uart 1 to CN1 : Enable second RS-232 serial control (CN1) support. Disable Ethernet network (J1) support 12.
inverter used. Normally, power supply with 3.5Amp current output should enough for most of 4x CCFT panels. 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. 29.
CONNECTION & OPERATION CAUTION: Never connect or disconnect parts of the display system when the system is powered up as this may cause serious damage. CONNECTION Connection and usage is quite straight forward (it is useful to have the relevant connection diagram available at this time): 1. LCD panel & Inverter: Connect the inverter (if it is not built-in the panel) to the CCFT lead connector of the LCD panel. 2. LVDS type panels: The controller board has the built-in LVDS transmitter driver.
LCD DISPLAY SYSTEM SETTINGS NOTE: By way of explanation the following refers to a set of sample buttons that may be obtained as an option.

Please go to download at http://www.digitalview.com/products/sgx-1920-lcd-controller The maximum thickness of the controller is 17.67mm with or without video add-on board (measured from bottom of PCB to top of components, including any underside components & leads).
APPLICATION NOTES USING THE CONTROLLER WITHOUT BUTTONS ATTACHED This is very straightforward: • Firstly setup the controller/display system with the buttons. With controls attached and display system active make any settings for colour, tint and image position as required then switch everything off. • Remove the control switches, the 12-way (CNC1) cable. • Use a jumper or similar to connect pins 1 & 2 on CNC1, this will fix the board On.
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.
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 t

Appendix IV – Auto Color Gain The Auto Color Gain function is supported in the ARGB mode only and is designed to calibrate the controller to the incoming video signal. In order to calibrate correctly, the display must be displaying an image containing both black and white data (see illustration below) when the function is used. The internal processor of the video controller chip will then execute a process to adjust the relative values of the RGB signals to achieve the best performance.

Appendix VI – Function description for de-interlacing mode AFM, TNR, MADI, DCDi AFM = Auto Film Mode : It is a frame based method which used for the input ODD and EVEN fields have a fixed relation between each other, such as static image, 3:2 pull down mode. If two fields are correctly merged, it can get the best quality. But if it merges two wrong fields, it will have artifact and get the worst quality.
Appendix VIII – Network connection The SGX-1920 LCD interface controller has an RJ-45 Ethernet port for control and monitoring over a network. This application note introduces the two user interface modes: • • Browser based web server mode Command line direct mode (this is the default mode) There is also a short overview of the command set and how it is implemented.
