Introduction Designed for LCD monitor and other flat panel display applications, the AVP-1600 controller is an easy to use interface controller for: ¾ ¾ ¾ ¾ ¾ ¾ ¾ Composite and S-Video input of PAL, NTSC, SECAM video sources. Jumper selectable for two S-Video & two composite video or four composite video input. TFT (active matrix) LCDs with LVDS / TTL single pixel interface LCD resolutions from 1600x1200 to 640x480.
SYSTEM DESIGN A typical LCD based display system utilizing this controller is likely to comprise the following: Summary: 1. LCD panel 2. LCD controller card, AVP-1600 3. LVDS cable (for connection with LVDS panel) 4. TTL cable (for connection with TTL panel) 5. Inverter for CCFT backlight (if not built into LCD) 6. Inverter cable 7. Function controls 8. Function controls cable 9. Status LED (Optional) 10. IR sensor (Optional) 11. Audio add-on board (optional) 12. RS-232 control interface 13.
ASSEMBLY NOTES This controller is designed for monitor and custom projects with PAL, NTSC, SECAM video sources over Composite or S-Video using 1600x1200 or 1400x1050 or 1366x768 or 1280x1024 or 1280x800 or 1280x768 x 1024x768 or 800x600 or 800x480 or 640x480 resolution TFT type LCD panels display with TTL or LVDS inputs. The following provides some guidelines for installation and preparation of a finished display solution.
9. Controller status LED (Optional) : This LED indicates the controller status. The pin direction of the LED 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. Controller LED status (LED1) : State LED color No signal & backlight off RED No signal & backlight on ORANGE With signal & backlight on GREEN 10.
• • • • • • Electrical insulation. Grounding. EMI shielding. Cable management. Note: It is important to keep panel signal cables apart from the inverter & backlight cables to prevent signal interference. Heat & Ventilation: Heat generated from other sources, for example the backlight of a very high brightness panel may generate significant heat which could adversely affect the controller. Other issues that may affect safety or performance.
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: Plug the LVDS signal cable direct to CN1 (if necessary).
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.

CONTROLLER DIMENSIONS The maximum thickness of the controller is 17.6mm (measured from bottom of PCB to top of components, including any underside components & leads). We recommend clearances of: • 5mm from bottom of PCB - if mounting on a metal plate we also recommend a layer of suitable insulation material is added to the mounting plate surface. • 10mm above the components • 3~5mm around the edges Any of the holes shown above can be used for mounting the PCB, they are 3.2mm in diameter.
APPLICATION NOTES USING THE CONTROLLER WITHOUT BUTTONS ATTACHED This is very straightforward by following the steps below : • Firstly setup the controller/display system with the buttons. With controls attached and display system active make any settings for color and image position as required then switch everything off. • Use a jumper to close JP6 jumper, 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: ¾ Controller (jumpers) ¾ Panel ¾ Backlight (inverter, cabling, backlight tubes) ¾ Cabling ¾ Video Source 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 the problem area.
