3.1. Product Block Diagram
The LCD monitor will contain an interface board, a Power / Inverter board, and a function key board. The interface block
will house the flat panel control logic, brightness control logic, and DC-DC conversion to supply the appropriate power to
the whole board and LCD panel, and transmitting LVDS signals into LCD Module to drive the LCD display circuit. The
inverter block will drive the four dual CCFLs (Cold Cathode fluorescent Tube). The power block will provide the DC power
to interface board and LCD panel. The function key block will provides the OSD control signal, power ON/OFF and LED
indicator to the interface board.
