Power board (include: AC/DC,inverter) - 15 - Monitor Block Diagram The LCD monitor will provide thr 12V DC-power to inverter/ power board. The Adapter will contain an main board, an inverter/ power board, key board and internal adapter which house the flat panel control logic, brightness control logic and DDC. The inverter board will drive the backlight of panel and the DC-DC conversion.
