CN2 Pin 1 CN1 VEE AR-B9413 Transfer Boad LCD Panel AR-B9413 Transfer Card Inverter & Contrast CN3 VBL Control +12V On-Board VGA Card Inverter Board FL HIGH Voltage The block diagram shows that AR-B9413 still need components to be used for LCD panel. The inverter board provides the control for the brightness of the LCD panel while the inverter is the one that supplies the high voltage to drive the LCD panel. Each item will be explained further in the section. Page 5 NOTE : Be careful with the pin orientation when installing connectors and the cables. A wrong connection can easily destroy your LCD panel. The pin 1 of the cable connectors is indicated with a sticker and the pin1 of the ribbon cable is usually with different color. The inverter board is the one that supplies the high voltage signals to drive the LCD panel by converting the 12 volt signal from the AR-B9413x into high voltage AC signal for LCD panel. It can be installed freely on the space provided over the VR board, if the VR board is installed on the bracket, you will have to provide a place to install the inverter board into your system. 3.2.
