The terminals for a display content control signal or product specification control signal output by an integrated circuit for detecting a display format of a display panel are all connected to a corresponding drive pattern of a circuit board used for conveying drive signals to the display panel through a connector, so that a plurality of different types of displays may be driven without requiring different dedicated electronic circuits modified for each type of display. A plurality of different display panels each having a unique display format are prepared for use in different destinations, and the drive pattern on the display panel indicates the destination, thereby making possible to provide a display content switch section or product specification switch section within the display panel.
