ABSTRACT:
In a system of this invention, either a first type flat panel display unit or a second type flat panel display unit which is different in type from the first type flat panel display unit can be selectively, mechanically, and electrically connected and disconnected to and from a base unit. The base unit includes a power supply for applying a reference voltage, and applies the reference voltage to a display unit which is mechanically and electrically connected therto. The first type flat panel display unit is driven by the reference voltage. The second type flat panel display unit includes a voltage converter, and is driven by a voltage converted from the reference voltage. With the above arrangement, the system can use a plurality of flat panel display units with one base unit.
