<P>PROBLEM TO BE SOLVED: To provide a display controller enabling information display by a plurality of display devices in a state having high versatility while suppressing increase of the number of components as much as possible. <P>SOLUTION: An output end of a power source circuit 10 is connected to a first end and a first connection terminal 31 of a switch circuit 17, a driving end of an LED driver circuit 18 is connected to a second connection terminal t2 and a third connection terminal t3, and a second end of the switch circuit 17 is connected to a fourth connection terminal t4 and a fifth connection terminal t5. The power source circuit 10 can output a first voltage V1 higher than a first minimum voltage Vm1 required for conduction of a first LED circuit 21, a second voltage V2 lower than the first minimum voltage Vm1 and higher than a second minimum voltage Vm2 required for conduction of a second LED circuit 22, and a third voltage V3 lower than the first minimum voltage Vm1 and higher than a third minimum voltage Vm3 required for driving of an organic EL driver circuit 14. <P>COPYRIGHT: (C)2011,JPO&INPIT |
