Abstract

PURPOSE: To attain a display driving control having necessary luminance even for an element requiring power more than the capacity of one driving terminal by outputting required driving power from respective driving terminals connected to one display electrode in common. CONSTITUTION: A CPU 3 in a microcomputer unit 2 connects common electrodes and segment electrodes in a multi-digit fluoresent device to common driving terminals Ccom1 to Ccom32 and Cseg1 to Cseg7 in accordance with specification through a common driving terminal connection state specifying regitster 12 and a control register 13 in a display controller 1. A common driver 6 is controlled by a display control circuit 11 provided with a control logic part, a counter, a common data forming circuit, etc., synchronous driving power is outputted from the common driving terminals Ccom1, Ccom2, or the like and an element requiring power supplied to a common terminal connected to these terminals Ccom1, Ccom2 or the like in common and more than the capacity of one driving terminal is driven and required luminance display can be attained.
