The generation means which generate the voltage for Drive mannered null multiple graduation displays

摘要

PROBLEM TO BE SOLVED: To provide a drive circuit for a display device and a drive method therefor realizing a reduction in power consumption.;SOLUTION: An operational amplifier 1015 for generating a plurality of gradation display voltages is arranged. A switch 6 is arranged for selecting a gradation display voltage from among the plurality of gradation display voltages according to display data and outputting it. A control circuit 5 is arranged for detecting which gradation display voltage each output from the switch 6 selects and outputs among the plurality of gradation display voltages and controlling the operational amplifier 1015.;COPYRIGHT: (C)2004,JPO
