Abstract: <P>PROBLEM TO BE SOLVED: To reduce power consumption when a bright video is displayed on an FED panel without decreasing the number of gradations for a video signal.  <P>SOLUTION: A comparator 4 compares the voltage drop of a resistor 2 which gives an anode current value with a reference set voltage. When the control signal of the comparator 4 gives a relation of the voltage drop > the reference set voltage, a driving circuit power source 6 reduces its output voltage V<SB>DD</SB>from an initial value V<SB>DD0</SB>according to the difference value until the voltage drop becomes equal to the reference set voltage. As a result, a gate driving circuit 5A reduces a scan pulse V<SB>SCAN</SB>voltage generated in accordance with a timing signal by a reduced portion of the driving circuit power source voltage. A cathode driving circuit 5B generates/outputs a data pulse V<SB>DATA</SB>that is pulse-width-modulated or amplitude-modulated according to the gradations of video data.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
