Patent ID: 6847337

Claim:
An electron source driving apparatus for an electron source where a plurality of electron-emitting devices are connected to a plurality of scanning lines and a plurality of signal lines crossing the plurality of scanning lines, comprising: a scanning means for performing, for all of the plurality of scanning lines in succession, an operation including selection of a desired scanning line out of the plurality of scanning lines, application of a selection signal to the selected scanning line, and application of a non-selection signal to each unselected scanning line; and a signal line driving means for dividing the plurality of signal lines into a plurality of groups and applying a selection signal to the plurality of signal lines so that timings, at which the application of the selection signal to respective groups is started, are shifted from each other, wherein if an electric capacity of the scanning lines is referred to as C and electric resistance of the scanning lines is referred to as R, a time difference that is equal to or more than a value obtained by a multiplication of CR by 0.9 is maintained between the timings at which the application of the selection signal to respective groups is started.
