DRIVING METHOD AND DEVICE FOR ELECTRON SOURCE, AND PICTURE FORMING DEVICE USING THE ELECTRON SOURCE

摘要

PROBLEM TO BE SOLVED: To operate a device stably for a long time by suppressing variation of a characteristic of plural electron emitting elements owned by an electron source. SOLUTION: This device is a driving device of a display panel 1000 provided with an electron source having plural electron emitting elements. In this case, a modulated signal outputted from a modulation signal generator 87 is passed through band filters Fy1-Fyn based on a picture signal of one line stored in a line memory 85, and a resonant frequency component in an electron source is eliminated. Thus, a driving signal from which a resonant frequency component is eliminated is inputted to column wiring terminals Dy1-Dyn of the display panel 1000, the display panel 1000 is driven synchronizing with a scan signal inputted to row wiring terminals Dx1-Dxm of the same display panel 1000, and a picture is displayed. Thereby, the display panel 1000 can be displayed and driven preventing resonance in an electron source which causes deterioration of an electron emitting characteristic of an electron emitting element.
