CHARACTERISTICS ADJUSTMENT METHOD OF ELECTRON SOURCE AND MANUFACTURING METHOD OF ELECTRON SOURCE, AND CHARACTERISTICS ADJUSTMENT METHOD AND MANUFACTURING METHOD OF IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce variation of the electron emission characteristics of the electron emitting element and display characteristics of the display element easily and in a short time and improve the image quality.;SOLUTION: The emitting current of the surface conducting emitting element at the time of pressing of drive current is measured (S1-4), and by performing a one-dimensional or two-dimensional filter treatment to the measured value, characteristics objective values are established (S8-9). By impressing a characteristics shift voltage having a voltage or an impressing time that corresponds to the initial characteristics of each element, the characteristics is shifted so that the electron emission characteristics may realize the characteristics objective values.;COPYRIGHT: (C)2003,JPO
