ELECTRON SOURCE AND DRIVING METHOD OF IMAGE FORMING DEVICE USING THE SAME

摘要

PURPOSE:To provide the driving method of the image forming device capable of making a stable image display with small luminance variation and small color variation. CONSTITUTION:The image forming device is equipped with the electron source, constituted by wiring electron emission elements 8 having voltage controlled negative resistance characteristics in simple matrix and a fluorescent body 88 and this driving method applies half-selected elements with a voltage which is higher than a higher voltage and lower than the electron emission threshold voltage of the electron emission elements between two voltages which flow an element current a half as high as the maximum element current of current- voltage static characteristics of the electron emission elements 84.
