DISPLAY DEVICE AND ELECTRON BEAM APPLIED EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To prolong operation lifetimes of a display device using thin film type electron sources arranged in a matrix shape and electron beam applied equipment.

SOLUTION: A pulse having the opposite polarity from a scanning pulse is applied to a scanning line or a pulse having the opposite polarity from data pulses is applied to a data line to invert the polarity of a voltage applied to a thin film type electron source at lest once in a 1-field period.
