发明名称 ELECTRON SOURCE, IMAGE FORMATION DEVICE USING IT AND THEIR MANUFACTURE
摘要 <p>PURPOSE: To uniform the electric characteristics of surface conduction type electron emitting elements so as to facilitate control, and facilitate brightness adjustment and the like by applying a correcting waveform different from the waveform at an element driving time to at least one of the electron emitting elements in advance. CONSTITUTION: The electron emitting characteristics of respective surface conduction type electron emitting elements are measured in a correction process. For instance, paying attention to the electron emitting characteristic of one piece of the surface conduction type electron emitting elements, the correcting voltage of a larger waveform than the waveforms of the applied voltages in respective manufacturing processes and a driving voltage, to be concrete, the correcting waveform with a larger crest value than the maximum crest value of the driving waveform and/or the correcting waveform with a wider pulse width than the maximum pulse width the other surface conduction type electron emitting elements whose electron emitting characteristics deviate from that of the attention-paid surface conduction type electron emitting element. Thereby, the electron emitting characteristics of the respective surface conduction type electron emitting elements become uniform so that correction and the like at the driving time required before can not be required.</p>
