Picture image display apparatus
摘要:
The picture image display apparatus in accordance with the present invention comprises:a flat type vacuum enclosure having a transparent face panel,an electron beam emitter which emits a predetermined number of electron beams disposed in a row in selected positions,a row of control electrodes to control intensities of said electron beams,a row of parallel deflection electrodes, every other one of them being first electrodes commonly connected each other, the other ones of them being second electrodes commonly connected to each other,a phosphor screen formed on the inner face of said face panel and,an anode of thin metal film formed on said surface of said phosphor screen,wherein the apparatus is characterized in thatevery gap defined by one of said first electrodes and one of said second electrode neighboring thereto form deflection electric fields of opposite directions to each other, and said gaps are disposed in a manner that said electron beams simultaneously pass through every said deflection gap.
