Method and device using electron beam to scan for matrix panel display
 A new scanning method and device for matrix panel display for using electron beam to scan comprising the steps: connecting each anode of dc matrix display panel to the display supply's anode via a switch cell whose status is controlled by electron beam, using one electron beam to irradiate to some anode; using another electron beam to irradiate to some cathode of the display panel; thereby selecting the unique display cell at the intersection of anode and cathode to light up; deflecting both beams accordingly to implement two-dimensional addressing; and adjusting beam current of the irradiating cathode to achieve image gray scale adjustment. The device using electron beam to scan for plasma matrix panel display, comprising a direct-current plasma display panel a plurality of display discharging cells formed at the intersections of the anodes and cathodes and switch cells formed at the intersections of the anodes and collection electrodes; two electron beam scanning, each comprising an electrode-any target screen where target electrodes are connected to display panel's anodes and cathodes, display supply whose output voltage is greater or equal to than the sum of the breakdown voltage of display discharging cell and the ionizing voltage of switch cell; and delay-circuit for longer pixel duty cycle. One electron beam seems anodes and closes the related switch cells to link display supply; another electron beam scans cathodes to make a unique moving display cell to emit light so as to realize two dimensional scanning and display.
