Definitions

  • Another object of the present invention is to provide such a method which also solves breakdown problems in color screens or monochrome screens.
  • the screen is a microtip color screen
  • each anode is divided into at least two separately addressable portions
  • the regeneration phases are performed on a first portion while an image is in progress of formation on another portion and, during a regeneration phase, a first portion of anode is low potential and the microtips and gates facing are polarized in an emission state.
  • said regeneration phase is interposed between each frame.
