Definitions

the rows of the grid 3 are sequentially polarized at a potential of the order of 80 volts, while the strips of phosphor elements (for example 7g in FIG. 1) to be excited are polarized under a voltage of the order 400 volts via the ITO strip on which these phosphors are deposited.
the ITO bands, carrying the other bands of phosphor elements (for example 7r and 7b in FIG. 1), are at low or zero potential.
the columns of cathode 1 are brought to respective potentials between a maximum emission potential and a non-emission potential (for example, 0 and 30 volts respectively). The brightness of a color component of each of the pixels of a line is thus fixed.
an insulating strip 8 can become such that it causes the formation of a destructive arc between the anode and the cathode.
the material is chosen so that its secondary emission coefficient is less than 1, at least in the energy range of the primary electrons emitted by the microtips.
the surface material 21 of the strips 20 has a secondary emission coefficient less than 1, it becomes negatively charged, as the screen operates, when the edge of the surface 21 receives primary electrons from microtips (not shown). This negative charge leads to the fact that the electrons are, unlike conventional screens, more and more repelled by the insulation bands 20.
