Abstract: DESCRIPTIVE Micropoint emissive cathode electron source and field emission-excited cathodoluminescence display means using said source. The source comprises a series of electrodes (5) acting as cathode conductors and carrying micropoints (12) and a series of electrodes (10g) acting as grids, each of the electrodes of one of the series being in contact with a resistive layer (7) and having a lattice structure, so that there are consequently tracks (5a) which intersect and define first openings (6), each of the electrodes of the other series having second openings (11) which are displaced with respect to the first openings.

Abstract: Un dispositif d'éclairage pour afficheur à cristal liquide fournit en sortie un flux de lumière étendu polarisé. Il comprend une source de lumière 100 comprenant une couche à fort albédo A à la surface SD(A) d'émission de lumière, sur laquelle sont empilés une lame quart d'onde 101 et un polariseur réfléchissant 103. Il en résulte un gain de transmission de lumière de l'ordre de 1+A, qui permet de réaliser des afficheurs à forte luminance à faible consommation électrique.Application aux afficheurs à écran plat.

Abstract: The source comprises columns (4) emitting electrons and rows (6) of which the potential develops up to a positive value VI. The screen also comprises at least one supplementary column (24) common to all the rows, means (28) for carrying this supplementary column to a negative potential such that, irrespective of the potential of the rows which it crosses over, electrons may be emitted in the crossover zones, at least one supplementary anode (26) facing the supplementary column and means (30) for carrying this supplementary anode to a positive potential lower than VI. Each row is controlled by a single output transistor (32) which, when the latter is on, carries the line to VI and which, when off, disconnects the line from the voltage source VI. Application to microtip screens.

Abstract: System to control the form of a charged particle beam. The particle beam emanates from a source (58) of these particles. This source is associated with a collecting electrode which collects the particles. The system comprises at least one resistive zone (56) and at least two control electrodes (52, 54), this resistive zone and these control electrodes being arranged substantially at the same level as the source, these control electrodes being furthermore placed on either side of the resistive zone and intended for polarising the latter, the electrical resistance profile of the resistive zone being chosen so as to have the distribution of potential making it possible to obtain the desired form of the beam emanating from the source when the control electrodes are suitably polarised. Application to the focusing of a charged particle beam.
