    Abstract: The cathode structure of a flat display screen includes a substrate on which there are columns (15) of individually polarisable cathode conductors. These are associated with a resistive layer (11) on which electronic emission micropoints (2) are deposited. There is also provision to annul the effective lateral electric field between two neighbouring columns which are held at different potentials. Between two neighbouring columns there is an inter-column conductive track which is intended to be polarised to a potential at least equal to the minimal polarisation potential of the cathode conductors. These inter-column conductive tracks may be connected together by one of their ends. The structure may also comprise an insulating layer carried on the cathode conductors associated with the resistive layer. A grid conductor layer is then deposited on the insulating layer.

    Abstract: The screen has a cathode (2) formed of microdots arranged in columns (K1-K3) under an insulating coating which carries the pixel selection grid divided into rows (L1-L3). The colour selection grid has groups of slits (e.g. A1R,A1G,A1B) extending in the direction of the columns, each group covering the width of one column. Slits of the same rank in each group are connected to a common terminal. The anode is similarly divided into groups of parallel strips of luminophors of the primary colours, each strip corresponding to one slit, and all strips being returned to the same voltage.

    Abstract: A cathode-grid plate of a field-effect flat display screen of the type including a first set of row conductors, a second set of column conductors and, for each screen pixel, defined by the intersection of a column and of a line, an element for temporarily storing the luminance control signal of the considered pixel.

    Abstract: Method for fabricating a structure involves: forming on a substrate, first insulating layer, first level of metallization, second insulating layer and second level of metallization; opening first and second windows; forming third windows; engraving first level of metallization; engraving first insulating layer and simultaneously eliminating second insulating layer inside contour of second windows. A method for the fabrication of a structure consists of: (a) forming on a substrate (1) a pile of a first insulating layer (7), a first level of metallization (6), a second insulating layer (8) and a second level of metallization (9); (b) opening, in the second level of metallization and the second insulating layer, some first windows corresponding to the contour of the first openings and some second windows of which the external contour corresponds to the internal contour of the second openings; (c) forming in a masking layer (20) some third windows overlapping the first windows: (d) engraving the first level of metallization under the masking layer up to the internal periphery of the second windows; (e) engraving to a chosen distance the first insulating layer and simultaneously eliminating the second insulating layer inside the contour of the second windows; (f) and eliminating the masking layer.
