Abstract: PROBLEM TO BE SOLVED: To provide practically even screen luminance from one row to other rows by providing a line-to-line conductive track, and canceling a possible lateral electric field between plural rows of two adjacent cathode conductors having a different electrical potential. SOLUTION: A cathode 1' is divided into plural lines 15, and engaged with a grid 3, which is deposited on an insulating layer 21 and which is divided into plural lines. A grid conductive layer 3 and the insulating layer 21 are opened at a position of a microchip 2, and each picture element, which is regulated by each intersection of the plural lines 15 of the cathode 1' and the lines of the grid 3, is provided with several thousands microchips 2. A line-to-line conductive track 22 is deposited on a glass substrate 10 by an interposed material between the lines 15 of the cathode 1', and connected to one end of each other by a track 23. With this structure, the line-to-line conductive track 22 is biassed to a nearly equal electrical potential to the minimum biassing electrical potential of the lines 15 of the cathode 1'.

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.
