Abstract
The present invention relates to a flat display screen, comprising a cathode with electron emission microtips associated with a grid for extracting electrons from the microtips, the cathode/grid comprising conductive grid or cathode lines adapted to being sequentially addressed, and cathode or grid columns perpendicular to the lines and adapted to being addressed individually and simultaneously during the addressing of a line, and the screen comprising a return electrode adapted to being biased to a return potential corresponding to a no electron emission potential, each grid or cathode line being connected, via at least one resistive element, to the return electrode.
