Abstract
A flat display screen includes a cathode (1) with microtips (2) for the electron bombardment of the anode (5) having phosphor elements (7r, 7g, 7b), the cathode (1) and the anode (5) separated by a vacuum space (12) containing a progressive hydrogen release source comprised of a thin layer of hydrogenated material. The progressive hydrogen release source may comprise a resistive layer (11) of the cathode (1) on which the microtips (2) are arranged. The progressive hydrogen release source provides the microtips (2) with a substantially constant emitting power.
