Abstract: The present invention relates to a flat display screen anode of the type including an active area having phosphor elements, the active area being surrounded with at least one track in a material having a secondary emission coefficient lower than or equal to one.

Abstract: An anode (5) for a flat display screen includes at least one group of phosphor strips (7) deposited over corresponding electrode strips (17) separated one from another by an insulating layer (8) etched out in front of the phosphor strips (7), and at least one conductor (21) interconnecting the electrode strips (17) of the group of phosphor strips (7). Each of the electrode strips (17) is formed by a resistive strip (18) for receiving one phosphor strip (7) and at least one biasing strip (19) which is parallel to and joins the interconnecting conductor (21). The biasing strip (19) has a low resistivity with respect to the resistivity of the associated resistive strip (18). The biasing strip (19) is parallel to, laterally borders, and is in contacting engagement with the resistive strip (18). The anode (5) eliminates the risk of electrical arcs between the anode (5) and gate (3) or between adjacent phosphor strips (7) of the anode (5), without impairing the brightness of the screen.

Abstract: An anode for flat display screens, of the type including at least one set of phosphor strips disposed over corresponding conductive strips and at least one interconnection conductor for the phosphor strips. Each conductive strip of each set is connected through a resistor to the associated interconnection conductor.
