Abstract
A coplanar sustaining plasma panel, and particularly an electrode arrangement make is possible to better contain the sustaining discharges in a predetermined zone. Plasma panel (10) of the invention comprises addressing electrodes (X1 to X3) crossed with sustaining electrodes arranged by pair (p1, p2), each sustaining electrode pair being formed of an addressing-sustaining electrode (Y1, Y2) and a sustaining-only electrode (E1, E2). A pixel (PX1 to PX6) consists approximately at each crossing of an addressing electrode (X1, X2, X3) with a sustaining electrode pair (p1, p2). At least one of two electrodes (Y1, E1) of same pair (p1) comprises, at the level of each pixel (PX1 to PX6), a projecting surface (SB1 to SB3, SC1, SC3) oriented toward the other electrode. According to a characteristic of the invention, projecting surfaces (SB1 to SB3, SC1 to SC3) are arranged so that between two consecutive pixels (PX1 to PX6) of same pair (p1, p2), of the two closest projecting surfaces, one belongs to an addressing-sustaining electrode (Y1, Y2) and the other to a sustaining-only electrode (E1, E2).
