<p>The invention relates to a plasma display panel comprising a reduced-section discharge expansion zone. The inventive panel comprises two plates which are separated by a gas-filled space that is partitioned by separation elements (15, 19) forming a network of barriers, and networks of coplanar keep-alive (Y, Y') and addressing (X) electrodes. According to the invention, each cell (17) is subdivided into a trigger zone (Z<SB>M</SB>, Z<SB>M'</SB>) at each intersection between an addressing electrode and a keep-alive electrode. Moreover, at least one coplanar discharge expansion zone (Z<SB>E</SB>; Z<SB>E1</SB>, Z<SB>E2</SB>) extends between the aforementioned trigger zones (Z<SB>M</SB>, Z<SB>M'</SB>). The network of barriers is adapted such that, in each cell, the width of each coplanar expansion zone (Z<SB>E</SB>; Z<SB>E1</SB>, Z<SB>E2</SB>) is less than that of all of the trigger zones (Z<SB>M</SB>, Z<SB>M'</SB>). The light output of the panel can be significantly improved by applying a keep-alive discharge control method to the panel by means of matrix triggering.</p> |
