Title
(EN) A CONTINUOUS ILLUMINATION PLASMA DISPLAY PANEL
(FR) ECRAN PLASMA A ECLAIRAGE CONTINU
Abstract
(EN)
A three electrode plasma display panel (PDP) operates in concurrent sustain (26) and addressing (24) periods, rather than separating the sustain and addressing periods (26 and 24). Because of this concurrent operation, a PDP with a brighter display is produced. Crosstalk between sustain electrodes and the column electrodes of non-selected rows is mitigated by implementing column voltages such that there is no difference in crosstalk brightness level in non-addressed pixels in the on state compared to non-addressed pixels in the off state. This is accomplished by choosing column voltages that are approximately symmetric about one-half of the sustain voltage.
(FR)
L'invention concerne un écran plasma (EP) à trois électrodes qui fonctionne par périodes concurrentes de soutien (26) et d'adressage (24) au lieu d'avoir des périodes de soutien et d'adressage séparées (26 and 24). Grâce au fonctionnement concurrent, on arrive à fabriquer un EP avec un affichage plus lumineux. On limite les interférences entre les électrodes de soutien et d'adressage en réglant la tension dans les colonnes de manière à ce qu'il n'y ait plus de différence entre les niveaux de luminosité des interférences dans les pixels non adressés à l'état 'allumé' et les pixels non adressés à l'état 'éteint'. On arrive à ce résultat en croisant les tensions de colonne qui sont à peu près symétriques à la mi-hauteur de la tension de soutien.
