Abstract
L'invention concerne des procédés et des structures permettant de réduire l'accumulation de charge sur les parois d'espacement d'un écran plat. Dans un mode de réalisation, l'ordre d'activation des éléments émetteurs d'électrons adjacents aux éléments d'espacement est modifié de sorte que ces derniers soient activés avant les éléments émetteurs d'électrons qui chargent les éléments d'espacement (501, 502, 503) à un niveau indésirable. Dans un autre mode de réalisation, les électrodes de face (501a, 502a, 503a) qui sont placées sur la surface de l'élément d'espacement sont connectées à un bus commun (504), répartissant ainsi la charge accumulée sur l'un quelconque des éléments d'espacement. Le bus commun (504) peut, de plus, être connecté à un condensateur (1010) qui est placé à l'intérieur ou à l'extérieur de la zone active de l'écran plat, ce qui augmente la constante de temps de charge des éléments d'espacement. Le condensateur peut être connecté à la terre ou à une alimentation en haute tension (1011). dans un autre mode de réalisation, la constante de temps de charge des éléments d'espacement est augmentée du fait que ces derniers sont fabriqués dans un matériau ayant une constante diélectrique élevée, telle qu'une dispersion d'oxyde d'aluminium, d'oxyde de chrome et d'oxyde de titane, l'oxyde de titane représentant environ quatre pour cent du matériau constitutif de l'élément d'espacement.
