Abstract

L'invention concerne un dégazeur d'écran à cristaux liquides qui permet d'obtenir un niveau de vide élevé grâce à l'absorption des restes de gaz à l'intérieur d'un récipient fermé, ladite absorption étant mise en oeuvre grâce à une réaction chimique produite dans un premier vide formé par une pompe à vide. L'invention s'utilise en particulier exclusivement dans la lampe fluorescente à cathode froide (CCFL) d'un écran à matrice active (écran TFT) comprenant du mercure et un élément structural du dégazeur. Le dégazeur est non seulement utile pour obtenir un niveau de vide élevé dans une lampe fluorescente plate (FFL) à rétroéclairage utilisant une certaine quantité de mercure, mais aussi dans une sorte de lampe à gaz inerte comprenant une très faible quantité de mercure.
