Abstract[English]
An interactive touch-screen display device includes a liquid crystal layer; a conductive layer, the conductive layer being translucent and electronically grounded; a polarizer; and a glass layer, wherein the conductive layer contacts the glass layer and contacts the polarizer. Additionally, a method of assembling an interactive touch-screen display device includes creating an assembly by layering a liquid crystal layer and a polarizer. The method also includes bringing a conductive material proximate to the polarizer; creating a static charge on the conductive material to attract dust particles to the conductive material; and removing the conductive material, thereby carrying away dust particles.[French]
Un dispositif d'affichage à écran tactile interactif comprend une couche de cristaux liquides ; une couche conductrice, la couche conductrice étant translucide et mise à la terre électroniquement ; un polariseur ; et une couche de verre, la couche conductrice étant en contact avec la couche de verre et étant en contact avec le polariseur. De plus, un procédé d'assemblage d'un dispositif d'affichage à écran tactile interactif comprend la création d'un ensemble par stratification d'une couche de cristaux liquides et d'un polariseur. Le procédé consiste également à amener un matériau conducteur à proximité du polariseur ; à créer une charge statique sur le matériau conducteur pour attirer les particules de poussière vers le matériau conducteur ; et à retirer le matériau conducteur, ce qui permet d'évacuer les particules de poussière.
