Title
(EN) CHOLESTERIC LIQUID CRYSTAL DISPLAY (LCD) DEVICE, AND METHOD FOR ITS PRODUCTION
(FR) DISPOSITIF AFFICHEUR A CRISTAUX LIQUIDES CHOLESTERIQUE (LCD) ET SON PROCEDE D'OBTENTION
Abstract
(EN)
A liquid crystal device is disclosed, having one or several display segments, and comprising: a first display substrate, a second display substrate, a layer of liquid crystal material disposed between said first and second substrate; and layer of conductive material disposed on said substrates. The conductive layers form electrodes for applying an electric field across the liquid crystal for switching the liquid crystal material between a first optical state and a second optical state different from said first optical state. Image features of the display are further defined by the inclusion of a layer of patterned non-conductive or passive dielectric material on at least one of the substrates, said patterned material forming a mask defining image elements of the display segments.
(FR)
Dispositif à cristaux liquides comportant un ou plusieurs segments d'affichage et un premier substrat d'affichage, un second substrat d'affichage, une couche de matière de cristaux liquides venant entre les deux substrats; et une couche de matière conductrice venant entre les substrats. Les couches conductrices forment des électrodes assurant l'application d'un champ électrique sur le cristal liquide en vue de la commutation de la matière du cristal liquide entre un premier état optique et un second état optique différent du premier état optique. On définit ensuite les caractéristiques d'image de l'afficheur par insertion d'une couche de matière diélectrique à motifs non conductrice ou passive sur au moins un des substrats, la matière formant un masque définissant des éléments d'image sur les segments d'affichage.
