Patent

CA 2167591

The disclosure is directed to a color liquid crystal display (LCD) using a diffuse light source (10), input and output microlens matrices (16, 24), a color filter layer (14) and an LCD matrix (18) sandwiched between two solid transparent layers (20, 22). The color filter layer is deposited directly upon one of the microlens plates and not upon the glass substrate of the LCD. Thus, a wider variety of substances, primarily dyes, can be used. A wide viewing angle is obtained for a user by virtue of the microlens output. Too, the microlens input plate allows more light from the source to be used.

Affichage à cristaux liquides coloré utilisant une source diffuse de lumière (10), des matrices microlenticulaires d'entrée et sortie (16, 24), une couche filtrante colorée (14) et une matrice de LCD (18) enserrée entre deux couches transparentes pleines (20, 22). La couche filtrante colorée (14) est déposée directement sur l'une des deux plaques microlenticulaires et non sur le substrat de verre de la LCD. Il est ainsi possible d'utiliser une plus grande variété de substances, et en premier lieu des teintures. L'utilisateur bénéficie grâce aux microlentilles d'un large angle de vision. De plus, les plaques microlenticulaires d'entrée permettent une meilleure utilisation de la lumière de la source.
