Abstract

An electronic display arrangement comprises at least one electro-optical display means, as for example a liquid crystal cell, a certain number of elementary patterns associated with the electro-optical display means, such elementary patterns for the most part conforming to and being based on a series of stylized and selected alpha-numeric characters in the form of a composite mosaic-type structure the grid of which is formed by the patterns which exhibit heterogeneous and complementary contours arranged so as to nest into one another in a manner similar to that of a puzzle, the arrangement being characterized in that the mosaic is divided up by optically passive bands which partially cover over certain of the elementary patterns and form a cutup of the mosaic. The electronic display arrangement is applicable to panels for displaying alpha-numeric characters for the visualization of messages in public places such as railway or airport halls.

Dependent claims

An electronic display arrangement having at least one electro-optic display means including elementary patterns conforming to and being based on a series of stylized and selected alpha-numeric characters in the form of a composite mosaic type structure, said mosaic-type structure being formed by:

forming in a grid layer curved separations having a width (Y),
forming in said grid layer diagonally extending separations having said width (Y), said diagonally extending separations including a first group and a second group of separations with separations in said first group intersecting separations in said second group,
forming in said grid layer horizontally extending separations having said width (Y),
said curved separations, said diagonally extending separations and said horizontally extending separations dividing said grid layer into a mosaic of elementary patterns of different sizes and shapes, some of said elementary patterns exhibiting homogenous and complementary contours so that one elementary pattern nests within another elementary pattern;
and
overlaying with a plurality of optically passive bands regions in said grid layer in which said diagonally extending separations intersect, said optically passive bands having first edges which, with said diagonally extending separations, define optically passive regions of small surface, said optically passive bands having a width (X) which is greater than said width (Y) and the widths of said regions of small surface.
