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.
