A display device for a portable object such as a timepiece comprising a lenticular array.

摘要

The invention relates to a device for displaying a pattern (1), said display device being intended to be integrated in a portable object such as a timepiece and comprising a lenticular network (8) through which is seen the pattern (1) and which is formed of a plurality of juxtaposed cylindrical lenses (10) extending parallel to each other. The cylindrical lenses (10) of the lenticular array (8) have a focal length such that the focal plane of the cylindrical lenses (10) coincides with the plane in which the pattern (1) extends. The pattern (1) is fragmented into straight strips (2) which extend parallel to one another, the straight strips (2) of the pattern (1) being nested between transparent rectilinear strips (6), so that there is always a rectilinear strip (2) of the pattern (1) located between two transparent strips (6). The rectilinear strips (2) of the pattern (1), just like the rectilinear transparent strips (6), follow each other with a pitch which is the same as that with which the cylindrical lenses (10) of the lenticular network (8) which covers the motif (1) succeed one another. Depending on the angle of view of an observer, the lenticular network (8) appears transparent or displays the pattern (1).
