Apparatus for displaying information

摘要

The invention relates to an apparatus for displaying information by way of at least one fluid. For this purpose, the apparatus comprises at least one display element having two volumes, wherein the first volume is disposed between a transparent cover layer and a non-transparent intermediate layer and the second volume is disposed between the intermediate layer and a final layer such that only the content of the upper volume is visible. The display according to the invention further comprises at least one fluidic transition, by way of which the fluid can be transported between the two volumes. The apparatus according to the invention has an optimized space requirement, solves the problem of uneven saturation over the surface of a display element, and is additionally not sensitive to mechanical interference.

主权项

1. An apparatus for displaying information, comprising at least one display element, including:
a fluid, the surface energy of which can be varied by means of an electric field; a first and a second volume for receiving said fluid, wherein only the first volume is visible and the volumes are separated by a non-transparent intermediate layer; and a fluidic transition between said first and said second volume, wherein said first volume is arranged between an optically transparent cover layer and said non-transparent intermediate layer and said second volume is arranged between said intermediate layer and a final layer and all layers are parallel across their entire area, and wherein said first and said second volume and the volume of the fluid are equal; the fluidic transition connects a lateral end of said first volume with a lateral end of said second volume fluidically, in viewing direction perpendicular to the visible first volume, so that the fluid volume is conveyed dimensionally stable from the one volume into the other volume parallel to the layers to the fluidic transition, so that always that fraction of the fluid volume which is present in the visible volume extends over the entire height between said cover layer and said intermediate layer, and so that when discharging the fluid, a fluid-free space occurs in the respectively emptied volume at the end opposite the lateral end.
