Abstract
A display device uses liquids for visualizing information and comprises a plurality of display elements with cavities, at least one display liquid for displaying information, at least one liquid feeding mechanism for delivering the at least one display liquid, at least one common main duct for jointly filling a plurality of display elements, and at least one liquid reservoir for temporarily holding the at least one display liquid. The at least one liquid feeding mechanism allows display liquid to be delivered from reservoir into said display elements via the common main duct leading into at least two display elements. Each display element has at least one mechanism for influencing the surface energy of the display liquid. In the method of the invention, different feeding processes can be used for holding or delivering the desired liquid into the display elements.
