| 20110235157 | Display device comprising display elements without backflow ducts - The invention relates to a display device having at least one electronically controllable display element comprising at least one non-polar and at least two electrically conducting or polar liquids, a fluidically closed volume having a visible subvolume, a further subvolume and at least two storage volumes connected to said subvolumes, as well as a voltage source connected to a first electrode array. It is provided thereby that each of said electrically conducting or polar liquids assumes a volume which is dimensioned such that, independent of application of voltage to the electrode array, always a fluidically tight closure for non-polar liquid between the respective storage volume and either the visible or the further subvolume is formed. | 09-29-2011 |
