20130278994 | ELECTROWETTING OPTICAL ELEMENT - An electrowetting optical element comprising a first electrode layer stack and a second electrode layer stack, and a containment space formed between said first electrode layer stack and said second electrode layer stack, one or more pixel walls fixedly mounted on said second interface surface and extending between said first and second electrode stacks, for defining sides of said containment space. Said containment space at least contains a polar liquid and a non-polar liquid, the polar and non-polar liquids being immiscible with each other. Said hydrophobic interface surface has a higher hydrophobicity than the second interface surface. The electrowetting element is arranged for enabling powering of said first and second electrode layers for rearranging said polar liquid relative to said non-polar liquid. An end face of said one or more pixel walls opposite said first electrode layer stack faces said hydrophobic interface surface in a loose manner. | 10-24-2013 |
20110235146 | ELECTROWETTING OPTICAL ELEMENT ARRANGED FOR PREVENTING CHARGE ACCUMULATION, AND METHOD FOR MANUFACTURING AN ELECTROWETTING OPTICAL ELEMENT - An electrowetting optical element comprising a first electrode layer and a second electrode layer opposite said first electrode layer, and a containment space formed between said first and said second electrode layer. The first electrode layer comprises an insulating layer, and a hydrophobic surface layer contiguous to said containment space. The electrowetting element further comprises a barrier layer in between said insulating layer and said containment space, for preventing ion migration of ions from said containment space into said insulating layer, for preventing charge accumulation in said insulating layer. The disclosure further relates to a method of manufacturing an electrowetting element. | 09-29-2011 |
