Estimating the term…
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.
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, wherein at least one of said first or said second electrode layer comprises an insulating layer, and an interface between said insulating layer and said containment space, wherein said interface is arranged for preventing migration of ions from said containment space into said insulating layer, for preventing charge accumulation in said insulating layer.
A method of manufacturing an electrowetting optical element, said method comprising the steps of providing a first electrode layer and a second electrode layer opposite said first electrode layer, and providing a containment space formed between said first and said second electrode layer, further comprising a step of providing on said first electrode layer an insulating layer, and providing an interface between said insulating layer and said containment space, wherein said interface is arranged for preventing migration of ions from said containment space into said insulating layer, for preventing charge accumulation in said insulating layer.
