Abstract
A switchable optical device is provided having a first substrate (), a second substrate () and a seal (). The two substrates () and the seal () are arranged such that a cell having a cell gap is formed and a switchable medium () is located inside the cell gap. The first substrate () has a first transparent electrode () and the second substrate () has a second transparent electrode (). The electrodes () are facing towards the cell gap. The two substrates () are arranged such that the first substrate () has a first region () adjacent to a first edge () of the first substrate () which does not overlap with the second substrate () and the second substrate () has a second region () which does not overlap with the first substrate (). A first electrically conducting busbar () is arranged in the first region () and a second electrically conducting busbar () is arranged in the second region (). A first terminal is electrically connected to the first busbar () and a second terminal is electrically connected to the second busbar (). The first substrate () and the second substrate () each have an edge deletion () in which the respective transparent electrode () is removed. The edge deletion () is complete on the edges non-adjacent to a busbar () and there is no edge deletion or only partial edge deletion on edges adjacent to a busbar (). Further aspects of the invention relate to a method for designing a switchable optical device, a method for driving a switchable optical device, a method for manufacturing a switchable optical device and a system comprising a switchable optical device and a controller for driving the switchable optical device.
