A method for controlling the state of two or more liquid crystal-based switchable windows includes in a first step providing correction data which define a relationship between a state signal and an output voltage level. The correction data is provided for each of the switchable windows and the state of the switchable windows may be adjusted according to the state signal between a minimum and maximum level. In a subsequent step, the state signal is provided which defines the desired state of one or more selected switchable windows. In a further step, a required voltage level is determined for setting the desired state based on the state signal and the respective correction data for each of the one or more selected windows. In a subsequent step d), an AC output voltage is generated having the required voltage level for each of the one or more selected windows.

Controller, system and method for controlling the state of liquid crystal-based switchable windows

Disclosed is a device for the regulation of light transmission. In particular, switchable windows and methods for their preparation are disclosed. The switchable windows include electrically switchable devices which in one optical switching state are capable of portraying closed patterns or images without the need for providing complex electrical contacting.

Device for the regulation of light transmission

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.
