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

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 stat...

Zusammenfassung:	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.
