Abstract: 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.

Abstract: A method for controlling the state of two or more liquid crystal-based switchable elements is proposed, wherein the switchable elements are configured as smart windows and/or as switchable subunits of smart windows, wherein in a first step a), at least two keyframes are defined, wherein each keyframe comprises setting values defining the intended state of a group of switchable elements. In a subsequent step b), a display frame is computed, wherein the display frame comprises setting values for the state of the group of switchable elements based on at least one of the defined keyframes. In a subsequent step c), the state of each of the switchable elements of the group of switchable elements is set as defined by the setting values of the computed display frame. Also, a master controller for use with the method, and a system implementing the method.
