Abstract: A method for controlling the state of two or more liquid crystal-based switchable elements (10) is proposed, wherein the switchable elements (10) are configured as smart windows (2) and/or as switchable subunits (4) of smart windows (2). The method comprises a first step a) in which at least two keyframes are defined, wherein each keyframe comprises setting values defining the intended state of a group of switchable elements (10). The group may either be a selection of one or more specific switchable elements (10) or all available switchable elements (10). 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 (10) based on at least one of the defined keyframes. After computing of the display frame, the state of each of the switchable elements (10) of the group of switchable elements (10) is set as defined by the setting values of the computed display frame in a subsequent step c) of the method. Further aspects relate to a master controller (20) for use with the method and a system (1) implementing the method.

Abstract: A method for controlling the state of two or more liquid crystal-based switchable windows (30) is provided. In a first step a) of the method, correction data is provided which define a relationship between a state signal which defines the desired state and an output voltage level which defines the output voltage required to set the desired state, wherein the correction data is provided for each of the two or more switchable windows (30) and wherein the state of the switchable windows (30) may be adjusted according to the state signal between a minimum level and a maximum level. In subsequent step b), the state signal is provided which defines the desired state of one or more selected windows of the two or more switchable windows (30). In a further step c), 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. Further aspects of the invention relate to a controller (20) and a building management system (100) for controlling the state of two or more liquid crystal-based switchable windows (30).
