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.
