Abstract
The invention relates to a transparent component (100) comprising active members (10) that are juxtaposed in parallel to a surface of the component, and that are each switchable between a transparent state and a reflecting state. Each active member establishes a light path between a light passage opening and a side of the component when said active member is reflecting. An addressing system (2) further controls the switching of the active members so that a reduced number of active members is simultaneously reflecting. Therefore, an image formed by transparency through the component thus appears permanently and continuously. Such a transparent component can be used for making an image superimposition device and an image display and storage device.
