Abstract
Apparatus including a first liquid crystal layer configured to receive at least a portion of an image and to provide the portion of the image across an angular viewing range; first substantially transparent electrodes positioned adjacent the first liquid crystal layer, the first electrodes being configured to have at least a first configuration in which a first subset of the electrodes provide electric fields across the first liquid crystal layer to form first transparent regions and first opaque regions in the first liquid crystal layer to provide a first angular viewing range, and a second configuration in which a second subset of the electrodes provide electric fields across the first liquid crystal layer to form second different transparent regions and second different opaque regions in the first liquid crystal layer to provide a second angular viewing range, having a different angular viewing range to the first angular viewing range.
