Apparatus, methods and computer programs for configuring output of a display

摘要

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.

1. Apparatus comprising:
a display comprising a plurality of pixels; a first liquid crystal layer configured to receive at least a portion of an image displayed by the display and to provide the portion of the image across an angular viewing range; and a first plurality of substantially transparent electrodes positioned adjacent the first liquid crystal layer, the first plurality of electrodes having a subset of more than two electrodes aligned with a pixel in the display, wherein the subset of transparent electrodes is configured to provide an electric field across the first liquid crystal layer to form a first plurality of transparent regions for the pixel and a first plurality of opaque regions for the pixel in the first liquid crystal layer in order to provide a first angular viewing range over which the pixel is viewable, and the subset of transparent electrodes is configured to provide an electric field across the first liquid crystal layer to form a second plurality of different transparent regions for the pixel and a second plurality of different opaque regions for the pixel in the first liquid crystal layer in order to provide a second angular viewing range over which the pixel is viewable, wherein the second angular viewing range is different from the first angular viewing range.
