<p>Display apparatus 34 has one or more pixels 22 configured to provide images. A support 20 coupled to the pixels is configured to move between a plurality of positions, wherein when the support 20 is in a first position, the pixels 22 provide a first image in a first direction, and when the support 20 is in a second position, the pixels 22 provide a second image in a second direction. The support may be a reflector, such as a parabolic mirror and diffraction grating 36 may be provided to collimate the light. One viewer may view material such as a television broadcast while the other viewer views content such as a web-page. The device may determine the position of the eyes of the viewers in order to direct the desired content to them (see fig 8). The device may also be used to display three dimensional images.</p> |
