A display system which includes a first image display; a second image display; a reflective polarizer disposed between the first image display and the second image display, with the second image display disposed on a viewing side of the display system; and a controller for addressing image data to the first image display and the second image display, wherein the controller, the first image display and second image display are configured to selectively operate in accordance with: a first display function in which the first image display is visible to a viewer through the second image display and the second image display appears substantially transparent to the first image display; a second display function in which the display system appears as a plane mirror to the viewer; and a third display function in which the display system appears as a patterned mirror to the viewer.

Multiple function display system

A switchable imaging device () has a first mode of operation in which the device performs an imaging function and a second mode of operation different from the first mode, for example a non-imaging mode. In the first mode of operation the device comprises at least one first region that performs a lensing action and at least one second region that at least partially absorbs light passing through the or each second region. The switchable imaging device () may be disposed in path of light through an image display panel (). This provides a display that may be operable in either a directional display mode such as an autostereoscopic 3D display mode or a 2-D display mode, by controlling the switchable imaging device to be in its first mode or its second mode.
