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.

Switchable imaging device, switchable optical device, and display

An electrowetting display device that features dual-mode operation. The display device can operate in either a low-power consumption bistable mode, or a higher-power consumption fast switching (video-rate) mode.

Dual-mode electrowetting display device

A display device for detecting light includes a display surface, at least one light sensitive element arranged behind the display surface, and a liquid crystal element arranged between the display surface and the at least one light sensitive element. The liquid crystal element is operative to polarization shift light incident on the at least one light sensitive element based on an orientation of the plurality of molecules. The display device further includes at least one electrode operative to change an orientation of the plurality of molecules. The at least one electrode is patterned to define a geometry of at least one field of view of the at least one light sensitive element. A controller is electrically coupled to the at least one electrode, wherein the controller is configured to apply a voltage to the at least one electrode to effect selection of the at least one field of view.
