AUTOSTEREOSCOPIC DISPLAY DEVICE HAVING A TRANSPARENT MODE OF OPERATION

摘要

A display device has a first, see-through mode of operation (30), (34) in which the display panel does not emit light and the display device blocks the light of a first polarization (state A) but allows light of a second polarization (state B) to pass through in both opposite directions. In a second, 3D display mode, the emissive pixels output light of the first polarization (state A) from the display output face and a view forming arrangement forms multiple views (36) in one output direction.

主权项

1. A display device comprising:
an emissive display panel having a display output face and comprising spaced apart light emissive display pixels; a polarization-sensitive view forming arrangement over the display output face, for directing light of a given first polarization from different pixels into different directions thereby enabling multiple views to be displayed in different directions simultaneously, wherein the view forming arrangement passes light of a second orthogonal polarization without significant change of direction; and a polarization filter for blocking light of the first polarization arranged on the opposite side of the display output face to the view forming arrangement, wherein the display device has at least two modes of operation: a first, see-through mode of operation in which the display panel does not emit light and the display device blocks the light of the first polarization but allows light of the second polarization to pass through in both opposite directions through the display device, through the spacing between the light emissive display pixels; and a second, 3D display mode in which the emissive pixels output light of the first polarization from the display output face and the view forming arrangement forms multiple views in one output direction.
