Display device with free focus capability
First Claim
1. A display device comprising:
- a display panel comprising a set of pixels the pixels being spatially distributed over the display panel, and each pixel being for providing a light output, the set of pixels comprising a plurality of different subsets of pixels, each subset of pixels comprising one or more pixels of the set of pixels, andan imaging unit that provides the light output of the one or more pixels of a subset of pixels to form pixel images on a plurality of view areas on an imaginary plane located at a first distance in front of the display,wherein the display panel provides a 3D display of a scene,wherein each view area of the plurality of view areas represents a view of the scene from a different viewpoint,wherein the plurality of view areas do not overlap each other,wherein each subset of pixels is associated with an imaging subunit of a plurality of imaging subunits,wherein each imaging subunit of the plurality of imaging subunits directs the light output of the subsets of pixels associated with the imaging subunit to the plurality of view areas,wherein the imaginary plane comprises an imaginary circle having a diameter equal to or smaller than that of the pupil of an eye,wherein the imaginary circle completely encloses at least two of the plurality of view areas,wherein, in a first time interval, each imaging unit provides the light output of a first subset of pixels to a first view area, and in a second time interval, each imaging unit provides the light output of the first subset of pixels to a second view area.

Abstract
A display device (40) comprising: a display panel (41) comprising a set of pixels (41R, 41L) the pixels being spatially distributed over the display panel, and each pixel being for providing a light output, the set of pixels comprising a plurality of different subsets (411) of pixels, each subset of pixels comprising one or more pixels of the set of pixels, an imaging unit (42) arranged for imaging the one or more pixels of a subset of pixels to form pixel images on a plurality of view areas on an imaginary plane located at a first distance in front of the display, the plurality of view areas not overlapping each other, with at least one pixel image of each one of the different subsets of pixels overlapping on a same one of the plurality of view areas, the imaginary plane comprising an imaginary circle having the diameter of the pupil of an eye, and the imaginary circle enclosing at least a part of at least two of the plurality of view areas, where the at least two of the plurality of view areas at least partly enclosed within the imaginary circle differ from each other with respect to at least one of the pixel images therein. The display system may be for one eye only or for two eyes of a viewer or for more eyes of more viewers.
