Abstract
In one embodiment, a display screen includes one or more pixels that are configured to operate in multiple modes. The multiple modes include a first mode in which the one or more pixels modulate, absorb, or reflect visible light and a second mode in which the one or more pixels are substantially transparent to visible light. When the one or more pixels are in the second mode a component behind the display screen is viewable through the one or more pixels.

A device comprising a plurality of display screens comprising:
- a first display screen comprising a first viewing surface, the first display screen comprising a plurality of first display pixels;
- a second display screen comprising a second viewing surface in front of the first display screen and parallel to the first viewing surface, the second display screen comprising a plurality of second display pixels, each of the plurality of second display pixels comprising:
- an enclosure containing electrically controllable material that is moveable within a volume of the enclosure, the electrically controllable material being at least partially opaque to visible light;
- wherein:
- located above each first display pixel of the first display screen are at least two of the plurality of second display pixels;
- each second display pixel overlays only one first display pixel in a direction perpendicular to the first and second viewing surfaces;
- and
- each of the plurality of second display pixels is configured to operate in a plurality of modes comprising:
- a first mode in which the second display pixel modulates, absorbs, or reflects visible light;
- a second mode in which the second display pixel is substantially transparent to visible light;
- and
- a third mode in which the second display pixel is partially transparent to visible light.
