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.

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.
