1. A device comprising:
- a first, non-emissive display comprising one or more non-emissive first-display pixels that are configured to operate in a plurality of modes comprising;
a first mode in which the one or more first-display pixels absorb or reflect visible light; and
a second mode in which the one or more first-display pixels are at least 70% transparent to visible light, wherein at least one first-display pixel comprises;
a front electrode oriented substantially parallel to a viewing surface of the display;
a first side electrode oriented substantially perpendicular to the viewing surface of the display; and
a second side electrode opposite the first side electrode and oriented substantially perpendicular to the viewing surface of the display and substantially parallel to the first side electrode, wherein;
a voltage difference exists between the two side electrodes when operating in the second mode such that the first side electrode has a polarity that is different from a polarity of the second side electrode,wherein the non-emissive display is a polymer-dispersed liquid-crystal display, an electrochromic display, an electro-dispersive display, or an electrowetting display; and
a second display disposed behind or in front of the first display, the second display configured to emit, modulate, absorb, or reflect visible light.

Abstract
In one embodiment, a device includes a first display which includes one or more first-display pixels that are configured to operate in multiple modes. The multiple modes include a first mode in which the one or more first-display pixels modulate, absorb, or reflect visible light and a second mode in which the one or more first-display pixels are substantially transparent to visible light. The device also includes a second display disposed behind or in front of the first display, the second display configured to emit, modulate, absorb, or reflect visible light.
