Back-to-back displays
First Claim
1. A two-sided electronic display device, comprising:
- a first display device comprising a first transparent substrate, a first backplate and a first opaque layer comprising a first set of pixel elements, wherein the first opaque layer is disposed between the first transparent substrate and the first backplate and wherein the first set of pixel elements is configured to transmit light through the first transparent substrate;
a second display device comprising a second transparent substrate, a second backplate and a second opaque layer comprising a second set of pixel elements, wherein the second opaque layer is disposed between the second transparent substrate and the second backplate and wherein the second set of pixel elements is configured to transmit light through the second transparent substrate; and
a fastener affixing the first backplate to the second backplate.

Abstract
Two-sided, back-to-back displays are formed by sealing the backplates of two displays against one another. Mechanical parameters of the backplates, e.g., stiffness and strength, do not meet the requirements for standalone one-sided displays which are otherwise similar to the two displays. However, when sealed against one another, the backplates reinforce each other to meet or exceed the requirements for both one-sided and two-sided displays. The presence of backplates on each of the constituent one-sided displays allows one or both of those displays to be individually tested, thereby increasing the production yield of the back-to-back displays. The display elements of the displays can comprise interferometric modulators.
