Abstract

A touch screen display having a touch screen directly coupled to a display is described herein. The display may be an interferometric modular display. The touch screen may be directly laminated to a glass substrate in the display, or the touch screen may be directly laminated to a diffuser film in the display. Alternatively, the display can be any type of display that is not sensitive to pressure.

Claims

1. A touch screen display comprising:

a touch screen; and

a pressure tolerant display including a plurality of interferometric modulator elements;

wherein the touch screen is directly coupled to the display; and

wherein the display comprises

a substrate having a first and second surface,

a film stack deposited on the first surface of the substrate, and

at least one metallic membrane forming an interferometric cavity with the film stack, wherein the distance between the metallic membrane and the film stack determines the color produced by each of the interferometric modulator elements.

2. The touch screen display of claim 1 wherein the touch screen is laminated to the display.

3. The touch screen display of claim 1 wherein the touch screen is a pressure sensitive touch screen.

4. The touch screen display of claim 3 wherein the display comprises:

a seal coupled to the first surface of the substrate; and

a packaging component coupled to the seal.

5. The touch screen display of claim 1 wherein the

metallic membrane is coupled to the first surface of the substrate to cover the film stack.

6. The touch screen display of claim 1 wherein the touch screen is directly coupled to the second surface of the substrate.

7. The touch screen display of claim 1 wherein the display further comprises a front-surface element coupled to the second surface of the substrate.

8. The touch screen display of claim 7 wherein the touch screen is directly coupled to the front surface element.
