Abstract

Presentation by a display is enhanced by placing the active elements of the display at or substantially proximate to the surface of an electronic device. Such placement improves image quality, reduces shadow on the display, improves spill resistance, and minimizes the overall profile of the device.

Claims

1. A portable electronic device comprising:

one or more processors;

a memory coupled to the one or more processors;

a display coupled to the one or more processors to present content on the portable electronic device, the display comprising a first display element and a first active layer embedded in a surface of the display;

a protective sheet extending over a front side of the display; and

a battery comprising a second active layer, wherein the second active layer is integrated into the front of the battery and is positioned adjacent to the first active layer on a back side of the display and wherein the first active layer and the second active layer comprise a crosspoint array.

2. The portable electronic device of claim 1, wherein the crosspoint array comprises one or more of a capacitive array, a digital resistive array, or an interpolating force sensitive resistor (“

IFSR”

) array.

3. The portable electronic device of claim 1, wherein the first display element comprises one or more of an electrophoretic display element, a liquid crystal display element, a thin-film transistor matrix, or a light emitting diode display element.

4. The portable electronic device of claim 1:

the first active layer of the crosspoint array being located on a first side of a substrate; and

the second active layer of the crosspoint array being deposited onto the battery, the battery positioned adjacent to the first side of the substrate.

5. The portable electronic device of claim 1, wherein one of the second active layer or the first active layer is configured to extend beyond the other of the first active layer and the second active layer on at least three sides.

6. The portable electronic device of claim 1, further comprising:

a touch sensor controller coupled to the crosspoint array, wherein the touch sensor controller is configured to receive a first signal from the crosspoint array and to send a second signal to the one or more processors.

7. The portable electronic device of claim 1, wherein the crosspoint array comprises wires arranged at least in part over inter-pixel dead spaces.

8. A device comprising:

a display to present content on the device, the display comprising a first display element having an active area and a first crosspoint array layer; and

a second crosspoint array layer integrated into battery of the device, the second crosspoint array layer being positioned adjacent to the first crosspoint array layer, wherein the first crosspoint array layer and the second crosspoint array layer are located on a back side of the display and comprise a crosspoint array.

9. The device as recited in claim 8, further comprising a protective sheet extending over and covering the display.

10. The device as recited in claim 8, wherein the crosspoint array comprises one or more of a capacitive array, a digital resistive array, or an interpolating force sensitive resistor (“

IFSR”

) array.

11. The device as recited in claim 8, wherein the active area of the first display element comprises one or more of an electrophoretic display element, a liquid crystal display element, a thin-film transistor matrix, or a light emitting diode display element.

12. The device as recited in claim 8, wherein:

the first crosspoint array layer is located on a first side of a first substrate; and

the first display element is located on a second side of the first substrate.

13. The device as recited in claim 8, further comprising a touch sensor controller coupled to the crosspoint array, wherein the touch sensor controller is configured to receive a first signal from the crosspoint array and to send a second signal to one or more processors of the device.

14. The device as recited in claim 8, wherein the crosspoint array comprises wires arranged at least in part over inter-pixel dead spaces.

15. A method of assembling a device, the method comprising:

embedding a first layer of a crosspoint array into a first side of a substrate;

affixing at least a portion of a first display element with an active area to a second side of the substrate, wherein the first display element forms a portion of a display of the device and the first display element is proximate to a display surface of the device;

depositing a second layer of the crosspoint array onto a first side of a battery;

placing the first side of the substrate adjacent to the first side of the battery, wherein the battery is distal to the display surface of the device; and

placing a protective sheet extending over and covering the display surface.

16. The method as recited in claim 15, wherein the crosspoint array comprises one or more of a capacitive array, a digital resistive array, or an interpolating force sensitive resistor (“

IFSR”

) array.

17. The method as recited in claim 15, wherein the first display element comprises one or more of an electrophoretic display element, a liquid crystal display element, a thin-film transistor matrix, or a light emitting diode display element.

18. The method as recited in claim 15, further comprising:

coupling a touch sensor controller to the crosspoint array, wherein the touch sensor controller is configured to receive a first signal from the crosspoint array and to send a second signal to one or more processors of the device.
