Abstract

Components within a portable device are arranged around a perimeter of a display component to reduce the height of the portable device. Components such as a battery, a main logic board, a wireless networking interface, and so forth may be distributed around a display component such as an electrophoretic display. Distribution of components around the perimeter of the display component rather than behind the display component reduces the height. Furthermore, the placement of components in the perimeter provides a structure for a user to grip the portable device or for placement of user actuable controls.

Claims

1. A portable electronic book (eBook) reader device, comprising:

a display component having a perimeter;

a plurality of active components consuming, storing, or producing electrical power, wherein each active component of the portable eBook reader device other than the display component is arranged around at least a portion of the perimeter of the display component and substantially coplanar with the display component;

wherein the perimeter of the display component comprises at least four sides, and wherein plurality of active components comprise are disposed in the following arrangement;

a wireless module resides adjacent to a first edge of the perimeter of the display component;

a first battery resides adjacent to a second edge of the perimeter of the display component;

a second battery resides adjacent to a third edge of the perimeter of the display component; and

a main logic board resides adjacent to a fourth edge of the perimeter of the display component.

2. The portable eBook reader device of claim 1, wherein the perimeter of the display component comprises a plurality of edges within a plane defined by the length and width of the display component.

3. The portable eBook reader device of claim 1, wherein a plurality of batteries which are configured to provide operational power are disposed such that each battery is along a different edge of the perimeter of the display component.

4. The portable eBook reader device of claim 1, wherein the plurality of active components comprises:

a main logic board;

a wireless module; and

a battery.

5. The portable eBook reader device of claim 1, wherein the display comprises an electrophoretic display.

6. The portable eBook reader device of claim 1, wherein the display component resides between two or more components.

7. The portable eBook reader device of claim 1, further comprising one or more interconnects configured to couple the display component with at least one of the plurality of active components.

8. The portable eBook reader device of claim 7, wherein the interconnect is integral to at least the display component or one of the plurality of active components.

9. A device comprising:

a display component defining a plane and having a perimeter;

a circuit board coupled to the display component and disposed approximately within the plane of the display component and along at least a portion of a first side of the perimeter of the display component; and

one or more batteries coupled to the circuit board and disposed approximately within the plane of the display component and along at least a portion of a second, different side of the perimeter of the display component;

wherein each component of the device that consumes, stores or produces electrical power, other than the display component, is arranged around at least a portion of the perimeter of the display component and not disposed behind the display component.

10. The device of claim 9, wherein the plane of the display component is defined by the length and width of the display component.

11. The device of claim 9, wherein the display component is substantially polygonal.

12. The device of claim 9, further comprising a wireless module disposed along at least a portion of a third side of the perimeter of the display component.

13. The device of claim 9, wherein the device embodies a portable electronic book (eBook) reader device.

14. The device of claim 9, wherein the display component comprises an electrophoretic display.

15. The device of claim 9, wherein the circuit board comprises:

a processor;

an image processing unit; and

an external memory interface.

16. The device of claim 9, wherein the circuit board comprises a wireless modem configured to establish a wireless wide area networking connection.

17. The device of claim 9, wherein the circuit board couples to the display component, the one or more batteries, or both, via one or more interconnects.

18. The device of claim 17, wherein the one or more interconnects comprise:

an electrical conductor;

an optical path;

an electromagnetic waveguide;

a fluidic channel;

or

a mechanical joint.

19. A method of assembling an electronic device, comprising:

attaching a first active component of the electronic device to a side of a perimeter of a display component of the electronic device such that the first active component and the display component reside substantially within a same plane; and

attaching a second, different active component of the electronic device to a side of the perimeter of the display component of the electronic device such that the second active component resides substantially within the same plane as the first active component and the display component;

the assembling performed such that each component of the electronic device that consumes, stores or produces electrical power, other than the display component, is arranged around at least a portion of the perimeter of the display component and substantially coplanar with the display component.

20. The method of claim 19, wherein the side of the perimeter of the display component to which the first active component attaches is different than the side of the perimeter of the display component to which the second active component attaches.

21. The method of claim 19, wherein each of the first and second active components consumes, stores, or produces electrical power.

22. The method of claim 19, further comprising attaching a non-active component of the electronic device to a portion of the electronic device, the non-active component comprising a groundplane and attaching behind the display component.

23. The method of claim 19, further comprising interconnecting the display component, the active components, or both, via one or more interconnects.

24. The method of claim 23, wherein at least one of the interconnects extends at least partially in front of or behind the display component.

25. The method of claim 19, further comprising placing an enclosure at least partially over the display component, the active components, or both.

26. The method of claim 25, wherein the enclosure comprises a pre-formed shell.

27. The method of claim 25, wherein the enclosure comprises an encapsulating shell formed around at least a portion of the display component, the active components, or both.
