Abstract

An electronic reading device includes a mid-frame structure such that the mid-frame structure can include a reverse draft. A reverse draft corresponds to a back of the electronic reading device being a predetermined amount wider than a front of the electronic reading device. Additionally, a co-molded mid-frame stiffener provides a predetermined rigidity of the electronic reading device. The electronic reading device also includes a display integrated with the front of the mid-frame structure, wherein a space between the display and the mid-frame structure includes one or more electronic reading device components. Similarly, a back cover is integrated with the back of the mid-frame structure, wherein a space between the back cover and the mid-frame structure includes additional electronic reading device components.

Claims (44)

1. An electronic device, comprising:

a mid-frame structure including a reverse draft corresponding to a back of the electronic device being a predetermined amount wider than a front of the electronic device,

wherein a space between the front of the electronic device and the mid-frame structure includes a first group of one or more electronic components, and

wherein a space between the back of the electronic device and the mid-frame structure includes a second group of one or more electronic components.

2. The electronic device of claim 1 , wherein

the reverse draft is at least a seven-degree reverse draft corresponding to the back of the electronic device being at least seven degrees wider than the front of the electronic device.

3. The electronic device of claim 1 , wherein

the electronic device has a depth of less than seven millimeters.

4. The electronic device of claim 1 , wherein

the mid-frame structure includes a co-molded mid-frame stiffener providing a predetermined rigidity of the electronic device.

5. The electronic device of claim 4 , wherein

the co-molded mid-frame stiffener includes an injection molded magnesium stiffener.

6. The electronic device of claim 1 , wherein

the mid-frame structure includes a portion to house a power button.

7. The electronic device of claim 5 , wherein

the co-molded mid-frame stiffener includes a portion to house a power button.

8. The electronic device of claim 6 , wherein

the power button is disposed at a first corner of the mid-frame structure.

9. The electronic device of claim 8 , wherein

the power button is axially aligned with a tri-color status light-emitting diode (LED) integrated into the front of the mid-frame structure.

10. The electronic device of claim 1 , wherein

the first group of one or more electronic device components includes at least one of a daughter printed circuit board (PCB), an electronic paper display flexible printed circuit, a front light flexible printed circuit, a touch panel flexible printed circuit, and adhesive tape.

11. The electronic device of claim 1 , wherein

the second group of one or more electronic device components includes at least one of adhesive tape, an electrostatic discharge member, a battery, and a main printed circuit board (PCB).

12. The electronic device of claim 1 , wherein

the electronic device is an electronic reading device.

13. The electronic device of claim 1 , further comprising:

a display integrated with the mid-frame structure, wherein the display is an electronic paper display.

14. The electronic device of claim 13 , wherein

the display includes a front light.

15. The electronic device of claim 14 , further comprising:

a touch panel integrated with the display.

16. A method for reducing the depth of an electronic device, the method comprising:

disposing a mid-frame between a front of the electronic device and a back of the electronic device as a mid-frame structure, the mid-frame structure including a reverse draft;

integrating a first group of electronic device components between the front of the electronic device and the mid-frame; and

integrating a second group of electronic device components between the back of the electronic device and the mid-frame.

17. The method of claim 16 , wherein

the reverse draft corresponds to the back of the electronic device being a predetermined amount wider than the front of the electronic device.

18. The method of claim 17 , wherein

the reverse draft is at least a seven-degree reverse draft corresponding to the back of the electronic device being at least seven degrees wider than the front of the electronic device.

19. The method of claim 16 , wherein

the first group of one or more electronic device components includes at least one of a daughter printed circuit board (PCB), an electronic paper display flexible printed circuit, a front light flexible printed circuit, a touch panel flexible printed circuit, and adhesive tape.

20. The method of claim 16 , wherein

the second group of one or more electronic device components includes at least one of adhesive tapes, an electrostatic discharge member, a battery, and a main printed circuit board (PCB).
