Device with a mid-frame structure and reverse draft
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.

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 electro static 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 , 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:
combining a front cover, a back cover and a mid-frame disposed between the front cover and the back cover to provide a mid-frame structure, the mid-frame structure comprising a reverse draft;
integrating a first group of electronic device components between the front cover and the mid-frame; and
integrating a second group of electronic device components between the back cover and the mid-frame.
17. The method of claim 16 , wherein
the reverse draft corresponds to a back of the electronic device being a predetermined amount wider than a front of the electronic device.
18. The method of claim 17 , wherein
the reverse draft is at least a 7 degree reverse draft corresponding to the back of the electronic device being at least 7 degrees wider than the front of the electronic device.
