Abstract

A fascia member (200) for a wireless telecommunication device (700) or other electronic device includes a thin, flexible membrane (201) having a transparent, reinforcing member (212) coupled thereto. The thin, flexible membrane (201) includes a transparency region (203) and a deflectable key region (204). The thin, flexible membrane (201) may thus serve as a major front face for the wireless telecommunication device (700) with no break lines between display and keypad. Printing on one side of the thin, flexible membrane (201) provides alphanumeric indicia (207) and graphical designs for the wireless telecommunication device (700). Printing may also be applied to the transparent, reinforcing member (212).

Claims

1. A reinforced unitary fascia member for an electronic device comprising a thin, flexible membrane having at least a transparency region and a deflectable key region and a reinforcing member, the deflectable key region functioning as a surface for a plurality of depressible keys.

2. The unitary fascia member of claim 1, wherein the reinforcing member comprises a rigid, transparent material coupled to a sub-portion of the thin, flexible membrane.

3. The unitary fascia member of claim 2, wherein the rigid, transparent material comprises one of glass, plastic, or coated plastic.

4. The unitary fascia member of claim 3, wherein the rigid, transparent material comprises coated plastic manufactured from one of coated polycarbonate or coated polymethylmethacrylate resin.

5. The unitary fascia member of claim 2, wherein the thin, flexible membrane comprises a front face and a rear face, wherein the rigid, transparent material is disposed along the rear face.

6. The unitary fascia member of claim 5, wherein the rigid, transparent material is disposed over at least the transparency region.

7. The unitary fascia member of claim 2, wherein the rigid, transparent material comprises one of glass, plastic, or coated plastic spanning the transparency region along a rear face of the thin, flexible membrane.

8. The unitary fascia member of claim 7, further comprising a second rigid, transparent material spanning the transparency region along a front face of the thin, flexible membrane.

9. The unitary fascia member of claim 8, wherein the second rigid, transparent material is one of glass, plastic, or coated plastic.

10. The unitary fascia member of claim 1, wherein the reinforcing member is affixed to the thin, flexible membrane by a layer of adhesive.

11. The unitary fascia member of claim 10, wherein the layer of adhesive comprises ultra-violet reflective adhesive.

12. The unitary fascia member of claim 1, wherein the thin, flexible membrane comprises printing disposed thereupon, the printing comprising alphanumeric indicia for the plurality of depressible keys.

13. The unitary fascia member of claim 12, wherein the alphanumeric indicia comprise telephone keypad graphics.

14. The unitary fascia member of claim 1, wherein the thin, flexible membrane comprises a plastic film having a thickness of between 0.1 and 1 millimeters.

15. The unitary fascia member of claim 1, further comprising an electronic device housing member, wherein the thin, flexible membrane is affixed to the electronic device housing member by one of press-fit attachment, snaps, pressure sensitive adhesive, liquid adhesive, or ultrasonic welding.

16. The unitary fascia member of claim 1, wherein the thin, flexible membrane comprises at least one deflectable key region aperture passing between a first depressible key and a second depressible key.

17. A fascia assembly for a portable electronic device, the fascia assembly comprising:

a fascia, comprising;

a thin, flexible film having at least a transparency region and a deflectable key region, the deflectable key region functioning as a plurality of depressible keys; and

a transparent, reinforcing member affixed to a subregion of the thin, flexible film, the subregion covering at least the transparency region; and

a keypad module adhered to the fascia, the keypad module comprising;

a printed circuit board having a plurality of switches disposed thereon; and

a semi-rigid polymer layer disposed between the fascia and the printed circuit board.

18. The fascia assembly of claim 17, wherein the unitary fascia member comprises at least one deflectable key region aperture passing between a first depressible key and a second depressible key, further comprising a pliable guidance layer comprising at least one tactile rib, the pliable guidance layer being disposed between the semi-rigid polymer layer and the unitary fascia member such that the at least one tactile rib protrudes through the at least one deflectable key region aperture.

19. A wireless telecommunication device having a major front face, the wireless telecommunication device comprising:

a fascia assembly comprising a thin, flexible membrane spanning substantially the major front face, the thin, flexible membrane having at least a transparency region and a deflectable key region, the deflectable key region functioning as a plurality of depressible keys, and a transparent, reinforcing member affixed to the thin, flexible membrane, the transparent, reinforcing member covering the transparency region without covering the deflectable key region;

a display module disposed within the wireless telecommunication device so as to be viewable through the transparency region of the fascia assembly; and

a keypad module comprising a plurality of switches disposed within the wireless telecommunication device so as to be actuatable upon any of the plurality of depressible keys being pressed.

20. The wireless telecommunication device of claim 19, wherein the wireless telecommunication device comprises a mobile radiotelephone, further wherein the plurality of depressible keys comprise a mobile radiotelephone keypad interface.
