an opaque masking layer applied to a perimeter of at least one of said front and rear faces of said front screen panel so as to define a masked perimeter area framing a viewable area of said screen assembly; and

at least one touch control operatively coupled to at least one of said front and rear faces of said front screen panel in said masked perimeter area.

2. The television assembly of claim 1, wherein said at least one touch control operatively coupled to said front screen panel comprises a touch sensor attached to the rear face of the front screen panel.

3. The television assembly of claim 2, wherein said touch sensor is adhesively attached.

4. The television assembly of claim 1, further comprising indicia identifying at least one of a location and a function of said at least one touch screen control provided on at least one of said front and rear faces of said front screen panel and visible from a front of said screen assembly.

5. The television assembly of claim 4, wherein said indicia comprises at least one of text and artwork indicating the location and function of the touch control.

6. The television assembly of claim 4, wherein said masking layer is applied to said rear face of said front screen panel and wherein said indicia is provided on said rear face prior to applying said masking layer.

7. The television assembly of claim 2, wherein said masking layer is applied to said rear face of said front screen panel and the touch sensor is attached to said rear face after applying said masking layer.

8. The television assembly of claim 1, wherein the front screen panel is formed from glass.

9. The television assembly of claim 1, wherein said masking layer is silk screened to a perimeter of the rear face of the front screen panel to define said masked perimeter area.

10. The television assembly of claim 1, wherein said front screen panel has a length and width greater than a length and width of said housing so that said front screen panel projects beyond said housing.

11. The television assembly of claim 1, wherein the front screen panel is flat.

12. The television assembly of claim 1, wherein said front face is substantially coextensive to said rear face.

13. The television assembly of claim 1, wherein the television assembly is one of a plasma television, an LCD television, and a projection television.

14. In a television assembly, a screen assembly comprising:

a generally flat front screen panel having a front face and a rear face;

an opaque masking layer applied to a perimeter of at least one of said front and rear faces of said front screen panel so as to define a masked perimeter area framing a viewable area of said screen assembly; and

at least one touch control operatively coupled to at least one of said front and rear faces of said front screen panel in said masked perimeter area.

15. The assembly of claim 14, wherein said at least one touch control operatively coupled to said front screen panel comprises a touch sensor attached to the rear face of the front screen panel.

16. The assembly of claim 15, wherein said touch sensor is adhesively attached.

17. The assembly of claim 15, wherein said masking layer is applied to said rear face of said front screen panel and the touch sensor is attached to said rear face after applying said masking layer.

18. The assembly of claim 14, wherein the front screen panel is formed from glass.

19. The assembly of claim 14, wherein said masking layer is silk screened to a perimeter of the rear face of the front screen panel to define said masked perimeter area.

20. The assembly of claim 14, further comprising indicia identifying at least one of a location and a function of said at least one touch screen control provided on at least one of said front and rear faces of said front screen panel and visible from a front of said screen assembly.
