Capacitive touch screen formed by injection compression molding
According to one or more embodiments, a polymeric article includes a first polymeric layer defining a first portion and a second portion, the first portion having a first side and a second side opposing the first side, the first side being exposed to atmospheric air, and an ink layer and a second polymeric layer, the ink layer being positioned between the second polymeric layer and the second portion of the first polymeric layer.
1. A capacitive touch-screen comprising:
a first polymeric layer defining first and second portions each having a first side exposed to air and a second side opposing the first side;
a second polymeric layer arranged on the second side of the first and second portions and in direct contact with the first portion; and
a conductive ink layer arranged between and in contact with the second side of the second portion and the second polymeric layer.
2. The capacitive touch-screen of claim 1 , wherein the first portion is ink-layer-free.
3. The capacitive touch-screen of claim 1 , wherein the first and second portions of the first polymeric layer are positioned next to each other along a longitudinal axis of the first polymeric layer.
4. The capacitive touch-screen of claim 1 , wherein at least one of the first and second polymeric layers includes polycarbonate.
5. The capacitive touch-screen of claim 1 , wherein the first portion has a surface linear dimension of greater than 2 centimeters.
6. The capacitive touch-screen of claim 1 , wherein the ink layer comprises a circuit board.
7. The capacitive touch-screen of claim 1 , wherein the second polymeric layer includes a first sub-layer and a second sub-layer chemically different from the first sub-layer, the first sub-layer being positioned between the ink layer and the second sub-layer.
8. The capacitive touch-screen of claim 7 , wherein the first sub-layer is lighter in color than the second sub-layer.
9. The capacitive touch-screen of claim 7 , wherein the first sub-layer comprises polycarbonate and the second sub-layer includes a polymer other than polycarbonate.
10. A polymeric article comprising:
a first polymeric layer of optical grade and defining a first portion and second portions each having a first side and a second side opposing the first side;
a second polymeric layer arranged on the second side of the first and second portions and in direct contact with the first portion; and
an electronically conductive ink layer arranged between and in contact with the second side of the second portion and the second polymeric layer,
wherein the article is a capacitive touch article.
11. The polymeric article of claim 10 , wherein the first and second portions of the first polymeric layer are positioned next to each other along a longitudinal axis of the first polymeric layer.
12. The polymeric article of claim 10 , wherein the second polymeric layer includes a first sub-layer and a second sub-layer chemically different from the first sub-layer, the first sub-layer being positioned between the ink layer and the second sub-layer.
13. The polymeric article of claim 12 , wherein the first sub-layer comprises polycarbonate and the second sub-layer includes a polymer other than polycarbonate.
14. The capacitive touch-screen of claim 1 , wherein the first and second portions are in material continuity.
15. The capacitive touch-screen of claim 1 , wherein the article comprises more than one first and second portions such that a plurality of first and second portions alternate.
16. The capacitive touch-screen of claim 2 , wherein the ink layer is free of contact with the second side of the first polymeric layer.
