Card with digital display
The invention relates to a card ( 38 ) including a digital display ( 10 ) arranged in a node ( 4 ) defining the central portion of the card. It further comprises a plastic layer ( 40 ) the major portion ( 42 ) of which is opaque, and a transparent display portion ( 44 ). A pattern ( 14 ) is printed on the upper face of the plastic layer ( 40 ), in particular by an offset printing technique. The plastic layer ( 40 ) is covered with a transparent film ( 12 ) attached thereto by a thin glue layer ( 34 ) defining an adhesion interface. The electronic display ( 10 ) is fully integrated in the card ( 38 ) and the printed pattern ( 14 ) exhibits a good contrast on the opaque portion of said plastic layer. Furthermore, a good adhesion is obtained between all the layers of the card.
1. A card including an electronic display arranged in a core of said the card, wherein the card has a plastic layer above the core, wherein the plastic layer is formed of two parts, and wherein the two parts are
(a) an opaque greater part that is a preformed opaque plastic sheet with an aperture; and
(b) a transparent display part located above the electronic display and, made of a transparent material, wherein the transparent display part is arranged in the aperture of the opaque plastic sheet.
2. The card according to claim 1 , comprising a transparent external film arranged on the plastic layer, wherein a pattern is printed on the opaque greater part of the plastic layer, on the side of the transparent external film or on the interior surface of the transparent external film, so that the printed pattern is located opposite the opaque greater part.
3. The card according to claim 2 , wherein a layer of resin or adhesive is arranged between the electronic display and the transparent display part of the plastic layer.
4. The card according to claim 2 , wherein an adhesive layer is provided between the plastic layer and the transparent external film.
5. The card according to claim 1 , wherein the thickness of the plastic layer is approximately constant.
6. The card according to claim 1 , wherein the plastic layer is covered by a transparent external film.
7. The card according to claim 1 , wherein a layer of resin or adhesive is arranged between the electronic display and the transparent display part of the plastic layer.
8. The card according to claim 1 , wherein the transparent display part has a magnifying effect.
9. The card according to claim 8 , wherein the display part defines a Fresnel lens.
10. The card according to claim 1 , wherein the opaque plastic sheet is covered by a transparent external film.
11. The card according to claim 10 , wherein the display part of the plastic layer is formed by a transparent plate arranged in the aperture of the opaque plastic sheet.
12. The card according to claim 11 , wherein an adhesive layer is provided between the opaque plastic sheet with the transparent plate and the transparent external film.
13. The card according to claim 10 , wherein the transparent material forming the display part of the plastic layer is injected into the aperture of the opaque plastic sheet.
14. The card according to claim 1 , wherein a layer of resin or adhesive is arranged between the electronic display and the transparent display part of the opaque plastic sheet.
15. The card according to claim 1 , wherein the plastic layer is directly arranged on the top surface of said core.
16. The card according to claim 15 , where the core is formed by a resin, and wherein an electronic unit and the electronic display are embedded in the resin.
17. The card according to claim 16 , wherein the resin is transparent and covers the electronic display.
18. The card according to claim 15 , wherein the electronic display at the top surface thereof is flush with the top surface of said core.
19. The card according to claim 1 , wherein the plastic layer and the core are assembled by means of a thin adhesive layer.
20. The card according to claim 19 , where the core is formed by a resin, and wherein an electronic unit and the electronic display are embedded in the resin.
21. The card according to claim 20 , wherein the resin is transparent and covers the electronic display.
22. The card according to claim 19 , wherein the electronic display at the top surface thereof is flush with the top surface of said core.
23. The card according to claim 1 , wherein the display part of the plastic layer is formed by a transparent plate arranged in the aperture of the opaque plastic sheet.
24. The card according to claim 1 , wherein the display part of the plastic layer is formed by a transparent plate arranged in the aperture of the opaque plastic sheet.
