Display device
View Patent ↗A flexible foil having double-sided conductor patterns of a satisfactorily conducting material (gold, silver, nickel) is used in the interconnection of conductor patterns of a display device (LCD, OLED), which enhances the freedom of design.
1. A display device comprising a first substrate having a conductor pattern for electrically connecting pixels, and having a laminar substrate with opposed sides, which opposed sides are both provided with electrically conducting patterns that are electrically through-connected via at least one opening in the laminar substrate, wherein said at least one opening is proximate said pixels.
2. The display device of claim 1 , wherein said electrically conducting patterns are metal patterns.
3. The display device of claim 2 , wherein said metal patterns are formed from metals chosen from a group of gold, silver and nickel.
4. The display device of claim 1 , wherein said conductor pattern on said first substrate is connected to an electrically conducting pattern on said laminar substrate at an area of a through-connection.
5. The display device of claim 4 , wherein the part of said laminar substrate provided with said through-connections is secured to said first substrate.
6. The display device of claim 4 , wherein at least one of said electrically conducting patterns contacts a conductor pattern on a further support.
7. The display device of claim 1 , wherein said laminar substrate is flexible.
8. The display device of claim 1 , wherein electrically conducting patterns realized on both sides of said laminar substrate form a cross-section.
9. The display device of claim 1 , wherein said display device has a second substrate and an electro-optical material between said first and second substrates, each provided with picture electrodes defining pixels together with said electro-optical material.
10. The display device of claim 1 , wherein said display device comprises an electroluminescent material.
