Abstract

Embodiments of a vehicle interior system are disclosed. In one or more embodiments, the system includes a base with a curved surface, and a display or touch panel disposed on the curved surface. The display includes a cold-bent glass substrate with a thickness of 1.5 mm or less and a first radius of curvature of 20 mm or greater, and a display module and/or touch panel attached to the glass substrate having a second radius of curvature that is within 10% of the first radius of curvature. Methods for forming such systems are also disclosed.

First claim

What is claimed is:

1. A kit comprising:
a flexible and cold-formable cover glass substrate that comprises a first major surface, a second major surface opposing the first major surface and a minor surface connecting the first major surface and the second major surface, a thickness defined as a distance between the first major surface and the second major surface, a width defined as a first dimension of one of the first or second major surfaces orthogonal to the thickness, and a length defined as a second dimension of one of the first or second major surfaces orthogonal to both the thickness and the width, and wherein the thickness is 1.5 mm or less; and
a curved display module or curved touch panel having a first radius of curvature;
wherein the cover glass substrate is chemically strengthened or thermally strengthened;
wherein one or both the first major surface and the second major surface of the first cold-formed cover glass substrate comprises a surface treatment comprising any one of an easy-to-clean surface, an anti-glare surface, an anti-reflective surface, a haptic surface, and a decorative surface, and
wherein the display or touch panel comprises a second glass substrate that is substantially flat and is cold-bendable to a second radius of curvature that is within 10% of the first radius of curvature.

2. The kit of claim 1 , wherein the first radius of curvature is 20 mm or greater, and, wherein the width is in a range from about 5 cm to about 250 cm, and the length is from about 5 cm to about 250 cm.

3. The kit of claim 1 , wherein the curved display module comprises an OLED display.

5. The kit of claim 1 wherein the display comprises a second glass substrate that is curved.

6. The kit of claim 1 , wherein the touch panel comprises a second glass substrate that is curved.

7. The kit of claim 1 , further comprising a removable frame having a curved surface having the first radius of curvature, wherein the curved surface is removably coupled to the second major surface of the cover glass substrate.

8. The kit of claim 1 , further comprising a frame having a curved surface having the first radius of curvature, wherein the curved surface is coupled to the second major surface of the curved glass substrate.

9. The kit of claim 1 , wherein the thickness is greater than 0.3 mm.

10. The kit of claim 1 , wherein the width is in a range from about 5 cm to about 250 cm, and the length is from about 5 cm to about 250 cm.

11. The kit of claim 1 , wherein the second major surface comprises an adhesive.

12. A cover glass assembly comprising:
a first cold-formed curved cover glass substrate comprising a first major surface, a second major surface opposing the first major surface and a minor surface connecting the first major surface and the second major surface, a thickness defined as a distance between the first major surface and the second major surface, a width defined as a first dimension of one of the first or second major surfaces orthogonal to the thickness, and a length defined as a second dimension of one of the first or second major surfaces orthogonal to both the thickness and the width, wherein the second major surface comprises a first radius of curvature;
a second curved cover glass substrate comprising a first major surface, a second major surface opposing the first major surface for attachment to a display or touch panel and a minor surface connecting the first major surface, wherein the second major surface has a second radius of curvature; and
