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 vehicle interior system comprising
a base having a curved surface defining an opening;
a curved glass substrate disposed within the opening, the curved 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 surface orthogonal to both the thickness and the width, and wherein the thickness is 1.5 mm or less, and wherein the second major surface comprises a first radius of curvature of 60 mm or greater; and
a display module attached to the second major surface and comprising a second radius of curvature,
a frame comprising a curved support surface;
an adhesive layer joining the curved support surface of the frame to the second major surface of the curved glass substrate;
wherein the first radius of curvature is within 10% of one of or both the radius of curvature of the curved surface and the second radius of curvature; and
wherein the adhesive layer maintains the curved glass substrate in a cold-bent configuration on the curved support surface of the frame.

2. The vehicle interior system 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.

3. The vehicle interior system of claim 1 , wherein the curved glass substrate is strengthened.

4. The vehicle interior system of claim 1 , wherein the display module comprises a second glass substrate and a backlight unit, wherein the second glass substrate is disposed adjacent the second major surface and between the backlight unit and the second major surface, and wherein the backlight unit is optionally curved to exhibit the second radius of curvature.

5. The vehicle interior system of claim 4 , wherein the second glass substrate comprises a curved second glass substrate that is optionally cold-bent.

6. The vehicle interior system of claim 5 , wherein the frame at least partially surrounding the backlight unit, at least partially surrounds the second glass substrate, or at least partially surrounds the minor surface of the glass substrate.

7. The vehicle interior system of claim 1 , wherein either one of or both the first major surface and the second major surface comprises a surface treatment.

8. The vehicle interior system of claim 1 , further comprising touch functionality.

9. The vehicle interior system of claim 1 , wherein the base comprises any one of a center console, a dashboard, an arm rest, a pillar, a seat back, a floor board, a headrest, a door panel, and a steering wheel.

10. A kit comprising:
a curved 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 wherein the second major surface comprises a first radius of curvature; and
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 using an adhesive material that maintains the curved glass substrate in a cold bend configuration against the curved surface of the frame.

11. The kit of claim 10 , wherein the first radius of curvature is 250 nm 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.

12. The kit of claim 10 , wherein the curved glass substrate is cold-bent.

13. The kit of claim 10 , further comprising a display module, a touch panel, or a display module and a touch panel, wherein the display module, the touch panel, or the display module and the touch panel are coupled to the second major surface of the curved glass substrate.

14. The kit of claim 13 , wherein the display module comprises a display and a back-light unit, and the display comprises a second glass substrate that is curved, and wherein the second glass substrate comprises a display surface having a second radius of curvature that is within 10% of the first radius of curvature.

15. The kit of claim 14 , wherein the second glass substrate is attached to the second major surface or the frame.

16. The kit of claim 13 , wherein the display module comprises a display and a back-light unit, and wherein the display 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.

17. The kit of claim 16 , wherein the second glass substrate comprises an adhesive layer for attachment to the curved glass substrate or the frame.

18. The kit of claim 17 , wherein the second glass substrate is cold-bent to the second radius of curvature and attached to the curved glass substrate or the frame.

19. The kit of claim 13 , wherein the frame is removably coupled to the second major surface of the curved glass substrate.

20. The vehicle interior system of claim 7 , wherein the surface treatment comprises at least one of an easy-to-clean surface, an anti-glare surface, an anti-reflective surface, a haptic surface, or a decorative surface.

21. The vehicle interior system of claim 20 , wherein the surface treatment comprises the decorative surface and wherein the decorative surface comprises an aesthetic design formed from a pigment.

22. The vehicle interior system of claim 21 , wherein the aesthetic design comprises at least one of a wood-grain design, a brushed metal design, a graphic design, a portrait, or a logo.

23. The vehicle interior system of claim 20 , wherein the decorative surface masks the display module from a viewer when the display module is turned off and wherein the decorative surface permits the display module to be viewed when the display is turned on.

24. The kit of claim 10 , wherein either one of or both the first major surface and the second major surface comprises a surface treatment and wherein the surface treatment comprises at least one of an easy-to-clean surface, an anti-glare surface, an anti-reflective surface, a haptic surface, or a decorative surface.
