Abstract

Embodiments of a dynamically bendable automotive interior display system are disclosed. In one or more embodiments, the system includes a display, a dynamically bendable cover substrate assembly disposed over the display, wherein the cover substrate assembly comprises a cover substrate with a bend axis, and a reversible support attached to at least a portion the cover substrate that dynamically bends the cover substrate along the bend axis in a cycle from a first radius of curvature to a second radius of curvature and from the second radius of curvature to the first radius of curvature. In one or more embodiments, the system includes one or more frames that partially house the display and are attached to the cover substrate.

First claim

What is claimed is:

1. A dynamically bendable cover substrate comprising:
a first major surface, 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, 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 a bend axis,
wherein the cover substrate is dynamically bendable around the bend axis in a repeating cycle from a first radius of curvature to a second radius of curvature and from the second radius of curvature to the first radius of curvature; and
wherein, when an impactor having a mass of 6.8 kg impacts the first major surface at an impact velocity of 5.35 m/s to 6.69 m/s, the deceleration of the impactor is 120 g (g-force) or less.

2. A display system comprising:
a display;
a dynamically bendable cover substrate assembly disposed over the display;
wherein the dynamically bendable cover substrate assembly comprises
a cover substrate having a first major surface, 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, 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 a bend axis; and
a reversible support attached to at least a portion of the second major surface of the cover substrate that dynamically bends the cover substrate around the bend axis in a repeating cycle from a first radius of curvature to a second radius of curvature and from the second radius of curvature to the first radius of curvature;
wherein the dynamically bendable cover substrate is capable of being dynamically bent along the bend axis for more than 100 cycles without delamination between the dynamically bendable cover substrate and the display.

3. The display system of claim 2 , wherein the first radius of curvature is about 10,000 mm or less.

4. The display system of claim 3 , wherein the cover substrate comprises a cold-bent glass article or a hot-formed glass article.
