Abstract
Embodiments of this disclosure pertain to a laminate including a first substrate, an interlayer and a light responsive material disposed on the first substrate, and a second substrate disposed on the interlayer. The laminate may be complexly curved. The light responsive material may include any one or more of an electrochromic material, a photochromic material, a suspended particle material, a micro-blind material and a liquid crystal material. In one or more embodiments, the laminate comprises a display unit disposed between the first and second substrate. Methods for forming the laminate are also disclosed.
Claims20
A laminate comprising
- a first substrate;
- an interlayer disposed on the first substrate;
- and
- a second substrate disposed on the interlayer,
- wherein the laminate is complexly curved and comprises, as two separate components:
- a light responsive material;
- and
- a display unit.
A laminate comprising:
- a complexly curved first substrate;
- a substantially planar second substrate;
- at least one interlayer intermediate the first substrate and the second substrate;
- a display unit;
- and
- at least one light responsive material that is separate from the display unit,
- wherein the second substrate is cold formed to the curvature of the first substrate, and
- wherein the light responsive material is disposed between the first substrate and the second substrate or integral to one or both the first substrate and the second substrate.
A method of cold forming a laminate comprising:
- laminating a complexly curved first substrate and a substantially planar second substrate together at a temperature less than the softening temperature of the first and second substrates to provide a complexly curved second substrate;
- and
- laminating the complexly curved first substrate and complexly curved second substrate to at least one polymer interlayer that is disposed between the first and second substrate to provide a complexly curved laminate,
- wherein complexly curved laminate comprises, as two separate components:
- a light responsive material;
- and
- a display unit.
