Abstract
The present invention provides a cover window including a first region having a first stiffness; a second region having a second stiffness being greater than the first stiffness; and a nano-particle in a boundary between the first and second regions.
Claims19
A cover window, comprising:
- a first region having a first stiffness;
- a second region having a second stiffness greater than the first stiffness, the second region including a first portion and a second portion, wherein the first portion is closer to the first region than the second portion;
- and
- a nano-particle in the first portion and not in the second portion,
- wherein the first region has a first thickness, and the nano-particle is positioned within the first region at a second thickness smaller than the first thickness.
2 more elements
A cover window, comprising:
- a first region having a first stiffness and including a pattern region and a non-pattern region at a periphery of the pattern region;
- a second region having a second stiffness greater than the first stiffness;
- and
- a nano-particle in the first region,
- wherein the nano-particle has a first density in the pattern region and a second density in the non-pattern region, and the first density is different from the second density,
- wherein the cover window has a single-layered structure,
- wherein the first region has a first thickness, and the nano-particle is positioned within the first region at a second thickness smaller than the first thickness.
4 more elements
A foldable display device, comprising:
- a display panel;
- and
- a cover window on a display side of the display panel, the cover window including:
- a first region having a first stiffness;
- a second region having a second stiffness greater than the first stiffness, the second region including a first portion and a second portion, wherein the first portion is closer to the first region than the second portion;
- and
- a nano-particle in the first portion and not in the second portion,
- wherein the cover window has a single-layered structure,
- wherein the first region has a first thickness, and the nano-particle is positioned within the first region at a second thickness smaller than the first thickness.
