Abstract
A flexible display device includes: a bendable display panel; a protective layer on a surface of the display panel; and an elastic layer on the first surface of the protective layer. The protective layer has a groove in a first surface thereof, and the elastic layer is in the groove in the protective layer.
Claims20
A flexible display device comprising:
- a bendable display panel;
- a protective layer on a surface of the display panel, the protective layer having a groove in a first surface of the protective layer;
- and
- an elastic layer on the first surface of the protective layer and in the groove in the protective layer.
1 more element
A flexible display device comprising:
- a bendable display panel;
- a first elastic layer on a surface of the display panel;
- a second elastic layer on the first elastic layer, the second elastic layer having a greater elastic strain energy than the first elastic layer;
- and
- a mixed layer between the first and second elastic layers, the mixed layer comprising a material of the first elastic layer and a material of the second elastic layer.
2 more elements
A method of manufacturing a flexible display device, the method comprising:
- applying nanoparticles to a protective layer forming material;
- forming a protective layer by curing the protective layer forming material;
- defining grooves in a first surface of the protective layer by vaporizing the nanoparticles in the protective layer;
- applying an elastic layer forming material on the first surface of the protective layer at where the grooves are formed;
- and
- forming an elastic layer by curing the elastic layer forming material.
3 more elements
A method of manufacturing a flexible display device, the method comprising:
- applying a first elastic layer forming material on a surface of a bendable display panel;
- partially curing the first elastic layer forming material;
- applying a second elastic layer forming material on the partially-cured first elastic layer forming material;
- and
- fully curing the first elastic layer forming material to form a first elastic layer and the second elastic layer forming material to form a second elastic layer, the second elastic layer having a greater elastic strain energy than the first elastic layer.
