Abstract
A window module includes a base film being optically clear and a window protection layer disposed on the base film. The window protection layer includes a barrier layer disposed on the base film, an impact absorbing layer disposed between the base film and the barrier layer, and a first impact transmitting layer disposed between the barrier layer and the impact absorbing layer. A modulus of the impact absorbing layer is less than a modulus of the barrier layer, and the first impact transmitting layer includes graphene or carbon nanotubes.
Claims15
A window module comprising:
- a base film being optically clear;
- and
- a window protection layer disposed on the base film, the window protection layer including:
- a barrier layer disposed on the base film;
- an impact absorbing layer disposed between the base film and the barrier layer;
- a first impact transmitting layer disposed between the barrier layer and the impact absorbing layer;
- and
- a second impact transmitting layer disposed between the impact absorbing layer and the base film,
- wherein a modulus of the impact absorbing layer is less than a modulus of the barrier layer, and the first and second impact transmitting layers includes graphene or carbon nanotubes,
- wherein the modulus of the barrier layer is about 2 gigapascals or more and about 8 gigapascals or less,
- wherein the modulus of the impact absorbing layer is about 300 megapascals or more and about 1.5 gigapascals or less, and
- wherein another barrier layer is not disposed between the base film and the barrier layer.
An electronic device comprising:
- a display device comprising:
- a display panel;
- and
- a window module including:
- a base film disposed on the display panel;
- and
- a window protection layer disposed on the base film, the window protection layer including:
- a barrier layer;
- a first impact transmitting layer;
- an impact absorbing layer;
- and
- a second impact transmitting layer disposed between the base film and the impact absorbing layer sequentially disposed toward the base film in a thickness direction,
- wherein a modulus of the impact absorbing layer is less than a modulus of the barrier layer, and
- wherein the first and second impact transmitting layers includes graphene or carbon nanotubes,
- wherein the modulus of the barrier layer is about 2 gigapascals or more and about 8 gigapascals or less, and the modulus of the impact absorbing layer is about 300 megapascals or more and about 1.5 gigapascals or less, and
- wherein another barrier layer is not disposed between the base film and the barrier layer.
