Abstract

An electronic device may include a flexible display including a first window, and a polymer layer disposed on the first window to overlap at least a partial area of the first window and having a pattern formed on at least a partial area of the surface oriented in a direction away from the surface facing the first window, wherein each of the first window, the flexible display, and the polymer layer comprises a deformation part corresponding to a deformation axis and a planar part which is disposed on at least one side with reference to the deformation part, and the pattern may comprise a recess pattern formed in the lengthwise direction of the deformation axis in the deformation part of the polymer layer. In addition, various embodiments are possible.

Claims (32)

1 . An electronic device comprising:

a flexible display panel;

a first window over the flexible display panel; and

a polymer based layer, comprising a polymer, disposed over the first window to overlap at least a partial area of the first window and comprising a pattern formed on at least a partial area of a surface facing a direction opposite to a surface facing the first window,

wherein each of the first window, the flexible display panel, and the polymer based layer comprises a deformation portion corresponding to a deformation axis and a planar portion disposed on at least one side based on the deformation portion, and

wherein the pattern comprises a recess pattern formed in a lengthwise direction of the deformation axis on the partial area of the surface facing the direction opposite to the surface facing the first window.

2 . The electronic device of claim 1 , wherein the polymer based layer is hardened and/or cured by at least one of ultraviolet (UV) light and heat.

3 . The electronic device of claim 1 , wherein the pattern is formed by UV molding.

4 . The electronic device of claim 1 , wherein the pattern comprises an uneven pattern formed on at least a portion of the planar portion of the polymer based layer.

5 . An electronic device comprising:

a flexible display panel;

a first window over the flexible display panel; and

a polymer based layer, comprising a polymer, disposed on the first window to overlap at least a partial area of the first window and comprising a pattern formed on at least a partial area of a surface facing a direction opposite to a surface facing the first window,

wherein each of the first window, the flexible display panel, and the polymer based layer comprises a deformation portion corresponding to a deformation axis and a planar portion disposed on at least one side based on the deformation portion,

wherein the pattern comprises a recess pattern formed in a lengthwise direction of the deformation axis in the deformation portion of the polymer based layer,

wherein the pattern comprises an uneven pattern formed on at least a portion of the planar portion of the polymer based layer, and wherein the uneven pattern is excluded from a partial area of the planar portion of the polymer based layer corresponding to an area of the electronic device in which a sensor is disposed.

6 . The electronic device of claim 1 , wherein the pattern comprises an uneven pattern formed on at least a portion of the deformation portion of the polymer based layer.

7 . The electronic device of claim 1 , wherein a surface of the first window facing the polymer based layer is flat across the planar portion and the deformation portion of the first window.

8 . The electronic device of claim 1 , wherein a surface of the polymer based layer facing the first window is flat across the planar portion and the deformation portion of the polymer based layer.

9 . The electronic device of claim 1 , wherein a surface of the first window facing the polymer based layer comprises a recess corresponding to the recess pattern, and the recess is at least partially filled with a transparent polymer.

10 . An electronic device comprising:

a first structure comprising a slide;

a second structure comprising at least part of a housing, the first and/or second structure configured to be movable relative to the other;

a flexible display comprising a window;

a polymer based layer disposed on the window to overlap at least a partial area of the window and comprising a pattern formed on at least a partial area of a surface facing a direction opposite to a surface facing the window; and

a housing decoration configured to cover at least a portion of the window, the housing decoration comprising a receiving groove formed by recessing a surface facing the window inward,

wherein each of the window, the flexible display, and the polymer based layer comprises a planar portion, a deformation portion that is partially received inside the second structure based on sliding movement of the first structure, and a side portion that extends in a direction perpendicular to a sliding direction from the planar portion and the deformation portion, and

wherein the pattern comprises a recess pattern that is formed in the sliding direction in the deformation portion of the polymer based layer, and a protrusion pattern that protrudes from a surface facing a direction opposite to a surface facing the window to be inserted into the receiving groove in the side portion of the polymer based layer.

11 . The electronic device of claim 10 , wherein the polymer based layer is hardened and/or cured by at least one of ultraviolet (UV) light and heat.

12 . The electronic device of claim 10 , wherein the pattern is formed by UV molding.

13 . The electronic device of claim 10 , wherein the pattern comprises an uneven pattern formed on at least a portion of the planar portion of the polymer based layer.

14 . The electronic device of claim 10 , wherein the pattern comprises an uneven pattern formed on at least a portion of the deformation portion of the polymer based layer.
