Abstract

Claims (77)

1 . A flexible transparent member comprising:

a first glass portion having a first thickness;

a second glass portion having a second thickness that is thinner than the first thickness; and

at least one resin portion,

wherein an upper surface of the second glass portion is recessed in a downward direction with respect to an upper surface of the first glass portion and forms an upper recess,

wherein a lower surface of the second glass portion is recessed in an upward direction with respect to a lower surface of the first glass portion and forms a lower recess,

wherein the at least one resin portion is respectively disposed in at least one of the upper recess or the lower recess,

wherein the first glass portion is chemically reinforced inward from the upper surface and the lower surface of the first glass portion by a first depth,

wherein the second glass portion is chemically reinforced inward from the upper surface and the lower surface of the second glass portion by a second depth,

wherein the first depth has a length of 5% to 20% of a thickness of the first glass portion, and

wherein the second depth has a length of 5% to 20% of a thickness of the second glass portion.

2 . The flexible transparent member of claim 1 ,

wherein the first glass portion and the second glass portion are formed to be horizontally symmetrical.

3 . The flexible transparent member of claim 1 ,

wherein a first ratio of the first depth to the first thickness is substantially same as a second ratio of the second depth to the second thickness.

4 . The flexible transparent member of claim 1 ,

wherein the first glass portion is chemically reinforced based on a first chemical reinforcement process,

wherein the second glass portion is chemically reinforced based on a second chemical reinforcement process, and

wherein the first chemical reinforcement process is different than the second chemical reinforcement process.

5 . A flexible display comprising:

a display panel; and

a transparent member disposed on the display panel,

wherein the transparent member includes:

a first glass portion having a first thickness, and

a second glass portion having a second thickness that is thinner than the first thickness,

wherein an upper surface of the second glass portion is recessed in a direction toward the display panel with respect to an upper surface of the first glass portion,

wherein a lower surface of the second glass portion is recessed in an opposite direction to the display panel with respect to a lower surface of the first glass portion,

wherein the first glass portion is chemically reinforced inward from the upper surface and the lower surface of the first glass portion by a first depth,

wherein the second glass portion is chemically reinforced inward from the upper surface and the lower surface of the second glass portion by a second depth,

wherein the first depth has a length of 5% to 20% of a thickness of the first glass portion, and

wherein the second depth has a length of 5% to 20% of a thickness of the second glass portion.

6 . The flexible display of claim 5 ,

wherein the first depth is greater than the second depth.

7 . The flexible display of claim 5 ,

wherein a first ratio of the first depth to the first thickness is substantially same as a second ratio of the second depth to the second thickness.

8 . The flexible display of claim 5 ,

wherein the second glass portion has a stepped shape with respect to the first glass portion.

9 . The flexible display of claim 5 ,

wherein the transparent member further includes a third glass portion formed to be sloped to connect the first glass portion and the second glass portion.

10 . The flexible display of claim 5 ,

wherein the second glass portion has a penetrated portion.

11 . The flexible display of claim 5 ,

wherein at least one of the upper surface or the lower surface of the second glass portion has a pattern in which a concave portion and a convex portion are alternately disposed.

12 . The flexible display of claim 11 ,

wherein a boundary between the concave portion and the convex portion is formed by a vertical step.

13 . The flexible display of claim 11 ,

wherein the pattern in which the concave portion and the convex portion are alternately disposed has a wave-shaped cross section.

14 . The flexible display of claim 5 ,

wherein the second glass portion is formed to be symmetrical with respect to a virtual plane that divides a thickness of the transparent member in half.

15 . The flexible display of claim 5 ,

wherein the first glass portion is chemically reinforced based on a first chemical reinforcement process,

wherein the second glass portion is chemically reinforced based on a second chemical reinforcement process, and

wherein the first chemical reinforcement process is different than the second chemical reinforcement process.

16 . An electronic device comprising:

a housing including a first housing and a second housing;

a hinge module connected with the first housing and the second housing; and

a flexible display at least partially received in the first housing and the second housing,

wherein the flexible display includes:

a display panel, and

a transparent member arranged on the display panel,

wherein the transparent member includes:

a first glass portion having a first thickness, and

a second glass portion having a second thickness that is thinner than the first thickness,

wherein an upper surface of the second glass portion is recessed in a direction toward the display panel with respect to an upper surface of the first glass portion,

wherein a lower surface of the second glass portion is recessed in an opposite direction to the display panel with respect to a lower surface of the first glass portion,

wherein the first glass portion is chemically reinforced inward from the upper surface and the lower surface of the first glass portion by a first depth,

wherein the second glass portion is chemically reinforced inward from the upper surface and the lower surface of the second glass portion by a second depth,

wherein the first depth has a length of 5% to 20% of a thickness of the first glass portion, and

wherein the second depth has a length of 5% to 20% of a thickness of the second glass portion.

17 . The electronic device of claim 16 ,

wherein the second glass portion is formed to be symmetrical with respect to a virtual plane that divides a thickness of the transparent member in half.

18 . The electronic device of claim 16 ,

wherein a first ratio of the first depth to the first thickness is substantially same as a second ratio of the second depth to the second thickness.

19 . The electronic device of claim 16 ,

wherein the first glass portion is chemically reinforced based on a first chemical reinforcement process,

wherein the second glass portion is chemically reinforced based on a second chemical reinforcement process, and

wherein the first chemical reinforcement process is different than the second chemical reinforcement process.
