Abstract

A display apparatus includes a first base plate, a second base plate coupled to the first base plate to allow the second base plate to be rotated on the basis of a rotation axis between the first base plate and the second base plate, a moving plate coupled to the second base plate and configured to slide along a first direction with respect to the second base plate, a pop-up plate configured to move along a second direction corresponding to a thickness direction of the second base plate on the second base plate in accordance with a movement of the moving plate, and a display panel including a first portion coupled to the first base plate and a second portion coupled to the moving plate.

First claim

What is claimed is:

1. A display apparatus comprising:
a first base plate;
a second base plate coupled to the first base plate to allow the second base plate to be rotated on the basis of a rotation axis between the first base plate and the second base plate;
a moving plate coupled to the second base plate and configured to slide along a first direction with respect to the second base plate;
a pop-up plate configured to move along a second direction corresponding to a thickness direction of the second base plate on the second base plate in accordance with a movement of the moving plate; and
a display panel comprising a first portion coupled to the first base plate and a second portion coupled to the moving plate;
wherein the pop-up plate comprises:
a first upper surface having a width corresponding to a first length along the first direction;
a first bottom surface facing the first upper surface and having a width corresponding to a second length greater than the first length along the first direction;
three first side surfaces substantially perpendicular to the first upper surface and connecting the first upper surface and the first bottom surface; and
a first inclined surface connecting the first upper surface and the first bottom surface.

2. The display apparatus of claim 1 , further comprising an elastic member between the pop-up plate and the second base plate.

3. The display apparatus of claim 2 , wherein the second base plate comprises a first groove configured to accommodate the elastic member, and
wherein the pop-up plate comprises a second groove configured to accommodate the elastic member.

4. The display apparatus of claim 1 , wherein the moving plate comprises:
a base portion coupled to the second portion;
a first wing portion protruding from a first side surface of the base portion; and
a second wing portion protruding from a second side surface of the base portion, the first wing portion and the second wing portion being spaced apart from each other along a third direction crossing the first direction, and
wherein the second base plate has an accommodating portion configured to accommodate the wing portion.

5. The display apparatus of claim 1 , wherein the first length is equal to or greater than a value obtained by multiplying a shortest distance between the rotation axis and the display panel by pi (r).

6. The display apparatus of claim 1 , wherein the moving plate comprises:
a second upper surface coupled to the second portion and having a width corresponding to a third length along the first direction;
a second bottom surface facing the second upper surface and having a width corresponding to a fourth length smaller than the third length along the first direction;
three second side surfaces substantially perpendicular to the second upper surface and connecting the second upper surface and the second bottom surface; and
a second inclined surface connecting the second upper surface and the second bottom surface, and a first angle between the first inclined surface and the first bottom surface is substantially equal to a second angle between the second inclined surface and the second upper surface.

7. The display apparatus of claim 1 , wherein a corner at which one side surface among the first side surfaces, which faces the first inclined surface, is connected to the first bottom surface has a round shape.

8. The display apparatus of claim 1 , wherein the second base plate comprises:
a bottom portion, the pop-up plate and the moving plate being on the bottom portion; and
a sidewall portion extending in the second direction from the bottom portion, the bottom portion comprising a stepped portion defined therein to accommodate the pop-up plate.

9. The display apparatus of claim 8 , wherein the second base plate further comprises a protrusion portion protruding from an inner surface of the sidewall portion and the first upper surface of the pop-up plate comprises a recess formed therein to accommodate the protrusion portion.

10. The display apparatus of claim 8 , wherein the bottom portion comprises an exposure portion that is exposed when the moving plate moves when the second base plate rotates.

11. The display apparatus of claim 1 , wherein one base plate of the first and second base plates has a substantially cylindrical shape elongated in a third direction crossing the first direction, the other base plate of the first and second base plates comprises a second coupling portion coupled to both ends of the first coupling portion, which are spaced apart from each other in the third direction, and a third portion of the display panel, which is defined between the first and second portions, is wound around the first coupling portion in accordance with a rotation of the second base plate.

12. The display apparatus of claim 1 , wherein the moving plate has a first strength and the pop-up plate has a second strength smaller than the first strength.

13. The display apparatus of claim 1 , wherein, when a case that a rotation angle of the second base plate is 0 and the display panel is flat is referred to as a first state and a case that the rotation angle of the second base plate is 180 and the display panel is folded is referred to as a second state, the moving plate slides toward the rotation axis while the second base plate rotates from the first state to the second state.

14. The display apparatus of claim 13 , wherein the pop-up plate is pressed down and the moving plate slides above the pop-up plate while the second base plate rotates to the second state from the first state.

15. A portable terminal comprising:
a display panel deformed from one state to another state among a first state in which the display panel is flat and a second state in which the display panel is folded;
a first base plate coupled to a first portion of the display panel;
a moving plate directly coupled to a second portion of the display panel, the second portion being spaced apart from the first portion along a first direction;
a pop-up plate configured to support a third portion of the display panel when the display panel is in the first state, the third portion of the display panel being between the first and second portions; and
a second base plate coupled to the first base plate and configured to be rotated relative to the first base plate, the second base plate being sliding-coupled to the moving plate and configured to accommodate the pop-up plate.

16. The portable terminal of claim 15 , wherein the moving plate is configured slide toward the pop-up plate and the pop-up plate is configured to be accommodated in the second base plate by the moving plate when the state of the display panel is changed from the first state to the second state.

17. The portable terminal of claim 16 , wherein the pop-up plate comprises a first inclined surface contacting a second inclined surface of the moving plate when the display panel is in the first state, the first inclined surface having an incline at a first angle with respect to a bottom surface of the pop-up plate, the second inclined surface having an incline at a second angle with respect to an upper surface of the moving plate, and each of the first and second angles being an acute angle.

18. The portable terminal of claim 15 , wherein the pop-up plate is between the moving plate and the second base plate when the display panel is in the second state.

19. The portable terminal of claim 15 , wherein the third portion is bent at a first radius of curvature when the display pane
