Abstract

A display apparatus is provided. The display apparatus includes a housing having an opening, a first roll and a second roll rotatably provided within the housing, a display configured to be wound on the first roll, and to be retracted and withdrawn through the opening according to a rotation direction of the first roll, a protection member configured to be wound on the first roll together with the display or to be wound in the second roll as the display is withdrawn from the housing, and a moveable component mounting part which is disposed between the first roll and the second roll and on which various components are mounted within the housing. The component mounting part moves within the housing to selectively provide space and utilize space according to a retraction operation and a withdrawal operation of the display.

Claims

1. A display apparatus, comprising:

a housing having an opening;

a first roll and a second roll rotatably provided within the housing;

a display configured to be;

wound on the first roll, and

retracted into the housing and withdrawn from the housing, through the opening, according to a rotation direction of the first roll;

a protection member configured to be;

wound on the first roll together with the display, and

wound on the second roll; and

a component mounting part moveably disposed between the first roll and the second roll,

wherein the component mounting part is configured to move within the housing according to a retraction operation and a withdrawal operation of the display.

2. The display apparatus of claim 1,

wherein the component mounting part is further configured to move to be spaced from the first roll in response to the display and the protection member being wound on the first roll, and

wherein the component mounting part is further configured to move to be spaced from the second roll in response to the display being withdrawn from the housing and the protection member being wound on the second roll.

3. The display apparatus of claim 1, further comprising a guide hole configured to guide a movement of the component mounting part, wherein the guide hole is formed in an inner lateral surface of the housing.

4. The display apparatus of claim 1, wherein the component mounting part is further configured to move on a plane parallel to a plane in which the display is withdrawn.

5. The display apparatus of claim 1, wherein the housing further comprises:

a first driving source configured to move the component mounting part;

a second driving source configured to rotate the first roll; and

a third driving source configured to rotate the second roll.

6. The display apparatus of claim 5, further comprising a controller provided in the inside of the housing and configured to:

receive information through a switch provided in the housing; and

control the first, second and third driving sources.

7. The display apparatus of claim 1, wherein, in response to the display and the protection member being wound in the first roll, the protection member and the display are alternately wound on the first roll in such a manner that one surface of the protection member faces one surface of the display, and the other surface of the protection member faces the other surface of the display.

8. The display apparatus of claim 1, wherein the protection member has the same shape as the display.

9. The display apparatus as claimed in claim 1,

wherein the first roll is coupled to one end of the display, and

wherein a grip is provided at the other end of the display.

10. The display apparatus of claim 1,

wherein the first roll is coupled to one end of the protection member, and

wherein the second roll is coupled to the other end of the protection member.

11. The display apparatus of claim 1, wherein the protection member is in contact with a top surface of the display.

12. A display apparatus, comprising:

a housing having an opening;

a first roll and a second roll rotatably provided within the housing;

a display configured to be;

wound on the first roll, and

retracted into the housing and withdrawn from the housing through the opening, according to a rotation direction of the first roll;

a protection member configured to be;

wound on the first roll together with the display, and

wound on the second roll; and

a component mounting part moveably disposed between the first roll and the second roll,

wherein the component mounting part is configured to alternately move to a space which is provided by unrolling the display and the protection member from the first roll or to a space which is provided by unrolling the protection member from the second roll.

13. The display apparatus of claim 12,

wherein, in response to the display being withdrawn from the housing, a space in a periphery of the first roll is provided and the component mounting part is further configured to move toward the first roll, and

wherein, in response to the display being retracted into the housing, a space in a periphery of the second roll is provided and the component mounting part is further configured to move toward the second roll.

14. The display apparatus of claim 12, further comprising a guide hole configured to guide a movement of the component mounting part, wherein the guide hole is formed in an inner lateral surface of the housing.

15. The display apparatus of claim 12, wherein the housing further comprises:

a first driving source configured to move the component mounting part;

a second driving source configured to rotate the first roll; and

a third driving source configured to rotate the second roll,

wherein the first, second and third driving sources are configured to perform operations preset by a controller provided within the housing.

16. A method to minimize a housing of a retractable display, the method comprising:

providing a component mounting part moveably disposed within a housing between a first roll and a second roll;

moving, when space becomes available in the housing around the first roll due to withdrawal of a display rolled on the first roll, the component mounting part toward the first roll; and

moving, when space becomes available in the housing around the second roll due to removal of a protection member rolled on the second roll, the component mounting part toward the second roll.

17. The method of claim 16, further comprising:

rolling the display and the protection member on the first roll for storage within the housing, such that space becomes available in the housing around the second roll,

wherein the protection member is disposed between layers of the display on the first roll.

18. The method of claim 16, further comprising:

unrolling the display and the protection member from the first roll such that space becomes available in the housing around the first roll;

withdrawing the display from the housing; and

rolling the protection member on the second roll for storage within the housing.
