4. The display apparatus of claim 2 , wherein the driving apparatus comprises:
a driving motor configured to generate power;
a pinion rotated by the driving motor; and
a pair of racks engaged with the pinion so as to move in left side and right side directions according to rotation of the pinion, each rack moving in a direction opposite to a direction of the other rack.
5. The display apparatus of claim 1 ,
wherein the plurality of links include a base link receiving power from the driving apparatus, an end link rotatably installed at the display module, and at least one connection link connecting the base link to the end link.
6. The display apparatus of claim 5 , wherein the display module includes a plurality of hinge brackets which are installed at a rear surface of the display module and to which the plurality of links are rotatably coupled.
7. The display apparatus of claim 6 , wherein the end link is rotatably coupled to the hinge bracket, and the base link and the at least one connection link are rotatably coupled to the hinge bracket through a plurality of rotating hinges.
8. The display apparatus of claim 7 , wherein the rotating hinge includes a first hinge part rotatably coupled to the hinge bracket and a second hinge part rotatably coupled to a coupling part between the base link and the connection link.
9. The display apparatus of claim 8 , wherein the rotating hinge includes a pair of guide surfaces that are inclined with respect to the links coupled to the rotating hinge, respectively.
10. The display apparatus of claim 1 , wherein the display module includes a display panel on which a screen is displayed and a support panel supporting a rear surface of the display panel.
11. The display apparatus of claim 10 , wherein the display panel is provided using an organic light emitting diode panel.
12. The display apparatus of claim 1 , further comprising a pair of speaker modules installed at both sides of the display module, respectively.
13. The display apparatus of claim 12 , wherein the pair of speaker modules are rotatably installed at the both sides of the display module.
14. A display apparatus comprising a display unit, wherein the display unit is configured to deformable to be in a flat surface state, a first curved surface state in which both sides of the display unit protrude forward, and a second curved surface state in which the both sides of the display unit retreat backward, wherein the display unit includes:
a display module on which an image is displayed;
a pair of deformation guides configured to guide the display module to be deformed; and
a driving apparatus configured to generate power,
wherein the pair of deformation guides are configured to deform the display module by receiving power from the driving apparatus, and
wherein the pair of deformation guides include a plurality of links that extend in left side and right side directions and that are rotatably coupled to each other.
15. The display apparatus of claim 14 ,
wherein the plurality of links include a base link receiving power from the driving apparatus, an end link rotatably installed at the display module, and at least one connection link connecting the base link to the end link.
16. The display apparatus of claim 15 , wherein:
the display module includes a plurality of hinge brackets which are installed at a rear surface of the display module and to which the plurality of links are rotatably coupled;
the end link is rotatably coupled to the hinge bracket; and
the base link and the at least one connection link are rotatably coupled to the hinge bracket through a plurality of rotating hinges.
17. The display apparatus of claim 14 , further comprising a stand that allows the display unit to be used in an erect state on a horizontal plane,
wherein:
the display unit includes a base member configured to support a central portion of the display module; and
the stand is installed at a lower side of the base member.
18. The display apparatus of claim 14 , further comprising a pair of speaker modules installed at both sides of the display unit, respectively.
19. The display apparatus of claim 18 , wherein the pair of speaker modules are rotatably installed at the both sides of the display unit, respectively.
