Display apparatus
A display apparatus including a display module, and a drive device to deform the display module, is provided. The drive device switches the display module between a planar state and a curved state in which at least one lateral end of the display module protrudes forward. As such, the user may use the display module both in a planar state and a curved state.
1. A display apparatus comprising: a display module; and a drive device to deform the display module, wherein the drive device switches the display module between a planar state and a curved state in which at least one lateral end of the display module protrudes forward,
wherein the drive device pushes said at least one lateral end of the display module forward such that said at least one lateral end of the display module protrude forward, and
wherein the drive device includes at least one motor to generate torque, a plurality of pinions to be rotated by the at least one motor, a pair of racks tooth-engaged with the plurality of pinions so as to be moved in opposite directions via rotation of the plurality of pinions, and a pair of rotating members each having one end rotatably fastened to a corresponding one of the racks and the other end rotatably fastened to one corresponding lateral end of the display module.
2. The display apparatus according to claim 1 , wherein the display module includes a display panel and a support frame to support the display panel, and wherein the display panel and the support frame are formed of deformable materials.
3. The display apparatus according to claim 2 , wherein the display panel includes an organic light emitting diode panel.
4. The display apparatus according to claim 1 , further comprising a guide plate to which the drive device is installed, the guide plate movably supporting the racks.
5. The display apparatus according to claim 4 , wherein the racks include a first rack horizontally movably coupled to one side of the guide plate and a second rack horizontally movably coupled to another side of the guide plate, the first rack and the second rack being moved in opposite directions, wherein the plurality of pinions include a pair of first pinions tooth-engaged with the first rack, and a pair of second pinions tooth-engaged with the second rack, and wherein the at least one motor includes at least two first motors to rotate the respective first pinions, and at least two second motors to rotate the respective second pinions.
