Abstract
An image display device includes a flexible display unit transformable by a force between a first state and a second state having different curved degrees; a pressing member disposed at a rear surface of the flexible display unit, to apply the force to the flexible display unit; a driving unit to push or pull the pressing member such that a curved state of the pressing member is implemented; and an adjusting unit to couple the pressing member and the driving unit to each other, and movable with respect to the driving unit, the adjusting unit to adjust the curved state of the pressing member.
Claims27
An image display device, comprising:
- a flexible display unit transformable by a force between a first state and a second state having different curved degrees;
- a pressing member disposed at a rear surface of the flexible display unit, to apply the force to the flexible display unit;
- a driving unit to push or pull the pressing member such that a curved state of the pressing member is implemented;
- and
- an adjusting unit to couple the pressing member and the driving unit to each other, and movable with respect to the driving unit, the adjusting unit to adjust the curved state of the pressing member,
- wherein the driving unit includes:
- a driving motor to generate a rotational force at a driving shaft;
- a bevel gear to change a direction of the rotational force generated at the driving shaft;
- and
- a lead screw coupled to the bevel gear to be rotated by operation of the driving motor, and screw-coupled to the adjusting unit to move the adjusting unit close to or far from the driving unit according to a rotational direction of the lead screw.
An image display device, comprising:
- a flexible display unit transformable by a force between a first state and a second state having different curved degrees;
- a pressing member disposed at a rear surface of the flexible display unit, to apply the force to the flexible display unit;
- a driving unit to push or pull the pressing member such that a curved state of the pressing member is implemented;
- an adjusting unit to couple the pressing member and the driving unit to each other, and movable with respect to the driving unit, the adjusting unit to adjust the curved state of the pressing member;
- and
- an operation restricting unit to restrict an operation of the driving unit when the adjusting unit has moved more than a preset range by the operation of the driving unit,
- wherein the operation restricting unit includes:
- a limit switch disposed at the rear surface of the flexible display unit;
- and
- a clicker disposed at the adjusting unit, to press against the limit switch if the adjusting unit has moved more than a preset range such that the operation restricting unit generates a signal.
