Abstract
A display device includes: a housing; a roller rotatably disposed on the housing; a flexible display that is rolled around the roller or unrolled from the roller; a first arm connected to the flexible display; an arm supporter provided in the housing; an arm shaft rotatably supported to the arm supporter; a second arm coupled to the arm shaft and rotated together with the arm shaft to rotate the first arm; a rotation mechanism connected to the second arm to rotate the second arm about the arm shaft; and an angle sensor module connected to at least one of the arm shaft and the second arm.
Claims20
A display device comprising a flexible display, the device comprising:
- housing;
- roller disposed in the housing;
- flexible display configured to be rolled around the roller;
- an upper assembly coupled to an upper portion of the flexible display;
- a lift assembly comprising:
- a motor;
- a first arm coupled to the upper assembly;
- a second arm coupled to the first arm and configured to be pivotably raised in response to operation of the motor;
- a main gear configured to rotate in response to pivoting of the second arm;
- a driven gear engaged with the main gear;
- and
- a first sensor configured to detect an angle of the second arm based on a rotation of the driven gear,
- wherein the detected angle of the second arm based on the rotation of the driven gear is used to determine a vertical position of the upper assembly.
A lift assembly for a flexible display, the lift assembly comprising:
- a motor;
- a first arm coupled to an upper assembly which is coupled to an upper portion of the flexible display;
- a second arm coupled to the first arm and configured to be pivotably raised in response to operation of the motor;
- a main gear configured to rotate in response to pivoting of the second arm;
- a driven gear engaged with the main gear;
- and
- a first sensor configured to detect an angle of the second arm based on a rotation of the driven gear,
- wherein the detected angle of the second arm based on the rotation of the driven gear is used to determine a vertical position of the upper assembly.
