Abstract
A display device is disclosed. The display device includes a housing, a flexible display having an upper surface, a lift assembly provided in the housing and coupled to the upper surface of the flexible display screen to extend the flexible display screen outside the housing, a motor provided in the housing and coupled to the lift assembly to raise the flexible display screen, and an elastic member provided adjacent to the upper surface of the flexible display screen, the elastic member configured to apply a vertical force to the upper surface of the flexible display screen.
Claims16
A display device comprising:
- a housing;
- a roller disposed in the housing;
- a flexible display configured to be rolled around the roller;
- an upper assembly coupled to an upper region of the flexible display;
- a lift assembly comprising a plurality of arms coupled to the upper assembly and configured to extend the flexible display from the housing, at least one arm comprising a portion pivotably connecting to a slider through a rod and configured to pivotably joint another arm and support the upper assembly;
- a motor configured to apply force to move the slider in a horizontal direction and lift the lift assembly to extend the flexible display in a vertical direction;
- and a pusher configured to abut the upper assembly when the flexible display is retracted, wherein the pusher is further configured to provide a biasing force to the upper assembly in the vertical direction when the pusher abuts the upper assembly;
- and the pusher no longer abuts the upper assembly after the upper assembly is extended by a predetermined distance by the lift assembly.
A display device comprising:
- a housing;
- a roller disposed in the housing;
- a flexible display configured to be rolled around the roller;
- an upper assembly coupled to an upper region of the flexible display;
- a lift assembly configured to extend the flexible display from the housing, the lift assembly comprising:
- a first arm assembly coupled to a first side of the upper assembly and a second arm assembly coupled to a second side of the upper assembly;
- a motor disposed between the first arm assembly and the second arm assembly and configured to apply force to the lift assembly;
- a first lead screw and a second lead screw configured to be rotated by the motor;
- a first slider engaged with the first lead screw and configured to travel along the first lead screw in response to rotation of the first lead screw;
- a second slider engaged with the second lead screw and configured to travel along the second lead screw in response to rotation of the second lead screw;
- a first rod pivotably coupled to the first slider and configured to apply force to the first arm assembly in response to movement of the first slider;
- and a second rod pivotably coupled to the second slider and configured to apply force to the second arm assembly in response to movement of the second slider;
- and a first pusher configured to provide a biasing force to the first side of the upper assembly in a vertical direction and a second pusher configured to provide a biasing force to the second side of the upper assembly when the first and second pushers abut the upper assembly when the flexible display is retracted;
- and the pusher no longer abuts the upper assembly after the upper assembly is extended by a predetermined distance by the lift assembly.
