A flexible display device is provided. A flexible display device according to one embodiment of the present invention comprises a body, a moving plate, a first pulley, a second pulley, a driving track and a flexible display. The flexible display is coupled to outer surfaces of the moving plate and the driving track, and the driving track forms a continuous track shape by itself or together with the moving plate. Therefore, provided is the flexible display device in which a constant tension can be maintained over the entire section of the driving track while the moving plate and the driving track support the flexible display, the occurrence of spring back in the flexible display can be minimized, and damage caused by unevenness of the flexible display, and the like, can be prevented.

Flexible display device

A display device is provided. A display device according to an embodiment of the present invention comprises a body, a moving plate, a bracket, a rack, an actuator and a driving gear. The bracket, rack, actuator and driving gear are coupled to one another to form a driving module, and the bracket comprises a moving guide, an upper cover and a heat dissipation fin. According to an embodiment of the present invention, the display device can be manufactured in which the moving plate can move reciprocatively in a stable manner with respect to the body, the heat dissipation of the actuator can be effectively performed, and the thickness and size of the driving module can be minimized.

Display device

A flexible display device is disclosed. The flexible display device includes a first body, a second body, a flexible display, a first wheel, and a second wheel. The first wheel and the second wheel may be rotatably coupled to the first body. A lateral surface of the first wheel comes into contact with a first rolling surface of the second body in a first contact direction, and a lateral surface of the second wheel comes into contact with a second rolling surface of the second body in a second contact direction, wherein the first contact direction and the second contact direction are symmetrical to each other about a reference surface. When the second body moves relative to the first body in a first direction or in a direction opposite to the first direction, the first wheel and the second wheel roll on the first rolling surface and the second rolling surface.

A flexible display device is provided. The flexible display device according to an embodiment of the present disclosure may include a first body, a second body, a first link, and a second link. According to an embodiment of the present disclosure, in an unfolding state, the first link and the second link may not protrude out of the first body and the second body, and the first link and the second link may be changed in a form that may protect the flexible display during folding.

A flexible display device is provided. A flexible display device according to an embodiment of the present invention is configured to include a body, a moving plate, a flexible display, and a driving module. The driving module is configured to include a bracket, a sliding plate including a rack, a driving motor, and a driving gear. The driving module is coupled to a body and a moving plate after assembling the driving module so that it is possible to prevent a sliding plate which slidably moves together with a flexible display after assembling the flexible display device from being loosen and also prevent the idle operation of the driving gear.
