A plurality of strap ends91bmay be provided, and the plurality of strap ends91bmay be formed at opposite ends of the strap91a. The strap end91bmay protrude from the strap91atoward the fixing segment92. The pin hole91cmay be formed through the strap end91b. The pin hole91cmay be elongated. The skin91dmay cover an outer surface of the core (91a,91b,91c). For example, the core (91a,91b,91c) and the skin91dmay be integrally formed by heterogeneous injection molding. For example, the core (91a,91b,91c) may have a higher tensile strength than the skin91d. The handle91may be coupled to the fixing segment92. The pin P of the fixing segment92may be inserted into the pin hole91cof the handle91.

Referring toFIGS.1to58, there is provided a display device including: a display module including a display panel; an arm having an upper arm that is coupled to a rear of the display module and a lower arm that is hinge-connected to the upper arm; a bottom case to which the lower arm is pivotally connected; and a top case hinge-connected to the bottom case.

The lower arm may include: a lower inner frame that is hinge-connected to the bottom case; and a lower outer cover that covers the lower inner frame and defines an outer appearance of the lower arm. The upper arm may include: an upper inner frame that is hinge-connected to the lower inner frame; and an upper outer cover that covers the upper inner frame and defines an outer appearance of the upper arm. The lower outer cover may include a storage groove formed as an outer surface of the lower outer cover is recessed and in which the upper arm is received when folded.

The bottom case may include: an outer shell that defines an accommodation space and defines an outer appearance of the bottom case; and a frame that is disposed in the accommodation space and coupled to an inside of the outer shell. The arm may further include a bottom mount that is coupled to the frame of the bottom case.

The lower inner frame may include: a lower part that is pivotally connected to the bottom mount; and an upper part that extends from the lower part and is hinge-connected to the upper inner frame. The lower part may include a wiring groove that is recessed inward in an elongated manner. The wiring groove may extend from the bottom mount toward the upper part in a manner of being bent and extending to a lateral side of the lower part while being adjacent to the upper part.

The lower inner frame may include: a lower part that is pivotally connected to the bottom mount; an upper part that extends from the lower part and is hinge-connected to the upper inner frame. The upper part may include: a first connecting portion that is hinge-connected to the upper inner frame; and a second connecting portion that is disposed opposite the first connecting portion with respect to the hinge, the second connecting portion being spaced apart from the hinge. The second connecting portion may include: a holder mount; and a finger that is bent and extends from one side of the holder mount.

A cable holder that is coupled to the second connecting portion may be further provided. The cable holder may include: a mounting block that is coupled to the holder mount; and a holder tip that is bent and extends from one side of the mounting block, the holder tip defining a circle together with the finger.

A cable routed in the arm may be further provided. The cable may extend from the bottom mount, and may be placed in the wiring groove.

A cable routed in the arm may be further provided. The cable may extend long to be placed in the wiring groove, and may be inserted into the circle defined by the holder tip and the finger.

The upper inner frame may include: a rod body that is elongated; an opening that is formed through a portion of the rod body; a first connecting portion that is hinged-connected to the first connecting portion of the lower inner frame; and a second connecting portion that is disposed opposite the first connecting portion, the second connecting portion having at least a portion of a cylinder shape to be inserted into a circle of the lower inner frame. The cable may be inserted into the second connecting portion, and may extend so as to be inserted into the opening of the rod body.

The cable may be electrically connected to the display panel.

The bottom mount may include: a first piece that is hinge-connected to a first side of the lower inner frame and fixed to the bottom case; and a second piece that is hinge-connected to a second side of the lower inner frame and fixed to the frame of the bottom case. The first piece may be spaced apart from the second piece.

A cable routed in the arm may be further provided. The cable may pass between the first piece and the second piece of the bottom mount.

The display module may be configured to be stored in the bottom case or stand upright from the bottom case when the arm performs a pivoting movement.

An arm hinge may be further provided to connect the first connecting portion of the lower inner frame and the first connecting portion of the upper inner frame. The arm hinge may include: a hinge shaft that is connected to the first connecting portion of the lower inner frame; a hinge cam that is configured to rotate on the hinge shaft and fixed to the first connecting portion of the upper inner frame; and an elastic member that is configured to provide an elastic force to the hinge cam with respect to the hinge shaft.

A link may be further provided to connect the arm hinge and the bottom mount.
