Pursuant to 35 U.S.C. § 119(a), this application claims the benefit of earlier filing date and right of priority to Korean Patent Application No. 10-2020-0131273, filed on Oct. 12, 2020, the contents of which are all hereby incorporated by reference herein in their entirety.
The present disclosure relates to a display device.
With the development of information society, demand for various kinds of display devices is increasing. In response to this demand, various kinds of display devices, such as LCDs (Liquid Crystal Display Devices), PDPs (Plasma Display Panels), ELDs (Electro-luminescent Displays), VFDs (Vacuum Fluorescent Displays) and OLEDs (Organic Light-Emitting Diodes) have been recently researched and used.
Among these, an LCD panel includes a TFT substrate and a color substrate, which face each other with a liquid crystal layer interposed therebetween, in order to display an image using light supplied from a backlight unit. Meanwhile, an OLED panel is configured to display an image by depositing a self-luminescent organic layer on a substrate having a transparent electrode formed thereon.
In recent years, structural features of a display device including a stand have been intensively conducted.
Therefore, the present disclosure has been made in view of the above problems, and it is an object of the present disclosure to provide a display device having a rotating structure for a display device.

What is claimed is:1. A display device comprising:a head comprising a display panel; a stand supporting the head; and a moving assembly coupled to the head and to the stand, wherein the moving assembly comprises a rotational assembly for rotating the head with respect to the stand and a tilt assembly for allowing the head to be inclined with respect to the stand, wherein the rotational assembly comprises: a base; and a rotating plate rotatably disposed at the base about a first rotational axis, wherein the tilt assembly comprises: a holder fixed to the stand; a rotating body coupled to the base and rotatably coupled to the holder about a second rotational axis, wherein the first rotational axis intersects the second rotational axis; a rod providing the second rotational axis and passing through portions of the holder and the rotating body overlapping each other in a direction of the second rotational axis; and a spring wound around an outer circumferential surface of the rod between the holder and the rotating body, wherein a first end of the spring is coupled to the holder, and wherein the rotating body comprises a protrusion protruding toward a point adjacent to a second end of the spring opposite to the first end from another portion of the rotating body next to the portion of the rotating body overlapping the holder, and supported by the spring. 2. The display device according to claim 1 , wherein the rotating plate is coupled to the head at a rear side of the head,wherein the holder is positioned behind the base, and wherein the rotating body is positioned between the base and the holder. 3. The display device according to claim 1 , wherein the rod extends in a lateral direction,wherein the holder comprises: a body coupled to the stand; a first wing angled in a forward direction from the body; and a second wing bent in the forward direction from the body, wherein the second wing is spaced apart from the first wing with respect to the lateral direction, and wherein the rod extends through the first wing and the second wing. 4. The display device according to claim 3 , wherein the rotating body comprises:a plate coupled to the base; and a connector coupled to the plate at a rear side of the plate, wherein the connector is rotatably coupled to the first wing and the second wing. 5. The display device according to claim 4 , wherein the connector comprises:a first part coupled to the plate; a second part bent in a backward direction from the first part to contact the first wing; a third part bent in the backward direction from the first part to contact the second wing; and a fourth part bent in the backward direction from the first part and to be positioned between the second part and the third part, wherein the fourth part defines the protrusion, and wherein the rod extends through the second part and the third part. 6. The display device according to claim 5 , wherein the second end of the spring corresponds to an unobstructed end; andwherein the fourth part comprises a recess depressed in a forward direction from a rear side of the fourth part and is supported by the spring at a position adjacent to the unobstructed end. 7. The display device according to claim 6 , wherein the spring comprises a plurality of springs each spaced apart from each other in the lateral direction, andwherein at least one of the plurality of springs is supported by the fourth part at a right end or left end of the recess. 8. The display device according to claim 5 , further comprising a sleeve around the outer circumferential surface of the rod,wherein the spring is wound around an outer circumferential surface of the sleeve. 9. The display device according to claim 5 , further comprising a bracket coupled to the body and the stand,wherein the second part and the third part are spaced apart in the forward direction from the bracket by a determined distance. 10. The display device according to claim 5 , wherein an outer surface of the first wing is in contact with an inner surface of the second part,wherein the connector further comprises an engagement recess depressed in an upward direction from a lower side of the second part, wherein the holder further comprises a stopper projecting outwards from the outer surface of the first wing, and wherein the engagement recess is spaced apart from the stopper and surrounds a portion of the stopper. 11. The display device according to claim 10 , wherein the stopper is positioned on a rotational path of the engagement recess and limits a rotation of the engagement recess and the connector. 12. The display device according to claim 1 , wherein the rotational assembly further comprises:a guide slot formed in the rotating plate for defining an arc relative to the first rotational axis of the rotating plate; and a slot pin formed on the base and is disposed in the guide slot. 13. The display device according to claim 12 , wherein the rotating plate is configured to have a disc shape and comprises a drive gear formed along an outer circumferential surface of the rotating plate,wherein the guide slot comprises a first guide slot positioned opposite to the drive gear with respect to a rotational center of the rotating plate and is formed through the rotating plate; and the slot pin comprises a first slot pin projecting from the base and disposed in the first guide slot. 14.
