Display device
A display device is disclosed. The display device according to the present invention includes a display panel, a module cover coupled to the rear side of the display panel, and a housing coupled to the rear side of the module cover, wherein the housing comprises a driving unit configured to push at least part of the module cover such that the display panel is in at least one of a first state in which the display panel is flat and a second state in which the display panel is curved, wherein the driving unit comprises a motor assembly, at least one link having one side coupled to the motor assembly and the other side coupled to the module cover, and a guide coming into contact with at least one side of the at least one link to enable the at least one link to be pushed up and pulled down according to direction of a driving force transferred from the motor assembly.
1. A display device, comprising:
a display panel;
a module cover positioned behind the display panel;
a housing positioned behind the module cover, the housing including a rear surface facing the module cover;
a motor assembly positioned between the housing and the module cover and installed on the rear surface of the housing;
a body driven by the motor assembly to move linearly along the rear surface of the housing;
a link including a first side pivotally connected to the body and a second side pivotally connected to the module cover; and
a guide positioned between the link and the housing and installed on the rear surface of the housing.
2. The display device of claim 1 , further including a lead screw driven by the motor assembly, wherein the body is a sum nut that moves along the lead screw.
3. The display device of claim 2 , wherein he link is rotatably coupled with the screw nut and pushed up according to movement of the screw nut.
4. The display device of claim 2 , wherein the link includes a protruding part protruded to the side of the link so as to limit a movement distance of the screw nut.
5. The display device of claim 1 , wherein the guide includes first to fourth guides, wherein at least one of the first to fourth guides supports the link and guides movement of the link.
6. The display device of claim 5 , wherein at least one of the second and third guides is provided with at least one groove supporting the link such that the link slides.
7. The display device of claim 5 , wherein at least one of the second and third guides is coupled with at least one guide rail coupled with the screw nut such that the screw nut moves rectilinearly.
8. The display device of claim 1 , wherein the second state includes a third state in which the left and right sides of the display panel have different curvatures.
9. The display device of claim 1 , further including:
a pinion gear rotated by the Motor assembly; and
a rack gear driven by the pinion gear,
wherein the body is a connector connected to the rack gear.
10. The display device of claim 1 , further comprising:
a first bar rotated by the motor assembly; and
a second bar pivotally connected to the first bar, wherein the body is a connector pivotally connected to the second bar.
11. The display device of claim 1 , wherein the display panel is an organic light-emitting diode (OLED) panel.
12. The display device of claim 1 , wherein the display panel comprises a first state in which the display panel is flat and a second state in which the display panel is curved.
