Provided is a display device including a housing; a roller installed inside the housing; a display unit wound around the roller; a link having a first arm povitably mounted on the display unit and a second arm pivotably connected to the first arm and povitably on to the housing; a lead screw installed inside the housing; a slider moving on the lead screw according to rotation of the lead screw; a rod having one side connected to the slider and the other side connected to the second arm; a plurality of springs allowing the lead screw to be inserted thereinto, providing an elastic force to the slider, and arranged in series; a spacer located between the plurality of springs and allowing the lead screw to be inserted thereinto; and a damping member supporting a lower side of the spring.

Display device

A display device is disclosed. The display device of the present disclosure comprises: a housing extended to be long; a roller provided inside the housing; and a display panel which is wound around or unwound from the roller, wherein the housing includes first and second base frames assembled together with a lower frame, the lower frame is assembled together with or fixed to the first base frame and/or the second base frame by at least one fixed pin so as to prevent sagging caused by a weight increase.

Display device having sagging prevention structure

This display device comprises: a housing; a roller; a display panel; a module cover that has a plurality of segments sequentially arranged in the vertical direction of the display panel from the rear side of the display panel, and winds or unwinds from the roller together with the display panel; a foldable link that is located on the rear side of the display panel, and has one side pivotably connected to the housing and the other side pivotably connected to the upper side of the module cover so as to keep the display panel and the module cover erect while unwinding the same from the roller; a speaker assembly that is installed inside the housing and has a curved surface corresponding to the curvature of the roller and spaced apart from the outer circumferential surface of the roller; and a buffering member that is fixed to the curved surface of the speaker assembly between the curved surface of the speaker assembly and the outer circumferential surface of the roller.

A rollable display device includes: a soft display panel; a main roller for winding or unwinding the soft display panel; an actuator coupled to the soft display panel to ascend and descend the soft display panel; a housing having the main roller mounted therein, wherein an opening extending in a first direction is defined in a top of the housing to retract and extend the soft display panel therethrough; and an elastic portion having one end coupled to a perimeter of the opening and protruding to cover at least a portion of the opening, wherein the elastic portion includes a rubber portion having a predetermined length along the first direction. The rollable display device may minimize exposure of an interior of the housing to prevent foreign substances from entering.

Rollable display device

The present embodiment comprises: a stand having a side plate provided with a cable receiving groove portion for receiving a cable; a cable bracket fastened to the stand and having a separation portion being spaced apart from the side surface of the cable receiving groove portion; and a cover body having a side cover that covers the side surface of the cable receiving groove portion and the cable bracket, and a rear cover that is bent from the side cover, wherein a through hole, through which the cable passes, is formed between the rear cover and the side plate, and a part of the cable is accommodated between the side surface and the separation portion of the cable receiving groove portion.
