A rollable device includes a rollable panel having two surfaces opposed to each other, a heat dissipation sheet disposed on one of the two surfaces of the rollable panel, and a supporting plate disposed between the rollable panel and the heat dissipation sheet. The heat dissipation sheet has a thermal conductivity greater than 200 W/mK.

A frame includes a plurality of profile sections and at least one first adapter assembly. Each profile section includes at least one section extension surface, and one of the at least one section extension surface is provided with at least one first groove therein. Each first adapter assembly includes a first position-limiting block provided with at least one first mounting hole therein. The first position-limiting block is configured to be fixed in a first groove during assembly, and to fix other components to the profile section through the at least one first mounting hole.

An apparatus may include a passive vibration member, a supporting member overlapping the passive vibration member, and a vibration apparatus between the passive vibration member and the supporting member and configured to include first and second active vibration members connected to each other and intersecting with each other. The first active vibration member may be connected to a first member of one of the passive vibration member and the supporting member, and the second active vibration member may be connected to a second member of the other of the passive vibration member and the supporting member.

An apparatus can include a passive vibration member; a vibration device coupled to a rear surface of the passive vibration member; and a supporting member at the rear surface of the passive vibration member. The apparatus can include a first vibration portion; a second vibration portion coupled to a periphery of the first vibration portion; and a connection portion disposed between a periphery of the second vibration portion and the rear surface of the passive vibration member.

A flexible screen display device includes: a hollow housing having an opening; a receiving shaft fixed inside the housing; a first guiding shaft fixed inside the housing; a second guiding shaft fixed inside the housing; a flexible screen, one end of which is connected to the receiving shaft, and the other end of which sticks out of the opening via the first guiding shaft and the second guiding shaft to deploy or receive the flexible screen. The first guiding shaft is close to the receiving shaft with respect to the second guiding shaft, and the flexible screen forms a one-time guided bending section via the first guiding shaft and the second guiding shaft.

A display system can include a stand that includes a base and an arm that extends from the base to an end portion of the arm; and a display housing that includes a display, a rail assembly and an arm socket, translatable via the rail assembly, that receives the end portion of the arm.

A display device including a display panel, and a rear cover panel coupled with the display panel at a rear of the display panel, wherein the rear cover panel includes a front skin forming a front surface facing the display panel, a rear skin forming a rear surface and facing the front skin, a core between the front skin and the rear skin, and a cable hole penetrating the front skin and the rear skin with the core.

The description relates to devices that can include a base assembly, upper assembly, an arm, and a conductor. In one example the base assembly can include a base shaft and the upper assembly can include an upper shaft. The arm can be secured to the base shaft and the upper shaft to translate a range of rotation of the arm around the base shaft to rotation around the display shaft. The conductor can extend from the base assembly into the arm parallel to the base shaft and extend from the arm into the upper assembly parallel to the upper shaft.

Disclosed herein is a display apparatus that uses a display module by selectively setting the display module to a flat surface form and a curved surface form. The display apparatus includes a display module that is bendable and is configured to display an image, and a bending structure configured to deform the display module by moving at least one of a center and both ends of the display module relative to each other to form one of a flat surface form and a curved surface form of the display module.

Disclosed is a display device. The display device of the present disclosure includes a flexible display panel, a source printed circuit board (S-PCB) located adjacent to a lower side of the flexible display panel and electrically coupled to the flexible display panel, a roller comprising a seating portion accommodating the S-PCB, wherein the seating portion is formed by removing a part of an outer circumferential surface of the roller, wherein the flexible display panel is wound around or unwound from the roller, and a cover extending in a longitudinal direction of the roller to cover the S-PCB.
