[0040] The display device according to an exemplary embodiment of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0041] <Display device - Sliding display device>.

[0042] A sliding display device refers to a display device that can display images even when it is sliding. Sliding display devices offer greater flexibility than conventional display devices in the related art. The shape of a sliding display device can be freely changed depending on whether it is used. Specifically, when not in use, the sliding display device can be slid and stored with a reduced exposed panel area. Conversely, when in use, it can be unfolded and used again.

[0043] Figure 1A and Figure 1B This is a perspective view of a display device according to an embodiment of the present disclosure.

[0044] First, refer to Figure 1A and Figure 1B According to an embodiment of the present disclosure, the display device 100 includes a display unit DP and a housing unit HP.

[0045] The display unit DP is configured to display an image to a user. For example, display elements and circuitry, wiring, and components for operating the display elements can be provided on the display unit DP. In this case, since the display device 100 according to the embodiment of this disclosure is a slidable display device, the display unit DP can be configured to be slidable. For example, the display unit DP may include a display panel, a back cover, and a plurality of back bars that are flexible enough to be slidable. Reference will be made below. Figure 2 and Figure 3 A more detailed description of the display unit (DP).

[0046] The housing HP is a casing that can accommodate the display unit DP. The display unit DP can be slidably installed within the housing HP. Alternatively, the display unit DP can be slidably installed outside the housing HP.

[0047] The housing part HP may include an upper frame F1, a lower frame, a front frame F2, a rear frame, and a side frame F3. The side frame F3 of the housing part HP may also include a guide rail that slides in conjunction with the movement of the lifting part. Therefore, when the display part DP moves up or down, it can prevent the display part DP from wobbling. The outward display area of ​​the display part DP can be varied by combining the sliding movement of the lifting part and the sliding movement of the side frame F3 of the housing part HP.

[0048] That is, the display unit DP may include: a first display area AA1, which is exposed to the outside through the housing part HP when the movable unit of the lifting part described below is positioned at the lowest side; and a second display area AA2, which has an area exposed to the outside and varies according to the upward / downward movement of the movable unit.

[0049] Figure 1AThe diagram shows the display unit DP of the display device 100 in a state where it is maximally retracted. The maximally retracted state refers to a state where only the first display area AA1 of the display unit DP of the display device 100 is exposed to the outside. That is, when the user does not need to see a large image, a configuration where the entire area of ​​the display unit DP is not exposed to the outside of the housing HP is aesthetically advantageous. Therefore, the maximally retracted state can be defined as a state where the display unit DP is slid and maximizedly contained within the housing HP. Furthermore, in the maximally retracted state of the display unit DP, only the minimum required display area of ​​the display device 100 may be exposed, and the display device 100 can be easily transported.

[0050] Figure 1B The diagram shows the state in which the display section DP of the display device 100 is maximized. Maximum expansion means that the smallest area of ​​the display section DP of the display device 100 is contained within the housing section HP, while both the first display area AA1 and the second display area AA2 are exposed to the outside. That is, the maximum expansion state can be defined as the state in which the display section DP is slid and positioned to the maximum extent outside the housing section HP and cannot be slid further so that the user can see the image on the display device 100.

[0051] Display Department

[0052] Figure 2 This is a top plan view of the display section of a display device according to an embodiment of the present disclosure. Figure 3 This is a rear view of the display section of a display device according to an embodiment of the present disclosure. (Refer to...) Figure 2 and Figure 3 The display unit DP of the display device 100 includes multiple back bars 110, a back cover 111, a display panel 120, a flexible film 130, and a printed circuit board 140.

[0053] Display panel 120 is a panel configured to display images to a user. Display panel 120 may include display elements configured to display images, driving elements configured to operate the display elements, and lines configured to transmit various types of signals to the display elements and the driving elements.

[0054] Different display elements can be defined depending on the type of display panel 120. For example, if the display panel 120 is an organic light-emitting display panel, the display element can be an organic light-emitting element that includes an anode, an organic light-emitting layer, and a cathode. For example, if the display panel 120 is a liquid crystal display panel, the display element can be a liquid crystal display element. Furthermore, if the display panel 120 is a light-emitting display panel that includes LEDs, the display element can be an LED. Here, it is assumed that the display panel 120 is an organic light-emitting display panel. However, the display panel 120 is not limited to an organic light-emitting display panel. Furthermore, since the display device 100 according to the embodiments of this disclosure is a slidable display device, the display panel 120 can be implemented as a flexible display panel for sliding.

[0055] Reference Figure 2 The display panel 120 includes a display area AA and a non-display area NA.

[0056] The display area AA is an area of ​​the display panel 120 in which an image is displayed. The display area AA may include a plurality of sub-pixels constituting a plurality of pixels, and driving circuitry configured to operate the plurality of sub-pixels. The plurality of sub-pixels are the smallest units constituting the display area AA. Display elements may be disposed in each of the plurality of sub-pixels. For example, each of the plurality of sub-pixels may include a light-emitting element comprising an anode, a light-emitting portion, and a cathode. However, the present disclosure is not limited thereto. Furthermore, the circuitry configured to operate the plurality of sub-pixels may include driving elements, lines, etc. For example, the circuitry may include, but is not limited to, thin-film transistors, storage capacitors, gate lines, data lines, etc. Furthermore, as described above, the display portion AA may include: a first display area AA1, which is exposed to the outside through the housing portion HP when the movable unit of the lifting portion is positioned at the lowermost side; and a second display area AA2, which has an area exposed to the outside and varies according to the movement of the movable unit in the upward / downward direction.

[0057] The non-display area NA is an area where no image is displayed. The non-display area NA surrounds the outer perimeter of the display area AA. Various lines and circuits for operating the organic light-emitting elements in the display area AA are disposed in the non-display area NA. For example, the non-display area NA may include, but is not limited to, link lines for transmitting signals to multiple sub-pixels and circuits in the display area AA. The non-display area NA may include driver ICs, such as gate driver ICs and data driver ICs.

[0058] The flexible film 130 is a film having various types of components disposed on a flexible base film. The flexible film 130 may be stretchable. A portion of the flexible film 130, along with the stretchable area MA, may be wound around or unwound from a roller. The flexible film 130 can provide signals to multiple sub-pixels and circuits in the display area AA. The flexible film 130 can be electrically connected to the display panel 120. The flexible film 130 is disposed at one end of the non-display area NA of the display panel 120 and provides power voltage, data voltage, etc., to multiple sub-pixels and circuits in the display area AA. Figure 2 The number of flexible membranes 130 shown is an example, and the number of flexible membranes 130 can be varied according to the design. However, this disclosure is not limited thereto.

[0059] Simultaneously, driver ICs, such as gate driver ICs and data driver ICs, can also be disposed on the flexible film 130. The driver IC is a component configured to process data for displaying an image and to process drive signals for processing that data. The driver IC can be disposed in various ways, such as chip-on-glass (COG), chip-on-film (COF), and tape-on-package (TCP), depending on its mounting method. However, for the sake of clarity, a configuration in which the driver IC is mounted on the flexible film 130 using the chip-on-film method has been described. However, this disclosure is not limited thereto.

[0060] A printed circuit board 140 is disposed at one end of the flexible film 130 and connected to the flexible film 130. The printed circuit board 140 is a component used to supply signals to the driver IC. The printed circuit board 140 provides various signals to the driver IC, such as drive signals and data signals. Various types of components can be disposed on the printed circuit board 140. For example, a timing controller, a power supply unit, etc., can be disposed on the printed circuit board 140. Figure 2 A printed circuit board 140 is shown. However, the number of printed circuit boards 140 can be varied depending on the design. This disclosure is not limited thereto.

[0061] At the same time, despite Figure 2 Although not shown, additional printed circuit boards (PCBs) connected to PCB 140 can also be provided. For example, PCB 140 can be referred to as a source PCB (S-PCB), on which a data drive unit is mounted. The additional PCB connected to PCB 140 can be referred to as a control PCB (C-PCB), on which a timing controller, etc., is mounted. The additional PCBs can be provided in the roller section. The additional PCBs can also be provided outside the roller section and within the housing section HP.

[0062] Reference Figure 2 and Figure 3The back cover 111 can be disposed on the rear surface of the display panel 120 and supports the display panel 120, one or more flexible films 130, and the printed circuit board 140. The size of the back cover 111 can be larger than the size of the display panel 120. The back cover 111 can protect other components of the display unit DP from the outside.

[0063] The back cover 111 can be made of a rigid material. At least a portion of the back cover 111 can be flexible to slide with the display panel 120. For example, the back cover 111 can be made of a metallic material (e.g., stainless steel, stainless iron (SUS)), Invar, or a plastic material. However, the material of the back cover 111 can be varied according to the design, provided that it meets physical performance requirements such as heat distortion, radius of curvature, and rigidity. However, this disclosure is not limited thereto. Furthermore, the back cover 111 can include a plurality of openings. The width of each of the plurality of openings in the direction perpendicular to the sliding direction can be greater than the width of each of the plurality of openings in the sliding direction.

[0064] Reference Figure 3 Multiple back supports 110 can be disposed on the rear surface of the display panel 120 and the rear surface of the back cover 111. The multiple back supports 110 can support the display panel 120 and the back cover 111. When the display panel 120 slides, the supporting force of the back supports 110 can support the display panel 120, thereby preventing the display panel 120 from being scratched or damaged. Each of the multiple back supports 110 can be referred to as an apron. The multiple back supports 110 can be made of plastic material. However, this disclosure is not limited thereto. Furthermore, the multiple back supports 110 can be attached by separate bonding layers or foam tape.

[0065] Figure 2 and Figure 3 A back cover 111 and a plurality of back bars 110 are shown disposed on the rear surface of the display panel 120. However, only the plurality of back bars 110 may be disposed on the rear surface of the display panel 120. Alternatively, only the back cover 111 may be disposed on the rear surface of the display panel 120.

[0066] <Coupling structure of the lifting section>.

[0067] Figure 4A and Figure 4B This is a front perspective view of a display device according to an embodiment of the present disclosure. Figure 5A and Figure 5B This is a front perspective view of the lifting section of a display device according to an embodiment of the present disclosure. Figure 6A and Figure 6B This is a rear perspective view of the lifting section of a display device according to an embodiment of the present disclosure. For ease of description, Figure 4A and Figure 4BDisplay panel 120 is omitted. Figure 4A , Figure 5A and Figure 6A This is a view showing the movable unit 170 of the lifting section 150 positioned at its lowest point. Figure 4B , Figure 5B and Figure 6B This is a view showing the movable unit 170 of the lifting section 150 positioned at the topmost position.

[0068] Reference Figures 4A to 6B The display device 100 according to the embodiments of the present disclosure also includes a lifting part 150, a guide drum GD, and fixing blocks B1 and B2.

[0069] The lifting unit 150 is a device that moves and slides one end of the display panel 120 in an upward / downward direction. The lifting unit 150 may include a fixing unit 160, a movable unit 170, a panel connecting block 180, and a motor 190.

[0070] The fixing unit 160 is used to fix the display panel 120 and the lifting part 150 to the display device 100. That is, the fixing unit 160 can be fixed to the lower frame F4 of the housing part HP of the display device 100. A first fixing block B1 with a strip shape is fastened to the center portion of the fixing unit 160, so that the other end of the display panel 120 can be fixed. In addition, the other end of the fixing unit 160 can be fixed to the lower frame F4 of the housing part HP, and one end of the fixing unit 160 can be fastened to the movable unit 170 of the lifting part 150. Therefore, even when the lifting part 150 moves up or down, the fixing unit 160 can be fixed and not move, and serves to support other components of the lifting part 150, so that the components of the lifting part 150 can move smoothly. Referring to the following... Figure 7 and Figure 8 The components of the fixed unit 160 are described in detail.

[0071] The movable unit 170 of the lifting section 150 is used to move one end of the display panel 120 while the fixed unit 160 moves linearly in the upward / downward direction. One end of the movable unit 170 can be connected to the fixed unit 160, and the other end of the movable unit 170 can be connected to the panel connecting block 180. Furthermore, a motor 190 is connected to the movable unit 170, so that the movable unit 170 can move linearly in conjunction with the rotation of the motor 190, and the end of the display panel 120 can move in the upward / downward direction. Reference will be made below. Figure 7 , Figure 9A and Figure 9B The components of the movable unit 170 are described in detail.

[0072] The panel connecting block 180 of the lifting section 150 is used to fix the display panel 120 to the lifting section 150. That is, one end of the panel connecting block 180 can be connected to the movable unit 170 of the lifting section 150, and the other end of the panel connecting block 180 can be connected to the back cover 111 provided at the end of the display panel 120 by means of the second fixing block B2. Therefore, when the movable unit 170 moves linearly, the panel connecting block 180 also moves in the vertical direction, so that the end of the display panel 120 can move. (Refer to the following...) Figure 7 , Figure 10A and Figure 10B The components of panel connecting block 180 are described in detail.

[0073] A guide drum GD is disposed at one end of the movable unit 170 of the lifting section 150. The guide drum GD can be disposed in a direction perpendicular to the linear movement direction of the movable unit 170 and supports the display panel 120. Because the display panel 120 of the sliding display device (e.g., the display device 100 according to this disclosure) is flexible, a device is needed to support the display panel 120 so that the display panel 120 remains flat and does not wrinkle during sliding operation. The guide drum GD is disposed on the upper side of the movable unit 170 of the lifting section 150 and extends horizontally in a direction perpendicular to the upward / downward movement of the lifting section 150. The guide drum GD may include a fixed roller. In this case, the fixed roller may have a cylindrical shape. The cross-sectional shape of the fixed roller may be circular.

[0074] When the lifting section 150 moves up or down, the guide drum GD can also move up or down together with the lifting section 150. In this case, the guide drum GD can be used as a support, allowing the display panel 120 to move along the surface of the guide drum GD. That is, the display panel 120 can slide tautly along the periphery of the guide drum GD.

[0075] Fixing blocks B1 and B2 may include a first fixing block B1 and a second fixing block B2. The first fixing block B1 may be disposed in the central region of the fixing unit 160 of the lifting part 150. The second fixing block B2 may be disposed on the top of the panel connecting block 180 of the lifting part 150.

[0076] Fixing blocks B1 and B2 are configured to fix two opposite ends of the display panel 120. Therefore, the first fixing block B1 may have a strip shape that connects to the fixing unit 160 of the lifting portion 150 to fix the other end of the display panel 120 to the fixing unit 160. The second fixing block B2 may have a strip shape that connects to the panel connecting block 180 of the lifting portion 150 to fix one end of the display panel 120 to the panel connecting block 180. Specifically, the first fixing block B1 is used to fix the other end of the display panel 120 to the fixing unit 160 of the lifting portion 150 when the printed circuit board 140 or the back cover 111 of the display panel 120 is fixed by the first fixing block B1. The second fixing block B2 is used to fix one end of the display panel 120 to the panel connecting block 180 of the lifting portion 150 when the back cover 111 is fixed by the second fixing block B2.

[0077] In the display device 100 according to an embodiment of the present disclosure, the lifting portion 150 can move linearly in an upward / downward direction, thereby allowing the display panel 120 to slide. Referring below... Figures 7 to 9B Describe the specific configuration of the lifting unit 150.

[0078] <Configuration of the upgrade department>.

[0079] Figure 7 This is an exploded perspective view of the lifting section of a display device according to an embodiment of the present disclosure. Figure 8 This is an enlarged view of the fixing unit of the lifting section of a display device according to an embodiment of the present disclosure. Figure 9A and Figure 9B This is an exploded perspective view showing a movable unit of the lifting section of a display device according to an embodiment of the present disclosure. Figure 10A and Figure 10B This is an enlarged view showing the panel connecting block of the lifting section of a display device according to an embodiment of the present disclosure.

[0080] First, as described above, the lifting unit 150 may include a fixed unit 160, a movable unit 170, a panel connecting block 180, and a motor 190.

[0081] Reference Figure 7 and Figure 8 The fixing unit 160 of the lifting part 150 may include a first base part 161, a first track part 162 and a first belt fastening part 163.

[0082] The first base portion 161 of the fixing unit 160 is a support for the lower frame F4 fixed to the housing portion HP. The first base portion 161 can support the first track portion 162 on its rear surface and maintain a stable state by limiting the swaying and torsion of the fixing unit 160. The first base portion 161 is formed to have a length corresponding to half of the maximum height of the lifting portion 150. The first track portion 162 of the fixing unit 160 and the first belt fastening portion 163 are connected and fixed to the first base portion 161.

[0083] The first track portion 162 is fixed to a surface of the first base portion 161 and is mounted vertically. The movable unit 170 of the lifting portion 150 can move while sliding along the first track portion 162. Specifically, the first track portion 162 may be a guide rail, and the first track portion 162 may be connected to and fixed to a surface of the first base portion 161. The first track portion 162 may be formed to have a length corresponding to the first base portion 161. The first track portion 162 may include two guide rails arranged parallel to each other and facing each other. The first track portion 162 defines the movement path of the movable unit 170, and the movable unit 170 includes a second track portion 172 that can be operated in conjunction with the first track portion 162. That is, the movable unit 170 can move linearly in the vertical direction along the trajectory of the first track portion 162.

[0084] A first belt fastening portion 163 may be disposed on one side of the first base portion 161 of the fixed unit 160 and fastened to the belt 175 included in the movable unit 170. Although not shown in the figures, the first belt fastening portion 163 may have a fastening groove, such that the first belt fastening portion 163 can be fastened to the belt 175. However, the method of fastening the first belt fastening portion 163 and the belt 175 is not limited to this. Various fastening methods can be used.

[0085] Therefore, since the first belt fastening portion 163 is fastened to the belt 175 of the movable unit 170 while the first belt fastening portion 163 is fixed to the fixed unit 160, the first belt fastening portion 163 can be synchronized with the movement of the belt 175 achieved by the rotational force of the motor 190. That is, when the belt 175 rotates due to the rotation of the motor 190, the first belt fastening portion 163 also moves. However, since the first base portion 161 connected to the first belt fastening portion 163 is fixed to the lower frame F4, the movable unit 170 including the belt 175 moves upward or downward by a relative force.

[0086] Next, the motor 190 can be fixed to the movable unit 170. The motor 190 can be connected to a power generator, such as a separate external power source or an embedded battery, and be powered. The motor 190 can generate rotational force using electrical energy and provide driving force to the movable unit 170 by transmitting the rotational force to the connecting shaft 173. Furthermore, since the motor 190 is fixed to the movable unit 170, the motor 190 can move up or down as the movable unit 170 moves up or down.

[0087] Reference Figure 7 , Figure 9A and Figure 9B In the components of the lifting section 150, the movable unit 170 may include a second base section 171, a second track section 172, a connecting shaft 173, pulleys 174a and 174b, a belt 175, anti-separation members 177a and 177b, spacer members 178a and 178b, a motor fixing unit 179, and a third track section 176.

[0088] The second base portion 171 of the movable unit 170 serves as a support for the movable unit 170, to which the motor 190 is fixed. The second base portion 171 can be disposed between the second track portion 172 and the third track portion 176, and supports the third track portion 176 on its rear surface. The second base portion 171 can maintain a stable state by limiting the swaying and torsion of the movable unit 170. The second base portion 171 is formed to have a length corresponding to half the maximum height of the lifting portion 150. The second track portion 172, the third track portion 176, and the connecting shaft 173 of the movable unit 170 are connected to and fixed to the second base portion 171.

[0089] The second track portion 172 of the movable unit 170 is fixed to the rear surface of the second base portion 171 (i.e., the lower surface of the second base portion 171 adjacent to the fixed unit 160) and disposed on the rear surface of the second base portion 171, such that the second track portion 172 operates in conjunction with the first track portion 162 of the fixed unit 160. Because the second track portion 172 needs to be track-coupled to the first track portion 162 of the fixed unit 160, the movable unit 170 includes a track structure that guides the movable unit 170 when it slides relative to the fixed unit 160 in the vertical direction. That is, the second track portion 172 may include a plurality of grooves coupled to the first track portion 162. The first track portion 162 includes, for example... Figure 7In the case of two parallel tracks facing each other, the second track portion 172 may have two grooves, allowing the two tracks of the first track portion 162 to be coupled to the second track portion 172. However, the second track portion 172 may be shorter than the second base portion 171, since the second track portion 172 only needs to be engaged with the first track portion 162 to operate.

[0090] The connecting shaft 173 of the movable unit 170 can be fixed to the second base portion 171 and connected to the motor 190 and the first pulley 174a. The connecting shaft 173, pulleys 174a and 174b, and belt 175 of the movable unit 170 can be connected to the motor 190 and convert the rotational motion from the motor 190 into linear motion. The connecting shaft 173 receives the rotational force from the motor 190 and rotates about the rotational axis. The pulleys 174a and 174b, fastened to the connecting shaft 173, also receive the rotational force from the motor 190 and rotate about the connecting shaft 173. Therefore, the belt 175 can rotate together with the pulleys 174a and 174b while corresponding to the rotational motion of the connecting shaft 173.

[0091] The connecting shaft 173 is fixed to penetrate the second base portion 171 and is rotatably fastened to the second base portion 171. Therefore, the movement of the connecting shaft 173 can be restricted except for its rotational movement about the rotation axis.

[0092] Furthermore, the movable unit 170 may also include a motor fixing unit 179, allowing the motor 190 and the connecting shaft 173 to rotate easily. The motor fixing unit 179 is disposed between the second base portion 171, the connecting shaft 173, and the motor 190, and fixes the motor 190 so that the motor 190 does not separate from the movable unit 170 of the lifting portion 150.

[0093] The movable unit 170 includes a belt 175 and pulleys 174a and 174b configured to rotate and move the belt 175. The pulleys 174a and 174b are rotatably fixed to a second base portion 171. The pulleys 174a and 174b are configured as a pair of left and right pulleys. The pulleys 174a and 174b are located at both ends of the second base portion 171 and connected to the belt 175. In this case, the pair of pulleys 174a and 174b may include a first pulley 174a and a second pulley 174b. The first pulley 174a is connected to a connecting shaft 173, and the second pulley 174b rotates in conjunction with the first pulley 174a. For example, teeth may be formed on the outer surfaces of the pulleys 174a and 174b, and grooves may be formed in the inner surface of the belt 175 and mesh with the teeth of the pulleys 174a and 174b. However, this disclosure is not limited thereto.

[0094] As described above, pulleys 174a and 174b can receive rotational force from the motor 190 from the connecting shaft 173, and belt 175 can rotate by receiving driving force from pulleys 174a and 174b. Therefore, belt 175 is wound around the first pulley 174a and the second pulley 174b. Thus, when the motor 190 rotates in one direction, power can be transmitted to belt 175 via pulleys 174a and 174b, and power can also be transmitted to the first belt fastening portion 163 and the second belt fastening portion 183 coupled to belt 175. Therefore, the first belt fastening portion 163 and the second belt fastening portion 183 move, and the movable unit 170 and the panel connecting block 180 move.

[0095] Furthermore, the movable unit 170 may also include anti-separation members 177a and 177b and spacer members 178a and 178b, allowing the pulleys 174a and 174b and the belt 175 to rotate easily. The anti-separation members 177a and 177b may be disposed on the side of the belt 175. The first anti-separation member 177a and the second anti-separation member 177b may be fastened to the first pulley 174a and the second pulley 174b, respectively. The anti-separation members 177a and 177b are disposed on the side of the belt 175 and the pulleys 174a and 174b, allowing the belt 175 to rotate stably without separation. Additionally, the spacer members 178a and 178b are disposed between the pulleys 174a and 174b and the second base portion 171, and are used to allow the belt 175 to be spaced apart from the second base portion 171, so that the second base portion 171 does not obstruct the movement of the belt 175 when it rotates. Spacer members 178a and 178b may include a first spacer member 178a configured to be adjacent to a first pulley 174a, and a second spacer member 178b configured to be adjacent to a second pulley 174b.

[0096] The third track portion 176 of the movable unit 170 is fixed to a surface of the second base portion 171 and is mounted vertically. The panel connecting block 180 of the lifting portion 150 can slide along the third track portion 176. Specifically, the third track portion 176 can be a guide rail, and the third track portion 176 can be connected to and fixed to a surface of the second base portion 171. The third track portion 176 can be formed to have a length corresponding to that of the second base portion 171. The third track portion 176 can include two tracks arranged parallel to each other and facing each other. The third track portion 176 defines the movement path of the panel connecting block 180, which includes a fourth track portion 182 that can be operated in conjunction with the third track portion 176. That is, the panel connecting block 180 can move linearly in the vertical direction along the track of the third track portion 176.

[0097] Finally, refer to Figure 7 , Figure 10Aand Figure 10B In the components of the lifting section 150, the panel connecting block 180 may include a third base portion 181, a fourth track portion 182, and a second belt fastening portion 183.

[0098] The third base portion 181 of the panel connecting block 180 serves as a support for the panel connecting block 180, to which the end of the display panel 120 is connected. The third base portion 181 supports the fourth track portion 182 and maintains stability by limiting the swaying and torsion of the panel connecting block 180. The third base portion 181 is formed to have a length corresponding to the fourth track portion 182. The fourth track portion 182 and the second fastening portion 183 of the panel connecting block 180 are connected to and fixed to the third base portion 181. Furthermore, a second fixing block B2, to which a strip-shaped back cover 111 is fixed, can be fixed to the panel connecting block 180. Therefore, when the panel connecting block 180 moves vertically in the upward / downward direction, the second fixing block B2 connected to the panel connecting block 180 and the display panel 120 can move upward or downward.

[0099] The fourth track portion 182 of the panel connecting block 180 is fixed to and disposed on the rear surface of the third base portion 181 (i.e., the lower surface of the third base portion 181 adjacent to the movable unit 170), such that the fourth track portion 182 operates in conjunction with the third track portion 176 of the movable unit 170. Because the fourth track portion 182 needs to be track-coupled with the third track portion 176 of the movable unit 170, the panel connecting block 180 includes a track structure that guides the panel connecting block 180 when it slides relative to the movable unit 170. That is, the fourth track portion 182 may include multiple grooves, and the protrusions of the third track portion 176 are coupled to the multiple grooves. The third track portion 176 is configured as follows... Figure 7 In the case of the parallel arrangement of the two tracks facing each other, the fourth track portion 182 can be configured as two recesses such that the two tracks of the third track portion 176 are coupled to the fourth track portion 182. However, since the fourth track portion 182 is configured to operate in conjunction with the third track portion 17, the fourth track portion 182 does not need to be installed with a length corresponding to the first base portion 161 and the second base portion 171, but can be shorter than the first base portion 161 and the second base portion 171, such as... Figure 7 As shown.

[0100] The second belt fastening portion 183 may be disposed on one side of the third base portion 181 of the panel connecting block 180 and fastened to the belt 175 included in the movable unit 170. The second belt fastening portion 183 may have a fastening groove so that the panel connecting block 180 can be fastened to the belt 175. However, the method of fastening the second belt fastening portion 183 and the belt 175 is not limited to this.

[0101] Therefore, since the second belt fastening portion 183 is fastened to the belt 175 of the movable unit 170 while the second belt fastening portion 183 is fixed to the panel connecting block 180, the second belt fastening portion 183 can be synchronized with the movement of the belt 175 achieved by the rotational force of the motor 190. That is, when the belt 175 moves by the rotation of the motor 190, the third belt fastening portion 183 also moves, causing the panel connecting block 180 to move upward or downward.

[0102] <Sliding operation of the lifting section>

[0103] Figure 11A and Figure 11B This is a front perspective view of a display device according to an embodiment of the present disclosure. Figure 12A and Figure 12B This is a rear perspective view of a display device according to an embodiment of the present disclosure. For ease of description, Figures 11A to 12B Only the display panel 120, back cover 111, flexible film 130, printed circuit board 140, guide drum GD, and lifting section 150 of the various components of the display device 100 are shown. Figure 11A and Figure 12A This is a view showing the movable unit 170 of the lifting section 150 positioned at its lowest position. Figure 11B and Figure 12B This is a view showing the movable unit 170 of the lifting section 150 positioned at the topmost position.

[0104] Reference Figure 11A and Figure 12A When the end of the display panel 120 is positioned at its lowest point, the movable unit 170 of the lifting portion 150 overlaps with the fixed unit 160, and the panel connecting block 180 is disposed at the end of the fixed unit 160. That is, when the end of the display panel 120 is positioned at its lowest point, the movable unit 170 of the lifting portion 150 and the panel connecting block 180 can each have their lowest possible height.

[0105] Reference Figure 11B and Figure 12BWhen the end of the display panel 120 is positioned at its uppermost position, the movable unit 170 is moved upward to its maximum extent so as not to overlap with the fixed unit 160, and the panel connecting block 180 is disposed at the end of the movable unit 170. That is, when the end of the display panel 120 is positioned at its uppermost position, the movable unit 170 of the lifting part 150 and the panel connecting block 180 can each have their maximum height.

[0106] Reference Figures 11A to 12B When the lifting unit 150 moves up or down by the operation of the motor 190, the display panel 120 slides.

[0107] First, when the motor 190 rotates, the belt 175 rotates via the connecting shaft 173, the first pulley 174a, and the second pulley 174b, causing the second track portion 172 of the movable unit 170 to move linearly along the first track portion 162 of the fixed unit 160. That is, when the motor 190 rotates, the connecting shaft 173 also rotates. When the connecting shaft 173 rotates, the first pulley 174a and the second pulley 174b rotate. When the first pulley 174a and the second pulley 174b rotate, the belt 175 rotates. In this case, since the first belt fastening portion 163 of the fixed unit 160 is fixed to a specific position on the belt 175, the second track portion 172 of the movable unit 170 moves linearly along the first track portion 162 of the fixed unit 160 due to the rotation of the belt 175. Therefore, finally, the movable unit 170 moves upward or downward based on the fixed unit 160.

[0108] Simultaneously, when the motor 190 rotates, the fourth track portion 182 of the panel connecting block 180 moves linearly along the third track portion 176 of the movable unit 170. Specifically, when the motor 190 rotates, the connecting shaft 173 also rotates. When the connecting shaft 173 rotates, the first pulley 174a and the second pulley 174b rotate. When the first pulley 174a and the second pulley 174b rotate, the belt 175 rotates. In this case, since the second belt fastening portion 183 of the panel connecting block 180 is fixed at a specific position on the belt 175, the fourth track portion 182 of the panel connecting block 180 moves linearly along the third track portion 176 of the movable unit 170 due to the rotation of the belt 175. Therefore, finally, the panel connecting block 180 moves up or down based on the movable unit 170.

[0109] Therefore, the movable unit 170 and the panel connecting block 180 move simultaneously relative to the fixed unit 160, and the end of the display panel 120 connected to the panel connecting block 180 via the second fixed block B2 and the guide drum GD provided on the upper side of the lifting part 150 moves upward or downward. Thus, the area of ​​the display area AA of the display panel 120 exposed to the outside is changed.

[0110] Below, we will refer to Figure 13 A more detailed description of the operation of the lifting section 150.

[0111] Figure 13 This is a cross-sectional view showing the linear motion of the lifting section of a display device according to an embodiment of the present disclosure. For ease of description, Figure 13 Only the fixed unit 160, movable unit 170 and panel connecting block 180 of the various components of the lifting section 150 are shown.

[0112] First, refer to Figures 11A to 13 The process of moving the movable unit 170 and the panel connecting block 180 upwards is described. For example... Figure 13 As shown on the left, when the end of the display panel 120 is positioned at its lowest position, the movable unit 170 and the panel connecting block 180 are also positioned at their lowest positions. When the motor 190 rotates to move the movable unit 170 and the panel connecting block 180 upwards, the connecting shaft 173 rotates. When the connecting shaft 173 rotates, the first pulley 174a and the second pulley 174b rotate. When the first pulley 174a and the second pulley 174b rotate, the belt 175 rotates. In this case, since the first belt fastening portion 163 of the fixing unit 160 is fixed at a specific position on the belt 175, the second track portion 172 of the movable unit 170 moves upwards along the first track portion 162 of the fixing unit 160 due to the rotation of the belt 175.

[0113] Furthermore, when the movable unit 170 moves upward along the first track portion 162 of the fixed unit 160, the panel connecting block 180 also moves upward simultaneously due to the rotation of the motor 190. Specifically, when the motor 190 rotates, the connecting shaft 173 also rotates. When the connecting shaft 173 rotates, the first pulley 174a and the second pulley 174b rotate. When the first pulley 174a and the second pulley 174b rotate, the belt 175 rotates. In this case, since the second belt fastening portion 183 of the panel connecting block 180 is fixed at a specific position on the belt 175, the fourth track portion 182 of the panel connecting block 180 moves upward along the third track portion 176 of the movable unit 170 due to the rotation of the belt 175.

[0114] Therefore, the movable unit 170 and the panel connecting block 180 move upwards due to the rotation of the motor 190. (See reference...) Figure 13Assuming the maximum lifting height of the movable unit 170 relative to the fixed unit 160 is A, the maximum lifting height of the panel connecting block 180 relative to the movable unit 170 can also be A. Therefore, when the movable unit 170 moves upward by A / 2 relative to the fixed unit 160 due to the rotation of the motor 190, the panel connecting block 180 also moves upward by A / 2 relative to the movable unit 170, causing the panel connecting block 180 to move upward by A relative to the fixed unit 160. Figure 13 As shown in the middle. When the movable unit 170 moves upward by position A relative to the fixed unit 160 due to the additional rotation of the motor 190, the panel connecting block 180 also moves upward by position A relative to the movable unit 170, causing the panel connecting block 180 to move upward by 2A relative to the fixed unit 160, as shown. Figure 13 As shown on the right.

[0115] Next, we will refer to Figures 11A to 13 The process of moving the movable unit 170 and the panel connecting block 180 downwards is described. For example... Figure 13 As shown on the right, when the end of the display panel 120 is positioned at its uppermost position, both the movable unit 170 and the panel connecting block 180 are positioned at their uppermost positions. When the motor 190 rotates in the opposite direction to the direction of rotation during the upward movement of the movable unit 170 and the panel connecting block 180, the connecting shaft 173 rotates to move the movable unit 170 and the panel connecting block 180 downwards. When the connecting shaft 173 rotates, the first pulley 174a and the second pulley 174b rotate. When the first pulley 174a and the second pulley 174b rotate, the belt 175 rotates. In this case, since the first belt fastening portion 163 of the fixing unit 160 is fixed at a specific position on the belt 175, the second track portion 172 of the movable unit 170 moves downwards along the first track portion 162 of the fixing unit 160 due to the rotation of the belt 175.

[0116] Furthermore, when the movable unit 170 moves downward along the first track portion 162 of the fixed unit 160, the panel connecting block 180 also moves downward simultaneously due to the rotation of the motor 190. Specifically, when the motor 190 rotates in the opposite direction to the direction of rotation during the upward movement of the movable unit 170 and the panel connecting block 180, the connecting shaft 173 rotates. When the connecting shaft 173 rotates, the first pulley 174a and the second pulley 174b rotate. When the first pulley 174a and the second pulley 174b rotate, the belt 175 rotates. In this case, since the second belt fastening portion 183 of the panel connecting block 180 is fixed at a specific position on the belt 175, the fourth track portion 182 of the panel connecting block 180 moves downward along the third track portion 176 of the movable unit 170 due to the rotation of the belt 175.

[0117] Therefore, the movable unit 170 and the panel connecting block 180 move downwards due to the rotation of the motor 190. (Refer to...) Figure 13 Assuming the maximum lifting height of the movable unit 170 relative to the fixed unit 160 is A, the maximum lifting height of the panel connecting block 180 relative to the movable unit 170 can also be A. Therefore, when the movable unit 170 moves downward by A / 2 relative to the fixed unit 160 due to the rotation of the motor 190, the panel connecting block 180 also moves downward by A / 2 relative to the movable unit 170, causing the panel connecting block 180 to move downward by A relative to the fixed unit 160. Figure 13 As shown in the middle. When the movable unit 170 moves downward by A relative to the fixed unit 160 due to the additional rotation of the motor 190, the panel connecting block 180 also moves downward by A relative to the movable unit 170, causing the panel connecting block 180 to move downward by 2A relative to the fixed unit 160. Figure 13 As shown on the left.

[0118] Sliding display devices may include a motor configured to operate a lifting section, which is configured to move the display panel in an up / down direction. However, in the case of a typical sliding display device, the lifting section needs to move the display panel a certain distance. Therefore, since the lifting section needs to move the same amount as the display panel expands its display area, it is difficult to ensure efficient space utilization of the display device, and the overall size of the display device also increases.

[0119] Therefore, in the display device 100 according to the embodiments of this disclosure, the lifting unit 150 includes a fixing unit 160, a movable unit 170, a panel connecting block 180, and a motor 190, and the fixing unit 160 and the panel connecting block 180 are fastened to the belt 175 of the movable unit 170. Therefore, a wider area of ​​the display panel 120 can be exposed to the outside of the display device 100. Furthermore, when the belt 175 rotates due to the rotation of the motor 190, not only does the movable unit 170 move relative to the fixing unit 160, but the panel connecting block 180 connected to the end of the display panel 120 also moves from the lowermost end of the movable unit 170 to the uppermost end of the movable unit 170. Therefore, when the movable unit 170 of the lifting unit 150 moves from the lowermost position to the uppermost position, the distance the end of the display panel 120 moves can be twice the moving distance of the movable unit 170.

[0120] Therefore, according to the display device 100 of the embodiment of the present disclosure, a wider variable area of ​​the display area AA of the display panel 120 can be ensured. Even though the display device 100 of the embodiment of the present disclosure, in which the end of the display panel 120 is attached to the panel connecting block 180 with band 175 fastened to the movable unit 170, includes a lifting portion 150 having the same height as display devices in the related art, when the movable unit 170 moves from the lowermost position to the uppermost position, the end of the display panel 120 moves upward by a distance twice the moving distance of the movable unit 170. Therefore, a wider variable area of ​​the display area AA of the display panel 120 exposed to the outside can be ensured.

[0121] Exemplary embodiments of this disclosure can also be described as follows:

[0122] According to one aspect of this disclosure, a display device is provided.

[0127] When the motor rotates, the belt can rotate through the connecting shaft, the first pulley and the second pulley, causing the fourth track section to move linearly along the third track section.

[0128] The display device may also include a guide drum disposed at one end of the movable unit, positioned in a direction perpendicular to the linear movement direction of the movable unit, and configured to support the display panel.

[0129] The display device may further include: a first fixing block having a strip shape and connected to a fixing unit to fix the other end of the display panel to the fixing unit; and a second fixing block having a strip shape and connected to a panel connecting block to fix one end of the display panel to the panel connecting block.
