[0041] In the following, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Moreover, for ease of description, the scale, size, and thickness of each element illustrated in the drawings may differ from the actual scale, size, and thickness. Therefore, the illustrated elements are not limited to the specific scale, size, and thickness illustrated in the drawings.

[0042] Figure 1A This is a perspective view schematically illustrating a display device with the display panel in an embedded state according to an embodiment of the present disclosure. Figure 1B , Figure 1C and Figure 1D This is a perspective view schematically illustrating a display device with the display panel in various withdrawn states according to embodiments of the present disclosure.

[0043] like Figure 1AAs shown, the display device 100 includes a display panel 120 embedded in a cover module 110. The cover module 110 can be attached to furniture, appliances, facilities, etc., such as headboards, tables, or partitions. However, this disclosure is not limited thereto.

[0044] like Figure 1B As shown, the display panel 120, which is pulled down and embedded inside the cover module 110, can be pulled up and fully extended outside the cover module 110.

[0045] Here, the display panel 120 according to the embodiments of this disclosure can be formed of a transparent display panel, allowing the user to see objects or images located on the opposite side through the display panel 120. Additionally, the user can view images from one side and the other side of the display panel 120.

[0046] When the display panel 120 is formed of a transparent display panel, such as Figure 1C As shown, the light shield 130 can be further pulled out from the cover module 110 to the rear surface of the display panel 120.

[0047] By preventing objects or images located on opposite sides of the display panel 120 from being transmitted through the light shield 130, the focus of the image displayed on the display panel 120 can be improved. Therefore, the user can perceive the image displayed on the display panel 120 more clearly.

[0048] In other words, transparent display panels can function as transparent electronic devices to achieve information recognition, information processing, and information display, thereby solving the spatial and visual constraints of existing electronic devices.

[0049] For example, transparent display panels can be implemented as smart windows for use in buildings or automobiles to display backgrounds or images. As the inventors of this disclosure recognize, transparent display panels do not have limitations in contrast in dark environments, but have the disadvantage of reduced contrast in normal, well-lit environments.

[0050] Therefore, the light shield 130 can be further pulled out from the cover module 110 to the rear surface of the display panel 120, thereby enabling a light shielding mode for blocking light and a transmission mode for transmitting light to prevent a reduction in the contrast of the transparent display panel.

[0051] In addition, such as Figure 1D As shown, in the display device 100 according to the embodiments of the present disclosure, only a portion of the display panel 120 can be extracted from the cover module 110, and most of the display panel 120 can be embedded inside the cover module 110, thereby also realizing an always-on display (AOD) device.

[0052] Even when no image is displayed on the display panel 120, the AOD device can display AOD data that the user can check at any time. AOD data may include, but is not limited to, information about the date, time, weather, event alarms, etc., and the AOD data can be changed according to the user's settings.

Figure 3A This is a perspective view illustrating the arrangement of the sleeve and guide rod according to an embodiment of the present disclosure. Figure 3B This is a perspective view illustrating the arrangement of guide rails according to an embodiment of the present disclosure.

[0054] Figure 4A This is a perspective view illustrating a first drive system according to an embodiment of the present disclosure. Figure 4B This is a perspective view illustrating a first motor assembly according to an embodiment of the present disclosure. Figure 4C This is a perspective view illustrating the state in which the first drive system and the display panel are connected to each other according to an embodiment of the present disclosure.

[0055] Figure 5A This is a perspective view illustrating a display device in which the display panel is pulled down according to an embodiment of the present disclosure. Figure 5B This is a perspective view illustrating a display device in which the display panel is pulled up according to an embodiment of the present disclosure, and Figure 5C This is another perspective view illustrating a display device in which the display panel is pulled up according to an embodiment of the present disclosure. Figure 6 This is a perspective view illustrating a tensioner mounted on a first drive line according to an embodiment of the present disclosure.

[0056] As shown in the figure, the display device 100 according to the embodiments of the present disclosure may include a cover module 110, a display panel 120, a light shield 130, a first drive system 150 and a second drive system 160, a pair of guide rails 170a and 170b, and a first elevation assistance system 180 and a second elevation assistance system 190.

[0057] The cover module 110 may be box-shaped to accommodate the display panel 120, the first driving system 150, and the second driving system 160, and may include a front cover 111 and a rear cover 113. The front cover 111 may be disposed on the front surface of the display panel 120, the light shield 130 may be disposed on the rear surface of the display panel 120, and the rear cover 113 may be disposed on the rear surface of the light shield 130.

[0058] Here, the display panel 120 can be one of various display devices such as a liquid crystal display (LCD) device, a plasma display panel (PDP) device, a field emission display (FED) device, an electroluminescent display (ELD) device, and an organic light-emitting diode (OLED) display device. The display panel 120 can preferably use an OLED, which is a representative of flexible display devices that can maintain display performance even when bent like paper.

[0059] OLEDs are self-emissive devices, and because they do not require backlighting as used in liquid crystal displays, which are non-emissive devices, OLEDs can be very light and thin.

[0060] Compared to LCD displays, OLEDs offer wider viewing angles, higher contrast, and lower power consumption. Furthermore, OLEDs are driven by low-voltage direct current (DC) and have a fast response time. In addition, OLEDs are highly resistant to external shocks and, because their components are solid-state, can be used over a wide temperature range.

[0061] In particular, due to its simple manufacturing process, OLED has the advantage of significantly reducing production costs compared to liquid crystal displays.

[0062] The display panel 120 made of OLED may include a first substrate and a second substrate facing the first substrate, and the first substrate and the second substrate may be spaced apart from each other and bonded to each other by an adhesive protective layer.

[0063] Although not shown, a driving thin-film transistor can be formed for each pixel region on the first substrate, and each pixel region can be provided with a first electrode connected to each driving thin-film transistor, an organic light-emitting layer on the first electrode that emits light of a specific color, and a second electrode on the organic light-emitting layer. However, the implementation is not limited to this.

[0064] Organic light-emitting layers can display red, green, and blue light. Typically, individual organic materials emitting red, green, or blue light can be patterned and used for each pixel.

[0065] The first electrode, the second electrode, and the organic light-emitting layer formed therebetween can constitute a light-emitting diode. In a display panel having this structure, the first electrode can be used as the anode, and the second electrode can be used as the cathode. However, this disclosure is not limited thereto. Alternatively, the first electrode can be used as the cathode, and the second electrode can be used as the anode.

[0066] The display panel 120 according to embodiments of the present disclosure may include a transmissive region and a light-emitting region. The transmissive region is the area that transmits the background seen through the rear surface of the display panel 120. That is, the background outside the display panel 120 can be transmitted through the transmissive region of the display panel 120 like transparent glass and can be provided to the user.

[0067] In addition, light-emitting diodes can be placed in the light-emitting area to display image information implemented by the display panel 120.

[0068] The first bottom cover 121 may be disposed at the lower end of the display panel 120 relative to a first direction, which is the direction in which the display panel 120 is pulled out of the cover module 110 and pulled upward. In this embodiment, the first direction is the +Y axis direction defined in the figure. However, the first direction can also be various applicable directions, such as the horizontal direction.

[0069] When the display panel 120 is removed from or inserted into the cover module 110, the first bottom cover 121 can be raised and lowered together with the display panel 120. When the display panel 120 is removed from the cover module 110, the first bottom cover 121 can be disposed inside the cover module 110 to support the display panel 120.

[0070] The first bottom cover 121 can be connected to the first drive system 150.

[0071] like Figure 3A As shown, a pair of first sleeves 123a and second sleeves 123b can be disposed at both ends of the first bottom cover 121. The first sleeves 123a and second sleeves 123b can be respectively inserted into the first guide rods 117a and 117b fixed to the cover module 110, and can be raised and lowered together with the display panel 120 along the longitudinal direction (e.g., the Y direction) of the first guide rods 117a and 117b (i.e., the vertical direction in the context of the drawings).

[0072] The first sleeve 123a and the second sleeve 123b, as well as the first guide rod 117a and the second guide rod 117b, can be respectively disposed on both sides of the cover module 110. When lowered to the inside of the cover module 110 and raised to the outside of the cover module 110, the display panel 120 can be stably raised and lowered without being biased to either side.

[0073] In this configuration, the first guide rod 117a and the second guide rod 117b may further include stops for limiting the lifting height of the first sleeve 123a and the second sleeve 123b. However, the implementation is not limited to this.

[0074] Although not shown in the figure, a second bottom cover may also be provided at the lower end of the light shield 130 disposed on the rear surface of the display panel 120. The second bottom cover can be raised and lowered together with the light shield 130 and is disposed inside the cover module 110. However, the implementation is not limited to this.

[0075] The second bottom cover can be connected to the second drive system 160.

[0076] Additionally, a pair of third and fourth sleeves can be provided at both ends of the second bottom cover. The third and fourth sleeves can be raised and lowered together with the light shield 130 along the longitudinal direction (e.g., the vertical direction in the context of the drawings) of the third guide rod 118a and the fourth guide rod 118b fixed to the cover module 110.

[0077] A pair of guide rails 170a and 170b can be positioned relative to a second direction (e.g., the +Y axis direction defined in the figure) perpendicular to the first direction in which the display panel 120 and the light shield 130 are pulled out. Figure 5A The X-direction shown is positioned at both ends of the display panel 120 and the light shield 130. For example... Figure 3B As shown, each of a pair of guide rails 170a and 170b may be provided with a first mounting groove 171 and a second mounting groove 173, and the end of the display panel 120 and the end of the light shield 130 are respectively mounted and inserted into the first mounting groove 171 and the second mounting groove 173.

[0078] Therefore, when the display panel 120 and the light shield 130 are raised and lowered from the cover module 110, a pair of guide rails 170a and 170b can respectively support and guide the two ends of each of the display panel 120 and the light shield 130.

[0079] In this configuration, the front cover 111 may be equipped with a first drive system 150 connected to the display panel 120. A light shield 130 disposed on the rear surface of the display panel 120 may be connected to a second drive system 160 disposed in the rear cover 113.

[0080] Reference Figure 4A Referring in detail to the first drive system 150, the first drive system 150 may include a first motor assembly 152 and a first wire assembly 154, and the first motor assembly 152 may include a first motor 151 and a first wiredrum 153.

[0081] Here, the first motor 151 can transmit rotational force to the first drum 153, and may include an electric motor and a reducer. The electric motor can provide rotational force by using electricity, and various types of motors, such as servo motors and stepper motors, can be selected.

[0082] By precisely controlling the rotation of the first wire drum 153, the first motor 151 can precisely control the extraction length of the first wire assembly 154 wound around the first wire drum 153.

[0083] like Figure 4B As shown, the first wire drum 153 may include a first winding portion 153a and a second winding portion 153b connected to a rotatable shaft of the first motor 151. One end of the first drive wire 157 of the first wire assembly 154 may be connected to and wound around the first winding portion 153a, and the other end of the first drive wire 157 of the first wire assembly 154 may be connected to and wound around the second winding portion 153b.

[0084] The first line assembly 154 may include a first pulley 155a, a second pulley 155b, a third pulley 155c, a fourth pulley 155d, and a fifth pulley 155e, as well as a first drive line 157. When the front cover 111 is divided into an upper and a lower end, the first motor assembly 152 may be positioned at a first corner (right corner) corresponding to the upper end of the front cover 111. The first pulley 155a may be positioned at a second corner (left corner) corresponding to the upper end of the front cover 111, and may be coaxially positioned with the first motor assembly 152 in a second direction perpendicular to the first direction (the +X / -X axis direction defined in the figure). Alternatively, the first motor assembly 152 may also be positioned at a second corner (left corner) corresponding to the upper end of the front cover 111. The first pulley 155a may be positioned at a first corner (right corner) corresponding to the upper end of the front cover 111, and may be coaxially positioned with the first motor assembly 152 in a second direction perpendicular to the first direction (the +X / -X axis direction defined in the figure).

[0085] The second pulley 155b can be positioned at the second corner (left corner) corresponding to the lower end of the front cover 111, and can be coaxially positioned with the first pulley 155a in the first direction (the +Y / -Y axis direction defined in the figure). The third pulley 155c can be positioned at the first corner (right corner) corresponding to the lower end of the front cover 111, and can be coaxially positioned with the second pulley 155b in the second direction perpendicular to the first direction (the +X / -X axis direction defined in the figure).

[0086] The fourth pulley 155d can be positioned corresponding to the first corner (right corner) of the upper end of the front cover 111. The fourth pulley 155d can be disposed on the outside of the first motor assembly 152 and coaxially positioned with the first motor assembly 152 in the second direction (the +X / -X axis direction defined in the figure). The fifth pulley 155e can be positioned corresponding to the first corner (right corner) of the lower end of the front cover 111. The fifth pulley 155e can be disposed on the outside of the third pulley 155c and coaxially positioned with the third pulley 155c in the second direction (the +X / -X axis direction defined in the figure).

[0087] The fourth pulley 155d and the fifth pulley 155e can be positioned coaxially with each other in the first direction (the +Y / -Y axis direction defined in the figure).

[0088] In the first wire assembly 154, the first drive wire 157 can extend from the first winding portion 153a of the first wire drum 153 of the first motor assembly 152 and cross the first pulley 155a, the second pulley 155b, the third pulley 155c, the fourth pulley 155d and the fifth pulley 155e, such that the other end of the first drive wire 157 can be wound around the second winding portion 153b of the first wire drum 153.

[0089] That is, the first drive line 157, wound around the first winding portion 153a of the first wire drum 153, can descend while crossing the first pulley 155a and can also cross the second pulley 155b. Then, the first drive line 157 can cross the third pulley 155c while simultaneously crossing the second pulley 155b, and the first drive line 157 can rise to cross the fourth pulley 155d. Next, the first drive line 157 can descend while crossing the fourth pulley 155d and can also cross the fifth pulley 155e. Afterwards, the first drive line 157 can be wound around the second winding portion 153b of the first wire drum 153. However, the implementation is not limited to this.

[0090] Therefore, the first drive line 157 of the first line assembly 154 according to the embodiments of the present disclosure can rotate in one direction while forming a closed curve by the rotational force of the first motor assembly 152.

[0091] At this time, when the first drive line 157 is divided into a first region A exposed between the first pulley 155a and the second pulley 155b and a second region B exposed between the fourth pulley 155d and the fifth pulley 155e, a pair of first line fixing plates 159a and second line fixing plates 159b can be fixed to the first region A and the second region B of the first drive line 157 respectively, as follows. Figure 4C As shown in the image.

[0092] Here, when the first drive line 157 rotates and forms a closed curve through the rotational force of the first motor assembly 152, since the first region A and the second region B of the first drive line 157 rotate in the same or substantially the same direction, a pair of first line fixing plates 159a and second line fixing plates 159b fixed to the first region A and the second region B can be raised and lowered in the same or substantially the same direction according to the rotation of the first drive line 157.

[0093] Here, a pair of first line fixing plates 159a and second line fixing plates 159b can be assembled and fastened to the first sleeve 123a and the second sleeve 123b, respectively. The pair of first line fixing plates 159a and second line fixing plates 159b can transmit power for lifting the display panel 120 to the first bottom cover 121.

[0094] That is, the first sleeve 123a and the second sleeve 123b, which are assembled and fastened to the first line fixing plate 159a and the second line fixing plate 159b, can be installed on the first bottom cover 121 located at the lower end of the display panel 120, and the first region A and the second region B of the first drive line 157 can be raised and lowered, so that the display panel 120, together with the first bottom cover 121 on which the first sleeve 123a and the second sleeve 123b are installed, can be raised and lowered longitudinally along the first region A and the second region B of the first drive line 157. However, the implementation is not limited to this.

[0095] Therefore, the display panel 120 can be pulled down and embedded inside the cover module 110, or it can be pulled up and pulled out of the cover module 110.

[0096] That is, such as Figure 5A As shown, the display panel 120 can be embedded inside the cover module 110 and pulled down, and one end of the first drive line 157 can be wound around the first winding portion 153a of the first wire drum 153. When the first wire drum 153 of the first motor assembly 152 of the first drive system 150 rotates clockwise by the rotational force of the first motor 151, the third region C of the first drive line 157 exposed between the first pulley 155a and the second pulley 155b can move from the first pulley 155a to the first motor assembly 152.

[0097] Additionally, the first region A of the first drive line 157 can be moved from the second pulley 155b to the first pulley 155a, and the fourth region D can be moved from the third pulley 155c to the second pulley 155b.

[0098] Meanwhile, the other end of the first drive line 157, which is wound around the second winding portion 153b of the first wire drum 153, can be unwound around the second winding portion 153b, so that the fifth region E of the first drive line 157 can be moved from the first motor assembly 152 to the fifth pulley 155e, and the second region B of the first drive line 157 can be moved from the fifth pulley 155e to the fourth pulley 155d.

[0099] Furthermore, since the sixth region F of the first drive line 157 can move from the fourth pulley 155d to the third pulley 155c, the first drive line 157 can rotate while forming a closed curve between the first wire drum 153 of the first motor assembly 152 and the first pulleys 155a, 155b, 155c, 155d, and 155e of the first drive line 157.

[0100] At this time, both the first region A and the second region B of the first drive line 157 can move upward along the first direction (the +Y axis direction defined in the figure), and the first line fixing plate 159a and the second line fixing plate 159b fixed to the first region A and the second region B of the first drive line 157 can also move upward. Accordingly, as Figure 5B As shown, the first bottom cover 121, to which the first line fixing plate 159a and the second line fixing plate 159b are assembled and fastened, can move upward, thereby allowing the display panel 120 equipped with the first bottom cover 121 to be raised. However, the embodiments are not limited to this.

[0101] Therefore, the display panel 120 can be pulled out of the cover module 110 and pulled up.

[0102] Meanwhile, when the display panel 120 is pulled up to the outside of the cover module 110, such as Figure 5C As shown, when the first wire drum 153 of the first motor assembly 152 of the first drive system 150 rotates counterclockwise by the rotational force of the first motor 151, one end of the first drive wire 157 wound around the first winding portion 153a of the first wire drum 153 can be unwound from the first winding portion 153a, and the third region C of the first drive wire 157 can be moved from the first motor assembly 152 to the first pulley 155a.

[0103] The first region A of the first drive line 157 can move from the first pulley 155a to the second pulley 155b, and the fourth region D of the first drive line 157 can move from the second pulley 155b to the third pulley 155c.

[0104] The sixth region F of the first drive line 157 can be moved from the third pulley 155c to the fourth pulley 155d, and through this, the second region B of the first drive line 157 can be moved from the fourth pulley 155d to the fifth pulley 155e.

[0105] Meanwhile, the other end of the first drive line 157 can be wound around the second winding portion 153b of the first wire drum 153. Therefore, the fifth region E of the first drive line 157 can be moved from the fifth pulley 155e to the first motor assembly.

[0106] At this time, both the first region A and the second region B of the first drive line 157 can move downwards along the first direction (the -Y axis direction defined in the figure), and the first line fixing plate 159a and the second line fixing plate 159b fixed to the first region A and the second region B of the first drive line 157 can also move downwards. Accordingly, as Figure 5C As shown, the first bottom cover 121, to which the first line fixing plate 159a and the second line fixing plate 159b are assembled and fastened, can be moved downward, thereby allowing the display panel 120 equipped with the first bottom cover 121 to be lowered. However, the embodiments are not limited to this.

[0107] Therefore, the display panel 120 can be pulled down and embedded inside the cover module 110.

[0108] At this time, the first region A and the second region B of the first drive line 157 can be set to correspond to the two sides of the display panel 120, and a pair of first line fixing plates 159a and second line fixing plates 159b can be set on both sides of the display panel 120, so that the display panel 120 can be stably raised and lowered without being biased to either side.

[0109] It should be understood that the foregoing embodiments of the first drive system are exemplary and illustrative. The first drive system according to the exemplary embodiments of this disclosure is not limited to a specific structure or configuration such as the number and / or location of components.

[0110] The second drive system 160 may also be configured with the same or similar structure as the first drive system 150. Although not shown, the second drive system 160 may include a second motor assembly and a second wire assembly. The second motor assembly may include a second motor and a second wire drum. However, the implementation is not limited thereto.

[0111] The second wire assembly may include a second drive wire and a sixth, seventh, eighth, ninth, and tenth pulley. The second drive wire may extend from the third winding portion of the second wire drum of the second motor assembly and cross the sixth, seventh, eighth, ninth, and tenth pulleys, such that the other end of the second drive wire can be wound around the fourth winding portion of the second wire drum.

[0112] Additionally, a pair of third and fourth wire fixing plates can be fixed to the first and second regions of the second drive line, respectively, and the pair of third and fourth wire fixing plates can be assembled and fastened to the third and fourth sleeves, respectively. The first and second regions of the second drive line can move up and down, and accordingly, the light-shielding plate 130 can be raised and lowered along the longitudinal direction of the first and second regions of the second drive line together with the second bottom cover on which the third and fourth sleeves are installed. However, the implementation is not limited to this.

[0113] Therefore, the light shield 130 can also be embedded inside the cover module 110 or pulled out to the outside of the cover module 110.

[0114] The second drive system 160 raises or lowers the light shield 130, which can be done simultaneously with or separately from the display panel 120 according to the user's intention.

[0115] Alternatively, in the display device 100 according to an embodiment of the present disclosure, the display panel 120 and the light shield 130 can be raised or lowered separately by the first drive system 150 and the second drive system 160, respectively, to be extracted from or embedded in the cover module 110.

[0116] In particular, in the display device 100 according to the embodiments of the present disclosure, it is permissible to drive the first drive system 150 and the second drive system 160, which are used to raise and lower the display panel 120 and the light shield 130, respectively, based on the first drive line 157 and the second drive line, and it is possible to prevent or mitigate the limitation of reduced reliability caused by the drive belt.

[0117] That is, in the case of a belt drive system, when the belt is used for a long time, it may deform due to the reduction in belt tension. In this case, vibration noise will be generated due to belt vibration, or the display panel 120 may rise and fall unstablely.

[0118] Alternatively, raising and lowering the display panel 120 may also cause damage to the display panel 120.

[0119] Conversely, in the display device 100 according to an embodiment of the present disclosure, the first drive system 150 and the second drive system 160 may be configured to include a first drive line 157 and a second drive line formed of stainless steel with semi-permanent advantages, so that deformation of the first drive line 157 and the second drive line can be prevented or mitigated even after long-term use.

[0120] Furthermore, the first drive system 150 and the second drive system 160, which include the first drive line 157 and the second drive line according to the embodiments of this disclosure, can have a very simple structure and reduce or minimize the number of components, thereby also reducing the manufacturing cost of the display device 100.

[0121] Furthermore, since the first drive line 157 and the second drive line of the first drive system 150 and the second drive system 160 can be formed as closed curves, it can prevent or alleviate the display panel 120 or the light shield 130 from being pulled out from the first drive line 157 and the second drive line, respectively.

[0122] If the first drive line 157 and the second drive line are not formed as a closed curve, the display panel 120 or the light shield 130 can be pulled out from the first drive line 157 and the second drive line, thereby causing damage to the display panel 120 or the light shield 130 during the transport of the display device 100. However, in the display device 100 according to an embodiment of the present disclosure, the first drive line 157 and the second drive line can be configured to form a closed curve, which can also prevent the display panel 120 or the light shield from being pulled out from the first drive line 157 and the second drive line.

[0123] In particular, such as Figure 6 As shown, a tensioning mechanism, such as a turn buckle 158, can also be provided for adjusting the tension of the first drive line 157 and the second drive line.

[0124] The wire tensioner 158 is a component with screws at both ends in its longitudinal direction. The external thread at one end of the wire tensioner 158 is a right-hand thread, while the external thread at the other end of the wire tensioner 158 is a left-hand thread. When the component with the internal thread (i.e., the adjusting nut) rotates, the two external threads of the wire tensioner 158 can approach each other, and when the adjusting nut rotates in the opposite direction, the two external threads of the wire tensioner 158 can move away from each other.

[0125] Therefore, when the tension of the first drive line 157 and the second drive line is reduced by using the first drive line 157 and the second drive line for a long time, the tension of the first drive line 157 and the second drive line can be controlled by the tensioner 158.

[0126] At this time, the control printed circuit board 127a, the main board 127b and the power board 127c connected to the display panel 120 can be installed inside the cover module 110, and a cable penetration member 128 can also be provided to protect the cables used to connect the main board 127b and the control printed circuit board 127a and the power cables used to connect the power board 127c and the control printed circuit board 127a.

[0127] One end of the cable penetration member 128 can be mounted on the cover module 110, and the other end of the cable penetration member 128 can be connected to the first bottom cover 121, so that when the display panel 120 is raised and lowered relative to the cover module 110, the other end of the cable penetration member 128 can be raised and lowered together.

[0128] In the cable penetration member 128, a plurality of connecting members having empty spaces are rotatably connected to each other, allowing cables to pass through one end of the cable penetration member 128 from the other end. Therefore, when the display panel 120 is raised and lowered, the cable penetration member 128 can maintain a "U" shape with varying lengths on both sides, thereby allowing the cable to be raised and lowered without interference or damage to surrounding electronic components.

[0129] The display device 100 according to an embodiment of the present disclosure may further include a first lifting assist system 180 and a second lifting assist system 190. By controlling the speed at which the display panel 120 and the light shield 130 are raised and lowered from the cover module 110 by the first lifting assist system 180 and the second lifting assist system 190, rapid lowering of the display panel 120 and the light shield 130 when embedded inside the cover module 110 can be prevented or mitigated.

[0130] This will refer to Figure 7A and Figure 7B To describe in more detail.

[0131] Figure 7A and Figure 7B This is a perspective view illustrating the display panel and the first lifting assist system of a display device according to an embodiment of the present disclosure. Figure 7A This shows the display panel embedded inside the cover module and pulled down. Figure 7B This shows the display panel being pulled out of the cover module and pulled up.

[0132] As shown in the figure, a rotatable first bottom wheel 125 can be mounted on a first bottom cover 121 located at the lower end of the display panel 120, and a first lifting auxiliary system 180 can be disposed on the front side of the display panel 120 corresponding to the first bottom wheel 125.

[0133] The first lifting auxiliary system 180 may include a first lifting plate 181, a first gas spring 183 provided to the first lifting plate 181, a first 185a and a second line 185b connected to the first gas spring 183, and a first wheel bracket 187 and a second wheel bracket 189.

[0134] The first lifting plate 181 can be configured such that its longitudinal direction extends along the display panel 120 from... Figure 2 The cover module 110 is pulled out in the first direction (the +Y / -Y axis direction defined in the figure). The first wheel bracket 187 and the second wheel bracket 189 can be equipped on the upper end of the front surface of the first lifting plate 181, the rear surface of the first lifting plate 181 can face the display panel 120, and the first gas spring 183 can be disposed between the first wheel bracket 187 and the second wheel bracket 189.

[0135] The first round bracket 187 and the second round bracket 189 can penetrate the first lifting plate 181. The first round 187a and the second round 189a can protrude from the front surface of the first lifting plate 181, and the third round 187b and the fourth round 189b, which are interlocked with the first round 187a and the second round 189a respectively, can protrude from the rear surface of the first lifting plate 181.

[0136] The first gas spring 183 may be equipped with a first rod 183a that increases or decreases longitudinally along the first gas spring 183, and a first spring wheel 183b may be mounted on one end of the first rod 183a. A first line 185a may be wound around the first spring wheel 183b, with one end rotatably fixed to a first wheel 187a and the other end rotatably fixed to a second wheel 189a.

[0137] The second wire 185b can be wound around the first bottom wheel 125 mounted on the first bottom cover 121 of the display panel 120. At the same time, one end of the second wire 185b is rotatably fixed to the third wheel 187b protruding from the rear surface of the first lifting plate 181, and the other end of the second wire 185b is rotatably fixed to the fourth wheel 189b.

[0138] At this point, one end of the first thread 185a and one end of the second thread 185b can be fixed to the first reel 187a and the third reel 187b respectively, so as to be wound in opposite directions. The other end of the first thread 185a and the other end of the second thread 185b can be fixed to the second reel 189a and the fourth reel 189b respectively, so as to be wound in opposite directions.

[0139] The first gas spring 183 attempts to expand its volume according to the amount of gas filled within it, thereby enabling the first wire 185a and the second wire 185b to increase in volume through a force that expands their volume. Therefore, when one end of the first wire 185a is wound around the first reel 187a, one end of the second wire 185b can be unwound from the third reel 187b. When the other end of the first wire 185a is wound around the second reel 189a, the other end of the second wire 185b can be unwound from the fourth reel 189b.

[0140] Conversely, when one end of the first thread 185a unfolds from the first round 187a and the second round 189a respectively, one end of the second thread 185b can wrap around the third round 187b and the fourth round 189b respectively.

[0141] That is, such as Figure 7A As shown, when the display panel 120 is embedded in Figure 2 When the cover module 110 is in the pulled-down state, the first bottom cover 121 located at the lower end of the display panel 120 can be configured to correspond to the lower end of the first lifting assist system 180, and the second line 185b wound around the third wheel 187b and the fourth wheel 189b can be unfolded, thereby increasing the length of the second line 185b. Thus, the first line 185a can be wound around the first wheel 187a and the second wheel 189a.

[0142] Therefore, the first rod 183a of the first gas spring 183 can be embedded and disposed inside the first gas spring 183.

[0143] At this time, when the display panel 120 is moved from the first drive system 150... Figure 2 When the cover module 110 is pulled out (i.e., when the display panel 120 is to be changed from a pull-down state to a pull-up state), the display panel 120 can be pulled out from... Figure 2 The cover module 110 is pulled out, and the second line 185b can be wound around the third round 187b and the fourth round 189b, so that the first line 185a can be unfolded from the first round 187a and the second round 189a and become longer.

[0144] Additionally, in the first gas spring 183 of the first lifting assist system 180, the first rod 183a can extend in the +Y axis direction as defined in the figure, and thus can apply force to the first gas spring 183 in the +Y axis direction as defined in the figure.

[0145] Therefore, it is also possible to extend from the +Y axis direction defined in the diagram. Figure 2 A force is applied to the display panel 120 pulled out of the cover module 110. Since these forces can be applied to the first lifting assist system 180 and the display panel 120 in the same or substantially the same direction, the display panel 120 can be lifted more easily with a smaller force. Figure 2 It is extracted from the cover module 110.

[0146] On the contrary, such as Figure 7B As shown, when the display panel 120 is set to be pulled out... Figure 2 When the display panel 120 is moved outside the cover module 110 (i.e., when the display panel 120 is to be changed from an up state to a down state), the first bottom cover 121 provided at the lower end of the display panel 120 can be positioned to correspond to the upper end of the first lifting assist system 180L, and the second line 185b can be wound around the third wheel 187b and the fourth wheel 189b. Thus, the first line 185a can be unwound from the first wheel 187a and the second wheel 189a and become longer.

[0147] Therefore, the first rod 183a of the first gas spring 183 can extend to the outside of the first gas spring 183.

[0148] In this case, when attempting to embed the display panel 120 via the first drive system 150 Figure 2 When the cover module 110 is inside, the display panel 120 is embedded. Figure 2 Inside the cover module 110, the second line 185b can be unfolded from the third wheel 187b and the fourth wheel 189b, so that the first line 185a can be wrapped around the first wheel 187a and the second wheel 189a.

[0149] In addition, in the first gas spring 183 of the first lifting assist system 180, the first rod 183a can be gradually reduced from the state of the first rod 183a extending along the +Y axis direction defined in the figure, and can apply force to the first gas spring 183 in the +Y axis direction defined in the figure until the first rod 183a is fully inserted into the first gas spring 183.

[0150] Therefore, it can be embedded in the -Y axis direction defined in the figure. Figure 2 Force is applied to the display panel 120 in the cover module 110. Force can also be applied to the first lifting assist system 180 and the display panel 120 in the opposite direction.

[0151] At this time, since the force applied to the first lifting assist system 180 and the force applied to the display panel 120 are balanced with each other, the user can easily lower the display panel 120 at a stable speed.

[0152] Therefore, it is possible to prevent or mitigate the impact of embedding the display panel 120 into... Figure 2 During the process of lowering the cover module 110, the display panel 120 is rapidly lowered, which can also prevent or mitigate damage to the display panel 120.

[0153] here, Figure 2 The second lifting assist system 190 can also have the same or substantially the same structure as the first lifting assist system 180, so that when passing through Figure 2 The second drive system 160 in the middle makes Figure 2 When the light-shielding plate 130 in the middle is raised and lowered, it causes Figure 2 The light-shielding plate 130 in the middle Figure 2 The speed at which the cover module 110 is raised and lowered can be controlled by Figure 2 The second lifting assist system 190 in the middle is used for control. Therefore, it can prevent or alleviate [the problem]. Figure 2 The light-shielding plate 130 in the middle is in Figure 2 The light-shielding plate 130 is embedded in Figure 2 The cover module 110 is rapidly reduced during the process.

[0154] As described above, in the embodiments according to this disclosure Figure 2 The display device 100 in the middle can allow Figure 2 The display panel 120 and the light shield 130 are raised and lowered individually to allow for [the following to be adjusted / adjusted] from [the following to be adjusted / adjusted]: Figure 2 Extracted or embedded in the cover module 110 Figure 2 In the cover module 110. Therefore, through, such as including the first drive line 157 and the second drive line Figure 2 The simple structure and operation of the first drive system 150 and the second drive system 160, etc. Figure 2The display panel 120 and the light shield 130 can be raised and lowered from furniture, appliances, facilities, etc. (such as headboards, tables, or partitions) to improve space utilization, interior design, and style.

[0155] Furthermore, the transparent display panel 120 allows users to view images from both sides of the display panel 120, and the rear surface of the transparent display panel 120 can be further raised and lowered. Figure 2 The light-shielding plate 130 in the display panel 120 can increase the density of the image displayed through the transparent display panel 120. Therefore, the user can perceive the image displayed from the display panel 120 more clearly.

[0156] Specifically, in the display device 100 according to an embodiment of the present disclosure, it is used to raise and lower the display device respectively. Figure 2 The first driving system 150 and the second driving system 160 of the display panel 120 and the light shield 130 can be configured based on Figure 2 The first drive line 157 and the second drive line are driven, thereby reducing or preventing limitations caused by reliability degradation due to the drive belt. Because... Figure 2 The first drive system 150 and the second drive system 160 have a very simplified structure and reduce or minimize the number of components, thus also reducing costs. Figure 2 The manufacturing cost of the display device 100 in the middle.

[0157] In addition, due to Figure 2 The first drive system 150 and the second drive system 160 in Figure 2 The first drive line 157 and the second drive line form a closed curve, which can also prevent... Figure 2 The display panel 120 and the light shield 130 in the middle are from Figure 2 The first drive line 157 and the second drive line are pulled out.

[0158] Furthermore, according to the embodiments of this disclosure Figure 2 The display device 100 may also include Figure 2 The system includes a first lifting assist system 180 and a second lifting assist system 190, which can control the speed at which the display panel 120 and the light shield 130 are raised and lowered, thereby preventing or mitigating [the problem]. Figure 2 The display panel 120 and the light shield 130 are embedded in Figure 2 The cover module 110 is rapidly reduced during the process.

[0159] It will be apparent to those skilled in the art that various modifications and variations can be made to the display device of this disclosure without departing from the technical spirit or scope thereof. Therefore, this disclosure is intended to cover modifications and variations of this disclosure that fall within the scope of the appended claims and their equivalents.
