[0027] Throughout the accompanying drawings and detailed embodiments, unless otherwise described, the same reference numerals should be understood to refer to the same elements, features, and structures. The relative dimensions and descriptions of these elements may be exaggerated for clarity, illustration, and convenience. Detailed Implementation

[0028] Reference will now be made in detail to various aspects of this disclosure, exemplary embodiments of which are illustrated in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings to refer to the same or similar parts.

[0029] The advantages and features of this disclosure, and methods of implementing them, will be illustrated by the following exemplary embodiments described with reference to the figures. However, this disclosure may be implemented in different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided to make this disclosure thorough and complete enough to assist those skilled in the art in fully understanding its scope. Furthermore, this disclosure is limited only by the scope of the claims.

[0030] The shapes, dimensions, areas, ratios, angles, and quantities disclosed in the accompanying drawings for describing embodiments of the present disclosure are merely examples, and therefore, the present disclosure is not limited to the details shown. The same reference numerals always denote the same elements. In the following description, detailed descriptions of relevant known functions or configurations will be omitted or provided briefly when it is determined that such detailed descriptions would unnecessarily obscure important points of the present disclosure. Where the terms “comprising,” “having,” and “including” described in the present disclosure may be used, an additional part may be added unless more restrictive terms such as “only” are used. Singular terms may include plural forms unless otherwise indicated.

[0031] When interpreting a component, the component is interpreted as including a range of errors or tolerances, even if there is no explicit description of such a range of errors or tolerances.

[0032] In the description of various embodiments of this disclosure, where the positional relationship between two parts is described using terms such as “above,” “over,” “below,” “on top,” “below,” “beside,” and “adjacent,” one or more other parts may be located between the two parts unless more restrictive terms such as “immediately following” or “directly” are used.

[0033] When describing temporal relationships, for example, when the time sequence is described as "after", "following", "next" and "before", it may include cases that are not consecutive, unless more restrictive terms such as "exactly", "immediately" or "directly" are used.

[0034] In describing the elements of this disclosure, the terms “first,” “second,” “A,” “B,” “(a),” “(b),” etc., may be used. These terms may be used only to distinguish one element from another, and the nature, order, basis, sequence, or number of corresponding elements shall not be limited by these terms. Expressions describing an element as “connected,” “joined,” or “adhered” to another element or layer should be understood to mean that an element or layer may be directly connected or adhered to another element or layer, or indirectly connected or adhered to another element or layer, and that one or more intermediate elements or layers are “set” or “inserted” between elements or layers, unless otherwise stated.

[0035] The term “at least one” should be understood to include any and all combinations of one or more of the associated listed items. For example, “at least one of the first, second and third items” means combinations of all three listed items, combinations of any two of the three items, and each individual item, the first, second or third item.

[0036] Features of the various embodiments of this disclosure may be coupled or combined with each other in part or in whole, and may interoperate with each other in various ways and be technically driven, as will be fully understood by those skilled in the art. Embodiments of this disclosure may be performed independently of each other, or may be performed together in a mutually related relationship.

[0037] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which the exemplary embodiments pertain. It will also be understood that terms such as those defined in commonly used dictionaries shall be interpreted as having a meaning consistent with their meaning in the context of the relevant field and shall not be interpreted in an idealized or overly formal sense unless expressly defined herein.

[0038] In the following, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Furthermore, for ease of description, the scale, size, and thickness of each element shown in the drawings may differ from their actual scale, size, and thickness, and therefore, the elements shown are not limited to their specific scale, size, and thickness as shown in the drawings.

[0039] Figure 1A This is a perspective view schematically showing a display device with the display panel in an embedded state according to an embodiment of the present disclosure, and Figure 1B , Figure 1C and Figure 1D This is a perspective view schematically showing a display device with the display panel in various withdrawn states according to embodiments of the present disclosure.

[0040] like Figure 1A As shown, the display device 100 may include a display panel 120 embedded in the cover module 110 (see Figure 120). Figure 1B The cover module 110 can be attached to furniture, vehicles, appliances, and facilities such as walls, headboards, tables, or partitions, or anything with enough space to receive the cover module 110.

[0041] like Figure 1B As shown, the display panel 120, which is pulled down and embedded in the cover module 110, can be pulled up and completely pulled out of the cover module 110.

[0042] Here, the display panel 120 according to the embodiments of this disclosure can be formed of a transparent display panel, allowing a user to see objects or images located on opposite sides through the display panel 120. Furthermore, the user can view images from both one side and the other side of the display panel 120. However, the embodiments are not limited to this. For example, the display panel 120 can also be formed of an opaque display panel or a semi-transparent display panel.

[0043] According to embodiments of this disclosure, when the display panel 120 is formed of a transparent display panel, such as Figure 1CAs shown, the light-blocking plate 130 can be further pulled out from the cover module 110 to the rear surface of the display panel 120. However, the implementation is not limited to this. For example, the light-blocking plate 130 can be omitted or can be provided separately without being embedded in the cover module 110.

[0044] By preventing objects or images located on opposite sides of the display panel 120 from being transmitted through the light-blocking plate 130, the concentration 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.

[0045] For example, transparent display panels can function as transparent electronic devices to achieve information recognition, information processing, and information display, thereby solving the spatial and visual limitations of existing electronic devices.

[0046] 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 have no limitation in contrast in dark environments, but their disadvantage lies in reduced contrast in typical well-lit environments.

[0047] Therefore, the light blocking plate 130 can be further extracted from the cover module 110 to the rear surface of the display panel 120, thereby enabling a light blocking mode for blocking light and a transmission mode for transmitting light, so as to prevent or reduce the reduction of the contrast of the transparent display panel.

[0048] In addition, such as Figure 1D As shown, in the display device 100 according to an embodiment of the present disclosure, only a portion of the display panel 120 can be extracted from the cover module 110, and the remaining portion (e.g., most of) of the display panel 120 can be embedded in the cover module 110, thereby also realizing an always-on display (AOD) device.

[0049] The AOD device can display AOD data that can be viewed by the user at any time, even when no image is displayed on the display panel 120. The AOD data may include, but is not limited to, information about the date, time, weather, event reminders, temperature, etc., and the AOD data can be changed in various ways according to user settings or automatically.

[0050] Figure 2 This is an exploded perspective view showing a display device according to an embodiment of the present disclosure. Figure 3A This is a perspective view showing a display panel, a first driving system, and a second driving system according to embodiments of the present disclosure. Figure 3B This illustrates an embodiment according to the present disclosure. Figure 3A A three-dimensional diagram of the operation of the first drive system.

[0051] 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 blocking plate 130, a first driving system 150 and a second driving system 160, a pair of guide rails 171a and 171b, and a first lifting auxiliary system 180 and a second lifting auxiliary system 190, but the embodiments of the present disclosure are not limited thereto.

[0052] The cover module 110 may have a box shape, accommodating 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 blocking plate 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 blocking plate 130.

[0053] 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 use an OLED, which is a representative of flexible display devices that can maintain display performance even when bent like paper.

[0054] OLEDs are self-emissive devices and can be lightweight and thin because they do not require backlighting as used in liquid crystal displays, which are non-emissive devices.

[0055] Compared to LCD displays, OLEDs offer wider viewing angles, higher contrast ratios, and lower power consumption. Furthermore, OLEDs are driven by low-voltage direct current (DC) and have a fast response time. Additionally, because their components are solid-state, OLEDs are more resistant to external shocks and can be used over a wide temperature range.

[0056] In particular, due to its simple manufacturing process, OLED has the advantage of significantly lower production costs compared to liquid crystal display devices.

[0057] 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. However, the implementation is not limited to this. The display panel 120 made of OLED may also include only one substrate without a bonding process.

[0058] Although not shown, a driving thin-film transistor can be formed on a first substrate for each pixel region, and a first electrode connected to each driving thin-film transistor, an organic light-emitting layer on the first electrode and emitting light of a specific color, and a second electrode on the organic light-emitting layer can be provided for each pixel region.

[0059] Organic light-emitting layers can represent red, green, and blue. The colors they can represent are not limited to these. Typically, individual organic materials emitting red, green, or blue light can be patterned and used for each pixel.

[0060] 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.

[0061] 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. For example, the background behind the display panel 120 can be transmitted through the transmissive region of the display panel 120, which is like transparent glass, and can be provided to the user.

[0062] In addition, light-emitting diodes can be placed in the light-emitting area to display image information implemented by the display panel 120.

[0063] The first bottom cover 121 can be mounted on 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 upward and withdrawn from the cover module 110. In one embodiment, the first direction is the +Y axis direction as defined in the figures. Alternatively, the first direction can be any of the applicable directions, such as a horizontal direction.

[0064] When the display panel 120 is removed from or embedded in 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.

[0065] A pair of first lead screw nuts 123a and second lead screw nuts 123b can be disposed and installed at both ends of the first bottom cover 121 and can be connected to the first drive system 150. Therefore, the first lead screw nuts 123a and second lead screw nuts 123b can be disposed at both ends of the display panel 120. The number and position of the lead screw nuts are not limited thereto.

[0066] Although not shown in the figure, the second bottom cover can also be mounted on the lower end of the light blocking plate 130 disposed on the rear surface of the display panel 120. The second bottom cover can be raised and lowered together with the light blocking plate 130, and can be disposed inside the cover module 110.

[0067] A pair of third and fourth lead screw nuts may be disposed at both ends of the second bottom cover and may be connected to the second drive system 160, but the embodiments disclosed herein are not limited thereto. For example, the second bottom cover may be connected to the first drive system 150 or other drive systems not mentioned herein, and the second drive system 160 may operate simultaneously or asynchronously with the first drive system 150.

[0068] A pair of guide rails 171a and 171b may be disposed at both ends of the display panel 120 and the light blocker 130 in a second direction (e.g., a lateral direction) perpendicular to a first direction in which the display panel 120 and the light blocker 130 are pulled out. When the display panel 120 and the light blocker 130 are raised and lowered from the cover module 110, the pair of guide rails 171a and 171b may respectively support and guide both ends of the display panel 120 and the light blocker 130.

[0069] The first driving system 150 and the second driving system 160 can be respectively disposed below the display panel 120 and the light blocking plate 130. The first driving system 150 and the second driving system 160 can be disposed above the plate 115 forming the bottom surface of the cover module 110.

[0070] The first drive system 150 may include a first motor assembly 151, a first drive pulley 153 connected to a rotating shaft of the first motor assembly 151, and a pair of first driven pulleys 155a and second driven pulleys 155b connected to the first drive pulley 153 via a first drive belt 157.

[0071] The first driven pulley 155a and the second driven pulley 155b can be respectively disposed at both ends of the plate 115 along the longitudinal direction of the plate 115. The first linear screw 158a and the second linear screw 158b can be assembled with the first driven pulley 155a and the second driven pulley 155b to rotate together with the first driven pulley 155a and the second driven pulley 155b according to their rotation.

[0072] Here, the first drive pulley 153, the first driven pulley 155a, and the second driven pulley 155b can be coaxially positioned and connected to each other via the first drive belt 157. Therefore, the first drive pulley 153, which is rotated by the first motor assembly 151, can rotate the first driven pulley 155a and the second driven pulley 155b by reducing the number of rotations at a predetermined transmission ratio, and the first linear screw 158a and the second linear screw 158b can rotate according to the rotation of the first driven pulley 155a and the second driven pulley 155b.

[0073] At this time, a pair of first lead screw nuts 123a and second lead screw nuts 123b installed on the first bottom cover 121 of the display panel 120 can be screwed onto the first linear screw 158a and the second linear screw 158b, respectively. The pair of first lead screw nuts 123a and second lead screw nuts 123b can transmit the power used to raise and lower the display panel 120 to the first bottom cover 121.

[0074] For example, a pair of first lead screw nuts 123a and second lead screw nuts 123b can be screwed onto the first linear screw 158a and the second linear screw 158b respectively, so that the first lead screw nuts 123a and the second lead screw nuts 123b can be raised and lowered in the longitudinal direction of the first linear screw 158a and the second linear screw 158b according to the rotation of the first linear screw 158a and the second linear screw 158b.

[0075] Since the first lead screw nut 123a and the second lead screw nut 123b rise and fall in the longitudinal direction of the first linear screw 158a and the second linear screw 158b, the display panel 120 can also rise and fall in the longitudinal direction of the first linear screw 158a and the second linear screw 158b together with the first bottom cover 121 on which the first lead screw nut 123a and the second lead screw nut 123b are installed.

[0076] For example, the first linear screw 158a and the second linear screw 158b can be rotated via the first drive belt 157 by the driving force of the first motor assembly 151, and the first lead screw nut 123a and the second lead screw nut 123b can be raised and lowered by the rotation of the first linear screw 158a and the second linear screw 158b. Therefore, the display panel 120 can also be raised and lowered in the longitudinal direction of the first linear screw 158a and the second linear screw 158b together with the first bottom cover 121 on which the first lead screw nut 123a and the second lead screw nut 123b are mounted.

[0077] Therefore, the display panel 120 can be pulled down and embedded into the cover module 110, or it can be pulled up and pulled out of the cover module 110.

[0078] At this time, the first linear screw 158a and the second linear screw 158b used to raise and lower the first lead screw nut 123a and the second lead screw nut 123b along the longitudinal direction can be respectively arranged at both ends of the plate 115 in a second direction (e.g., the lateral direction) perpendicular to the first direction in which the display panel 120 and the light blocking plate 130 are pulled out, so that the first lead screw nut 123a and the second lead screw nut 123b can be raised and lowered stably without deviating to either side. The number and position of the first linear screw 158a and the second linear screw 158b are not limited thereto.

[0079] Alternatively, the second drive system 160 may be configured to have a structure similar to that of the first drive system 150. The second drive system 160 may include a second motor assembly 161, a second drive pulley 163 connected to the rotating shaft of the second motor assembly 161, and a pair of third driven pulleys 165a and fourth driven pulleys 165b connected to the second drive pulley 163 via a second drive belt 167.

[0080] The second drive pulley 163, the third driven pulley 165a, and the fourth driven pulley 165b can be coaxially positioned and connected to each other via the second drive belt 167. For example... Figure 3A and Figure 3B As shown, the third linear screw 168a and the fourth linear screw 168b can be respectively mounted on the third driven pulley 165a and the fourth driven pulley 165b. Although not shown in the figure, a pair of third and fourth lead screw nuts mounted on the second bottom cover of the light blocking plate 130 can be screwed onto the third linear screw 168a and the fourth linear screw 168b respectively.

[0081] Therefore, the third driven pulley 165a and the fourth driven pulley 165b can be rotated by the second drive pulley 163 rotated by the second motor assembly 161, and the third linear screw 168a and the fourth linear screw 168b can be rotated according to the rotation of the third driven pulley 165a and the fourth driven pulley 165b.

[0082] Furthermore, based on the rotation of the third linear screw 168a and the fourth linear screw 168b, the third lead screw nut and the fourth lead screw nut can be raised and lowered along the longitudinal direction of the third linear screw 168a and the fourth linear screw 168b, so that the light blocking plate 130 can also be raised and lowered together with the second bottom cover along the longitudinal direction of the third linear screw 168a and the fourth linear screw 168b.

[0083] The raising or lowering of the light blocking plate 130 via the second drive system 160 can be performed simultaneously with the display panel 120, or separately from the display panel 120 according to the user's intention.

[0084] Alternatively, in the display device 100 according to an embodiment of the present disclosure, the display panel 120 and the light blocking plate 130 can be raised or lowered independently by the first driving system 150 and the second driving system 160, respectively, to be extracted from or embedded in the cover module 110.

[0085] Therefore, by simply pulling the display panel 120 out of the cover module 110 via the first drive system 150, the user can view the image on both sides of the display panel 120. Furthermore, if necessary, the light blocking plate 130 can be further pulled onto the rear surface of the transparent display panel 120 via the second drive system 160, thereby improving the focus of the image realized by the display device 100.

[0086] At this time, although not shown, the control printed circuit board, motherboard and power board connected to the display panel 120 can be installed in the cover module 110, and cable penetration members can be further provided to protect the cables for connecting the motherboard and the control printed circuit board and the power cables for connecting the power board and the control printed circuit board.

[0087] One end of the cable penetration member can be mounted on the cover module 110, while the other end of the cable penetration member can be connected to at least one of the first lead screw nut 123a and the second lead screw nut 123b, 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 can be raised and lowered together with the first bottom cover 121.

[0088] In the cable penetration member, multiple connecting members with empty spaces can be rotatably connected to each other, allowing cables to pass through from one end of the cable penetration member to the other. Therefore, when the display panel 120 is raised and lowered, the cable penetration member can maintain a "U" shape, wherein the lengths on both sides of the cable penetration member are changed, thereby allowing the cable to be raised and lowered without interference or damage to surrounding electronic components.

[0089] 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 blocking plate 130 are raised and lowered from the cover module 110 via the first lifting assist system 180 and the second lifting assist system 190, the rapid lowering of the display panel 120 and the light blocking plate 130 when embedded in the cover module 110 can be prevented.

[0090] This will refer to Figures 4A to 4C as well as Figure 5A and Figure 5B To describe in more detail.

[0093] As shown in the figure, the rotatable first bottom wheel 125 can be installed on the first bottom cover 121 mounted at the lower end of the display panel 120, and the first lifting auxiliary system 180 can be arranged on the front side of the display panel 120 corresponding to the first bottom wheel 125.

[0094] The first lifting auxiliary system 180 may include a first lifting plate 181, a first gas spring 183 assembled to the first lifting plate 181, a first wire 185a and a second wire 185b connected to the first gas spring 183, and a first wheel bracket 187 and a second wheel bracket 189.

[0095] The first lifting plate 181 can be configured to extend along the display panel 120 from... Figure 2 The first direction in which the cover module 110 is pulled out has its longitudinal direction. The first wheel bracket 187 and the second wheel bracket 189 can be mounted at the upper end of the front surface of the first lifting plate 181 based on the rear surface of the first lifting plate 181 that can face the rear surface of the display panel 120, and the first gas spring 183 can be arranged between the first wheel bracket 187 and the second wheel bracket 189.

[0096] 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.

[0097] The first gas spring 183 may be fitted with a first rod 183a that increases or decreases along the longitudinal direction of the first gas spring 183 (e.g., the +Y or -Y direction), and a first spring wheel 183b may be mounted on one end of the first rod 183a. The first rod 183a can move along the longitudinal direction of the first gas spring 183, thereby increasing or decreasing its exposed length. A first thread 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.

[0098] The second thread 185b can be wound around the first bottom wheel 125 mounted on the first bottom cover 121 of the display panel 120, while one end of it is rotatably fixed to the third wheel 187b protruding from the rear surface of the first lifting plate 181, and the other end of it is rotatably fixed to the fourth wheel 189b.

[0099] At this point, one end of the first thread 185a and the second thread 185b can be fixed to the first reel 187a and the third reel 187b respectively, so that they are wound in opposite directions. The other ends of the first thread 185a and the second thread 185b can be fixed to the second reel 189a and the fourth reel 189b respectively, so that they are wound in opposite directions.

[0100] The first gas spring 183 attempts to expand its volume according to the amount of gas it is filled with, such that the first gas spring 183 can increase the volume of the first wire 185a and the second wire 185b by applying force. 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.

[0101] Conversely, when one end of the first thread 185a unfolds from the first reel 187a and the second reel 189a respectively, one end of the second thread 185b can be wrapped around the third reel 187b and the fourth reel 189b respectively.

[0102] The first gas spring 183, the first wire 185a, and the second wire 185b can be organically connected to each other, so that the first lifting auxiliary system 180 can control the speed of raising and lowering the display panel 120 by the repulsive force of the first gas spring 183.

[0103] For example, during the process of increasing or decreasing the first rod 183a of the first gas spring 183, since a force can be applied in the +Y axis direction defined in the figure, the force can be balanced with the force applied to the display panel 120, allowing the user to easily raise and lower the display panel at a stable speed.

[0104] Reference Figure 5A and 5B The operation of the display panel 120 and the first lifting auxiliary system 180 is described in detail. Figure 5A As shown, in the pull-down state, when the display panel 120 is embedded in... Figure 2 When the cover module 110 is installed, the first bottom cover 121, which is assembled at the lower end of the display panel 120, can be configured to correspond to the lower end of the first lifting auxiliary system 180, and the second line 185b, which is wound on 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 on the first wheel 187a and the second wheel 189a.

[0105] Therefore, the first rod 183a of the first gas spring 183 can be embedded and disposed within the first gas spring 183.

[0106] At this time, when the display panel 120 will be driven by the first drive system 150 from... Figure 2 When the cover module 110 is pulled out, for example, when the display panel 120 is removed from the cover module 110. Figure 5A The dropdown state is set to Figure 5B When in the pull-up state, the display panel 120 can be viewed 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.

[0107] Furthermore, in the first gas spring 183 of the first lifting assist system 180, the first rod 183a can extend in the -Y axis direction defined in the figure, and therefore the force can be applied to the first gas spring 183 in the +Y axis direction defined in the figure.

[0108] Therefore, the force can also be applied along the +Y axis direction defined in the attached figure to the direction from which the force will be applied. Figure 2 The display panel 120 is pulled out from 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 more easily lifted from the cover module 110. Figure 2 It is extracted from the cover module 110.

[0109] On the contrary, such as Figure 5B As shown, when the display panel 120 is set to be pulled out Figure 2 When the cover module 110 is outside, for example, when the display panel 120 is removed from the cover module 110. Figure 5B The pull-up state is set to Figure 5AIn the pulled-down state, the first bottom cover 121, mounted at the lower end of the display panel 120, can be positioned to correspond to the upper end of the first lifting assist system 180. 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.

[0110] Therefore, the first rod 183a of the first gas spring 183 can extend to the outside of the first gas spring 183.

[0111] 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 inserted, the display panel 120 will be embedded. Figure 2 Within the cover module 110, the second thread 185b can be unfolded from the third wheel 187b and the fourth wheel 189b, so that the first thread 185a can be wrapped around the first wheel 187a and the second wheel 189a.

[0112] Furthermore, in the first gas spring 183 of the first lifting assist system 180, the first rod 183a can be gradually reduced from the state in which the first rod 183a extends in the -Y axis direction defined in the figure, and a force can be applied 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.

[0113] At the same time, it can be embedded in the -Y axis direction defined in the figure. Figure 2 A force is applied to the display panel 120 in the cover module 110. Therefore, the force can be applied in opposite directions to the first lifting assist system 180 and the display panel 120.

[0114] 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.

[0115] Therefore, it is possible to prevent embedding in the display panel 120 Figure 2 During the process of lowering the display panel 120 into the cover module 110, the display panel 120 is rapidly lowered, and damage to the display panel 120 can also be prevented.

[0116] here, Figure 2 The second lifting assist system 190 can also have the same structure as the first lifting assist system 180, so that when passing through Figure 2 The second drive system 160 lift and lower Figure 2 When the light blocking plate is 130, it can pass through Figure 2 The second lifting auxiliary system 190 controls from Figure 2 The cover module 110 is raised and lowered. Figure 2 The speed of the light blocking plate is 130. Therefore, it can prevent the light from being blocked. Figure 2 Light blocking plate 130 embedded Figure 2 During the process of covering module 110 Figure 2 The light blocking plate 130 was rapidly lowered.

[0117] As described above, in the embodiments according to this disclosure Figure 2 The display device 100 can allow Figure 2 The display panel 120 and the light blocking plate 130 are connected by means such as Figure 2 The simple structure and operation of the first drive system 150 and the second drive system 160 allow for raising and lowering of furniture, appliances and facilities such as headboards, tables or partitions, thereby improving space utilization, internalization and design.

[0118] Furthermore, the transparent display panel 120 allows users to view images from both sides of the display panel 120, and the panel can be further raised and lowered on its rear surface. Figure 2 The light-blocking plate 130 enhances the focus 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.

[0119] Furthermore, according to the embodiments of this disclosure Figure 2 The display device 100 may also include Figure 2 The first lifting auxiliary system 180 and the second lifting auxiliary system 190 are controllable. Figure 2 The speed at which the display panel 120 and the light blocking plate 130 are raised and lowered, therefore, when... Figure 2 The display panel 120 and the light blocking plate 130 are embedded Figure 2 During the process within the cover module 110, it can prevent Figure 2 The display panel 120 and the light blocking plate 130 are rapidly lowered.

[0120] 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 concept 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.
