Description

Technical Field

[0001] This disclosure relates to a display device, and more specifically, to a display device including a display panel that can be raised or lowered. Background Technology

[0002] In recent years, with the advent of the fully mature information age, there has been a growing interest in information displays capable of processing and displaying large amounts of information. In response, various flat panel display devices have been developed and have become a focus of attention.

[0003] Specific examples of flat panel display devices include, but are not limited to, liquid crystal display (LCD) devices, plasma display panel (PDP) devices, field emission display (FED) devices, electroluminescent display (ELD) devices, and organic light-emitting diode (OLED) display devices. Flat panel display devices exhibit excellent performance in terms of thinness, light weight, and low power consumption, and have rapidly replaced cathode ray tube (CRT) display devices.

[0004] In the process of developing technologies to realize these display devices in recent years, in addition to technologies for displaying images, technologies for realizing designs expected by consumers are also needed for display devices.

[0005] In recent times, in the further development of the technology used to realize such display devices, in addition to the technology for displaying images, there is also a need for technology to realize various display devices that consumers expect.

[0006] Among these technologies, research is actively underway to enable various types of display devices in which display panels are connected to structures such as furniture, appliances, vehicles, and facilities, offering advantages in space utilization, interior design, and aesthetics.

[0035] In describing the elements of this disclosure, the terms “first,” “second,” “A,” “B,” “(a),” “(b),” etc., may be used. These terms may only be used 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 expressing that an element is “connected,” “joined,” or “adhered” to another element or layer should be understood to mean that the element or layer may not only be directly connected or adhered to another element or layer, but also indirectly connected or adhered to another element or layer in the presence of one or more intermediate elements or layers “set” or “inserted” between the aforementioned elements or layers, unless otherwise stated.

[0036] The term "at least one" should be understood to include any and all combinations of one or more related listed items. For example, "at least one of the first, second, and third items" means a combination of all three listed items, a combination of any two of the three items, and each of the first, second, or third items individually.

[0037] Features of the various embodiments of this disclosure may be linked or combined with each other in part or in whole, and may interoperate with each other and be technically driven in various ways, 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 an interdependent relationship.

[0038] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which the exemplary embodiments pertain. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent, for example, with their meaning in the context of the relevant field, and that unless explicitly defined herein, these terms will not be interpreted in an idealized or overly formal sense.

[0039] 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.

[0040] 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, and 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.

[0041] like Figure 1A As shown, the display device 100 may include a display panel 120 (not shown) embedded in the cover module 110. The cover module 110 may be connected to furniture, appliances, vehicles, facilities, etc., such as headboards, tables, or partitions, but embodiments of this disclosure are not limited thereto.

[0042] 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.

[0043] 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.

[0044] When the display panel 120 is formed of a transparent display panel, such as Figure 1CAs shown, the light shield 130 can be further pulled out from the cover module 110 to the rear surface of the display panel 120.

[0045] By preventing or mitigating the transmission of objects or images located on opposite sides of the display panel 120 through the light shield 130, the focus of the image realized through the display panel 120 can be improved. Therefore, the user can perceive the image realized from the display panel 120 more clearly.

[0046] 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 constraints of existing electronic devices.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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, for example, but not limited to, information about date, time, weather, event alarms, temperature, etc., and the AOD data can be changed according to the user's settings.

[0051] Figure 2A This is an exploded perspective view illustrating a display device according to an embodiment of the present disclosure. Figure 2B This is a perspective view illustrating a modular display device according to an embodiment of the present disclosure, and Figure 2C This is a perspective view illustrating a display device in which a display panel is pulled up from a cover module according to an embodiment of the present disclosure.

[0052] Figure 3A This is a perspective view illustrating the arrangement of the sleeve and guide rod according to an embodiment of the present disclosure, and Figure 3BThis is a perspective view illustrating the arrangement of guide rails according to an embodiment of the present disclosure.

[0053] Figure 4A This is a perspective view illustrating a first drive system according to an embodiment of the present disclosure. Figure 4B and Figure 4C This is a front view illustrating the operation of a first drive system according to an embodiment of the present disclosure, and Figure 4D This is a perspective view illustrating a first rigid chain according to an embodiment of the present disclosure.

[0054] 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 driving system 150 and a second driving system 160, a pair of guide rails 170a and 170b, 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] In particular, OLEDs have the advantage of significantly reducing production costs compared to liquid crystal displays due to the simplified manufacturing process.

[0060] 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.

[0061] 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.

[0062] Organic light-emitting layers can represent red, green, and blue. Typically, individual organic materials emitting red, green, or blue light can be patterned and used for each pixel.

[0063] 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.

[0064] 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 outside the display panel 120 may be transmitted through the transmissive region of the display panel 120 like transparent glass and may be provided to the user.

[0065] In addition, light-emitting diodes can be placed in the light-emitting area to display image information implemented by the display panel 120.

[0066] 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 up and withdrawn from the cover module 110. 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.

[0067] 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.

[0068] The first bottom cover 121 can be connected to the first drive system 150.

[0069] like Figure 3AAs 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., +Y or -Y direction) of the first guide rods 117a and 117b (e.g., the vertical direction in the context of the drawings).

[0070] 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.

[0071] In this case, the first guide rod 117a and the second guide rod 117b may also include a stop for limiting the lifting height of the first sleeve 123a and the second sleeve 123b, but the embodiments of this disclosure are not limited thereto.

[0072] Although not shown in the figures, the 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 may be raised and lowered together with the light shield 130 and disposed inside the cover module 110, but the embodiments of this disclosure are not limited thereto.

[0073] The second bottom cover may be connected to the second drive system 160, but the embodiments of this disclosure 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.

[0074] 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 installed together with the light-shielding plate 130 along the third guide rod 118a and fourth guide rod 118b fixed to the cover module 110 (see...). Figure 2A The longitudinal direction (e.g., the vertical direction in the context of the figures) rises and falls.

[0075] A pair of guide rails 170a and 170b can be disposed at both ends of the display panel 120 and the light shield 130 in a second direction (e.g., a lateral direction) relative to the first direction in which the display panel 120 and the light shield 130 are pulled out. Figure 3BAs 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.

[0076] 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.

[0077] The first drive system 150 and the second drive system 160, respectively connected to the first bottom cover 121 and the second bottom cover, can be disposed below the display panel 120 and the light shield 130. The first drive system 150 and the second drive system 160 can be disposed above the plate 115 forming the bottom surface of the cover module 110.

[0078] like Figure 4A As shown, the first drive system 150 may include a first motor assembly 153 and a first chain assembly 156, and the first chain assembly 156 may include a first sprocket 157 that receives rotation of the first motor assembly 153 and a first rigid chain 159 that engages with the first sprocket 157 to switch its direction of movement by rotation of the first sprocket 157.

[0079] Here, the first motor assembly 153 can rotate the first sprocket 157 and may include an electric motor and a reducer. The electric motor can provide rotational force by using electricity and can be selected from different types such as servo motors, stepper motors, etc.

[0080] The first motor assembly 153 can precisely control the extension length of the first rigid chain 159 that engages with the first sprocket 157 by precisely controlling the rotation of the first sprocket 157.

[0081] The first motor assembly 153 may further include a first spur gear 153a connected to a rotatable shaft of the motor 151, a second spur gear 153b engaging with the first spur gear 153a, and a third spur gear 153c having a rotating shaft connected to the first sprocket 157. The first motor assembly 153 may reduce the number of rotations of the first spur gear 153a, the second spur gear 153b, and the third spur gear 153c at a predetermined gear ratio to transmit rotational force to the first sprocket 157, thereby causing the first sprocket 157 to rotate.

[0082] The first sprocket 157 may be rotatably disposed within the first guide plate 154 located on one side of the first motor assembly 153. The first rigid chain 159 may be connected around the first sprocket 157, and the first rigid chain 159 may move in the vertical direction by the rotation of the first sprocket 157.

[0083] Alternatively, the first track 154a can also be disposed inside the first guide plate 154. The first guide plate 154 can be used to limit the movement trajectory of the first rigid chain 159.

[0084] For example, when the first rigid chain 159 moves due to the rotation of the first sprocket 157, the first rigid chain 159 can move along the first track 154a within the first guide plate 154. Figure 4C As shown, the first rigid chain 159 can be coiled along the first track 154a and housed in the first guide plate 154, or as... Figure 4B As shown, the first rigid chain 159 can be pushed out from the first guide plate 154 by the rotation of the first sprocket 157, and can move vertically along a straight line.

[0085] Here, refer to a more detailed description relative to the first rigid chain 159. Figure 4D The first rigid chain 159 may have a structure in which multiple linking units are connected in series so as to bend between adjacent linking units.

[0086] A link unit may have a configuration in which a pair of link plates 159a facing each other are connected to each other by a hinge 159b. A rigid chain 159 may have a configuration in which multiple link units having such configurations are connected to each other by hinges 159b.

[0087] The support roller 159c can be mounted on the corresponding hinge 159b exposed outside the link plate 159a. The support rollers 159c of adjacent link units can be positioned close to each other.

[0088] As described above, the linking units can be connected to each other by shielding each other via hinge 159b, so that the support rollers 159c are close to each other. Therefore, when the first rigid chain 159 rises in a straight line, bending of the first rigid chain 159 can be prevented, so that the first rigid chain 159 can remain linear in the vertical direction.

[0089] One end of the link unit can be spaced apart from each other based on the hinge 159b near the first sprocket 157, so that the rigid chain 159 can form a curve near the first sprocket 157, while the first rigid chain 159 remains linear in its vertical portion.

[0090] For example, in the first rigid chain 159, multiple linking units can be segmented and bent to form curves, or the support rollers 159c of multiple linking units can be brought close to each other to move in a straight line along the longitudinal direction.

[0091] Therefore, by rotating the first sprocket 157, the first rigid chain 159 can be curved along the first track 154a and accommodated inside the first guide plate 154 (see...). Figure 4CAlternatively, the first rigid chain 159 can be extended from the first guide plate 154 and can move vertically along a straight line (see...). Figure 4B ).

[0092] One end of the first rigid chain 159 can be connected to the first bottom cover 121 of the display panel 120, so that the first rigid chain 159 can support the first bottom cover 121 and the first bottom cover 121 can be raised and lowered by the rotation of the first sprocket 157.

[0093] Therefore, the display panel 120 can also be raised and lowered together with the first bottom cover 121, and the display panel 120 can be pulled down and embedded inside the cover module 110 and pulled up and pulled out to the outside of the cover module 110.

[0094] In the first drive system 150, one end of the first rigid chain 159 may be connected, for example, to the center of the lower end of the first bottom cover 121 or to a region adjacent to the center of the lower end, so that the raised and lowered display panel 120 can be easily kept horizontal, but the embodiments of this disclosure are not limited thereto.

[0095] Alternatively, the second drive system 160 may be configured to have a structure similar to that of the first drive system 150. Although not shown, the second drive system 160 may include a second motor assembly and a second chain assembly. The second chain assembly may include a second sprocket that receives rotation from the second motor assembly and a second rigid chain that engages with the second sprocket and is capable of moving in the vertical direction by the rotation of the second sprocket.

[0096] One end of the second rigid chain can be connected to the second bottom cover of the light shield 130, and the second rigid chain can support the second bottom cover so that the second bottom cover can be raised and lowered by the rotation of the second sprocket.

[0097] By rotating the second sprocket, the second rigid chain can be coiled in a curve along the second track and housed in the second guide plate, or the second rigid chain can be pushed out from the second guide plate and can move vertically in a straight line. Therefore, the light shield 130 can also be raised and lowered together with the second bottom cover, and the light shield 130 can be embedded inside the cover module 110 or pulled out to the outside of the cover module 110.

[0098] 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.

[0099] 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.

[0100] In embodiments, in the display device 100 according to the present disclosure, a first drive system 150 and a second drive system 160 for raising and lowering the display panel 120 and the light shield 130, respectively, can be driven based on a first rigid chain 159 and a second rigid chain, and the occurrence of reliability degradation due to the drive belt can be prevented or reduced. It should be understood that the foregoing embodiments of the first drive system and / or the second drive system are exemplary and illustrative. The first drive system and / or the second drive system according to the exemplary embodiments of the present disclosure are not limited to a particular structure or configuration (such as the number and / or position of components). For example, the light shield 130 can be attached to the display panel 120 and, driven by the first drive system 150, embedded together with the display panel 120 into or removed from the cover module 110. Therefore, the second drive system 160 can be omitted.

[0101] For example, in the case of a belt drive system, the belt may deform due to reduced tension after prolonged use. In this case, vibration noise may occur due to belt vibration, or the display panel 120 may rise and fall unstablely.

[0102] Alternatively, raising and lowering the display panel 120 may also cause damage to the display panel 120.

[0103] 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 rigid chain 159 and a second rigid chain with semi-permanent advantages, so that deformation of the first rigid chain 159 and the second rigid chain can be prevented or mitigated even after long-term use.

[0104] Furthermore, the first drive system 150 and the second drive system 160, which include the first rigid chain 159 and the second rigid chain according to the embodiments of this disclosure, can have a very simplified structure and minimize or reduce the number of components, thereby also reducing the manufacturing cost of the display device 100.

[0105] At this time, as Figure 2C As shown, the control printed circuit board 127a, main board 127b and 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.

[0106] like Figure 2CAs shown, 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 with the first bottom cover 121.

[0107] 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 from one end of the cable penetration member 128 to the other. 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 cables to be raised and lowered without interference or damage to surrounding electronic components.

[0108] 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.

[0109] This will refer to Figure 5A and Figure 5B To describe in more detail.

[0110] Figure 5A and Figure 5B 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. For example, Figure 5A This shows the display panel being pulled down and embedded inside the cover module, and Figure 5B This shows the display panel being pulled down and removed from the outside of the cover module.

[0111] As shown in the figure (see Figure 2C , Figure 5A and Figure 5B The first rotatable bottom wheel 125 can be mounted on the first bottom cover 121 located at the lower end of the display panel 120, and the first lifting auxiliary system 180 can be disposed on the front side of the display panel 120 corresponding to the first bottom wheel 125.

[0112] The first lifting assist system 180 may include a first lifting plate 181, a first gas spring 183 provided to the first lifting plate 181, a first cable 185a and a second cable 185b connected to the first gas spring 183, and a first wheel bracket 187 and a second wheel bracket 189.

[0113] The first lifting plate 181 can be configured such that its longitudinal direction extends along the display panel 120 from... Figure 2A The cover module 110 is pulled out in the first direction. 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.

[0114] 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.

[0115] The first gas spring 183 may be equipped 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. 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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 be wound around the third round 187b and the fourth round 189b respectively.

[0120] For example, such as Figure 5A As shown, when the display panel 120 is embedded in Figure 2A 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.

[0121] Therefore, the first rod 183a of the first gas spring 183 can be embedded and disposed inside the first gas spring 183.

[0122] At this time, when the display panel 120 is moved from the first drive system 150... Figure 2A When the cover module 110 is pulled out (for example, 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 2A 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.

[0123] 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.

[0124] Therefore, it is also possible to extend from the +Y axis direction defined in the diagram. Figure 2A A force is applied to the display panel 120 as it is 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 2A It is extracted from the cover module 110.

[0125] On the contrary, such as Figure 5B As shown, when the display panel 120 is set to be pulled out... Figure 2AWhen the cover module 110 is external (e.g., when the display panel 120 is to be changed from a pull-up state to a pull-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 180, 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.

[0126] Therefore, the first rod 183a of the first gas spring 183 can extend to the outside of the first gas spring 183.

[0127] In this case, when attempting to embed the display panel 120 via the first drive system 150 Figure 2A When the cover module 110 is inside, the display panel 120 is embedded. Figure 2A 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.

[0128] 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.

[0129] Therefore, it can be embedded in the -Y axis direction defined in the figure. Figure 2A Force is applied to the display panel 120 in the cover module 110. Force can be applied to the first lifting assist system 180 and the display panel 120 in the opposite direction.

[0130] 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.

[0131] Therefore, it is possible to prevent or mitigate the impact of embedding the display panel 120 into... Figure 2A 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.

[0132] here, Figure 2A The second lifting assist system 190 may also have the same or substantially the same structure as the first lifting assist system 180, so that when... Figure 2A The second drive system 160 enables Figure 2A When the light-shielding plate 130 is raised and lowered, it causes Figure 2A The sunshade 130 from Figure 2A The speed at which the cover module 110 is raised and lowered can be controlled by Figure 2A The second lifting assist system 190 is used for control. Therefore, it can prevent or alleviate [the problem]. Figure 2A The sunshade 130 is in Figure 2A The light-shielding plate 130 is embedded in Figure 2A The cover module 110 is rapidly reduced during the internal process.

[0133] As described above, in the embodiments according to this disclosure Figure 2A The display device 100 can allow Figure 2A The display panel 120 and the light shield 130 are raised and lowered individually so as to... Figure 2A Extracted or embedded in the cover module 110 Figure 2A In the cover module 110. Therefore, by means of, including Figure 4A The first rigid chain 159 and the second rigid chain Figure 2A A simplified structure and operation, such as the first drive system 150 and the second drive system 160. Figure 2A The display panel 120 and the light shield 130 can be raised and lowered from furniture, appliances, facilities, etc. (such as headboards, tables, or partitions), thereby improving space utilization, interior design, and style.

[0134] Furthermore, the first drive system 150 and the second drive system 160, which include the first rigid chain 159 and the second rigid chain according to the embodiments of this disclosure, can have a very simplified structure and minimize or reduce the number of components, thereby also reducing the manufacturing cost of the display device 100.

[0135] 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 2A 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.

[0136] Furthermore, according to the embodiments of this disclosure Figure 2A The display device 100 may also include Figure 2A 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 2A The display panel 120 and the light shield 130 are embedded in Figure 2A The cover module 110 is rapidly reduced during the internal process.

[0137] Furthermore, as shown and described above, Figure 4B The first chain component 156 and the second chain component are respectively arranged for Figure 2A The first drive system 150 and the second drive system 160. However, Figure 4B The first chain component 156 and the second chain component can be targeted Figure 2A At least one of the first drive system 150 and the second drive system 160 is arranged in pairs.

[0138] when Figure 4B When the first chain component 156 and the second chain component are arranged in pairs, Figure 4B The first chain component 156 and the second chain component can be Figure 4A The two rigid chains 159 engage with each other during the linear movement of the two chains.

[0139] 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 any modifications and variations thereof that fall within the scope of the appended claims and their equivalents.
