Description

Technical Field

[0001] Embodiments of this disclosure relate to a display device. Background Technology

[0002] Typically, flat panel displays such as plasma display panels (PDP), liquid crystal display panels (LCD), and organic light-emitting diode display panels (OLED) are mainly used.

[0003] Recent organic light-emitting display panels have cathodes and anodes as transparent electrodes, and each pixel consists of an organic light-emitting diode, a pixel circuit that drives the organic light-emitting diode, a transparent part, etc. By emitting light from both sides of the display panel, it can be used as a transparent display that can display information on both sides of the display panel.

[0004] However, while this transparent display device shows information to the user, the background of the display panel is also transparent, allowing the user to see it and letting light pass through from the background to the front. Therefore, the problem is that users cannot choose a normal viewing mode, but can only choose a dual-viewing mode.

[0005] In particular, in dual-viewing mode, light passes through the front and back of the transparent display panel, thus reducing immersion and making it difficult to develop various innovative display devices that consumers require.

[0006] Therefore, research is needed to address the aforementioned issues and to provide a display device that allows users to achieve more diverse viewing modes by allowing them to change between normal viewing mode and dual-viewing mode. Summary of the Invention

[0007] Embodiments of this disclosure provide a display device in which a user can arbitrarily switch to a normal viewing mode or a dual-viewing mode.

[0008] Furthermore, embodiments of this disclosure provide a display device that can increase marketability by enhancing the overall unity and immersion of the display device when changing between a normal viewing mode and a dual-viewing mode.

Figure 16 This is a plan view illustrating the operation of a display device according to an embodiment of the present disclosure.

[0029] like Figures 1 to 16As shown, the display device according to embodiments of the present disclosure may include: a transparent display panel 101; a housing 110 including an upper frame 105 and a lower frame 120 respectively disposed at the upper and lower ends of the housing 110 to house (e.g., disposed) the transparent display panel 101, and side frames 107 connecting the two ends of the upper frame 105 and the lower frame 120; a rotatable opening / closing member 130, one end of which is rotatably connected to the upper frame 105 and the lower frame 120 of the housing 110 to open and close the rear portion of the housing 110; a driving member 140 mounted on the lower frame 120 to rotate the rotatable opening / closing member 130; and a connecting member 150 connected to one end of the rotatable opening / closing member 130. The connecting member 150 includes a connecting gear 159, which is connected to the driving member 140 to transmit the rotational force of the driving member 140.

[0030] The transparent display panel 101 in the embodiments of this disclosure can be used, regardless of whether it is a liquid crystal display panel or an organic light-emitting display panel.

[0031] That is, when the transparent display panel 101 is configured as an LCD panel, the transparent display panel may further include: a backlight unit that illuminates the LCD panel, a lower polarizer attached to the lower substrate, and an upper polarizer attached to the front surface of the upper substrate. The specific configuration of the lower substrate and the upper substrate may be formed in various ways known to those skilled in the art, such as twisted nematic (TN) mode, vertical alignment (VA) mode, in-plane conversion (IPS) mode, and edge field conversion (FFS) mode.

[0032] When the transparent display panel 101 is configured as a light-emitting display panel, the light-emitting display panel may include a lower substrate and an upper substrate. In the lower substrate, a plurality of light-emitting units are formed in various regions defined by gate lines, data lines, and power (VDD) lines. The upper substrate is bonded to the lower substrate face-to-face. This configuration is well known in the art related to this disclosure, therefore, related drawings and detailed descriptions are not provided herein.

[0033] Thus, in embodiments of this disclosure, the transparent display panel 101 can be used regardless of its type. Therefore, the following description is given regardless of the type of display panel.

[0034] The housing 110 housing the transparent display panel 101 includes an upper frame 105 and a lower frame 120 respectively disposed on the upper and lower sides of the housing 110, and a side frame 107 connecting the two ends of the upper frame 105 and the lower frame 120, as described above. In addition, a front cover 103 surrounding the edge of the transparent display panel 101 is attached to the front surface of the housing 110.

[0035] Here, the lower frame 120 located at the lower end of the housing 110 includes an upper horizontal frame 120b and a lower horizontal frame 120a facing each other, and the drive member 140, which will be described later, is mounted between the upper horizontal frame 120b and the lower horizontal frame 120a. The rear cover 109 is attached to the rear side of the lower frame 120.

[0036] In addition, rotating opening / closing members 130 are provided in the upper frame 105 and the lower frame 120 to open and close the rear of the housing 110 according to the user's display purpose.

[0037] The rotary open / close member 130 has a first end and a second end opposite to the first end, and is rotatably coupled to the upper frame 105 and the lower frame 120, respectively. The rotary open / close member 130 is rotated by a drive member 140 mounted on the lower frame 120. In one embodiment, the rotary open / close member 130 can rotate between a first orientation and a second orientation.

[0038] Therefore, depending on whether the rotating open / close member 130 is rotated to the open or closed position, the user can use both a normal viewing mode (e.g., the first mode) and a two-sided viewing mode (e.g., the second mode). In one embodiment, in the normal viewing mode, the rotating open / close member 130 is in a first orientation with the rear surface of the housing 110 closed, such that the transparent display panel 101 can be viewed from the front surface of the housing 110 instead of the rear surface; and in the two-sided viewing mode, the rotating open / close member 130 is in a second orientation with the rear surface of the housing 110 open, such that the transparent display panel 101 can be viewed from both the front and rear surfaces of the housing 110.

[0039] Therefore, normal viewing mode refers to viewing one side of the display panel (e.g., the front) and not the other side (e.g., the rear) (such as watching TV), while dual-viewing mode refers to viewing both the front and rear sides of the display panel.

[0040] The connecting member 150, which is connected to one end of the rotary opening / closing member 130, is provided with a connecting gear 159 that is connected to the driving member 140, so that when the driving member 140 rotates, the rotational force of the driving member 140 is transmitted to the rotary opening / closing member 130.

[0041] The drive member 140 includes a drive motor 141 connected to the lower horizontal frame 120a, a first gear 142 connected to the drive motor 141 for rotation, and a sliding member 145 that slides when the drive motor 141 rotates. A second gear 143 is provided on the upper surface of the sliding member 145, which is parallel to the lower horizontal frame 120a and connected to the first gear 142. A third gear 145a is provided on the side surface of the sliding member 145, which is connected to the connecting gear 159 of the rotary opening / closing member 130.

[0042] The drive motor 141 is connected to the lower horizontal frame 120a via a motor bracket 146, and the motor bracket 146 is provided with a motor connecting part 146b, to which the drive motor 141 is connected. The motor bracket 146 is provided with a frame connecting part 146a, which protrudes from the lower side of the motor connecting part 146b, connects to the lower horizontal frame 120a, and is fixed with fasteners.

[0043] Therefore, when the first gear 142 rotates in one direction according to the rotation direction of the drive motor 141, the second gear 143, which is provided with the second gear teeth 143a meshing with the first gear teeth 142a, slides together with the sliding member 145 in one direction along the lower horizontal frame 120a.

[0044] As an example, the first gear 142 and the third gear 145a are pinions and the second gear 143 is a rack and pinion drive. The second gear 143 can be disposed separately on the upper surface of the sliding member 145 or can be integrally formed.

[0045] Then, as the sliding member 145 slides, the third gear 145a rotates the connecting gear 159 to rotate the rotation opening / closing member 130.

[0046] The connecting member 150 for transmitting the rotational force of the drive member 140 to the rotary opening / closing member 130 includes a connecting portion 151 connected to one end (e.g., the second end) of the rotary opening / closing member 130, a first support portion 153 connected to the connecting portion 151 and rotatably supported by the upper horizontal frame 120b, a main body portion 155 connected at one end to the first support portion 153 and connected to the connecting gear 159, and a second support portion 157 connected to the other end of the main body portion 155 and rotatably supported by the lower horizontal frame 120a.

[0047] The connecting portion 151 is provided with either a connecting protrusion 152b or a connecting hole 151a, and the connecting groove 152 of the rotary open / close member 130 is provided with the other of a connecting protrusion and a connecting hole at the portion that contacts the connecting portion 151. Therefore, the connecting protrusion and the connecting hole engage and connect with each other.

[0048] That is, the rotary opening / closing member 130 is formed by a pair of blades 130a and 130b combined with each other. A connecting groove 152 is formed at one end of the rotary opening / closing member 130, and the connecting portion 151 connected to the connecting groove 152 is formed in a plate shape to be inserted into the connecting groove 152, such that the connecting protrusion 152b and the connecting hole 151a engage with each other. In this embodiment, the connecting hole 151a is provided in the connecting portion 151 and the connecting protrusion 152b is provided in the connecting groove 152 as an example.

[0049] Therefore, the joint strength of the connection is increased without increasing the thickness of the rotary opening / closing member 130, so that no deformation or damage occurs when the rotational force of the drive member 140 is transmitted, and the durability is improved.

[0050] The upper horizontal frame 120b and lower horizontal frame 120a connected by the connecting member 150 are provided with rotating support holes 127 and 124, and the first support part 153 and the second support part 157 are connected to the rotating support holes 127 and 124. Rotating support members 153b and 157b supported by the rotating support holes 127 and 124 are provided on the outer peripheral surfaces of the first support part 153 and the second support part 157.

[0051] Therefore, when the rotational force of the drive member 140 is transmitted to the rotary opening / closing member 130, noise and vibration are reduced, and power can be accurately transmitted to the rotary opening / closing member 130 without loss of power.

[0052] The main body 155 of the connecting member 150 has connecting holes 155a at both ends along the longitudinal direction, and is configured such that the first support portion 153 and the second support portion 157 are respectively connected to each other. Therefore, it facilitates the assembly of the connecting member 150 and the rotary opening / closing member 130, and accurately maintains the central axis of the first support portion 153 and the second support portion 157.

[0053] The upper horizontal frame 120b and the lower horizontal frame 120s each include a first frame 120b-1 and 120a-1, which are connected to the housing 110 and have openings 125 at one end spaced apart from each other in two directions, and a second frame 120b-2 and 120a-2, which are rotatably connected to the first frame 120b-1 and 120a-1 and are connected to the first frame 120b-1 and 120a-1 by a connecting member 150.

[0054] The opening 125 is formed such that one end of the first frame 120b-1 and 120a-1 is opened, so that the second frame 120b-2 and 120a-2 can be inserted therein, and step portions 123 with upper and lower steps are provided on both sides of the opening 125.

[0055] The second frames 120b-2 and 120a-2 are provided with an insertion portion 128 and an extension portion 126 that are inserted into the opening 125. The extension portion 126 extends to both sides of the insertion portion 128 and is supported by and connected to the step portion 123. Therefore, when the insertion portion 128 of the second frames 120b-2 and 120a-2 is inserted into the opening 125 of the first frame, the extension portion 126 sits on the upper surface of the step portion 123 and is connected by fasteners.

[0056] Therefore, the second frames 120b-2 and 120a-2, in which the first support portion 153 and the second support portion 157 of the connecting member 150 are connected to the rotating support holes 127 and 124, can be slidably inserted into the first frames 120b-1 and 120a-1, and can be assembled.

[0057] In addition, the upper horizontal frame 120b and the lower horizontal frame also include column members 121, the two ends of which are connected to opposite positions of the first frames 120b-1 and 120a-1 to vertically support the upper horizontal frame 120b and the lower horizontal frame 120a.

[0058] The column member 121 is vertically mounted on the first frames 120b-1 and 120a-1 and is fixed with fasteners. Therefore, the rigidity of the upper horizontal frame 120b and the lower horizontal frame 120a is increased.

[0059] In addition, the drive member 140 may also include sensor components 161 and 163. Sensor components 161 and 163 include a first sensor 161 and a second sensor 163. The first sensor 161 is connected to the lower horizontal frame 120a to sense the sliding position of the sliding member 145, and the second sensor 163 is disposed on the sliding member 145 and adjacent to the first sensor 161.

[0060] Here, multiple first sensors 161 and second sensors 163 are provided, and the spacing between the first sensors 161 is wider than the spacing between the second sensors 163.

[0061] Therefore, as Figure 5 As shown, based on the position of any of the second sensors 163 in contact with the first sensor 161 (in this case, the rotating open / close member is perpendicular to the transparent display panel), when the sliding member slides to the right in the figure, the second sensor 163 in contact with the first sensor 161 separates from the first sensor 161 to the right. Furthermore, when the second sensor 163 adjacent to the right side contacts the sequentially arranged first sensors 161 (in this case, the rotating open / close member is parallel to the transparent display panel), the position of the sliding member is sensed.

[0062] On the other hand, the drive component 140 may also include a controller 148 for controlling the operation of the drive motor 141. The controller 148 is electrically connected to the drive motor 141 and compares signal values ​​received from the remote control 271 or the on / off switch 273 with signal values ​​received from the first sensor 161 to control whether the drive motor 141 operates and its rotation direction, thereby controlling the opening and closing of the rotary on / off component 130. The controller 148 may be implemented as an ECU or an MCU, or as a printed circuit board on which an ECU or MCU is mounted.

[0063] Here, the remote control is also electrically connected to a control board (not shown), which is electrically connected to the transparent display panel to control the image reproduction on the screen, and the on / off switch can be provided as a separate switch type in the housing. Since this technology is commonly used in the technical fields involved in this embodiment, its detailed description will be omitted.

[0064] Therefore, the first gear 142, the second gear 143 and the third gear 145a are operated by the drive motor 141, and the rotation angle of the rotary opening / closing member 130 can be controlled by sending the sliding position of the sliding member 145 to the controller 148.

[0065] The third gear 145a disposed on the side of the sliding member 145 may include a plurality of gear portions on the side surface of the sliding member 145, and these gear portions are spaced apart from each other on the side surface of the sliding member 145. In one embodiment, a second sensor 163 is disposed between a pair of gear portions of the third gear 145a. Therefore, when the sliding member 145 slides, the second sensor 163 does not interfere with the connecting gear 159.

[0066] The second sensor 163 is connected to the connecting groove 148 provided in the sliding member 145 by a fastening member, and an extension 163a extending in the direction of the first sensor 161 is provided at one end of the second sensor 163.

[0067] Therefore, when the sliding member 145 slides, the extension 163a of the second sensor 163 can move to the position closest to the first sensor 161 according to the sliding position, so that the sensing of the sliding position becomes more accurate and no errors occur.

[0068] In addition, the drive member 140 also includes: a first fixing member 181, which is connected to the sliding member 145 and slides together with the sliding member 145; a second fixing member 183, which is connected to the vertical frame 120c disposed perpendicular to the lower horizontal frame 120a and disposed along the two directions of the first fixing member 181; and an elastic member 165, which is disposed between the first fixing member 181 and the second fixing member 183 to elastically support the first fixing member 181 and the second fixing member 183 in the two directions.

[0069] That is, the first fixing member 181 is fixed to the upper surface of the sliding member 145, the second fixing member 183 is fixed to the vertical frame 120c, and the elastic member 165 is elastically supported between them.

[0070] Therefore, when the sliding member 145 slides, the first gear 142, the second gear 143, and the third gear 145a reduce the gap between the gear teeth, thereby accurately realizing the sliding position of the sliding member 145.

[0071] The first fixing member 181, the second fixing member 183, and the elastic member 165 may be provided in two or more pairs, forming a pair at the same time.

[0072] Furthermore, the lower horizontal frame 120a is provided with a guide rail 171 for guiding the sliding member 145 to slide, and the sliding member 145 has a guide member 173 that moves along the guide rail 171. Therefore, separation of the sliding member is prevented when the sliding member 145 slides.

[0073] In addition, such as Figure 9 As shown, embodiments of this disclosure may also include an upper connecting member 250 connected to the other end of the rotary opening / closing member 130.

[0074] The upper connecting member 250 includes: an upper connecting portion 251 connected to the other end of the rotatable opening / closing member 130; an upper support portion 253 connected to the upper connecting portion 251 and rotatably supported by the upper frame 105; and an upper connecting gear 279 connected to the upper support portion 253.

[0075] Here, the upper connecting portion 251 is provided with either a connecting protrusion or a connecting hole, and the other connecting protrusion or connecting hole is provided in a connecting groove at the other end of the portion of the rotary opening / closing member 130 that contacts the upper connecting portion 251 for engagement, and engages with each other.

[0076] A connecting groove 152, into which the upper connecting portion 251 is inserted, is formed at the other end of the rotary opening / closing member 130, which is formed as a pair of 130a and 130b combined with each other. The upper connecting portion 251 is formed in the shape of a plate inserted into the connecting groove 152, such that the connecting protrusion 152b and the connecting hole 251a engage with each other. In this embodiment, the connecting hole 251a is provided in the upper connecting portion 251 and the connecting protrusion 152b is provided in the connecting groove 152 as an example.

[0077] In addition, such as Figure 10 As shown, the display device also includes an upper sliding member 175, which is disposed on the upper frame 105 and connected to the upper connecting gear 179, so as to slide and move when the rotary open / close member 130 rotates.

[0078] Here, a side gear 175a that meshes with the upper connecting gear 179 is formed on the side surface of the upper sliding member 175.

[0079] The upper frame 105 is provided with a guide rail 171 for guiding the sliding of the upper sliding member 175, and the upper sliding member 175 has a guide member 173 that moves along the guide rail 171, thereby preventing the upper sliding member 175 from separating when it slides.

[0080] Therefore, when the upper connecting gear 179 rotates while the rotary opening / closing member 130 rotates, the upper sliding member 175 slides in both directions, and the rotational forces applied to one end and the other end of the rotary opening / closing member 130 (i.e., the rotational forces applied to the upper and lower parts of the rotary opening / closing member 130) are balanced, thereby precisely rotating the rotary opening / closing member 130.

[0081] In addition, the outer peripheral surface of the upper support 253 may be provided with a rotating support member 276 supported by the support hole 105a of the upper frame 105.

[0082] Furthermore, an upper rotation support member 278 is provided at the end of the upper cover 106 fixed to the housing 110 and supports the rotation of the upper support 253.

[0083] The upper rotating support member 278 is formed of an elastic material and is elastically supported between the upper cover 106 and the upper connecting member 250, so that the upper connecting member 250 rotates without deviating to either side.

[0084] Furthermore, embodiments of this disclosure may also include a lower housing 210 disposed below the housing 110, such as... Figures 13 to 15As shown. The lower housing 210 is provided with a lower opening / closing member 230 for opening and closing the rear of the lower housing 210, and the lower opening / closing member 230 is rotatably connected to the lower housing frame 220. One end and the other end of the lower housing frame 220 face each other with the lower horizontal frame 120a, and the lower opening / closing member 230 rotates together with the rotating opening / closing member 130 via the driving member 140.

[0085] The lower housing 210 may include a lower horizontal frame 120a, lower housing frames 220 facing each other, and a side extension frame 207 connected to the side frame 107.

[0086] One end of the lower opening / closing member 230, used for opening and closing the rear of the lower housing 210, is connected to the second support portion 157 of the connecting member 150, and the other end of the lower opening / closing member 230 is connected to the housing frame connecting portion 260. The lower opening / closing member 230 is rotatably connected to the lower housing frame 220. Therefore, the lower opening / closing member 230 rotates together with the rotating opening / closing member 130 by the rotational force of the driving member 140.

[0087] In this configuration, the lower connecting portion 250 is formed on the lower side of the second support portion 157, and either the connecting protrusion 231b or the connecting hole 250a is provided in the lower connecting portion 250. The lower opening / closing member 230 has another of the connecting protrusion 231b and the connecting hole 250a at the portion that contacts the lower connecting portion 250, allowing them to engage with each other. Since this is the same shape as the connecting portion described above, further description will be omitted.

[0088] In embodiments of this disclosure, as an example, a connecting hole 250a is provided in the lower connecting portion 250 and a connecting protrusion 231b is provided in the lower opening / closing member 230.

[0089] Furthermore, the housing frame connecting portion 260 is connected to the other end of the lower opening / closing member 230, and a rotating support member 267b is disposed on the outer peripheral surface of the frame support portion 267 connected to the housing frame connecting portion 260. The rotating support member 267b is connected to and rotatably supported by the lower housing frame 220.

[0090] In this way, the lower housing 210 is located at the lower part of the housing 110, and the lower opening / closing member 230 for opening and closing its rear part rotates together with the rotating opening / closing member 130, thereby increasing the sense of unity and immersion of the entire display device when the user changes the normal viewing mode or the dual-viewing mode, thus increasing commercial value.

[0091] Furthermore, if images such as landscapes, people, or photos are provided on the rear surfaces of the rotating open / close member 130 and the lower open / close member 230, the housing 110 and the lower housing 210 can perform a frame function when the user closes the display panel 101, allowing the user to use all of the normal viewing mode, double-sided viewing mode, and frame mode.

[0092] In addition, such as Figure 16 As shown, the overlapping member 290 can be disposed on one front side and the other rear side of the rotating open / close member 130 and the lower open / close member 230. Therefore, when the rotating open / close member 130 and the lower open / close member 230 are rotated, they can completely block light passing through the transparent display panel 101.

[0093] Therefore, when the rotating open / close member 130 and the lower open / close member 230 are arranged in parallel, the overlapping member 290 overlaps with the adjacent rotating open / close member 130 or lower open / close member 230, and can completely block the light transmitted to the transparent display panel 101.

[0094] As described above, according to embodiments of the present disclosure, a display device can be provided in which a user can arbitrarily switch to a normal viewing mode or a dual-viewing mode.

[0095] Furthermore, according to embodiments of this disclosure, a display device can be provided that, when changing from a normal viewing mode to a dual-viewing mode in the display device, can increase marketability by enhancing the sense of unity and immersion of the entire display device.

[0096] The above description is provided to enable those skilled in the art to implement and use the technical ideas of the present invention, and is given in the context of a particular application and its requirements. Various modifications, additions, and substitutions to the described embodiments will be apparent to those skilled in the art, and the general principles defined herein can be applied to other embodiments and applications without departing from the spirit and scope of the invention. The above description and drawings provide examples of the technical ideas of the invention for illustrative purposes only. That is, the disclosed embodiments are intended to illustrate the scope of the technical ideas of the invention.
