Description

display device

[0001] The present invention relates to a display device that can be used for various purposes other than viewing images through a rotational structure of the display.

[0002] As the information society develops, the demand for display devices is also increasing in various forms, and in response to this, recent display devices include liquid crystal display devices (LCD), field emission display devices (FED), plasma display panels (PDP), and electroluminescence devices.

[0003] In addition, displays have been becoming larger in recent years, and the importance of the external design of display devices to meet the needs of consumers is being highlighted.

[0004] Recently, modern people are spending more time using portable electronic devices like smartphones, and their busy schedules are reducing the amount of time they spend watching TV at home. Furthermore, as TVs grow larger, the amount of space required for TV installation in living spaces is inevitably increasing.

[0005] In addition, since the TV has a display unit located on the front to output images, in order for the TV to function, the display unit must be positioned according to the direction in which the user is watching, and accordingly, the direction and position of the TV are generally fixed.

[0006] Therefore, in order to increase the utilization of TV, a means is required that meets the needs of users by allowing them to use it for other purposes while not watching TV, in addition to simply watching TV.

[0007] The present invention provides a display device, and more specifically, the purpose of the present invention is to provide a display device that can be used for various purposes other than viewing images through a rotation structure of the display.

[0008] In addition, the purpose is to provide a display device that can be used even when mounted on a wall by transmitting driving force to the display to rotate in combination with linear forward and backward movement through a link module.

[0009] The problems to be solved by the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned can be clearly understood by a person having ordinary skill in the technical field to which the present invention belongs from the description below.

[0018] It may include a top frame that is connected to one end of the pair of side frames and is located on the upper side of the cover panel, and has electronic components mounted thereon that are electrically connected to the display module.

[0019] The top frame may include a first receptor positioned inside and movable in the vertical direction; a first connector coupled to the first receptor; and a third magnet arranged around the first connector.

[0020] The cover panel may include a second receptor positioned therein; a second connector coupled to the second receptor and electrically connected when in contact with the first connector; and a fourth magnet disposed around the second connector and forming a magnetic force with the third magnet.

[0021] It may include an interior member that is coupled to the back surface of the above cover panel and includes a mirror.

[0022] It may include a support frame coupled to the other end of the pair of side frames and the lower side of the cover panel.

In addition, when describing the embodiments disclosed in this specification, if it is determined that a specific description of a related known technology may obscure the gist of the embodiments disclosed in this specification, a detailed description thereof will be omitted. In addition, the attached drawings are only intended to facilitate easy understanding of the embodiments disclosed in this specification, and the technical ideas disclosed in this specification are not limited by the attached drawings, and should be understood to include all modifications, equivalents, and substitutes included in the spirit and technical scope of the present invention.

[0036] Terms that include ordinal numbers, such as first, second, etc., may be used to describe various components, but the components are not limited by these terms. These terms are used solely to distinguish one component from another.

[0037] When a component is referred to as being "connected" or "connected" to another component, it should be understood that it may be directly connected or connected to that other component, but that there may be other components intervening. Conversely, when a component is referred to as being "directly connected" or "connected" to another component, it should be understood that there are no other components intervening.

[0038] Singular expressions include plural expressions unless the context clearly indicates otherwise.

[0039] In this application, terms such as “include” or “have” are intended to specify the presence of a feature, number, step, operation, component, part or combination thereof described in the specification, but should be understood not to exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts or combinations thereof.

[0040] Figure 1 is a block diagram for explaining each component of a display device (100). The display device (100) may include a broadcast receiving unit (110), an external device interface unit (171), a network interface unit (172), a storage unit (140), a user input interface unit (173), an input unit (130), a control unit (180), a display module (150), an audio output unit (160), and / or a power supply unit (190).

[0041] The broadcast receiving unit (110) may include a tuner unit (111) and a demodulator unit (112).

[0042] Meanwhile, unlike the drawing, the display device (100) may include only the external device interface unit (171) and the network interface unit (172) among the broadcast receiving unit (110), the external device interface unit (171), and the network interface unit (172). That is, the display device (100) may not include the broadcast receiving unit (110).

[0043] The tuner unit (111) can select a broadcast signal corresponding to a channel selected by the user or all previously stored channels among broadcast signals received through an antenna (not shown) or a cable (not shown). The tuner unit (111) can convert the selected broadcast signal into an intermediate frequency signal or a baseband video or audio signal.

[0044] For example, the tuner unit (111) can convert the selected broadcast signal into a digital IF signal (DIF) if it is a digital broadcast signal, and can convert it into an analog baseband video or audio signal (CVBS / SIF) if it is an analog broadcast signal. That is, the tuner unit (111) can process a digital broadcast signal or an analog broadcast signal. The analog baseband video or audio signal (CVBS / SIF) output from the tuner unit (111) can be directly input to the control unit (180).

[0045] Meanwhile, the tuner unit (111) can sequentially select broadcast signals of all stored broadcast channels through the channel memory function among the received broadcast signals and convert them into intermediate frequency signals or baseband video or audio signals.

[0046] Meanwhile, the tuner unit (111) may be equipped with multiple tuners to receive broadcast signals of multiple channels. Alternatively, a single tuner that simultaneously receives broadcast signals of multiple channels is also possible.

[0047] The demodulation unit (112) can perform a demodulation operation by receiving a digital IF signal (DIF) converted by the tuner unit (111). The demodulation unit (112) can output a stream signal (TS) after performing demodulation and channel decoding. At this time, the stream signal can be a signal in which a video signal, an audio signal, or a data signal is multiplexed.

[0048] The stream signal output from the demodulation unit (112) can be input to the control unit (180). The control unit (180) can perform demultiplexing, image / audio signal processing, etc., and then output an image through the display module (150) and output an audio through the audio output unit (160).

[0049] The sensing unit (120) refers to a device that detects changes within the display device (100) or external changes. For example, it may include at least one of a proximity sensor, an illumination sensor, a touch sensor, an infrared sensor (IR sensor), an ultrasonic sensor, an optical sensor (e.g., a camera), a voice sensor (e.g., a microphone), a battery gauge, and an environmental sensor (e.g., a hygrometer, a thermometer, etc.).

[0050] The control unit (180) can check the status of the display device (100) based on the information collected from the sensing unit (120), and if a problem occurs, can notify the user of it or control it to maintain the best status by adjusting it on its own.

[0051] In addition, the content, picture quality, size, etc. of the image provided to the display module (150) can be controlled differently depending on the viewer detected by the sensing unit (120) or the surrounding lighting, etc., to provide an optimal viewing environment. As smart TVs advance, the functions installed in the display device (100) are increasing, and the sensing unit (120) is also increasing along with this.

[0052] The input unit (130) may be provided on one side of the main body of the display device (100). For example, the input unit (130) may include a touch pad, a physical button, etc. The input unit (130) may receive various user commands related to the operation of the display device (100) and transmit a control signal corresponding to the input command to the control unit (180).

[0053] Recently, as the size of the bezel of the display device (100) has become smaller, the number of display devices (100) with a minimal input unit (130) in the form of a physical button exposed to the outside has increased. Instead, a minimum number of physical buttons are positioned on the back or side, and user input can be received through a remote control device (200) via a touchpad or a user input interface unit (173) described later.

[0054] The storage unit (140) may store programs for each signal processing and control within the control unit (180), or may store signal-processed video, audio, or data signals. For example, the storage unit (140) may store application programs designed for the purpose of performing various tasks that can be processed by the control unit (180), and may selectively provide some of the stored application programs upon request from the control unit (180).

[0055] Programs stored in the storage unit (140) are not particularly limited as long as they can be executed by the control unit (180). The storage unit (140) may also perform a function for temporarily storing video, audio, or data signals received from an external device through the external device interface unit (171). The storage unit (140) may store information regarding a specific broadcast channel through a channel memory function such as a channel map.

[0056] Although the storage unit (140) of FIG. 1 is provided separately from the control unit (180), the scope of the present invention is not limited thereto, and the storage unit (140) may be included within the control unit (180).

[0057] The storage unit (140) may include at least one of volatile memory (e.g., DRAM, SRAM, SDRAM, etc.) or non-volatile memory (e.g., flash memory, hard disk drive (HDD), solid-state drive (SSD), etc.).

[0058] The display module (150) can generate a driving signal by converting a video signal, data signal, OSD signal, control signal, etc. processed by the control unit (180) or a video signal, data signal, control signal, etc. received from the interface unit (171).

[0059] The display module (150) can be a flexible display, and may also be a 3D display. The 3D display module (150) can be divided into a glasses-free type and a glasses type.

[0060] The display module (150) may include a coupling magnet, a first power supply unit, and a first signal module.

[0061] The side of the display module (150) that displays an image may be referred to as the front or front. When the display module (150) displays an image, the side from which the image cannot be observed may be referred to as the rear or back. Meanwhile, the display module (150) is configured as a touch screen and can be used as an input device in addition to an output device.

[0062] The audio output unit (160) receives a signal processed by the control unit (180) and outputs it as voice.

[0063] The interface unit (170) serves as a passageway for various types of external devices connected to the display device (100). The interface unit may include not only a wired method for transmitting and receiving data through a cable, but also a wireless method using an antenna.

[0064] The interface unit (170) may include at least one of a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, a port for connecting a device equipped with an identification module, an audio I / O (Input / Output) port, a video I / O (Input / Output) port, and an earphone port.

[0065] As an example of a wireless method, the broadcast receiving unit (110) described above may be included, and may include not only broadcast signals but also mobile communication signals, short-range communication signals, wireless Internet signals, etc.

[0066] The external device interface unit (171) can transmit or receive data with a connected external device. To this end, the external device interface unit (171) may include an A / V input / output unit (not shown).

[0067] The external device interface unit (171) can be connected to external devices such as a DVD (Digital Versatile Disk), Blu-ray, game device, camera, camcorder, computer (laptop), set-top box, etc., via wired / wireless connection, and can also perform input / output operations with the external devices.

[0068] In addition, the external device interface unit (171) can establish a communication network with various remote control devices (200), and receive a control signal related to the operation of the display device (100) from the remote control device (200), or transmit data related to the operation of the display device (100) to the remote control device (200).

[0069] The external device interface unit (171) may include a wireless communication unit (not shown) for short-range wireless communication with other electronic devices. Through this wireless communication unit (not shown), the external device interface unit (171) can exchange data with an adjacent mobile terminal. In particular, in mirroring mode, the external device interface unit (171) can receive device information, running application information, application images, etc. from the mobile terminal.

[0070] The network interface unit (172) may provide an interface for connecting the display device (100) to a wired / wireless network, including the Internet. For example, the network interface unit (172) may receive content or data provided by the Internet, a content provider, or a network operator via a network. Meanwhile, the network interface unit (172) may include a communication module (not shown) for connection to a wired / wireless network.

[0071] The external device interface unit (171) and / or the network interface unit (172) may include a communication module for short-range communication such as Wi-Fi (Wireless Fidelity), Bluetooth, Bluetooth Low Energy (BLE), Zigbee, and NFC (Near Field Communication), a communication module for cellular communication such as LTE (long-term evolution), LTE-A (LTE Advance), CDMA (code division multiple access), WCDMA (wideband CDMA), UMTS (universal mobile telecommunications system), and WiBro (Wireless Broadband).

[0072] The user input interface unit (173) can transmit a signal input by the user to the control unit (180), or transmit a signal from the control unit (180) to the user. For example, it can transmit / receive a user input signal such as power on / off, channel selection, screen setting, etc. from a remote control device (200), or transmit a user input signal input from a local key (not shown) such as a power key, a channel key, a volume key, a setting value, etc. to the control unit (180), or transmit a user input signal input from a sensor unit (not shown) that senses a user's gesture to the control unit (180), or transmit a signal from the control unit (180) to the sensor unit.

[0073] The control unit (180) may include at least one processor, and may control the overall operation of the display device (100) using the processor included therein. Here, the processor may be a general processor such as a central processing unit (CPU). Of course, the processor may be a dedicated device such as an ASIC or another hardware-based processor.

[0074] The control unit (180) can demultiplex a stream input through a tuner unit (111), a demodulator unit (112), an external device interface unit (171), or a network interface unit (172), or process demultiplexed signals to generate and output a signal for video or audio output.

[0075] The image signal processed by the control unit (180) can be input to the display module (150) and displayed as an image corresponding to the image signal. In addition, the image signal processed by the control unit (180) can also be input to an external output device through the external device interface unit (171).

[0076] The voice signal processed in the control unit (180) can be output as sound to the audio output unit (160). In addition, the voice signal processed in the control unit (180) can be input to an external output device through the external device interface unit (171). Although not shown in FIG. 2, the control unit (180) may include a demultiplexing unit, an image processing unit, etc.

[0077] In addition, the control unit (180) can control the overall operation within the display device (100). For example, the control unit (180) can control the tuner unit (111) to select (tuning) a broadcast corresponding to a channel selected by the user or a previously stored channel.

[0078] In addition, the control unit (180) can control the display device (100) by a user command or an internal program input through the user input interface unit (173). Meanwhile, the control unit (180) can control the display module (150) to display an image. At this time, the image displayed on the display module (150) may be a still image or a moving image, and may be a 2D image or a 3D image.

[0079] Meanwhile, the control unit (180) can cause a predetermined 2D object to be displayed within an image displayed on the display module (150). For example, the object can be at least one of a connected web screen (newspaper, magazine, etc.), an EPG (Electronic Program Guide), various menus, widgets, icons, still images, videos, and text.

[0080] Meanwhile, the control unit (180) may modulate and / or demodulate a signal using the Amplitude Shift Keying (ASK) method. Here, the Amplitude Shift Keying (ASK) method may mean a method of modulating a signal by varying the amplitude of a carrier wave according to a data value, or of restoring an analog signal to a digital data value according to the amplitude of the carrier wave.

[0081] For example, the control unit (180) can modulate a video signal using the amplitude shift keying (ASK) method and transmit it through a wireless communication module.

[0082] For example, the control unit (180) can demodulate and process an image signal received through a wireless communication module using the amplitude shift keying (ASK) method.

[0083] Through this, the display device (100) can easily transmit and receive signals with other adjacently placed video display devices without using a unique identifier such as a MAC address (Media Access Control Address) or a complex communication protocol such as TCP / IP.

[0084] Meanwhile, the display device (100) may further include a camera (not shown). The camera can capture images of the user. The camera can be implemented with a single camera, but is not limited thereto, and may also be implemented with multiple cameras. Meanwhile, the camera can be embedded in the display device (100) above the display module (150) or can be separately positioned. Image information captured by the camera can be input to the control unit (180).

[0085] The control unit (180) can recognize the user's location based on the image captured by the camera. For example, the control unit (180) can determine the distance (z-axis coordinate) between the user and the display device (100). In addition, the control unit (180) can determine the x-axis coordinate and y-axis coordinate within the display module (150) corresponding to the user's location.

[0086] The control unit (180) can detect the user's gesture based on the image captured from the camera unit, or the signal detected from the sensor unit, or a combination thereof.

[0087] The power supply unit (190) can supply power to the entire display device (100). In particular, it can supply power to a control unit (180) that can be implemented in the form of a system on chip (SOC), a display module (150) for displaying images, and an audio output unit (160) for outputting audio.

[0088] Specifically, the power supply unit (190) may be equipped with a converter (not shown) that converts AC power into DC power and a Dc / Dc converter (not shown) that converts the level of DC power.

[0089] Meanwhile, the power supply unit (190) receives power from an external source and distributes power to each component. The power supply unit (190) may utilize a method of supplying AC power by directly connecting to an external power source, or may include a power supply unit (190) that can be recharged and used, including a battery.

[0090] The former requires a wired cable connection, making movement difficult or limited. The latter offers freedom of movement, but increases weight and volume by the battery. Charging requires a direct connection to a power cable or a charging cradle (not shown) for a set period of time.

[0091] The charging cradle can be connected to the display device through an externally exposed terminal, or the built-in battery can be charged when brought into proximity using a wireless method.

[0092] The remote control device (200) can transmit user input to the user input interface unit (173). To this end, the remote control device (200) can use Bluetooth, RF (Radio Frequency) communication, infrared (Infrared Radiation) communication, UWB (Ultra-wideband), ZigBee, etc. In addition, the remote control device (200) can receive video, audio, or data signals output from the user input interface unit (173) and display or output the same as audio on the remote control device (200).

[0093] Meanwhile, the above-described display device (100) may be a digital broadcast receiver capable of receiving fixed or mobile digital broadcasts.

[0094] Meanwhile, the block diagram of the display device (100) illustrated in FIG. 1 is only a block diagram for one embodiment of the present invention, and each component of the block diagram may be integrated, added, or omitted depending on the specifications of the display device (100) actually implemented.

[0095] That is, two or more components may be combined into a single component, or a single component may be subdivided into two or more components, as needed. Furthermore, the functions performed by each block are intended to illustrate embodiments of the present invention, and their specific operations or devices do not limit the scope of the present invention.

[0096] FIG. 2 is a front view of a display device (100) according to an embodiment of the present invention. FIG. 3 is a view illustrating a shape of a cover panel (210) rotating in a display device (100) according to an embodiment of the present invention. FIGS. 4 to 6 are drawings specifically explaining a method of rotating a cover panel (210) in a display device (100) according to an embodiment of the present invention. FIG. 7 is a drawing illustrating a link module (230) in a display device (100) according to an embodiment of the present invention. And FIG. 8 is a drawing illustrating a shape of a guide member (233) in a display device (100) according to an embodiment of the present invention.

[0097] Hereinafter, in describing a display device (100) according to one embodiment of the present invention, the left-right direction will be described based on the x-axis direction, the up-down direction will be described based on the y-axis direction, and the forward and backward directions will be described based on the z-axis direction.

[0098] A display device (100) according to one embodiment of the present invention may include a display module (150), a cover panel (210), a pair of side frames (220), and a link module (230). The cover panel (210) may surround the side periphery and the back surface of the display module (150). In addition, the pair of side frames (220) may be positioned on both sides of the cover panel (210) and may include a first guide groove (221) formed in an up-down direction (y-axis direction) on one side.

[0099] In particular, in a display device (100) according to one embodiment of the present invention, the link module (230) rotates along the first guide groove (221) between the cover panel (210) and the side frame (220), and can serve to transmit driving force so that the cover panel (210) rotates forward and backward when the front of the display module (150) is pressed.

[0100] In addition, the display device (100) according to one embodiment of the present invention may include a top frame (240) coupled to one end of a pair of side frames (220) and positioned on the upper side of a cover panel (210), and having an electronic component mounted thereon that is electrically connected to a display module (150). Furthermore, the display device (100) according to one embodiment of the present invention may include a support frame (260) coupled to the other end of a pair of side frames (220) and the lower side of the cover panel (210).

[0101] Here, the display device (100) according to one embodiment of the present invention may include an interior member (250) that is coupled to the back surface of the cover panel (210) and includes a mirror.

[0102] That is, as shown in FIGS. 2 and 3, the display device (100) according to one embodiment of the present invention may have a display module (150) positioned on the front through rotation of the cover panel (210), and may also have an interior member (250) including a mirror positioned on the front.

[0103] Below, the method of rotating the cover panel (210) that surrounds the side and back surfaces of the display module (150) through the link module (230) will be described in detail.

[0104] First, as illustrated in FIGS. 4 to 6, the top frame (240) may have a width equal to the length w in the z-axis direction facing forward and rearward. This may be formed to protrude rearward and be longer than the width of the side frame (220). This is because, in the case of the display device (100) according to one embodiment of the present invention, it may be installed on a wall. That is, in order to secure installation space while maintaining a certain distance from the wall, the top frame (240) may protrude rearward.

[0105] At this time, if the cover panel (210) has a structure that simply rotates 180 degrees, one end of the cover panel (210) gets caught on the wall, making a complete rotation impossible. Therefore, the display device (100) according to one embodiment of the present invention aims to ensure that the above-described display module (150) and the interior member (250) are alternately positioned on the front even when installed on a wall through a rotation that combines forward and backward linear movement.

[0106] To this end, in the display device (100) according to one embodiment of the present invention, the link module (230) may include a first link (231) and a second link (232). Here, the first link (231) may have one end inserted into the first guide groove (221) and the other end rotatably coupled to the cover panel (210). In addition, the second link (232) may have one end rotatably coupled to the first link (231) and the other end rotatably coupled to the other end of the side frame (220).

[0107] Furthermore, in the display device (100) according to one embodiment of the present invention, the side frame (220) may include a second guide groove (222) formed spaced apart from the first guide groove (221). Here, the second guide groove (222) may include a straight portion (222a) formed in the vertical direction (y-axis direction) and a curved portion (222b) formed by bending at both ends of the straight portion (222a).

[0108] In addition, in the display device (100) according to one embodiment of the present invention, the cover panel (210) may include a third guide groove (211) formed on one side. In addition, the link module (230) may include a guide member (233) coupled to the cover panel (210) and including a protrusion (233a) that penetrates the third guide groove (211) and is inserted into the second guide groove (222). Here, the guide member (233) may include a fourth guide groove (233b) that guides movement of the protrusion (233a) and an elastic member (233c) that comes into contact with the protrusion (233a).

[0109] More specifically, in the display device (100) according to one embodiment of the present invention, when a user presses the front of the display module (150), the cover panel (210) can rotate. At this time, one end of the first link (231) of the link module (230) can move along the first guide groove (221) while being inserted into the first guide groove (221). In addition, the protrusion (233a) of the guide member (233) can move along the second guide groove (222) while being inserted into the second guide groove (222) formed in the side frame (220) by penetrating the third guide groove (211).

[0110] As described above, since the second guide groove (222) includes a straight portion (222a) and a curved portion (222b), the protrusion (233a) moves along the curved portion (222b) of the second guide groove (222), then moves along the straight portion (222a), and then moves again along the curved portion (222b). At this time, the elastic member (233c) of the guide member (233) comes into contact with the protrusion (233a) and can apply elastic force to the protrusion (233a).

[0111] In addition, since the second link (232) of the link module (230) is rotatably coupled at one end to the first link (231) and the other end is rotatably coupled to the other end of the side frame (220), it can rotate at the other end of the side frame (220) along with the movement of the first link (231) described above.

[0112] Therefore, in the display device (100) according to one embodiment of the present invention, the cover panel (210) can perform a combination of forward and backward linear movement rather than simply rotating 180 degrees.

[0113] In addition, in the display device (100) according to one embodiment of the present invention, the length formed in the vertical direction (y-axis direction) of the first guide groove (221) can be determined by considering the width (w) of the top frame (240). In addition, through this, the area in which one end of the first link (231) moves reciprocally in the vertical direction (y-axis direction) while being inserted into the first guide groove (221) can be controlled.

[0114] That is, the display device (100) according to one embodiment of the present invention can transmit driving force so that the cover panel (210) rotates forward and backward when the front of the display module (150) is pressed through a link module (230) including a first guide groove (221) and a second guide groove (222) formed in a side frame (220), a first link (231) inserted into the first guide groove (221), and a protrusion (233a) inserted into the second guide groove (222).

[0115] FIG. 9 is a drawing for explaining the rotation of the opening / closing part (224) of the side frame (220) in the AA cross-section of FIG. 2(a). FIG. 10 is a drawing for explaining the contact between the first connector (242) and the second connector (214) in the BB cross-section of FIG. 2(a).

In addition, a hinge part (225) coupled to the fixing part (223) and the opening / closing part (224) and rotating the opening / closing part (224) when the cover panel (210) moves may be included.

[0117] In addition, the cover panel (210) may include a first magnet (212) that protrudes from the side and is coupled, and the fixing part (223) may include a fixing groove (223a) in which a second magnet (223b) that forms a magnetic force with the first magnet (212) is positioned and the other side is open.

[0118] Additionally, the hinge portion (225) may include a first hinge arm (225a) that is rotatably coupled to the fixed portion (223) about a hinge axis positioned in the vertical direction (y-axis direction) and has one end in contact with the first magnet (212). In addition, the hinge portion (225) may include a second hinge arm (225b) that is rotatably coupled to the other end of the first hinge arm (225a) and coupled to the opening / closing portion (224).

[0119] That is, the display device (100) according to one embodiment of the present invention can be coupled as illustrated in (a) of FIG. 9 through the magnetic force of the first magnet (212) coupled to the cover panel (210) and the second magnet (223b) located on the side frame (220). And, as illustrated in (b) of FIG. 9, when the cover panel (210) rotates, the opening / closing part (224) of the side frame (220) rotates through the rotation of the first hinge arm (225a) and the second hinge arm (225b), thereby forming a structure in which the front of the side frame (220) opens.

[0120] In addition, the display device (100) according to one embodiment of the present invention may include a top frame (240) that is coupled to one end of a pair of side frames (220) and is positioned on the upper side of the cover panel (210), and has electronic components mounted thereon that are electrically connected to the display module (150). This is to realize slimming of the cover panel (210) that rotates together with the display module (150). Accordingly, a printed circuit board on which electronic components are mounted, and a speaker module, etc. may be placed on the top frame (240).

[0121] Here, referring to FIG. 10, the top frame (240) may include a first receptor (241) positioned inside and movable in the up-and-down direction (y-axis direction), a first connector (242) coupled to the first receptor (241), and a third magnet (243) arranged around the first connector (242). In addition, the cover panel (210) may include a second receptor (213) positioned inside, a second connector (214) coupled to the second receptor (213) and electrically connected when in contact with the first connector (242), and a fourth magnet (215) arranged around the second connector (214) and forming a magnetic force with the third magnet (243).

[0122] That is, in the display device (100) according to one embodiment of the present invention, as shown in (a) of FIG. 10, when the cover panel (210) is rotated, the first connector (242) and the second connector (214) do not come into contact, so that the display module (150) and the electronic components mounted on the top frame (240) may not be electrically connected.

[0123] And as shown in (b) of FIG. 10, when the cover panel (210) is rotated and positioned on the top frame (240), the first receiver (241) can move and the first connector (242) and the second connector (214) can come into contact, thereby implementing an electrical connection state between the display module (150) and the electronic components mounted on the top frame (240).

[0124] Additionally, in the display device (100) according to one embodiment of the present invention, the first connector (242) and the second connector (214) illustrated in FIG. 10 may include pogo pin modules. In addition, the first connector (242) and the second connector (214) may be brought into precise contact through the third magnet (243) and the fourth magnet (215), thereby enabling smooth transmission of electrical signals.

[0125] In addition, since the display device (100) according to one embodiment of the present invention is such that the first connector (242) and the second connector (214) only come into contact when the display module (150) faces the front, the second receptor (213), the second connector (214), and the fourth magnet (215) can be formed only on one side of the cover panel (210).

[0126] And, as described above, the display device (100) according to one embodiment of the present invention can alternately place the display module (150) and the interior member (250) on the front surface by rotating the cover panel (210). Through this, a display device (100) that can be utilized for various purposes in addition to viewing images through the display module (150) can be provided.

[0127] Accordingly, as illustrated in FIGS. 2 and 3, the back surface of the cover panel (210) may include an interior member (250).

In addition, the interior member (250) may include a member with an engraved pattern or a member made of fabric, so that the display device (100) of the present invention may be utilized for purposes that can provide an interior effect indoors.

[0128] Additionally, the display device (100) according to one embodiment of the present invention can be configured to rotate the cover panel (210) in a manner as illustrated in FIG. 11 by using the driving principle in which the cover panel (210) described above rotates in a combined manner of forward and backward linear movement.

[0129] In this case, by utilizing the driving principle described above with reference to FIGS. 2 to 10, the link module (230) can be positioned left-right (x-axis direction) on the upper side of the support frame (260) located on the lower side of the top frame (240) and the cover panel (210). In addition, the configurations related to the rotation of the link module (230) can also be formed left-right (x-axis direction) on the upper and lower sides of the cover panel (210) accordingly.

[0130] In summary, the display device according to the present invention can be utilized for a variety of purposes beyond viewing images, thanks to its rotating structure. Furthermore, by transmitting driving force through the link module to allow the display to rotate in a combination of forward and backward linear movements, it can be used even when mounted on a wall.
