Description

Display device case

[0001] The present invention relates to a display device case that can stably hold a large-screen display device while protecting its appearance.

[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 displays (LCDs), field emission displays (FEDs), plasma display panels (PDPs), and electroluminescence devices.

[0003] Additionally, displays have been getting larger in recent years, and the functions of display devices have been becoming increasingly diverse.

[0004] For example, tablets can be used for data and voice communication, photography and video recording via a camera, audio recording, music playback via a speaker system, and displaying images or videos. Tablets can also be equipped with electronic game play capabilities or serve as multimedia players.

[0005] As the functions of display devices become more diverse, the time spent using the display device increases, and it becomes difficult for users to hold it in their hands for a long time, or to view images output from the display device while doing other tasks, it becomes necessary to stand the display device upright without holding it.

[0006] To this end, cases designed to hold display devices are being released. These existing cases utilize a magnetic attachment / detachment mechanism. For example, they utilize the magnetic force between a magnet located on one side of the side case and a magnet located on one side of the foldable folio cover. This allows users to easily hold display devices while enhancing portability.

[0007] However, as discussed above, displays are becoming larger, and simple magnetic attachment / detachment methods, such as those used in existing cases, have limited adhesive strength. This is because, as display devices grow larger, cases must also grow in size, increasing their weight accordingly.

[0008] Additionally, the case must be securely attached to properly support the weight of the display device. Otherwise, the case may not be able to support the weight of the display device and may be removed, potentially causing damage to the display device.

[0009] Therefore, in order to protect the appearance of a large-screen display device while at the same time stably mounting it, a means of securing the case's adhesive strength is required.

[0010] The present invention provides a display device case, and more specifically, it aims to provide a display device case capable of increasing the adhesive strength of a folio cover through a structure in which an insertion portion formed at one end of a folio cover is inserted into a fastening groove formed in a side cover.

[0011] In addition, the purpose is to provide a display device case that can increase the adhesive strength of a folio cover by minimizing the gap between magnets for fastening a folio cover and expanding the area for forming a magnetic force.

[0012] In addition, the purpose is to provide a display device case that can block foreign substances that may enter through a fastening groove after a folio cover is fastened through a fixing rib formed by protruding on the front of the rear cover.

[0013] 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.

[0014] A display device case is provided, comprising: a rear cover covering the back surface of a display module; a side cover wrapping around the side of the display module and having a fastening groove formed on one side; a folio cover having an insertion portion formed on one end thereof to be inserted into the fastening groove; and a fixing bracket coupled to one side of the side cover and having a first magnet positioned such that one side of the first magnet is in contact with one side of the inserted portion, wherein the insertion portion includes a second magnet that forms a magnetic force with the first magnet.

[0015] The above first magnet may be formed by combining multiple magnets with N and S poles arranged in an alternating manner on one surface.

[0016] The second magnet may be formed by combining multiple magnets, with the N pole and the S pole arranged in an alternating manner on one side to form a magnetic force with the N pole and the S pole of the first magnet.

[0017] The first magnet may include a marking plate coupled to one side.

[0018] The above first magnet can be arranged so that one side is perpendicular to the inner surface of the side cover.

[0019] The above rear cover may include a fixed rib that is formed to protrude from the front and comes into contact with the other surface of the inserted portion.

[0020] The above fixed rib may be formed to protrude and be inclined toward the inside from one side of the rear cover.

[0021] The above fixed ribs can be formed in multiple numbers in parallel and spaced apart from each other.

[0022] The above folio cover includes a foldable portion so that it can be folded, and when folded in a first state, the other end can be in contact with one side of the back surface of the rear cover.

[0023] The above rear cover may include a catch groove formed on the back surface into which the other end of the folio cover is inserted.

[0024] The above folio cover includes a catch formed by extending and being foldable from the other end, and the catch can be folded and inserted into the catch groove.

[0025] The above-mentioned hanging grooves can be formed in multiple numbers in parallel and spaced apart from each other.

[0026] The above folio cover can cover the front of the display module when folded in the second state.

[0027] The above folio cover includes a catch formed to be foldable and extended from the other end, and the catch can be folded and brought into contact with the other side of the side cover.

[0028] The display device case according to the present invention can increase the adhesive strength of the folio cover through a structure in which an insertion portion formed on one end of the folio cover is inserted into a fastening groove formed on a side cover.

[0029] In addition, the gap between magnets for fastening the folio cover can be minimized and the area for forming magnetic force can be expanded to increase the adhesive strength of the folio cover.

[0030] In addition, foreign substances that may enter through the fastening groove after the folio cover is fastened can be blocked through the fixed rib formed by protruding on the front of the rear cover.

[0031] The effects that can be obtained from the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by a person having ordinary skill in the art to which the present invention belongs from the description below.

[0046] 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.

[0047] 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.

[0048] Singular expressions include plural expressions unless the context clearly indicates otherwise.

[0049] 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.

[0050] Meanwhile, the display device described herein is an intelligent display device that adds computer-assisted functionality to broadcast reception, for example. While faithful to the broadcast reception function, it can also be equipped with Internet functionality and other features, providing a more user-friendly interface, such as a hand-held input device, touch screen, or space remote control. Furthermore, with support for wired or wireless Internet functionality, it can connect to the Internet and a computer, enabling functions such as email, web browsing, banking, or gaming. A standardized, general-purpose operating system can be used for these various functions.

[0051] Accordingly, the display device described in the present invention can perform a variety of user-friendly functions, for example, by allowing various applications to be freely added or deleted on a general-purpose operating system kernel. More specifically, the display device can be a network TV, HBB TV, smart TV, etc., and in some cases, it can also be applied to smartphones.

[0052] 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).

[0053] The broadcast receiving unit (110) may include a tuner unit (111) and a demodulator unit (112).

[0054] 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).

[0055] 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.

[0056] 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).

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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).

[0061] The sensing unit (120) refers to a device that detects changes within the display device (100) or detects 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.).

[0062] 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 condition by adjusting it on its own.

[0063] 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 it.

[0064] 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).

[0065] 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 located 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.

[0066] 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).

[0067] 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.

[0068] 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).

[0069] 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.).

[0070] 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).

[0071] 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.

[0072] The display device (100) may include a display module (150) that occupies most of the front surface area and a case that covers the rear side of the display module (150) and packages the display module (150).

[0073] The display module (150) may include a coupling magnet, a first power supply unit, and a first signal module.

[0074] 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.

[0075] The audio output unit (160) receives a signal processed by the control unit (180) and outputs it as voice.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] 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).

[0080] 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.

[0081] In addition, the external device interface unit (171) can establish a communication network with various remote control devices (200) to 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).

[0082] 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.

[0083] 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.

[0084] 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).

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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).

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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).

[0098] 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.

[0099] 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.

[0100] 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 audio output.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] 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).

[0106] Meanwhile, the above-described display device (100) may be a digital broadcast receiver capable of receiving fixed or mobile digital broadcasts.

[0107] 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.

[0108] 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.

In addition, the folio cover (330) may have an insertion portion (331) formed on one end thereof that is inserted into the fastening groove (321) of the side cover (320). The fixing bracket (340) may be coupled to one side of the side cover (320). In addition, the fixing bracket (340) may have a first magnet (341) positioned such that one side comes into contact with one side of the insertion portion (331) of the folio cover (330) inserted into the fastening groove (321).

[0112] In particular, a display device case (300) according to one embodiment of the present invention may have a first magnet (341) positioned on a fixing bracket (340) and a second magnet (332) forming a magnetic force positioned on an insertion portion (331) formed on a folio cover (330).

[0113] As described above, the display device case (300) according to one embodiment of the present invention aims to protect the exterior of a large-screen display device while stably holding it in place as displays become larger. This is because a simple attachment / detachment method using magnets, as in conventional cases, has limitations in adhesive strength.

[0114] Referring to FIG. 4, as the display grows larger, the size of the folio cover (330) must also increase accordingly. Consequently, the weight of the folio cover (330) inevitably increases. Consequently, sufficient adhesive strength must be secured to stably attach the folio cover (330) to the side cover (320).

[0115] Accordingly, referring to FIGS. 5 and 6 together, a display device case (300) according to one embodiment of the present invention can form a fastening groove (321) on one side of a side cover (320). In addition, an insertion portion (331) formed on one end of a folio cover (330) can be inserted into the fastening groove (321).

[0116] At this time, the first magnet (341) located in the fixed bracket (340) and the second magnet (332) located in the insertion portion (331) can form a magnetic force. In this case, the gap between the first magnet (341) and the second magnet (332) is spaced apart only by the thickness of the folio cover (330). Therefore, the gap between the first magnet (341) and the second magnet (332) can be minimized.

[0117] Ultimately, compared to the simple attachment / detachment method using magnets of a conventional case, the display device case (300) according to one embodiment of the present invention is advantageous in securing magnetic force between the first magnet (341) and the second magnet (332) because the gap between the first magnet (341) and the second magnet (332) can be minimized through the insertion structure of the folio cover (330). In addition, the attachment force of the folio cover (330) can be sufficiently secured through this.

[0118] FIG. 8 is a drawing illustrating a first magnet (341) positioned on a fixing bracket (340) in a display device case (300) according to one embodiment of the present invention. FIG. 9 is a perspective view of area B of FIG. 4. FIG. 10 is a drawing illustrating a fixing rib (311) formed on a rear cover (310) in a display device case (300) according to one embodiment of the present invention. And FIG. 11 is a drawing illustrating a state in which a folio cover (330) is folded in a second state in a display device case (300) according to one embodiment of the present invention.

[0119] According to one embodiment of the present invention, a display device case (300) may have a first magnet (341) positioned on a fixing bracket (340) coupled to one side of a side cover (320) as described above. At this time, the first magnet (341) may be positioned so that one side is perpendicular to the inner side of the side cover (320), as illustrated in FIG. 8.

[0120] This is to expand the area in which the first magnet (341) and the second magnet (332) can form a magnetic force when the insertion portion (331) of the folio cover (330) is inserted into the fastening groove (321) formed in the side cover (320).

[0121] That is, the display device case (300) according to one embodiment of the present invention can increase the adhesive strength of the folio cover (330) by minimizing the gap between the first magnet (341) and the second magnet (332) and expanding the area for forming a magnetic force. In addition, through this, the number of magnets for attaching the folio cover (330) to the side cover (320) can be minimized, thereby achieving the effect of cost reduction.

[0122] In addition, in the display device case (300) according to one embodiment of the present invention, the rear cover (310) may include a fixing rib (311) that is formed to protrude from the front and comes into contact with the other surface of the insertion portion (331) of the folio cover (330) inserted into the fastening groove (321).

[0123] Here, the display device case (300) according to one embodiment of the present invention can stably fix the insertion portion (331) of the folio cover (330) inserted into the fastening groove (321) through the fixing rib (311). In addition, it can block foreign substances that may enter through the fastening groove (321) after the folio cover (330) is inserted through the fixing rib (311).

[0124] In addition, referring to FIG. 10, in a display device case (300) according to one embodiment of the present invention, a fixed rib (311) may be formed to protrude inward from one side of the rear cover (310) and be inclined. In addition, a plurality of fixed ribs (311) may be formed in parallel and spaced apart from each other.

[0125] This is to allow the user to easily separate the folio cover (330) after the folio cover (330) is fastened. That is, a space can be formed between one side of the rear cover (310) and the insertion part (331) of the folio cover (330) through the inclined fixed rib (311), and the user can easily separate the insertion part (331) of the folio cover (330) that forms a magnetic force with the first magnet (341) through the action of pressing the insertion part (331).

[0126] Accordingly, the display device case (300) according to one embodiment of the present invention can increase the adhesive strength of the folio cover (330) by sufficiently securing the magnetic force of the first magnet (341) and the second magnet (332) through a structure in which the folio cover (330) is inserted into the side cover (320). At the same time, the user can easily separate the folio cover (330) by pressing the insertion portion (331) through the fixing rib (311) formed slantedly on the rear cover (310), thereby further increasing the convenience of use.

[0127] Referring again to FIGS. 3 and 6, in a display device case (300) according to one embodiment of the present invention, the folio cover (330) may include a foldable portion (333) to enable folding. As illustrated in FIG. 3, when the folio cover (330) is folded in a first state, the other end of the folio cover (330) may come into contact with one side of the back surface of the rear cover (310), thereby supporting the display device.

[0128] In addition, as illustrated in FIG. 3, in a display device case (300) according to one embodiment of the present invention, the rear cover (310) may be formed on the back surface and may include a catch groove (312) into which the other end of the folio cover (330) is inserted. Through this, a large-screen display device can be supported more stably.

[0129] In addition, in the display device case (300) according to one embodiment of the present invention, the folio cover (330) may include a catch portion (334) formed to be foldable and extended from the other end. Accordingly, as illustrated in FIG. 3, the catch portion (334) may be folded, and the thickness of the other end of the folio cover (330) may be increased, and the catch portion (334) may be fitted into the catch groove (312) to more stably support a large-screen display device.

[0130] In addition, as illustrated in FIG. 3, a plurality of catch grooves (312) formed on the back surface of the rear cover (310) of the display device case (300) according to one embodiment of the present invention may be formed in parallel and spaced apart from each other. Through this, the user can easily adjust the angle at which the display device is set up according to their convenience.

[0131] And referring to FIG. 3 and FIG. 11 together, in the display device case (300) according to one embodiment of the present invention, the folio cover (330) can cover the front of the display module (150) when folded in the second state. That is, the folio cover (330) supports the display device when folded in the first state, and covers the front of the display module (150) when folded in the second state, thereby protecting the appearance of the large-screen display device.

[0132] Additionally, as illustrated in FIG. 11, in a display device case (300) according to one embodiment of the present invention, the folio cover (330) may include a hook (334) that is formed to be foldable and extend from the other end. The hook (334) may be folded and come into contact with the other side of the side cover (320). This is to enhance the outer protection of the display device by coupling the hook (334) to the other side of the side cover (320) when the folio cover (330) is folded in the second state. At this time, the hook (334) and the other side of the side cover (320) may be attached through magnetic force using a magnet. In addition, they may also be coupled through a separate coupling structure, for example, a hook-using coupling structure.

[0133] Fig. 12 is a drawing illustrating another embodiment of the first magnet (341) in the display device case (300) of the present invention. And Fig. 13 is a drawing illustrating another embodiment of the second magnet (332) positioned in the insertion portion (331) of the folio cover (330) in the display device case (300) of the present invention.

[0134] As described above with reference to FIGS. 2 to 11, the display device case (300) according to one embodiment of the present invention can secure the adhesive force of the folio cover (330) through an insertion structure that allows the insertion portion (331) of the folio cover (330) to be inserted into a fastening groove (321) formed in the side cover (320), and the magnetic force between the first magnet (341) and the second magnet (332). At this time, the adhesive force of the folio cover (330) can be secured by expanding the area where the magnetic force is formed through the arrangement structure of the first magnet (341) and the second magnet (332).

[0135] In addition, the display device case (300) according to one embodiment of the present invention can arrange the N-pole magnet and the S-pole magnet in an alternating manner as shown in FIGS. 12 and 13 to secure magnetic force between the first magnet (341) and the second magnet (332).

[0136] That is, the first magnet (341) may be formed by combining multiple magnets with N poles (341a) and S poles (341b) arranged in an alternating manner on one surface. In addition, the second magnet (332) may be formed by combining multiple magnets with S poles (332a) and N poles (332b) arranged in an alternating manner on one surface to form a magnetic force with the N pole (341a) and S pole (341b) of the first magnet (341).

[0137] Accordingly, the display device case (300) according to one embodiment of the present invention has N poles (341a, 332b) and S poles (341b, 332a) arranged in an alternating manner on one surface forming the magnetic force of the first magnet (341) and the second magnet (332), thereby increasing the magnetic force formed between the first magnet (341) and the second magnet (332), thereby further improving the adhesive force of the folio cover (330).

[0138] Furthermore, the display device case (300) according to one embodiment of the present invention can reduce the repulsive force between the first magnet (341) and the second magnet (332) in which the N-pole magnet and the S-pole magnet are arranged in an alternating manner when the insertion portion (331) of the folio cover (330) is inserted into the fastening groove (321) formed in the side cover (320).

[0139] That is, when the N and S poles are arranged in an alternating manner on the surface that forms the magnetic force, the repulsive force that may occur when they come into close proximity can be reduced compared to when one N pole or one S pole is configured on the surface that forms the magnetic force. Through this, the insertion part (331) of the folio cover (330) can be inserted into the fastening groove (321) without twisting, thereby further enhancing the convenience of the user.

[0140] In addition, referring to FIGS. 7, 12 and 13 together, in a display device case (300) according to one embodiment of the present invention, the first magnet (341) may include a marking plate (342) coupled to one side. This is to increase convenience for positioning the first magnet (341), in which the N-pole magnet and the S-pole magnet are arranged crosswise and coupled, on the fixing bracket (340) when manufacturing the display device case (300) of the present invention.

[0141] This is because, if the direction in which the first magnet (341) is positioned is incorrect, it may form a repulsive force rather than a magnetic force with the second magnet (332).

[0142] Therefore, when manufacturing the display device (300) of the present invention, the first magnet (341) can be correctly positioned on the fixing bracket (340) through the marking plate (342) coupled to one side of the first magnet (341).

[0143] In addition, the display device case (300) according to one embodiment of the present invention can also combine a marking plate (342) to one side of the second magnet (332). Through this, the second magnet (332) can be positioned in the correct direction in the insertion portion (331) of the folio cover (330) during the manufacturing process, thereby forming a magnetic force with the first magnet (341) positioned in the fixing bracket (340).

[0144] In summary, the display device case according to the present invention can increase the adhesive strength of the folio cover by having a structure in which an insert formed at one end of the folio cover is inserted into a fastening groove formed in a side cover. In addition, the gap between magnets for fastening the folio cover can be minimized and the area for forming a magnetic force can be expanded to increase the adhesive strength of the folio cover. In addition, the fixing rib formed to protrude on the front of the rear cover can block foreign substances that may enter through the fastening groove after fastening the folio cover.

[0145] The above detailed description should not be construed as limiting in any respect and should be considered illustrative only. The scope of the present invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the present invention are intended to be included within the scope of the present invention.
