Description

display device

[0001] The present invention relates to a display device capable of implementing a slim design by concealing the rear structure of a display portion.

[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] The liquid crystal panel of the liquid crystal display device includes a liquid crystal layer and a TFT substrate and a color filter substrate facing each other with the liquid crystal layer interposed therebetween, and can display an image using light provided from a backlight unit.

[0004] As an example of an electroluminescent device (ELD), an active-matrix type organic light-emitting display device is commercially available. Because OLED displays are self-luminous, they do not require a backlight and offer advantages over liquid crystal displays (LCDs) in terms of response speed, viewing angle, and other factors. Therefore, they are attracting attention as next-generation displays.

[0005] Recently, materials such as OLED can realize ultra-thin display devices because they emit light without a backlight structure on the back.

[0006] However, the overall thickness of the display device increases due to components such as the circuit board and speaker mounted on the back of the display unit. In particular, wall-mounted display devices have the problem of the rear structure of the display device being exposed due to separation from the wall.

[0007] The present invention aims to solve the above problem by providing a display device having a rear structure cover that can obtain an optical illusion effect by being integrated with a wall.

[0008] A display device is provided, comprising: a display portion; a cover bottom supporting a back surface of the display portion; an electronic component positioned on a back surface of the cover bottom; a back cover covering the electronic component; and a mirror bracket coupled to a back surface edge of the cover bottom and including a mirror surface extending obliquely from the edge of the cover bottom.

[0009] The above mirror bracket may include a first coupling surface that is in contact with the back surface of the cover bottom; and a second coupling surface that is in contact with the side surface of the back cover.

[0010] The above mirror bracket may include a magnet positioned on the second coupling surface and magnetically coupled to the back cover.

[0011] A hook groove formed on the side of the back cover and open toward the upper side; and a hook protruding from the second joining surface of the mirror bracket and vertically inserted into the hook groove may be included.

[0012] It may include a first heat dissipation hole formed on the side of the back cover; and a second heat dissipation hole formed on the second bonding surface.

[0013] The rear end of the above mirror surface and the rear end of the second bonding surface can be spaced apart.

[0014] The above mirror bracket

[0015] A first joining surface that comes into contact with the back surface of the cover bottom; and

[0016] It may include a hinge portion positioned between the mirror surface and the first coupling surface and adjusting the angle of the mirror surface.

[0017] The hinge portion may include a hinge pin penetrating an end of the mirror surface and an end of the first coupling surface; and a torsion spring wound around the hinge pin, one end of which contacts the mirror surface and the other end of which contacts the first coupling surface, to provide a force for maintaining the first angle.

[0018] An angle limiting portion may be included to limit the rotation angle of the hinge portion so that the angle between the mirror surface and the first coupling surface does not widen to a second angle or more.

[0019] The above mirror brackets can be positioned on both horizontal sides of the display device.

[0020] The thickness of the above mirror bracket may be greater than or equal to the thickness of the above back cover.

[0021] According to at least one embodiment of the present invention, an optical illusion can be achieved in which the back surface of the display device appears to be part of a wall through the mirror bracket.

[0022] Additionally, the back structure can be hidden, allowing the display device to appear thinner.

[0023] In addition, the rear hinge structure of the display device of the present invention can maintain a state of being in close contact with the wall.

[0024] Additionally, the detachable structure allows for selective application according to consumer preference.

[0025] 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.

[0041] Meanwhile, the display device (100) described herein is an intelligent display device (100) that adds computer support functions to, for example, a broadcast reception function. While remaining faithful to the broadcast reception function, it can be equipped with an Internet function and other functions, thereby providing a more convenient interface such as a manual input device, touch screen, or space remote control. In addition, it can be connected to the Internet and a computer with support for wired or wireless Internet functions, and can perform functions such as email, web browsing, banking, or games. A standardized, general-purpose operating system (OS) can be used for these various functions.

[0042] Accordingly, the display device (100) described in the present invention can perform various user-friendly functions, for example, since various applications can be freely added or deleted on a general-purpose OS kernel. More specifically, the display device (100) can be, for example, a network TV, HBB TV, smart TV, etc., and in some cases, can also be applied to a smartphone.

[0043] Figure 1 is a block diagram for explaining each configuration of a display device (100).

[0044] The display device (100) may include a communication unit (110), an input unit (120), a sensing unit (124), an output unit (150), a control unit (180), a storage unit (185), and a power supply unit (190). The configuration illustrated in FIG. 1 may include only some of the configurations, or one configuration may perform two functions.

[0045] The communication unit (110) may include a broadcast receiving unit (111) including a tuner unit and a demodulator unit. The tuner unit of the broadcast receiving unit (111) may select a broadcast signal corresponding to a channel selected by a user or all previously stored channels among broadcast signals received through an antenna or cable. The tuner unit may convert the selected broadcast signal into an intermediate frequency signal or a baseband video or audio signal.

[0046] Meanwhile, the tuner unit can sequentially select broadcast signals of all stored broadcast channels through a channel memory function among the received broadcast signals and convert them into intermediate frequency signals or baseband video or audio signals.

[0047] The demodulation unit of the broadcast receiving unit (111) can perform a demodulation operation by receiving a digital IF signal (DIF) converted by the tuner unit. The demodulation unit 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 can be input to the control unit (180). The control unit (180) can perform demultiplexing, image / audio signal processing, etc., and then output the image through the display unit (151) and output the audio through the audio output unit (152).

[0049] The external device interface unit (112) can connect an external device and a display device (100) to receive video signals, audio signals, and control signals from the external device. The interface unit (112) can be connected wired or wirelessly to external devices such as a DVD (Digital Versatile Disk), Blu-ray, game device, camera, camcorder, computer (laptop), etc.

[0050] The external device interface unit (112) transmits an image, voice, or data signal input from the outside via a connected external device to the control unit (180) of the display device (100). In addition, the image, voice, or data signal processed by the control unit (180) can be output to the connected external device.

[0051] The external device interface unit (112) may include a wired type and a wireless type. The wired type includes a physical terminal provided in the display device (100), and the wireless type may be connected to an external device through an antenna that receives a wireless signal.

[0052] The wired type may include a USB terminal, a CVBS (Composite Video Banking Sync) terminal, a component terminal, an S-video terminal (analog), a DVI (Digital Visual Interface) terminal, an HDMI (High Definition Multimedia Interface) terminal, an RGB terminal, a D-SUB terminal, etc., so as to input video and audio signals from an external device to the display device (100).

[0053] The wireless type can perform short-range wireless communication with other electronic devices located nearby. The display device (100) can be connected to a network with other electronic devices according to communication standards such as Bluetooth, RFID (Radio Frequency Identification), IrDA (Infrared Data Association), UWB (Ultra Wideband), ZigBee, and DLNA (Digital Living Network Alliance), for example.

[0054] The network interface unit (113) can access a specific web page via the connected network or another network linked to the connected network. In other words, it can access a specific web page via the network and transmit or receive data to or from the corresponding server. Additionally, it can receive content or data provided by a content provider or network operator.

[0055] That is, content such as movies, advertisements, games, VOD, and broadcast signals, as well as related information, can be received from content providers or network providers via the network. Furthermore, firmware update information and update files provided by network operators can be received. Furthermore, data can be transmitted to the Internet, content providers, or network operators.

[0056] In addition, the network interface unit (113) can select and receive a desired application from among applications open to the public through the network.

[0057] According to an embodiment, the network interface unit (113) may transmit or receive predetermined data with a user terminal connected to the display device through a network when a game application is executed on the display device. In addition, the network interface unit (113) may transmit or receive predetermined data with a server that stores game scores.

[0058] The input unit (120) may include a microphone (121) that collects sound, a user input unit (123) that detects a user's command, a sensor unit that senses the status of the display device and the surrounding conditions, and a remote signal receiving unit (125) that receives a signal from a remote control device (127).

[0059] The microphone (121) can recognize the user's voice or surrounding sounds, and in particular, receives the user's voice and processes it into electrical voice data. The microphone (121) can be implemented with various noise removal algorithms to remove noise generated during the process of receiving external audio signals.

[0060] The microphone (121) can not only collect the user's voice, convert it into voice data, and store it in the storage unit (185) or transmit it to an external device through the communication unit (110), but can also function as a user input unit (123) by analyzing the voice data and recognizing it as a user command.

[0061] The microphone (121) can be mounted on a remote control device (127) to be described later in addition to the main body of the display device (100) and transmitted to the control unit (180) through the remote signal receiving unit (125).

[0062] The user input unit (123) is a device through which a user inputs control commands to control the display device. The user input unit (123) may be configured as a keypad, button, touch pad, or touch screen.

[0063] If the user input unit (123) has a hard key button, the user can input a command related to the display device (100) by pushing the hard key button. If the user input unit (123) has a touch screen, the user can input a command related to the display device (100) using the remote control device (127) by touching the soft key of the touch screen.

[0064] In addition, the user input unit (123) may be equipped with various types of input means that can be operated by the user, such as a scroll key or a jog key, and this embodiment does not limit the scope of the present invention.

[0065] Recently, as the size of the bezel of the display device (100) has become smaller, the number of display devices (100) with a minimized user input unit (123) in the form of a physical button exposed to the outside has increased. Instead, a minimum of physical buttons are located on the back or side, and user input can be received through a remote control device (127) via a touchpad or a remote signal receiving unit (125) described later.

[0066] The remote signal receiving unit (125) can input commands related to the display device (100) through a remote control device (127) having a user input unit (123). The remote signal receiving unit (125) is a user input unit (123) and receives signals from the remote control device (127) according to various communication methods such as RF (Radio Frequency) communication method and infrared (IR) communication method, and thus may belong to a wireless communication unit.

[0067] The sensing unit (124) 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.).

[0068] Recently, display devices (100) that can move or change the direction of the display have appeared, and thus, a gyroscope sensor, an acceleration sensor, etc. may be provided to detect the attitude of the display device.

[0069] Based on the information received from the sensing unit (124), the control unit (180) can check the status of the display device (100) and, if a problem occurs, notify the user of it or control it to maintain the best status by adjusting it on its own.

[0070] In addition, the content, picture quality, size, etc. of the image provided to the display unit (151) can be controlled differently depending on the viewer detected by the sensing unit (124) or the surrounding lighting, etc., to provide an optimal viewing environment. As smart TVs advance, the functions installed in display devices are increasing, and the sensing unit (124) is also increasing along with them.

[0071] The output unit (150) is a device that provides visual and auditory information to the user through a display device, and may include a display unit (151) and an audio output unit (152).

[0072] The display unit (151) 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. The display unit (151) can include a display panel having a plurality of pixels.

[0073] The plurality of pixels provided on the display panel may have RGB sub-pixels. Alternatively, the plurality of pixels provided on the display panel may have RGBW sub-pixels. The display unit (151) may convert image signals, data signals, OSD signals, control signals, etc. processed by the control unit (180) to generate driving signals for the plurality of pixels.

[0074] The display unit (151) can be a PDP (Plasma Display Panel), LCD (Liquid Crystal Display), OLED (Organic Light Emitting Diode), a flexible display, etc., and may also be a 3D display. The 3D display unit (151) can be divided into a glasses-free type and a glasses type.

[0075] The display device (100) includes a display unit (151) that occupies most of the front surface area and a case that covers the rear side of the display unit (151) and packages the display unit (151).

[0076] Recently, display devices (100) can utilize a display unit (151) that can be bent, such as LEDs (Light Emitting Diodes) or OLEDs (Organic Light Emitting Diodes), to implement a curved screen rather than a flat screen.

[0077] Previously, LCDs were primarily used because they were unable to emit light on their own, so they relied on backlight units for light. Backlight units are devices that evenly distribute light from a light source to the liquid crystal display (LCD) located at the front. As backlight units have become thinner, thinner LCDs have become possible. However, it has been difficult to implement backlight units using flexible materials, and when the backlight unit is bent, it becomes difficult to supply light evenly to the LCD, causing screen brightness to fluctuate.

[0078] On the other hand, in the case of LEDs or OLEDs, since each element forming a pixel emits light on its own, it is possible to implement a curved display without using a backlight unit. In addition, since each element emits light on its own, even if the positional relationship with neighboring elements changes, its own brightness is not affected, so a curved display unit (150) can be implemented using LEDs or OLEDs.

[0079] OLED (Organic Light-Emitting Diodes) panels made their debut in the mid-2010s and are rapidly replacing LCDs in the small- and medium-sized display market. OLEDs utilize the self-luminous phenomenon, where fluorescent organic compounds emit light when current flows through them. Their image quality response speed is faster than that of LCDs, resulting in virtually no afterimages when displaying video.

[0080] OLED uses three types of fluorescent organic compounds with self-luminous functions: red, green, and blue. It is a luminescent display product that utilizes the phenomenon in which electrons injected from the cathode and anode and positively charged particles combine within the organic material to emit light on their own, so there is no need for a backlight (backlight device) that reduces color.

[0081] The LED (Light Emitting Diode) panel is a technology that uses one LED element as one pixel, and since the size of the LED element can be reduced compared to the past, a flexible display unit (151) can be implemented. Devices previously called LED TVs used LEDs as a light source for a backlight unit that supplied light to an LCD, and the LEDs themselves did not form a screen.

[0082] The display unit may include a plurality of pixels (R, G, B). The plurality of pixels (R, G, B) may be formed in each area where a plurality of data lines and a plurality of gate lines intersect. The plurality of pixels (R, G, B) may be arranged or arranged in a matrix form.

[0083] For example, a plurality of pixels (R, G, B) may include a red (Red, hereinafter referred to as 'R') sub-pixel, a green (Green, 'G') sub-pixel, and a blue (Blue, 'B') sub-pixel. The plurality of pixels (R, G, B) may further include a white (White, hereinafter referred to as 'W') sub-pixel.

[0084] The side of the display unit (151) that displays an image may be referred to as the front or front. When the display unit (151) displays an image, the side from which the image cannot be observed may be referred to as the rear or back. Meanwhile, the display unit (151) is configured as a touch screen and can be used as an input device in addition to an output device.

[0085] The audio output unit (152) receives a signal processed by the control unit (180) and outputs it as voice.

[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, a demodulator unit, an external device interface unit (112), or a network interface unit (113), 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 unit (151) 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 (112).

[0089] The voice signal processed by the control unit (180) can be output as audio to the audio output unit (152). In addition, the voice signal processed by the control unit (180) can be input to an external output device through the external device interface unit (112). Although not shown in FIG. 2, the control unit (180) may include a demultiplexing unit, an image processing unit, etc. This will be described later with reference to FIG. 3.

[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 (tune) 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 unit (151) to display an image. At this time, the image displayed on the display unit (151) 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 unit (151). For example, the object can be at least one of a connected web screen (newspaper, magazine, etc.), 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 unit. The camera unit can capture images of the user. The camera unit may be implemented with a single camera, but is not limited thereto, and may also be implemented with multiple cameras. Meanwhile, the camera unit may be embedded in the display device (100) above the display unit (151) or may be separately positioned. Image information captured by the camera unit may 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 unit. 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 unit (151) 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 storage unit (185) 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 (185) 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).

[0101] Programs stored in the storage unit (185) 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 (112). The storage unit (185) may store information regarding a specific broadcast channel through a channel memory function such as a channel map.

[0102] Although the storage unit (185) of FIG. 1 is illustrated as being provided separately from the control unit (180), the scope of the present invention is not limited thereto, and the storage unit (185) may be included within the control unit (180).

[0103] The storage unit (185) 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.).

[0104] 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 unit (151) for displaying images, and an audio output unit (152) for outputting audio.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] The charging cradle can be connected to the display device through an externally exposed terminal, or the built-in battery can be charged when the device is brought into proximity using a wireless method.

[0109] 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.

[0110] 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.

[0111] Figure 2 is a front perspective view illustrating an example of a display device (100).

[0112] Referring to FIG. 2, the display device (100) may have a rectangular body including a pair of long sides (LS1, LS2) and a pair of short sides (SS1, SS2). The long sides and short sides may be referred to as edges of the display device (100).

[0113] The point where the long side and the cross section meet can be called a corner (C1, C2, C3, C4).

[0114] Although the long side extending horizontally and the short side extending vertically are depicted in the drawing, the long side and the short side may be of equal length, and the long side may also be arranged vertically.

[0115] The first direction (DR1) is a direction parallel to the long side (LS1, LS2) of the display device (100), and in this embodiment is the same as the left-right direction (LR).

[0116] The second direction (DR2) may be a direction parallel to the short sides (SS1, SS2) of the display device (100) and may be a vertical direction (UD). The third direction (DR3) may be a direction perpendicular to the first direction (DR1) and / or the second direction (DR2).

[0117] For convenience of explanation, the long side is defined as the side extending in the horizontal direction (x-axis direction) and the short side is defined as the side extending in the vertical direction (y-axis direction). However, as mentioned above, the present invention is not limited thereto.

[0118] The side of the display device (100) that displays an image may be referred to as the front or front side. When the display device (100) displays an image, the side from which the image cannot be observed may be referred to as the rear or back side.

[0119] FIG. 3 is a rear perspective view of the display device (100), and FIG. 4 is a side view of the display device (100) illustrated in FIG. 3.

[0120] A cover bottom (102) having rigidity is included to cover the back surface of the display unit (151) and reinforce the rigidity of the display unit (151), and electronic components such as a circuit board and a speaker for controlling the display device (100) are mounted on the back surface of the cover bottom (102), and a back cover (104) may be further provided to cover the electronic components.

[0121] As shown in (a) of FIG. 3, the electronic components can be placed only on a part of the back surface of the display device (100) so that the back cover (104) covers only a part of the cover bottom (102), or as shown in (b) of FIG. 3, the electronic components can be placed in a distributed manner over the entire cover bottom (102) and then the back cover (104) of a size almost similar to that of the cover bottom (102) can be used to cover the electronic components.

[0122] The display device (100) illustrated in (a) of FIG. 3 may be partially thickened, but has the effect of thinning the thickness of the end portion of the display device (100), and the display device (100) illustrated in (b) of FIG. 3 has the effect of thinning the overall thickness compared to (a).

[0123] As thin-form display units (151) such as OLEDs are developed, efforts are being made to slim down the display device (100). However, there are limitations to reducing the thickness of the display device (100) due to the electronic components mounted on the rear. As shown in Fig. 4, there is a problem of a gap between the display device (100) and the wall when the display device (100) is mounted on the wall.

[0124] A design such as (a) of Fig. 3 has a thin end, so when installed on the floor, the thin design has an excellent effect, but when installed on a wall (1), the distance from the wall (1) is greater than that of the design of (b) of Fig. 3. In particular, there is a problem in that the protrusion from the wall (1) increases due to the thickness of the installation bracket (200) for installation on the wall.

[0125] Accordingly, the display device (100) of the present invention may be equipped with a mirror bracket (130) that provides an optical illusion in which the back surface of the display device (100) is perceived as part of the wall (1) to make the thickness of the display device (100) appear thinner.

[0126] FIG. 5 is a rear perspective view illustrating an example of a display device (100) of the present invention, FIG. 6 is a side view illustrating an example of a display device (100) of the present invention, and FIG. 7 is a cross-sectional view illustrating a mirror bracket (130) according to an example of a display device (100) of the present invention.

[0127] The display device (100) of the present invention further includes a mirror bracket (130) coupled to the back edge of the cover bottom (102). The size of the back cover (104) can be configured to be smaller than that of the cover bottom (102), and the mirror bracket (130) can be positioned at the edge of the cover bottom (102) exposed by the size difference between the back cover (104) and the cover bottom (102).

[0128] The mirror bracket (130) is intended to create a visual illusion, and thus may be positioned on the left and right edges of the display device (100) that are within the user's line of sight. Depending on the size or installation location of the display device (100), if the upper or lower surface of the display device (100) is exposed to the user's line of sight, it may be additionally positioned on the upper or lower edge.

[0129] The mirror bracket (130) includes a mirror surface (131) that reflects an image on the surface of the wall (1), and the mirror surface may form an inclined surface inclined toward the back from the side of the display device (100). The mirror surface (131) may be implemented with a reflective film, and the reflective film may be attached to an injection-molded product by a hot stamping method, or may be injected as an integral part with the reflective film by a double injection method.

[0130] The thickness of the mirror bracket (130) can be set so that the rear end of the mirror surface (131) touches the wall (1). Although the back cover (104) and the wall surface are shown as being attached in the drawing of Fig. 7, the mirror surface (131) can be configured to protrude further toward the rear surface of the display device (100) considering the thickness of the installation bracket (200).

[0131] The mirror bracket (130) may include a mirror surface (131) that reflects the surface of the wall (1), a first coupling surface (132) that is coupled to the back surface of the cover bottom (102), and a second coupling surface (133) that is coupled to the side surface of the back cover (104). The first coupling surface (132) and the second coupling surface (133) do not necessarily have to be fixed on both sides, and at least one side may be coupled.

[0132] The first joining surface (132) must be in close contact with the cover bottom (102) without a gap so that the front surface of the mirror surface (131) touches the cover bottom (102), but the second joining surface (133) can be fastened in a spaced-off manner. The first joining surface (132) can be fastened using an adhesive tape (139), etc.

[0133] The mirror bracket (130) is provided with a magnet (138) on the second coupling surface (133) and can be attached to the back cover (104) made of a metal material by the magnetic force of the magnet (138). The first coupling surface (132) can also be coupled to the cover bottom (102) by the magnetic force of the magnet (138).

[0134] Electronic components mounted between the back cover (104) and the cover bottom (102) may generate heat during operation. Since the rear surface of the back cover (104) is in contact with the wall (1), a first heat dissipation hole (1043) may be formed on the side surface of the back cover (104) to dissipate heat from the electronic components.

[0135] At this time, if the mirror bracket (130) is attached, the first heat dissipation hole (1043) may be blocked, so a second heat dissipation hole (not shown) is provided in the second joining surface (133) and the rear of the mirror bracket (130) is opened to discharge the heat discharged from the first heat dissipation hole (1043). As shown in Fig. 7, the mirror bracket (130) may have a structure in which the rear end of the second joining surface (133) and the rear end of the mirror surface are spaced apart from each other and the rear end is open.

[0136] Fig. 8 is a rear perspective view illustrating another example of a display device (100) of the present invention, and Fig. 9 is a perspective view illustrating a mirror bracket (130) according to another example of a display device (100) of the present invention. The mirror bracket (130) of this embodiment is characterized in that a mirror surface (131) and a first coupling surface (132) are coupled through a hinge portion, so that the angle of the mirror surface (131) is variable.

[0137] When installing a display device (100) on a wall (1), the distance from the wall (1) may vary depending on the type of installation bracket (200) or the amount of protrusion of the installation bracket (200). In addition, the rear end of the mirror bracket (130) can be maintained in close contact with the wall (1) through the hinge portion.

[0138] Referring to Fig. 9, the mirror bracket (130) of the present embodiment has an L-shape in which the first coupling surface (132) and the second coupling surface (133) are integrally formed, and the mirror bracket (130) can be connected to the end of the first coupling surface (132) via a hinge pin (134). The hinge pin (134) can penetrate the torsion spring (135) so that the rear end of the mirror surface (131) can be maintained in contact with the wall (1).

[0139] One end of the torsion spring (135) contacts the mirror surface (131) and the other end contacts the first coupling surface (132), thereby providing a force to maintain the mirror surface (131) and the first coupling surface (132) at a first angle. The first angle means an angle less than 90°, and assists in maintaining an angle at which the mirror surface (131) can reflect the surface of the wall (1).

[0140] When the display device (100) is installed on the wall (1), the mirror surface (131) is pressed against the wall (1) and the angle changes in the A direction, and the angle between the mirror surface (131) and the first coupling surface (132) may decrease. The torsion spring (135) applies force in the B direction to maintain the first angle, so that the mirror surface (131) can remain in close contact with the wall (1).

[0141] Meanwhile, when the mirror surface (131) rotates in the B direction and the mirror surface (131) and the first coupling surface (132) have an angle greater than 90°, the mirror surface (131) has an angle at which it cannot reflect the surface of the wall (1). In order to prevent this from happening, an angle limiting portion (1315, 1325) may be included to limit the mirror surface (131) and the first coupling surface (132) from being separated by more than the second angle.

[0142] The angle limiting portion may include a first edge (1315) formed on the mirror surface (131) and a second edge (1325) formed on the first coupling surface (132), as illustrated in FIG. 9. When the angle formed by the mirror surface (131) and the first coupling surface (132) is within the second angle, the first edge (1315) and the second edge (1325) are spaced apart from each other to allow rotation of the mirror surface (131), but when the second angle is reached, the first edge (1315) and the second edge (1325) come into contact, so that the angle formed by the mirror surface (131) and the first coupling surface (132) cannot increase any further. The second angle may also have a value of 90° or less.

[0143] Fig. 10 is a drawing illustrating a fastening structure of a mirror bracket (130) according to another example of a display device (100) of the present invention. The mirror bracket (130) of this embodiment can be fastened using a hook structure (1045, 136).

[0144] As shown in Fig. 8, a hook groove (1045) is formed on the side of the back cover (104), and as shown in Fig. 10(a), a hook (136) inserted into the second coupling surface (133) of the mirror bracket (130) can protrude. It can be fastened as shown in Fig. 10(b).

[0145] When the hook (136) is formed in a downward direction and the mirror bracket (130) is installed from the top to the bottom, the hook (136) does not separate from the hook groove (1045) due to the weight of the mirror bracket (130). In the case of an adhesive tape (139), separation is difficult, and in the case of a magnet (138), slipping may occur, but the hook (136) structure has a strong fixing force, so the mirror bracket (130) can be stably fastened.

[0146] Since the second bonding surface (133) is located on the inside and is not exposed to the user, even if a gap is created between the second bonding surface (133) and the back cover (104) as shown in Fig. 10(b), it does not affect the appearance of the display device (100).

[0147] According to at least one embodiment of the present invention, an optical illusion can be obtained in which the back surface of the display device (100) appears to be a part of the wall (1) through the mirror bracket (130).

[0148] Additionally, the rear structure can be hidden, so the display device (100) can appear thin.

[0149] In addition, the display device (100) of the present invention can be maintained in a state of being in close contact with the wall (1) through the rear hinge structure.

[0150] Additionally, the detachable structure allows for selective application according to consumer preference.

[0151] 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.

[0152] With respect to various embodiments for implementing the present invention, duplicate descriptions are omitted as they have been described above in the previous table of contents, Best Mode for Carrying Out the Invention.

[0153] Since the present invention can be applied to display devices in various fields, its industrial applicability is recognized.
