[0031] Hereinafter, embodiments of the present disclosure will be described in more detail with reference to the attached drawings.

[0032] FIG. 1 is a drawing for explaining a display device and a switchable mirror according to an embodiment of the present disclosure.

[0033] According to an embodiment of the present disclosure, a switchable mirror (200) may be attached to a display device (100).

[0034] When a switchable mirror (200) is attached to a display device (100) according to an embodiment, the display device can operate as various types of mirror display devices capable of transmitting information while providing a mirror function.

[0035] Here, Mirror Display is a compound word of 'Mirror', meaning mirror, and 'Display', meaning the work of visually expressing information.

[0036] According to an embodiment, the display device (100) may be implemented as a TV, but is not limited thereto. For example, the display device (100) may be applied to any device with a display function, such as a video wall, a large format display (LFD), a digital signage, a digital information display (DID), a projector display, etc., without limitation.

[0037] Depending on the embodiment, the switchable mirror (200) may be implemented in various forms that can be attached to the display device (100). For example, the switchable mirror (200) may be implemented in a hook or hook shape that can be hung on the display device (100), as illustrated in FIG. 1.

[0038] However, this is an example for convenience of explanation and is not limited thereto. For example, the switchable mirror (200) may be attached to the display device (100) by magnetism, and the switchable mirror (200) may be attached to the display device (100) through a connecting ring (or clip, screw, bolt, etc.) provided on each of the switchable mirror (200) and the display device (100).

[0039] FIG. 2 is a drawing for explaining a display device with a switchable mirror attached according to an embodiment of the present disclosure.

[0040] Referring to FIG. 2, the switchable mirror (200) may include a mirror layer.

[0041] According to an embodiment, a display panel included in a display device (100) may provide a display function.

[0042] According to an embodiment, the display panel may include a display including a self-luminous element, or may include a non-luminous element and a backlight. For example, the display panel may be implemented as various types of displays such as an LCD (Liquid Crystal Display), an OLED (Organic Light Emitting Diodes) display, an LED (Light Emitting Diodes), a micro LED, a Mini LED, a PDP (Plasma Display Panel), a QD (Quantum dot) display, a QLED (Quantum dot light-emitting diodes), etc.

[0043] For example, the switchable mirror (200) may be positioned on the front side of a display panel provided in the display device (100) when the switchable mirror (200) is attached to the display device (100) and may include a mirror layer whose reflectivity can be controlled (or adjusted). For example, when the switchable mirror (200) is attached to the display device (100), the mirror layer may be positioned adjacent to the front side of the display panel.

[0044] According to an embodiment, the mirror layer included in the switchable mirror (200) may be implemented as a glass plate or a transparent plastic plate on which a metal thin film or a dielectric multilayer film is deposited that reflects a portion of the incident light and transmits the other portion, thereby providing a mirror function.

[0045] For example, if the reflectivity of the mirror layer is the maximum reflectivity, the mirror layer reflects all of the incident light and does not transmit the content displayed by the display panel of the display device (100), so that some areas overlapping the switchable mirror among the entire area of ​​the display panel (or some areas covered by the switchable mirror) only provide a mirror function and cannot provide a display function.

[0046] For example, if the reflectivity of the mirror layer is the minimum reflectivity, the mirror layer transmits all of the incident light and transmits the content displayed by the display panel of the display device (100), so some areas of the display panel cannot provide the mirror function and can only provide the display function.

[0047] For example, if the reflectivity of the mirror layer is between the minimum reflectivity and the maximum reflectivity, the mirror layer reflects a portion of the incident light and transmits the content displayed by the display panel of the display device (100), so that some areas of the display panel can provide both a mirror function and a display function.

[0048] According to an embodiment, the switchable mirror (200) can operate as an independent device providing a mirror function when detached from the display device (100).

[0049] FIG. 3 is a block diagram showing the configuration of a display device according to an embodiment of the present disclosure.

[0050] Referring to FIG. 3, the display device (100) includes a display panel (110), a memory (120), a communication interface (130), a wireless power transmitter (140), and one or more processors (150). Duplicate descriptions will be omitted.

[0051] A memory (120) according to an embodiment of the present disclosure can store data required for various embodiments of the present disclosure.

[0052] The memory (120) may be implemented in the form of memory embedded in the display device (100) or may be implemented in the form of memory that can be attached or detached from the display device (100) depending on the purpose of data storage. For example, data for driving the display device (100) may be stored in a memory embedded in the display device (100), and data for the expansion function of the display device (100) may be stored in a memory that can be attached or detached from the display device (100). Meanwhile, in the case of memory embedded in the display device (100), it may be implemented as at least one of volatile memory (e.g., dynamic RAM (DRAM), static RAM (SRAM), or synchronous dynamic RAM (SDRAM)), non-volatile memory (e.g., one time programmable ROM (OTPROM), programmable ROM (PROM), erasable and programmable ROM (EPROM), electrically erasable and programmable ROM (EEPROM), mask ROM, flash ROM, flash memory (e.g., NAND flash or NOR flash), hard drive, or solid state drive (SSD)). In addition, in the case of memory that can be detachably attached to the display device (100), it may be implemented as at least one of memory cards (e.g., compact flash (CF), secure digital (SD), micro secure digital (Micro-SD), mini secure digital (Mini-SD), extreme digital (xD), multi-media card (MMC), etc.), external memory that can be connected to a USB port (e.g., USB memory), etc. It can be implemented.

[0053] According to an embodiment, the memory (120) may store a computer program including at least one instruction or instructions for controlling the display device (100).

[0054] According to an embodiment, the memory (120) may store content received from an external device (e.g., a source device), an external storage medium (e.g., USB), an external server (e.g., web hard), etc. Alternatively, the memory (120) may store an image received from the switchable mirror (200) when the image is acquired through a camera provided in the switchable mirror (200).

[0055] According to an embodiment, the memory (120) may store various information required for image quality processing, for example, information for performing at least one of Noise Reduction, Detail Enhancement, Tone Mapping, Contrast Enhancement, Color Enhancement, or Frame Rate Conversion, an algorithm (e.g., a neural network model), image quality parameters, etc.

[0056] According to an embodiment of the present disclosure, the memory (120) can store various information, algorithms (e.g., neural network models), size (or resolution) parameters, etc. required for content conversion (e.g., resizing of content, adjusting the resolution of content (e.g., up scaling, down scaling, etc.)).

[0057] According to an embodiment, the memory (120) may be implemented as a single memory that stores data generated from various operations according to the present disclosure. However, according to another embodiment, the memory may be implemented to include multiple memories that each store different types of data or each store data generated at different stages.

[0058] In addition, the memory (120) can store various data, programs, or applications for driving / controlling the display device (100). In addition, the memory (120) can include a user sensing module, a communication control module, a voice recognition module, a motion recognition module, a light receiving module, a display control module, an audio control module, an external input control module, a power control module, a voice database (DB), or a motion database (DB).

[0059] In the above-described embodiment, it has been described that various data are stored in the external memory of one or more processors (150), but it is of course possible that at least some of the above-described data may be stored in the internal memory of one or more processors (150).

[0060] The communication interface (130) may include a wired or wireless input / output interface (or input / output terminal) according to various standards.

[0061] For example, the communication interface (130) may include various communication interfaces such as wired-based HDMI (High Definition Multimedia Interface), MHL (Mobile High-Definition Link), USB (Universal Serial Bus), DP (Display Port), Thunderbolt, VGA (Video Graphics Array) port, RGB port, D-SUB (D-subminiature), DVI (Digital Visual Interface), etc.

[0062] Not limited thereto, the communication interface (130) may include various interfaces such as AP-based Wi-Fi (Wireless LAN network), Bluetooth, Zigbee, wired / wireless LAN (Local Area Network), WAN (Wide Area Network), Ethernet, WFD (Wi-Fi Direct), infrared communication (IrDA, infrared Data Association), BLE (Bluetooth Low Energy), NFC (Near Field Communication), Wibro (Wireless Broadband Internet, Wibro), WiMAX (World Interoperability for Microwave Access, WiMAX), SWAP (Shared Wireless Access Protocol), WiGig (Wireless Gigabit Alliances, WiGig), RF communication, RFID (Radio-Frequency Identification), IEEE 1394, AES / EBU (Audio Engineering Society / European Broadcasting Union), optical, and coaxial.

[0063] According to an embodiment, the communication interface (130) can communicate with a switchable mirror (200) attached to the display device (100), and of course, can also communicate with various types of external devices that provide content.

[0064] For example, the communication interface (130) may be attached to the display device (100) so that the switchable mirror (200) can communicate with the switchable mirror (200) through a connection between a port (e.g., a wired connection port of various types) included in the communication interface (130) and a port provided in the switchable mirror (200).

[0065] However, the present invention is not limited thereto, and the communication interface (130) may of course communicate wirelessly with the switchable mirror (200). For example, the display device (100) may communicate with the switchable mirror (200) according to various types of wireless communication standards, such as Wi-Fi, Bluetooth, WFD (Wi-Fi Direct), infrared communication (IrDA, infrared Data Association), BLE (Bluetooth Low Energy), NFC (Near Field Communication), Wibro (Wireless Broadband Internet, Wibro), WiMAX (World Interoperability for Microwave Access, WiMAX), SWAP (Shared Wireless Access Protocol), WiGig (Wireless Gigabit Alliances, WiGig), RF communication, and RFID (Radio-Frequency Identification).

[0066] In addition, as described below, when the attachment of the switchable mirror (200) is identified through multiple sensors, a control signal for controlling the reflectivity can be transmitted through communication according to various types of wired / wireless standards, or an image acquired through a camera equipped in the switchable mirror (200) can be received.

[0067] For example, when one or more processors (150) communicate wirelessly with a switchable mirror (200), synchronization is not performed until the attachment of the switchable mirror (200) is identified, and when the attachment of the switchable mirror (200) is identified, synchronization is performed through wireless communication to transmit a control signal to the switchable mirror (200) or receive an image from the switchable mirror (200).

[0068] According to an embodiment, the display device (100) may include a wireless power transmitter (140) that transmits wireless power. According to an embodiment, the wireless power transmitter (140) may include an EMI filter, a PFC circuit, an inverter, a transmission coil, and the like.

[0069] An EMI filter rectifies and smooths the input commercial power, outputting a DC voltage of a certain level. A half-wave or full-wave rectifier circuit can be used for rectification, and a capacitor can be connected in parallel with the output of the rectifier circuit for smoothing.

[0070] The Power Factor Correction (PFC) circuit can reduce the phase difference between the DC voltage and DC current input through the EMI filter. This offsets reactive power, thereby increasing power efficiency. The inverter converts the DC current output from the PFC circuit, which is power factor compensated, back into AC current for use by the transmitter coil (Tx coil). Consequently, the transmitter coil can transmit electromagnetic energy to the wireless power receiver.

[0071] According to an embodiment, one or more processors (150) may control a wireless power transmitter (140) to transmit wireless power when a wireless power receiver is identified.

[0072] One or more processors (150) control the overall operation of the display device (100). Specifically, one or more processors (150) may be connected to each component of the display device (100) to control the overall operation of the display device (100).

[0073] One or more processors (150) can perform operations of the display device (100) according to various embodiments by executing at least one instruction stored in the memory (120).

[0074] The one or more processors (150) may include one or more of a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), an Accelerated Processing Unit (APU), a Many Integrated Core (MIC), a Digital Signal Processor (DSP), a Neural Processing Unit (NPU), a hardware accelerator, or a machine learning accelerator. The one or more processors (150) may control one or any combination of other components of the electronic device, and may perform operations related to communication or data processing. The one or more processors (150) may execute one or more programs or instructions stored in the memory (120). For example, the one or more processors may perform a method according to one or more embodiments of the present disclosure by executing one or more instructions stored in the memory (120).

[0075] When a method according to one or more embodiments of the present disclosure includes multiple operations, the multiple operations may be performed by one processor or by multiple processors. For example, when a first operation, a second operation, and a third operation are performed by a method according to one or more embodiments, the first operation, the second operation, and the third operation may all be performed by the first processor, or the first operation and the second operation may be performed by the first processor (e.g., a general-purpose processor) and the third operation may be performed by the second processor (e.g., an artificial intelligence-specific processor).

[0076] One or more processors (150) may be implemented as a single core processor including one core, or may be implemented as one or more multicore processors including multiple cores (e.g., homogeneous multicores or heterogeneous multicores). When one or more processors (150) are implemented as a multicore processor, each of the multiple cores included in the multicore processor may include an internal processor memory, such as a cache memory or an on-chip memory, and a common cache shared by the multiple cores may be included in the multicore processor. In addition, each of the multiple cores (or some of the multiple cores) included in the multicore processor may independently read and execute a program instruction for implementing a method according to one or more embodiments of the present disclosure, or all (or some) of the multiple cores may be linked to read and execute a program instruction for implementing a method according to one or more embodiments of the present disclosure.

[0077] When a method according to one or more embodiments of the present disclosure includes a plurality of operations, the plurality of operations may be performed by one core among the plurality of cores included in a multi-core processor, or may be performed by the plurality of cores. For example, when a first operation, a second operation, and a third operation are performed by a method according to one or more embodiments, the first operation, the second operation, and the third operation may all be performed by a first core included in the multi-core processor, or the first operation and the second operation may be performed by a first core included in the multi-core processor, and the third operation may be performed by a second core included in the multi-core processor.

[0078] In embodiments of the present disclosure, a processor may mean a system on a chip (SoC) in which one or more processors and other electronic components are integrated, a single-core processor, a multi-core processor, or a core included in a single-core processor or a multi-core processor, wherein the core may be implemented as a CPU, a GPU, an APU, a MIC, a DSP, an NPU, a hardware accelerator, or a machine learning accelerator, but embodiments of the present disclosure are not limited thereto.

[0079] In particular, one or more processors (150) according to an embodiment of the present disclosure control a display panel (110) to display content, and when a switchable mirror (200) is attached, can control (or adjust, change, etc.) the reflectivity of a mirror layer (210) of the switchable mirror (200).

[0080] FIG. 4 is a block diagram showing the configuration of a switchable mirror according to an embodiment of the present disclosure.

[0081] Referring to FIG. 4, the switchable mirror (200) may include a mirror layer (210), a wireless power receiver (220), a camera (230), and a connection unit (240).

[0082] According to an embodiment, a switchable mirror (200) is attached to a display device (100), is placed on the front of a display panel (110), and may include a mirror layer (210) whose reflectivity can be controlled.

[0083] According to an embodiment, the mirror layer (210) can control the reflectivity according to a control signal received from at least one of one or more processors (150) provided in the display device (100) or one or more processors (241) provided in the connection portion (240) of the switchable mirror (200).

[0084] In the present disclosure, the description of one or more processors (241) provided in the connection unit (240) is the same as the description of one or more processors (150) provided in the display device (100), and therefore, will be omitted.

[0085] When the reflectivity of the mirror layer (210) is adjusted to the maximum reflectivity according to an embodiment, the mirror layer (210) can operate in a mirror state that provides a mirror image corresponding to an object located in front of the switchable mirror (200).

[0086] When the reflectivity of the mirror layer (210) is adjusted to the minimum reflectivity according to an embodiment, the mirror layer (210) transmits all of the incident light and can operate in a clear state (or glass state) that transmits all of the light output by the display panel (110) to provide content.

[0087] According to an embodiment, a touch sensor that detects a touch operation in the form of a touch film, a touch sheet, a touch pad, etc. may be disposed on the front surface of the mirror layer (210) so as to be implemented to detect various types of touch inputs. For example, the mirror layer (210) may detect various types of touch inputs, such as a touch input by a user's hand, a touch input by an input device such as a stylus pen, and a touch input by a specific electrostatic material. Here, the input device may be implemented as a pen-type input device that may be referred to by various terms such as an electronic pen, a stylus pen, an S-pen, etc.

[0088] According to an embodiment, the mirror layer (210) can control the switchable mirror (200) by transmitting the detected touch input to one or more processors (241) provided in the switchable mirror (200), and can also control the display device (100) by transmitting the detected touch input to one or more processors (150) provided in the display device (100).

[0089] According to an embodiment, the switchable mirror (200) may include a wireless power receiver (220).

[0090] The wireless power receiver (220) may include a receiving coil (Rx Coil).

[0091] According to an embodiment, an induced electromotive force may be generated by a voltage applied to the transmitting coil of the wireless power transmitter (1400) or a current flowing through the transmitting coil. Here, the induced electromotive force has a unit of voltage. The receiving coil of the wireless power receiver (220) receives electromagnetic energy from the transmitting coil. For example, the receiving coil may receive power through magnetic coupling with the transmitting coil.

[0092] Next, the rectifier provided in the wireless power receiver (220) can rectify the power received through the receiving coil. For example, the rectifier can rectify the alternating current received through the receiving coil to generate a direct current. The rectifier can rectify and smooth the alternating voltage received through the receiving coil again to convert it into a direct current. Next, the switchable mirror (200) can be driven using the power rectified through the wireless power receiver (220).

[0093] However, it is not limited to this, and the switchable mirror (200) can of course be connected to the display device (100) by a wire to receive wired power.

[0094] According to an embodiment, the switchable mirror (200) can detect the surrounding environment of the switchable mirror (200) (e.g., an object located in front of the switchable mirror (200)) through a camera (230) placed in an area of ​​the mirror layer (210).

[0095] In the embodiment of the present disclosure, for convenience of explanation, it is assumed that the switchable mirror (200) includes a camera (230), but the present invention is not limited thereto, and it is of course possible for the display device (100) to include a camera.

[0096] According to an embodiment, the camera (230) can capture an image by capturing an object located in front of the switchable mirror (200).

[0097] According to an embodiment of the present disclosure, the camera (230) can convert a captured image into an electrical signal and generate image data based on the converted signal. For example, the camera (230) can convert a subject (e.g., an object positioned in front of the switchable mirror (200)) into an electrical image signal through a semiconductor optical element (CCD; Charge Coupled Device), amplify the converted image signal, convert it into a digital signal, and then signal process it. For example, the camera (230) can include at least one of a general (or basic) camera, an RGB camera, and an ultra-wide-angle camera.

[0098] However, it is not limited thereto, and the camera (230) may be implemented as a ToF (time-of-flight) sensor, a Lidar sensor, a radar sensor, an ultrasonic sensor, an infrared sensor, etc.

[0099] The camera (230) according to the embodiment may capture still images at a specific point in time, or may capture still images continuously (or in real time).

[0100] According to an embodiment, one or more processors (241) provided in the switchable mirror (200) or one or more processors (150) provided in the display device (100) can identify a context located in front of the switchable mirror (200) based on an image acquired through the camera (230). For example, one or more processors (150) can identify a context of a user located in front of the switchable mirror (200).

[0101] For example, one or more processors (150) may increase the reflectivity of the mirror layer (210) to provide a corresponding mirror image to the user when the user is positioned adjacent to (or approaching toward) the switchable mirror (200).

[0102] For example, one or more processors (150) may increase the reflectivity of the mirror layer (210) to provide a mirror image corresponding to the user when the user's movement is identified (e.g., the user is exercising).

[0103] For example, one or more processors (150) may reduce the reflectivity of the mirror layer (210) to provide content across the entire area of ​​the display panel (110) when the user moves away from the switchable mirror (200).

[0104] A detailed explanation of this will be provided later.

[0105] FIGS. 5 and 6 are drawings for explaining the structure of a switchable mirror according to an embodiment of the present disclosure.

[0106] A mirror layer (210) according to an embodiment of the present disclosure may include a polarizer, an upper glass, a lower glass, and a reflective polarizer.

[0107] According to an embodiment, a liquid crystal (LC) layer may be formed between the upper glass and the lower glass. The liquid crystal (LC) is in an intermediate state between a liquid and a crystal, and may have a structure in which rod-shaped molecules (liquid crystal molecules) are aligned in one direction similar to a solid crystal.

[0108] According to an embodiment, a polarizer may be implemented to transmit polarized light. According to an example, the upper glass and the lower glass may be implemented using TCO (Transparent Conductive Oxide) glass, but is not limited thereto.

[0109] Fig. 5 illustrates the mirror layer (210) when the voltage is turned off. When the voltage is turned off, the liquid crystal molecules maintain a vertical state, and the incident polarized light can be transmitted through the LC (liquid crystal) layer (210-3) as is and reflected toward the reflection axis of the reflective polarizer (210-4). Accordingly, the mirror layer (210) can be maintained in a mirror state.

[0110] For example, when electricity is not applied, the incident polarized light is reflected along the reflection axis of the reflective polarizer, so that the mirror function (hereinafter, Mirror state) of the mirror layer (210) can be provided, and as illustrated in FIG. 6, when electricity is applied, the incident polarized light rotates 90 degrees and transmits along the reflection axis of the reflective polarizer (210-4), so that the mirror state (e.g., clear state) of the mirror layer (210) can be maintained.

[0111] In addition, depending on the implementation example, a protective film that protects the polarizing plate, a film that classifies light from the polarizing plate, etc. may be further included.

[0112] FIG. 7 is a drawing for explaining a display device that transmits wireless power with a switchable mirror according to an embodiment of the present disclosure.

[0113] Referring to FIG. 7, a wireless power transmitter (140) is provided on the rear of a display device (100), and one or more processors (150) can control the wireless power transmitter (140) to transmit wireless power when attachment of a switchable mirror (200) is identified (or when a wireless power receiver (220) is positioned adjacent to it). Since the configurations of the wireless power transmitter (140) and the wireless power receiver (220) have been described above, a duplicate description will be omitted.

[0114] According to an embodiment, the display device (100) includes a plurality of sensors (160-1, ..., 160-n), and the plurality of sensors (160-1, ..., 160-n) are provided on the rear of the display device (100) and can detect the switchable mirror (200).

[0115] For example, one or more processors (150) can identify whether a switchable mirror (200) is attached or an area to which the switchable mirror (200) is attached (e.g., a portion of the entire area of ​​the display panel (110) covered by the switchable mirror (200), or a portion of the entire area of ​​the display panel (110) overlapping with the switchable mirror (200)) based on data acquired through a plurality of sensors (160-1, ..., 160-n).

[0116] According to an embodiment, each of the plurality of sensors (160-1, ..., 160-n) may include a magnetic sensor. One or more processors (150) may identify the attachment of the switchable mirror (200) when a magnetic force is detected through some of the plurality of magnetic sensors. According to an embodiment, one or more processors (150) may identify a portion of the entire area of ​​the display panel (110) that overlaps the switchable mirror (200) (or a portion of the area covered by the switchable mirror (200)) based on the positions of some of the magnetic sensors that detected the magnetic force.

[0117] For example, when a magnetic force is detected from the first sensor (160-1) to the fourth sensor (160-4) among the plurality of sensors (160-1, ..., 160-n), one or more processors (150) can identify an area corresponding to the first sensor (160-1) to the fourth sensor (160-4) among the entire area of ​​the display panel (110) as a part of the area overlapping the switchable mirror (200) (or a part of the area covered by the switchable mirror (200), or a part of the area overlapping the switchable mirror (200), etc.).

[0118] According to an embodiment, each of the plurality of sensors (160-1, ..., 160-n) may include an illuminance sensor. One or more processors (150) may identify the attachment of the switchable mirror (200) when a sudden decrease in illuminance value is detected through some illuminance sensors among the plurality of illuminance sensors. According to an embodiment, one or more processors (150) may identify a portion of the entire area of ​​the display panel (110) that overlaps the switchable mirror (200) (or a portion of the area covered by the switchable mirror (200)) based on the positions of some of the illuminance sensors where a sudden decrease in illuminance value is detected.

[0119] For example, when one or more processors (150) detect a sudden decrease in the illuminance value through the first sensor (160-1) to the fourth sensor (160-4) among the plurality of sensors (160-1, ..., 160-n), the processors (150) can identify an area corresponding to the first sensor (160-1) to the fourth sensor (160-4) among the entire area of ​​the display panel (110) as a partial area overlapping the switchable mirror (200).

[0120] However, the present invention is not limited thereto, and each of the plurality of sensors (160-1, ..., 160-n) may include various types of proximity sensors. For example, each of the plurality of sensors (160-1, ..., 160-n) may include an RFID (Radio-Frequency Identification) sensor (e.g., an RFID reader). For example, when an RFID tag equipped on the switchable mirror (200) (or the wireless power receiver (220) of the switchable mirror (200)) is detected through the first sensor (160-1) to the fourth sensor (160-4) among the plurality of sensors (160-1, ..., 160-n), one or more processors (150) can identify an area corresponding to the first sensor (160-1) to the fourth sensor (160-4) among the entire area of ​​the display panel (110) as a portion of the area overlapping the switchable mirror (200).

[0121] It is not limited thereto, and it is of course possible for multiple sensors (160-1, ..., 160-n) to be provided on the front of the display device (100) to detect the switchable mirror (200).

[0122] Referring to the side view of the switchable mirror (200) illustrated in FIG. 7, the switchable mirror (200) may include a mirror layer (210) that is positioned adjacent to the front of the display panel (110) when attached to the display panel (110), and a wireless power receiver (220) that is positioned adjacent to the rear of the display panel (110) when attached to the display panel.

[0123] According to an embodiment, the switchable mirror (200) connects the mirror layer (210) and the wireless power receiver (220), and may include a connecting portion (240) whose length can be manually or automatically adjusted to correspond to the thickness of the display panel (110).

[0124] According to an embodiment, the connecting portion (240) may include a control circuit having one or more processors (241) for controlling the switchable mirror (200).

[0125] For example, the connecting portion (240) has a screw, and by rotating the screw, the length of the connecting portion (240) can be adjusted to correspond to the thickness of the display panel (110).

[0126] It is not limited thereto, and the connecting portion (240) includes a sliding rail (or sliding guide), and the distance between the mirror layer (210) and the wireless power receiving portion (220) (i.e., the length of the connecting portion (240)) can be adjusted to correspond to the thickness of the display panel (110).

[0127] For example, the connecting portion (240) has a motor, and by driving the motor, the position of at least one of the mirror layer (210) or the wireless power receiving portion (220) can be adjusted forward / backward, thereby adjusting the length of the connecting portion (240) to correspond to the thickness of the display panel (110).

[0128] For example, the connecting portion (240) may of course include a length-adjustable joint, a piston (or cylinder) whose length can be adjusted using fluid or air, etc.

[0129] According to an embodiment, one or more processors (150) may control the wireless power transmitter (140) to transmit wireless power when the attachment of the switchable mirror (200) is identified (or, when the wireless power receiver (220) of the switchable mirror (200) is detected). According to an embodiment, in order for the wireless power receiver (220) to receive wireless power, the distance between the wireless power transmitter (140) and the wireless power receiver (220) must be within a threshold distance, and therefore, the one or more processors (150) may control the connection unit (240) so that the distance between the wireless power transmitter (140) and the wireless power receiver (220) becomes less than or equal to the threshold distance.

[0130] For example, one or more processors (150) may control the connection (240) so that the wireless power receiver (220) is positioned adjacent to the wireless power transmitter (140) when the attachment of the switchable mirror (200) is identified but the wireless power receiver (220) is not detected.

[0131] For example, when the wireless power transmitter (140) transmits wireless power but the wireless power receiver (220) does not receive wireless power, one or more processors (150) may control the connection unit (240) so that the wireless power receiver (220) is positioned adjacent to the wireless power transmitter (140).

[0132] According to an embodiment of the present disclosure, in order to prevent the occurrence of problems such as failures in the elements (components) provided in each of the display device (100) and the switchable mirror (200) due to friction, contact, or physical collision between the display device (100) and the switchable mirror (200) during the process of attaching or detaching the switchable mirror (200) to the display device (100), the surface of the mirror layer (210) of the switchable mirror (200) that comes into contact with the display panel (110) may include a transparent protective film to protect it from scratches and minor damage and to absorb shock. In addition, the wireless power receiving unit (220) and the connecting unit (240) of the switchable mirror (200) may include a shaving protection film that comes into contact with the display device (100).

[0133] According to an embodiment, the surface of the mirror layer (210) that contacts the display panel (110) includes a transparent protective film to transmit light output by the display panel (110) to provide content, and the surface of the wireless power receiving unit (220) and the connecting unit (240) of the switchable mirror (200) that contacts the display device (100) may include a transparent protective film or an opaque protective film (or various types of physical buffers).

[0134] FIG. 8 is a drawing for explaining a switchable mirror with adjusted reflectivity according to an embodiment of the present disclosure.

[0135] Referring to FIGS. 1 and 8, one or more processors (150) can control the display panel (110) to display content on the entire area of ​​the display panel (110).

[0136] According to an embodiment, one or more processors (150) can identify a portion of the entire area of ​​the display panel (110) that overlaps the switchable mirror (200) when the switchable mirror (200) is attached to the front of the display panel (110).

[0137] According to an embodiment, one or more processors (150) may convert the content (e.g., resize the content, adjust the resolution of the content (e.g., up-scaling, down-scaling, etc.)) based on the size of the remaining area to display the content in the remaining area excluding a portion of the entire area.

[0138] According to an embodiment, one or more processors (150) may control the display panel (110) to display the converted content in the remaining area.

[0139] According to an embodiment, one or more processors (150) may increase the reflectivity of the mirror layer (210) of the switchable mirror (200) to provide a mirror image of a user positioned in front of the switchable mirror (200) in a portion of the entire area of ​​the display panel (110) that overlaps the switchable mirror (200).

[0140] Referring to FIG. 8, when a switchable mirror (200) is attached to a display device (100), one or more processors (150) can adjust the reflectivity of the mirror layer (210) to the maximum reflectivity to operate some area overlapping the switchable mirror (200) in a mirror state.

[0141] Meanwhile, in the present disclosure, for the convenience of explanation, it is assumed that the vertical length of the switchable mirror (200) is greater than the vertical length of the display device (100), but of course, it is not limited thereto.

[0142] For example, when the switchable mirror (200) is attached, one or more processors (150) can identify a vertical region that includes a portion of the area overlapping the switchable mirror (200). For example, one or more processors (150) can identify a vertical region that includes a portion of the area overlapping the switchable mirror (200) and has a width equal to the horizontal width of the portion of the area. Then, one or more processors (150) can convert the content to correspond to the size of the remaining area in order to display the content in the remaining area excluding the vertical region.

[0143] FIG. 9 is a drawing for explaining a display device that displays content in an entire area according to an embodiment of the present disclosure.

[0144] Referring to FIG. 9, according to an embodiment, one or more processors (150) can adjust the reflectivity of the mirror layer (210) to a minimum reflectivity to display content over the entire area of ​​the display panel (110), even if a switchable mirror (200) is attached.

[0145] For example, if one or more processors (150) determine that the genre of the content is a preset genre (e.g., movie, concert, etc.) based on metadata of the content, or if the external device providing the content is a preset device (e.g., external streaming server (OTT server), console game device, etc.), the size of the content is not changed even if the attachment of the switchable mirror (200) is identified, and the content can be displayed through the entire area of ​​the display panel (110).

[0146] According to an embodiment, one or more processors (150) adjust the reflectivity of the mirror layer (210) to the minimum reflectivity to operate the mirror layer (210) in a clear state (or glass state) in order to minimize inconvenience to a user viewing content due to the attachment of the switchable mirror (200), and display content over the entire area of ​​the display panel (110).

[0147] According to an embodiment, one or more processors (150) may increase the brightness of a backlight or self-luminous element corresponding to a portion of an area overlapping the switchable mirror (200) relatively to the brightness of a backlight or self-luminous element corresponding to the remaining area.

[0148] According to an embodiment, one or more processors (150) may increase the brightness of some areas overlapping the switchable mirror (200) relatively more than the brightness of the remaining areas to compensate for brightness reduction due to the transmittance of the mirror layer (210).

[0149] However, this is an example for the convenience of explanation, and the reflectivity of the mirror layer (210) is controlled according to user input (e.g., user input via a remote control device, user input via a user voice command, etc.), and content can be displayed through the entire area of ​​the display panel (110) even when the switchable mirror (200) is attached.

[0150] For example, one or more processors (150) may adjust the reflectivity of the mirror layer (210) to less than the maximum reflectivity based on user input, and may display content over the entire area of ​​the display panel (110), and some areas overlapping the switchable mirror (200) may provide both content and a mirror image.

[0151] FIG. 10 is a drawing for explaining a display device that provides a mirror image to a portion of an area using a switchable mirror according to an embodiment of the present disclosure.

[0152] Referring to FIG. 10, one or more processors (150) can control the switchable mirror (200) and the display panel (110) to provide only a mirror image through a portion of the entire area of ​​the display panel (110) that overlaps the switchable mirror (200), and to prevent the remaining area from providing content.

[0153] According to an embodiment, one or more processors (150) may adjust the reflectivity of the mirror layer (210) to the maximum reflectivity, and may turn off the backlight corresponding to the remaining area or turn off the self-luminous element to increase power efficiency without displaying content in the area not covered by the switchable mirror (200) (or the area not overlapping the switchable mirror (200)) (i.e., the remaining area).

[0154] For example, if the display panel (110) includes a non-luminous element and a backlight, one or more processors (150) can turn off the backlight corresponding to the remaining area except for a portion of the entire area of ​​the display panel (110) that overlaps the switchable mirror (200).

[0155] For example, if the display panel (110) includes a self-luminous element, one or more processors (150) can turn off the backlight corresponding to the remaining area except for a portion of the entire area of ​​the display panel (110) that overlaps the switchable mirror (200).

[0156] However, the present invention is not limited thereto, and one or more processors (150) may adjust the reflectivity of the mirror layer (210) between a minimum reflectivity and a maximum reflectivity to provide both a mirror image and sub-content in an area overlapping the switchable mirror (200), and control the display panel (110) to display the sub-content in an area overlapping the switchable mirror (200).

[0157] Here, the sub-content may include sub-content such as a widget (e.g., a UI (User Interface) smaller than a preset size for providing weather information, schedule information, traffic information, stock (or exchange rate) information, etc.) and notifications that are different from the content displayed by the display panel (110) before the switchable mirror (200) is attached to the display device (100).

[0158] According to an embodiment, the display device (100) may receive data corresponding to sub-content (e.g., at least one of a widget and a notification) from an external device and control the display panel (110) to display the sub-content based on the received data. However, the present invention is not limited thereto, and the display device (100) may store the sub-content and control the display panel (110) to display the stored sub-content.

[0159] However, it is not limited thereto, and the sub-content corresponds to an object located in front of the switchable mirror (200) and may include a virtual object adjusted (aligned) on the mirror provided by the mirror layer (210).

[0160] For example, one or more processors (150) can capture an object located in front of the switchable mirror (200) through a camera (230) included in the switchable mirror (200) and, when an image is acquired, display a virtual object positioned to contact (or come into contact with) a mirror provided by the mirror layer (210) based on the object included in the acquired image in an area overlapping the switchable mirror (200).

[0161] FIG. 11 is a drawing for explaining a display device that provides converted content and a mirror image according to an embodiment of the present disclosure.

[0162] Referring to FIG. 11, when a switchable mirror (200) is attached, one or more processors (150) can identify an area of ​​the entire display panel (110) except for an area that overlaps the switchable mirror (200).

[0163] If the remaining area is divided into a plurality of sub-areas according to an embodiment, one or more processors (150) can display the content in the first sub-area by converting the content to correspond to the size of a first sub-area having a relatively large size among the plurality of sub-areas.

[0164] For example, as illustrated in FIG. 11, if the remaining area is divided into a first sub-area and a second sub-area due to some area overlapping the switchable mirror (200), one or more processors (150) can display content in the first sub-area that is relatively larger among the first sub-areas and the second sub-areas.

[0165] Meanwhile, only an embodiment in which one or more processors (150) convert content based on the size of the remaining area and then display the content has been described, but the present invention is not limited thereto, and it is of course possible for one or more processors (150) to downscale (or upscale) the content based on the resolution of the remaining area and then display the content.

[0166] In FIG. 11, according to an embodiment, one or more processors (150) may not display content in a second sub-area having a relatively small size among a plurality of sub-areas, but the present invention is not limited thereto.

[0167] FIG. 12 is a drawing for explaining a display device that provides different contents to a part of the entire area and the remaining area according to an embodiment of the present disclosure.

[0168] Referring to FIG. 12, one or more processors (150) can display content different from the content to be displayed in the first sub-region in a second sub-region having a relatively small size among the plurality of sub-regions.

[0169] For example, one or more processors (150) display content through a display panel (110), and if the remaining area except for some areas overlapping the switchable mirror (200) is divided into a plurality of sub-areas, different content can be displayed in each of the plurality of sub-areas.

[0170] For example, one or more processors (150) may sequentially display content in a first sub-area that is relatively large among a plurality of sub-areas, and display different content in a second sub-area that is relatively small.

[0171] For example, when the display device (100) receives content from each of the first external device and the second external device, one or more processors (150) can display the content received from the first external device in the first sub-area and display the content received from the second external device in the second sub-area.

[0172] As another example, one or more processors (150) can identify a user's context through a camera (230) included in a switchable mirror (200) and display content corresponding to the identified context in a second sub-area that is relatively smaller among a plurality of sub-areas.

[0173] For example, one or more processors (150) may display exercise-related content in the second sub-area if the user's context is identified as 'exercise' based on an image acquired through the camera (230).

[0174] For example, if the user's context is identified as 'getting ready to go out' based on an image acquired through the camera (230), one or more processors (150) may display weather-related content, schedule-related content, coordination-related content, etc. in the second sub-area.

[0175] For example, one or more processors (150) may display concentration-enhancing content, etc. in the second sub-area if the user's context is identified as 'studying' based on an image acquired through the camera (230).

[0176] According to an embodiment, one or more processors (150) may control the reflectivity of the mirror layer (210) in a portion of the area overlapping the switchable mirror (200) to provide a mirror image and display content (e.g., sub-content) related to the user's context.

[0177] However, the present invention is not limited thereto, and one or more processors (150) may identify the context of a space (or the surrounding environment of the display device (100)) in addition to the user's context, and display content corresponding to the identified context.

[0178] For example, if there is no user in the space where the display device (100) is located or the illuminance is above a threshold value (or below a threshold value), one or more processors (150) may display preset content in at least one of a portion of the area or the remaining areas, or control the reflectivity of the switchable mirror (200) to a preset value.

[0179] FIG. 13 is a drawing for explaining a display device that displays content received from a first external device and content received from a second external device according to an embodiment of the present disclosure.

[0180] Referring to FIG. 13, when a switchable mirror (200) is attached, one or more processors (150) can display content received from a first external device (10) in an area remaining except for a portion overlapping the switchable mirror (200), and display content received from a second external device (20) in a portion of the area.

[0181] For example, one or more processors (150) can display content displayed by the display panel (110) before the switchable mirror (200) is attached, in succession to the remaining area, and can display different content through some area overlapping the switchable mirror (200).

[0182] For example, one or more processors (150) included in a display device (100) that is being mirrored with a second external device (20) can display content received from the second external device (20) through a portion of the area overlapping the switchable mirror (200).

[0183] For example, one or more processors (150) may identify the security level (or privacy level) of each of the plurality of external devices, and content received from an external device (e.g., the first external device (10)) with a low security level (or low privacy level) may be displayed through the remaining area.

[0184] According to an embodiment, one or more processors (150) may display content received from an external device having a high security level among a plurality of external devices (e.g., a second external device (20)) through a certain area.

[0185] However, this is an example for convenience of explanation and is not limited thereto.

[0186] For example, one or more processors (150) may display content (e.g., non-face-to-face meetings, non-face-to-face classes, etc.) that displays an image acquired through a camera (230) provided in the switchable mirror (200) through a portion of an area overlapping the switchable mirror (200) to provide the content together with the mirror image. In addition, one or more processors (150) may adjust the reflectivity of the mirror layer (210) provided in the switchable mirror (200) to exceed the minimum reflectivity and be less than the maximum reflectivity.

[0187] FIG. 14 is a diagram illustrating a display device that controls reflectivity based on a user's context and provides at least one of a widget and a notification according to an embodiment of the present disclosure.

[0188] Referring to FIG. 14, a camera (230) provided in a switchable mirror (200) can detect the surrounding environment of the switchable mirror (200) (e.g., an object located in front of the switchable mirror (200)).

[0189] According to an embodiment, one or more processors (150) can adjust the reflectivity of the mirror layer (210) to a minimum reflectivity and display content over the entire area of ​​the display panel (110) if no user is detected in front of the switchable mirror (200) or if the user is spaced apart from the display device (100) by a threshold distance or more.

[0190] According to an embodiment, one or more processors (150) may increase the reflectivity of the mirror layer (210) to provide a mirror image corresponding to the user when the user is positioned adjacent to the switchable mirror (200) (or is approaching the switchable mirror (200)) or when movement of the user is identified (e.g., when the user is exercising) based on an image acquired through the camera (230).

[0191] Additionally, one or more processors (150) can display content corresponding to the user's context (e.g., exercise, etc.) in the remaining area.

[0192] For example, if the remaining area is divided into multiple sub-areas, one or more processors (150) can provide content to a first sub-area that is relatively large among the multiple sub-areas, and provide content related to the user's context to a second sub-area that is relatively small.

[0193] According to an embodiment, one or more processors (150) may reduce the reflectivity of the mirror layer (210) based on an image acquired through the camera (230) when the user moves away from the switchable mirror (200) or when the user is not detected.

[0194] However, the present invention is not limited thereto, and the memory (120) provided in the display device (100) stores information on reflectivity corresponding to each of a plurality of contexts, and one or more processors (150) can identify a context based on an image acquired through a camera (230) and identify a reflectivity corresponding to the identified context based on the information stored in the memory (120). Subsequently, the one or more processors (150) can control the mirror layer (210) with the identified reflectivity.

[0195] For example, one or more processors (150) can input an image acquired through a camera (230) into a neural network model trained to identify a user's context, identify the context, and identify a reflectance corresponding to the identified context based on information stored in the memory (120).

[0196] However, the present invention is not limited thereto, and one or more processors (150) may input an image acquired through the camera (230) into a neural network model trained to acquire a reflectance corresponding to the image acquired through the camera (230), thereby identifying the reflectance.

[0197] It is to be understood that the neural network model according to various embodiments of the present disclosure may be included in at least one of the display device (100) or the switchable mirror (200), or may be included in an external server capable of communicating with the display device (100).

[0198] Returning to FIG. 2, one or more processors (150) can display content in the remaining area, and when the size of the remaining area changes due to movement of the switchable mirror (200), the content can be converted and displayed to correspond to the changed size.

[0199] For example, one or more processors (150) can transform content in real time by reflecting changes in the size of the remaining area according to the movement of the switchable mirror (200).

[0200] FIG. 15 is a flowchart for explaining a method for controlling a display device according to an embodiment of the present disclosure.

[0201] A method for controlling a display device according to an embodiment of the present disclosure first controls a display panel to display content over the entire area (S1510).
