[0046] In the following description, embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings.

[0047] Figure 1 This is a diagram illustrating the characteristics of a mirrored display according to an embodiment of the present disclosure.

[0048] The display device 100 according to embodiments of the present disclosure can be implemented as various types of mirror display devices that can be installed in various spaces requiring mirror surfaces and can transmit information while providing mirror functionality. Here, "mirror display" is a compound word of "mirror" and "display," where "mirror" means a mirror surface and "display" means a work that visually expresses information.

[0049] like Figure 1 As shown, the display device 100 may include a mirror display 110, and the mirror display 110 may include a switchable mirror 111 and a display panel 112.

[0050] For example, the display device 100 may include a display panel 112 for displaying images and a switchable mirror 111 disposed on the front surface of the display panel 112 and configured to adjust the reflectivity.

[0051] According to an embodiment, the switchable mirror 111 can provide mirror functionality by being implemented as a glass plate or a transparent plastic plate, wherein a portion of the glass plate or transparent plastic plate is deposited to reflect incident light, while other portions are deposited.

[0052] According to an embodiment, the display panel 112 may include a display comprising a self-emissive element or a non-self-emissive element and a backlight. For example, the display panel 112 may be implemented as a variety of displays, such as a liquid crystal display (LCD), an organic light-emitting diode (OLED) display, light-emitting diodes (LEDs), micro LEDs, mini LEDs, plasma display panels (PDPs), quantum dot (QD) displays, quantum dot light-emitting diodes (QLEDs), etc.

[0053] In this disclosure, for ease of explanation, the location of User 1 will be defined as follows: Figure 1 The front side of the display device 100 shown.

[0054] Figure 2 This is a block diagram illustrating the configuration of a display device according to an embodiment of the present disclosure.

[0055] according to Figure 2 The display device 100 may include a mirror display 110, a camera 120, a memory 130, and at least one processor 140.

[0056] The mirror display 110 can be implemented as a display including self-emissive elements, or as a display including non-self-emissive elements and a backlight. For example, the mirror display 110 can be implemented as various forms of displays, such as liquid crystal displays (LCDs), organic light-emitting diode (OLED) displays, light-emitting diodes (LEDs), micro LEDs, mini LEDs, plasma display panels (PDPs), quantum dot (QD) displays, quantum dot light-emitting diodes (QLEDs), etc.

[0057] Inside the mirror display 110, a driving circuit and a backlight unit, which can be implemented in the form of a-Si TFT, low-temperature polycrystalline silicon (LTPS) TFT, organic TFT (OTFT), etc., may also be included. According to an embodiment, a touch sensor, which takes the form of a touch film, touch sheet, touchpad, etc., and detects touch operations, is arranged on the front surface of the mirror display 110, and this touch sensor can be implemented to detect various types of touch input. For example, the mirror display 110 can detect various types of touch input, such as touch input from a user's hand, touch input from an input device (e.g., a stylus), touch input from a specific electrostatic material, etc. Here, the input device can be implemented as a pen-type input device, which can be referred to by various terms, such as electronic pen, stylus, S-pen, etc. According to an embodiment, the mirror display 110 can be implemented as a flat panel display, a curved display, a flexible display that can be folded and / or rolled up, etc.

[0058] The mirror display 110 can be implemented as a display that provides both mirror and display functions.

[0059] For example, the mirror display 110 can be implemented in the form of a half mirror (or mirror film) that has been added to a conventional general-purpose display panel. Figure 3 and Figure 4 The display 210 shown illustrates an LCD including a semi-reflective mirror as an example of the implementation of the mirror display 110, and is also referred to as a liquid crystal display. An LCD can operate based on the principle that when light is generated at a backlight, the light passes through the molecules of the liquid crystal, thereby obtaining the desired image.

[0060] Figure 3 and Figure 4 This is a diagram illustrating the operation of a switchable mirror according to an embodiment of the present disclosure.

[0061] The switchable mirror 111 according to embodiments of the present disclosure can be implemented in the form of a polarizer, an upper glass, a lower glass, and a reflective polarizer.

[0062] According to an embodiment, a liquid crystal (LC) layer can be formed between an upper glass and a lower glass. The liquid crystal (LC) can have a structure in which rod-shaped molecules (liquid crystal molecules) are oriented in one direction, similar to a solid crystal in an intermediate state between liquid crystal and crystal.

[0063] According to an embodiment, the polarizer can be configured to allow polarized light to pass through. Furthermore, according to an embodiment, the upper and lower glass can be made of transparent conductive oxide (TCO) glass, but are not limited thereto.

[0064] Figure 3 The switchable mirror 111 is shown when the voltage is off. When the voltage is off, the liquid crystal molecules can remain in a vertical state, and the incident polarized light can pass through the liquid crystal (LC) layer 111-3 as is and can be reflected to the reflection axis of the reflective polarizer 111-4. Therefore, the switchable mirror 111 can remain in a mirror state.

[0065] For example, since the incident polarized light can be reflected to the reflection axis of the reflective polarizer when no electricity is applied, the mirror function of the switchable mirror 111 (hereinafter referred to as the mirror state) can be maintained. Furthermore, as... Figure 4 As shown, when an electric current is applied, the incident polarized light can rotate 90 degrees and pass through the reflection axis of the reflective polarizer 111-4, thus maintaining the transparent state of the switchable mirror 111 (hereinafter referred to as the clear state).

[0066] The display device 100 may also include a protective film configured to protect the polarizer, a film configured to classify the light on the polarizer, etc.

[0067] refer to Figure 2 The camera 120 can acquire images by capturing the surrounding environment of the display device 100 (at least one of the front surface, rear surface, or side surface).

[0068] According to embodiments of this disclosure, camera 120 can convert captured images into electrical signals and generate image data based on the converted signals. For example, camera 120 can convert an object into an electrical image signal using a charge-coupled device (CCD), amplify the converted image signal, convert it into a digital signal, and then perform signal processing. For example, camera 120 may include at least one of a general-purpose (or basic) camera, an RGB camera, or an ultra-wide-angle camera.

[0069] However, this is just an example, and the camera 120 can be implemented as a time-of-flight (ToF) sensor, lidar sensor, radar sensor, ultrasonic sensor, infrared sensor, etc.

[0070] According to the embodiment, the camera 120 can capture still images at a specific point in time, or capture still images continuously (or in real time).

[0071] For example, camera 120 can capture the surrounding environment of display device 100 and obtain an image including the surrounding environment of display device 100 (e.g., the front surface of mirror display 110).

[0072] As an example, camera 120 can obtain an image corresponding to the mirror image that can be provided by mirror display 110 based on the mirror function of mirror display 110. For example, if an object or user (hereinafter referred to as the object) is located in front of mirror display 110, display device 100 can provide a mirror image corresponding to the object through mirror display 110, and obtain an image including the object with the object as the subject through camera 120.

[0073] According to one or more embodiments, memory 130 can store data.

[0074] The memory 130 may be embedded in the display device 100, or it may be attached to or detached from the display device 100 depending on the purpose of the stored data. For example, in the case of data used to drive the display device 100, the data may be stored in the memory embedded in the display device 100, and in the case of data used for extended functions of the display device 100, the data may be stored in a memory that can be attached to or detached from the display device 100. When the memory is embedded in the display device 100, the memory may be implemented as at least one of volatile memory (e.g., dynamic RAM (DRAM), static RAM (SRAM), or synchronous dynamic RAM (SDRAM)). In addition, in the case of a memory that can be attached to or removed from the display device 100, the memory can be implemented in the form of a memory card (e.g., Compact Flash (CF), Secure Digital (SD), Micro-SD, Mini-SD, xD, Multimedia Card (MMC), etc.) and an external memory that can be connected to a USB port (e.g., a USB memory).

[0075] According to an embodiment, the memory 130 may store a computer program including at least one instruction for controlling the display device 100.

[0076] According to an embodiment, the memory 130 may store content received from an external device (e.g., a source device), an external storage medium (e.g., a USB), an external server (e.g., a webhard), etc. Alternatively, the memory 130 may store images acquired by a camera 120 disposed on the display device 100.

[0077] According to an embodiment, the memory 130 may store various information required for image quality processing, such as information, algorithms, image quality parameters, etc., for performing at least one of noise reduction, detail enhancement, tone mapping, contrast enhancement, color enhancement, or frame rate conversion. Furthermore, the memory 130 may store intermediate images generated through image processing and images generated based on depth information.

[0078] According to an embodiment, memory 130 may be implemented as a single memory storing data generated in various operations according to the present disclosure. However, according to an embodiment, memory 130 may also be implemented as multiple memories that respectively store different types of data or respectively store data generated in different steps.

[0079] In addition, the memory 130 can store various types of data, programs, or applications used to drive / control the display device 100. Furthermore, the memory 130 may 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, and a voice database (DB) or a motion database (DB).

[0080] In the foregoing embodiments, it was explained that various types of data are stored in the external memory of at least one processor 140, but at least some of the aforementioned data may be stored in the internal memory of at least one processor 140.

[0081] At least one processor 140 can control the overall operation of the display device 100. At least one processor 140 can be connected to each component of the display device 100 and control the overall operation of the display device 100.

[0082] At least one processor 140 can perform the operation of the display device 100 according to various embodiments by executing at least one instruction stored in the memory 130.

[0083] At least one processor 140 may include one or more of a central processing unit (CPU), graphics processing unit (GPU), accelerated processing unit (APU), integrated many-core processor (MIC), digital signal processor (DSP), neural processing unit (NPU), hardware accelerator, or machine learning accelerator. At least one processor 140 may control one or a random combination of other components of the display device 100 and perform operations related to communication or data processing. Furthermore, at least one processor 140 may execute one or more programs or instructions stored in memory. For example, at least one processor 140 may perform a method according to one or more embodiments of this disclosure by executing one or more instructions stored in memory.

[0084] In cases where a method according to one or more embodiments of this disclosure includes multiple operations, the multiple operations may be executed by a single 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, all of the first, second, and third operations may be executed by a first processor, or the first and second operations may be executed by a first processor (e.g., a general-purpose processor), and the third operation may be executed by a second processor (e.g., an artificial intelligence-specific processor).

[0085] At least one processor 140 may be implemented as a single-core processor including one core, or it may be implemented as one or more multi-core processors including multiple cores (e.g., multiple cores of the same type or multiple cores of different types). When at least one processor 140 is implemented as a multi-core processor, each of the multiple cores included in the multi-core processor may include the processor's internal memory, such as cache memory, on-chip memory, etc., and a common cache shared by the multiple cores may be included in the multi-core processor. Furthermore, each (or some) of the multiple cores included in the multi-core processor may independently read and execute program instructions for implementing the methods according to one or more embodiments of the present disclosure, or multiple whole cores (or some cores) may be linked together and read and execute program instructions for implementing the methods according to one or more embodiments of the present disclosure.

[0086] In cases where a method according to one or more embodiments of this disclosure includes multiple operations, the multiple operations may be executed by one of a plurality of cores included in a multi-core processor, or they may be implemented by a plurality of cores. For example, when the first operation, the second operation, and the third operation are performed by the method according to one or more embodiments, all of the first operation, the second operation, and the third operation may be executed by the first core included in the multi-core processor, or the first operation and the second operation may be executed by the first core included in the multi-core processor, and the third operation may be executed by the second core included in the multi-core processor.

Furthermore, the core may be implemented as a CPU, GPU, APU, MIC, DSP, NPU, hardware accelerator, or machine learning accelerator, etc., but embodiments of this disclosure are not limited thereto.

[0088] Figure 5 This is a diagram illustrating a display device that provides a mirror image and content corresponding to an object according to an embodiment of the present disclosure.

[0089] At least one processor 140 according to embodiments of the present disclosure can display content A via the display function of the mirror display 110. Through the mirror function of the mirror display 110, at least one processor 140 can provide a mirror image 2 corresponding to object 1.

[0090] The mirror display 110 according to embodiments of the present disclosure may include a plurality of blocks. At least one processor 140 according to embodiments may control each of the plurality of blocks on a block-by-block basis. As an example, the mirror display 110 may include a plurality of blocks arranged in a matrix (e.g., n × m form).

[0091] As an example, each of the multiple blocks can be implemented with the same size (or the same resolution), or with different sizes (or different resolutions).

[0092] In the following text, for ease of explanation, it will be assumed that each of the plurality of blocks is implemented with the same size (or the same resolution), and that the plurality of blocks are arranged in a matrix and implemented in a quadrilateral form in an embodiment of the mirror display 110, but is not limited thereto.

[0093] According to an embodiment, at least one processor 140 can provide content A through a first of a plurality of blocks.

[0094] For example, at least one processor 140 can display content A by controlling a first block of a plurality of blocks to perform a display function, and provide a mirror image 2 corresponding to object 1 by controlling a second block of a plurality of blocks to perform a mirror function.

[0095] In the foregoing embodiment, the first block that performs the display function under the control of at least one processor 140 can simultaneously perform the mirror function.

[0096] For example, at least one processor 140 can individually control the reflectivity of each of the plurality of blocks, and if the reflectivity of each of the first blocks performing the display function exceeds 0%, the first block can display content A while providing a mirror image 2 of object 1 located on the front side of the mirror display 110.

[0097] refer to Figure 5 At least one processor 140 can display content A through a first block of a plurality of blocks and provide mirror 2 through a second block of a plurality of blocks.

[0098] As an example, at least one processor 140 may control the reflectivity of each of the first blocks of content A to be less than or equal to a threshold (e.g., 0% reflectivity) to increase the visibility of content A.

[0099] Figure 6 This is a diagram illustrating a display apparatus for providing mirroring and content by using an image of a captured object according to an embodiment of the present disclosure.

[0100] refer to Figure 6 At least one processor 140 can provide content A through a first block of a plurality of blocks 110-1, ..., 110-n, and provide a portion 2-1 of a mirror image 2 corresponding to an object 1 located on the front side of the mirror display 110 by controlling a second block of the plurality of blocks 110-1, ..., 110-n with a first reflectivity.

[0101] For example, at least one processor 140 may control the reflectivity of each of the second blocks of the reflective object 1 (or, content A not displayed) at a first reflectivity (e.g., maximum reflectivity (100%)) to increase the visibility of the mirror 2.

[0102] According to an embodiment, at least one processor 140 can control each of the plurality of blocks 110-1, ..., 110-n constituting the mirror display 110 on a block-by-block basis. Thus, at least one third block in the first block that displays content A, including the boundary of content A, may include an area that does not provide content A or mirror 2.

[0103] For example, at least one third block within the first block displaying content A, including the boundary of content A, may include the remaining area other than the area displaying content A. According to an embodiment, at least one processor 140 may control the reflectivity of the first block to be less than or equal to a threshold for the visibility of content A (e.g., 0% reflectivity), so the remaining area of ​​at least one third block may be blank space that does not provide content A or mirror 2.

[0104] According to an embodiment, there may be a problem where the user of the display device 100 feels a parallax due to the gap between the content A and the portion 2-1 of the mirror 2.

[0105] At least one processor 140 according to embodiments of the present disclosure can obtain an image of object 1 captured by camera 120. At least one processor 140 can identify, based on the obtained image, the remaining portion 2-2 (e.g., the second portion of the image) of mirror 2 provided by the first block 10 of display content A (i.e., the portion other than portion 2-1 of mirror 2 provided by the second block in mirror 2).

[0106] According to an embodiment, at least one processor 140 can obtain the remainder 2-2 of the image 2 from the image, and display the remainder 2-2 of the image 2 and the content A through the first block 10 by overlaying the content A with the remainder 2-2 of the image 2.

[0107] According to an embodiment, at least one processor 140 can control the first blocks 10 displaying content A such that they not only display content A, but also display the remaining portion 2-2 of mirror 2 and content A by overlapping content A with the remaining portion 2-2 of mirror 2. As described above, the remaining portion of the image can also be referred to as the "second portion" of the mirror.

[0108] like Figure 6 As shown, at least one third block in the first block 10 of displaying content A, including the boundary of content A, can display the remaining part 2-2 of mirror 2 in part 2-1 of mirror 2, instead of displaying the remaining part 2-2 of mirror 2 in a blank space that provides neither content A nor mirror 2, thereby solving the problem of parallax perception for the user.

[0109] Figure 6 The boundary lines between the multiple blocks 110-1, ..., 110-n shown are randomly drawn lines for ease of illustration. Furthermore, according to the embodiment example, the multiple blocks 110-1, ..., 110-n are connected to form the mirror display 110, which may prevent the user from recognizing them. Figure 6 The boundary line shown.

[0110] Figure 7This is a diagram used to illustrate the first block of display content according to an embodiment of the present disclosure.

[0111] refer to Figure 7 At least one processor 140 can display content A through the first block 10 of a plurality of blocks 110-1, ..., 110-n, and identify the boundaries of the first block 10 that include content A. Figure 7 At least one third block 10-1 (in the dashed line).

[0112] like Figure 7 As shown, at least one third block 10-1 may include the area other than the area where content A is displayed, and the area other than the area where content A is displayed may be blank space where content A or mirror 2 is not provided.

[0113] According to an embodiment, since at least one third block 10-1 may include the boundary of content A, at least one processor 140 can control at least one third block 10-1 to display the remainder 2-2 of mirror 2 in the remaining areas other than the area where content A is displayed.

[0114] According to the embodiment, the remaining blocks 10-2 in the first block 10, except for at least one third block 10-1, may not include the boundary of content A, and all areas can display content A without blank spaces.

[0115] Figure 8 It is a graph used to illustrate the first to third reflectances according to embodiments of the present disclosure.

[0116] According to an embodiment, at least one processor 140 can control the reflectivity of each of a plurality of blocks 110-1, ..., 110-n on a block-by-block basis.

[0117] refer to Figure 8 At least one processor 140 can control a second block among a plurality of blocks 110-1, ..., 110-n, excluding the first block 10 displaying content A, with a first reflectivity.

[0118] For example, at least one processor 140 can control a second block in addition to the first block 10 of content A, which is displayed at maximum reflectivity (e.g., 100%), to increase the visibility of the mirror 2 corresponding to object 1.

[0119] At least one processor 140 according to an embodiment can control the boundary of the first block 10 containing content A to be displayed with a second reflectivity. Figure 8 At least one third block 10-1 (in the dashed line).

[0120] According to an embodiment, at least one processor 140 can control the remaining blocks 10-2 of the first block 10 that display content A with a third reflectivity, excluding at least one third block 10-1.

[0121] According to an embodiment, at least one processor 140 can control the display of the remaining blocks 10-2 of the first block 10 of content A, excluding at least one third block 10-1, with minimum reflectivity (e.g., 0%) to increase the visibility of content A.

[0122] According to an embodiment, at least one processor 140 can control the display of the boundary of content A within the first block 10, which includes content A, at a third reflectance between a first reflectance and a second reflectance (e.g., between 0% and 100%). Figure 8 At least one third block 10-1 (in the dashed line).

[0123] According to an embodiment, at least one processor 140 can identify the remaining portion 2-2 of mirror image 2 based on an image obtained by camera 120, and display the remaining portion 2-2 of mirror image 2 by at least one third block 10-1.

[0124] According to an embodiment, when at least one third block 10-1 is controlled with a third reflectivity between the first and second reflectivity, at least one processor 140 can display the remainder 2-2 and content A of the mirror image 2, and simultaneously provide the mirror image 2 through the reflective object 1.

[0125] Figure 9 This is a diagram illustrating a display device according to an embodiment of the present disclosure that controls each of the first to third reflectivities by sensing the amount of external light.

[0126] The display device 100 according to embodiments of the present disclosure may further include a sensor for sensing external light.

[0127] According to embodiments, the sensor can detect at least one of various characteristics such as light illuminance, intensity, color, incident direction, incident area, and distribution. The sensor can be an illuminance sensor, a temperature detection sensor, a light sensing layer, a camera, etc.

[0128] Specifically, the sensor can be implemented as an illuminance sensor that senses RGB light, but is not limited to this, and can be applied to any device capable of sensing light, such as a white sensor, an IR sensor, an IR+red sensor, an HRM sensor, a camera, etc.

[0129] In this scenario, several types of photovoltaic cells can be used for the illuminance sensor, but photovoltaic panels can also be used when measuring very low illuminance. For example, a CDS illuminance sensor can be mounted on the display device 100 and detect illuminance in two directions. In this case, the illuminance sensor can be mounted in at least one predetermined area on both surfaces of the display device 100, but it can also be mounted in each pixel unit on both surfaces. For example, the illuminance state of each area or each pixel can be measured by mounting an illuminance sensor, where the CMOS sensor has been magnified to correspond to the size of the mirror display 110. For example, the CDS illuminance sensor can detect the light around the display device 100, and an A / D converter can convert the voltage obtained by the CDS illuminance sensor into a digital value and send it to at least one processor 140.

[0130] At least one sensor can be provided, and if multiple sensors are provided, sensors can be applied at different locations if the location is one where illuminance can be measured in different directions. For example, a second sensor can be positioned based on sensing illumination in different directions, with angles differing from the first sensor by 90° or more.

[0131] As an example, the sensor can be arranged inside the glass disposed on the mirror display 110, and in this case, the display device 100 can control the sensor by an algorithm that compensates for the transmittance / reflectance of the glass disposed on the mirror display 110, so that the sensing function operates normally inside the glass. The display device 100 may also include various sensors required for the operation of the display device 100, such as touch sensors, accelerometers, geomagnetic sensors, user detection sensors, etc.

[0132] At least one processor 140 according to embodiments of the present disclosure can control the boundary of the first block 10 containing content A based on the amount of external light sensed by a sensor. Figure 8 The second reflectivity of at least one third block of 10⁻¹ (in the dashed line in the diagram) is 10⁻¹.

[0133] For example, such as Figure 9 As shown, when the intensity of light reflected by the mirror display 110 is high due to high external light illuminance, the visibility of content A deteriorates due to the reflected light. Furthermore, if the external light illuminance is high, the image quality of the image obtained by the camera 120 will be improved, thus potentially reducing the parallax perception between the remaining portion 2-2 of the mirror image 2 displayed by at least one third block 10-1 and the portion 2-1 of the mirror image 2 provided by a second block (excluding the first block 10) among the plurality of blocks.

[0134] According to an embodiment, if the amount of external light sensed by the sensor is greater than or equal to a threshold, at least one processor 140 can include the boundary of content A ( Figure 8 The second reflectivity of at least one third block 10-1 (in the dashed line in the diagram) is reduced to be adjacent to the third reflectivity (e.g., minimum reflectivity 0%).

[0135] For example, if the amount of external light sensed by the sensor is greater than or equal to a threshold, then at least one processor 140 can include the boundary of content A ( Figure 8 The second reflectivity of at least one third block 10-1 (with the dashed line in the figure) is controlled to be 30%.

[0136] According to an embodiment, the boundary including content A ( Figure 8 The parallax between the remaining portion 2-2 of mirror 2 shown by at least one third block 10-1 (with dashed lines in the image) and the portion 2-1 of mirror 2 obtained from an image of relatively good image quality is small, and includes the boundary of content A ( Figure 8 The second reflectivity of at least one third block 10-1 (in the dashed line) is reduced, thus improving the visibility of content A.

[0137] Figure 10 This is a diagram illustrating a display device according to an embodiment of the present disclosure that controls each of a first to a third reflectivity by sensing an amount of external light.

[0138] like Figure 10 As shown, when the intensity of light reflected by the mirror display 110 is low due to low external light illuminance (intensity of reflected light), the visibility of the content A displayed by the first block 10 becomes greater. Furthermore, if the external light illuminance is low, the image quality of the image obtained by the camera 120 will decrease (because the image obtained by the camera 120 includes noise), thus increasing the perceived parallax between the remaining portion 2-2 of the mirror image 2 displayed by at least one third block 10-1 and the portion 2-1 of the mirror image 2 provided by a second block among the plurality of blocks other than the first block 10.

[0139] According to an embodiment, if the amount of external light sensed by the sensor is less than a threshold, at least one processor 140 can include the boundary of content A ( Figure 8 The second reflectivity of at least one third block 10-1 (in the dashed line in the diagram) increases to be adjacent to the first reflectivity (e.g., the maximum reflectivity 100%).

[0140] For example, if the amount of external light sensed by the sensor is less than a threshold, at least one processor 140 can include the boundary of content A ( Figure 8 The second reflectivity of at least one third block 10-1 (with the dashed line in the figure) is controlled to be 70%.

[0141] According to an embodiment, at least one processor 140 can increase the boundary including content A ( Figure 8 The second reflectivity of at least one third block 10-1 (in the dashed line) reflects object 1 through at least one third block 10-1, thereby providing mirror 2 while providing content A.

[0142] The specific values ​​for the first to third reflectances mentioned above are merely examples for ease of explanation, and the values ​​may vary depending on the manufacturer's or user's settings.

[0143] Figure 11 This is a diagram illustrating a display device that provides visual effects according to embodiments of the present disclosure.

[0144] At least one processor 140 according to embodiments of the present disclosure can provide a visual effect of adjusting the size of content A.

[0145] For example, such as Figure 11 As shown on the left, at least one processor 140 can display content A through the first block 10 of a plurality of blocks 110-1, ..., 110-n. Furthermore, the second block of the plurality of blocks 110-1, ..., 110-n can provide a portion 2-1 of a mirror image 2 corresponding to object 1.

[0146] According to an embodiment, at least one third block 10-1, which includes the boundary of content A within the first block 10, can display the remaining portion 2-2 of mirror 2.

[0147] like Figure 11 As shown in the middle, at least one processor 140 can adjust the size of content A such that the boundaries of content A correspond to the boundaries between a plurality of blocks 110-1, ..., 110-n.

[0148] For example, such as Figure 11 As shown on the right, at least one processor 140 can increase the size of content A such that the boundary of content A lies on the boundary between at least one third block 10-1 and the block adjacent to at least one third block 10-1.

[0149] At least one processor 140 can provide a visual effect of gradually increasing the size of content A, such that the boundary of content A included in at least one third block 10-1 lies on the boundary between at least one third block 10-1 and the block adjacent to at least one third block 10-1 during a predetermined time period (or, during a predetermined frame period). According to embodiments, the predetermined time, the number of predetermined frames, etc., can be varied according to the manufacturer, user settings, etc.

[0150] However, this is merely an example, and at least one processor 140 can automatically increase content A such that the boundary of content A lies on the boundary between multiple blocks 110-1, ..., 110-n, or increase content A based on user input (e.g., extended input to increase the size of content A).

[0151] For ease of explanation, Figure 11 The image shows an increase in content A, but this is just an example and can provide the visual effect of gradually decreasing the size of content A.

[0152] For example, at least one processor 140 can provide a visual effect of gradually reducing the size of content A, such that the boundary of content A included in at least one third block 10-1 lies on the boundary between at least one third block 10-1 and the remaining blocks 10-2 of the first block 10, excluding at least one third block 10-1, during a predetermined time period (or, during a predetermined frame). According to an embodiment, at least one processor 140 can automatically reduce content A such that the boundary of content A lies on the boundary between a plurality of blocks 110-1, ..., 110-n, or reduce content A based on user input (e.g., a pinch input to reduce the size of content A).

[0153] return Figure 7 According to embodiments of the present disclosure, at least one processor 140 can blur (i.e., combine) at least one of the contents A displayed by at least one third block 10-1 or the remainder 2-2 of mirror 2 and display it.

[0154] Furthermore, at least one processor 140 can control at least one third block 10-1 to display a predetermined image in the remaining area of ​​at least one third block 10-1, excluding the area in the first block 10 where the content A is displayed that includes the boundary of the content A (i.e., where at least one third block 10-1 does not provide blank space for the content A or the mirror image 2). Here, the predetermined image may include a predetermined monochrome image, a predetermined pattern image, or an image pre-stored in the memory 130, etc.

[0155] return Figure 2 According to an embodiment of the present disclosure, at least one processor 140 can obtain the remainder 2-2 of the image 2, which continues from the portion 2-1 of the image 2 provided by a second block other than the first block 10 that provides content A, and can be provided by the first block 10 by inputting an image obtained by the camera 120 into a neural network model.

[0156] Here, the neural network model can be trained to recognize the user's viewpoint on the mirror display 110 via the camera 120, and convert the image obtained by the camera 120 into a model corresponding to the mirror surface reflected by the mirror display 110 based on the user's viewpoint.

[0157] The artificial intelligence-related functions according to this disclosure can be operated by at least one processor 140 and memory 130 of the display device 100.

[0158] At least one processor 140 may include at least one of a central processing unit (CPU), a graphics processing unit (GPU), or a neural processing unit (NPU), but is not limited to the processors described above.

[0159] A CPU is a general-purpose processor capable of performing not only ordinary operations but also artificial intelligence operations, and it can efficiently execute complex programs through a multi-layered cache structure. A CPU can be implemented for serial processing methods, which enable systematic linking between the results of previous and next computations through sequential computation. General-purpose processors are not limited to the examples above, excluding cases designated as the aforementioned CPU.

[0160] A GPU is a processor used for massive computations, such as floating-point operations for graphics processing, and it can perform massive computations in parallel through large-scale integration of cores. Specifically, compared to a CPU, a GPU can be implemented for parallel processing methods such as convolution operations. Furthermore, a GPU can be used as a coprocessor to supplement the functionality of a CPU. Processors used for large-scale operations are not limited to the examples above, excluding cases specifically designated as GPUs.

[0161] An NPU is a processor specifically designed for artificial intelligence operations using artificial neural networks, and it can implement each layer that makes up the artificial neural network as hardware (e.g., silicon). Here, the NPU is designed to specialize according to the specifications required by the company, and therefore may have less freedom compared to a CPU or GPU, but it can efficiently handle the artificial intelligence computations required by the company. As a processor dedicated to artificial intelligence computation, an NPU can be implemented in various forms, such as a Tensor Processing Unit (TPU), an Intelligent Processing Unit (IPU), a Visual Processing Unit (VPU), etc. Artificial intelligence processors are not limited to the examples mentioned above, except for those specifically designated as NPUs.

[0162] Furthermore, at least one processor 140 can be implemented as a system-on-a-chip (SoC). Here, in addition to one or more processors, the SoC may also include memory and network interfaces such as buses for data communication between the processor and memory.

[0163] In cases where the System-on-Chip (SoC) included in the display device 100 comprises multiple processors, the display device 100 can perform AI-related operations (e.g., operations related to learning or inference of AI models) by using some of the multiple processors. For example, the display device 100 can perform AI-related operations by using at least one of the multiple processors, such as a GPU, NPU, VPU, TPU, or a hardware accelerator dedicated to AI operations (such as convolution operations, matrix multiplication operations, etc.). However, this is only an example, and the display device 100 can also handle AI-related operations using a general-purpose processor such as a CPU.

[0164] Furthermore, the display device 100 can perform artificial intelligence-related operations by using multiple cores (e.g., dual-core, quad-core, etc.) included in a processor. Specifically, the display device 100 can perform artificial intelligence operations such as convolution operations and matrix multiplication operations in parallel by using the multiple cores included in the processor.

[0165] One or more processors perform control to process input data according to predefined operating rules or an artificial intelligence model stored in memory 130. The predefined operating rules or artificial intelligence model are characterized in that they are formed through learning.

[0166] Here, "learning" means applying a learning algorithm to multiple learning datasets to establish predefined operating rules or an artificial intelligence model with desired characteristics. This learning can be performed within the apparatus itself that performs artificial intelligence according to this disclosure, or via a separate server / system.

[0167] Artificial intelligence models may include multiple neural network layers. At least one layer has at least one weight value and performs operations on that layer using the results of operations from the previous layer and at least one defined operation. Examples of neural networks include convolutional neural networks (CNNs), deep neural networks (DNNs), recurrent neural networks (RNNs), restricted Boltzmann machines (RBMs), deep belief networks (DBNs), bidirectional recurrent deep neural networks (BRDNNs), generative adversarial networks (GANs), NeRF, deep Q-networks, and transformers; however, the neural networks in this disclosure are not limited to the examples mentioned above, excluding specific cases.

[0168] A learning algorithm is a method of training a specific object device (e.g., a robot) using multiple training data sets, thereby enabling the specific object device to make decisions or predictions on its own. As examples of learning algorithms, there are supervised learning, unsupervised learning, semi-supervised learning, or reinforcement learning, but the learning algorithms in this disclosure are not limited to the foregoing examples excluding specific cases.

[0169] The display device 100 according to embodiments of the present disclosure may further include a communication interface. According to implementation examples of the display device 100, the communication interface can be implemented as various interfaces. For example, the communication interface can perform communication with external devices, external storage media (e.g., USB memory), external servers (e.g., webhards) through communication methods such as Bluetooth, AP-based Wi-Fi (Wi-Fi, wireless LAN network), Zigbee, wired / wireless local area network (LAN), wide area network (WAN), Ethernet, IEEE 1394, high-definition multimedia interface (HDMI), universal serial bus (USB), mobile high-definition link (MHL), Audio Engineering Society / European Broadcasting Union (AES / EBU), optical, coaxial, etc. According to embodiments, the communication interface can perform communication with another electronic device, external server, and / or remote control device, etc.
