[0044] A battery (189) may power at least one component of the electronic device (101). In one embodiment, the battery (189) may include, for example, a non-rechargeable primary battery, a rechargeable secondary battery, or a fuel cell.

[0045] The communication module (190) may support the establishment of a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device (101) and an external electronic device (e.g., electronic device (102), electronic device (104), or server (108)), and the performance of communication through the established communication channel. The communication module (190) may operate independently from the processor (120) (e.g., application processor) and may include one or more communication processors that support direct (e.g., wired) communication or wireless communication. According to one embodiment, the communication module (190) may include a wireless communication module (192) (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module (194) (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication module can communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0046] The wireless communication module (192) can support 5G networks and next-generation communication technologies following the 4G network, such as NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), minimization of terminal power and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) can support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna. The wireless communication module (192) can support various requirements specified in the electronic device (101), an external electronic device (e.g., the electronic device (104)), or a network system (e.g., the second network (199)). According to one embodiment, the wireless communication module (192) can support a peak data rate (e.g., 20 Gbps or more) for eMBB realization, a loss coverage (e.g., 164 dB or less) for mMTC realization, or a U-plane latency (e.g., 0.5 ms or less for downlink (DL) and uplink (UL), or 1 ms or less for round trip) for URLLC realization.

[0047] The antenna module (197) can transmit or receive signals or power to or from an external device (e.g., an external electronic device). In one embodiment, the antenna module (197) may include an antenna including a radiator formed of a conductor or a conductive pattern formed on a substrate (e.g., a PCB). In one embodiment, the antenna module (197) may include a plurality of antennas (e.g., an array antenna). In this case, at least one antenna suitable for a communication method used in a communication network, such as the first network (198) or the second network (199), may be selected from the plurality of antennas, for example, by the communication module (190). A signal or power may be transmitted or received between the communication module (190) and an external electronic device via the at least one selected antenna. In some embodiments, in addition to the radiator, another component (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as a part of the antenna module (197).

[0048] In one embodiment, the antenna module (197) may form a mmWave antenna module. In one embodiment, the mmWave antenna module may include a printed circuit board, an RFIC disposed on or adjacent a first side (e.g., a bottom side) of the printed circuit board and capable of supporting a designated high-frequency band (e.g., a mmWave band), and a plurality of antennas (e.g., an array antenna) disposed on or adjacent a second side (e.g., a top side or a side side) of the printed circuit board and capable of transmitting or receiving signals in the designated high-frequency band.

[0049] At least some of the above components can be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, GPIO (general purpose input and output), SPI (serial peripheral interface), or MIPI (mobile industry processor interface)).

[0050] According to one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102 or 104) may be the same or a different type of device as the electronic device (101). According to one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of or in addition to executing the function or service itself, request one or more external electronic devices to perform the function or at least a part of the service. One or more external electronic devices that receive the request may execute at least a portion of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as is or additionally and provide it as at least a portion of a response to the request. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used, for example. The electronic device (101) may provide an ultra-low latency service by using distributed computing or mobile edge computing, for example. In another embodiment, the external electronic device (104) may include an Internet of Things (IoT) device. The server (108) may be an intelligent server utilizing machine learning and / or a neural network. According to one embodiment, the external electronic device (104) or the server (108) may be included in the second network (199).The electronic device (101) can be applied to intelligent services (e.g., smart home, smart city, smart car, or healthcare) based on 5G communication technology and IoT-related technology.

[0051] FIG. 2 is a drawing for explaining a three-dimensional display according to one embodiment.

[0052] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) may provide a 3D object (e.g., a 3D image) through one or more displays. Hereinafter, the 3D object may be referred to as a 3D image. The electronic device (101) may display the 3D image with a sense of perspective or depth as if it were actually present in space. Hereinafter, such a method of providing a 3D image may be referred to as a 3D display.

[0053] A display for providing a 3D image can include various types of structures, such as special lenses (e.g., lenticular lenses) or shields (e.g., parallax barriers) laminated on the display, which generate left-eye images and right-eye images, and allow the user's left and right eyes to perceive different images, thereby implementing a stereoscopic image based on binocular parallax, thereby providing the user with a 3D image. This 3D display implementation method can be divided into a glasses method and a glasses-free method. The glasses method can include, for example, a color filter method, a polarizing filter method, and a shutter glass method, and the glasses-free method can include a lenticular lens method and a parallax barrier method. In particular, the glasses-free method utilizes the principle that the brain recognizes the difference in images entering the left and right eyes as three-dimensional. These 3D display implementation methods are known technologies, so a detailed description thereof will be omitted.

[0054] In a 3D display, an object may be a component of a displayed 3D image, or a graphic element for interfacing with a user. An object may represent, for example, content, a program (application), or a specific function of an application, and may include various images that may or may not perform a function, such as icons, emoticons, emojis, menus, lists, folders, and thumbnails. An object may be composed of a left object, which is viewed by the user's left eye, and a right object, which is viewed by the user's right eye.

[0055] 3D displays can be implemented through disparity, the distance between the left and right objects. Parallax can be broadly categorized into crossed disparity, zero disparity, and uncrossed disparity. Specifically, crossed disparity refers to the parallax that makes the image appear to be located in front of a reference plane. Uncrossed disparity refers to the parallax that makes the image of an object appear to be located behind the reference plane. Zero disparity refers to the parallax that makes the image of an object appear to be located on the reference plane. Here, the reference plane can be a virtual plane between the display screen and the user, or it can be the display screen itself.

[0056] If an object's parallax value corresponds to zero parallax, the user will perceive the object as being on the screen. If the object's parallax value corresponds to cross parallax, the user will perceive the object as being in front of the screen. If the object's parallax value corresponds to non-cross parallax, the user will perceive the object as being behind the screen.

[0057] According to one embodiment, the electronic device (101) can adjust the depth of an object by adjusting the disparity between the left object and the right object. Here, the depth may mean the distance in the Z-axis direction when the reference plane is referred to as the XY plane, and may also be referred to as the protrusion distance hereinafter. For example, if the object is located on the reference plane, the depth or protrusion distance will have a value of '0', if the object is located in front of the reference plane, the depth or protrusion distance will have a positive value, and if the object is located behind the reference plane, the depth or protrusion distance will have a negative value.

[0058] According to one embodiment, the protrusion distance (P) can be calculated based on the viewing distance (V), which is the distance between the user and the display, the disparity (D) between the images perceived by the left and right eyes, and the interpuplilary distance (IPD) between the two eyes. For example, the protrusion distance (P) can be calculated based on the following mathematical expression 1.

[0059] [Mathematical Formula 1]

[0060] P = (V x D) / (IPD + D)

[0061] The distance difference value (D, disparity) can be expressed in pixels, and the distance between the two eyes (IPD, interpuplilary distance) can generally be 62 to 65 mm.

[0062] FIG. 3 is a diagram illustrating various electronic devices according to one embodiment.

[0063] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) may include various devices such as a mobile phone, a smart phone, a foldable phone, a foldable device with dual displays, a tablet PC, a hand-held PC, a portable multimedia player (PMP), and a personal digital assistant (PDA), which have a three-dimensional image display function, that is, a function of displaying an image with a sense of perspective or depth as if it were actually in space. In addition, the electronic device (101) according to one embodiment may include a device including two or more displays, such as a multi-device including two tablet PCs, or two or more independent display devices. In the following description, a foldable phone is used as an example, but the embodiments are not limited thereto.

[0064] FIG. 4 is a drawing showing an example of an electronic device according to one embodiment.

[0065] An electronic device (101) according to one embodiment may include a display (e.g., a display module (160) of FIG. 1) including a first display area (401) and a second display area (402). The first display area (401) and the second display area (402) may be implemented as one or two display structures that are connected to each other, or may be implemented as separate display structures that are spaced apart or separated from each other. For example, the electronic device (101) may be implemented as a foldable phone in which the first display area (401) and the second display area (402) can be folded or unfolded based on their boundaries. For example, the electronic device (101) may include two or more electronic devices, including a first electronic device including a first display area (401) and a second electronic device including a second display area (402).

[0066] The first display area (401) may be a display area capable of three-dimensional stereoscopic expression. For example, a lenticular lens or a parallax barrier may be attached to the first display area (401).

[0067] The second display area (402) may be an area capable of two-dimensional display. The second display area (402) may be a display area capable of two-dimensional display and three-dimensional display may be implemented in an on or off manner.

[0068] The first display area (401) and / or the second display area (402) may include, for example, a display, a three-dimensional display, a holographic device, or a projector and a control circuit for controlling the device. The first display area (401) and / or the second display area (402) may include a touch sensor (e.g., a touch screen) configured to detect a touch, and / or a pressure sensor configured to measure the intensity of a force generated by the touch. The touch sensor may include a touch screen to which various technologies such as a resistive type, a capacitive type, an electromagnetic induction type, and a pressure type are applied.

[0069] An electronic device (101) according to one embodiment may include a sensor (403) (e.g., a sensor module (176) of FIG. 1 ). The sensor (403) may include, for example, an eye tracking sensor (e.g., a camera) for recognizing the position of a user's left eye and / or right eye. The sensor (403) may include an RGB sensor and / or a depth sensor.

[0070] The first display area (401) and / or the second display area (402) including a touch sensor and / or a pressure sensor can generate a touch event according to a user's touch gesture on the display area and transmit the generated touch event to a processor (e.g., the processor (120) of FIG. 1). The processor can detect the user's touch gesture based on the touch event input through the display area and perform a corresponding operation. For example, the processor can change the properties of a display image (e.g., a three-dimensional image or an object) of the first display area (401) based on the touch event input through the second display area (402). Changing the properties of the display image may include, for example, color correction (e.g., brightness, contrast, saturation), various image effects (e.g., flipping, cropping, distorting, compositing, applying filters), changing to multiple sub-images (e.g., continuous motion of characters and objects, morphing, transformation, texture change), and / or displaying and / or executing various information embedded in the display image (e.g., specific functions, crawling data, metadata, blockchain data), in addition to changing the size and / or display orientation of the display image.

[0071] Meanwhile, the properties of a two-dimensional image can also change in response to changes in the properties of a three-dimensional image. Touch gestures may include Touch, Tap, Double Tap, Press, Drag, Drag&Drop, and Sweep. Here, Touch refers to an operation in which a user presses a certain point on the screen, Tap refers to an operation in which a finger is lifted from a certain point without moving the finger after touching the point, i.e., a drop operation, Double Tap refers to an operation in which a certain point is tapped twice consecutively, Press refers to an operation in which a finger is lifted from a certain point without moving the finger, Drag refers to an operation in which a finger is moved in a specific direction while touching a certain point, Drag&Drop refers to an operation in which a finger is dragged and then lifted, and Sweep refers to an operation in which a finger is moved at a high speed and then lifted, as if bouncing. Here, Drag is also called Scroll, and Sweep is also called Flick. The processor can distinguish between Sweep and Drag based on the movement speed.

[0072] FIG. 5 is a drawing for explaining the operation of an electronic device according to one embodiment.

[0073] The electronic device of FIG. 5 (e.g., the electronic device (101) of FIG. 1 or FIG. 4) may include a display (e.g., the display module (160) of FIG. 1) including a first display area (401) and a second display area (402). The first display area (401) and the second display area (402) may be implemented as one or two display structures that are connected to each other, or may be implemented as separate display structures that are spaced apart or separated from each other. For example, the electronic device (101) may be implemented as a foldable phone in which the first display area (401) and the second display area (402) can be folded or unfolded based on their boundaries. For example, the electronic device (101) may include two or more electronic devices, including a first electronic device including a first display area (401) and a second electronic device including a second display area (402). The description below with reference to FIG. 4 may be omitted to avoid duplication.

[0074] Referring to FIG. 5, a processor (e.g., processor (120) of FIG. 1) can display a three-dimensional image (501) through a first display area (401).

[0075] According to one embodiment, the processor may determine a protrusion distance (e.g., the protrusion distance (P) described with reference to FIG. 2) of a three-dimensional image (501) from the first display area (401), and render and display a two-dimensional image corresponding to the three-dimensional image at a location (e.g., location (517 or 518)) of the second display area (402) corresponding to the protrusion distance (P) of the three-dimensional image (501). For example, the location corresponding to the protrusion distance (P) may be a location (517) spaced apart from the boundary with the first display area (401) by the protrusion distance (P) on the second display area (402). For example, the location corresponding to the protrusion distance (P) may be a location (518) vertically projected from the location of the protrusion distance (P) of the three-dimensional image displayed through the first display area (401) on the second display area (402).

[0076] According to one embodiment, the position corresponding to the protrusion distance (P) may be a position (507) determined based on the position of the 3D image and the user's gaze position (e.g., 503). The processor may determine the user's gaze position (503). For example, the user's gaze position (503) may be a position determined by a sensor (e.g., sensor (403) of FIG. 4), for example, a position tracked by eye tracking. For example, the user's gaze position (503) may be an arbitrary position estimated by the processor. For example, the user's gaze position may be estimated as an arbitrary position, such as a position moved vertically from a certain point (e.g., the center point or the center point of the upper edge) of the screen of the first display area (401) by a specified distance (e.g., the end point of the second display area (402).

[0077] The processor can set a virtual camera position (505) corresponding to the user's eye position (503) based on the user's gaze position (503) with respect to the second display area (402). The position of the virtual camera (505) may be a position (505) symmetrical to the user's gaze position (503) with respect to the second display area (402). The position of the virtual camera (503)

[0078] For example, a line connecting the position of the virtual camera (505) and the user's gaze position (503) may be perpendicular to the plane of the second display area (402), and the distance from the position of the virtual camera (505) and the user's gaze position (503) to the second display area (402) may be the same. The processor may project and display a two-dimensional image corresponding to the three-dimensional image (501) at a position (609) of the second display area (402) corresponding to the position of the three-dimensional image (501) (a position spaced apart by the protrusion distance from the first display area (401)) at the position (505) of the virtual camera.

[0079] The position (507) of the second display area (402) where the two-dimensional image is displayed may be the position (507) where a virtual straight line drawn from the position (505) of the virtual camera to the position of the three-dimensional image (501) (a position spaced apart by the protrusion distance from the first display area (401)) intersects the second display area (402). The two-dimensional image displayed on the second display area (402) may be a reflection image projected onto the second display area (402) of an image viewed from the position (505) of the virtual camera at the three-dimensional image (501).

[0080] FIG. 6 is a drawing for explaining the operation of an electronic device according to one embodiment.

[0081] The electronic device of FIG. 6 (e.g., the electronic device (101) of FIG. 1 or FIG. 4) may include a display (e.g., the display module (160) of FIG. 1) including a first display area (401) and a second display area (402). The first display area (401) and the second display area (402) may be implemented as one or two display structures that are connected to each other, or may be implemented as separate display structures that are spaced apart or separated from each other. For example, the electronic device (101) may be implemented as a foldable phone in which the first display area (401) and the second display area (402) can be folded or unfolded based on their boundaries. For example, the electronic device (101) may include two or more electronic devices, including a first electronic device including a first display area (401) and a second electronic device including a second display area (402).

[0082] The first display area (401) may be a display area capable of three-dimensional stereoscopic expression. For example, a lenticular lens or a parallax barrier may be attached to the first display area (401). The second display area (402) may be a region capable of two-dimensional display. The second display area (402) may be a display area capable of two-dimensional display and three-dimensional display may be implemented in an on or off manner.

[0083] Referring to FIG. 6, a processor (e.g., processor (120) of FIG. 1) can display a three-dimensional image (601) through a first display area (401).

[0084] According to one embodiment, the processor may determine a protrusion distance (e.g., the protrusion distance (P) described with reference to FIG. 2) from the first display area (401) of the three-dimensional image (601), and render and display a two-dimensional image corresponding to the three-dimensional image at a location in the second display area (402) corresponding to the protrusion distance (P) of the three-dimensional image (601).

[0085] According to one embodiment, the position corresponding to the protrusion distance (P) may be a position (607) determined based on the position of the 3D image and the user's gaze position (e.g., 603). The processor may identify the user's gaze position (603). For example, the user's gaze position (603) may be a position identified by a sensor (e.g., sensor (403) of FIG. 4), for example, a position tracked by eye tracking. For example, the user's gaze position (603) may be a position arbitrarily estimated by the processor.

[0086] The processor can set a virtual camera position (605) corresponding to the user's eye position (603) with respect to the second display area (402) based on the user's gaze position (603). The position of the virtual camera (605) may be a position (605) symmetrical to the user's gaze position (603) with respect to the second display area (402). For example, a line connecting the position of the virtual camera (605) and the user's gaze position (603) may be perpendicular to the plane of the second display area (402), and the distance from the position of the virtual camera (605) and the user's gaze position (603) to the second display area (402) may be the same. The processor can project and display a two-dimensional image corresponding to the three-dimensional image (601) at a position (609) of the second display area (402) corresponding to the position of the three-dimensional image (601) (a position spaced apart from the first display area (401) by the protrusion distance) at the position (605) of the virtual camera. The position (607) of the second display area (402) where the two-dimensional image is displayed may be a position (607) where a virtual straight line drawn from the position (605) of the virtual camera to the position of the three-dimensional image (601) (a position spaced apart from the first display area (401) by the protrusion distance) intersects the second display area (402). The two-dimensional image displayed on the second display area (402) may be a reflection image projected onto the second display area (402) of an image viewed from the position (605) of the virtual camera at the three-dimensional image (601).

[0087] According to one embodiment, the position of the virtual camera (605) is synchronized with the user's gaze position (603), so that the X and Y axes move in the same direction and the Z axis moves in the opposite direction. Accordingly, the shape of the two-dimensional image displayed in the second display area (402) by reflecting the three-dimensional image can change according to the movement of the user's gaze (603).

[0088] FIG. 7 is a drawing for explaining the operation of an electronic device according to one embodiment.

[0089] The electronic device of FIG. 7 (e.g., the electronic device (101) of FIG. 1, FIG. 4, FIG. 5, or FIG. 6) may include a display (e.g., the display module (160) of FIG. 1) including a first display area (401) and a second display area (402). Any description that overlaps with the description made with reference to FIG. 1, FIG. 4, FIG. 5, or FIG. 6 will be omitted.

[0090] Referring to FIG. 7, a processor (e.g., processor (120) of FIG. 1) can display a three-dimensional image (701) through a first display area (401).

[0091] The processor can set a virtual camera position (705) corresponding to the user's eye position (703) with respect to the second display area (402) based on the user's gaze position (703). The position of the virtual camera (705) may be a position (705) symmetrical to the user's gaze position (703) with respect to the second display area (402). For example, a line connecting the position of the virtual camera (705) and the user's gaze position (703) may be perpendicular to the plane of the second display area (402), and the distance from the position of the virtual camera (705) and the user's gaze position (703) to the second display area (402) may be the same. The processor can project and display a two-dimensional image corresponding to the three-dimensional image (701) at a position (709) of the second display area (402) corresponding to the position of the three-dimensional image (701) (a position spaced apart by a protrusion distance from the first display area (401)) at a position (705) of the virtual camera.

[0092] According to one embodiment, the position of the virtual camera (705) is synchronized with the user's gaze position (703), so that the X and Y axes move in the same direction and the Z axis moves in the opposite direction. Accordingly, the shape of the two-dimensional image displayed in the second display area (402) by reflecting the three-dimensional image can change according to the movement of the user's gaze (703).

[0093] According to one embodiment, the position (701) of the three-dimensional image may be a variable that is independent of the angle and / or position of the screen of the first display area (401) and / or the second display area (402). For example, if the position at which the three-dimensional image is output does not change even if the angle of the first display area (401) changes, the image displayed on the second display area (402) may remain the same. For example, the reference point at which the two-dimensional image is displayed on the second display area (402) may be, for example, the height at which the three-dimensional image (701) floats from the second display area (402) and / or the angle formed by the first display area (401) and the second display area (402). For example, the two-dimensional image may be displayed at a point (707) at which the two-dimensional image (709) is reflected and appears by being symmetrical by a distance equal to the height at which the three-dimensional image (701) floats with respect to the second display area (402).

[0094] FIG. 8 is a drawing for explaining the operation of an electronic device according to one embodiment.

[0095] The electronic device of FIG. 8 (e.g., the electronic device (101) of FIG. 1, FIG. 4, FIG. 5, FIG. 6, or FIG. 7) may include a display (e.g., the display module (160) of FIG. 1) including a first display area (401) and a second display area (402). Any description overlapping with that described with reference to FIG. 1, FIG. 4, FIG. 5, FIG. 6, or FIG. 7 will be omitted.

[0096] Referring to FIG. 8, a processor (e.g., processor (120) of FIG. 1) can display a three-dimensional image (801) through a first display area (401).

[0097] The processor can set a virtual camera position (805) corresponding to the user's eye position (803) with respect to the second display area (402) based on the user's gaze position (803). The position of the virtual camera (805) may be a position (805) symmetrical to the user's gaze position (803) with respect to the second display area (402). For example, a line connecting the position of the virtual camera (805) and the user's gaze position (803) may be perpendicular to the plane of the second display area (402), and the distance from the position of the virtual camera (805) and the user's gaze position (803) to the second display area (402) may be the same.

[0098] The processor can determine that the position (807) of the second display area (402) corresponding to the position of the three-dimensional image (801) (a position spaced apart by a protrusion distance from the first display area (401)) at the position (805) of the virtual camera is outside the second display area (402). In this case, the processor can determine that the two-dimensional image cannot be displayed, and can cause the two-dimensional image (809) corresponding to the three-dimensional image (801) not to be displayed in the second display area (402) or to be displayed by changing its position.

[0099] FIG. 9 is a drawing for explaining the operation of an electronic device according to one embodiment.

[0100] The electronic device of FIG. 9 (e.g., the electronic device (101) of FIG. 1 or FIG. 4) may include a display (e.g., the display module (160) of FIG. 1) including a first display area (401) and a second display area (402). Any description overlapping with that described with reference to FIG. 1 or FIG. 4 will be omitted.

[0101] Referring to FIG. 9, a processor (e.g., processor (120) of FIG. 1) can display a three-dimensional image (901) through a first display area (401).

[0102] The processor can set a virtual camera position (905) corresponding to the user's eye position (903) based on the user's gaze position (903) with respect to the second display area (402). The position of the virtual camera (905) may be a position (905) symmetrical to the user's gaze position (903) with respect to the second display area (402). For example, a line connecting the position of the virtual camera (905) and the user's gaze position (903) may be perpendicular to the plane of the second display area (402), and the distance from the position of the virtual camera (905) and the user's gaze position (903) to the second display area (402) may be the same.

[0103] The processor can display a two-dimensional image at a position (907) of the second display area (402) corresponding to the position of the three-dimensional image (901) (a position spaced apart by a protrusion distance from the first display area (401)) at the position (905) of the virtual camera.

[0104] As illustrated in FIG. 9, the two-dimensional image displayed on the second display area (402) may be a reflection image projected onto the second display area (402) as an image viewing the three-dimensional image (901) from the position (905) of the virtual camera. Accordingly, when the display properties of the three-dimensional image (901) displayed through the first display area (401) are changed, such as rotation or change in display direction, the properties of the two-dimensional image (907), which is a reflection image projected onto the second display area (402), such as the display direction and / or shape, may also be changed correspondingly.

[0105] FIGS. 10, 11, 12, and 13 are drawings for explaining display control operations of an electronic device according to one embodiment.

[0106] The electronic devices of FIGS. 10, 11, 12, and 13 (e.g., the electronic device (101) of FIG. 1 or FIG. 4, FIG. 5, FIG. 6, FIG. 7, FIG. 8, or FIG. 9) may include a display (e.g., the display module (160) of FIG. 1) including a first display area (401) and a second display area (402). Any description that overlaps with the description made with reference to FIGS. 1, 4, 5, 6, 7, 8, or 9 will be omitted.

[0107] The first display area (401) may be a display area capable of three-dimensional stereoscopic expression. The second display area (402) may be an area capable of two-dimensional display.

[0108] The processor can display a two-dimensional image (1009) corresponding to a three-dimensional image (1001) provided through the first display area (401) in the second display area (402) as described above in various embodiments.

[0109] As illustrated in FIG. 10, the two-dimensional image (1007) displayed in the second display area (402) may be a reflection image in which an image of a specific direction of the three-dimensional image (1001) is projected onto the second display area (402).

[0110] The processor may change properties of a three-dimensional image (1001) provided through the first display area (401) in response to a user interaction related to a two-dimensional image (1007) displayed on the second display area (402). For example, the properties of the three-dimensional image (1001) may include the direction, position, size, and / or shape in which the three-dimensional image (1001) is displayed.

[0111] A user interaction related to a two-dimensional image (1007) may include a touch event input through a second display area (402). The processor may detect a touch gesture of a user (1011) (e.g., a hand or a stylus pen) based on the touch event and perform a corresponding action. For example, the processor may change a property of a display image (e.g., a three-dimensional image or object) of the first display area (401) based on a touch event input through a nearby area (1013) including a two-dimensional image (1009) displayed on the second display area (402).

[0112] Touch gestures may include various touch gestures performed based on Touch, Tap, Double Tap, Press, Drag, Drag&Drop, and Flick.

[0113] Referring to FIG. 11, a plurality of three-dimensional images (1101, 1102) may be displayed in a first display area (401). Accordingly, a plurality of two-dimensional images (1109, 1110) corresponding to each of the three-dimensional images (1101, 1102) may be displayed in a second display area (402). A user may perform a user interaction on one or more of the two-dimensional images (1109, 1110) (e.g., the two-dimensional image (1109)) using a hand (1111), and based on a touch event generated by a user input including a touch input according to the user interaction, a display property of a corresponding three-dimensional image (e.g., the three-dimensional image (1101)) among the three-dimensional images (1101, 1102) may be changed.

[0114] Referring to FIG. 12, touch gestures may include pinch out or pinch in (1201), flick (1202), panning (1203), two finger up or down (1204), swiping (1205) on a two-dimensional image (1200), and / or tapping (1206) on a point (1010) outside the two-dimensional image (1200), although embodiments are not limited thereto and various variations are possible.

[0115] According to one embodiment, the size of a three-dimensional image displayed on the first display area (401) may be enlarged or reduced in response to a pinch out or pinch in (1201) on the second display area (401), the display direction of the three-dimensional image may be rotated in response to a flick (1202), the position of the three-dimensional image may be moved on the XY plane in response to a pan (1203), or the three-dimensional image may be moved (e.g., depth may be increased or decreased) on the Z axis in response to a two-finger up or down (1204). According to one embodiment, the three-dimensional image (1200) of the second display area (401) may be rotated by a swipe (1205) on the three-dimensional image (1200), or the three-dimensional image may be moved in the tap direction by a tap (1206) on a point (1010) outside the two-dimensional image (1200). The embodiments are not limited thereto and various modifications are possible.

[0116] Referring to FIG. 13, in (a), a touch input (e.g., drag) to a two-dimensional image (1302) corresponding to a three-dimensional image (1301) can cause the three-dimensional image (1301) to move in the direction of the touch input. In (b), a touch input (e.g., two fingers down) to a two-dimensional image (1312) corresponding to the three-dimensional image (1311) can cause the three-dimensional image (1311) to move in the positive Z-axis direction (e.g., toward the front of the screen). In (c), a touch input (e.g., swipe) to a two-dimensional image (1322) corresponding to the three-dimensional image (1321) can cause the three-dimensional image (1321) to rotate in the direction of the touch input.

[0117] FIG. 14 and FIG. 15 are drawings for explaining the display operation of an electronic device according to one embodiment.

[0118] The electronic device of FIG. 14 or FIG. 15 (e.g., the electronic device (101) of FIG. 1 or FIG. 4) may include a display (e.g., the display module (160) of FIG. 1) including a first display area (401) and a second display area (402). Any description overlapping with that described with reference to FIG. 1 or FIG. 4 will be omitted.

[0119] According to one embodiment, in the example of (a), depending on the protrusion distance of the three-dimensional image (1401) provided through the first display area (401), a corresponding two-dimensional image (1407) displayed on the second display area (402) may be partially or not displayed. In this case, despite the protrusion distance of the three-dimensional image (1411) provided through the first display area (401), the two-dimensional image (1407) may be substantially displayed in its entirety by distorting and / or changing the display position of the corresponding two-dimensional image (1417) displayed on the second display area (402), as in the example of (b).

[0120] Referring to FIG. 15, in the example of (a), depending on the protrusion distance of the three-dimensional image (1501) provided through the first display area (401), the corresponding two-dimensional image (1407) displayed on the second display area (402) may be partially displayed or not displayed.

[0121] In this case, in order to display the two-dimensional image substantially entirely, the two-dimensional image (1517) may be rendered by changing the angle of the second display area (402) into a virtual screen, as in the example of (b). Alternatively, the position of the two-dimensional image (1527) may be moved and displayed, as in the example of (c).

[0122] Accordingly, user interaction with two-dimensional images displayed in the second display area (402) can be performed more easily.

[0123] FIG. 16 is a drawing showing an example of an electronic device according to one embodiment.

[0124] An electronic device according to one embodiment (e.g., electronic device (101) of FIG. 1 or FIG. 4) may include a display (e.g., display module (160) of FIG. 1) including a first display area (401) and a second display area (402).

[0125] As illustrated in FIG. 16 (a), the first display area (401) and the second display area (402) may be implemented as separate display structures that are spaced apart or separated from each other. For example, the electronic device (101) may include two or more electronic devices, including a first electronic device (101-1) (e.g., a tablet) including a first display area (401) and a second electronic device (101-2) (e.g., a smartphone) including a second display area (402).

[0126] The first display area (401) may include a display capable of three-dimensional stereoscopic expression. For example, a lenticular lens or a parallax barrier may be attached to the first display area (401).

[0127] The second display area (402) may include a display capable of two-dimensional display. The second display area (402) may include a display capable of two-dimensional display and a three-dimensional display that can be implemented in an on or off manner.

[0128] Various data required for display can be transmitted and received through communication between the first electronic device (101-1) and the second electronic device (101-2).

[0129] For example, the first electronic device (101-1) can transmit data for a three-dimensional image (1601) provided through the first display area (401) of the display device as described above to the second electronic device (101-2), so that the second electronic device (101-2) can display a two-dimensional image (1607) on the second display area (402). The data for the three-dimensional image (1601) can include various image information such as display direction, shape, color, and position. For example, when the second electronic device (101-2) moves near the first electronic device (101-1) and approaches a range in which a two-dimensional image corresponding to the three-dimensional image (1607) provided through the first electronic device (101-1) can be displayed, for example, a two-dimensional image displayable range according to a protrusion distance, the two-dimensional image (1607) can be displayed on the second display area (402).

[0130] As illustrated in FIG. 16 (b), the properties of the three-dimensional image (1601) displayed through the first display area (401) can be changed in response to a touch event on the two-dimensional image (1607) displayed on the second display area (402) and / or movement of the display area (402) itself.

[0131] According to one embodiment, the second electronic device (101-2) may transmit data regarding a user interaction related to a two-dimensional image (1607) displayed on the second display area (402) to the first electronic device (101-2), so as to change properties of a three-dimensional image (1601) provided through the first display area (401) according to the user interaction. For example, the properties of the three-dimensional image (100) may include the direction, position, size, and / or shape in which the three-dimensional image (1001) is displayed.

[0132] According to one embodiment, a touch event may include various touch inputs as described above, and may also include a touch input by a gesture, for example, an air gesture. When the second electronic device (101-2) is moved while touching a two-dimensional image (1607) output to the second electronic device (101-2) or its vicinity, the three-dimensional image (1601) displayed on the first electronic device (101) may be moved in the direction in which the second electronic device (101-1) moves.

[0133] FIG. 17 is a drawing for explaining the operation of an electronic device according to one embodiment.

[0134] The electronic device of FIG. 17 (e.g., the electronic device (101) of FIG. 1 or FIG. 4) may include a display (e.g., the display module (160) of FIG. 1) including a first display area (401) and a second display area (402). Any description overlapping with that described with reference to FIG. 1 or FIG. 4 will be omitted.

[0135] Referring to FIG. 17, a processor (e.g., processor (120) of FIG. 1) can display a three-dimensional image (1701) through a first display area (401).

[0136] The processor can display a two-dimensional image (1709) at a position (1707) corresponding to a projection distance of the three-dimensional image (1701) regardless of the user's gaze position (1703). For example, the virtual camera position (1705) can be set at the lower or upper surface of the three-dimensional image (1701). For example, a two-dimensional image (1709) corresponding to a position where the three-dimensional image (1701) is vertically projected to the second display area (402) at the position of the virtual camera (1705) can be displayed.

[0137] The processor can display a two-dimensional image (1709) at a location (1707) of a second display area (402) corresponding to the location of the three-dimensional image (1701) (a location spaced apart by a protrusion distance from the first display area (401)) at a location (1705) of the virtual camera.

[0138] As illustrated in FIG. 17, the two-dimensional image displayed in the second display area (402) may include an image generated according to the properties of the three-dimensional image (1701). For example, when the weather widget is executed, if the three-dimensional image (1701) is a cloud, the generated two-dimensional image (1709) may be an image of rain falling on the ground.

[0139] FIG. 18 is a drawing for explaining the operation of an electronic device according to one embodiment.

[0140] The electronic device of FIG. 18 (e.g., the electronic device (101) of FIG. 1 or FIG. 4) may include a display (e.g., the display module (160) of FIG. 1) including a first display area (401) and a second display area (402).

[0141] The first display area (401) may be a display area capable of three-dimensional stereoscopic expression. The first display area (401) may also be capable of two-dimensional image expression. The second display area (402) may be a area capable of two-dimensional display. The second display area (402) may be a display area capable of two-dimensional display and three-dimensional display may be implemented in an on or off manner.

[0142] Referring to FIG. 18, a processor (e.g., processor (120) of FIG. 1) can display a three-dimensional image (1801) through a second display area (402).

[0143] According to one embodiment, the processor may determine a display position of a three-dimensional image (1801), for example, a distance from a first display area (401) (e.g., a protrusion distance (P) described with reference to FIG. 2), and render and display a two-dimensional image corresponding to the three-dimensional image at a position (1807) of the first display area (401) corresponding to the display position of the three-dimensional image (1801).

[0144] According to one embodiment, the display position (1807) of the two-dimensional image in the first display area (401) may be a position (1807) determined based on the position of the three-dimensional image and the user's gaze position (e.g., 1803). The processor may determine the user's gaze position (1803). For example, the user's gaze position (1803) may be an arbitrarily estimated position. For example, the user's gaze position (1803) may be a position determined by a sensor (e.g., the sensor (403) of FIG. 4), for example, a position tracked by eye tracking.

[0145] The processor can set a virtual camera position (1805) corresponding to the user's eye position (1803) with respect to the first display area (401) based on the user's gaze position (1803). The position of the virtual camera (1805) may be a position (1805) symmetrical to the user's gaze position (1803) with respect to the first display area (401). For example, a line connecting the position of the virtual camera (1805) and the user's gaze position (1803) may be perpendicular to the plane of the first display area (401), and the distance from the first display area (401) to the position of the virtual camera (1805) and the user's gaze position (1803) may be the same.

[0146] The processor can project and display a two-dimensional image (1809) corresponding to the three-dimensional image (1801) at a position (1807) of the first display area (402) corresponding to the position of the three-dimensional image (1801) at the position (1805) of the virtual camera. The position (1807) of the first display area (401) where the two-dimensional image is displayed may be a position (1807) where a virtual straight line extending from the position (1805) of the virtual camera to the position of the three-dimensional image (1801) intersects the first display area (401). The two-dimensional image displayed on the first display area (401) may be a reflection image projected onto the first display area (401) of an image viewed from the position (1805) of the virtual camera at the three-dimensional image (1801).

[0147] Accordingly, various information including the shape of the rear portion of the three-dimensional image displayed in the second display area (402) can be displayed in the first display area (401). Accordingly, in addition to the three-dimensional image, various information regarding the rear portion of the three-dimensional image that cannot be sufficiently displayed even with the three-dimensional image can be displayed through the two display areas.

[0148] FIG. 19 is a drawing for explaining the operation of an electronic device according to one embodiment.

[0149] The electronic device of FIG. 19 (e.g., the electronic device (101) of FIG. 1 or FIG. 4) may include a display (e.g., the display module (160) of FIG. 1) including a first display area (401) and a second display area (402).

[0150] The first display area (401) may be a display area capable of three-dimensional stereoscopic expression. The second display area (402) may be an area capable of two-dimensional display.

[0151] Referring to FIG. 19, a processor (e.g., processor (120) of FIG. 1) can display a three-dimensional image (1901) through a first display area (401).

[0152] According to one embodiment, the processor may determine a display position of a three-dimensional image (1901), for example, a distance from a first display area (401) (e.g., a protrusion distance (P) described with reference to FIG. 2), and render and display a two-dimensional image corresponding to the three-dimensional image at a position (1907) of a second display area (402) corresponding to the display position of the three-dimensional image (1901).

[0153] According to one embodiment, a first display area (401) where a two-dimensional image is displayed may display various image objects including selectable objects including images, keys, or buttons including emoticons.

[0154] According to one embodiment, the legibility of a two-dimensional image displayed on the second display area (402) may vary depending on the brightness, contrast, and / or color of the screen of the second display area (402). For example, if the second display area (402) is a black surface, external light may be absorbed, and self-reflected light may not be substantially emitted, thereby increasing the legibility of the displayed two-dimensional image.

[0155] According to one embodiment, the processor can adjust the density of the displayed two-dimensional image (1907) based on the brightness, luminance, and / or color of the second display area (402). For example, the higher the brightness and / or luminance of the second display area (402), the more blurred the rendering density of the two-dimensional image (1907) can be output. For example, the closer the color of the second display area (402) is to a dark color or black, the more the rendering density of the two-dimensional image (1907) can be adjusted to be visible.

[0156] Meanwhile, the illuminance or brightness of the external environment can be measured using an illuminance sensor (e.g., the sensor module (176) of FIG. 1), and the rendering density of a two-dimensional image can be adjusted according to the illuminance. For example, when the illuminance is high, the rendering density of a two-dimensional image can be adjusted to be blurred, and when the illuminance is low, the rendering density of a two-dimensional image can be adjusted to be high.

[0157] Figure 20 is a flowchart for explaining the operation of an electronic device according to one embodiment.

[0158] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1, FIG. 4, and / or FIG. 5) may include a display (e.g., the display module (160) of FIG. 1) that includes a first display area (401) and a second display area (402).

[0159] Referring to FIG. 20, a processor (e.g., processor (120) of FIG. 1) can display a three-dimensional image (e.g., three-dimensional image (501) of FIG. 5) through a first display area (401) in operation 2001.

[0160] According to one embodiment, the processor may determine, at operation 2003, a protrusion distance (e.g., a protrusion distance (P) described with reference to FIG. 2) of a three-dimensional image (501) from a first display area (401). The display position of the three-dimensional image (501) may include, for example, a distance (e.g., a protrusion distance (P) described with reference to FIG. 2) from the first display area (401).

[0161] According to one embodiment, the processor may display a two-dimensional image corresponding to the three-dimensional image on the second display area (402) based on the protrusion distance of the three-dimensional image (501) in operation 2005. The display position of the two-dimensional image based on the protrusion distance may be a position (e.g., position (517) of FIG. 5) spaced apart from the boundary with the first display area (401) by the protrusion distance on the second display area (402). For example, the position corresponding to the protrusion distance may be a position vertically projected from the position of the protrusion distance of the three-dimensional image displayed through the first display area (401) on the second display area (402) (e.g., position (518) of FIG. 5). The position corresponding to the protrusion distance may be a position determined based on the position of the three-dimensional image and the user's gaze position (e.g., position (507) of FIG. 5). For example, the display position of the two-dimensional image based on the protrusion distance may be a position determined based on the position of the three-dimensional image and the user's gaze position. To this end, the processor can determine the user's gaze position. For example, the user's gaze position may be a position determined by a sensor (e.g., sensor (403) of FIG. 4), a position tracked by eye tracking, or a position arbitrarily estimated by the processor.

[0162] FIG. 21 is a flowchart illustrating the operation of an electronic device according to one embodiment.

[0163] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIGS. 1, 4, 5, 6, 7, 8, 9, 10, 11, 13, 14, 15, 16, 17 and / or 18) may include a display (e.g., the display module (160) of FIG. 1) that includes a first display area (401) and a second display area (402).

[0164] According to one embodiment, a processor (e.g., processor (120) of FIG. 1) can display a three-dimensional image (e.g., three-dimensional images (501, 601, 701, 801, 901, 1001, 1101, 1102, 1301, 1401, 1411, 1501, 1601, 1701) of FIG. 5, FIG. 6, FIG. 7, FIG. 8, FIG. 9, FIG. 10, FIG. 11, FIG. 13, FIG. 14, FIG. 15, FIG. 16, FIG. 17, and / or FIG. 10) via a first display area (401) in operation 2101.

[0166] According to one embodiment, the processor may set a virtual camera position corresponding to the user's gaze position with respect to the second display area (402) based on the user's gaze position. For example, the user's gaze position may be a position identified by a sensor (e.g., sensor (403) of FIG. 4), for example, a position of the user's eyes tracked by eye tracking. For example, the user's gaze position may be a position estimated by the processor. For example, the user's gaze position may be pre-specified, such as a position moved vertically from a certain point (e.g., a center point or a center point of an upper edge) of the first display area screen by a specified distance (e.g., an end point of the second display area (402)). For example, the user's gaze position may be a position identified by a sensor (e.g., sensor (403) of FIG. 4), for example, a position of the user's eyes tracked by eye tracking.

[0167] According to one embodiment, the position of the virtual camera may be symmetrical with respect to the user's gaze position with respect to the second display area (402).

[0168] According to one embodiment, the processor may render a two-dimensional image corresponding to the three-dimensional image in operation 2105 and display it in the second display area (402). For example, the two-dimensional image may be displayed at a position where a line connecting the three-dimensional image to the position of the virtual camera intersects the second display area (402). Meanwhile, the virtual camera setting operation 2105 may be omitted, in which case the two-dimensional image may be determined based on, for example, a protrusion distance of the three-dimensional image.
