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).

[0070] 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.

[0073] 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)).

[0074] 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.

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.

[0075] FIG. 2a and FIG. 2b are drawings showing a screen display method of an electronic device (101) according to one embodiment of the present disclosure.

[0076] In one embodiment, the memory (130) may store instructions. The instructions, when executed by the processor (120), may cause the electronic device (101) to perform the screen display method of FIG. 2A.

[0077] In screen 201, instructions stored in memory (130), when executed by the processor (120), can cause the electronic device (101) to display a recent screen view on the display (160) based on user input.

[0078] On screen 201, when the recent screen view is executed, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display the recently used screens (211, 212, 213) of previously or currently running applications on the display (160).

[0079] On screen 201, on the recent screen view screen, each of the recent screens (211, 212, 213) of previously or currently running applications may include a thumbnail image.

[0080] On the 201 screen, when the recent screen view is executed, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display each of the recently used screens (211, 212, 213) of the previously or currently running applications in three dimensions on the display (160).

[0081] On the 201 screen, each of the recently used screens (211, 212, 213) of previously or currently running applications on the recent screen view screen may include an image rendered in perspective.

[0082] On screen 201, when the recent screen view is executed, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to start an operation of executing a multi-window when receiving a user input (221) for the first recent screen (211).

[0083] On the 201 screen, when the recent screen view is executed, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display a user interface of the recent screen view that can browse a plurality of recently used screens on the display (160). Each of the plurality of recently used screens may represent an execution screen of an application that has been previously executed or is currently being executed on the electronic device (101). The user interface of the recent screen view may provide interactions such as browsing the plurality of recently used screens, entering a multi-window mode, and / or executing a selected recently used screen in full screen.

[0084] On the 201 screen, when the recent screen view is executed, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to trigger an operation of executing a multi-window when receiving a user input (221) for the first recently used screen (211). The user input (221) can include a press input (e.g., a long press or a short press) for the first recently used screen (211). The user input (221) can include a press input and a drag input.

[0087] On the 202 screen, when an action to run a multi-window is triggered, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display a recently used screen (e.g., a first recently used screen (211)) selected according to a user input (e.g., a user input (221)) as a preview on the display (160).

[0088] In the 202 screen, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to arrange and display other recently used screens (e.g., other recently used screens (214)) other than the selected recently used screen (e.g., the first recently used screen (211)) on the display (160).

[0089] In screen 202, instructions stored in memory (130), when executed by the processor (120), can cause the electronic device (101) to display other recently used screens (e.g., other recently used screens (214)) other than the selected recently used screen (e.g., the first recently used screen (211)) as rendered images in perspective on the display (160).

[0090] In screen 202, instructions stored in memory (130), when executed by the processor (120), can cause the electronic device (101) to arrange and display on the display (160) the other recently used screens (214, 215)) other than the selected recently used screen (e.g., the first recently used screen (211)) as images rendered in perspective.

[0091] In the 202 screen, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display the selected recently used screen (e.g., the first recently used screen (211)) on the display (160) by reducing the size of the screen compared to before it was selected.

[0092] In the 202 screen, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to change the size of the selected recently used screen (e.g., the first recently used screen (211)) and display it on the display (160).

[0093] The user input (221) of screens 202, 203, and 204 may be a user input that is continuously input to the user input (221) of screen 201. The user input (221) of screens 202 and 203 may be a drag input.

[0094] The user input (221) of screens 202, 203, and 204 may be a moving user input while maintaining the user input (221) of screen 201.

[0095] In screen 202, instructions stored in memory (130), when executed by the processor (120), may cause the electronic device (101) to display on the display (160) a selected recently used screen (e.g., a first recently used screen (211)) based on user input (221).

[0096] In screen 202, a recently used screen (e.g., the first recently used screen (211)) may be displayed as an overlay on other recently used screens (214, 215).

[0097] In screen 202, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display on the display (160) a moving recently used screen (e.g., the first recently used screen (211)) overlaid on other recently used screens (214, 215)) according to user input (221).

[0098] In screen 203, when a selected recently used screen (e.g., a first recently used screen (211)) that is being moved according to a user input (221) is moved to a target recently used screen (e.g., a second recently used screen (214)), the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display the target recently used screen (e.g., the second recently used screen (214)) as a flat (or front) image on the display (160).

[0099] In one embodiment, a target recently used screen (e.g., a second recently used screen (214)) may be displayed in a multi-window together with a selected recently used screen (e.g., a first recently used screen (211)).

[0100] In screen 204, when a selected recently used screen (e.g., a first recently used screen (211)) that is being moved according to a user input (221) moves beyond a specific location of a target recently used screen (e.g., a second recently used screen (214)), instructions stored in memory (130) may, when executed by the processor (120), cause the electronic device (101) to display a preview image (231) on the display (160). Other recently used screens (e.g., other recently used screens (215)) other than the target recently used screen (e.g., the second recently used screen (214)) may be displayed on the display (160) as images with a rendered perspective.

[0101] In screen 204, the preview image (231) may include a target recently used screen (e.g., a second recently used screen (214)) and a selected recently used screen (e.g., a first recently used screen (211)). The preview image (231) may include a layout when displayed in a multi-window.

[0102] On screen 205, when the user input (221) is released, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display a target recently used screen (e.g., a second recently used screen (214)) and a selected recently used screen (e.g., a first recently used screen (211)) in a multi-window on the display (160).

[0103] On the 205 screen, when the user input (221) is released, the electronic device (101) can display a target recently used screen (e.g., the second recently used screen (214)) and a selected recently used screen (e.g., the first recently used screen (211)) in a split window on the display (160) under the control of the processor (120). The electronic device (101) can display a bar (241) between the target recently used screen (e.g., the second recently used screen (214)) and the selected recently used screen (e.g., the first recently used screen (211)) on the display (160) under the control of the processor (120). The electronic device (101) can move the bar according to the user input and display it on the display (160) under the control of the processor (120). Depending on the movement of the bar, the screen ratio of the target recently used screen (e.g., the second recently used screen (214)) and the selected recently used screen (e.g., the first recently used screen (211)) may change.

[0104] In screen 205, when the user input (221) is released, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display a target recently used screen (e.g., the second recently used screen (214)) and a selected recently used screen (e.g., the first recently used screen (211)) in a split window on the display (160). The instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display a bar (241) between the target recently used screen (e.g., the second recently used screen (214)) and the selected recently used screen (e.g., the first recently used screen (211)) on the display (160). The instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to move a bar according to user input and display it on the display (160).

[0105] FIG. 2c is a drawing showing a screen display method of an electronic device (101) according to one embodiment of the present disclosure.

[0106] On screen 206, instructions stored in memory (130), when executed by the processor (120), can cause the electronic device (101) to display a recent screen view on the display (160) based on user input.

[0107] On the 206 screen, when the recent screen view is executed, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display recently used screens (261) of previously or currently running applications on the display (160). Each of the recently used screens (261) can include a thumbnail image. Each of the recently used screens (261) can include an image rendered in perspective.

[0108] In screen 207, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to initiate an operation of executing a multi-window when receiving a user input for a selected recently used screen (262). When the operation of executing a multi-window is triggered, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display a preview of the selected recently used screen (262) on the display (160) according to the user input. The instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display other recently used screens, excluding the selected recently used screen (262), as images rendered in perspective on the display (160).

[0109] Referring to screens 207 and 208, when the selected recently used screen (262) is displayed as a preview, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display the selected recently used screen (262) in a reduced size compared to before.

[0110] On screen 207, when the selected recently used screen (262) that is moving according to user input moves to the target recently used screen, the electronic device (101) can display the target recently used screen as a flat (or front) image on the display (160) under the control of the processor (120).

[0111] In screen 207, when the selected recently used screen (262) that is being moved according to user input moves to the target recently used screen, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display the target recently used screen as a flat (or front) image on the display (160).

[0112] FIG. 3 is a flowchart illustrating a screen display method of an electronic device (101) according to one embodiment of the present disclosure.

[0113] In one embodiment, the memory (130) may store instructions. The instructions, when executed by the processor (120), may cause the electronic device (101) to perform the screen display method of FIG. 3.

[0114] In one embodiment, at operation 301, instructions stored in memory (130), when executed by the processor (120), may cause the electronic device (101) to display a recent screen view on the display (160) based on a first user input.

[0115] In one embodiment, in operation 301, when the recent screen view is executed, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display on the display (160) a user interface of the recent screen view that can browse a plurality of recently used screens. Each of the plurality of recently used screens may represent an execution screen of an application that has been previously executed or is currently being executed on the electronic device (101). The user interface of the recent screen view may provide interactions such as browsing the plurality of recently used screens, entering a multi-window mode, and / or executing a selected recently used screen in full screen.

[0116] In one embodiment, the display (160) may include a touch panel or touch sensor that receives a touch input. The first user input may include an input of swiping the display (160). For example, the electronic device (101) may receive the first user input on the display (160) while displaying a home screen or a running application screen. However, the present invention is not limited thereto, and the first user input may include a touch input for a control graphical user interface (GUI) on the display (160). The control GUI may include a GUI for a recent screen view. For example, upon receiving a touch input for a GUI for a recent screen view, the electronic device (101) may cause the recent screen view to be displayed on the display (160).

[0117] However, this is not limited to this, and action 301 may be omitted.

[0118] In one embodiment, in operation 303, instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to receive a second user input on a first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) while displaying a recent screen view. The first recently used screen may be included in the recent screen view.

[0119] In one embodiment, the second user input may include, for example, the user input (221) mentioned in FIGS. 2A and 2B. The second user input may include a press (e.g., a long press or a short press) input on a first recently used screen (e.g., the first recently used screen (211) of FIG. 2A). The second user input may include a press input and a drag input. The second user input may include a drag input that is continuous with the press input.

[0120] In one embodiment, in operation 303, when a second user input is received on a first recently used screen (e.g., the first recently used screen (211) of FIG. 2A), instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to perform a multi-window editing operation.

[0121] In one embodiment, in operation 303, when a second user input is received on a first recently used screen (e.g., the first recently used screen (211) of FIG. 2A), instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to enter a multi-window preview mode.

[0122] In one embodiment, in operation 303, when a second user input is received on a first recently used screen (e.g., the first recently used screen (211) of FIG. 2A), instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to determine that the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) has been selected.

[0123] In one embodiment, at operation 305, instructions stored in memory (130), when executed by processor (120), may cause electronic device (101) to display at least some of the recently used screens on display (160).

[0124] In one embodiment, at operation 305, instructions stored in memory (130), when executed by the processor (120), may cause the electronic device (101) to display other recently used screens as images rendered in perspective.

[0125] However, this is not limited thereto, and in operation 305, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display at least some of the recently used screens as images by rotating them about a specific axis or rendering them frontally without rotation.

[0126] In one embodiment, in operation 305, instructions stored in memory (130), when executed by the processor (120), may cause the electronic device (101) to display an image by rendering recently used screens in a form where they are lost to a single point.

[0127] In one embodiment, at operation 305, instructions stored in memory (130), when executed by the processor (120), may cause the electronic device (101) to display other recently used screens that have not been selected as perspective-rendered images.

[0128] In one embodiment, an image rendered in perspective may include an image with perspective applied, which is expressed in three dimensions based on a line by extending a line based on a vanishing point.

[0129] In one embodiment, the recently used screens displayed in the recent screen view may be displayed rotated around a specific axis (e.g., a vertical axis). Other recently used screens, excluding the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A), may include images rotated around the vertical axis.

[0130] In one embodiment, in operation 307, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display the second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) directly on the display (160) when the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) moves to the second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) or the target recently used screen (e.g., the second recently used screen (214) of FIG. 2A) in response to a second user input (e.g., a drag input).

[0131] In one embodiment, in operation 307, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display the second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) directly on the display (160) when the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) moves to the second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) or the target recently used screen (e.g., the second recently used screen (214) of FIG. 2A) while the second user input is maintained in response to the second user input (e.g., the drag input).

[0132] However, it is not limited thereto, and in operation 307, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to rotate the second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) along a specific axis or display the second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) on the display (160) facing forward without rotation when the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) moves to the second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) or the target recently used screen (e.g., the second recently used screen (214) of FIG. 2A) according to the second user input (e.g., the drag input). The instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to move the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) to the second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) or the target recently used screen (e.g., the second recently used screen (214) of FIG. 2A) in response to a second user input (e.g., a drag input), and then display the second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) on the display (160) in various ways.

[0133] In one embodiment, in operation 307, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display the layout as a preview image on the display (160) when the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) moves to a second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) or a target recently used screen (e.g., the second recently used screen (214) of FIG. 2A) among the recently used screens according to a second user input (e.g., a drag input).

[0134] In one embodiment, in operation 307, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display a first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) moving according to a second user input (e.g., a drag input) to a second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) or a target recently used screen (e.g., the second recently used screen (214) of FIG. 2A) in a flat surface without a three-dimensional effect.

[0135] In one embodiment, in operation 307, the instructions stored in the memory (130), when executed by the processor (120), cause the electronic device (101) to rotate an image being displayed in perspective to be displayed in a plane when a first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) that moves according to a second user input (e.g., a drag input) moves to a second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) or a target recently used screen (e.g., the second recently used screen (214) of FIG. 2A).

[0136] In one embodiment, operations 305 and 307 may be omitted.

[0137] In one embodiment, in operation 309, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display the layout as a preview image when a first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) that moves according to a second user input moves to a specific location of a target recently used screen (e.g., the second recently used screen (214) of FIG. 2A) when shown in a multi-window.

[0138] In one embodiment, in operation 309, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display the layout as a preview image when the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) that moves in response to the second user input moves to a specific location of the target recently used screen (e.g., the second recently used screen (214) of FIG. 2A) while the second user input is maintained in the multi-window preview mode, when shown in multi-window.

[0139] In one embodiment, the layout of the multi-window may be displayed differently depending on the position where the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) is placed on the second recently used screen (e.g., the second recently used screen (214) of FIG. 2A).

[0140] For example, depending on the position where the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) is placed on the second recently used screen (e.g., the second recently used screen (214) of FIG. 2A), the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) may be displayed at the top of the multi-window, and the second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) may be displayed at the bottom of the multi-window. However, it is not limited thereto, and depending on the position where the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) is placed on the second recently used screen (e.g., the second recently used screen (214) of FIG. 2A), the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) may be displayed at the bottom of the multi-window, and the second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) may be displayed at the bottom of the multi-window. Depending on the position where the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) is placed on the second recently used screen (e.g., the second recently used screen (214) of FIG. 2A), the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) may be overlaid on the second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) and displayed as a pop-up window.

[0141] In one embodiment, in operation 311, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display a multi-window including a first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) and a second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) based on the display of the preview image.

[0142] In one embodiment, in operation 311, when the second user input is released while the preview image is being displayed, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display a multi-window including a first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) and a second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) based on the display of the preview image.

[0143] In one embodiment, in operation 311, when a specified time is reached while the preview image is being displayed, instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display a multi-window including a first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) and a second recently used screen (e.g., the second recently used screen (214) of FIG. 2A) based on the display of the preview image.

[0144] FIG. 4 is a drawing showing a screen display method of an electronic device (101) according to one embodiment of the present disclosure.

[0145] In one embodiment, the screen display method of FIG. 4 may recommend applications that can be displayed together in a multi-window.

[0146] In one embodiment, the memory (130) can store instructions. The instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to perform the screen display method of FIG. 4.

[0147] In screen 401, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display a screen (411) corresponding to the application running on the display (160). However, this is not limited thereto, and in screen 401, the screen displayed on the display (160) can include one of a screen corresponding to the application running, a home screen, or a lock screen.

[0148] On screen 401, while displaying a screen (411) corresponding to a running application, instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to determine whether a third user input (220) has been received.

[0149] In the 402 screen, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display a recent screen view (e.g., recents view) on the display (160) based on a third user input (220). When the recents view is executed, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display one or more recent screens (412, 413, 414) on the display (160). For example, when the recent screen view is executed, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display the third most recently used screen (412), the fourth most recently used screen (413), and the fifth most recently used screen (414) on the display (160).

[0150] In screen 402, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to receive user input (221) for the third most recently used screen (412). Upon receiving user input (221) for the third most recently used screen (412), the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to enter a multi-window preview mode.

[0151] On the 402 screen, when the recent screen view is executed, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display a user interface of the recent screen view that can browse a plurality of recently used screens on the display (160). Each of the plurality of recently used screens may represent an execution screen of an application that has been previously executed or is currently being executed on the electronic device (101). The user interface of the recent screen view may provide interactions such as browsing the plurality of recently used screens, entering a multi-window mode, and / or executing a selected recently used screen in full screen.

[0152] On screen 403, when entering the multi-window preview mode, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to check whether there is a recommended application.

[0153] For example, the third most recently used screen (412) that received the user input (221) may include a screen for executing or using a third application. The third most recently used screen (412) may correspond to a screen for executing or using a third application.

[0154] In one embodiment, the criteria for selecting a recommended application by the electronic device (101) may be based on at least one of the multi-window usage history learned in relation to the third application, the association between the third application and the recommended application, the category between the third application and the recommended application, or the usage time of the recommended application.

[0155] In one embodiment, the electronic device (101) may recommend an application that has been used consecutively at an adjacent time or location based on current time and / or current location information acquired by the electronic device (101) among applications that have not been used recently.

[0156] For example, if there is a learned multi-window usage history related to a third application, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display a recently used screen related to the recommended application on the display (160).

[0240] In the 903 screen, instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to initiate an operation of executing a multi-window when receiving a user input (221) for one of the recently used screens (e.g., the sixth recently used screen (621), the seventh recently used screen (622), and the eighth recently used screen (623)).

[0241] In the 904 screen, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display the layout as a preview image on the display (160) when the 8th most recently used screen (623) that moves according to the user input (221) moves to a specific location on the 6th most recently used screen (621), when shown in multi-window.

[0242] In the 904 screen, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display the layout as a preview image on the display (160) when the eighth most recently used screen (623) moving according to the user input (221) moves to a specific location of the sixth most recently used screen (621) while the user input (221) is maintained in the multi-window preview mode, when shown in multi-window.

[0243] On the 904 screen, while displaying a preview image for a multi-window, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display a home button (811) on at least a portion of the display (160).

[0244] For example, when a user input is received on the home button (811), instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to terminate the operation of executing the multi-window and display the home screen.

[0245] For example, when the 8th most recent screen (623) that moves according to user input (221) is moved to the home button (811) and then the user input (221) is released, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to terminate the operation of executing the multi-window and display the home screen.

[0246] For example, when the 8th most recent screen (623) that moves according to user input (221) is moved to the home button (811) and a specified time has elapsed, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to terminate the operation of executing the multi-window and display the home screen.

[0247] FIG. 10 is a flowchart showing an operation of terminating the multi-window preview mode of the electronic device (101) of the present disclosure.

[0248] In one embodiment, in operation 1001, instructions stored in memory (130), when executed by the processor (120), may cause the electronic device (101) to display a recent screen view on the display (160) based on a first user input. The first user input may include the first user input mentioned in FIG. 3. However, the present invention is not limited thereto, and operation 1001 may be omitted.

[0249] In one embodiment, in operation 1001, when the recent screen view is executed, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display on the display (160) a user interface of the recent screen view that can browse a plurality of recently used screens. Each of the plurality of recently used screens may represent an execution screen of an application that has been previously executed or is currently being executed on the electronic device (101). The user interface of the recent screen view may provide interactions such as browsing the plurality of recently used screens, entering a multi-window mode, and / or executing a selected recently used screen in full screen.

[0250] In one embodiment, at operation 1003, instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to receive a second user input on a first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) while displaying a recent screen view. The first recently used screen may be included in the recent screen view.

[0251] In one embodiment, the second user input may include, for example, the user input (221) referred to in FIGS. 2a, 2b, 2c, 3 and 4.

[0252] In one embodiment, in operation 1003, when a second user input is received on a first recently used screen (e.g., the first recently used screen (211) of FIG. 2A), instructions stored in the memory (130) may, when executed by the processor (120), cause the electronic device (101) to perform a multi-window operation.

[0253] In one embodiment, in operation 1003, when a second user input is received on a first recently used screen (e.g., the first recently used screen (211) of FIG. 2A), instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to enter a multi-window preview mode.

[0254] In one embodiment, in operation 1003, when a second user input is received on a first recently used screen (e.g., the first recently used screen (211) of FIG. 2A), instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to determine that the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) has been selected.

[0255] In one embodiment, at operation 1005, instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to move a first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) on the display (160) in response to a second user input.

[0256] In one embodiment, at operation 1007, instructions stored in memory (130), when executed by the processor (120), may determine whether the instructions correspond to a condition for causing the electronic device (101) to terminate preview images for a multi-window.

[0257] In one embodiment, in operation 1007, instructions stored in memory (130), when executed by the processor (120), may determine whether the instructions correspond to a condition that causes the electronic device (101) to terminate multi-window execution.

[0258] For example, after the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) is moved to the home card (e.g., the home card (631) of FIG. 6 or the home card (710) of FIG. 7) in response to a second user input, when the second user input is released, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to terminate the operation of executing the multi-window.

[0259] For example, after a specified time has elapsed after the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) is moved to the home card (e.g., the home card (631) of FIG. 6 or the home card (710) of FIG. 7) according to a second user input, instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to terminate the operation of executing the multi-window.

[0260] For example, when a user input is received on a home button (e.g., the home button (811) of FIG. 8), instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to terminate the operation of executing a multi-window and display the home screen.

[0261] For example, when the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) is moved to the home button (e.g., the home button (811) of FIG. 8) according to the second user input and the user input (221) is released, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to terminate the operation of executing the multi-window and display the home screen.

[0262] For example, when a specified time has elapsed after the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) is moved to the home button (e.g., the home button (811) of FIG. 8) according to a second user input, instructions stored in the memory (130) can, when executed by the processor (120), cause the electronic device (101) to terminate the operation of executing the multi-window and display the home screen.

[0263] For example, when a user input is received on a cancel button (e.g., the cancel button (812) of FIG. 8), instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to terminate the operation of executing the multi-window.

[0264] For example, when the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) is moved to a cancel button (e.g., the cancel button (812) of FIG. 8) according to a second user input and then the user input (221) is released, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to terminate the operation of executing the multi-window.

[0265] For example, when a specified time has elapsed after the first most recently used screen (e.g., the first most recently used screen (211) of FIG. 2A) is moved to a cancel button (e.g., the cancel button (812) of FIG. 8) according to a second user input, instructions stored in the memory (130) may, when executed by the processor (120), cause the electronic device (101) to terminate the operation of executing the multi-window.

[0266] For example, when a user input is received on a home button (e.g., the home button (811) of FIG. 8), instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to terminate the operation of executing a multi-window and display the home screen.

[0267] For example, when the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) is moved to the home button (e.g., the home button (811) of FIG. 8) according to the second user input and then the second user input is released, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to terminate the operation of executing the multi-window and display the home screen.

[0268] For example, when a specified time has elapsed after the first recently used screen (e.g., the first recently used screen (211) of FIG. 2A) is moved to the home button (e.g., the home button (811) of FIG. 8) according to a second user input, instructions stored in the memory (130) can, when executed by the processor (120), cause the electronic device (101) to terminate the operation of executing the multi-window and display the home screen.

[0269] In one embodiment, in response to a condition for terminating a preview image for a multi-window, instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to branch from operation 1007 to operation 1009.

[0270] In one embodiment, if the condition for terminating the preview image for the multi-window is not met, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to branch from operation 1007 to operation 1005.

[0271] In one embodiment, at operation 1009, instructions stored in memory (130), when executed by the processor (120), may cause the electronic device (101) to terminate the operation of displaying a preview image for a multi-window.

[0272] FIG. 11A and FIG. 11B are drawings showing a screen display method of an electronic device (101) according to one embodiment of the present disclosure.

[0273] On the 1101 screen, when the recent screen view is executed, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display each of the recently used screens (1111, 1112, 1113) of previously or currently running applications in three dimensions on the display (160). The recently used screens (1111, 1112, 1113) can include the ninth recently used screen (1111), the tenth recently used screen (1112), or the eleventh recently used screen (1113).

[0274] On the 1101 screen, each of the recent screens (1111, 1112, 1113) of previously or currently running applications on the recent screen view screen may include an image rendered in perspective.

[0275] On the 1101 screen, when the recent screen view is executed, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display a user interface of the recent screen view that can browse a plurality of recently used screens on the display (160). Each of the plurality of recently used screens may represent an execution screen of an application that has been previously executed or is currently being executed on the electronic device (101). The user interface of the recent screen view may provide interactions such as browsing the plurality of recently used screens, entering a multi-window mode, and / or executing a selected recently used screen in full screen.

[0276] In the 1101 screen, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to start an operation of executing a multi-window when receiving a user input (221) for the 9th most recently used screen (1111).

[0277] On the 1101 screen, when the recent screen view is executed, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to start an operation of executing a multi-window when receiving a user input (221) for the 9th recent screen (1111).

[0278] On the 1102 screen, when the multi-window is executed, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to resize and display the ninth most recently used screen (1111). The size of the ninth most recently used screen (1111) may be resized to a size corresponding to at least one window among the multi-windows. The resizing of the ninth most recently used screen (1111) may include reducing the length of the long axis among the long axis and the short axis.

[0279] On the 1102 screen, when an action to run a multi-window is triggered, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display a preview of the ninth most recently used screen (1111) selected according to a user input (e.g., user input (221)) on the display (160).

[0280] In the 1102 screen, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to arrange and display on the display (160) other recently used screens (e.g., the 10th recently used screen (1112) or the 11th recently used screen (1113)) other than the selected 9th recently used screen (1111).

[0281] In the 1102 screen, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display other recently used screens (e.g., the 10th recently used screen (1112) or the 11th recently used screen (1113)) other than the selected 9th recently used screen (1111) as rendered images in perspective on the display (160).

[0282] In the 1102 screen, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display on the display (160) other recently used screens (214, 215)) other than the selected recently used screen (e.g., the first recently used screen (211)) arranged as images rendered in perspective.

[0283] On the 1102 screen, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display on the display (160) the ninth most recently used screen (1111) selected based on the user input (221).

[0284] In the 1102 screen, the 9th most recently used screen (1111) may be displayed as an overlay on other most recently used screens (e.g., the 11th most recently used screen (1113)).

[0285] In the 1103 screen, when the 9th recently used screen (1111) moving according to the user input (221) reaches a first specific position of the target recently used screen (e.g., the 11th recently used screen (1113)), the instructions stored in the memory (130) can, when executed by the processor (120), cause the electronic device (101) to display a multi-window including the 9th recently used screen (1111) and the target recently used screen (e.g., the 11th recently used screen (1113)) as a preview image.

[0286] For example, the first specific location may include a location between the bottom and about 30% from the bottom of the target recent use screen (e.g., the 11th recent use screen (1113)).

[0287] In the 1103 screen, when the 9th recently used screen (1111) reaches a first specific position of a target recently used screen (e.g., the 11th recently used screen (1113)), the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display a multi-window including the 9th recently used screen (1111) at the bottom of the multi-window and including the target recently used screen (e.g., the 11th recently used screen (1113)) at the top of the multi-window as a preview image.

[0288] On the 1104 screen, when the 9th most recently used screen (1111) moving according to the user input (221) reaches the second specific position of the target most recently used screen (e.g., the 11th most recently used screen (1113)), the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display a multi-window including the 9th most recently used screen (1111) and the target most recently used screen (e.g., the 11th most recently used screen (1113)) as a preview image.

[0289] For example, the second specific location may include a location between about 30% from the bottom and about 30% from the top of the target recent use screen (e.g., the eleventh recent use screen (1113)).

[0290] In the 1104 screen, when the 9th recently used screen (1111) reaches a second specific position of the target recently used screen (e.g., the 11th recently used screen (1113)), the instructions stored in the memory (130) can, when executed by the processor (120), cause the electronic device (101) to display the 9th recently used screen (1111) displayed as a pop-up window over the target recently used screen (e.g., the 11th recently used screen (1113)) to display the multi-window as a preview image.

[0291] In the 1105 screen, when the 9th most recently used screen (1111) moving according to the user input (221) reaches the third specific position of the target most recently used screen (e.g., the 11th most recently used screen (1113)), the instructions stored in the memory (130) can, when executed by the processor (120), cause the electronic device (101) to display a multi-window including the 9th most recently used screen (1111) and the target most recently used screen (e.g., the 11th most recently used screen (1113)) as a preview image.

[0292] For example, the third specific location may include a location between the top and about 30% from the top of the target recent use screen (e.g., the eleventh recent use screen (1113)).

[0293] In the 1105 screen, when the 9th recently used screen (1111) reaches a third specific position of the target recently used screen (e.g., the 11th recently used screen (1113)), the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display a multi-window including the 9th recently used screen (1111) at the top of the multi-window and including the target recently used screen (e.g., the 11th recently used screen (1113)) at the bottom of the multi-window as a preview image.

[0294] On the 1106 screen, when the user input (221) is released, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display the preview image on the display (160) in a multi-window.

[0295] On the 1106 screen, when the 9th most recently used screen (1111) moved according to the user input (221) stays at a specific location of the target most recently used screen (e.g., the 11th most recently used screen (1113)) for a specified period of time, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display a preview image on the display (160) in a multi-window.

[0296] FIG. 12a and FIG. 12b are drawings showing a screen display method of an electronic device (101) according to one embodiment of the present disclosure.

[0297] In the 1201 screen, when the 12th most recently used screen (1211) moving according to the user input (221) reaches the second specific position of the target most recently used screen (e.g., the 13th most recently used screen (1212)), the instructions stored in the memory (130) can, when executed by the processor (120), cause the electronic device (101) to display a multi-window including the 12th most recently used screen (1211) and the target most recently used screen (e.g., the 13th most recently used screen (1212)) as a preview image.

[0298] For example, the second specific location may include a location between about 30% (B) from the bottom and about 30% (A) from the top of the target recent use screen (e.g., the eleventh recent use screen (1113)).

[0299] In the 1201 screen, when the 12th most recently used screen (1211) reaches the second specific position of the target most recently used screen (e.g., the 13th most recently used screen (1212)), the instructions stored in the memory (130) can, when executed by the processor (120), cause the electronic device (101) to display the multi-window as a preview image by overlaying the 9th most recently used screen (1111) displayed as a pop-up window on the target most recently used screen (e.g., the 11th most recently used screen (1113)).

[0300] In screen 1202, when a specified time has elapsed after the 12th most recently used screen (1211) reaches a second specific location on a target most recently used screen (e.g., the 13th most recently used screen (1212)), instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display a guide interface (1220) indicating a location where a pop-up window is to be displayed on the target most recently used screen (e.g., the 13th most recently used screen (1212)).

[0301] For example, the location where the pop-up window will be displayed on the target recent use screen (e.g., the 13th recent use screen (1212)) may include one of the nine locations where the target recent use screen is divided.

[0302] In the 1203 screen, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to move the 12th most recently used screen (1211) to one of the nine locations where the target most recently used screen is divided according to user input (221).

The recently used screens (1511, 1513, 1514) can include a 14th recently used screen (1511), a 15th recently used screen (1513), or a 16th recently used screen (1514). On the recent screen view screen, each of the recently used screens (1511, 1513, 1514) of previously or currently running applications can include a thumbnail image. On the recent screen view screen, instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display each of the recently used screens (1511, 1513, 1514) of previously or currently running applications in three dimensions on the display (160). On the recent screen view screen, each of the recently used screens (1511, 1513, 1514) of previously or currently running applications can include an image rendered in perspective.

[0319] On the 1501 screen, when the recent screen view is executed, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display a user interface of the recent screen view that can browse a plurality of recently used screens on the display (160). Each of the plurality of recently used screens may represent an execution screen of an application that has been previously executed or is currently being executed on the electronic device (101). The user interface of the recent screen view may provide interactions such as browsing the plurality of recently used screens, entering a multi-window mode, and / or executing a selected recently used screen in full screen.

[0320] In the 1501 screen, instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to start an operation of executing a multi-window when receiving a user input (221) for the 14th most recently used screen (1511).

[0321] In the 1501 screen, instructions stored in the memory (130), when executed by the processor (120), may trigger an operation to execute a multi-window when the electronic device (101) receives a user input (221) for the 14th most recently used screen (1511).

[0322] In screen 1501, the user input (221) may include a long press input for any one of the recently used screens (1511, 1513, 1514) (e.g., the 14th recently used screen (1511)). However, the present invention is not limited thereto, and the user input (221) may be a touch input for any one of the recently used screens (1511, 1513, 1514) (e.g., the 14th recently used screen (1511)).

[0323] In the 1502 screen, when a selected recently used screen (e.g., the 14th recently used screen (1511)) that is being moved according to a user input (221) is moved to a target recently used screen (e.g., the 16th recently used screen (1514)), the instructions stored in the memory (130) can, when executed by the processor (120), cause the electronic device (101) to display the target recently used screen (e.g., the 16th recently used screen (1514)) as a flat (or frontal) image on the display (160).

[0324] In screen 1502, when a selected recently used screen (e.g., the 14th recently used screen (1511)) moving according to a user input (221) reaches a specific location (e.g., the first specific location in FIG. 11) of a target recently used screen (e.g., the 16th recently used screen (1514)), instructions stored in the memory (130) may, when executed by the processor (120), cause the electronic device (101) to display a preview image (1531) on the display (160). The preview image (1531) may include the target recently used screen (e.g., the 16th recently used screen (1514)) and the selected recently used screen (e.g., the 11th recently used screen (1511)). The preview image (1531) may include a layout when displayed in a multi-window. The preview image (1531) may include a layout in which a selected recently used screen (e.g., the 14th recently used screen (1511)) is positioned at the bottom and a target recently used screen (e.g., the 16th recently used screen (1514)) is positioned at the top.

[0325] In screens 1502 and 1503, when a selected recently used screen (e.g., the 14th recently used screen (1511)) being moved according to a user input (221) moves beyond the critical areas (C, D) of a target recently used screen (e.g., the 16th recently used screen (1514)), the instructions stored in the memory (130) can cause the electronic device (101) to disable the display of the preview image (1531) when executed by the processor (120). When a recently used screen (e.g., the 14th recently used screen (1511)) moves on the recent screen view, the instructions stored in the memory (130) can cause the electronic device (101) to display the 17th recently used screen (1515) and the 18th recently used screen (1516) on the display (160).

[0326] In the 1504 screen, when a selected recently used screen (e.g., the 14th recently used screen (1511)) that is being moved according to a user input (221) is moved to a target recently used screen (e.g., the 18th recently used screen (1516)), the instructions stored in the memory (130) can, when executed by the processor (120), cause the electronic device (101) to display the target recently used screen (e.g., the 18th recently used screen (1516)) as a flat (or frontal) image on the display (160).

[0327] In screen 1504, when a selected recently used screen (e.g., the 14th recently used screen (1511)) moving according to user input (221) reaches a specific location (e.g., the first specific location in FIG. 11) of a target recently used screen (e.g., the 18th recently used screen (1516)), instructions stored in memory (130) can cause the electronic device (101) to display a preview image (1532) on the display (160) when executed by the processor (120).

[0328] In one embodiment, the preview image (1532) may include a target recently used screen (e.g., the 18th recently used screen (1516)) and a selected recently used screen (e.g., the 14th recently used screen (1511)). The preview image (1532) may include a layout when displayed in a multi-window. The preview image (1532) may include a layout in which the selected recently used screen (e.g., the 14th recently used screen (1511)) is positioned at the bottom and the target recently used screen (e.g., the 18th recently used screen (1516)) is positioned at the top.

[0329] In the 1505 screen, when the user input (221) is released, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display a target recently used screen (e.g., the 18th recently used screen (1516)) and a selected recently used screen (e.g., the 14th recently used screen (1511)) in a multi-window on the display (160). The instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to further display a bar (1541) between the target recently used screen (e.g., the 18th recently used screen (1516)) and the selected recently used screen (e.g., the 14th recently used screen (1511)) on the display (160). The instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to move a bar according to a user input and display it on the display (160). Depending on the movement of the bar, the screen ratio of the target recently used screen (e.g., the 18th recently used screen (1516)) and the selected recently used screen (e.g., the 14th recently used screen (1511)) can change.

[0330] FIG. 16a and FIG. 16b are drawings showing a screen display method of an electronic device (101) according to one embodiment of the present disclosure.

[0331] On screen 1601, the electronic device (101) can display a recent screen view on the display (160) based on user input under the control of the processor (120).

[0332] In the 1601 screen, when the recent screen view is executed, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display recently used screens (1611, 1612, 1613) of previously or currently running applications on the display (160).

Each of the plurality of recently used screens may represent an execution screen of an application that has been previously executed or is currently being executed on the electronic device (101). The user interface of the recent screen view may provide interactions such as browsing the plurality of recently used screens, entering a multi-window mode, and / or executing a selected recently used screen in full screen.

[0334] In the 1601 screen, instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to start an operation of executing a multi-window when receiving a user input (221) for the 19th most recently used screen (1611).

[0335] In the 1601 screen, instructions stored in the memory (130), when executed by the processor (120), may trigger an operation to execute a multi-window when the electronic device (101) receives a user input (221) for the 19th most recently used screen (1611).

[0336] In screen 1601, the user input (221) may include a long press input for any one of the recently used screens (1611, 1612, 1613) (e.g., the 19th recently used screen (1611)). However, the present invention is not limited thereto, and the user input (221) may be a touch input for any one of the recently used screens (1611, 1612, 1613) (e.g., the 19th recently used screen (1611)).

[0337] In the 1602 screen, when the selected recently used screen (e.g., the 19th recently used screen (1611)) being moved according to the user input (221) moves to the target recently used screen (e.g., the 20th recently used screen (1612)), the instructions stored in the memory (130) can, when executed by the processor (120), cause the electronic device (101) to display the target recently used screen (e.g., the 20th recently used screen (1612)) as a flat (or front) image on the display (160).

[0338] In screen 1602, when a selected recently used screen (e.g., the 19th recently used screen (1611)) moving according to a user input (221) reaches a specific location (e.g., the first specific location in FIG. 11) of a target recently used screen (e.g., the 20th recently used screen (1612)), instructions stored in the memory (130) may, when executed by the processor (120), cause the electronic device (101) to display a preview image (1631) on the display (160). The preview image (1631) may include the target recently used screen (e.g., the 20th recently used screen (1612)) and the selected recently used screen (e.g., the 19th recently used screen (1611)). The preview image (1631) may include a layout when displayed in a multi-window. The preview image (1631) may include a layout in which a selected recently used screen (e.g., the 19th recently used screen (1611)) is positioned at the bottom and a target recently used screen (e.g., the 20th recently used screen (1612)) is positioned at the top.

[0339] In the 1603 screen, when the selected recently used screen (e.g., the 19th recently used screen (1611)) moving according to the user input (221) moves to the first release area (1651) or the second release area (1652) and then the user input (221) is released, the instructions stored in the memory (130) can, when executed by the processor (120), cause the electronic device (101) to display the selected recently used screen (e.g., the 19th recently used screen (1611)) at the location where the user input (221) was released.

[0340] On the 1603 screen, when a selected recently used screen (e.g., the 19th recently used screen (1611)) moving according to a user input (1621) moves to the first release area (1651) or the second release area (1652) and then the user input (1621) is released, the instructions stored in the memory (130) can cause the electronic device (101) to execute a single window when executed by the processor (120). The first release area (1651) or the second release area (1652) can include an area located below or above the recent screen view on the display (160). The instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to trigger a single window when the touch input is released after reaching the first release area (1651) or the second release area (1652).

[0341] In the 1603 screen, when the user input (221) is released after the selected recently used screen (e.g., the 19th recently used screen (1611)) moving according to the user input (221) reaches the first release area (1651) or the second release area (1652), the instructions stored in the memory (130) can cause the electronic device (101) to extend and display the target recently used screen (e.g., the 20th recently used screen (1612)).

[0342] In the 1603 screen, when the selected recently used screen (e.g., the 19th recently used screen (1611)) moving according to the user input (221) moves to the first release area (1651) or the second release area (1652) and then the user input (221) is released, the instructions stored in the memory (130), when executed by the processor (120), can trigger the electronic device (101) to display a single window on the display (160).

[0343] In the 1604 screen, when the selected recently used screen (e.g., the 19th recently used screen (1611)) that is being moved according to the user input (221) is moved to the first release area (1651) or the second release area (1652) and then the user input (221) is released, the instructions stored in the memory (130) can cause the electronic device (101) to extend and display the selected recently used screen (e.g., the 20th recently used screen (1611)) when executed by the processor (120).

[0344] In screens 1604 and 1605, the instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to receive user input (221) again for the recently used screen (e.g., the 19th recently used screen (1611)) being expanded and displayed. For example, the recently used screen (e.g., the 20th recently used screen (1611)) being expanded and displayed may be moved based on the user input (221). The instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to display on the display (160) that the recently used screen (e.g., the 19th recently used screen (1611)) is moved according to the user input (221). The instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display on the display (160) a recently used screen (e.g., the 19th recently used screen (1611)) arranged among other recently used screens (1612, 1614) according to a user input (221).

[0345] FIG. 17 is a flowchart illustrating a screen display method of an electronic device (101) according to one embodiment of the present invention.

[0444] FIG. 25a and FIG. 25b are drawings showing a screen display method of an electronic device (101) according to one embodiment of the present disclosure.

[0445] In one embodiment, the memory (130) can store instructions. The instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to perform the screen display method of FIG. 25.

[0446] In screen 2501, instructions stored in memory (130), when executed by processor (120), can cause electronic device (101) to display a screen (2511) corresponding to an application running on the display (160). However, this is not limited thereto, and in screen 2501, the screen displayed on the display (160) can include one of a screen corresponding to an application running, a home screen, or a lock screen.

[0447] On screen 2501, while displaying a screen (2511) corresponding to a running application, instructions stored in memory (130), when executed by the processor (120), can cause the electronic device (101) to determine whether a third user input (220) has been received.

[0448] On screen 2501, upon receiving a third user input (220), instructions stored in memory (130), when executed by the processor (120), may cause the electronic device (101) to execute a recent screen view. The recent screen view may include a 29th recently used screen (2312) and a 30th recently used screen (2313).

[0449] On the 2502 screen, instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to receive multi-touch input (2520).

[0450] In the 2502 screen, instructions stored in the memory (130), when executed by the processor (120), may cause the electronic device (101) to receive a multi-touch input (2520) for the 29th most recently used screen (2312).

[0451] On the 2503 screen, when a multi-touch input (2520) for the 29th most recently used screen (2312) is received, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to determine whether there is a history of creating a multi-window using the 29th most recently used screen (2312) and whether there is a combination pattern based on an application that can create a multi-window together with the 29th most recently used screen (2312).

[0452] If there is no history of creating a multi-window using the 29th most recently used screen (2312) or if there is no combination pattern based on an application that can create a multi-window with the 29th most recently used screen (2312), then in screen 2506, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display a multi-window including the 29th most recently used screen (2312) based on a predefined pattern.

[0453] If there is a history of creating a multi-window using the 29th most recently used screen (2312) and a combination pattern based on an application that can create a multi-window together with the 29th most recently used screen (2312), then in the 2504 screen, instructions stored in the memory (130) can, when executed by the processor (120), cause the electronic device (101) to automatically create a layout of the multi-window and display it as a preview image (2511).

[0454] For example, if the 29th most recently used screen (2312) is a game execution screen and the application that can create a multi-window together with the 29th most recently used screen (2312) is a video playback application, the screen ratio of the video playback application and the game application within the multi-window can be made larger than the screen ratio of the game application, which requires more focus on the video.

[0455] On the 2505 screen, when the multi-touch input (2520) is released, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to display a multi-window based on the preview image (2511).

[0456] The preview image (2511) may include a visual cue. For example, the preview image (2511) or the visual cue may be displayed as an overlay over at least a portion of the recent screen view. The preview image (2511) or the visual cue may be displayed as an overlay over at least a portion of the recent screen view in a translucent or opaque manner. The preview image (2511) or the visual cue may include a screen regarding a multi-window including recently used screens selected by a multi-touch input (e.g., a multi-touch input (2520)).

For example, the 31st most recently used screen (2611) and the 32nd most recently used screen (2612) may have the same horizontal and vertical length ratio. When the vertical length of the 31st most recently used screen (2611) is L2 and the vertical length of the 32nd most recently used screen (2612) is L1, the lengths of L1 and L2 may be equal to each other.

[0460] In the 2602 screen, the instructions stored in the memory (130), when executed by the processor (120), can cause the electronic device (101) to automatically generate a layout of the multi-window so that the upper window is smaller than the lower window and display it as a preview image (2511) or a multi-window (2505 screen). For example, the 31st most recently used screen (2611) and the 32nd most recently used screen (2612) may have the same horizontal length but different vertical length ratios. When the vertical length of the 31st most recently used screen (2611) is L3 and the vertical length of the 32nd most recently used screen (2612) is L4, the lengths of L3 and L4 are different and the ratio may be 3:1.
