Description

How to display electronic devices and recent screens

[0001] The present disclosure relates to electronic devices and recent screen display methods.

[0002] Electronic devices such as smartphones, tablets, laptops, and wearables may include displays. As the size of displays within electronic devices increases, it has become possible to display multiple application screens or windows on the device.

[0003] While performing a task through multiple application screens or windows, users may briefly switch to the home screen or another application. During this time, the multiple application screens or windows that were running may be paused in the background.

[0004] After using the home screen or another application, if the user wishes to perform an action through multiple application launch screens or windows again, the user can request the electronic device to provide a list or image of recently used applications (e.g., the recent screen) and then select multiple application launch screens or windows. However, the electronic device does not display multiple application launch screens or windows simultaneously on the recent screen, so the user must rely on their memory to select the most recently launched application launch screen or window.

[0005] The electronic device and recent screen display method of the present disclosure can, while performing a task through multiple application execution screens or windows, if the user uses the home screen or another application for a moment, save the multiple application execution screens or windows as they are and provide them to the user upon request for display of the recent screen.

[0006] A recent screen display method of an electronic device of the present disclosure may include an operation of displaying at least two or more windows on a display.

[0007] A recent screen display method of an electronic device of the present disclosure may include an operation of saving at least two or more windows as an application group and displaying the other task when receiving a first user input requesting another task.

[0008] A method for displaying a recent screen of an electronic device of the present disclosure may include, upon receiving a second user input requesting display of a recent screen, displaying at least one recently used screen and a visual clue regarding a group of stored applications on the recent screen.

[0009] A method for displaying a recent screen of an electronic device of the present disclosure includes an operation of displaying a screen related to a group of applications on a display when a third user input for a visual cue is received, wherein each of the at least one recent screen corresponds to an execution screen of one application, and the screen related to the group of applications can correspond to execution screens of at least two applications.

[0010] The electronic device of the present disclosure may include a memory.

[0011] The electronic device of the present disclosure may include a display.

[0012] The electronic device of the present disclosure may include a processor.

[0013] The instructions stored in the memory of the present disclosure, when individually or collectively executed by the at least one processor, can cause the electronic device to display at least two or more windows on a display.

[0014] The instructions of the present disclosure, when individually or collectively executed by the at least one processor, can cause the electronic device to, upon receiving a first user input requesting another task, store at least two or more windows as an application group and display the other task.

[0015] The instructions of the present disclosure, when individually or collectively executed by the at least one processor, may cause the electronic device to display at least one recently used screen and a visual cue regarding a group of stored applications on a recent screen.

[0016] The instructions of the present disclosure, when individually or collectively executed by the at least one processor, cause the electronic device to, upon receiving a third user input for a visual cue, display a screen relating to a group of applications on the display, wherein each of the at least one recently used screen corresponds to a running screen of one application, and the screen relating to the group of applications may correspond to running screens of at least two applications.

[0017] The electronic device and recent screen display method of the present disclosure can store multiple application execution screens or windows as they are and provide them to the user upon request for display of recent screens, thereby making it easier for the user to resume a task that was temporarily interrupted.

In one embodiment, the auxiliary processor (123) (e.g., an image signal processor or a communication processor) may be implemented as a part of another functionally related component (e.g., a camera module (180) or a communication module (190)). In one embodiment, the auxiliary processor (123) (e.g., a neural network processing unit) may include a hardware structure specialized for processing artificial intelligence models. The artificial intelligence models may be generated through machine learning. This learning can be performed, for example, on the electronic device (101) itself where the artificial intelligence model is executed, or can be performed through a separate server (e.g., server (108)).

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).

[0053] 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.

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.

[0056] 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)).

[0057] 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).
