[0001] The present disclosure relates to an electronic device for controlling a screen of a display and a method of operating the same, according to one embodiment.

[0002] On electronic device displays, displaying white consumes more power than displaying black. Because electronic device displays consume significant power, there's a growing need for power-saving features to reduce power consumption. Typically, operating systems provide power-saving features that turn off the display after a certain period of inactivity, rendering the device unusable.

[0003] According to one embodiment, an electronic device may include a display, at least one processor, and a memory storing instructions. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to set first power-saving regions on the display. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to identify a screen change event detecting a change of a screen in a first region of the first power-saving regions. The instructions, when individually or collectively executed by the at least one processor, may cause the electronic device to display a screen on the display by applying different power-saving effects to a first region corresponding to the screen change event and a second region not corresponding to the screen change event, among the first power-saving regions.

[0004] According to one embodiment, a method of operating an electronic device may include an operation of setting first power-saving areas on a display of the electronic device. The method may include an operation of identifying a screen change event that detects a screen change in a first area of ​​the first power-saving areas. The method may include an operation of displaying a screen on the display by applying different power-saving effects to a first area corresponding to the screen change event and a second area not corresponding to the screen change event, among the first power-saving areas.

[0005] According to one embodiment, a non-transitory computer-readable recording medium storing instructions may cause the instructions, when individually or collectively executed by at least one processor of an electronic device, to cause the electronic device to perform at least one operation. The at least one operation may include setting first power-saving areas on a display of the electronic device. The at least one operation may include identifying a screen change event that detects a change of a screen in a first area of ​​the first power-saving areas. The at least one operation may include applying different power-saving effects to a first area corresponding to the screen change event and a second area not corresponding to the screen change event, among the first power-saving areas, thereby displaying a screen on the display.

For example, when the electronic device (101) includes the main processor (121) and the auxiliary processor (123), the auxiliary processor (123) may be configured to use less power than the main processor (121) or to be specialized for a given function. The auxiliary processor (123) may be implemented separately from the main processor (121) or as a part thereof.

[0038] The auxiliary processor (123) may control at least a portion of functions or states associated with at least one component (e.g., a display module (160), a sensor module (176), or a communication module (190)) of the electronic device (101), for example, on behalf of the main processor (121) while the main processor (121) is in an inactive (e.g., sleep) state, or together with the main processor (121) while the main processor (121) is in an active (e.g., application execution) state. 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)).

[0051] 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.

[0052] 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).

[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. 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 realizing 1eMBB, a loss coverage (e.g., 164 dB or less) for realizing mMTC, 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 realizing URLLC.

[0054] 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).

[0055] According to various embodiments, 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.

[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). 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.

[0058] FIG. 2A is a block diagram of an electronic device (101) according to one embodiment.

[0059] The electronic device (101) of FIG. 2A may be the electronic device (101) of FIG. 1 or a device similar to the electronic device (101) of FIG. 1. The electronic device (101) of FIG. 2A may include components that are identical or similar to those of the electronic device (101) of FIG. 1. The operation of the electronic device (101) of FIG. 2A may be understood as the operation of the electronic device (101) of FIG. 1 (e.g., components of the electronic device (101) of FIG. 1). For example, the electronic device (101) of FIG. 2A may be, but is not limited to, a notebook computer, a tablet, a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, or a home appliance device.

[0060] Referring to FIG. 2A, according to one embodiment, the electronic device (101) may include a display (260), a battery (189), a processor (120), and / or a memory (130).

[0061] According to one embodiment, the display (260) may be included in the display module (160) of FIG. 1. According to one embodiment, the display (260) may be a foldable display (e.g., 230 of FIG. 2B), as described later in FIG. 2A, but this is exemplary, and the display (260) may also be a flat display, and there is no limitation on the type of the display (260).

[0062] According to one embodiment, the electronic device (101) may be a foldable device (e.g., the electronic device (200) of FIG. 2b) as described below in FIG. 2a, but this is exemplary, and the electronic device (101) may be a non-foldable device. The electronic device (101) of FIG. 2a may differ from the electronic device (200) of FIG. 2b only in that it is non-foldable. The folding-related embodiment of the electronic device (200) of FIG. 2b may not be applied to the electronic device (101) of FIG. 2a. The remaining embodiments, except for the folding-related embodiment of the electronic device (200) of FIG. 2b, may be applied to the electronic device (101) of FIG. 2a. Hereinafter, for convenience of explanation, the electronic device (101) of FIG. 2a and the electronic device (200) of FIG. 2b will be described only once in the overlapping range, and the differences between the electronic device (101) of FIG. 2a and the electronic device (200) of FIG. 2b will be described for each device.

[0063] FIG. 2B is a diagram illustrating a front, side, and back view of an electronic device including a foldable display according to one embodiment.

[0064] In one embodiment, the electronic device (200) of FIG. 2B may be the electronic device (101) of FIG. 1 or a device similar to the electronic device (101) of FIG. 1. The electronic device (200) of FIG. 2B may include components that are identical or similar to those of the electronic device (101) of FIG. 1. The operation of the electronic device (200) of FIG. 2B may be understood as the operation of the electronic device (101) of FIG. 1 (e.g., components of the electronic device (101) of FIG. 1). For example, the electronic device (200) may be, but is not limited to, a notebook computer, a tablet, a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, or a home appliance device.

[0065] In one embodiment, referring to FIG. 2B, the electronic device (200) may include a foldable housing (201; 202), and a display module (160) (e.g., a foldable display (230)) disposed within a space formed by the foldable housing (201; 202). In the embodiment of FIG. 2B, at least a portion of the display module (160) may be flexible or foldable. For example, the display module (160) may include a foldable display (230). The foldable display (230) may include a plurality of regions (231; 232; 233; 234; 235). The surface on which the foldable display (230) is disposed (or the surface on which the foldable display (230) is visible from the outside of the electronic device (200)) may be defined as the front surface of the electronic device (200). The opposite side of the front surface can be defined as the back surface (221; 222; 223; 224) of the electronic device (200). The surface surrounding the space between the front and back surfaces (221; 222; 223; 224) can be defined as the side surfaces (211; 212; 213; 214; 215; 216) of the electronic device (200).

[0066] According to one embodiment, the foldable housing (201; 202) may include a first housing (201), a second housing (202), a first rear cover (221; 222), a second rear cover (223; 224), and a hinge (or hinge structure) (e.g., a hinge (400) of FIGS. 4A and 4B described below). The foldable housing (201; 202) of the electronic device (200) is not limited to the shape and combination illustrated in FIG. 2B, and may be implemented by a combination and / or combination of other shapes or parts. For example, the first housing (201) and the first rear cover (221; 222) may be formed integrally, and the second housing (202) and the second rear cover (223; 224) may be formed integrally.

[0067] According to one embodiment, the first housing (201) may be connected to a hinge (e.g., hinge (400) of FIGS. 4A and 4B described below). The first housing (201) may include a first side facing in a first direction and a second side facing in a second direction opposite to the first direction. The second housing (202) may be connected to a hinge (e.g., hinge (400) of FIGS. 4A and 4B described below). The second housing (202) may include a third side facing in a third direction and a fourth side facing in a fourth direction opposite to the second direction.

[0068] According to one embodiment, the first housing (201) can rotate relative to the second housing (202) about a hinge (e.g., hinge (400) of FIGS. 4A and 4B described below) (or a first axis (A-A') (e.g., folding axis)). Accordingly, the state of the electronic device (200) can be switched between a folded state and an unfolded state. For example, the state of the hinge (e.g., hinge (400) of FIGS. 4A and 4B described below) of the electronic device (200) can be switched between a folded state and an unfolded state. For example, when the hinge of the electronic device (200) (e.g., the hinge (400) of FIGS. 4A and 4B described below) is folded, the first direction in which the first surface of the first housing (201) faces may be substantially the opposite direction to the third direction in which the third surface of the second housing (202) faces. When the hinge of the electronic device (200) (e.g., the hinge (400) of FIGS. 4A and 4B described below) is unfolded, the first direction may be substantially the same as the third direction. Here, the direction may mean a normal direction of the surface, but is not limited thereto.

[0069] According to one embodiment, the first housing (201) and the second housing (202) may be arranged on both sides with respect to the first axis (A-A') (e.g., the folding axis). As described below, the angle or distance between the first housing (201) and the second housing (202) may vary depending on whether the state of the electronic device (200) is an unfolded state, a folded state, or a partially unfolded (or partially folded) intermediate state. For example, the unfolded state may be defined as 180 degrees, the folded state may be defined as 0 degrees, and the intermediate state may be defined as more than 0 degrees and less than 180 degrees. For example, the unfolded state may be defined as 180 degrees to a first angle (e.g., 170 degrees), the folded state may be defined as 0 degrees to a second angle (e.g., 10 degrees), and the intermediate state may be defined as the second angle (e.g., 10 degrees) to a first angle (e.g., 170 degrees). The angular ranges of the unfolded state, folded state, and intermediate state are not limited thereto.

[0070] According to one embodiment, at least a portion of the first housing (201) and the second housing (202) may be formed of a metallic or non-metallic material having a rigidity of a size selected to support the foldable display (230). At least a portion formed of the metallic material may provide a ground plane of the electronic device (200) and may be electrically connected to a ground line formed on a printed circuit board.

[0071] According to one embodiment, one or more components or sensors may be positioned or visually exposed on the rear surface (221; 222; 223; 224) of the electronic device (200). For example, sensors exposed through the rear surface (221; 222; 223; 224) may include a proximity sensor or a rear camera.

[0072] According to one embodiment, the foldable display (230) may be placed on a space formed by the foldable housing (201; 202). For example, the foldable display (230) may be placed on a recess formed by the foldable housing (201; 202) and may constitute a majority of the front surface of the electronic device (200). For example, the first housing (201) and the second housing (202) of the foldable housing (201; 202) may together form a recess that accommodates the foldable display (230).

[0075] According to one embodiment, the foldable display (230) may refer to a display module in which at least a portion of the area can be transformed into a flat or curved surface. For example, the foldable display (230) may include a foldable area (235), an area (e.g., an upper first area (231) and a lower second area (232) based on the second axis (B-B')) disposed on one side (e.g., a left side of the foldable area (235) illustrated in FIG. 2B) relative to the foldable area (235), and an area (e.g., an upper third area (233) and a lower fourth area (234) based on the second axis (B-B')) disposed on the other side (e.g., a right side of the foldable area (235) illustrated in FIG. 2B) relative to the foldable area (235). For example, in FIG. 2B, the foldable display (230) may include a foldable area (235) located in the center, a first area (231) located on the upper left, a second area (232) located on the lower left, a third area (233) located on the upper right, and a fourth area (234) located on the lower right. The left, right, upper, lower, upper left, lower left, upper right, and lower right are defined based on FIG. 2B, and the positions of the multiple areas (231; 232; 233; 234; 235) of the foldable display (230) may be defined differently depending on the rotation of the electronic device (200).

[0076] According to one embodiment, the foldable region (235) of the foldable display (230) may correspond to a region where a hinge (e.g., hinge (400) of FIGS. 4A and 4B described below) is located. The foldable region (235) may be closed in response to the hinge (e.g., hinge (400) of FIGS. 4A and 4B described below) being closed, and may be unfolded in response to the hinge being unfolded.

[0077] Meanwhile, the division of regions of the foldable display (230) illustrated in FIG. 2B is exemplary, and the foldable display (230) may be divided into multiple regions (e.g., 6 or more or 4 or less) depending on its structure or function. In addition, the multiple regions (231; 232; 233; 234; 235) of the foldable display (230) are regions logically distinguished for the convenience of explanation, and may not be regions separated by hardware.

[0078] According to one embodiment, the sides (211; 212; 213; 214; 215; 216) of the electronic device (200) may include a first side (211), a second side (212), a third side (213), a fourth side (214), a fifth side (215), and a sixth side (216). The first side (211), the fifth side (215), and the sixth side (216) may be sides of the first housing (201). The second side (212), the third side (213), and the fourth side (214) may be sides of the second housing (202). The first side (211) and the second side (212) may form one side. The first side (211) and the second side (212) can be distinguished based on the first axis (A-A') (e.g., folding axis). The fourth side (214) and the fifth side (215) can form one side. The fourth side (214) and the fifth side (215) can be distinguished based on the first axis (A-A') (e.g., folding axis). The third side (213) can be one side that is not distinguished. The sixth side (216) can be one side that is not distinguished.

[0079] FIG. 3 is a drawing illustrating a folding state of an electronic device according to one embodiment.

[0080] FIG. 3(a) shows the electronic device (200) in an unfolded state. FIG. 3(b) and (c) show the electronic device (200) in an intermediate state, partially unfolded (or partially folded). FIG. 3(b) shows the electronic device (200) in the intermediate state being arranged horizontally. FIG. 3(c) shows the electronic device (200) in the intermediate state being arranged vertically. Horizontal and vertical may be defined differently, but according to one embodiment, a state in which a portion of the rear surface of the electronic device (200) is arranged substantially parallel to the ground surface may be defined as a state in which the electronic device (200) is placed vertically. For example, a state in which the first axis (A-A') (e.g., folding axis) of FIG. 2(b) is arranged substantially parallel to the ground surface may be defined as a vertical state of the electronic device (200) or a state in which the electronic device (200) is arranged vertically.

[0081] FIG. 4A is a diagram illustrating an unfolded state of an electronic device according to one embodiment. FIG. 4B is a diagram illustrating a folded state of an electronic device according to one embodiment. FIGS. 4A and 4B are schematic cross-sectional views illustrating an electronic device (200) cut along a second axis (BB`) of the electronic device (200) illustrated in FIG. 2B.

[0082] According to one embodiment, the electronic device (200) can determine whether the electronic device (200) is in an unfolded or folded state by using at least one sensor (e.g., the sensor module (176) of FIG. 1). For example, the at least one sensor (e.g., the sensor module (176) of FIG. 1) may include at least one of an angle sensor, a distance sensor, a gyro sensor, or a Hall sensor. For example, the electronic device (200) can determine whether the state of the electronic device (200) is in an unfolded or folded state by using an inclination, acceleration, gravity, and a distance between the first housing (201) and the second housing (202) of the foldable housing (201; 202) provided in the electronic device (200) for at least one housing of the electronic device (200) detected by the at least one sensor (e.g., the sensor module (176) of FIG. 1). For example, the electronic device (200) can determine whether the state of the electronic device (200) is in the unfolded or folded state by using the unfolded or folded state of the hinge structure (e.g., the hinge (400) or the hinge structure including the hinge (400)) detected by at least one sensor (e.g., the sensor module (176) of FIG. 1). For example, the electronic device (200) can determine whether the state of the electronic device (200) is in the unfolded or folded state by using the rotational direction or rotational angle of at least one hinge structure (e.g., the hinge (400) or the hinge structure including the hinge (400)) provided in the electronic device (200) detected by at least one sensor (e.g., the sensor module (176) of FIG. 1).

[0083] In FIG. 4A, a hinge structure (e.g., hinge (400) or a hinge structure including hinge (400)) is exemplarily illustrated in an unfolded state. For convenience of explanation, the folding angle when the hinge structure (e.g., hinge (400) or a hinge structure including hinge (400)) is fully unfolded may be defined as 180 degrees. However, this is for convenience of explanation, and the folding angle when the hinge structure (e.g., hinge (400) or a hinge structure including hinge (400)) is fully unfolded may also be defined as 0 degrees. According to one embodiment, when the hinge structure (e.g., hinge (400) or a hinge structure including hinge (400)) is unfolded, the foldable display (e.g., foldable display (230) of FIG. 2B) may substantially form one plane.

[0084] FIG. 4B exemplarily illustrates a state in which a hinge structure (e.g., a hinge (400) or a hinge structure including a hinge (400)) is folded. For example, FIG. 4B exemplarily illustrates a state in which a first side of a first housing (201) and a third side of a second housing (202) are arranged to face each other in a folded state of a hinge structure (e.g., a hinge (400) or a hinge structure including a hinge (400)). According to one embodiment, when a hinge structure (e.g., a hinge (400) or a hinge structure including a hinge (400)) is folded, some areas (e.g., 231, 232) of a foldable display (e.g., a foldable display (230) of FIG. 2B) may be arranged to face each other in other areas (e.g., 233, 234).

[0085] In this document, when an electronic device (e.g., an electronic device (101) of FIG. 1, an electronic device (101) of FIG. 2A, or an electronic device (200) of FIG. 2B) performs a specific operation, it may mean that various hardware included in the electronic device (e.g., an electronic device (101) of FIG. 1, an electronic device (101) of FIG. 2A, or an electronic device (200) of FIG. 2B), for example, a processor (120) such as a micro controlling unit (MCU), a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), a microprocessor, or an application processor (AP), performs the specific operation. When an electronic device (e.g., an electronic device (101) of FIG. 1, an electronic device (101) of FIG. 2A, or an electronic device (200) of FIG. 2B) performs a specific operation, it may mean that the processor (120) controls other hardware to perform the specific operation. An electronic device (e.g., an electronic device (101) of FIG. 1, an electronic device (101) of FIG. 2A, or an electronic device (200) of FIG. 2B) performing a specific operation may mean that at least one instruction for performing the specific operation stored in a storage circuit (e.g., a memory (130)) of the electronic device (e.g., an electronic device (101) of FIG. 1, an electronic device (101) of FIG. 2A, or an electronic device (200) of FIG. 2B) is executed, thereby causing the processor (120) or other hardware to perform the specific operation. At least one instruction stored in a memory (130) of an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (101) of FIG. 2A, or the electronic device (200) of FIG. 2B) may, when executed by a processor (120), cause the electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (101) of FIG. 2A, or the electronic device (200) of FIG. 2B) to perform at least one operation.

[0086] Hereinafter, the electronic device (101) of FIG. 1, the electronic device (101) of FIG. 2a, and the electronic device (200) of FIG. 2b will be referred to as electronic devices (101; 200).

An electronic device (101; 200) (e.g., processor (120)) can set a power saving level (or a unit of a power saving level, e.g., a power saving stage)). For example, the electronic device (101; 200) (e.g., processor (120)) can automatically determine a power saving level (or a unit of a power saving level, e.g., a power saving stage) as shown in FIG. 6, or can determine a power saving level (or a unit of a power saving level, e.g., a power saving stage) based on a user input as shown in FIG. 7.

[0091] Let us explain in detail with reference to Fig. 5.

[0092] According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) may perform a power saving operation on power saving areas (e.g., 1 to 25 of (a) of FIG. 8 or 1 to 100 of (b) of FIG. 8) of the display (260; 230) (or the screen of the display (260; 230)) based on the configuration (e.g., 501, 511, 512, 513, 514, 521, 522, 523, 524, 531, 532, 533, 534, 541) of FIG. 8. The power saving areas may be areas of the display (260; 230) (or the screen of the display (260; 230)) for performing the power saving operation. The performance of the power saving operation may be the application of a power saving effect. According to one embodiment, the electronic device (101; 200) (e.g., the processor (120)) may perform the power saving operation on each power saving region (respectively). For example, as described below, the electronic device (101; 200) (e.g., the processor (120)) may set power saving levels (e.g., the power saving levels described in FIG. 9) corresponding to the power saving regions, and display the screen of the display (260; 230) based on the set power saving levels.

[0093] According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) may include a system (501). The system (501) may be a part of the components of FIG. 1. For example, the system (501) may include a display (260; 230). For example, the system (501) may include a battery (189). For example, the system (501) may include an input module (150) (e.g., a microphone, a mouse, a keyboard, keys (e.g., buttons), a digital pen (e.g., a stylus pen), or a touch input device). The electronic device (101; 200) (e.g., processor (120)) may detect an event occurring in the system (501).

[0094] According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) can detect a user input (e.g., input of a mouse, pen, or touch). The electronic device (101; 200) (e.g., processor (120)) can identify an input detection event (e.g., an event of a mouse, pen, or touch) that detects the user input. The electronic device (101; 200) (e.g., processor (120)) can identify the input detection event using the input device detection module (511). For example, the electronic device (101; 200) (e.g., processor (120)) can identify a mouse movement event. For example, the electronic device (101; 200) (e.g., processor (120)) can identify a mouse button click event. For example, the electronic device (101; 200) (e.g., processor (120)) can identify a pen movement event. For example, the electronic device (101; 200) (e.g., processor (120)) can check a pen click event. For example, the electronic device (101; 200) (e.g., processor (120)) can check a touch event. The electronic device (101; 200) (e.g., processor (120)) can provide information corresponding to an input detection event (e.g., coordinate information (e.g., x-coordinate and y-coordinate of the display (260; 230))) to the area change detection module (533). For example, the electronic device (101; 200) (e.g., processor (120)) can check information corresponding to a mouse movement event (e.g., coordinate information). For example, the electronic device (101; 200) (e.g., processor (120)) can check information corresponding to a mouse button click event (e.g., coordinate information and button type information). For example, an electronic device (101; 200) (e.g., processor (120)) can check information (e.g., coordinate information) corresponding to a pen movement event.For example, an electronic device (101; 200) (e.g., processor (120)) can check information (e.g., coordinate information) corresponding to a pen click event. For example, an electronic device (101; 200) (e.g., processor (120)) can check information (e.g., coordinate information) corresponding to a touch event.

[0095] According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) can check an activated application. The electronic device (101; 200) (e.g., processor (120)) can detect an application that is activated and displayed at the top of the screen among the running applications. The electronic device (101; 200) (e.g., processor (120)) can detect an area where the execution screen of the activated application is displayed. The electronic device (101; 200) (e.g., processor (120)) can check an activation event that detects an area where the execution screen of the activated application is displayed. The electronic device (101; 200) (e.g., processor (120)) can check the activation event using the activation app monitor module (512). For example, the electronic device (101; 200) (e.g., processor (120)) can check a list of running applications. For example, the electronic device (101; 200) (e.g., processor (120)) can check a change in a currently activated application. The electronic device (101; 200) (e.g., processor (120)) can provide information corresponding to the activation event (e.g., application information and coordinate information) to the screen layer control module (532). For example, the electronic device (101; 200) (e.g., processor (120)) can check information of a previously activated application. For example, the electronic device (101; 200) (e.g., processor (120)) can check information of a currently activated application.

For example, an electronic device (101; 200) (e.g., processor (120)) can check coordinate information of the execution screen of a currently activated application.

[0096] According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) can check the status of the battery (189) (e.g., whether it is being charged, charge amount). The electronic device (101; 200) (e.g., processor (120)) can check the status of the battery (189) using the battery status detection module (513). For example, the electronic device (101; 200) (e.g., processor (120)) can check a charging event indicating that the battery (189) is being charged. For example, the electronic device (101; 200) (e.g., processor (120)) can check the charge amount of the battery (189). The charge amount of the battery (189) can be a ratio of the current charge capacity to the maximum charge capacity of the battery (189) and / or the current charge capacity. An electronic device (101; 200) (e.g., processor (120)) may provide information (e.g., whether power is connected, current battery charge level) corresponding to the state of the battery (189) (e.g., whether charging, charge level) to a power saving area optimization module (521), a change detection frequency optimization module (522), and / or a power saving level optimization module (523).

[0097] According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) can check the consumption rate of the battery (189). The consumption rate may be a change in capacity per unit time of the battery (189) and / or a ratio of a change in capacity per unit time to a current charge capacity. The electronic device (101; 200) (e.g., processor (120)) can check the consumption rate of the battery (189) using a battery consumption rate detection module (514). The electronic device (101; 200) (e.g., processor (120)) can provide information corresponding to the consumption rate of the battery (189) to a power saving area optimization module (521), a change detection frequency optimization module (522), and / or a power saving level optimization module (523).

[0098] According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) may adjust the division unit of the power saving area (e.g., horizontal number and / or vertical number), the detection frequency of screen change, and / or the power saving level (or unit of the power saving level) according to conditions. For example, the electronic device (101; 200) (e.g., processor (120)) may adjust the division unit of the power saving area (e.g., the number of power saving areas (e.g., 5x5 or 10x10)) according to conditions. For example, the electronic device (101; 200) (e.g., processor (120)) may adjust the detection frequency of the screen change (e.g., checking for a screen change every second or checking for a screen change every 3 seconds) according to conditions. For example, the electronic device (101; 200) (e.g., processor (120)) can adjust the power saving level (or the unit of the power saving level) (e.g., 0% and 100% or 0%, 50%, and 100%) according to conditions. For example, the electronic device (101; 200) (e.g., processor (120)) can adjust the unit of division of the power saving area (e.g., number of horizontal lines, number of vertical lines), the detection frequency of screen changes, and / or the power saving level (or the unit of the power saving level) based on the charge amount and consumption rate of the battery (189). For example, the electronic device (101; 200) (e.g., processor (120)) can adjust the unit of division of the power saving area (e.g., number of horizontal lines, number of vertical lines), the detection frequency of screen changes, and / or the power saving level (or the unit of the power saving level) based on a first weight of the charge amount of the battery (189) and a second weight of the consumption rate.

[0099] When the number of power-saving areas is small, as in (a) of Fig. 8, the size of each power-saving area increases. When the number of power-saving areas is large, as in (b) of Fig. 8, the size of each power-saving area decreases.

[0100] According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) can reduce the consumption of the battery (189) by adjusting the number of power-saving regions based on the state of the battery (189) (e.g., charging event, charge amount) and the consumption rate of the battery (189). The electronic device (101; 200) (e.g., processor (120)) can adjust the number of power-saving regions based on the state of the battery (189) (e.g., charging event, charge amount) and the consumption rate of the battery (189) by using the power-saving region optimization module (521). FIG. 8 (a) illustrates an embodiment in which the horizontal number of power-saving regions is 5 and the vertical number of power-saving regions is 5, and FIG. 8 (b) illustrates an embodiment in which the horizontal number of power-saving regions is 10 and the vertical number of power-saving regions is 10. For example, the electronic device (101; 200) (e.g., processor (120)) can adjust the number of power-saving areas (e.g., horizontal number and / or vertical number) according to Equation 1 and / or Equation 2 based on a weight of the charge amount of the battery (189) and a weight of the consumption rate of the battery (189).

[0101] (Mathematical Formula 1) Number of horizontal lines = Maximum number of horizontal lines * (a1 * charge amount + b1 * consumption rate)

[0102] (Mathematical formula 2) Vertical number = Maximum vertical number * (a2 * charge amount + b2 * consumption rate)

[0103] For example, the weights (e.g., a1 and / or a2) of the charge amount of the battery (189) may have a value between a minimum value (e.g., 0 or 0.1) and a maximum value (e.g., 1 or 0.9). For example, the weights (e.g., a1 and / or a2) of the charge amount of the battery (189) may be inversely proportional to the charge amount of the battery (189). The values ​​of the weights (e.g., a1 and / or a2) of the charge amount of the battery (189) are exemplary only and there is no limitation to the values.

[0104] For example, the weights (e.g., b1 and / or b2) of the consumption rate of the battery (189) may have a value between a minimum value (e.g., 0 or 0.1) and a maximum value (e.g., 1 or 0.9). For example, the weights (e.g., b1 and / or b2) of the consumption rate of the battery (189) may be proportional to the consumption rate of the battery (189). The values ​​of the weights (e.g., b1 and / or b2) of the consumption rate of the battery (189) are exemplary only and there is no limitation to the values.

[0105] For example, when the battery (189) has a low charge and a high consumption rate, the number of power-saving areas may be close to the maximum, and when the battery has a high charge and a low consumption rate, the number of power-saving areas may be reduced.

[0106] According to one embodiment, the sizes of the first power-saving areas (e.g., (a) of FIG. 8) of the display (260; 230) as power-saving areas are illustrated as being set to the same size, but the sizes of the first power-saving areas (e.g., (a) of FIG. 8) may be set to at least some different sizes. For example, the electronic device (101; 200) (e.g., processor (120)) may adjust the number of power-saving areas by including at least some power-saving areas of different sizes based on the status of the battery (189) (e.g., charging event, amount of charge) and the consumption rate of the battery (189).

[0107] According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) can reduce the consumption of the battery (189) by adjusting the detection frequency of screen changes (e.g., checking for screen changes every second or every three seconds) based on the status of the battery (189) (e.g., charging event, charge amount) and the consumption rate of the battery (189). The electronic device (101; 200) (e.g., processor (120)) can adjust the detection frequency of screen changes based on the status of the battery (189) (e.g., charging event, charge amount) and the consumption rate of the battery (189) using the change detection frequency optimization module (522). The screen change may be a change in the content displayed on a portion of an area of ​​the screen displayed on the display (260; 230). Detection of a screen change may be detecting an area (e.g., power-saving areas) of the display (260; 230) in which the content displayed on the screen changes. According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) may determine whether a screen change in a power-saving area is detected based on the ratio of an area in which the content displayed on the screen changes in one power-saving area. For example, the electronic device (101; 200) (e.g., processor (120)) may detect a screen change in the power-saving area when the ratio of an area in which the content displayed on the screen changes in one power-saving area is greater than or equal to a reference value (e.g., when an area in which the content displayed on the screen changes in the power-saving area is significantly large). According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) may determine whether a screen change in the power-saving area is detected regardless of the ratio of an area in which the content displayed on the screen changes in one power-saving area. For example, an electronic device (101; 200) (e.g., processor (120)) may detect a change in the screen of a power-saving area based on a change in the content displayed on the screen, even partially, in that power-saving area.Detection of a screen change in the corresponding power saving area can be referred to as confirmation of a screen change event in the corresponding power saving area. The frequency of detecting a screen change may be the frequency of determining whether a screen has changed. For example, the electronic device (101; 200) (e.g., processor (120)) may check for a screen change every second or every three seconds, but this is exemplary. According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) may adjust the frequency of detecting a screen change according to mathematical expression 3 based on a weighted value of the charge amount of the battery (189) and a weighted value of the consumption rate of the battery (189).

[0108] (Mathematical Formula 3) Detection Frequency = Basic Detection Frequency + Additional Delay Frequency * (a3 * Charge Amount + b3 * Consumption Rate)

[0109] The basic detection frequency may be a value set as a basic time unit for detecting screen changes. The additional delay frequency may be a value for adjusting the detection frequency of screen changes according to the charge level and consumption rate of the battery (189).

[0110] For example, the weight (e.g., a3) of the charge amount of the battery (189) can have a value between a minimum value (e.g., 0 or 0.1) and a maximum value (e.g., 1 or 0.9). For example, the weight (e.g., a3) of the charge amount of the battery (189) can be proportional to the charge amount of the battery (189). The value of the weight (e.g., a3) of the charge amount of the battery (189) is only exemplary and there is no limitation to the value.

[0111] For example, the weight (e.g., b3) of the consumption rate of the battery (189) may have a value between a minimum value (e.g., 0 or 0.1) and a maximum value (e.g., 1 or 0.9). For example, the weight (e.g., b3) of the consumption rate of the battery (189) may be inversely proportional to the consumption rate of the battery (189). The value of the weight (e.g., b3) of the consumption rate of the battery (189) is only exemplary and there is no limitation to the value.

[0112] For example, when the battery (189) has a low charge and a high consumption rate, the frequency of detecting screen changes may decrease, and when the battery has a high charge and a low consumption rate, the frequency of detecting screen changes may increase.

[0113] According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) can reduce the consumption of the battery (189) by adjusting the power saving level (or the unit of the power saving level) based on the state of the battery (189) (e.g., charging event, charge amount) and the consumption rate of the battery (189). The electronic device (101; 200) (e.g., processor (120)) can adjust the power saving level (or the unit of the power saving level) based on the state of the battery (189) (e.g., charging event, charge amount) and the consumption rate of the battery (189) using the power saving level optimization module (523). The power saving level may be a level for applying a power saving effect. The power saving level may have a value between the minimum power saving level and the maximum power saving level. The unit of the power saving level may be the number of power saving levels including the minimum power saving level and the maximum power saving level. For example, if the minimum power saving level corresponds to 0% power saving effect, the highest power saving level corresponds to 100% power saving effect, and there is no other power saving level between the minimum power saving level and the highest power saving level, the unit of the power saving level may be 2 (or 2 steps). For example, if the minimum power saving level corresponds to 0% power saving effect, the highest power saving level corresponds to 100% power saving effect, and there is one power saving level (e.g., a power saving level corresponding to 50%) between the minimum power saving level and the highest power saving level, the unit of the power saving level may be 3 (or 3 steps). According to one embodiment, the electronic device (101; 200) (e.g., the processor (120)) may adjust the power saving level (or the unit of the power saving level) according to Equation 4 based on a weighted value of the charge amount of the battery (189) and a weighted value of the consumption rate of the battery (189). The unit of power saving level can be called power saving stage.

[0114] (Mathematical Formula 4) Power saving stage = maximum stage * (a4 * charge amount + b4 * consumption rate)

[0115] For example, the weight of the charge amount of the battery (189) (e.g., a4) can have a value between a minimum value (e.g., 0 or 0.1) and a maximum value (e.g., 1 or 0.9). For example, the weight of the charge amount of the battery (189) (e.g., a4) can be proportional to the charge amount of the battery (189). The value of the weight of the charge amount of the battery (189) (e.g., a4) is only exemplary and there is no limitation to the value.

[0116] For example, the weight (e.g., b4) of the consumption rate of the battery (189) may have a value between a minimum value (e.g., 0 or 0.1) and a maximum value (e.g., 1 or 0.9). For example, the weight (e.g., b4) of the consumption rate of the battery (189) may be inversely proportional to the consumption rate of the battery (189). The value of the weight (e.g., b4) of the consumption rate of the battery (189) is only exemplary and there is no limitation to the value.

[0117] For example, when the battery (189) has a high charge and a low consumption rate, the power saving stage is close to the maximum, and when the charge is low and the consumption rate is high, the power saving stage may be reduced. When the power saving stage according to mathematical expression 4 is 2 or less, the electronic device (101; 200) (e.g., processor (120)) may determine the power saving stage (e.g., unit of power saving level) to be 2 (e.g., 2 stages including a minimum power saving level and a maximum power saving level).

[0118] According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) may set an "exclusion area" to which power saving effects are not applied. For example, when a user displays a lecture video and lecture document materials on the screen, the user may want the power saving effect not to be applied to the area where the lecture document materials are displayed. The electronic device (101; 200) (e.g., processor (120)) may set the exclusion area based on user input. The electronic device (101; 200) (e.g., processor (120)) may not apply the power saving effect to an area that is in contact with the exclusion area among the power saving areas of the display (260; 230). An electronic device (101; 200) (e.g., processor (120)) may not apply a power saving effect to an area that is adjacent to an excluded area among the power saving areas of a display (260; 230) by using a power saving effect non-application area management module (524).

[0119] According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) can set a power saving area of ​​the display (260; 230). For example, the electronic device (101; 200) (e.g., processor (120)) can set a power saving area having a horizontal number of 5 and a vertical number of 5, as shown in (a) of FIG. 8. The horizontal number and the vertical number of the power saving area may be different. The electronic device (101; 200) (e.g., processor (120)) can change the power saving area of ​​the display (260; 230). For example, the electronic device (101; 200) (e.g., processor (120)) can change the power saving area of ​​the display (260; 230) from 5x5 of (a) of FIG. 8 to 10x10 of (b) of FIG. For example, an electronic device (101; 200) (e.g., processor (120)) can change a power saving area using a power saving area arrangement module (531) in response to a request for changing the number of power saving areas.

[0120] According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) may configure layers of a screen to be displayed on the display (260; 230). For example, the screen may be configured as a combination of multiple layers. The electronic device (101; 200) (e.g., processor (120)) may reduce power consumption by distinguishing layers of the display (260; 230) (or the screen to be displayed on the display (260; 230)). According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) may determine the configuration of the screen layers based on the mode of the currently activated application (e.g., normal mode or full mode). The full mode may be a mode in which the execution screen of the currently activated application is displayed in a full screen mode. The normal mode may be a mode in which the execution screen of the currently activated application is displayed in a window mode smaller than the full screen. For example, as shown in FIG. 10, when the mode of the currently activated application is the normal mode, the electronic device (101; 200) (e.g., processor (120)) may configure the layers of the display (260; 230) (or the screen to be displayed on the display (260; 230)) as, in order from the top, an input detection layer (1010), an activation layer (1020), an exclusion layer (1030), a power saving layer (1040), a deactivation layer (1050), and a desktop layer (1060). For example, as shown in FIG. 11, when the mode of the currently activated application is full mode, the electronic device (101; 200) (e.g., processor (120)) may configure the layers of the display (260; 230) (or the screen to be displayed on the display (260; 230)) as, in order from the top, an input detection layer (1110), an exclusion layer (1120), a power saving layer (1130), an activation layer (1140), a deactivation layer (1150), and a desktop layer (1160).The input detection layer (1010, 1110) may be a transparent layer for checking an input detection event. The activation layer (1020, 1140) may be a layer where the execution screen of the currently activated application is located. The exclusion layer (1030, 1120) may be a transparent layer in which an exclusion area to which no power-saving effect is applied is designated. The power-saving layer (1040, 1130) may be a layer in which the power-saving level of each power-saving area is adjusted according to an event, and a power-saving effect corresponding to the power-saving level is applied. The deactivation layer (1050, 1150) may be a layer where the execution screens of the remaining applications excluding the activated application are located. The desktop layer (1060, 1160) may be a layer where the default desktop is located.

[0121] According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) can detect a screen change. The electronic device (101; 200) (e.g., processor (120)) can detect a screen change using an area change detection module (533). The electronic device (101; 200) (e.g., processor (120)) can detect screen changes (e.g., screen change events) of power-saving areas respectively (respectively) based on a detection frequency. The electronic device (101; 200) (e.g., processor (120)) may not apply a power-saving effect to a power-saving area that is in contact with an exclusion area. The electronic device (101; 200) (e.g., processor (120)) can provide information corresponding to a screen change event to the region power saving module (541). The electronic device (101; 200) (e.g., processor (120)) can obtain region information (e.g., information on an excluded region) set from the power saving effect non-application region management module (524) and provide related information to the region power saving module (541) so as not to apply a power saving effect to a power saving region that contacts the excluded region even if a screen change is not detected. The electronic device (101; 200) (e.g., processor (120)) can adjust the power saving level of the power saving region corresponding to the location where the input detection event occurred. The electronic device (101; 200) (e.g., processor (120)) can provide related information to the region power saving module (541) corresponding to the location where the input detection event occurred based on confirmation of the input detection event.

[0122] In one embodiment, the electronic device (101; 200) (e.g., processor (120)) can adjust power saving levels corresponding to power saving regions. The electronic device (101; 200) (e.g., processor (120)) can manage the power saving levels using a region power saving level change module (534).

[0123] According to one embodiment, the electronic device (101; 200) (e.g., processor (120)) may display a screen based on a power saving level. The electronic device (101; 200) (e.g., processor (120)) may provide information about the power saving level to the region power saving module (541). The electronic device (101; 200) (e.g., processor (120)) may change the power saving level based on a request for a change in the power saving effect (e.g., change in the power saving level) and display a screen based on the changed power saving level. The electronic device (101; 200) (e.g., processor (120)) may divide the power saving areas based on the horizontal number and vertical number of the power saving areas, and may place the region power saving module (541) at the location of each area. The electronic device (101; 200) (e.g., processor (120)) applies a power saving effect by combining transparency and black according to a power saving level. For example, 910 of FIG. 9 may be a 0% power saving effect (e.g., no power saving effect or transparent application) corresponding to a minimum power saving level. For example, 920 of FIG. 9 may be a 50% power saving effect (e.g., semi-transparent black application) corresponding to a medium power saving level. For example, 930 of FIG. 9 may be a 100% power saving effect (e.g., black application) corresponding to a maximum power saving level. The power saving effects (e.g., 0%, 50%, 100%) corresponding to power saving levels (e.g., minimum power saving level, medium power saving level, and maximum power saving level, or first power saving level, second power saving level, third power saving level, and fourth power saving level) are not limited to the above-described embodiments. According to one embodiment, a power saving effect corresponding to a power saving level can be determined based on the ambient illuminance value of the electronic device (101; 200).According to one embodiment, the value of the power saving effect in a state where the brightness value of the display (260; 230) is determined according to the ambient illuminance value of the electronic device (101; 200) (e.g., auto brightness) and the value of the power saving effect in a state where the brightness value of the display (260; 230) is determined regardless of the ambient illuminance value of the electronic device (101; 200) (e.g., absolute brightness) may be different. For example, in absolute brightness, the power saving effect corresponding to the intermediate power saving level may be 50% (e.g., applying a translucent black color), and in auto brightness, when the ambient illuminance value of the electronic device (101; 200) is low and the brightness value of the display (260; 230) is low, the power saving effect corresponding to the intermediate power saving level may be 25%, which is lower than 50%.

[0124] The operations of an electronic device (e.g., the electronic device (101) of FIG. 1, the electronic device (101) of FIG. 2A, or the electronic device (200) of FIG. 2B) may be described in detail with reference to the embodiments described above (e.g., the embodiments of FIGS. 1 to 11) and the embodiments described below (e.g., the embodiments of FIGS. 12A, 12B, 13 to 26). Although each embodiment is disclosed in a separate drawing and a separate paragraph, this is merely for convenience of description, and at least some of the embodiments described above and at least some of the embodiments described below may be applied together. At least some of the embodiments described above and at least some of the embodiments described below may be omitted.

[0125] FIG. 12A is a flowchart of a method of operating an electronic device according to one embodiment.

[0126] At least some of the operations of Fig. 12a may be omitted. The order of the operations of Fig. 12a may be changed. Operations other than the operations of Fig. 12a may be performed before, during, or after performing the operations of Fig. 12a.

[0127] Referring to FIG. 12a, an operation of applying different power saving effects to an area corresponding to a screen change event and an area not corresponding to a screen change event among power saving areas can be described.

[0128] Referring to FIG. 12A, in operation 1211, according to one embodiment, the electronic device (101; 200) may set power-saving areas. For example, the electronic device (101; 200) may set power-saving areas in the display (260; 230). For example, the electronic device (101; 200) may set first power-saving areas (e.g., (a) of FIG. 8) in the display (260; 230) as power-saving areas based on a default setting.

[0129] In operation 1213, according to one embodiment, the electronic device (101; 200) can determine whether a screen change event has occurred. The screen change event is an event corresponding to the detection of a change in the screen of a power-saving area, and can be understood with reference to the above-described description. The electronic device (101; 200) can determine an area among the power-saving areas in which a screen change event has occurred and an area in which a screen change event has not occurred.

[0130] In operation 1215, according to one embodiment, the electronic device (101; 200) may apply a first power-saving effect to a first region among the power-saving regions in which a screen change event has occurred. In operation 1217, according to one embodiment, the electronic device (101; 200) may apply a second power-saving effect to a second region among the power-saving regions in which a screen change event has not occurred. For example, the electronic device (101; 200) may apply a first power-saving effect that lowers the power-saving level by one level (e.g., displays the first region brighter than before) to the first region in which a screen change event has occurred. For example, the electronic device (101; 200) may apply a first power-saving effect corresponding to a minimum power-saving level (e.g., displays the first region brightest) to the first region in which a screen change event has occurred. For example, the electronic device (101; 200) may apply a second power-saving effect that increases the power-saving level by one level (e.g., displays the second area darker than before) to a second area where a screen change event has not occurred. For example, the electronic device (101; 200) may apply a second power-saving effect corresponding to the highest power-saving level (e.g., displays the second area darkest) to a second area where a screen change event has not occurred. The descriptions of the first power-saving effect and the second power-saving effect are exemplary, and there are no limitations to the first power-saving effect and the second power-saving effect.

[0131] According to one embodiment, the electronic device (101; 200) may display a screen on the display (260; 230) based on an applied power saving effect (e.g., power saving level).

[0132] FIG. 12b is a flowchart of a method of operating an electronic device according to one embodiment.

[0133] At least some of the operations of Fig. 12b may be omitted. The order of the operations of Fig. 12b may be changed. Operations other than the operations of Fig. 12b may be performed before, during, or after the operations of Fig. 12b.

[0134] Referring to FIG. 12b, an operation of not applying a power saving effect, or changing or maintaining a power saving effect, based on a charging event can be described.

[0135] Referring to FIG. 12b, in operation 1221, according to one embodiment, the electronic device (101; 200) may set first power-saving areas (e.g., (a) of FIG. 8) on the display (260; 230) as power-saving areas, and set first power-saving levels corresponding to the first power-saving areas as power-saving levels.

[0136] In operation 1223, according to one embodiment, the electronic device (101; 200) may display a screen on the display (260; 230) based on the first power saving levels of the first power saving areas.

[0137] In operation 1225, according to one embodiment, the electronic device (101; 200) can determine whether a charging event has occurred. The charging event is an event indicating that the battery (189) of the electronic device (101; 200) is being charged, and can be understood with reference to the above-described description.

[0138] In operation 1227, according to one embodiment, the electronic device (101; 200) may display a screen without applying a power saving effect on the entire area of ​​the display (260; 230) based on the confirmation of a charging event of the battery (189).

[0139] In operation 1229, according to one embodiment, the electronic device (101; 200) may change or maintain the power saving effect based on the charge amount of the battery (189) and the consumption rate of the battery (189) based on whether the charging event of the battery (189) is not confirmed. For example, the electronic device (101; 200) may change or maintain the first power saving levels of the first power saving areas based on the charge amount of the battery (189) and the consumption rate of the battery (189), or may set second power saving areas different from the first power saving areas on the display (260; 230) and set second power saving levels corresponding to the second power saving areas. As described above, for example, the electronic device (101; 200) can change or maintain the power saving effect based on the weight of the charge amount of the battery (189) and the weight of the consumption rate of the battery (189), based on whether the charging event of the battery (189) is not confirmed.

[0140] According to one embodiment, the electronic device (101; 200) can display a screen on the display (260; 230) based on the first power saving levels of the first power saving regions or the second power saving levels of the second power saving regions.

[0141] FIGS. 13 to 26 are drawings illustrating the operation of an electronic device according to one embodiment.

[0142] With reference to FIGS. 8 and 13 to 26, the above-described embodiments (e.g., the embodiments of FIGS. 1 to 12a and 12b) can be described in detail.

[0143] According to one embodiment, the electronic device (101; 200) may set first power saving regions (e.g., 1 to 25 of (a) of FIG. 8) and first power saving levels corresponding to the first power saving regions.

[0144] According to one embodiment, the electronic device (101; 200) may set the power saving level(s) of the region(s) of the display (260; 230) in which the screen change event is not detected to the highest power saving level based on whether a screen change event is not detected for a first period (e.g., a set period). For example, the electronic device (101; 200) may set the first power saving levels of all the first power saving regions of the display (260; 230) to the highest power saving level based on whether a screen change event is not detected for a first period (e.g., a set period). Accordingly, as shown in (a) of FIG. 8, the electronic device (101; 200) may display a black screen on the entire region of the display (260; 230). Displaying a black screen may include not displaying a screen.

[0145] Referring to FIG. 13, according to one embodiment, the electronic device (101; 200) can display a screen in a first area of ​​the display (260; 230) by adjusting a power saving level corresponding to the first area based on confirmation of a screen change event (or activation event) in the first area among the first power saving areas (e.g., 3, 4, 5, 8, 9, 10, 13, 14, and 15 of FIGS. 8 and 13). For example, as shown in FIG. 13, based on whether a screen change event is confirmed on the first screen of the first application located in the first area (e.g., 3, 4, 5, 8, 9, 10, 13, 14, and 15 of FIGS. 8 and 13) or an activation event of the first application is confirmed, the electronic device (101; 200) may adjust the power saving level corresponding to the first area to a second level (e.g., medium power saving level). Accordingly, the electronic device (101; 200) may display the area corresponding to the first screen of the first application at the highest brightness corresponding to the minimum power saving level, and display the area excluding the first screen of the first application in the first area (e.g., 3, 4, 5, 8, 9, 10, 13, 14, and 15 of FIGS. 8 and 13) at the brightness corresponding to the second level (e.g., medium power saving level). For example, the electronic device (101; 200) can apply a power saving effect corresponding to a second level (e.g., an intermediate power saving level) to a first area (e.g., 3, 4, 5, 8, 9, 10, 13, 14, and 15 of FIGS. 8 and 13) of the power saving layer, and configure the screen so that the active layer on which the first screen of the first application is located is located above the power saving layer. At this time, the electronic device (101; 200) can maintain the power saving level corresponding to the second area (e.g., 1, 2, 6, 7, 11, 12, and 16 to 25 of FIGS. 8 and 13) among the first power saving areas that do not respond to a screen change event as the highest power saving level.

[0146] Referring to FIG. 14, according to one embodiment, the electronic device (101; 200) can identify an input detection event that detects a user input in a third area (e.g., 12 and 17 of FIGS. 8 and 14) among the second areas (e.g., 1, 2, 6, 7, 11, 12, and 16 to 25 of FIGS. 8 and 13). The electronic device (101; 200) can display a screen in the third area of ​​the display (260; 230) by adjusting a power saving level corresponding to the third area based on the input detection event in the third area (e.g., 12 and 17 of FIGS. 8 and 14). For example, as shown in FIG. 14, based on the detection of user input (e.g., mouse movement, pen input, or touch input) moving to 9, 8, 13, 12, and 17 of FIG. 8 and FIG. 14, the electronic device (101; 200) can adjust the power saving level corresponding to the third region to a second level (e.g., medium power saving level). Accordingly, the electronic device (101; 200) can display the third region (e.g., 12, 17 of FIG. 8 and FIG. 14) at a brightness corresponding to the second level (e.g., medium power saving level). At this time, the electronic device (101; 200) can maintain the power saving level corresponding to the fourth region (e.g., 1, 2, 6, 7, 11, 16, and 18 to 25 of FIGS. 8 and 14) other than the third region (e.g., 12 and 17 of FIGS. 8 and 14) among the second regions (e.g., 1, 2, 6, 7, 11, 12, and 16 to 25 of FIGS. 8 and 13) at the highest power saving level. At this time, the electronic device (101; 200) can maintain the power saving level corresponding to the first region (e.g., 3, 4, 5, 8, 9, 10, 13, 14, and 15 of FIGS. 8 and 13) at the existing power saving level.
