Description

Technical Field

[0001] This disclosure relates to electronic devices for seamlessly displaying images and methods of operating thereof. Background Technology

[0002] With the development of digital technology, electronic devices are available in various forms, such as smartphones, tablet PCs, or personal digital assistants (PDAs). Electronic devices are evolving into portable or wearable devices to improve user portability and accessibility.

[0003] Recently, portable electronic devices such as smartphones and tablets have become increasingly lighter and thinner for portability and have expanded into many fields for user convenience. In particular, foldable electronic devices equipped with flexible displays offer relatively larger screens than ordinary candybar electronic devices, and their size decreases when folded, making them easy to carry. Therefore, such electronic devices are becoming increasingly popular as they cater to consumer tastes.

[0004] The above information is provided as background information only to aid in understanding this disclosure. No determination or assertion is made as to whether any of the above constitutes prior art with respect to this disclosure. Summary of the Invention

[0005] Technical issues

[0006] A foldable electronic device may include a hinge structure and can enter a folded or unfolded state based on user operation. Depending on the folded or unfolded state, the foldable electronic device may have different display resolutions. Therefore, when changing states between folded and unfolded, the foldable electronic device may require images of different resolutions. However, the time required to render a new image may be longer than the time required to change states between folded and unfolded. Therefore, when changing states between folded and unfolded, the user may experience a delay where no image is displayed on the foldable electronic device's display.

[0007] The present disclosure is intended to at least address the aforementioned problems and / or disadvantages, and to provide at least the following advantages. Therefore, one aspect of the present disclosure provides an electronic device for seamlessly displaying images and a method of operating thereon.

[0008] Technical solution

[0009] Other aspects will be set forth in part in the description which follows, and will be apparent in part from the description, or may be learned by practice of the proposed embodiments.

[0010] According to one aspect of this disclosure, an electronic device is provided. The electronic device includes: a first display disposed on a first surface of the electronic device; a second display disposed on a second surface of the electronic device and having at least a portion invisible to a user depending on the folded state of the electronic device; a memory configured to store instructions; and a processor electrically connected to the first display, the second display, and the memory, the processor being configured to execute the instructions to: detect a change in the folded state of the electronic device when a first image is displayed on one of the first or second displays. For example, the operation can be performed when a predetermined degree (or angle) or greater unfolding or closing operation occurs. When the unfolding degree is less than the predetermined degree, the operation may not be performed. For example, when the folding operation is repeated at high speed, a snapshot image generated by the initial change in folded state may remain unchanged. The processor can: generate a second image to be displayed on the first display or the other of the second displays; while generating the second image, store a snapshot image of the first image in the memory and display the snapshot image on the first display or the other of the second displays; and after the second image is generated, display the second image instead of the snapshot image on the first display or the other of the second displays.

[0011] According to another aspect of this disclosure, an electronic device is provided. The electronic device includes: a display, wherein an area facing a user changes according to a folded state of the electronic device; a memory storing instructions; and a processor electrically connected to the display and the memory. The processor can execute the instructions to: detect a change in the folded state of the electronic device when a first image is displayed on a first area of ​​the display; when the change in folded state is detected, identify a second area of ​​the display corresponding to the changed folded state; generate a second image to be displayed on the identified second area; while generating the second image, store a snapshot image of the first image in the memory and display the snapshot image on the identified second area of ​​the display; and when the second image is generated, display the second image on the identified second area of ​​the display instead of the snapshot image.

[0012] Technical effect

[0013] According to various embodiments, the electronic device and its operating method can take a snapshot of an existing image when the state changes between a folded state and an unfolded state, and can display the snapshot image on a new display area of ​​the display, thereby reducing the user's latency experience.

[0086] In an embodiment, the processor 510 can use a program stored in the memory 540 (e.g., Figure 1 The processor 510 generates images for display on the display 520 using a program 140. In an embodiment, the processor 510 can generate images using an application installed in the electronic device 101. In an embodiment, the processor 510 can generate images at pre-specified intervals. In an embodiment, images generated at pre-specified intervals may be referred to as an image stream.

[0087] In one embodiment, processor 510 may draw images on a layer assigned to an application installed in electronic device 101.

[0090] In an embodiment, the processor 510 may display an image on a display area of ​​a display 520 corresponding to the state of the electronic device 501 (e.g., a folded state or an unfolded state). In an embodiment, the display area of ​​the display 520 may indicate an enabled area within the entire area of ​​the display 520. For example, the entire area of ​​the display 520 may correspond to... Figure 3 The area of ​​the flexible display 340. For example, the entire area of ​​the display 520 can correspond to... Figure 4 The area of ​​the first display 440 and the area of ​​the second display 450.

[0091] In an embodiment, when the electronic device 501 uses an outward folding method and is in an unfolded state, the display area of ​​the display 520 can correspond to the entire area of ​​the display 520 (e.g., Figure 3 The flexible display 340 area). In an embodiment, when the electronic device 501 uses an outward folding method and is in a folded state, the display area of ​​the display 520 may correspond to a specific area of ​​the display 520 (e.g., Figure 3 The first region 341 or the second region 345 of the flexible display 340.

[0092] In an embodiment, when the electronic device 501 uses an inward folding method and is in an unfolded state, the display area of ​​the display 520 may correspond to the first display of the display 520 (e.g., Figure 4 The area of ​​the first display 440). In an embodiment, when the electronic device 501 uses an inward folding method and is in a folded state, the display area of ​​the display 520 may correspond to the area of ​​the second display of the display 520 (e.g., the area of ​​the first display 440). Figure 4 The area of ​​the second display (450).

[0093] In an embodiment, processor 510 may generate instructions to execute an ongoing application (e.g., Figure 1 The processor 510 can generate an image of the result of application 146) and display the generated image on display 520. In an embodiment, the processor 510 can generate an image of a first resolution corresponding to the state of electronic device 501 and corresponding to a first display area of ​​display 520, and can display the image of the first resolution on the first display area of ​​display 520. In an embodiment, when the electronic device is in a first state (e.g., a folded state), the first display area may be a pre-defined display area. In an embodiment, the first resolution may correspond to the resolution of the first display area. In an embodiment, displaying an image on display 520 indicating the result of executing the application may indicate that the application is displayed on display 520.

[0094] In one embodiment, the processor 510 can recognize state changes of the electronic device 501 during the display of an image at a first resolution on a first display area of ​​the display 520.

In another embodiment, the processor 510 can recognize a first state change from a folded state to an unfolded state of the electronic device 501 based on the sensor module 530. In yet another embodiment, the processor 510 can determine the state change of the electronic device 501 from an open state to a folded state by utilizing two or more sensors, based on the sensor module 530. For example, after a touch operation (a grip for folding or unfolding) occurs via a touch sensor, the processor 510 can determine a fully folded or unfolded state by recognizing the progress toward folding or unfolding using an angular velocity sensor.

[0095] In one embodiment, when a change in the state of electronic device 501 is detected, processor 510 may enable (e.g., turn on) a new display area of ​​display 520 corresponding to the changed state of electronic device 501. In another embodiment, when a change in the state of electronic device 501 is detected, processor 510 may deactivate a first display area of ​​display 520. In yet another embodiment, the new display area corresponding to the changed state of electronic device 501 may be a second display area.

[0096] In this embodiment, when a change in the state of the electronic device 501 is detected, the processor 510 can identify the application being displayed on the first display area of ​​the display 520 (e.g., Figure 1 The continuity information (application 146) may be information indicating whether an already displayed application will be displayed when the state of the electronic device 501 changes. In an embodiment, the continuity information may be information indicating whether an already displayed application will be displayed when a first state change occurs in the electronic device 501, and information indicating whether an already displayed application will be displayed when a second state change occurs in the electronic device 501. In an embodiment, for a specific application, the continuity during the first state change and the continuity during the second state change may be set to be the same as or different from each other. For example, for a specific application, the continuity during the first state change and the continuity during the second state change may be set. For example, for a certain application, the continuity during the first state change and the continuity during the second state change may be disabled. For example, for a certain application, the continuity during the first state change may be set, while the continuity during the second state change may be disabled.

[0097] In an embodiment, when a specific state change (e.g., a first state change) is set for a specific application displayed in the folded state of the electronic device 501, the specific application can also be displayed in the second state (e.g., the unfolded state) when the electronic device 501 changes from the first state (e.g., the folded state) to the second state (e.g., the unfolded state).

[0098] In one embodiment, when continuity during a specific state change (e.g., a first state change) is disabled for a specific application displayed in the folded state of the electronic device 501, and when the electronic device 501 changes from the first state (e.g., folded state) to the second state (e.g., unfolded state), the display of the specific application can be stopped. In another embodiment, when continuity during a specific state change (e.g., a first state change) is disabled for all applications displayed in the folded state of the electronic device 501, and when the electronic device 501 changes from the first state (e.g., folded state) to the second state (e.g., unfolded state), the display 520 can be deactivated (e.g., turned off). In yet another embodiment, when continuity during a specific state change (e.g., a first state change) is disabled for all applications displayed in the folded state of the electronic device 501, and when the electronic device 501 changes from the first state (e.g., folded state) to the second state (e.g., unfolded state), the display 520 can display a pre-specified screen (e.g., a home screen, a lock screen).

[0099] In an embodiment, when the continuity of an application being displayed on the first display area of ​​the display 520 is set, the processor 510 can generate a new application indicating that it should run (e.g., Figure 1 An image showing the execution result of application 146. In an embodiment, the image indicates the running application (e.g., ...). Figure 1 The new image resulting from the execution of application 146) can correspond to the resolution of the second display area of ​​display 520. In an embodiment, processor 510 can generate a new image by redrawing a layer on a specific application, a layer on the status bar, a launcher layer, a wallpaper layer, a layer on a notification, or a combination thereof.

[0100] In an embodiment, the processor 510 may display an application indicating its operation (e.g., on a second display area of ​​the display 520) on the display 520. Figure 1 A new image of the execution result of application 146).

[0101] In one embodiment, when a change in the state of the electronic device 501 is detected, the processor 510 can take a snapshot of the existing image displayed on the first display area and store it in the memory 540. In another embodiment, when a change in the state of the electronic device 501 is detected, the processor 510 can display a snapshot image of the existing image displayed on the first display area on the second display area of ​​the display 520. In yet another embodiment, the processor 510 can display the snapshot image on the second display area of ​​the display 520 until a new image is generated.

[0102] In one embodiment, the processor 510 may perform image processing (e.g., scaling, rotation, blurring, or a combination thereof) on the snapshot image based on the resolution of the second display area, and then display the image-processed snapshot image on the second display area of ​​the display 520.

[0103] In one embodiment, when a new image is generated, the processor 510 may display the new image on the second display area of ​​the display 520 instead of an existing image. In another embodiment, the processor 510 may perform image processing on the new image and may display the processed new image on the second display area of ​​the display 520 for a predetermined time. Alternatively, the processor 510 may display the processed new image for a predetermined time, and then display a new image without image processing on the second display area of ​​the display 520.

[0104] The illustration shows a snapshot image being displayed only when the state of electronic device 501 changes, until a new image is generated. However, this is merely an example, and this disclosure is not limited to the above example. In embodiments, a snapshot image of an existing image may be displayed even when the display area of ​​display 520 changes, until a new image is generated. In embodiments, changes in the display area of ​​display 520 may include enabled display changes (e.g., Figure 4 The changes can be between the first display 440 and the second display 450, changes in the enabled area across the entire area of ​​the display, changes in resolution, or a combination thereof. In embodiments, changes in the enabled area of ​​the display can include changes in size, changes in the position of the enabled area across the entire area of ​​the display, or a combination thereof.
