Description

Electronic device including a flexible display and method for controlling the same

[0001] The present disclosure relates to an electronic device including a flexible display and a method of operating the same.

[0002] As demand for mobile communications increases, and on the other hand, as the integration of electronic devices increases, the portability of electronic devices such as mobile communication terminals can be improved, and the convenience of using multimedia functions can be enhanced. For example, when a display with an integrated touchscreen function replaces a traditional mechanical (button-type) keypad, the electronic device can be miniaturized while maintaining the function of an input device. For example, the portability of the electronic device can be improved by removing the mechanical keypad. In another embodiment of the present disclosure, if the display is expanded by the area where the mechanical keypad is removed, the electronic device including the touchscreen function can provide a larger screen than the electronic device including the mechanical keypad, even if it has the same size and weight as the electronic device including the mechanical keypad.

[0003] When surfing the web or using multimedia functions, it may be more convenient to use an electronic device with a larger screen. While larger displays can be mounted on electronic devices to achieve this, considering the portability of the electronic device, there may be limitations in expanding the display size. In one embodiment of the present disclosure, a display using organic light-emitting diodes (OLEDs) can provide a larger screen while ensuring the portability of the electronic device. For example, a display using OLEDs (or an electronic device equipped with such an OLED) can achieve stable operation even when manufactured to be considerably thin, and thus can be mounted on an electronic device in a foldable, bendable, or rollable form.

[0004] The above information may be provided as background information to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above is applicable as prior art related to the present disclosure.

[0005] The present disclosure addresses at least the problems and / or disadvantages described above, and provides at least the advantages described below. Accordingly, the present disclosure provides an electronic device including a flexible display and a method of operating the same.

[0126] Referring to FIG. 6, in operation 610, an electronic device (e.g., the electronic device (101) of FIG. 1, the processor (120) of FIG. 1, the electronic device (101) of FIG. 2, the electronic device (101) of FIG. 3, the electronic device (101) of FIG. 4, the electronic device (101) of FIG. 5A, or the electronic device (101) of FIG. 5B) may display an execution screen of a first application in a first area of ​​a flexible display (e.g., the display module (160) of FIG. 1, the display (203) of FIG. 2, the display (203) of FIG. 3, the display (231) of FIG. 4, the display (231) of FIG. 5A, or the display (231) of FIG. 5B) while the display area is a first size.

[0127] According to one embodiment of the present disclosure, a size of a display area of ​​a flexible display visible to the outside of the electronic device may be variable from a first size to a second size based on movement of at least a portion of a housing (e.g., a first housing (201) of FIG. 2 or a second housing (202) of FIG. 2). For example, the first size may be a smallest size of the display area of ​​the flexible display, and the second size may be a largest size of the display area of ​​the flexible display.

[0128] According to one embodiment of the present disclosure, the top of the display area may include a status bar that displays the status of the electronic device (e.g., carrier information, clock information, battery level, network connection information, notification information, communication status, or notification).

[0129] According to one embodiment of the present disclosure, the bottom of the display area may include a control bar (e.g., a navigation bar) including at least one UI for controlling the electronic device (e.g., a key for checking recently used applications, a home key, or a back key).

[0130] According to one embodiment of the present disclosure, the electronic device may display a first application execution screen in a first area excluding a status bar and / or a control bar among a display area of ​​a first size.

[0131] According to one embodiment of the present disclosure, in operation 620, the electronic device may display at least a portion of an execution screen of a first application or a simplified screen of the execution screen of the first application in a second area including at least a portion of the first area while the display area is changed from a first size to a second size.

[0132] According to one embodiment of the present disclosure, an electronic device may change a display area from a first size to a second size based on receiving a user input for adjusting the size of the display area and executing a multi-window function while the display area is at a first size.

[0133] According to one embodiment of the present disclosure, a user input for adjusting the size of a display area and executing a multi-window function (e.g., double-pressing a physical key for adjusting the size of a display area) may be different from a user input for adjusting the size of a display area (e.g., single-pressing a physical key for adjusting the size of a display area).

[0134] According to one embodiment of the present disclosure, when the electronic device adjusts the size of the display area from a first size to a second size based on receiving a user input for adjusting the size of the display area, the electronic device can display a lower portion of the execution screen of the first application that was not visible in the first size in the display area of ​​the second size.

[0135] According to one embodiment of the present disclosure, an electronic device may perform a multi-window function by increasing the size of a display area and dividing the display area into two areas based on a user input received for adjusting the size of a display area and executing a multi-window function. For example, operations 620 and 630 described below may be performed simultaneously while the size of the display area is changed from a first size to a second size.

[0136] According to one embodiment of the present disclosure, in operation 630, the electronic device may display an execution screen of a second application in a third area including at least a portion of a newly visible display area (e.g., the second display area (A2) of FIG. 3) outside the electronic device while the display area changes from a first size to a second size, corresponding to the size of the display area.

[0137] According to one embodiment of the present disclosure, the third region may be positioned below the second region (e.g., in the -Y-axis direction). For example, when the flexible display moves upward (e.g., in the +Y-axis direction) and the size of the display region increases, or when the flexible display moves downward and the size of the display region decreases, the second region may be positioned above the display region, and the third region may be positioned below the display region.

[0138] According to one embodiment of the present disclosure, when the size of the display area changes based on the movement of the flexible display, the changes in the second area and the third area will be described below with reference to FIG. 7.

[0139] According to one embodiment of the present disclosure, the third region may be positioned to the left of the second region. For example, when the flexible display moves to the right and the size of the display region increases, or when the flexible display moves to the left and the size of the display region decreases, the second region may be positioned to the right of the display region, and the third region may be positioned to the left of the display region.

[0140] According to one embodiment of the present disclosure, the third region may be positioned to the right of the second region. For example, when the flexible display moves to the left and the size of the display region increases, or when the flexible display moves to the right and the size of the display region decreases, the second region may be positioned to the left of the display region, and the third region may be positioned to the right of the display region. Although the present disclosure describes an embodiment in which the flexible display moves upward (in the +Y direction), the present disclosure may also be applied when the flexible display moves to the left or right.

[0141] According to one embodiment of the present disclosure, as illustrated in FIG. 7, while the display area changes from a first size to a second size, the electronic device may reduce the size of a second area related to an execution screen of a first application, and increase the size of a third area related to an execution screen of a second application, which includes at least a portion of the display area newly shown to the outside. According to one embodiment of the present disclosure, the electronic device may reduce the size of the second area on which the execution screen of the first application is displayed, while the size of the third area on which the execution screen of the second application is displayed increases. According to one embodiment of the present disclosure, while the size of the display area increases based on the movement of the flexible display, the electronic device may reduce the proportion of the second area within the display area, and increase the proportion of the third area, which is the remaining area.

[0142] According to one embodiment of the present disclosure, the speed at which the execution screen of the second application is displayed in response to the size of the display area may be different from the speed at which the size of the flexible display display area changes. According to one embodiment of the present disclosure, the speed may include both speed and direction. According to one embodiment of the present disclosure, at least one of the speed or direction at which the execution screen of the second application moves within the display area may be different from at least one of the speed or direction at which the size of the display area changes.

[0143] In this way, since the speed at which the execution screen of the second application is displayed is different from the speed at which the execution screen of the first application is displayed, different animation effects can be provided to the execution screen of the first application and the execution screen of the second application.

[0144] FIG. 7 is a drawing for explaining an area of ​​a multi-window based on a change in a display area of ​​a flexible display of an electronic device according to an embodiment of the present disclosure.

[0145] Referring to FIG. 7, an electronic device (e.g., an electronic device (101) of FIG. 1, a processor (120) of FIG. 1, an electronic device (101) of FIG. 2, an electronic device (101) of FIG. 3, an electronic device (101) of FIG. 4, an electronic device (101) of FIG. 5A, or an electronic device (101) of FIG. 5B) may display an execution screen (e.g., A of FIG. 7) of a first application in a first area (710) of a display area of ​​a flexible display (e.g., a display module (160) of FIG. 1, a display (203) of FIG. 2, a display (203) of FIG. 3, a display (231) of FIG. 4, a display (231) of FIG. 5A, or a display (231) of FIG. 5B)) that is visible from the outside, when the display area is a first size. For example, the first area (710) may be the same as the display area, or may be an area excluding the status bar at the top and / or the control bar at the bottom of the display area.

[0146] According to one embodiment of the present disclosure, when a user input for adjusting the size of the display area (e.g., increasing) and executing a multi-window function is received while the size of the display area is a first size, the electronic device can move the flexible display in an upward direction (e.g., in the +Y-axis direction).

[0147] According to one embodiment of the present disclosure, the electronic device may reduce the size of a second area (711) including at least a portion of a first area (710) and associated with an execution screen of a first application (e.g., A of FIG. 7) as the flexible display moves upward. According to one embodiment of the present disclosure, the reduction in the size of the second area (711) may mean that the vertical length (e.g., Y-axis direction) of the second area (711) is reduced. According to one embodiment of the present disclosure, based on the reduction in the size of the second area (711), at least a portion of the execution screen of the first application or a simplified version of the execution screen of the first application may be displayed in the second area (711). According to one embodiment of the present disclosure, the simplified screen may include a screen in which an image included in the execution screen of the first application is changed based on the second area or a screen in which a preview screen is changed based on the second area.

[0148] For example, when the flexible display moves upward by a first length (720), the bottom of the second area (711) where the execution screen of the first application is displayed can be reduced by the first length (720).

[0149] According to one embodiment of the present disclosure, as the flexible display moves upward, the electronic device may display a newly displayed display area at the bottom of the electronic device. According to one embodiment of the present disclosure, the electronic device may display an execution screen of a second application (e.g., B of FIG. 7) in a third area (740) that includes at least a portion of the newly displayed display area. According to one embodiment of the present disclosure, the size of the third area (740) may increase as the flexible display moves upward. According to one embodiment of the present disclosure, an increase in the size of the third area (740) may mean an increase in the vertical length of the third area (740).

[0150] For example, if the flexible display is moved upward by a first length (720), the vertical length (730) of the third area (740) where the execution screen of the second application (e.g., B of FIG. 7) is displayed may be the first length (720) plus the vertical length of the newly displayed display area.

[0151] According to one embodiment of the present disclosure, based on the completion of the movement of the flexible display, the reduction of the second region (711) and the increase of the third region (740) may also be completed. For example, when the flexible display moves upward by a second length (721) and the movement is completed, the vertical length of the second region (712) in which the reduction is completed may be the same as the second length (721), and the vertical length (731) of the third region (741) in which the increase is completed may be the same as the vertical length (71) of the display region before the movement. According to one embodiment of the present disclosure, the ratio of the horizontal length and the vertical length of the second region (712) in which the reduction is completed (e.g., 16:9) may be the reciprocal of the ratio of the horizontal length and the vertical length of the third region (741) in which the increase is completed (e.g., 9:16).

[0152] According to one embodiment of the present disclosure, the electronic device may increase the size of the third region (740) based on moving the upper end of the third region upward from the lower end of the display region in accordance with the movement of the flexible display. According to one embodiment of the present disclosure, as illustrated in FIG. 8, the speed at which the execution screen of the second application displayed in the third region is displayed may be faster than the speed at which the flexible display is moved.

[0153] FIG. 8 is a diagram illustrating a change speed of a display area of ​​a flexible display of an electronic device according to an embodiment of the present disclosure and a movement speed of each area of ​​a multi-window. For example, FIG. 8 illustrates a movement speed when a flexible display, a first application execution screen, and a second application execution screen all move in the same direction (e.g., upward (+Y direction)).

[0154] Referring to FIG. 8, the movement speed (810) of the flexible display (e.g., the display module (160) of FIG. 1, the display (203) of FIG. 2, the display (203) of FIG. 3, the display (231) of FIG. 4, the display (231) of FIG. 5A, or the display (231) of FIG. 5B) may gradually increase from 0 when the movement begins, maintain a constant speed, and then decrease the speed before the movement is completed, so that the speed becomes 0 when the movement is completed (e.g., in a slide-out state). According to one embodiment of the present disclosure, the movement distance of the flexible display may be the area between the graph (y-axis or speed v-axis) representing the movement speed (810) and the x-axis (or time t-axis).

[0155] According to one embodiment of the present disclosure, the movement speed (820) of the execution screen of the first application displayed before the movement of the flexible display may be the same as the movement speed (810) of the flexible display (or, the speed at which the size of the display area of ​​the flexible display changes). For example, when the movement speed (820) of the execution screen of the first application and the movement speed (810) of the flexible display are the same, it may be the case that the uppermost part of the execution screen of the first application moves along with the movement of the flexible display and is also displayed in a second area including at least a part of the first area.

[0156] According to one embodiment of the present disclosure, when a part of the execution screen of the first application except for the top area is displayed in the second area, the movement speed (821) of the execution screen of the first application may be faster than the movement speed (810) of the flexible display. According to one embodiment of the present disclosure, the movement distance of the part of the execution screen of the first application except for the top area (the distance displayed by movement on the flexible display) may be greater than the movement distance of the flexible display because the top area of ​​the execution screen of the first application must be displayed by movement by more than the movement distance of the flexible display.

[0157] According to one embodiment of the present disclosure, the movement speed (830) of the execution screen of the second application newly displayed from the bottom of the display area according to the movement of the flexible display may be faster than the movement speed (810) of the flexible display.

[0158] According to one embodiment of the present disclosure, the movement speed (830) of the upper part of the execution screen of the second application may be faster than the movement speed (810) of the flexible display because, while the flexible display is moving, it must move a distance longer than the movement distance of the flexible display from the bottom of the display area.

[0159] According to one embodiment of the present disclosure, the movement speed (820, 821, 830) of the execution screen of the application and the movement speed (810) of the flexible display may be the perceived speed at which the content displayed on the flexible display moves in the user's line of sight.

[0160] According to one embodiment of the present disclosure, the movement distance at the top of the execution screen of the second application may be the area between the graph indicating the movement speed (830) and the x-axis.

[0161] According to one embodiment of the present disclosure, referring to FIG. 8, it can be confirmed that both the movement of the execution screen of the first application and the movement of the execution screen of the second application are completed based on the completion of the movement of the flexible display.

[0162] Returning to FIG. 6, according to one embodiment of the present disclosure, the direction in which the execution screen of the second application displayed in the third area may be different from the direction in which the flexible display moves. According to one embodiment of the present disclosure, the electronic device may increase the size of the third area based on moving at least a portion of the third area from at least one of the left end or the right end of the third area. An embodiment in which the direction in which the execution screen of the second application is displayed and the direction in which the flexible display moves are different according to one embodiment of the present disclosure will be described below with reference to FIG. 10.

[0163] According to one embodiment of the present disclosure, the electronic device may reduce the size of the second area where the execution screen of the first application is displayed while increasing the size of the third area where the execution screen of the second application is displayed. According to one embodiment of the present disclosure, the electronic device may gradually cause some areas of the execution screen of the first application to disappear while reducing the size of the second area.

[0164] According to one embodiment of the present disclosure, when a user input for adjusting the size of a flexible display and executing a multi-window function is received, the electronic device may determine a portion of an area to be displayed in a second area that has been moved within a displayed execution screen of a first application. For example, the electronic device may determine the uppermost area corresponding to the size of the second area that has been moved within the execution screen of the first application as a portion of an area to be displayed in the second area that has been moved. According to one embodiment of the present disclosure, the electronic device may determine an image or a preview screen included in the execution screen of the first application as a portion of an area to be displayed in the second area that has been moved within the execution screen.

[0165] According to one embodiment of the present disclosure, the electronic device may cause an area other than a portion to be displayed in a second area that has completed moving within the execution screen of the first application to gradually darken or blur and disappear while the flexible display moves.

[0166] According to one embodiment of the present disclosure, an operation of gradually disappearing a portion of the execution screen of the first application while the size of the second area is reduced will be described below with reference to FIG. 9a.

[0167] According to one embodiment of the present disclosure, if the size of an image or preview screen included in the execution screen of the first application is larger than the size of the second area that has been moved, the electronic device can gradually reduce the size of the image or preview screen included in the execution screen of the first application while the flexible display is moved, and change it to the size of the second area that has been moved.

[0168] According to one embodiment of the present disclosure, based on the completion of the reduction in the size of the second region, a portion of the execution screen of the first application, excluding a portion of the second region, or a simplified screen may be displayed. According to one embodiment of the present disclosure, the simplified screen may be a screen in which an image included in the execution screen of the first application is changed based on the second region in which the movement has been completed, or a screen in which a preview screen is changed based on the second region in which the movement has been completed.

[0169] According to one embodiment of the present disclosure, the electronic device may display a portion of the execution screen of the second application overlapping a portion of the execution screen of the first application while the size of the third area where the execution screen of the second application is displayed increases. An embodiment in which a portion of the execution screen of the second application overlaps a portion of the execution screen of the first application while the size of the third area increases based on the movement of the flexible display according to one embodiment of the present disclosure will be described below with reference to FIG. 10.

[0170] According to one embodiment of the present disclosure, the electronic device can display a boundary between the second area and the third area based on the completion of an increase in the size of the third area where the execution screen of the second application is displayed.

[0171] According to one embodiment of the present disclosure, an electronic device may display at least one UI for controlling at least one of an execution screen of a first application or an execution screen of a second application on a portion of a boundary. According to one embodiment of the present disclosure, the at least one UI may include at least one of a UI for switching the positions of the execution screens of the first application and the execution screens of the second application, a UI for changing the second execution screen of the second application to a home screen, or a UI for changing the execution screen of the second application to an execution screen of a recently used application. According to one embodiment of the present disclosure, an operation of displaying a UI for controlling an execution screen on a boundary between the second area and the third area will be described below with reference to FIG. 9C.

[0172] According to one embodiment of the present disclosure, when the size of the third area where the execution screen of the second application is displayed has been increased, the ratio of the horizontal length and vertical length of the second area may be the reciprocal of the ratio of the horizontal length and vertical length of the third area.

[0173] According to one embodiment of the present disclosure, the execution screen of the second application displayed in the third area may be a home screen.

[0174] According to one embodiment of the present disclosure, the execution screen of the second application displayed in the third area may be an application related to the first application displayed in the second area.

[0175] For example, based on whether the execution screen of the first application is the execution screen of the front camera or the execution screen of the rear camera, the electronic device may display a preview screen of the execution screen of the front camera or the execution screen of the rear camera in the second area. According to one embodiment of the present disclosure, the electronic device may display the other one of the execution screen of the front camera or the execution screen of the rear camera as the execution screen of the second application in the third area. According to one embodiment of the present disclosure, when a user input for adjusting the size of the display area and executing a multi-window is received while displaying the execution screen of the front camera or the rear camera in the first area while the display area is at the first size, the operation of the electronic device will be described below with reference to FIGS. 11A and 11B.

[0176] According to one embodiment of the present disclosure, when a notification event occurs (e.g., a message is received) while the execution screen of a first application is displayed in a first area, the electronic device may display a notification message. For example, the notification message may be displayed as a pop-up screen for a set period of time.

[0177] According to one embodiment of the present disclosure, an electronic device may change a display area from a first size to a second size based on receiving a user input for resizing a display area and executing a multi-window while a notification message is displayed.

[0178] According to one embodiment of the present disclosure, an electronic device may display an execution screen of a second application related to a notification message in a third area. According to one embodiment of the present disclosure, the resizing of the display area and the multi-window execution operation while the notification message is displayed will be described below with reference to FIG. 12A.

[0179] According to one embodiment of the present disclosure, the electronic device may move the second area based on receiving a user input while displaying a UI indicating that additional information can be displayed in a portion of the execution screen of the first application.

[0180] According to one embodiment of the present disclosure, an electronic device may display an application list or widget screen related to a first application in a second partition area of ​​a second area. According to one embodiment of the present disclosure, an operation when a user input is received while a UI indicating that additional information can be displayed is displayed will be described below with reference to FIGS. 14 and 15.

[0181] In this way, while the area where the execution screen of the second application is displayed increases, the area where the execution screen of the first application is displayed decreases, and by gradually causing a part of the execution screen of the first application to disappear, different animation effects can be provided to the execution screen of the first application and the execution screen of the second application.
