Description

Display device and control method thereof

[0001] The present disclosure relates to a display device and a method for controlling the same.

[0002] A display device is a device that displays signals input from the outside or signals and data stored internally as video or images through a display panel. Display devices have generally been used in TVs, monitors, and portable electronic devices.

[0003] As technology advances, display devices capable of performing handwriting on display panels have been developed. In particular, electronic whiteboard-type display devices that can replace blackboards used in classrooms or conference rooms have been developed and are in use. These display devices have the advantage of being able to store handwritten content and infinitely expand the area on the display panel where handwriting can be performed.

[0004] In addition, the orientation of the screen can be changed by pivoting the display device using a hinge.

[0005] However, when pivoting the screen direction by 90 degrees in this way, there was a problem in that the content displayed on the display panel before pivoting rotated together with the display panel, making it difficult for the user to continue writing on the board.

[0006] According to at least one embodiment of the present disclosure, a display device and a control method thereof may include, in the display device, a display, a body portion that supports the display in a rotatable state, a memory, and at least one processor.

[0007] The above at least one processor controls the display to display a page containing an object drawn according to a user's handwriting motion on the display, and if the display is rotated relative to the body part, controls the display to change the display direction of the object based on the direction of rotation, and if the handwriting motion is performed on a plurality of consecutive pages, can create a roll file connecting the plurality of pages and store it in the memory.

[0008] For example, the display may be rotatable to one of a first position in which the horizontal length is longer than the vertical length and a second position in which the vertical length is longer than the horizontal length.

[0009] The above at least one processor can control the display to display the vertical length of the page to fit the screen of the display while changing the display direction of the object according to the rotation direction when the display is rotated from the first position to the second position, and to display the horizontal length of the page to fit the screen of the display while changing the display direction of the object according to the rotation direction when the display is rotated from the second position to the first position.

[0010] For example, the at least one processor may generate the roll file to include at least one page displayed in a first direction and at least one page displayed in a second direction perpendicular to the first direction when the display is rotated at least once while the writing operation is performed on the plurality of pages.

[0011] For example, the above at least one processor may add a new page in a direction corresponding to the user operation, following the currently displayed page, when a user operation to specify a specific direction relative to the display is input while the display is in the first position or the second position.

[0012] For example, when a user operation to specify a specific direction is input in a page area among the plurality of pages while an intermediate area between the plurality of pages is displayed on the display, the above-mentioned at least one processor may add a new page that is displayed in the same direction as the one page in a direction corresponding to the user operation for the one page.

[0013] For example, when a user operation to specify a specific direction is input while an intermediate area between the plurality of pages is displayed on the display, the above-mentioned at least one processor may add a new page that is displayed in the same direction as the page that is displaying the widest area among the plurality of pages, in a direction corresponding to the user operation.

[0014] For example, when a user operation to specify a specific direction is input while at least one of the pages displayed in the first direction and at least one page displayed in the second direction is displayed, the above-mentioned at least one processor may add a new page displayed in the same direction as the currently displayed page in a direction corresponding to the user operation.

[0015] For example, the at least one processor can control the display to display the entire layout in the direction in which the plurality of pages are connected when a view mode is executed while an intermediate area between the plurality of pages is displayed on the display.

[0016] For example, when a view mode is executed while one page in which new pages are added in at least two different directions among the plurality of pages is displayed on the display, the at least one processor can control the display to divide and display the entire layout of the displayed page and each of the new pages among the plurality of pages according to the connected directions.

[0017] For example, when a user operation to separate the roll file into at least two files is input to the at least one processor, the plurality of pages within the roll file can be separated into at least two files based on the connection direction and stored in the memory.

[0018] A control method for a display device according to one embodiment of the present disclosure may include: displaying a page containing an object drawn according to a user's handwriting motion on the display; changing the display direction of the object based on the direction of rotation when the display is rotated; and, when the handwriting motion is performed on a plurality of consecutive pages, creating and saving a roll file that connects the plurality of pages together.

[0019] For example, the display may be rotatable to one of a first position in which the horizontal length is longer than the vertical length and a second position in which the vertical length is longer than the horizontal length.

[0020] The step of changing the display direction of the object may be such that when the display is rotated from the first position to the second position, the display direction of the object is changed according to the rotation direction, and the vertical length of the page is displayed to fit the screen of the display, and when the display is rotated from the second position to the first position, the display direction of the object is changed according to the rotation direction, and the horizontal length of the page is displayed to fit the screen of the display.

[0021] For example, the step of creating and saving the roll file may include at least one page displayed in a first direction and at least one page displayed in a second direction perpendicular to the first direction when the display is rotated at least once while the writing operation is performed on the plurality of pages.

[0022] For example, when the display is in the first or second position, if a user operation to specify a specific direction relative to the display is input, the method may further include the step of adding a new page in a direction corresponding to the user operation following the currently displayed page.

[0023] For example, when an intermediate area between the plurality of pages is displayed on the display and a user operation to specify a specific direction is input in the area of ​​one of the plurality of pages, the method may further include the step of adding a new page that is displayed in the same direction as the one page, corresponding to the direction of the user operation for the one page.

[0024] For example, when a user operation to specify a specific direction is input while an intermediate area between the plurality of pages is displayed on the display, the method may further include the step of adding a new page that is displayed in the same direction as the page with the widest area among the plurality of pages, in a direction corresponding to the user operation, with respect to the page with the widest area among the plurality of pages.

[0025] For example, when a user operation to specify a specific direction is input while at least one of the first page displayed in the first direction and at least one page displayed in the second direction is displayed, the method may further include the step of adding a new page displayed in the same direction as the currently displayed page in a direction corresponding to the user operation.

[0026] For example, when a view mode is executed while an intermediate area between the plurality of pages is displayed on the display, the method may further include a step of displaying the entire layout in the direction in which the plurality of pages are connected.

[0027] For example, when a view mode is executed while one page in which new pages are added in at least two different directions among the plurality of pages is displayed on the display, the method may further include a step of dividing and displaying the entire layout of the displayed page and each of the new pages among the plurality of pages according to the connected directions.

[0028] For example, when a user operation to separate the roll file into at least two files is input, the method may further include the step of separating and saving the plurality of pages within the roll file into at least two files based on the connection direction.

[0054]

[0055] Hereinafter, a display device and a control method thereof according to various embodiments will be described in detail with reference to the attached drawings.

[0056] FIG. 1 is a perspective view of a display device and a control method thereof according to one embodiment of the present disclosure.

[0057] Referring to FIG. 1, the display device (1) may include a display (11) and a body part (12).

[0058] The body part (12) supports the display (11) in a rotatable state. The body part (12) and the display (11) are connected through a hinge part (121) and can be rotated clockwise or counterclockwise with respect to the hinge part (121).

[0059] In FIG. 1, the body part (12) is shown in the form of a stand that stands on the floor, but this is merely an example, and if the display device (1) is a wall-mounted type that is attached to a wall, the body part (12) may be implemented in the form of a structure for fixing to the wall.

[0060] The body part (12) may include some components necessary for the operation of the display device (1). For example, memory and a processor may be included in the body part (12). However, it is not limited thereto, and such components may be provided in the display (11).

[0061] The display device (1) is a device for displaying a signal input from an external device or a signal stored in the display device (1) as an image. The display device (1) can be implemented as an electronic whiteboard.

[0062] An electronic whiteboard is a device capable of writing on a display (11) according to touch input by an input means such as a user's hand or a separately provided pen-type device. An electronic whiteboard is not necessarily a device intended for writing, and can be applied to various devices for the purpose of detecting touch and outputting images. In the present disclosure, writing or writing action may be an action in which a user writes or draws various objects, such as pictures, characters, or symbols, on the display (11), and writing content may be content displayed by such action, i.e., objects.

[0063] However, the display device (1) does not necessarily have to be implemented as an electronic whiteboard, and various embodiments of the present disclosure can be applied as long as the device is equipped with a display and the horizontal and vertical directions can be changed by rotation, etc.

[0064] For example, it can be implemented not only as stand-type or wall-mounted devices such as TVs, monitors, and kiosks, but also as portable devices such as smartphones, tablet PCs, PDAs, laptop computers, media players, game players, and navigation systems.

[0065] Alternatively, the display device (1) may be a type of wearable terminal.

[0066] For convenience of explanation, the following description is based on the case where the display device (1) is implemented as an electronic whiteboard.

[0067] The display (11) is configured to display various screens. The display (11) can detect a user's touch by using a touch sensor provided internally. Accordingly, the user's handwriting content can be displayed as is. The display (11) may include at least one of an LCD, LED, LPD, OLED, AMOLED, FLED, and micro-OLED.

[0068]

[0069] * The display (11) may include a display panel on which an image is displayed, a housing that forms the exterior of the display device (1) and protects the internal components of the device from the external environment, and a housing for fixing the display panel. The housing may cover the rear and side surfaces of the substrate side of the display panel. The housing may be implemented in a bezel-less form. Although the present disclosure describes examples in which both the housing and the display panel have the same shape, the shapes of the housing and the display panel do not necessarily have to be the same. For example, if the display device (1) is mounted inside another electronic device such as a refrigerator, the housing may be formed to have a shape for being embedded in the refrigerator regardless of the shape of the display panel.

[0070] The body part (12) is configured to support the display (11). The display (11) can be rotatably coupled to the body part (12). In other words, the display (11) can be rotated through a hinge part (121) connected to the body part (12). In this case, if the hinge part (121) includes a driving motor, the rotation operation can be performed automatically, but it is not necessarily limited to this. For example, a user may rotate the display (11) by their own strength.

[0071] In the case of a conventional electronic whiteboard, when the display (11) rotates, the content being written also rotates along with the display (11). As shown in FIG. 1, when the display (11) is in the shape of a rectangle where the horizontal length is greater than the vertical length, the state on the left side of FIG. 1 can be described as the horizontal direction, and the state on the right side as the vertical direction. While writing on the display (11) placed in the horizontal direction as in FIG. 1, if the display (11) rotates in the vertical direction, the written content also becomes vertical. Therefore, it may be difficult for the user to continue writing.

[0072] A display device (1) according to at least one embodiment of the present disclosure changes the display direction of the written content, i.e., the object, according to the direction of rotation when the display (11) rotates relative to the body part (12). That is, when the display (11) is rotated 90 degrees clockwise so that the display (11) is positioned vertically, the display device (1) controls the display (11) to rotate the display direction of the object 90 degrees counterclockwise. Accordingly, despite the rotation of the display (11), the written content, i.e. the object, can be seen horizontally in alignment with the original writing direction.

[0073] Meanwhile, when used in the form of an electronic whiteboard, there are cases where the user must continue writing even after writing on the entire screen of the display (11). In the case of a conventional whiteboard, the content already written must inevitably be erased, but in the case of an electronic whiteboard, the user can continue writing on a new page by turning to the previous page without erasing the currently displayed writing content. In this case, multiple pages can be created consecutively. When writing operations are performed consecutively on multiple pages in this way, the display device (1) can connect these pages to create a single file. This file may be referred to by various terms such as book, integrated page, or roll, but below it will be described as a roll file. That is, a roll file can be a single data bundle containing multiple pages.

[0074] Additionally, a page serves as a criterion for distinguishing data included within a roll file. Pages can be divided into units of the entire screen that the display (11) displays at once, or into units of each print page that is printed when the roll file is printed on paper or as an image file. In the case of division into units of the entire screen, content written on multiple pages may be printed together on a single print page.

[0075] As described above, according to various embodiments of the present disclosure, in a structure in which the display (11) is freely rotatable, the user can perform writing while rotating the display (11) in various directions, such as horizontal or vertical, according to convenience, thereby enabling the creation of roll files in various forms. Accordingly, the display direction of the pages included in the roll file can also be a form in which horizontal and vertical directions are mixed.

[0076] FIG. 2 is a drawing for explaining a body portion of a display device according to one embodiment of the present disclosure.

[0077] Referring to FIG. 2, the body part (12) can rotate the display (11) when an event to rotate the display (11) occurs. Here, examples of events to rotate the display (11) include when a user command to rotate the display (11) is input or when a user terminal device communicating with the display (11) is rotated, but are not necessarily limited thereto. For example, rotation can also occur when the aspect ratio of the content to be displayed on the display (11) is identified as being suitable for a vertical display. Meanwhile, if the hinge part (121) connecting the body part (12) and the display (11) does not include a motor, the user may manually rotate the display (11).

[0078] The display (11) is connected to the body part (12) through a hinge part (121).

[0079] The body part (12) can rotate the display (11) into a first posture (landscape posture or horizontal posture) or a second posture (portrait posture or vertical posture). Here, the first posture is a posture in which the horizontal length of the display (11) is longer than the vertical length, and the second posture is a posture in which the vertical length of the display (11) is longer than the horizontal length. Alternatively, the first posture may be referred to as horizontal direction and the second posture as vertical direction.

[0080] For example, when a user command to rotate the display (11) is entered while the display (11) is in a first position, the body part (12) can rotate the display (11) 90 degrees clockwise or counterclockwise.

[0081] In this case, the display (11) can be in a second position. That is, the body part (12) can rotate the display (11) in increments of approximately 90 degrees and maintain the rotated state.

[0082] Conversely, when a user command to rotate the display (11) is input while the display (11) is in a second position, the body part (12) can rotate the display (11) counterclockwise.

[0083] However, the direction and angle in which the body part (12) rotates the display (11) are not necessarily limited to this.

[0084] In order to automatically rotate the display (11), the hinge portion (121) may include a driving member. The driving member is configured to provide a driving force to rotate the display (11) mounted on the body portion (121). The driving member may include a motor that generates rotational force.

[0085] The driving member may include a motor (1211), a motor driver (1212), a sensor (1213), and a switch (1214).

[0086] The motor (1211) is positioned to rotate the gear (1215) connected to the display (11), and the display (11) can be rotated by rotating the gear (1215) according to the control of the processor through the motor driver (1212).

[0087] The motor (1211) can be a stepper motor, for example, and can be implemented as an AC motor, a DC motor, etc.

[0088] The sensor (1213) can detect the rotation of the display (11). Specifically, the sensor (1213) can detect the rotation of the display (11) connected to the gear (1215) by detecting the rotation of the gear (1215) which is rotated by the motor (1211).

[0089] For example, the sensor (1213) may be implemented as an encoder, but the sensor (1213) of the body part (12) according to the present disclosure is not necessarily limited thereto.

[0090] The switch (1214) may be a configuration related to controlling at least one of the rotation angle or rotation speed of the display (11). The switch (1214) may be implemented as a limit switch, but is not necessarily limited thereto.

[0091] Meanwhile, the above description regarding the configuration of the body part (12) is merely for the purpose of explaining one embodiment, and the body part (12) according to the present disclosure is not necessarily limited to the configuration according to the above description. That is, the body part (12) can be applied without limitation as long as it is configured to support the display (11) in a rotatable state.

[0092] FIG. 3 is a block diagram for explaining the configuration of a display device according to one embodiment of the present disclosure.

[0093] Referring to FIG. 3, the display device (1) may include a display (11), a processor (1000), and a memory (2000).

[0094] The processor (1000) is configured to control the overall operation of the display device (1). The processor (1000) may be composed of one or more processors.

[0095] One or more processors (1000) may include at least one of a CPU (Central Processing Unit), a GPU (Graphic Processing Unit), and an NPU (Neural Processing Unit), but are not limited to the examples of the processors (1000) described above.

[0096] The CPU is a general-purpose processor capable of performing not only general operations but also artificial intelligence operations, and it can efficiently execute complex programs through a multi-layered cache structure. The CPU is advantageous for serial processing methods, which enable the organic linkage between previous and next calculation results through sequential computation. General-purpose processors are not limited to the examples mentioned above, except for cases specified as the aforementioned CPU.

[0097] A GPU is a processor designed for massive computations, such as floating-point operations used in graphics processing, and can perform large-scale computations in parallel by integrating a large number of cores. In particular, GPUs may be advantageous over CPUs for parallel processing methods, such as convolution operations. Additionally, GPUs can be used as co-processors to complement the functions of CPUs. Processors for massive computation are not limited to the examples mentioned above, except for cases specified as GPUs.

[0098] An NPU is a processor specialized for artificial intelligence computations using artificial neural networks, and each layer constituting the neural network can be implemented in hardware (e.g., silicon). In this case, since the NPU is designed to be specialized according to the specifications required by the vendor, it has a lower degree of flexibility compared to CPUs or GPUs, but it can efficiently process the AI ​​computations required by the vendor. Meanwhile, as a processor specialized for AI computations, the NPU can be implemented in various forms such as TPUs (Tensor Processing Units), IPUs (Intelligence Processing Units), and VPUs (Vision Processing Units). Artificial intelligence processors are not limited to the examples mentioned above, except for cases specified as NPUs.

[0099] The processor (1000) may be implemented as at least one System on Chip (SoC). In this case, the SoC may further include a memory (2000) and a network interface such as a bus for data communication between the processor (1000) and the memory (2000), in addition to one or more processors (1000).

[0100] Memory (2000) is a configuration for storing various data, programs and instructions, etc.

[0101] The processor (1000) can perform various operations by controlling the operation of the display (11) and the driving unit (12) according to instructions stored in the memory (2000). For example, the processor (1000) can control the display (11) to display a page containing an object that is drawn according to the user's handwriting motion on the display (11). Alternatively, when an event occurs that requires the display (11) to be changed to a specific posture, the driving member of the hinge unit (121) can be controlled so that the display (11) takes on either a first posture or a second posture.

[0102] The processor (1000) can control the display (11) to change the display direction of an object based on the direction of rotation when the display (11) is rotated relative to the body part (12). For example, if the display (11) is rotated clockwise, the display (11) can be controlled to rotate the object in the opposite direction, counterclockwise. In this way, even if the display (11) is rotated during writing, the user can view the writing content in the same direction as the original writing direction and continue writing.

[0103] When a writing operation is performed on multiple consecutive pages, the processor (1000) can create a single roll file by connecting multiple pages together and store it in memory (2000).

[0104] Below, the process of changing the display direction of an object displayed according to the rotation of the roll file stored in memory (2000) and the display (11) is described in detail.

[0105] FIG. 4 is a drawing for explaining the screen configuration of a display device according to one embodiment of the present disclosure.

[0106] Referring to FIG. 4, a drawn object can be displayed on the display (11) according to the user's handwriting motion. The object can be displayed immediately at the exact location where the user is writing. The area where the object according to the user's handwriting motion can be displayed in this way can be called a page (P).

[0107] Pages (P) may be singular or multiple. When the user performs the initial handwriting operation on the display (11), there may be a single page (P). Subsequently, when pages (P) are added by specific actions of the user, multiple pages (P1, P2, ..., Pn) may be displayed in a connected format. That is, multiple pages (P1, P2, ..., Pn) may be interconnected and displayed in a form such as a 'roll,' which can be referred to as a roll file.

[0108] An area where multiple different pages (P1, P2, ..., Pn) are connected to each other can be called an intermediate area (C). An object (e.g., a solid line or a dotted line) may be displayed in the intermediate area to allow the user to intuitively recognize that it is an area between pages.

[0109] Based on user settings or default values ​​of the display device (1), the switching speed between multiple pages may vary. For example, if a transition to the second page is required while the first page is being displayed, the first page may be designed to transition directly to the second page. Alternatively, the transition to the second page may be designed to be smooth while gradually displaying the intermediate area between the first page and the second page. Or, if the design allows for writing in the intermediate area between pages, the next page in that direction may be gradually displayed as the writing continues to one side, while the previous page is pushed to the opposite side.

[0110] FIG. 4 illustrates a state in which a user adds a page to the right while writing on a horizontal display (11). As the page is added, the first page (P1) is pushed to the left, and a middle area is displayed, showing a part of the second page (P2) on the right. Afterwards, when a page is added to the right again, the third page (P3) is added and displayed in the same way.

[0111] In this way, multiple pages (P1, P2, ..., Pn) can be scrolled and displayed in various ways within the display (11) by a specific action of the user. That is, the display (11) does not necessarily display only one page (P), and multiple pages (P1, P2, ..., Pn) and multiple intermediate areas (C1, C2, ..., Cn-1) may be displayed together.

[0112] FIGS. 5A and 5B are drawings for explaining various examples of a screen display method when a display according to one embodiment of the present disclosure rotates from a first position to a second position.

[0113] Referring to FIG. 5a, the display (11) may be rotatable from a first position (11-1) having a horizontally long length to a second position (11-2) having a vertically long length.

[0114] Since the display (11) is rotatably mounted on the body part (12), it can be rotated from the first position (11-1) to the second position (11-2) or from the second position (11-2) to the first position (11-1) by means of the hinge part (121).

[0115] Specifically, when the display (11) is in the first position (11-1), the horizontal length (L1) may be longer than the vertical length (L2).

[0116] When the display (11) is in the second position (11-2), the vertical length (L3) may be longer than the horizontal length (L4).

[0117] The second position (11-2) may be a state in which the display (11) is rotated approximately 90 degrees in one direction relative to the hinge portion (121) from the first position (11-1).

[0118] When the display (11) is rotated from a first position (11-1) to a second position (11-2), the processor (1000) can change the display direction of the object according to the rotation direction and display the vertical length (H1) of the page (P) to fit the screen of the display (11).

[0119] Specifically, the vertical length (H1) of the page (P) can be displayed to match the vertical length (L3) of the second position display (11-2).

[0120] As the vertical length (H1) of the page (P) is adjusted, the size of the object displayed on the page (P) can be enlarged.

[0121] In addition, the display direction of the object can be rotated together with the rotation of the display (11) to be displayed.

[0122] For example, when the number of objects displayed on the display (11) is 5 in the first position (11-1), when the display (11) is rotated to the second position (11-2), the number of objects displayed on the display (11) may be 2 as the vertical length (H1) of the page (P) is adjusted.

[0123] In this case, objects that are not displayed on the display (11) may be displayed on the display (11) as the page (P) is scrolled in one direction according to the user's operation (e.g., sweep action) or as the size of the page (P) is reduced according to the user's other operation (e.g., shrink command action).

[0124] FIG. 5b illustrates an example different from FIG. 5a. According to FIG. 5b, when changing from the first position (11-1) to the second position (11-2), the entire content that was displayed is displayed on the upper page (P1) of the display (11) of the second position (11-1) while maintaining the aspect ratio of the original page (P), and the next second page (P2) is displayed below it. Depending on the size of the page, the next third page (P3) may be displayed at the bottom. Pages that the user has not yet written on (e.g., the second page or the third page) may be displayed as virtual pages. For example, they may be displayed in a different color compared to the first page (P1), displayed somewhat transparently, or displayed with text or images added to indicate that they are virtual pages. If the writing is finished and saved without writing on these virtual pages, the second and third pages may not be included in the roll file.

[0125] FIG. 6 is a drawing for explaining that a display according to one embodiment of the present disclosure is rotated from a second position to a first position.

[0126] Referring to FIG. 6, the display (11) can be rotated from a second position (11-2) with a vertically long length to a first position (11-1) with a horizontally long length.

[0127] When the display (11) is rotated from the second position (11-2) to the first position (11-1), the processor (1000) can change the display direction of the object according to the direction of rotation and display the horizontal length (H2) of the page (P) to fit the screen of the display (11).

[0128] Specifically, the horizontal length (L2) of the page (P) can be displayed to match the horizontal length (L1) of the first position display (11-1).

[0129] As the width (H2) of the page (P) is adjusted, the size of the object displayed on the page (P) can be enlarged.

[0130] In addition, the display direction of the object can be rotated together with the rotation of the display (11) to be displayed.

[0131] For example, when the second position (11-2) is used, if the number of objects displayed on the display (11) is 5, when the display (11) is rotated to the first position (11-1), the number of objects displayed on the display (11) may be 2 as the horizontal length (H2) of the page (P) is adjusted.

[0132] As described above, the size of the page (P) displayed on the display (11) is enlarged or reduced in correspondence with the rotation of the display (11), so that the objects included in the page (P) can also be rotated and enlarged to be displayed together.

[0133] The example of Fig. 6 may also be modified differently, just like Fig. 5b. For example, after changing from the second position to the first position, the original page's aspect ratio may be maintained and displayed on the far left of the first position's display (11), and at least one virtual page may be additionally displayed to the right of it.

[0134] FIG. 7 is a drawing for explaining that a page is added when a display according to one embodiment of the present disclosure is in a first position.

[0135] Referring to FIG. 7, when the display (11) is in a first position (11-1), if a user operation to specify a specific direction relative to the display (11) is input, a new page corresponding to the user operation may be added following the currently displayed page (P). The user operation to specify a specific direction can be input in various ways. For example, it may be implemented by touching any point on the screen and dragging or quickly swiping in one direction, touching a specific menu displayed on the screen (e.g., an arrow or other direction-specifying menu), touching a point adjacent to the top, bottom, left, or right edges of the screen, or by the user speaking a user voice to specify the direction.

[0136] For example, when the display (11) is in the first position (11-1) and a user operation to sweep to the left relative to the display (11) is input, a new page (P2) can be added to the right of the currently displayed page (P1).

[0137] The newly added page (P2) can be connected to the existing page (P1) through an intermediate area (C1) to be created as a single roll file.

[0138] Since the page (P) is added while the display (11) is maintained in the first position (11-1), the newly added page (P2) may have the same shape as the existing page (P1).

[0139] For example, when the display (11) is in the first position (11-1) and a user operation of sweeping upward relative to the display (11) is input, a new page (P4) may be added below the currently displayed page (P3).

[0140] The newly added page (P4) can be created as a roll file by connecting it to the existing page (P3) and the intermediate area (C2).

[0141] FIG. 8 is a drawing for explaining that a page is added when a display according to one embodiment of the present disclosure is in a second position.

[0142] Referring to FIG. 8, when the display (11) is in a second position (11-2), if a user operation to specify a specific direction relative to the display (11) is input, a new page may be added in the direction corresponding to the user operation following the currently displayed page (P). As described above, user operations can be implemented in various ways, but the following description is based on the case where a sweep operation is performed.

[0143] For example, when the display (11) is in a second position (11-2), if a user operation to sweep downward relative to the display (11) is input, a new page (P6) may be added below the currently displayed page (P5).

[0144] The newly added page (P6) can be created as a roll file by connecting it to the existing page (P5) and the intermediate area (C3).

[0145]

[0146] *For example, when the display (11) is in a second position (11-2) and a user operation to sweep to the left relative to the display (11) is input, a new page (P8) can be added to the right of the currently displayed page (P7).

[0147] The newly added page (P8) can be created as a roll file by connecting it to the existing page (P7) and the intermediate area (C4).

[0148] FIG. 9 is a drawing for explaining how a new page is added when a display according to one embodiment of the present disclosure is in a different position.

[0149] Referring to FIG. 9, when the display (11) is rotated at least once while a user's handwriting operation is performed on a plurality of pages (P), a roll file may be generated including at least one page (P-1) displayed in a first direction and at least one page (P-2) displayed in a second direction perpendicular to the first direction.

[0150] For example, when a first-position display (11-1) in which a first-position page (P-1) is displayed is rotated to a second position (11-2) and a user operation to sweep to the left is input, a new second-position page (P-2) can be added to the right of the first-position page (P-1).

[0151] Afterwards, when the display (11) is rotated to the first position (11-1) and a user operation to sweep to the left is input, a new page (P-3) in the first direction can be added to the right of the page (P-2) in the second direction.

[0152] At this time, the entire area of ​​the new page (P-3) can be displayed on the display (11) in correspondence with the current position of the display (11) (e.g., second position (11-2)). That is, only the newly added page (P-3) can be displayed on the display (11).

[0153] Multiple pages (P-1, P-2, P-3) in different directions can be generated as roll files, each connected to an intermediate area (C).

[0154] Meanwhile, user operations to add a new page (P) are not necessarily limited to a left swipe motion.

[0155] For example, when a first-position display (11-1) in which a first-position page (P-1) is displayed is rotated to a second position (11-2) and a user operation of a downward sweep motion is input, a new second-position page (P-2) can be added below the first-position page (P-1).

[0156] FIG. 10 is a drawing for explaining the configuration of a roll file including a plurality of pages according to one embodiment of the present disclosure.

[0157] Referring to FIG. 10, when a user operation to specify a specific direction is input while at least one page (P-1) displayed in a first direction and at least one page (P-2) displayed in a second direction is displayed, a new page (P) displayed in the same direction as the currently displayed page (P) can be added in a direction corresponding to the user operation.

[0158] Accordingly, in a single roll file, a page (P-1) displayed in a first direction and a page (P-2) displayed in a second direction can be connected and displayed in various directions.

[0159] For example, the second page (P2) may be a page (P) added by inputting a user operation of a left sweep motion when the display (11) showing the first page (P1) is in the first position (11-1).

[0160] The third page (P2-1) may be a page (P) added by inputting a user operation of a downward sweep motion when the display (11) showing the second page (P2) is in the first position (11-1).

[0161] The fourth page (P2-2) may be a page (P) added by inputting a user operation of an upward sweep motion when the display (11) showing the second page (P2) is in the first position (11-1).

[0162] The fifth page (P3) may be a page (P) added by inputting a user operation of a left sweep motion when the display (11) showing the second page (P2) is in the second position (11-2).

[0163] As such, when the display (11) is in the first position (11-1) or the second position (11-2), the shape and direction of the new page (P) added to the existing page (P) may vary depending on the type and / or direction of user operation input to add the new page (P).

[0164] In this case, the generated roll file may include multiple pages (P) connected in various directions.

[0165] FIGS. 11 and FIGS. 12 are drawings for explaining that a new page is added when a plurality of pages are displayed on a display according to one embodiment of the present disclosure.

[0166] Referring to FIG. 11, when an intermediate area (C) between multiple pages (P) is displayed on the display (11) and a user operation to specify a specific direction is input to one of the pages (P), a new page (P) can be added to one page (P) in the same direction as one page (P) in a direction corresponding to the user operation.

[0167] In the first position display (11-1), the first direction page (P-1) and the second direction page (P-2) can be displayed together with the intermediate area (C).

[0168] At this time, if a user operation to sweep to the left is input to an area of ​​the display (11) where the first direction page (P-1) is displayed, a new first direction page (P-1a) can be added to the right of the first direction page (P-1).

[0169] As described above, user operation for specifying a specific direction is not necessarily limited to a sweep motion. User operation for specifying a specific direction may be a touch motion of a specific part of the display (11). For example, it may be a touch motion of an area adjacent to one side of the display (11) where the first direction page (P-1) is displayed.

[0170] Meanwhile, if a user operation to specify a specific direction is input into an area of ​​the display (11) where the second direction page (P-2) is displayed, a new page with the same shape as the second direction page (P-2) may be added to the left, top, or bottom of the second direction page (P-2).

[0171] Referring to FIG. 12, when an intermediate area (C) between multiple pages (P) is displayed on the display (11), if a user operation to specify a specific direction is input, a new page (P) can be added to the page (P) that has the largest area among the multiple pages (P) in the same direction as the page (P) that has the largest area in the direction corresponding to the user operation.

[0172] For example, in the second position display (11-2), a second direction page (P-2) and a first direction page (P-1) may be displayed together with an intermediate area (C). The area of ​​the second direction page (P-2) displayed on the display (11) may be larger than that of the first direction page (P-1).

[0173] At this time, when a user operation of touching any area of ​​the display (11) and then swiping upward is input, the processor (1000) can identify that the upward direction is stored. The processor can add a new page (P-2a) corresponding to the large area page (P-2) among the pages being displayed, following the first direction page (P-1).

[0174] Here, user operation to specify a specific direction is not necessarily limited to an upward sweep motion. User operation to specify a specific direction may be a touch motion on a specific part of the display (11). For example, it may be a touch motion on an area close to one side of the display (11).

[0175] Meanwhile, if the first direction page (P-1) displayed on the display (11) has a larger area than the second direction page (P-2), the newly added page may have the same shape as the first direction page (P-1).

[0176] In addition, the number of pages (P) displayed on the display (11) is not necessarily limited to two. For example, even if three or more pages (P) are displayed in any direction on the display (11), when a specific user action is input, a new page (P) with the same shape as the page (P) displayed with the largest area among the multiple pages (P) displayed may be added in a direction corresponding to the user action.

[0177] FIGS. 13 and FIGS. 14 are drawings for explaining when a view mode is executed in a display device according to one embodiment of the present disclosure.

[0178] The view mode may be an image for providing overall information about multiple pages (P) included in the roll file. In the view mode, multiple pages (P) included in the roll file may be displayed in a reduced size. Objects written by the user may be displayed on the reduced multiple pages (P) displayed in the view mode.

[0179] When a specific operation is input for one of the multiple pages (P) displayed in view mode by the user, the corresponding page (P) can be displayed on the display (11) as a full screen.

[0180] Referring to FIG. 13, when a view mode is executed while an intermediate area (C) between multiple pages (P) is displayed on the display (11), the entire layout (V) in the direction in which multiple pages (P) are connected can be displayed.

[0181] For example, when multiple pages (P1, P2) are connected horizontally with respect to the display (11) by an intermediate area (C), when a view mode is executed while the intermediate area (C) is displayed on the display (11), the entire layout (V) for horizontal pages (P1, P2, P3, P4) including multiple pages (P1, P2) can be displayed.

[0182] The overall layout (V) for the horizontal pages (P1, P2, P3, P4) can be displayed at the bottom of the display (11).

[0183] However, the area where the entire layout (V) is displayed is not limited to the bottom of the display (11). For example, when the view mode is executed, the entire layout (V) may be displayed in any one of the top, left, right, or bottom areas of the display (11).

[0184] Referring to FIG. 14, when a view mode is executed while one page (P) is displayed on the display (11) with at least two new pages (P) added in different directions among the plurality of pages (P), the entire layout of the displayed page (P) and each new page (P) among the plurality of pages (P) can be divided and displayed according to the connected directions.

[0185] For example, the first page (P1) and the second page (P2) are connected to the left of the display (11), the fifth page (P5) is connected to the top, the sixth page (P6) is connected to the bottom, and the third page (P3) is connected to the right of the fourth page (P4) and can be displayed on the display (11).

[0186] In other words, the third page (P3) may be a page (P) in which new pages (e.g., the fourth page (P4), the fifth page (P5), and the sixth page (P6)) are added in at least two different directions.

[0187] Only the third page (P3) may be displayed on the display (11).

[0188] In this state, when the view mode is executed, the entire layout (V1) for multiple horizontal pages (e.g., P1, P2, P3, P4) sequentially connected including the third page (P3) can be displayed at the bottom of the display (11).

[0189] Additionally, the entire layout (V2) for a plurality of sequentially connected vertical pages (e.g., P5, P3, P6), including the third page (P3), can be displayed on one side of the display (11).

[0190] In this way, other pages (P) connected to the page (e.g., P3) currently displayed on the display (11) are divided according to the direction of connection and displayed on the display (11) as separate layouts (e.g., V1, V2), so that the user can efficiently understand information about the page (P3) currently displayed and the pages (P) connected to it.

[0191] Meanwhile, the area where each layout (V1, V2) is displayed is not necessarily limited to what is shown in the drawing, and may be determined as a specific area by the manufacturer during the manufacturing process of the display device (1). Alternatively, the area where the layout (V1, V2) is displayed may be set to any area of ​​the display (11) by the user inputting a separate action.

[0192] FIGS. 15 and 16 are drawings for explaining the process of saving a roll file according to one embodiment of the present disclosure.

[0193] A roll file can be stored in memory (2000) as a single file. A single roll file may contain multiple pages connected in at least two different directions (see FIG. 12 and FIG. 13).

[0194] Referring to FIG. 15, when a user operation to separate a roll file into at least two files is input, multiple pages (P) within the roll file can be separated into at least two files based on the connection direction and stored in memory (2000).

[0195] For example, a roll file may include three pages (P1, P2, P4) connected horizontally around one page (P3) and two pages (P5, P6) connected vertically (see FIG. 12 and FIG. 13).

[0196] At this time, when a user's file separation operation is input, a roll file for multiple pages (P1, P2, P3, P4) connected in the horizontal direction, a roll file for multiple pages (P5, P3, P6) connected in the vertical direction, and a roll file including all of the multiple pages may be generated.

[0197] A file separation operation may be a user command to separate and save files. When the user touches any point on the screen or selects a specific button provided on the display device (1), the processor (1000) may display a pop-up window containing at least one menu. The user may select a desired menu from the pop-up window. If the file separation and saving menu is selected, the processor (1000) may separate and save the files according to the display direction of each page. User operations for file separation may be implemented in various other ways.

[0198] Referring to FIG. 16, the user operation for file separation may be a long-press operation on the display (11).

[0199] When a roll file is created, the processor (1000) assigns a temporary name to the roll file and then controls the display (11) to display a screen (1601) containing the roll file with the temporary name. In this state, if the user long-presses the screen, the processor (1000) controls the display (11) to display a pop-up window (1602) asking whether to separate the entire roll file.

[0200] When the user selects a menu to execute separation by the user in the pop-up window (1602), the processor (1000) separates the files into multiple files, assigns a new temporary name to each file, and displays it on the screen (1603). However, if a command to not execute separation by the user is entered, only the entire roll file may be stored in memory (2000).

[0201] User operations for separating the entire roll file are not necessarily limited to the above operations. For example, the entire roll file may be separated when a double-tap operation by the user is input. User operations for separating the entire roll file in this manner can be predetermined by the manufacturer of the display device (1). Alternatively, the entire roll file may be separated and saved in response to a specific operation by the user.

[0202] As the roll files are stored separately according to the direction of combination in this way, each separated roll file can be printed individually.

[0203] FIG. 17 is a drawing for explaining a print selection image displayed on a display according to one embodiment of the present disclosure.

[0204] Referring to FIG. 17, when a user inputs a print operation for a roll file, multiple pages (P) can be divided according to the direction in which they are combined and displayed in a print popup window in a preview format.

[0205] The images (1701, 1702, 1703) displayed here in a preview format may be the same or similar to the images displayed in the layout of FIG. 14 (e.g., V1, V2).

[0206] In this way, multiple pages (P) are divided into multiple roll files and a preview is displayed according to the direction in which they are combined, allowing the user to efficiently check information about the multiple connected pages (P) to be printed.

[0207] FIG. 18 is a flowchart illustrating a control method for a display device according to one embodiment of the present disclosure.

[0208] Referring to FIG. 18, a control method for a display device according to one embodiment of the present disclosure can display a page including an object that is drawn according to a user's handwriting operation on the display (S1810).

[0209] Writing actions can be performed by the user's body (e.g., fingers) or through a separate device (e.g., a stylus pen). To this end, the display may be configured as a touch screen. The display may detect the position of the user's fingers or a separate device through pressure, electrical signals, or optical sensors. The display may be a resistive touch screen, a capacitive touch screen, or an infrared touch screen, but the type of display is not necessarily limited to the touch screens listed above.

[0210] The display can be formed to have a rectangular shape with different widths and heights.

[0211] The display can be rotatably coupled to a body portion that supports the display. The body portion may include a hinge portion and a driving member for rotating the display.

[0212] As the driving member operates, the display can be rotated to a specific position.

[0213] For example, the display can be rotated into one of a first position where the horizontal length is longer than the vertical length, or a second position where the vertical length is longer than the horizontal length.

[0214] In other words, when the display is in the first position, the display may have the shape of a horizontally elongated rectangle. When the display is in the second position, the display may have the shape of a vertically elongated rectangle.

[0215] Here, horizontal and vertical directions are defined based on the ground: the direction parallel to the ground is called horizontal, and the direction perpendicular to the ground is called vertical.

[0216] When the display is rotated, the display direction of the object can be changed based on the direction of rotation (S1820).

[0217] When the display is rotated from the first position to the second position, the display direction of the drawn object may change according to the user's handwriting movements when the display was in the first position. The object may be rotated and displayed in response to the rotation of the display. For example, when the display is rotated from the first position to the second position by a certain angle, the object may be rotated by the same angle in a direction opposite to the direction of rotation of the display. Accordingly, the object may be displayed on the display in the second position in the same direction as when the display was in the first position. For example, if the character 'A' is drawn on the display in the first position, the character 'A' may still be displayed on the display even if the display is rotated to the second position.

[0218] Conversely, when the display is rotated from the second position to the first position, the display direction of the object drawn according to the user's handwriting motion when the display was in the second position can be changed in correspondence with the rotation of the display.

[0219] For example, if the character 'A' is drawn on the display in the second position, the character 'A' can still be displayed on the display even if the display is rotated to the first position.

[0220] Meanwhile, when the display is rotated from a first position to a second position, the vertical length of the page displayed on the display can be adjusted to correspond to the vertical length of the rotated display.

[0221] In the first position, the vertical length of the display may be shorter than the vertical length of the display in the second position. Therefore, when the display is rotated from the first position to the second position, the vertical length of the page displayed on the display may increase. Accordingly, the size of the object displayed on the page may be enlarged to the extent that the vertical length of the page increases.

[0222] Meanwhile, when the display is rotated from the second position to the first position, the horizontal length of the page displayed on the display can be adjusted to correspond to the horizontal length of the rotated display.

[0223] In the second position, the horizontal length of the display may be shorter than the horizontal length of the display in the first position. Therefore, when the display is rotated from the second position to the first position, the horizontal length of the page displayed on the display may increase. Accordingly, the size of the object displayed on the page may be enlarged to the extent that the horizontal length of the page increases.

[0224] However, the vertical or horizontal length of the page is not necessarily adjusted to lengthen in response to changes in the display orientation.

[0225] For example, if the orientation of the display changes, the entire area of ​​the page that was displayed on the display before the change can also be displayed as the entire area on the display with the changed orientation.

[0226] Specifically, when the display is rotated from a first position to a second position, the horizontal length of the page displayed on the display in the first position can be shortened to correspond to the horizontal length of the display in the second position.

[0227] Conversely, when the display is rotated from the second position to the first position, the vertical length of the page displayed on the display in the second position can be shortened to correspond to the vertical length of the display in the first position.

[0228] In such cases, objects displayed on the page after the display is rotated may be displayed in a reduced size compared to objects displayed on the page before the display is rotated.

[0229] When a writing operation is performed on multiple consecutive pages, a single roll file can be created and saved by connecting the multiple pages together (S1830).

[0230] While a writing operation is performed on multiple pages, if the display is rotated at least once, a roll file can be generated including at least one page displayed in a first direction and at least one page displayed in a second direction perpendicular to the first direction.

[0231] For example, when the display is in a first or second position, if a user operation to specify a specific direction relative to the display is input, a new page can be added in the direction corresponding to the user operation following the currently displayed page.

[0232] Specifically, when a user operation of a leftward sweep motion is input while the display is in the first position, a new page can be added to the right of the page currently displayed on the display, having a rectangular shape with a long horizontal length, that is, a shape corresponding to the shape of the display in the current first position.

[0233] Alternatively, if a user operation of a leftward sweep motion is input while the display is in the second position, a new page can be added to the right of the page currently displayed on the display, having a rectangular shape with a long vertical length, that is, a shape corresponding to the shape of the display in the current second position.

[0234] Meanwhile, since user operation is not necessarily limited to a left sweep motion, a new page having a shape corresponding to the current display orientation can be added to the bottom, top, and left of the currently displayed page, respectively, according to an up sweep motion, a down sweep motion, and a right sweep motion.

[0235] Meanwhile, when an intermediate area between multiple pages is displayed on the display, if a user operation to specify a specific direction is input in the area of ​​one of the multiple pages, a new page can be added to the page that is displayed in the same direction as the page corresponding to the user operation.

[0236] For example, when two pages connected by an intermediate area are displayed on a display, if user operation is input in a direction other than the direction of the intermediate area for one of the two pages, a new page with the same shape as one of the pages can be added in the opposite direction.

[0237] Here, user operation may be a sweep motion in a specific direction, but is not necessarily limited thereto, and may also be a touch motion on a specific part of a page area. In addition to this, actions for user operation can be defined in various ways in several embodiments.

[0238] Meanwhile, when a user operation to specify a specific direction is input while an intermediate area between multiple pages is displayed on the display, a new page can be added to the page with the widest area among the multiple pages in the same direction as the page with the widest area, in the direction corresponding to the user operation.

[0239] For example, when two pages connected by an intermediate area are displayed with different areas, if a user operation of a sweep motion in a specific direction is input from any area within the display, a new page with the same shape as the page with the widest area displayed in the direction opposite to the specific direction can be added.

[0240] Meanwhile, when a user operation to specify a specific direction is input while at least one of the first page displayed in the first direction and at least one page displayed in the second direction is displayed, a new page displayed in the same direction as the currently displayed page can be added in the direction corresponding to the user operation.

[0241] For example, if the display is in a first or second position and the page where one page is displayed on the display is in the first direction, when a user operation to specify a particular direction is input, a new page in the first direction can be added in the direction corresponding to the user operation.

[0242] Alternatively, if the page displayed on the display is in the second direction, when user operation is input, a new page in the second direction can be added in the direction corresponding to the user operation.

[0243] Meanwhile, if View Mode is executed while the intermediate area between multiple pages is displayed on the screen, the entire layout in the direction where the multiple pages are connected can be displayed. The description of View Mode will be omitted to the extent that it overlaps with the aforementioned content.

[0244] For example, when a view mode is executed when multiple pages are connected horizontally relative to the display and the intermediate area is displayed on the display, the entire layout of all horizontally connected pages, including the multiple pages currently displayed on the display, can be displayed in one area of ​​the display.

[0245] Meanwhile, when a view mode is executed while a single page is displayed with at least two new pages added in different directions among multiple pages, the entire layout of the displayed page and each new page among the multiple pages can be divided and displayed according to the connected directions.

[0246] For example, when only one page is displayed on the display and one other page is connected to the top, bottom, left, and right of the displayed page, when the view mode is executed, the entire layout of multiple pages connected horizontally, including the currently displayed page, can be displayed in one area of ​​the display.

[0247] At the same time, the entire layout of multiple pages connected vertically, including the page currently displayed on the display, can be displayed in other areas of the display.

[0248] Here, one area of ​​the display and the other area may be perpendicular to each other. That is, the horizontal layout may be displayed horizontally at the bottom of the display, and the vertical layout may be displayed vertically at the right side of the display.

[0249] However, since the display area where the layout is displayed is not limited to this, the format of the layout can be implemented in various ways in several embodiments.

[0250] Meanwhile, if a user operation to separate a roll file into at least two files is input, multiple pages within the roll file can be separated into at least two files based on the connection direction and saved.

[0251] For example, a roll file may contain multiple pages connected horizontally and multiple pages connected vertically to one of the pages.

[0252] When a user operation for file separation is input, multiple pages connected horizontally and multiple pages connected vertically can be separated and saved as different files.

[0253] In addition, when print mode is executed, previews of the pages included in the entire roll file, as well as previews of multiple pages connected horizontally and multiple pages connected vertically, can be displayed separately.

[0254] According to the various embodiments described above, the user can easily write on the display device while rotating it in various directions, and can also save the written content as a single roll file. Accordingly, the usability of the display device can be significantly increased.
