6 is a diagram for explaining a terminal operation according to a fourth embodiment of the present invention.

Referring to FIG. 6, the user of the terminal grasps both sides of the display unit with both hands as shown on the screen 231, so that each thumb of both hands touches one side of the display unit. The touch sensor provided in the terminal can generate a touch event according to the thumb touch and transmit the generated touch event to the controller. The controller may control to output predetermined content to the display unit when a touch event occurs. For example, the control unit may control the display unit to output any one of contents stored in the storage unit. The controller may control the touch sensor to activate the flexure sensor before or after the touch event occurs.

Next, as shown in FIG. 233, the terminal user can bend the lower left corner A3 by more than a predetermined angle using the left hand while grasping the right side of the terminal with one hand. Then, the touch sensor provided in the terminal continuously transmits the touch event generated in the right side to the control unit, and the bending sensor can generate bending events according to the bending of the lower left corner (A3) over a certain angle. As the lower right corner A1 of the terminal is bent, the display unit bends the lower left corner A3 of the currently output text page.

On the other hand, upon receiving the touch event and the bending event from the touch sensor and the bending sensor, the control unit loads the function table stored in the storage unit, and based on the bending event generated from the lower left corner A3 and the touch event generated from the right side And controls to output the multi-view image B3, which is a corresponding function.

If another content, for example, an audio file is selected in the multi-view image B3, the control unit may terminate the current content and control to reproduce the selected audio file.

7A to 7C are views for explaining the operation of the terminal according to the fifth embodiment of the present invention.

Referring to FIG. 7A, when a touch event occurs on both side portions A and B of the display unit as shown in FIG. 73A in a state where bending does not occur about an axis as shown in FIG. 7A, And control to output the content stored in the storage unit to the display unit in response to the request. Here, the output of the content can be performed according to a touch event occurring at one side of the display unit. For convenience of description, the description will be made on the performance according to a touch event occurring at both sides. The terminal may control to activate the bending sensor when a touch event occurs, and to activate the bending sensor when the touch sensor is activated.

Next, referring to FIG. 7B, as shown in FIG. 71B, the terminal may be more severely bent than the right side portion around the axis. When an asymmetric bend occurs, the terminal can control to display a portion of other contents as shown in FIG. 73B on the side where the bend is severely generated. More specifically, the terminal receives the bending event from the bending sensor according to the bending. The bending angle information included in the bending event from the right side and the bending angle information included in the bending event from the left side can be compared with each other . Accordingly, the terminal can determine that the right side portion has a larger bending angle than the left side portion, so that the terminal can control the right side portion to display the edge regions of other contents at predetermined intervals.

Referring to FIG. 7C, the terminal can determine the size of a width to display a part of the contents according to the touch event (B) and the bending angle transmitted from the right side as shown in 71c. That is, as shown in 71b of FIG. 7b, the terminal displays a small width of the width as shown in 73b as the angle of bending of the right side becomes smaller. As the angle of bending increases as shown in 71c, The size of the width can be controlled to be large.

And adjust the output of the contents according to the touch events A and B as shown in 75c and 77c. The touch event B generated on the right side of the touch event B may move in the right edge direction according to the user's control. Accordingly, the touch event B may be displayed on a predetermined width, Is moved in the right edge direction. At this time, in some areas of the plurality of contents, the content passed through the touch event (B) may be displayed so as to move from right to left in a page turning mode.

7A, when a book having a face sheet corresponding to a plurality of text pages is displayed on a certain text page, that is, a specific face page, And the right side can be gripped using fingers, respectively. Then, when the user wishes to turn the page, the right side of the book, i.e., the opened side, can be gripped using the right hand so that the user can select the pages. At this time, the user can place the thumb of the right hand on the right front side of the book and the remaining four fingers on the right side of the book to grip the side of the book. When the user applies a downward force, the right side of the book is bent so that the face sheets arranged on the side of the book are twisted at a certain angle. At this time, the thumb holds a specific face of the book, that is, the edge corresponding to the text page, and as the warp becomes larger, the warp width of the book face becomes larger as shown in FIGS. 73B and 73C. Meanwhile, as shown in FIG. 7C, when the user pushes the thumb pressing the cotton swabs to the right swivel, the cotton swabs that are not supported by the thumb sweep from right to left due to the elasticity of the swivel. The terminal of the present invention can control to move a text page such that a plurality of text pages corresponding to the above-mentioned face paper are moved in a page turn manner as in the above description. To this end, the terminal continuously senses a touch event and controls some of the text pages to be displayed within a predetermined width according to the warping angle. Then, while the touch of the user moves to the right edge, the text pages whose touch event is canceled move from the left side to the right side to control the next text page to be outputted. In practice, the text page in which the state of the touch event is maintained at the right edge is maintained in a state output to the display unit. When the touch event is released in accordance with the movement of the touch event, the touch event is maintained Is replaced by another text page with

In the above description, the page flipping function of the text pages is implemented as the touch event moves within the warping area of the text pages. However, when the touch event is fixed, the page flipping function is implemented according to the change of the bending event It can be. That is, as described above, the width of the warp region is determined according to the warp angle of the warp event. However, as the warp angle increases, the width of the warp region increases and the touch event B is maintained If the width is greater than the point, some of the text pages may go beyond the touch event (B) point. Accordingly, the terminal can implement a page turn function based on the text pages in which the touch event (B) is canceled, and replace the text page with another text page in which the current touch event (B) is held.

8A and 8B are views for explaining the operation of the terminal according to the sixth embodiment of the present invention.

Referring to FIGS. 8A and 8B, the terminal of the present invention can activate a touch sensor and control the content to be displayed on a display unit, for example, a text page stored in a storage unit according to a user's request. When the text page is displayed on the display unit, the terminal can control to activate the flexion sensor according to the set conditions.

In this state, the terminal can detect that a touch event occurs in the left side portion A and the right lower portion B, respectively. Then, the terminal can detect that a bending event occurs in the lower right (B). The terminal can control to display other contents in which the touch event and the bending event are generated in the lower right part B, that is, the edge areas of the other text pages, overlapping each other at certain positions. Then, the display unit of the terminal can display a state in which the right edge area and the lower edge area of the text page are overlapped and displayed by a predetermined portion as shown in the figure.

In the above-described display state, if the touch event occurring in the lower right B moves in the corner direction of the terminal and the occurrence of the touch event of the text pages changes, the terminal can control to perform the page turn function accordingly . At this time, if the touch event is moved in the right direction or the down direction instead of in the corner direction, the page turning function can be performed in the same manner even if the occurrence of the touch event of the text pages is changed.

9 is a view for explaining operation of a terminal according to a seventh embodiment of the present invention. Prior to the description, it is assumed that the terminal of the present invention activates the touch sensor and outputs a content such as a text page stored in the storage unit to the display unit according to a user's request. If the text page is displayed on the display unit, it is assumed that the terminal controls to activate the flexion sensor according to the set condition.

Referring to FIG. 9, the control unit of the terminal can receive a bending event according to the bending of the right side portion at a predetermined angle from the bending sensor by the physical force applied by the user on the right side. The control unit of the terminal can determine that the bending event generated in the right side of the axis is asymmetric when a bending event occurs as in 91. [ Accordingly, the display unit of the terminal can control to display some areas of other text pages on the right side as in 93. [ At this time, when the specific text page is bookmarked, the control unit of the terminal can control to display the bookmark in the predetermined area. More specifically, when an asymmetric bending event occurs, the controller of the terminal can check the contents stored in the storage unit, that is, the file information of the text pages, and confirm whether the user previously set the bookmark. When the specific text page is set as the book mark, the control unit of the terminal displays some areas of the text pages according to the occurrence of the asymmetric bending event, and displays the text page set as the book mark so as to be distinguishable from other text pages. For example, the terminal control unit may control the output area of the text page set to be bookmarked to be larger than the output area of another text page, or to display the bookmark mark (M) on one side of the output area of the text page have.

On the other hand, if there is a text page set as a bookmark, the terminal control unit can control the page turning function of the book mark setting text page to be distinguished from other text pages, For example, if a touch event of text pages is canceled due to a change of a touch event within a certain width of a certain area of a plurality of text pages, the terminal control unit displays an image corresponding to the text page whose touch event is released And controls the display unit to output another text page in which the touch event is maintained while moving in the left direction. In this process, the terminal control unit may control the movement of the corresponding image having a predetermined time interval based on the point of time when the touch event of the text pages is released. At this time, the terminal control unit can set a longer time than the output time interval of other text pages in the case of a text page set as a book mark. Therefore, when the user performs the page turn function, the text pages can be moved from left to right at predetermined time intervals. The text page set as the book mark can be outputted to the display unit for a longer time than other text pages.

On the other hand, the user can re-designate as a touch event among the text pages moved in accordance with the page turn function, so that the state that the page does not go over and the state output to the display unit is maintained can be controlled. Accordingly, when a text page set as a bookmark is displayed, the user can select the page more easily because the user can output the text page for a relatively long time compared to other text pages. Meanwhile, in the page turning function, the text page is changed at regular time intervals according to the change of the touch event. Even if the touch event is released, the terminal control unit displays the text page on the display unit, that is, , It is possible to perform the movement stop by designating again as the touch event. When a drag or flick occurs during a touch event, the terminal control unit controls the designated text page to be displayed again on the entire display unit, or removes the text page from the display unit.

In the above description, the page turning function has been described in which the image corresponding to the text page is moved at predetermined time intervals after the touch event is released from the touch event of the corresponding text page. However, It can be controlled so that it is immediately moved without a separate time delay at the time of release.

10A to 10D are views for explaining the operation of the terminal according to the eighth embodiment of the present invention.

Referring to FIG. 10A, when a touch event occurs in both sides A and B of the display unit as in 103a in a state where no bending occurs around the axis as in 101a, So that the content stored in the storage unit can be output to the display unit. Here, the output of the content can be performed according to a touch event occurring at one side of the display unit. For convenience of description, the description will be made on the performance according to a touch event occurring at both sides. The terminal may control to activate the bending sensor when a touch event occurs, and to activate the bending sensor when the touch sensor is activated.

Next, referring to FIG. 10B, the terminal may be bent more sharply than the right side portion around the axis as in 101b. If an asymmetric bend occurs, the terminal can control to display a partial area of other contents as shown in 103b on the side where the bend is severely generated. That is, the terminal receives the bending event from the bending sensor according to the bending. The bending angle information included in the bending event from the right side and the bending angle information included in the bending event from the left side can be compared with each other. Accordingly, the terminal can determine that the right side portion has a larger bending angle than the left side portion, so that the terminal can control the right side portion to display the edge regions of other contents at predetermined intervals. Here, when the touch event A is held for a predetermined time or longer, the terminal control unit may generate a page lock bar for setting the current screen state to be maintained as shown in the left part of 103b. It is preferable that the lock bar is formed so that a part of the area where the touch event A is generated overlaps with the area where the touch event A occurs so that the lock bar function can be easily activated or deactivated. The lock bar can be removed from the display unit when the touch event (A) is released.

10C, when the user moves the touch event A to activate the lock bar function, the terminal control unit displays an image corresponding to the activation of the lock bar function on one side of the lock bar or one side of the text page Can be controlled.

Referring to FIG. 10D, the terminal control unit can control to display certain areas of different text pages on the right side according to the lock bar function, even if a separate bending event does not occur as in 101d. In order to distinguish text pages set as book marks in a state where another lock bar function is activated, the terminal control unit displays marks (B1, B2, B3) indicating text pages set as book marks in the predetermined areas as in 103d, Can be controlled. Then, the terminal control unit can control to output the text page by touching any one of the markers.

On the other hand, the form of the flexible display unit according to the embodiment of the present invention may have the form of a display unit in which the center is folded as shown in Fig. 11, the first display unit and the second display unit are connected to each other with respect to the central axis, and the first display unit has a structure that allows the second display unit to be held by the right hand and the second display unit can hold the display unit with the right hand . At this time, if the user bends the second display unit by more than a predetermined angle by using the right hand, the control unit of the terminal can control to perform the page turning function described above based on the bending event transmitted from the bending sensor. At this time, the terminal control unit may control to remove the text page being output to the second display unit by moving to the first display unit.

12A and 12B are views for explaining the operation of a terminal having a flexible display unit according to a ninth embodiment of the present invention.

12A and 12B, the terminal of the present invention has a plurality of peaks generated by bending. Accordingly, the bending sensor provided in the terminal may generate the first and second bending events having different directions and transmit the first and second bending events to the terminal controller. That is, the first bending event includes information indicating that the left or right side is bent upward in the center of the display unit, and the second bending event includes information indicating that the right side or the left side is bent downward about the center of the display unit . ≪ / RTI > When the terminal controller receives a plurality of bending events having different direction values from the bending sensor, the terminal control unit can control to enlarge or reduce the contents arranged in the area where each bending event occurs.

12A, when the region located on the left side of the terminal is bent upward in the center of the display unit and the region located on the right side of the terminal is bent in the downward direction, And transmits the generated first bending event and the second bending event to the control unit. On the other hand, each of the touch sensors can transmit position information about a point touched by a user's finger to the control unit. The terminal can enlarge and display the content arranged in the left region of the terminal on the basis of the touch event and the bending event received from the touch sensor and the bending sensor. In particular, the terminal can control to enlarge and output the content by applying a zoom-in function around a point where a touch event occurs among the contents arranged in the left area. In addition, the terminal can reduce and display the content arranged in the right area of the terminal based on the touch event and the bending event received from the touch sensor and the flexure sensor. In particular, the terminal can control to zoom out and output the content by applying a zoom-out function around a point where a touch event occurs in the content arranged in the right area.

12B, when a region located on the left side of the terminal is bent downward about the center of the display unit and an area located on the right side of the terminal is bent upward, Another first bending event and a second bending event may be generated and transmitted to the control unit. On the other hand, each of the touch sensors can transmit position information about a point touched by a user's finger to the control unit. The terminal can reduce and display the content arranged in the left region of the terminal based on the touch event and the bending event received from the touch sensor and the flexural sensor. In particular, the terminal can control to zoom out and output the content by applying a zoom-out function around the point where the touch event occurs among the contents arranged in the left area. The terminal can enlarge and display the content arranged in the right area of the terminal based on the touch event and the bending event received from the touch sensor and the flexural sensor. In particular, the terminal can control to zoom in on the point where the touch event occurs among the contents arranged in the right area, and output the enlarged contents.

In the above description, two bending events having different left and right contrast directions about the center of the display unit are described, but the present invention is not limited thereto. That is, when the display unit is divided into three and the right and left sides are bent in the same direction and the center minute is bent in a different direction from the left and right sides, the bending sensor generates three bending events, respectively, and can transmit them to the terminal controller. When the terminal control unit receives three bending events from the bending sensor, the terminal control unit may adjust to display the content displayed in the bent area in the downward direction and to display the content displayed in the bent area in the upward direction in an enlarged manner.

The operation of the user function of the terminal based on the touch event and the bending event generated from the touch sensor and the bending sensor provided in the terminal having the flexible display unit according to the embodiment of the present invention has been described above. Hereinafter, a data display method of a terminal having a flexible display unit of the present invention will be described in detail with reference to the drawings.

13 is a flowchart illustrating a data display method of a terminal having a flexible display unit according to an embodiment of the present invention.

Referring to FIG. 13, in step S101, the terminal control unit performs a booting process when power is supplied from a power source unit, controls to output a predetermined standby screen upon completion of booting, and activates a touch sensor And prepare to receive an input signal.

Thereafter, the terminal control unit checks whether or not a touch event has occurred in step S103. If the touch event has not occurred, the terminal control unit may control to maintain the touch sensor activated state by branching to step S101.

Meanwhile, if the touch event occurs in step S103, the terminal control unit may perform the function according to the touch event, and may control to activate the bending sensor by branching to step S105. The terminal performing the bending sensor activation process in step S105 may control to activate the bending sensor substantially in step S101 of activating the touch sensor.

Next, the terminal control unit checks whether or not bending, i.e., bending, occurs in step S107. If the bending does not occur, the terminal control unit branches to step S105 to maintain the state of activating the bending sensor, Performance can be controlled. On the other hand, if warping occurs from one side of the terminal in step S107, the terminal control unit generates a warping event and transfers the warping event to the control unit, and also branches to step S109 and loads the function table stored in the storage unit. The function table is a table describing commands for performing functions according to touch events and warping events.

Accordingly, the terminal control unit can control the performance of the touch event and the warping event based on the function table in step S111. More specifically, the terminal control unit checks whether or not the bending event is a corner bending. If the bending event corresponds to bending the corner, the terminal control unit performs functions such as a folding function, a menu function, And multi-view functions. The folding function may be a function of controlling the folding image to be applied to the content being output to the display unit and outputting the folding image, and to add a content attribute, for example, a book mark attribute. The menu function is a function to output a menu image to the display unit and to activate the touch sensor of the area in which the menu image is output so that items output in the menu image can be executed and the items can be selected. The slide view function outputs other slides of the content currently being outputted on a side of the display unit at a predetermined size and initializes the touch sensor of the corresponding area so that the user can select the slide image. The multi-view function is a function to output images corresponding to other contents stored in the storage unit on one side of the display unit, and to initialize the touch sensor so that the user can activate images in the output region.

In addition, the terminal control unit may determine whether an asymmetric bending event occurs at the center of the display unit, and perform a page turning function when an asymmetric bending event occurs. This page turning function is a function for supporting a user to view a plurality of text pages, and is a function for outputting some areas of other text images in a predetermined width on one side of the display part according to the bending angle of a bending event. At this time, the predetermined width may be increased or decreased in accordance with the bending angle. In some areas of the text page having a predetermined interval within the predetermined width, the predetermined interval may be adjusted according to the size of the predetermined width. That is, when the predetermined width is increased, the predetermined interval is increased, and when the predetermined width is decreased, the predetermined interval may be reduced. When the user generates a touch event within the predetermined width, the terminal control unit removes the text page in which the touch event has been canceled by moving the text page in a predetermined direction and outputs a text page in which the touch event is held to the display unit to be. At this time, if the touch event occurs in certain areas of a plurality of text pages and is released, the terminal control unit may control to move and remove text pages in a predetermined direction at predetermined time intervals. In the case of a text page set by the user as a book mark, the terminal control unit may control to give a certain image so as to be distinguishable from other text pages, or to make a ratio occupied within the predetermined width larger than other text pages When the touch event occurs and then released, it can be controlled to be removed while moving in a certain direction after the speech for a longer time than other text pages. In addition, the terminal control unit provides a lock bar function, so that when the user sets a lock bar function for a specific text page, the predetermined width can be maintained even if a warping event does not continuously occur. At this time, the terminal control unit controls the book mark display to be within a predetermined width so that the bookmarked pages can be easily searched within a predetermined width, and when the bookmark is touched, the terminal control unit controls to move to the corresponding text page .

Wherein the terminal control unit checks whether a plurality of bending events having different directions occur when a bending event occurs, and when the bending events occur, the terminal control unit enlarges or reduces content in the bending region upward or downward And the content in the other area bent in the downward direction or the upward direction can be controlled to be reduced or enlarged.

As described above, the data display method of the terminal having the flexible display unit according to the embodiment of the present invention controls the display of different contents according to the bending area and the bend angle of the terminal, So that the user can view the contents more dynamically and easily.

While the present invention has been described with reference to several preferred embodiments, these embodiments are illustrative and not restrictive. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit of the invention and the scope of the appended claims.
