20140054438
This application claims the benefit under 35 U.S.C. §119(a) of a Korean patent application filed on Aug. 23, 2012 in the Korean Intellectual Property Office and assigned Serial No. 10-2012-0092623, the entire disclosure of which is hereby incorporated by reference.

In general, flexible display apparatuses refer to image display apparatuses that are implemented by generating a flexible substrate using plastics or a polymer film. Such a flexible display apparatus may be implemented as a Liquid Crystal Display (LCD), an Organic Light Emitting Diode (OLED), electronic ink e-paper, or the like. Because such a flexible display is made by substituting a related-art glass substrate with elastic material, the flexible display can be bent or rolled like paper and is easy to carry.
However, the flexible display apparatus according to the related art is merely bent by a human force. As a result, if the force applied to the flexible display apparatus is not maintained, the flexible display apparatus returns to the original shape thereof due to the elasticity of the flexible display. Therefore, the user is inconvenienced by the return of the flexible display apparatus to the original shape thereof when the user places the flexible display apparatus in a desired shape and wants the flexible display apparatus to hold the shape.

According to various embodiments of the present disclosure, the flexible apparatus 100 of
The flexible apparatus 100 may be made of flexible material such that the flexible apparatus 100 can be bent by external force and thereby have the shape thereof changed. The flexible apparatus 100 may detect a bending according to various methods. Hereinafter, a method for detecting bending of the flexible apparatus 100 will be explained with reference to
Referring to
In order to detect the bending of the flexible apparatus 100, the sensor 110 may include a bend sensor which is disposed on one surface such as a front surface or a rear surface of the flexible apparatus 100, or a bend sensor which is disposed on opposite surfaces of the flexible apparatus 100.
The bend sensor recited herein refers to a sensor that can be bent and that has a resistance value which varies according to a degree of bending. The bending sensor may be implemented in various forms such as an optical fiber bending sensor, a pressure sensor, a strain gauge, and/or the like.
Referring to
As illustrated in
Referring to
In addition, according to various embodiments of the present disclosure, the shape, number, and location of bend sensors may be variously changed. For example, the flexible apparatus 100 may include a single bend sensor or a plurality of bend sensors which are connected to one another. The single bend sensor may detect one bending data, but may include a plurality of detecting channels to detect a plurality of bending data.
Although line type bend sensors are used in the above-described various embodiments of the present disclosure, the sensor 110 may detect bending using a plurality of strain gages.
Referring to
Hereinafter, a method in which the sensor 110 detects bending of the flexible apparatus 100 using the bend sensors which are arranged in a grid pattern, or the strain gages will be explained.
The bend sensors may be implemented by using an electric resistance sensor which uses an electric resistance, or a micro optical fiber sensor which uses a strain of an optical fiber. Hereinafter, the bend sensor will be explained with the assumption that the bend sensor is the electric resistance sensor for the convenience of explanation.
Referring to
For example, the sensor 110 detects the resistance value of the bend sensor using a level of a voltage applied to the bend sensor or a size of an electric current flowing in the bend sensor, and detects bending of the flexible apparatus 100 using the resistance value.
For example, when the flexible apparatus 100 is bent in the horizontal direction as shown in
In this case, the magnitude of the tension increases in proportion to a degree of bending. When the flexible apparatus 100 is bent as shown in
In contrast, the degree of bending gradually decreases toward the outside. Accordingly, the bend sensor 41-1 has smaller resistance values at positions increasingly further away from the point a3 to the left and right. The point a1 and a left area thereof and the point a5 and a right area thereof at which bending does not occur have the same values as before. The same is applied to the other bend sensors 41-2 to 41-5, and corresponding points b1 to b5, c1 to c5, d1 to d5, and e1 to e5.
The controller 130 may determine bending of the flexible apparatus 100 based on a result of detecting by the sensor 110. Specifically, the controller 130 may determine a location of a bending area, a size of the bending area, a number of bending areas, a size of a bending line, a location of the bending line, a number of bending lines, a direction of the bending line, a number of times that bending occurs, and/or the like, based on a relationship between the points at which a change in the resistance value is detected.
The bending area is an area in which the flexible display apparatus is bent. Specifically, because the bend sensor can also be bent by bending the flexible apparatus 100, all points at which the bend sensors output different resistance values from originals values may delineate a bending area. An area at which no change in the resistance value occurs may be delineated as a flat area at which bending does not occur.
When a distance between the points at which the change in the resistance value is detected lies within a predetermined distance, the sensor 110 detects the points as one bending area. On the other hand, when the distance between the points at which the change in the resistance value is detected lies beyond the predetermined distance, the sensor 110 delineates different bending areas with reference to these points.
As described above, in
Accordingly, the controller 130 determines an area 42 which includes all of the points, from the points a1 to a5 of the bend sensor 41-1, from the points b1 to b5 of the bend sensor 41-2, from the points c1 to c5 of the bend sensor 41-3, from the points d1 to d5 of the bend sensor 41-4, and from the points e1 to e5 of the bend sensor 31-5, as one bending area.
The bending area may include a bending line. The bending line refers a line which connects the points at which the greatest resistance value is detected in each bending area. Accordingly, the controller 130 may determine a line which connects the points at which the greatest resistance value is detected in the bending area as a bending line.
For instance, in the case of
In contrast, according to various embodiments of the present disclosure, the sensor 110 may detect bending of the flexible apparatus 100 using a strain gage.
Specifically, when the flexible apparatus 100 is bent, a force is exerted to a strain gage which is arranged along an edge of the flexible apparatus 100 and a different resistance value is output from the strain gage according to a magnitude of the applied force. Accordingly, the controller 130 may determine a location of a bending area, a size of the bending area, a number of bending areas, a size of a bending line, a location of the bending line, a number of bending lines, a direction of the bending line, a number of times that bending occurs, and/or the like, based on the output value of the strain gage.
For example, as illustrated in
The controller 130 may determine a line that connects points at which the strain gages output the resistance values greatly different from those of the original state in the bending area as a bending line. For example, the controller 130 may determine, as a bending line, a line that connects at least two strain gages to which the greatest force is applied, or at least two strain gages to which the next greatest force is applied according to bending of the flexible apparatus 100.
For example, when the flexible apparatus 100 is bent in the horizontal direction as shown in
In the above-described embodiment, the strain gages 51-1, 51-2, . . . are embedded in the front surface of the flexible apparatus 100. The strain gages 51-1, 51-2, . . . may be embedded in the front surface of the flexible apparatus 100 to detect bending of the flexible apparatus 100 in a Z+ direction.
The bending direction of the flexible apparatus 100 refers to a direction in which the bent flexible apparatus 100 curves. For example, on the assumption that the front surface of the flexible apparatus 100 is a 2-dimensional x-y plane, when the bent flexible apparatus 100 curves in a z− direction of a z-axis which is perpendicular to the x-y plane, the bending direction of the flexible apparatus 100 is a Z+ direction, and, when the bent flexible apparatus 100 curves in a z+ direction of the z-axis, the bending direction of the flexible apparatus is a Z− direction.
Accordingly, the strain gages may be embedded in the rear surface of the flexible apparatus 100 to detect bending of the flexible apparatus 100 in the Z− direction. However, such a configuration is merely an example and the strain gages may be embedded in one surface of the flexible apparatus 100 to detect bending in the Z+ direction and the Z− direction.
The sensor 120 may detect a degree of bending of the flexible apparatus 100, for example, a bending angle. The bending angle refers to an angle which is between an angle when the flexible apparatus 100 is in a flat state and an angle when the flexible apparatus 100 is bent.
Referring to
For example, when the flexible apparatus 100 is bent as shown in
As described above, the bending direction of the flexible apparatus 100 may be split into the Z+ direction or the Z− direction. The sensor 120 may detect the bending direction of the flexible apparatus 100 in various ways. A detailed description is provided with reference to
Referring to
For example, as shown in
Specifically, when the flexible apparatus 100 is bent in the Z+ direction as shown in
Accordingly, the controller 130 may detect the bending direction by comparing the resistance values of the two bend sensors 71 and 72 at the point A. For example, when the resistance value output from the lower bend sensor from among the two overlapping bend sensors is greater than that of the upper bend sensor at the same point, the controller 130 may determine that the flexible apparatus is bent in the Z+ direction. In addition, when the resistance value output from the upper bend sensor from among the two overlapping bend sensors is greater than that of the lower bend sensor at the same point, the controller 130 may determine that the flexible apparatus is bent in the Z− direction.
Although the two bend sensors are disposed overlapping each other on one side of the flexible apparatus 100 in
Referring to
Although the bending direction is detected using the two bend sensors in
Referring to
The sensor 110 may include a plurality of acceleration sensors which are disposed on edge areas of the flexible apparatus 100. The controller 130 may determine a bending direction of the flexible apparatus 100 based on a result of detecting by the sensor 120.
The acceleration sensors may measure acceleration of a motion and a direction of the acceleration. Specifically, the acceleration sensors output a detecting value corresponding to acceleration of gravity which changes according to a slope of an apparatus where those sensors are attached.
Accordingly, when the acceleration sensors 81-1 and 81-2 are disposed on opposite edges of the flexible apparatus 100 as shown in
In
In
The bending direction may be detected using a gyro sensor or a geomagnetic sensor besides the acceleration sensor. The gyro sensor refers to a sensor which, if a rotational motion occurs, detects an angular velocity by measuring Coriolis' force exerted in a velocity direction of the motion. Based on a measurement value of the gyro sensor, a direction of the rotational motion can be detected and thus a bending direction can also be detected. The geomagnetic sensor refers to a sensor which detects azimuth using a 2-axis or 3-axis fluxgate. When such a geomagnetic sensor is applied, the geomagnetic sensor disposed on each edge of the flexible apparatus 100 suffers from location movement when the edge is bent, and outputs an electric signal corresponding to a change in geomagnetism caused by the location movement. The controller 130 may calculate a yaw angle using the value output from the geomagnetic sensor. According to a change in the calculated yaw angle, various bending characteristics such as a bending area and a bending direction can be determined.
As described above, the controller 130 may determine bending of the flexible apparatus 100 based on a result of detecting by the sensor 110. The above-described configurations of the sensors and detecting methods may be applied to the flexible apparatus 100 individually, and may be applied in combination.
The bending holder 120 holds a bending state of the flexible apparatus 100. To achieve this, the bending holder 120 may include a plurality of polymer films which are disposed on a predetermined area of the flexible apparatus 100. In order to fix the overall area of the flexible apparatus 100 in the bending state, the plurality of polymer films may be disposed on the overall area of the flexible apparatus 100, and, in order to fix some areas of the flexible apparatus 100 in the bending state, the plurality of polymer films may be disposed on some areas of the flexible apparatus 100.
The controller 130 controls an overall operation of the flexible apparatus 100. In particular, the controller 130 may determine bending of the flexible apparatus 100 based on a result of detecting by the sensor 110. Specifically, the controller 130 may determine bending/unbending of the flexible apparatus 100, a location of a bending area, a location of the bending area, a size of the bending area, a number of bending areas, a size of a bending line, a location of the bending line, a number of bending lines, a bending direction, a bending angle, and a number of times that bending occurs, using the resistance values output from the bend sensors or the strain gages. This has been described above with reference to
When a predetermined input is received while the flexible apparatus 100 is bent, the controller 130 may control the bending holder 120 to hold the bending state of the flexible apparatus 100.
Specifically, when the flexible apparatus 100 is bent, the controller 130 stores information on the bending state in the flexible apparatus 100, and, when a predetermined input is received, the controller 130 controls to hold the bending state of the flexible apparatus 100 using the pre-stored information. The information on the bending state may include at least one of a bending area, a bending angle, and a bending direction of the flexible apparatus 100.
Referring to
For example, when a voltage of a predetermined level is applied to a polymer film 121 as shown in
In order to hold the flexible apparatus 100 in a constant state, the flexible apparatus 100 may pre-store information relating to which of the polymer films disposed in the flexible apparatus 100 a voltage is applied, an amount of voltage that should be applied to the polymer film, an order in which the voltage is applied to the polymer films, and/or the like (hereinafter, collectively referred to as control information). Accordingly, the controller 130 may apply a voltage to the polymer film to hold the bending state of the flexible apparatus 100 using the pre-stored control information.
Specifically, when the flexible apparatus 100 is bent, the controller 130 determines a location of a bending area, a bending angle, and a bending direction based on values detected by the sensor 110, and stores information on the determined bending state in the flexible apparatus 100.
Thereafter, when a user manipulation to hold the bending state of the flexible apparatus 100 is input, the controller 130 determines the bending state of the flexible apparatus 100 using the information on the bending state. The bending state may include at least one of the bending area, the bending angle, and the bending direction of the flexible apparatus 100.
The controller 130 determines a location of a polymer film to which a voltage is to be applied to hold the bending state of the flexible apparatus 100, a level of a voltage to be applied, and a voltage applying order, using the pre-stored control information, and applies a corresponding voltage to the polymer film and controls to hold the bending state of the flexible apparatus 100.
As an example for illustrative purposes, the left of the flexible apparatus 100 may be assumed to be bent by approximately 45° in the Z+ direction as shown in
In the above-described embodiment of the present disclosure, the five polymer films are provided. However, such a configuration is merely an example for convenience of explanation, and according to various embodiments of the present disclosure, the number and size of the polymer films may be changed according to a size of the flexible apparatus 100.
Also, in the above-described embodiment, the bending holder 120 includes the polymer films. However, in addition, or alternatively, the bending holder 120 may include a string, a piezoelectric element (e.g., a series bimorph piezoelectric element or parallel bimorph piezoelectric element), an Electro Active Polymer (EAP), an Electro Mechanical Polymer (EMP), and/or the like, and may hold the bending state of the flexible apparatus 100.
For example, when the bending holder 120 includes the string, the controller 130 may hold the bending state of the flexible apparatus 100 by changing a tensile force of the string. For example, when the shape of the flexible apparatus 100 is deformed by an external force, the flexible apparatus 100 is subject to a force of a reverse direction to return to the flat state due to the elasticity of the flexible apparatus 100. In this case, the controller 130 provides a physical force corresponding to the force of the reverse direction to the flexible apparatus 100, thereby holding the bending state of the flexible apparatus 100.
The user manipulation to hold the bending state of the flexible apparatus 100 may be input in various ways.
For example, when the flexible apparatus 100 is bent in the opposite direction to the bending direction of the flexible apparatus 100 within a predetermined time in the state in which the flexible apparatus 100 is bent, the controller 130 may control to hold the bending state of the flexible apparatus 100 using the pre-stored information.
For example, when the flexible apparatus 100 is bent in the Z+ direction and then is bent in the Z− direction within a predetermined time in the state in which the flexible apparatus 100 is bent, or when the flexible apparatus 100 is bent in the Z-direction and then is bent in the Z+ direction within a predetermined time in the state in which the flexible apparatus 100 is bent, the controller 130 may control to hold the bending state of the flexible apparatus 100.
To achieve this, when the flexible apparatus 100 is bent and then is re-bent within a predetermined time, the controller 130 may determine the bending direction of the re-bent flexible apparatus 100. When the bending direction of the flexible apparatus 100 is opposite to the bending direction of the re-bent flexible apparatus 100, the controller 130 may control the bending holder 120 to hold the bending state of the flexible apparatus 100.
Referring to
The center area is an area of a predetermined size that includes a center of the flexible apparatus 100. The edge area may be an area that excludes the center area of the flexible apparatus 100.
For example, as illustrated in
In addition, as illustrated in
In contrast, when a first bending manipulation is performed in a first direction in which one area of the flexible apparatus 100 curves upwardly or downwardly, and a second bending manipulation is performed on the other area in a second direction which is opposite to the first direction, the controller 130 may hold the bending state of the flexible apparatus 100.
The other area may be included in the bent area that is formed by bending one area of the flexible apparatus 100.
For example, as illustrated in
Further, as illustrated in
In the above-described embodiment of the present disclosure, when the flexible apparatus 100 is bent in one direction and then is bent in the other direction, the controller 130 may control to hold the bending state. However, such an operation is merely an example.
For example, according to various embodiments of the present disclosure, when a button manipulation to select a button provided on the flexible apparatus 100 is input or when the bending state is held for more than a predetermined time, the controller 130 may control to hold the bending state of the flexible apparatus 100.
As another example, according to various embodiments of the present disclosure, when a first bending manipulation is performed on the flexible apparatus 100 and then a second bending manipulation is performed in the opposite direction to that of the first bending manipulation after a predetermined time elapses, the controller 130 may control to hold the bending state of the flexible apparatus 100.
As another example, according to various embodiments of the present disclosure, when a touch manipulation to touch a display surface provided on the flexible apparatus 100 is input, the controller 130 may control to hold the bending state of the flexible apparatus 100. In this case, the flexible apparatus 100 may include a bendable display (not shown), and the sensor 110 may include a resistive or capacitive touch sensor to detect the touch manipulation on the display (not shown). Accordingly, the controller 130 may determine whether a user manipulation to hold the bending state of the flexible apparatus 100 is input or not based on an electric signal which is transmitted from the sensor 110.
As another example, according to various embodiments of the present disclosure, when a bending manipulation to bend a predetermined area of the flexible apparatus 100 is input, the controller 130 may control to hold the bending state of the flexible apparatus 100. For example, even when a bending manipulation is not performed in the opposite direction to the bending direction of the bent flexible apparatus 100, the controller 130 may control to hold the bending state of the flexible apparatus 100 when bending of a predetermined area of the flexible apparatus 100 is detected. The predetermined area may be set and changed by the user.
As example for illustrative purposes, the left upper area of the flexible apparatus 100 is assumed to be bent in the Z+ direction. In this case, when the right upper area of the flexible apparatus 100 is bent in the Z+ direction while bending is held, the controller 130 may control to hold the bending state in which the left upper area of the flexible apparatus 100 is bent in the Z+ direction.
According to various embodiments of the present disclosure, the controller 130 may control to hold the bending state of the flexible apparatus 100 based on a user's voice or motion.
Specifically, the controller 130 determines whether a voice collected by a voice collecting means provided on the flexible apparatus 100 such as a microphone (not shown) or the like is consistent with a predetermined voice command. When the collected voice is determined to be consistent with a voice command to hold the bending state of the flexible apparatus 100, the controller 130 controls to hold the bending state of the flexible apparatus 100.
The controller 130 analyzes an image of the user which is obtained through an image photographing means (not shown) provided on the flexible apparatus 100 such as a camera, and the controller 130 determines a user's motion gesture. Specifically, the controller 130 analyzes the image of the user. When the controller 130 determines that the user makes a motion gesture corresponding to a motion command to hold the bending state of the flexible apparatus 100, the controller 130 controls to hold the bending state of the flexible apparatus 100.
In contrast, when a predetermined input is not received while the flexible apparatus 100 is bent, the controller 130 may reset the information on the bending state that is stored in the flexible apparatus 100. The predetermined input may include a user manipulation to hold the bending state of the bent flexible apparatus 100, and for example, may include re-bending the flexible apparatus 100 in the opposite direction to that of the prior bending while the flexible apparatus 10 is bent.
According to various embodiments of the present disclosure, when a user manipulation other than the predetermined input, such as changing a bending angle of the flexible apparatus 100, returning the flexible apparatus 100 to the flat state, and re-bending the flexible apparatus 100 after the flexible apparatus 100 returns to the flat state, is input, the controller 130 may reset the information on the bending state that is stored in the flexible apparatus 100.
When the flexible apparatus 100 is bent by a first bending manipulation and a second bending manipulation is performed in the opposite direction to that of the first bending manipulation, but the second bending manipulation is performed after a predetermined time elapses after the first bending manipulation, the controller 130 may reset the information on the bending state that is stored in the flexible apparatus 100.
As described above, the controller 130 may store the information on the final bending state of the flexible apparatus 100 in the flexible apparatus 100. When the predetermined input is received while the flexible apparatus 100 is finally bent, the controller 130 may control to hold the final bending state of the flexible apparatus 100 using the information on the final bending state.
As an example, the flexible apparatus 100 may be assumed to be bent by a first bending manipulation and thereafter a second bending manipulation may be performed in the same direction as that of the first bending manipulation. In this case, the controller 130 resets information on the bending state that is stored when the first bending manipulation of the flexible apparatus 100 is performed, and stores information on the bending state of the flexible apparatus 100 when the second bending manipulation is performed. Thereafter, when a third manipulation is performed in the opposite direction to that of the second bending manipulation while the flexible apparatus 100 is bent by the second bending manipulation, the controller 130 may control to hold the state in which the flexible apparatus 100 is bent by the second bending manipulation.
However, the flexible apparatus 100 may have a property to return to the flat state due to the elasticity of the flexible apparatus 100. Therefore, when no external force is applied after the flexible apparatus 100 is bent by the first bending manipulation and thus the flexible apparatus 100 returns to the flat state, the controller 130 may perform only the operation of resetting the information on the bending state that is stored in the flexible apparatus 100. For example, the information on the bending state may not be separately stored.
In contrast, as described above, when the flexible apparatus 100 is bent by the first bending manipulation and then the second bending manipulation is performed in the opposite direction to that of the first bending manipulation, the controller 130 may control the bending holder 120 to hold the state in which the flexible apparatus 100 is bent by the first bending manipulation.
In this case, when a predetermined time elapses after the second bending manipulation has been performed, the controller 130 may control the bending holder 120 to hold the first bending state. The controller 130 may control the bending holder 120 to hold the first bending state in order to determine whether an intention of the user who performs the second bending manipulation is to hold the first bending state. Accordingly, when the second bending manipulation is canceled before the predetermined time elapses after the second bending manipulation has been performed, the controller 130 may determine that the second bending manipulation is not a bending manipulation to hold the first bending state, and may reset the information on the bending state that is stored when the first bending manipulation is performed. At this time, because the flexible apparatus 100 has a property to return to the flat state due to the elasticity of the flexible apparatus 100, the flexible apparatus 100 may return to the flat state when no external force is applied.
In the above-described embodiment of the present disclosure, the second bending manipulation is canceled before the predetermined time elapses after the second bending manipulation has been performed. However, this is merely an example. When a new bending manipulation is performed before the predetermined time elapses after the second bending manipulation has been performed, the controller 130 may reset the information on the bending state that is stored when the first bending manipulation is performed. In this case, the controller 130 may control to store the information on the final bending state of the flexible apparatus 100 according to the second bending manipulation.
When the flexible apparatus 100 is bent by the first bending manipulation and then the second bending manipulation is performed in the opposite direction to that of the first bending manipulation, but, when an area bent by the second bending manipulation is brought into contact with an area bent by the first bending manipulation, the controller 130 may reset the information on the bending state that is stored when the first bending manipulation is performed.
As an example, the left upper area of the flexible apparatus 100 may be assumed to be bent by about 90° in the Z+ direction, and then one area of the bent left upper area is bent in the Z− direction. At this time, when the one area of the left upper area is bent by about 180° in the Z− direction and thus the front surface and the rear surface of the flexible apparatus 100 are brought into contact with each other, the controller 130 may reset the information on the bending state that is stored when the first bending manipulation is performed.
The sensor 120 may include a touch sensor, a pressure sensor, and a proximity sensor to detect whether the front surface and the rear surface of the flexible apparatus 100 are brought into contact with each other, and the controller 130 may determine whether the front surface and the rear surface of the flexible apparatus 100 are brought into contact with each other based on the output values of these sensors.
The controller 130 may determine whether the front surface and the rear surface of the flexible apparatus 100 are brought into contact with each other using resistance values which are output from the bend sensors or strain gages. For example, the flexible apparatus 100 may pre-store the resistance values that are output from the bending line when the flexible apparatus 100 is bent by 180°, and, when the flexible apparatus 100 is bent and resistance values corresponding to the pre-stored resistance values are output from the bending line, the controller 130 may determine that the flexible apparatus 100 is bent by 180° and thus the front surface and the rear surface of the flexible apparatus 100 are brought into contact with each other.
In contrast, when an unfixing command is input while the flexible apparatus 100 is bent, the controller 130 may control the bending holder 120 to return the flexible apparatus 10 to the flat state. Specifically, when the unfixing command is input, the controller 130 may block the voltage applied to the polymer film and return the flexible apparatus 100 to the flat state. When the unfixing command is input, the controller 130 may reset the information on the bending state that is stored in the flexible apparatus 100.
The unfixing command may be input by at least one of a button manipulation to select a button provided on a body of the flexible apparatus 100 and a bending manipulation to bend a predetermined area of the flexible apparatus 100. The predetermined area may be set and changed by the user, and may be changed according to a location of an initially bent area.
For example, when the left area or the right area is initially bent with a reference to the center of the flexible apparatus 100, and the right area or the left area of the flexible apparatus 100 is bent, the controller 130 may determine that the unfixing command is input. In addition, when the upper area or the lower area of the flexible apparatus 100 is initially bent with reference to the center of the flexible apparatus 100, and the lower area or the upper area of the flexible apparatus 100 is bent, the controller 130 may determine that the unfixing command is input.
However, such a configuration is merely an example and a location of an area to be bent to input the unfixing command may be variously implemented.
As an example, according to various embodiments of the present disclosure, the controller 130 may return the fixed flexible apparatus 100 to the original flat state based on a user' voice or motion. For example, when a voice or a user's motion gesture which is collected is consistent with a command to release the bending state of the flexible apparatus 100, the controller 130 may return the flexible apparatus 100 to the flat state.
In addition, when an application installed in the flexible apparatus 100 is executed, the controller 130 may return the flexible apparatus 100 to the original flat state. The application recited herein refers to software that may be directly used by the user on an Operation System (OS), and may be provided in the form of an icon interface on a screen of a display (not shown) when the flexible apparatus 100 includes a bendable display (not shown). For example, the application may include an e-book application, a game application, a message application, and/or the like.
For example, when the user touches the display (not shown) and executes the application while the flexible apparatus 100 is bent and fixed, the controller 130 may return the fixed flexible apparatus 100 to the original flat state.

As a result, the display 140 is rolled in the body 310. The stopper may have a switch shape to stop an operation of a gear to rotate the rotary roller. Because the rotary roller and the stopper may employ a rolling structure according to the related art, a detailed illustration and explanation thereof are omitted.
According to various embodiments of the present disclosure, the body 310 includes a power supply (not shown). The power supply (not shown) may be implemented by using a battery connector on which a disposable battery is mounted, a secondary cell which can be charged and used multiple times by the user, and a solar cell which generates electricity using solar heat. When the power supply is implemented by using the secondary cell, the user may connect the body 310 to an external power source through a wire and may charge the power supply (not shown).

Thereafter, at operation S420, when a predetermined input is received while the flexible apparatus is bent, the bending state of the flexible apparatus is held.
Specifically, information on the bending state of the flexible apparatus is stored, and, when the predetermined input is received, the bending state of the flexible apparatus is held using the stored information. The information on the bending state may include at least one of a bending area, a bending angle, and a bending direction of the flexible apparatus. This has been described above with reference to
According to various embodiments of the present disclosure, when the flexible apparatus is bent and then is re-bent in a direction opposite to a direction in which the flexible apparatus is bent within a predetermined time, the bending state of the flexible apparatus is held.
For example, when a first bending manipulation is performed in a first direction in which a center area of the flexible apparatus curves upwardly or downwardly, and a second bending manipulation is performed on an edge area of the flexible apparatus in a second direction which is opposite to the first direction within a predetermined time, the bending state of the flexible apparatus is held.
In contrast, according to various embodiments of the present disclosure, when an unfixing command is input while the flexible apparatus is bent, the flexible apparatus may return to a flat state. The unfixing command may be input by at least one of a button manipulation to select a button provided on a body of the flexible apparatus and a bending manipulation to bend a predetermined area of the flexible apparatus. However, such a configuration should not be considered as limiting and the unfixing command may be input according to various methods.
According to various embodiments of the present disclosure, when the flexible apparatus includes a bendable display, and the flexible apparatus is fixed, a display area of the display may be split into a plurality of display areas according to the bending state of the flexible apparatus, and a screen may be displayed on each of the plurality of display areas. Such a configuration has been described above with reference to
According to various embodiments of the present disclosure, a non-transitory computer readable medium, which stores a program that performs the control method according to various embodiments of the present disclosure, may be provided.
