Meanwhile, the mobile terminal 100 according to an embodiment of the present invention may include a display unit 151 having a curved shape (having a curved surface) as shown in FIG. Further, the terminal body in which the display unit 151 is disposed may be formed with a curved outer appearance. For example, the front surface of the terminal body on which the display unit 151 is disposed may be bent concavely, and the rear surface of the terminal body on which the display unit 151 is not disposed may be curved convexly.

That is, the front case of the terminal body is curved so that the front surface thereof is concave, and the display unit 151 can also be concavely curved so as to correspond thereto. That is, in this case, the front surface of the terminal has a curvature.

If the user wants to check the event occurring in the mobile terminal 100, the user may press the display unit 151 to check the event occurring in the mobile terminal 100, if the user does not operate the mobile terminal 100 directly, The mobile terminal 100 can be lowered in a direction toward the upper side. On the other hand, when the user turns the mobile terminal 100 upside down, that is, when the display unit 151 faces the floor, information about an event occurring in the mobile terminal 100 provided through the display unit 151 .

However, when the user places the mobile terminal 100 having a concave curvature on the specific floor as described above, the user can select any event that occurs in the mobile terminal 100 regardless of the direction in which the mobile terminal 100 is placed. . That is, when the display unit 151 is oriented in the upward direction, the mobile terminal 100 has a curvature, so that the mobile terminal 100 vibrates for a while to be in a horizontal state, 151) of the mobile terminal (100). In addition, when the direction in which the mobile terminal 100 is placed is the direction in which the display portion 151 faces the floor, both ends of the upper and lower ends of the mobile terminal 100 come into contact with the floor, In the horizontal state, since the display unit 151 has a curvature, the display unit 151 located on the front surface of the mobile terminal 100 may have a predetermined space between the display unit 151 and the floor without touching the floor.

At this time, the sensing unit 140 may sense the horizontal state of the mobile terminal 100 using the gyro sensor or the acceleration sensor. In particular, according to an embodiment of the present invention, the sensing unit 140 may recognize a face-down mode. The sensing unit 140 may further include an optical sensor so that when the direction in which the mobile terminal 100 is placed is the direction toward the bottom of the display unit 151, And the ambient light entering the space between the bottoms. Specifically, the brightness, color, and the like of the ambient light can be grasped through the optical sensor. In addition, as the display unit 151 emits light, light is emitted through the space, and information about an event occurring in the mobile terminal 100 can be provided to the user. In particular, the display unit 151 can partially output light only in a part of the entire displayable area. In addition, the partial area may be changed in position so that the user can change the user's direction in the face down mode described later. In addition, when the display unit 151 partially outputs light, the brightness, color, wavelength, etc. of the light may be differently output.

Also, according to an embodiment of the present invention, a touch sensor and a proximity sensor for detecting a user's touch gesture may be provided on the rear surface of the terminal body of the mobile terminal 100. [

The mobile terminal 100 according to an exemplary embodiment of the present invention includes a display unit 151 and a display unit 151. The display unit 151 includes a display unit 151, A control command can be received.

Hereinafter, embodiments related to a control method that can be implemented in the mobile terminal 100 constructed as above will be described with reference to the accompanying drawings.

For convenience of description, it is assumed that the mobile terminal 100 mentioned below includes at least one of the components shown in FIG. The mobile terminal 100 may include a display unit 151, a sensing unit 140, and a controller 180. The display unit 151 may include a display unit 151, a sensing unit 140, In some cases, the mobile terminal 100 according to the present invention may further include a proximity sensor 141. The present invention can be implemented more easily when the display unit 151 is implemented as the touch screen 151. The present invention will be described below assuming that the display unit 151 is the touch screen 151 do.

In this specification, a face down mode refers to a state in which the mobile terminal 100 is flipped over a specific floor. That is, when the touch screen 151 of the mobile terminal 100 is placed on a plane facing the bottom, the mobile terminal 100 is in the face down mode. The control unit 180 may determine whether the mobile terminal 100 is in the face down mode through the sensing unit 140. [

In particular, when the horizontal state of the mobile terminal 100 is detected through the sensing unit 140 for a predetermined time, the controller 180 determines that the mobile terminal 100 is in an inverted state, that is, Can be detected. For this, the sensing unit 140 may include a gyro sensor or an acceleration sensor.

However, even if the touch screen 151 of the mobile terminal 100 faces upward, it may be mistaken as a face down mode if the horizontal state is detected. Therefore, when the additional condition is satisfied according to the user setting or the manufacturer's intention, 100) is in the face down mode. The control unit 180 controls the upper and lower ends of the mobile terminal 100 through a sensing unit 140 in addition to sensing the horizontal state of the mobile terminal 100, When it is additionally detected that the mobile terminal 100 is in the face-down mode, it can be determined that the mobile terminal 100 is in face-down mode.

As another example of the additional condition for determining the face down mode, the control unit 180 controls the touch screen 151 of the mobile terminal 100 through the sensing unit 140, It is possible to determine that the mobile terminal 100 is in the face down mode when the brightness of the detected light corresponds to a predetermined range.

The control unit 180 may detect the face down mode of the mobile terminal 100 when a plurality of additional conditions shown in the above example are simultaneously satisfied according to the setting of the user or the manufacturer's intention. .

The control unit 180 may control the information on the specific event to be output through the touch screen 151 when a specific event occurs in the mobile terminal 100 when the mobile terminal 100 is in the face down mode. When the touch screen 151 has a concave curvature, there is a predetermined space between the touch screen 151 and the bottom. When the touch screen 151 emits light of various wavelengths, brightness, colors and patterns according to an event, the user confirms the information of the event by checking the wavelength, brightness, color and pattern of light leaking through the predetermined space Can be recognized.

In this specification, an event may mean an interrupt related to various functions of the mobile terminal 100. That is, when a signal is received through the wireless communication unit 110, an application scheduled to be executed within a predetermined time is executed, and the content of the running application is changed, a notification operation for a specific state of the mobile terminal 100 The event may have occurred in the mobile terminal 100.

For example, telephone, message, other data, reception of a signal, execution of an alarm operation, and the like correspond to an event of the mobile terminal 100. Also, when a song is terminated or changed in a running music player, or when a missed call notification window is displayed on the touch screen 151, an event may be generated in the mobile terminal 100.

Particularly, the preset event refers to an event preset by the user to cause the touch screen 151 to emit light in the face down mode of the mobile terminal 100, when a corresponding event occurs among various events that may occur in the mobile terminal 100 . When the user selects one of the events occurring in the mobile terminal 100 in the face down mode of the mobile terminal 100, that is, in a state where the touch screen 151 of the mobile terminal 100 faces the bottom, And the like.

In the present specification, the touch gesture refers to an input operation for the user to operate the mobile terminal 100 via the touch screen 151 or the sensing unit 140. The control unit 180 can recognize the touch gesture of the user inputted through the touch screen 151 or the sensing unit 140 as an operation command of the mobile terminal 100. [ The type of the touch gesture includes a tab operation, a flick operation, and a touch drag operation for drawing a specific trajectory to a specific point. In addition, the touch gesture may include a proximity touch when the mobile terminal 100 includes the proximity sensor 141, as described above. In particular, the touch gesture using the sensing unit 140 includes a touch gesture for generating sound in the vicinity of the mobile terminal 100 and a touch gesture for generating sound on the outer surface of the mobile terminal 100.

5 is an exemplary diagram illustrating a face-down mode of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 5, a state in which the mobile terminal 100 is not completely turned upside down is shown in FIG. 5 (a). At this time, only one arbitrary side of the mobile terminal 100 is in contact with the floor, and both ends are not in contact with the floor. In this case, the controller 180 does not detect the state of the mobile terminal 100 in the face down mode. On the other hand, in FIG. 5 (b), the mobile terminal 100 is completely turned upside down and the touch screen 151 faces the bottom. When the front surface of the mobile terminal 100 is bent concave, the upper and lower ends 501 and 503 of the mobile terminal are respectively in contact with the bottom. At this time, the sensing unit 140 may sense the horizontal state of the mobile terminal 100 for a preset time, and the controller 180 senses that the mobile terminal 100 is in the face down mode. As described above, the controller 180 may detect that the mobile terminal is in the face down mode in the case where there is additional sensing of the sensing unit 140 according to the user setting or the manufacturer's intention. Hereinafter, the sensing unit 140 used for sensing the face down mode of the mobile terminal 100 is referred to as a first sensing unit. The first sensing unit is a concept distinguished from a second sensing unit for sensing a user-specified direction, which will be described later.

The second sensing unit may include an acoustic sensor capable of sensing the ambient sound of the mobile terminal 100 and the sound generated through the touch gesture performed on the outer surface of the mobile terminal 100, . The second sensing unit may include a gyro sensor or an acceleration sensor capable of sensing vibrations generated through a touch gesture performed on the periphery or the outer surface of the mobile terminal 100. [ Meanwhile, when the mobile terminal 100 has a key for sensing a user-specified direction on the outer surface, the second sensing unit may sense the user-specified direction by sensing the key input.

6 is a diagram illustrating an example of a location where the display unit emits light in the face-down mode of the mobile terminal according to an exemplary embodiment of the present invention.

6 (a), the touch screen 151 has a concave curvature, and when both ends 501 and 503 of the mobile terminal 100 are in contact with the bottom, the touch screen 151 touches the bottom surface (601). ≪ / RTI > Since the light is scattered, the touch screen 151 can emit light not only to the space between the touch screen 151 and the bottom surface, but also to the periphery thereof. At this time, the touch screen 151 can emit light in the entire area or a part of the area. The user can recognize the event occurring in the mobile terminal 100 by checking the light emitted to the periphery of the touch screen 151. [

6B illustrates an example in which the mobile terminal 100 further includes a light emitting unit 603 that emits light according to an event on the side of the mobile terminal 100 so that the user can confirm an event occurring in the mobile terminal 100 . The light emitting unit 603 may emit light in at least a portion of at least one side of the mobile terminal 100 (605). Meanwhile, the light emitting unit 603 may be provided in the mobile terminal 100 in a touch screen format according to the manufacturer's intention, or may be provided simply as an element for light emission. When the user is located on a specific side of the mobile terminal 100, the control unit 180 can grasp the position of the user and control the light emitting unit 603 in the user direction to emit light. For example, in FIG. 6B, a direction 605 in which the light emitting unit 603 emits light may be a direction recognized by the control unit 180 as a user's position.

FIG. 7 is a flowchart illustrating an operation of a mobile terminal according to an exemplary embodiment of the present invention. FIG. 9 is a diagram illustrating a process in which a mobile terminal recognizes a sound and detects a user-specified direction according to an exemplary embodiment of the present invention .

Referring to Figs. 7 and 9, both ends 501 and 503 of the mobile terminal 100 are in contact with the floor while the mobile terminal 100 is turned upside down in Fig. 9 (a). The control unit 180 may sense the face down mode of the mobile terminal 100 through the first sensing unit as described above with reference to FIG. 5 (S701). 9B is an exemplary diagram for explaining an operation of setting a user-specified direction by causing a user to generate a specific sound 903 around the mobile terminal 100 through the touch gesture 901. FIG. Referring to FIG. 9B, the user generates a sound 903 with a touch gesture 901 on the right side of the mobile terminal 100. At this time, a method of generating sound through the touch gesture 901 is merely an example, and a sound can be produced with a tool such as a pen, or a user's voice or an external sound device can be used. The second sensing unit can recognize the sound generated in the vicinity of the mobile terminal 100 and can sense the direction in which the sound is recognized. At this time, the control unit 180 sets the direction in which the sound is sensed through the second sensing unit to a user-specified direction (S703). For example, in FIG. 9B, the second sensing unit recognizes the sound on the right side of the mobile terminal 100, and the controller 180 sets the right direction of the mobile terminal 100 in the user direction. 9 (b), the touch gesture 901 may generate vibration around the mobile terminal 100. [ That is, the sensing unit 140 can sense the vibration by the touch gesture 901 on the right side of the mobile terminal 100, and the controller 180 sets the right side of the mobile terminal 100 in the user- . In this case, the second sensing unit may include a gyro sensor or an acceleration sensor.

FIG. 9C is an exemplary diagram for explaining an operation of the mobile terminal 100 to output a notification so that the user can confirm the set direction when the user-designated direction is set. Referring to FIG. 9C, the touch screen 151 emits light toward the right side of the mobile terminal 100 (910). In this example, since the user direction is set to the right side of the mobile terminal 100, the controller 180 controls the touch screen 151 to emit light corresponding to the user direction. Thus, when the touch screen 151 emits light, the user can see that the user-designated direction is set to the right.

That is, the touch screen 151 emits light and scatters the light between the touch screen 151 and the bottom. In this case, the direction in which the light is scattered and emitted should correspond to a user-specified direction. In order to satisfy such a condition, the control unit 180 controls the specific area related to the user-designated direction to be emitted from among the entire area of the touch screen 151 so that the touch screen 151 can emit light in the user- . Also, the controller 180 may control the light to be emitted in a direction other than the user-specified direction.

8 is a flowchart illustrating an operation of a mobile terminal according to another embodiment of the present invention. 7 and FIG. 9, the controller 180 determines that the touch screen 151 has been moved from the mobile terminal 100 to the mobile terminal 100. However, 100 in the right and left directions. The control unit 180 senses the face-down mode of the mobile terminal through the first sensing unit (S701), and controls the touch screen 151 to emit light according to a preset event (S801). In this case, the entire area of the touch screen 151 may emit light and the entire area of the touch screen 151 may emit light so that the controller 180 may emit light in both right and left directions of the mobile terminal 100. [ A region close to the right and left sides of the mobile terminal 100 can be controlled to emit light.

A specific example of how the second sensing unit recognizes the sound and the controller 180 sets the user-specified direction will be described with reference to FIGS. 10 and 11. FIG.

In order to distinguish the direction in which the second sensing unit senses the sound in the mobile terminal 100 in the face mode in FIG. 10A, the phases 1005 and 1007 surrounding the terminal body of the mobile terminal 100, , Left 1001 and right 1003 directions. Each of the areas indicates an area where the second sensing unit can sense sound in each direction of the mobile terminal 100. In order to sense the direction in which the sound is generated, the second sensing unit may be provided in the mobile terminal 100 in the form of a plurality of sensors in an inner area adjacent to each side surrounding the mobile terminal 100. The area indicates an area where each sensor positioned in an inner area adjacent to each side can sense sound. When sound occurs at the boundary of the two areas, sound can be sensed through at least one of the sensors sensing the two areas. If there is no need to sense sound in the upper and lower regions 1005 and 1007 of the mobile terminal 100, the mobile terminal 100 may include a sensor for sensing the upper and lower regions 1005 and 1007 It may not. Hereinafter, in this specification, it is assumed that the region 1005 is the upward direction of the mobile terminal 100, the region 1007 is the downward direction, the region 1003 is the rightward direction, and the region 1001 is the leftward direction.

A case where sound occurs in a specific direction of the mobile terminal 100 will be described with reference to FIG. 10 (b). When the user generates the sound 903 with the touch gesture 901 in a specific direction of the mobile terminal 100, the second sensing unit in each direction of the mobile terminal 100 can sense the generated sound, 180 may set a user-designated direction corresponding to the sound sensed through the second sensing unit. When the sound 903 generated in the user's touch gesture 901 is sensed on the right side of the mobile terminal 100, the controller 180 sets the user-designated direction to the right direction. Conversely, when the sound 907 generated by the user's touch gesture 901 is detected on the left side of the mobile terminal 100, the controller 180 sets the user's direction to the left direction.

When the sound 905 generated by the user's touch gesture 901 is sensed at the upper side of the mobile terminal 100, the controller 180 may set the user's direction to the upward direction, When the mobile terminal 100 has a curvature in the up and down direction, the controller 180 can control not to set the up and down directions in the user-specified direction according to the user setting or the manufacturer's intention. Since the upper and lower ends of the mobile terminal 100 are in contact with the floor, if the user-specified direction is set in either the upward direction or the downward direction, even if the touch screen 151 emits light, This can be impossible. In this case, when the sound is sensed through the second sensing unit in either the upward or downward direction, the control unit 180 determines whether the sound sensing position of the right or left direction of the mobile terminal 100 is a user- Direction can be set. Even when the controller 180 does not include a sensor for sensing the upper and lower regions 1005 and 1007 of the mobile terminal 100, the same operation as described above can be performed.

For example, referring to FIG. 10A, when the position where the sound is detected through the second sensing unit in the upper region 1005 of the mobile terminal 100 is close to the right region 1003, Can set the custom orientation to the right. On the other hand, when the position where the sound is detected is close to the left 1001, the controller 180 can set the custom direction to the left. 9B, the second embodiment may be applied not only to an acoustic sensor that senses sound but also to a gyro sensor or an acceleration sensor that detects vibration.

On the other hand, when the user generates the sounds 903 and 907 from the right and left sides of the mobile terminal 100, respectively, the controller 180 can know the times when the second sensing parts sense the respective sounds Therefore, you can set the custom direction in the order detected. For example, when the sound 903 is detected through the second sensing unit, the right direction is set in the custom direction, and then, when the sound 907 is sensed through the second sensing unit, the custom direction is changed from right to left . At this time, when the right side is set in the first user setting direction, the controller 180 controls the touch screen 151 to emit light corresponding to the right direction, and when the user specifying direction is changed to the left, .

In the above example, if the unintended sound is generated in the direction opposite to the user-specified direction after the user-specified direction is set in the specific direction, the user-oriented direction can be changed regardless of the user's intention. In order to prevent this, the controller 180 may control the user to perform a user-specified direction locking function when a specific key input of the user input unit 130 is detected.

Alternatively, the control unit 180 may control the user-specified direction to not be changed by detecting a preset user-direction-locked input. For example, when the control unit 180 controls the touch screen 151 to emit light corresponding to a user-specified direction, the user can confirm the user-specified direction through the light emission. If the user generates sound again in the same user direction after the user orientation determination, the second sensing unit senses this, and the controller 180 can control the user to perform the user orientation locking function.

If the two sounds 903 and 907 are simultaneously sensed through the second sensing unit, the control unit 180 may control to output a notification indicating that the user-specified direction setting has failed. The notification may be output in various manners, for example, depending on the manner in which the touch screen 151 emits light in a specific color, the manner in which the mobile terminal 100 vibrates, or the manner in which the audio file is output, have.

11 (a) is an exemplary diagram for explaining a case where the sound sensed by the second sensing unit is human voice. The manner in which the controller 180 sets the user-specified direction is the same as that described in Fig. 10, even when the sound is a human voice. That is, when the user direction is set to the right side of the mobile terminal 100 by the voice 1101, the controller 180 controls the touch screen to emit light correspondingly thereto (910). At this time, if the voice 1103 is sensed through the second sensing unit, the controller 180 can change the user-designated direction to the left. In addition, the control unit 180 may control the user to set the user-designated direction using only the voice of the user of the mobile terminal 100. In this case, For this purpose, the user can input the voice of the user through the microphone 122 of the input unit 120, and can preset it as sound for setting the user-specified direction.

For example, if the user pre-sets the user's voice 1101 to sound for setting the user's direction, if the second sensing unit detects the user's voice 1101 after the presetting, It is determined whether or not the voice sentence of the set voice matches the voice sentence of the voice sensed through the second sensing unit. If it is determined that the gateways of the two voices coincide with each other within the predetermined range, the controller 180 sets the right direction of the mobile terminal 100 to the user direction. At this time, even if the voice 1103 of a person other than the user is sensed through the second sensing unit in the other direction, since the voice 1103 is different from the predetermined voice 1101, . When the user moves to the left of the mobile terminal 100 and the second sensing unit senses the user's voice, the controller 180 controls the user's direction to be changed to the left.

11B is an exemplary diagram for explaining the setting of the user-specified direction according to the attribute of the sound sensed by the second sensing unit. 11 (b), a description will be given of a method for setting a user-specified direction when sound is generated in a plurality of directions around the mobile terminal 100. FIG. If the second sensing portion of the mobile terminal 100 is relatively larger than the decibel of the sound 1105 sensed from the right side of the sound 1107 sensed from the left side, the controller 180 can set the custom direction to the right have. The control unit 180 can recognize the sound as a sound for setting a user-designated direction only when the sound sensed through the second sensing unit is equal to or higher than a predetermined decibel.

In addition, when the sound sensed by the second sensing unit corresponds to a specific frequency band, the controller 180 can recognize the sound as a sound for setting a user-specified direction. For example, when the second sensing unit senses the sound 1105 belonging to the predetermined frequency band and senses the sound 1107 that is out of the preset frequency band, the controller 180 controls the direction in which the sound 1105 is sensed Can be set to a custom orientation.

In addition, the second sensing unit can sense the sense of distance of the sound. For example, it is possible to sense sound coming close to a distant sound and sound coming from a fixed position. The control unit 180 may utilize the sound coming near by using the sensed distance of the sound or the sound provided at the fixed position as the sound for setting the user-specified direction.

FIG. 12 is an exemplary view illustrating a process in which a user-specified direction is set when sound is generated on an outer surface of a mobile terminal according to an exemplary embodiment of the present invention. Referring to FIG. 12, the controller 180 can set a user-specified direction, as described with reference to FIGS. 7 and 9, ) And (c), respectively. 12 is not set based on the sound generated in the periphery of the mobile terminal 100, but is based on the sound generated on the outer surface of the mobile terminal 100, Respectively.

12B is a view for explaining an operation of setting the user-specified direction by the controller 180 when the touch gesture 901 input from the user is performed in the specific area 1201 of the outer surface of the mobile terminal 100 Fig. The touch gesture may be performed on the outer surface of the mobile terminal 100, but a case in which the touch gesture is performed on the back surface of the mobile terminal 100 will be described.

In this embodiment, the second sensing unit may include a sensor capable of sensing sound generated from the outer surface of the mobile terminal 100. [ 12 (b) is a diagram illustrating a configuration in which a second sensing unit 1210 is positioned on the rear surface of the mobile terminal 100 to detect sound generated in a rear area of the mobile terminal 100, for example, In FIG. 12, it is illustrated that it is disposed on the rear surface of the mobile terminal. However, the present invention is not limited to this and may be disposed on the side surface. The sensor 1210 may further include a touch sensor depending on the material of the outer surface of the mobile terminal 100 and may include a proximity sensor when the mobile terminal 100 includes a proximity sensor. The sensor 1210 of the second sensing unit can sense the sound generated on the outer surface of the mobile terminal 100 regardless of the type and name of the sensor.

Referring to FIG. 12A, the controller 180 can sense the face-down mode of the mobile terminal 100 through the first sensing unit (S701) And can set a user-specified direction (S703). When the area 1201 where the sound is generated due to the touch gesture 901 being on the right hand side of the mobile terminal 100, the controller 180 can set the user direction to the right.

Hereinafter, with reference to FIG. 13A, a method of generating a sound on the outer surface of the mobile terminal 100 by a user to set a user-specified direction will be described.

13A shows a rear surface of the mobile terminal 100 in which a right region 1303 and a left region 1303 are distinguished. The case where the mobile terminal 100 is in the face down mode will be described as an example. When the user inputs the touch gesture 901 on the rear surface of the mobile terminal 100, the second sensing unit senses the sound generation in the area 1305 as the touch gesture 901 is performed. The controller 180 determines whether the area 1305 belongs to the right area 1303 or the left area 1301 of the mobile terminal 100. [ If it is determined that the area 1305 belongs to the right area 1303 of the mobile terminal 100, the controller 180 sets the custom direction to the right. Referring to (c) of FIG. 12, the controller 180 may control the touch screen 151 to emit light in a direction corresponding to the user-specified direction. That is, if the region 1305 belongs to the right region 1303 of the mobile terminal 100, the touch screen 151 emits light toward the right direction (1220).

13A is an exemplary diagram for explaining a method of setting a user-specified direction according to sound generated when a drag input is performed on a back surface of the mobile terminal 100 as a touch gesture. When the area 1310 where sound is generated by the drag input is the right side of the mobile terminal 100, the controller 180 can set the user direction to the right. In particular, if the touch gesture is a drag input, the controller 180 controls the touch screen 151 to emit light corresponding to the area when the second sensing unit senses that the sound continues for the dragged distance 1310 .

12 and 13A, a case where a user performs a touch gesture on the rear surface of the mobile terminal 100 and the sound generated through the touch gesture is sensed through the second sensing unit has been described. However, when the second sensing unit senses sound as well as when vibration is generated through the touch gesture and the second sensing unit senses such vibration, the controller 180 controls the vibration of the outer surface of the mobile terminal 100, The user may set the user direction according to the area. For example, as shown in FIG. 12B, when the user rubs the rear surface of the mobile terminal 100 with a touch gesture, or when the user moves When the user touches the rear surface of the terminal 100, the second sensing unit senses the vibration, and the controller 180 can set the user's specific direction in consideration of the area where the vibration is sensed. The sensing sensor may be a gyro sensor or an acceleration sensor.

FIG. 13B is a diagram for explaining a process of setting a user-specified direction using a physical key on an outer surface of a mobile terminal according to an embodiment of the present invention.

Referring to (a) of FIG. 13, the mobile terminal 100 may include a physical key 3100 on its rear surface. 13B is a front view of the physical key 3100 located on the rear surface of the mobile terminal 100 in a direction 501. When the user presses the physical key 3100 (3110) Respectively. 13B, the user presses the physical key 3100 in the right direction (3110), and the physical key 3100 is tilted to the right in a seesaw form. 13D, the controller 180 can set the user direction in the right direction of the mobile terminal 100. [ 13E, the user presses the physical key 3100 leftward (3110), and the physical key 3100 is tilted to the left in a seesaw form. 13 (b), the controller 180 can set the user direction to the left direction of the mobile terminal 100. FIG. 14 is a flow chart illustrating a method of moving the sound detected by the mobile terminal 100 according to an embodiment of the present invention. Or the display region according to the drag region. In FIG. 14, the mobile terminal 100 is in face-down mode, and the user-specified direction is set to the right. 14 (a) and 14 (b), a case where the length of sound to be sensed by the second sensing unit is different will be described. 14A, the user can generate sound on the right side of the mobile terminal 100 by using the touch gesture 901. If the touch gesture 901 is in the drag mode, the sound is moved from the drag start position to the end Position. The second sensing unit can sense the length of the sound movement, and the controller 180 can determine the length of the drag 1401 and 1403. Here, generating the length of the sound by the user with the touch gesture 901 becomes the display area setting operation of the touch screen 151. [ 9B, the second embodiment may be applied not only to an acoustic sensor that senses sound but also to a gyro sensor or an acceleration sensor that detects vibration.

FIG. 14B is an exemplary view for explaining how the light emitting area of the touch screen 151 changes according to the display area setting in FIG. 14A. Referring to FIG. 14B, for example, the second sensing unit may sense the movement of sound generated from the drag 1401 and the drag 1403, and the control unit 180 may detect each drag 1401, 1403 It is possible to control the touch screen to emit light according to the drag length. That is, when the second sensing unit senses sound from the drag 1401, the controller 180 determines the length of the drag 1401 and controls the touch screen 151 to emit light 1405 corresponding thereto. In addition, when sound is detected from the drag 1403, the controller 180 may determine the length of the drag 1403 and control the touch screen 151 to emit light corresponding thereto (1407). At this time, the controller 180 may control the touch screen 151 to emit light in a portion corresponding to the drag length, in a region corresponding to the user-specified direction.

14C is a diagram illustrating the touch screen 151 according to the length of the sound generated through the touch gesture 901 of the user in the vicinity of the mobile terminal 100 or the drag input performed by the user on the outer surface of the mobile terminal 100, Emitting device according to the second embodiment of the present invention. 14 (c), when the second sensing unit senses the length of the sound generated in the drag 1401, the controller 180 controls the touch screen 151 to emit light with a corresponding brightness, wavelength, 1409). When the second sensing unit senses the length of the sound generated by the drag 1403 which is relatively longer than the drag 1401, the control unit 180 controls the drag of the touch screen 151 by the drag 1401 It is possible to control the touch screen 151 to emit light 1411 with a brighter, larger wavelength, or a darker color than the light emission 1409.

14, the touch screen 151 emits light in a different area depending on the length of the sound generated by the touch gesture 901. However, when the touch gesture is displayed on the outer surface of the mobile terminal 100 And the sound is generated through it, the above description can be applied equally. That is, when a drag input is made to the outer surface of the mobile terminal 100 as a touch gesture, the second sensing unit may detect the length of the sound generated by the drag input, and the controller 180 controls the touch screen 151 Can be controlled so as to emit light in accordance with the length of occurrence.

As described above with reference to FIGS. 9C and 12C, when the user designation direction is set, the control unit 180 controls the touch screen 151 to emit light so that the user can confirm the direction. 7, when a predetermined event occurs in the mobile terminal 100 while the face-down mode of the mobile terminal 100 is being maintained, the controller 180 controls the touch- (Step S705).

15 is an exemplary view for explaining a light emitting mode of a display unit in a face down mode of a mobile terminal according to an embodiment of the present invention.

15 (a), 15 (b), 15 (c) and 15 (d) are diagrams for explaining a case where the controller 180 detects a preset event in the face down mode and is displayed on the touch screen 151 facing the floor This is an example of a screen. That is, when the user is not in face-down mode, the control unit 180 may control the event generated in the mobile terminal 100 to be displayed through the touch screen 151. However, in face-down mode, even if the control unit 180 detects a preset event in a state where the mobile terminal 100 is placed with the touch screen 151 facing the floor, the touch screen 151 displays information about the event It is not necessary to control so as to output. Accordingly, in the face-down mode, the controller 180 can control the touch screen 151 to minimize the information on the event so as to provide limited information to the user, thereby outputting only the partial region.

Particularly, FIG. 15A shows an area 1501 in which the touch screen 151 emits light when the user-specified direction is set to any one direction as shown in FIGS. 9C and 12C FIG. 15B is an example of displaying areas 1501 and 1503 in which the touch screen 151 emits light when there is no user-specified direction setting. FIG. The controller 180 may adjust the brightness or pattern of the light emitted through the touch screen 151 according to the type or number of preset events to be sensed. Accordingly, the areas of the areas 1501 and 1503 in which the touch screen 151 emits light can be enlarged or reduced.

FIG. 15C is an exemplary view for explaining a case where the area of the light emitting area of the touch screen 151 is controlled according to the number of predetermined events detected by the controller 180. FIG. The control unit 180 may control the light emission of a part of the touch screen 151 when the first preset event is sensed. At this time, when the second preset event is detected, the controller 180 adjusts the light emitting area of the touch screen 151 according to the first preset event, and controls the display of the number of times information as the number of times of occurrence of the event increases . That is, when the second preset event is detected, the control unit 180 may control the display unit 1505 to display the additional light emitting area 1505 accordingly. In addition, the controller 180 may control the light emitting area of the touch screen 151 to emit light by increasing the area of the touch screen 151 as the number of events is increased.

FIG. 15D is an exemplary diagram for explaining a case where the control unit 180 divides the light emitting region of the touch screen 151 into regions having different colors according to the types of preset events and emits light. 15D, when the first preset event occurs, the control unit 180 controls the touch screen 151 to emit light with a first color in the area 1507, and the second preset event And controls the touch screen 151 to emit light in the region 1509 with the second color. The controller 180 may control the two regions 1507 and 1509 to emit light at the same time, and may alternatively control the light emission to be performed at a predetermined time interval. The areas 1507 and 1509 can be further subdivided and divided according to the type and number of events, and the area can be changed.

The control unit 180 may control the touch screen 151 to emit light in a part of the area 1505 of the side area of the touch screen 151 according to the type of the preset event.

16 is an exemplary diagram for explaining that the display unit of the mobile terminal emits light according to a predetermined event according to an embodiment of the present invention.

16A is an example of a screen in which a reception information and a reception selection window are displayed through the touch screen 151 when a predetermined event is a telephone reception of the mobile terminal 100. [ If the call reception 1520 from a specific contact is a preset event, the control unit 180 checks whether the event is a preset event when a telephone reception event occurs. When the event corresponds to the preset event 1520, the touch screen 151 is controlled to emit light 1530 as shown in FIG. 16 (b). A case in which the touch screen 151 emits light is shown when the user-specified direction is not set as shown in Figs. 16 (b) to 15 (b). If the preset direction is set to the right side of the mobile terminal 100, if the preset event is generated, the controller 180 moves the touch screen in the right direction set in the user direction as shown in FIG. 15 (a) 151 can be controlled to emit light. This allows the user to know that a preset event has occurred.

FIG. 17A is an exemplary diagram for explaining that the display unit of the mobile terminal according to an exemplary embodiment of the present invention emits light according to the importance of an event. FIG. In particular, Figs. 17A, (b) and (c) are illustrations for explaining a case where there is no setting for the user-specified direction as described above with reference to Fig. 17A, in the face down mode of the mobile terminal 100, the controller 180 detects a predetermined event and controls the touch screen 100 to emit light in both directions (right and left) of the mobile terminal 100 do. At this time, the touch screen 151 may be displayed as shown in FIG. 15 (b).

Referring to FIGS. 17A, 17B, and 17C, the controller 180 may control the touch screen 151 to emit light with different brightness according to a predetermined event. The case where the preset event is a message reception from a specific source will be described as an example. The user may want to confirm the specific message and not want to confirm the other message when the user is in another work with the mobile terminal 100 turned upside down. Thus, the user can set the receipt of a message from a specific source that he wishes to confirm as a preset event. At this time, once the message is received, the control unit 180 determines whether the message reception corresponds to a preset event. As a result of the determination, if the event corresponds to a preset event, the control unit can control the touch screen 151 to emit light with a light brightness as shown in FIG. 17A.

Thereafter, when the user does not confirm the received message, if the same message is received twice from the same source, the control unit displays the touch screen 151 with the darker brightness than in FIG. 17A (a) . If the user does not confirm all the received messages twice and the message is received three times from the same caller, the control unit displays the touch screen 151 with a darker brightness than that of FIG. 17 (a) Can be controlled to emit light. The brightness of the light emitted by the touch screen 151 according to the number of unacknowledged received messages may be adjusted according to the user setting or the manufacturer's intention. Also, the controller 180 may control the brightness to be changed every time the user does not change the brightness each time the number of unacknowledged messages increases by one, as in the above example. In addition, if the user does not confirm the occurrence of the event even though the number of times of occurrence of the event is repeated, the mobile terminal 100 according to the present invention emits the touch screen 151 through the touch screen 151 on the bottom surface contacting the touch screen 151 It is possible to produce the same color as the light. That is, the controller 180 may detect the color of the floor on which the mobile terminal 100 is placed, and control the light to be emitted through the touch screen 151 in a color having a complementary color to the color of the floor. When the user does not confirm the event that occurs a plurality of times, the controller 180 gradually increases the color of the light emitted by the touch screen 151 and displays the light emitted by the touch screen 151 on the bottom surface The same visual effect can be generated. A method for the controller 180 to grasp the color of the bottom surface will be described later with reference to FIG. 28A.

On the other hand, in addition to receiving a message, if the user sets a reception of a signal from a specific source as a preset event, the signal may include all signals received from the same source, such as a telephone, message, messenger, and the like. For example, upon receiving a message once from a specific source corresponding to a predetermined event, the controller 180 may control the touch screen to emit light as shown in FIG. 17A. Thereafter, when the user receives one call from the same caller in an unacknowledged state, the controller 180 may control the touch screen to emit light with a darker brightness than that of FIG. 17A as shown in FIG. 17A (b) .

In addition, a case where the user sets a reception of a signal from a specific contact list, which is not a specific source, as a preset event will be described as an example. If there are three persons A, B, and C in the contact list, the control unit 180 controls the brightness of each of the contacts from the contacts to the brightness of (a), (b), It is possible to control the touch screen 151 to emit light. That is, the control unit 180 can control the touch screen 151 to emit light with different brightness for each person in the contact list.

In addition, the controller 180 may control the touch screen 151 to emit light with different brightness for each number of signal reception times from contacts present in the contact list. For example, when a message is received once from the contact A in the contact list, the control unit 180 can control the touch screen to emit light as shown in (a) of FIG. 17A. The control unit 180 controls the touch screen 151 to emit light as shown in (b) of FIG. 17A, and when receiving a message from the contact of B existing in the same contact list, the control unit 180 180 may control the touch screen 151 to emit light as shown in (c) of FIG. 17A. That is, the control unit 180 may control the touch screen 151 to emit light with different brightness for each number of signal reception times from the contacts belonging to the specific contact list.

The case where the touch screen 151 emits light with different brightness depending on the event has been described above. However, the touch screen 151 may emit light in at least one of a color, a pattern, and a wavelength according to an event.

For example, when each telephone is received from the contacts A, B, and C present in the contact list of the mobile terminal 100, the controller 180 determines whether the touch screen 151 is a ), 17A (b), and 17A (c). The user can preset the color output through the touch screen 151 when receiving a call for each contact existing in the contact list. The control unit 180 may control the touch screen 151 to emit light in a color corresponding to the contact preset by the user when the phone is received. Accordingly, the user can preview the contact by checking the color of the light emitted by the touch screen 151 when receiving the telephone call.

In addition, although FIG. 17A shows only the case where the user orientation is not set, when the user orientation is set, the controller 180 can control the touch screen 151 to emit light only in the user direction.

17B is an exemplary diagram illustrating a display pattern of a display unit when a mobile terminal receives a telephone call according to an embodiment of the present invention.

If the preset event is a telephone call to the mobile terminal 100, the control unit 180 can express the feeling of being received through the touch screen 151. [ Referring to FIGS. 17B, 17B, and 17B, when the controller 180 detects the reception of a telephone call, the wavelength of the light gradually spreads through the touch screen 151 You can control to display the diminishing pattern again. That is, when the phone is received, the controller 180 spreads the light emitted by the touch screen 151 to the outside direction 3200 of the mobile terminal 100 in (a) of FIG. 17 (b) The mobile terminal 100 can be controlled so that it spreads to a larger extent 3210 and decreases to the direction 3220 of the mobile terminal 100 as shown in (c) of FIG. Also, the control unit 180 can control such a pattern to be repeated.

18 is an exemplary diagram for explaining that the display unit of the mobile terminal emits light according to the number of events when the event according to the embodiment of the present invention is a signal reception. An example of a predetermined event in FIG. 18 (a) is an alert window informing the occurrence of a missed call from the VIP. Hereinafter, the case where the user-designated direction is right will be described as an example. If the user misses the call reception, the control unit 180 controls the touch screen 151 to display a notification window informing the missed call. However, when the mobile terminal 100 is in the face down mode, since the user does not directly see the touch screen 151, it may be difficult to confirm the notification window. The control unit 180 determines whether the missed call is a preset event.

For example, the user can create a VIP list in advance and set the event to be generated when a signal is received from the corresponding contact. If the user does not receive a call from the VIP and a missed call occurs, the control unit 180 may control the touch screen 151 to emit light. 18 (b) and 18 (c), the control unit 180 determines whether or not the touch screen 151 is on when the missed call from the VIP, which is the preset event, occurs once, . The control unit 180 controls the right user direction of the entire area of the touch screen 151 to emit light and controls some of the areas to emit light so as to correspond to the number of events. Accordingly, when the touch screen 151 emits light corresponding to the number of events once, the light is emitted to the bottom surface region 1710 (hereinafter referred to as the first region) where the mobile terminal 100 is placed . When the same event occurs again, the control unit 180 may control to enlarge an area where the touch screen 151 emits light by the number of times of occurrence of the same event so as to emit light. For example, when a missed call occurs twice from the VIP, the control unit 180 may control the touch screen 151 to emit light as shown in FIG. 18C. 18C shows a touch screen 151 (see FIG. 18B) as a region 1720 corresponding to twice the first area 1710 corresponding to the light emitting area of the touch screen at the time of one missed call shown in FIG. 18B. Is emitted from the light emitting layer.

In the above example, the case where the preset event is a missed call from the VIP has been described. However, even when the missed call is not received from the VIP but the call is received from the contact other than the VIP, ) May treat the contacts other than the VIP as the contacts of the VIP. The control unit 180 can check the transmission / reception pattern of the user even if the contact is other than the VIP, and treat the contact other than the VIP as a VIP contact when a phone call is continuously absent over a predetermined number of times. Or when the result of analysis of the transmission pattern of the user indicates that a missed call has occurred from the contact in the past and the time taken for the user to call the contact is very short as less than a predetermined time, If it is detected that the predetermined number of times has been exceeded, the control unit 180 may treat the contact as a VIP contact, not the VIP contact, and apply the above embodiment. When a missed call is generated from a contact addressable as a VIP contact or a VIP contact as described above, the user faces the user's ear when the user contacts the mobile phone 100. The control unit 180 controls the mobile phone 100 to make a call to the contact Can be controlled. The control unit 180 can control the wireless communication unit 110 to make a call to the corresponding contact by using at least one of the gyro sensor, the acceleration sensor, the altitude sensor, and the proximity sensor, have.

Also, the present embodiment can be applied to various cases in which the emission region can be varied depending on the number of times of occurrence of the missed call occurrence event.

FIG. 19 is an exemplary view for explaining that the display unit of the mobile terminal emits light according to the type of the event or the number of occurrences when the user direction is set to the right according to an embodiment of the present invention. In particular, referring to Figs. 19A, 19B, 19C and 19D, when a plurality of events occur in the mobile terminal 100 in the face-down mode, the touch screen 151 displays the color, Pattern, and luminescent region are different from each other.

19A and 19B, when the controller 180 senses the first preset event and the second preset event at different times, the controller 180 determines whether or not the event It is possible to control the touch screen 151 to emit light at different wavelengths as shown in (a) and (b) of FIG. In addition, when the controller 180 detects the second predetermined event while the touch screen 151 is emitting light in the first form as shown in FIG. 19 (a) by sensing the first predetermined event, , It is possible to control the touch screen 151 to emit light in the second mode in which the first mode is modified as shown in Fig. 19 (b). Alternatively, the controller 180 may control the touch screen 151 such that the first and second patterns emit light in a repeated pattern.

Embodiments in which the first form to the second form or the first form and the second form emit light in a repetitive pattern may be such that the first preset event and the second predetermined event are the same according to the user setting or the manufacturer's intention . ≪ / RTI > That is, the variation of the light emission pattern or the repetition of the pattern may provide the user with information on the number of times the same event occurs.

On the other hand, the above embodiment may be applied when the first predetermined event and the second predetermined event are different according to the user setting or the manufacturer's intention. That is, the variation of the luminescent pattern or the repetition of the pattern may provide information to the user that a different event has occurred.

Referring to FIG. 19C, the control unit 180 may control the touch screen 151 to emit light corresponding to the number of times of occurrence of the predetermined event, as in the description of FIG. The control unit 180 may sense the first preset event and control the area where the touch screen 151 emits light to be displayed in the first area 1830 of the bottom surface on which the mobile terminal 100 is placed. When the controller 180 senses the second pre-event while the touch screen 151 emits light in the first area, the touch screen 151 controls the second area 1833 to emit light . Here, although the first dictionary event and the second preset event have different kinds, the contents of the event may have a common point. For example, if the user has set the preset event to signal detection from a VIP belonging to a specific contact list, the first preset event may be a message reception and the second assessment setting event may be a telephone reception. That is, the event type is different, and the contact of the other party is the same. In this case, while the touch screen 151 is emitting light to the first area 1830 by sensing the first preset event, the controller 180 displays the second area 1833 The touch screen 151 may be controlled to emit light. The second region may be a region adjacent to the first region. The user can know from the emitted light 1830, 1833 that a plurality of times of contact has come from the same contact in the contact list.

In addition, the above example can be applied even when a message is received from different contacts belonging to the same contact list. For example, when a message is received from different contacts A and B belonging to the specific contact list, the controller 190 can control the touch screen to emit light as shown in FIG. 19C. The control unit 180 controls the touch screen 151 to emit light in the first area 1830 when a message is received from the contact A. [ If the message is received from the contact B while the first region 1830 is emitting light, the control unit 180 detects the message and displays the color and the color of the first region 1830 in the second region 1833 The touch screen 151 can be controlled so that light is emitted in the same color.

Referring to FIG. 19D, when the controller 180 detects a second pre-event different from the first pre-event while the touch screen is emitting light in the first area 1835, 180 may control the touch screen 151 to emit light as shown in FIG. 19 (d). That is, when the control unit 180 senses the second preset event, the touch screen 151 can control to emit light in a different region while maintaining the light emitting state of the light emitting region when the first preset event occurs have. Accordingly, the touch screen 151 emits light to the second region 1840 while emitting light to the first region 1835. At this time, the controller 180 may control the touch screen 151 such that different light is emitted in the first area 1835 and the second area 1840.

Here, the case where the first preset event and the second preset event are different kinds is described as an example. That is, when the controller 180 detects the first preset event and detects the second preset event different from the first preset event, the touch screen 151 emits light as shown in FIG. 19 (d) . However, (d) of FIG. 19 can be applied even when the same preset event occurs. For example, if the preset event is a missed call from the VIP, the control unit 180 may control the touch screen 151 to emit light into the first area 1835 when a first missed call occurs . If the three missed calls are detected from the VIP, the controller 180 controls the touch screen 151 to display the second region 1840 in a darker color than the color of the light emitted to the first region 1835 Can be controlled to be released.

FIG. 20 is a diagram illustrating an example in which a display unit of the mobile terminal emits light according to an amount of data transmission / reception when an event is data transmission / reception according to an exemplary embodiment of the present invention. 20 (a) and 20 (b) are for explaining the transmitting mobile terminal 100, and FIGS. 20 (c) and 20 (d) .

20A, when the user direction is on the right side and the mobile terminal 100 is transmitting a mail or uploading data, the controller 180 controls the data transmission state through the touch screen 151 Or to display the number of data to be transmitted. The control unit 180 may control the touch screen 151 to emit light in the areas 1910 and 1920 corresponding to the amount of data or the number of data to be transmitted in the transmission start step. Referring to FIG. 20B, the control unit 180 determines whether or not the transmission wait data excluding the amount (or number) of transmitted data among the entire areas 1910 and 1920 in which the touch screen 151 can emit light It is possible to control the touch screen 151 to emit light into an area 1910 corresponding to an amount (or number). At this time, the controller 180 may control the touch screen 151 not to emit light in the area 1920 corresponding to the amount of data already transmitted.

Referring to FIG. 20C, when the mobile terminal 100 is receiving mail or downloading data, the control unit 180 can control the data reception state to be displayed through the touch screen 151. That is, when the user direction is on the right side, the controller 180 can control the touch screen 151 not to emit light in a state where there is no data amount or data amount received in the data reception start step. 20D, the control unit 180 determines whether the touch screen 151 is illuminated by the touch screen 151 in the entire area 1910 or 1920 in which the touch screen 151 is capable of emitting light, The touch screen 151 can be controlled to emit light into the region 1920. At this time, the controller 180 can control the touch screen 151 not to emit light in the area 1910 corresponding to the amount of data waiting to be received.

20 (b) and 20 (d) can be applied to the case of data transmission / reception between the mobile terminals 100 as well. For example, FIG. 20 (b) illustrates an example of a mobile terminal that is transmitting data between mobile terminals performing mobile wireless LAN, and FIG. 20 (d) illustrates an example of a mobile terminal receiving data. As the data is transmitted, the area 1910 corresponding to the amount of transmission waiting data shown in FIG. 20B is reduced, and the area corresponding to the amount of received data shown in FIG. 20D is increased.

FIG. 21 is an exemplary diagram for explaining that the display unit of the mobile terminal emits light according to a music genre or a reproduction time when an event according to an embodiment of the present invention is music reproduction.

Referring to FIG. 21 (a), the controller 180 receives the input of the user and controls the player to reproduce music playing status information and music through the touch screen 151. At this time, in order to provide the reproduction state information of the music, the control unit 180 may control to display an area for visualizing the reproduction state of music currently being played, such as a music genre or a sound intensity have. In addition, the control unit 180 may control the player 2020 to operate the music playback operation through the touch screen 151. In Fig. 21 (a), a player capable of additionally providing information such as a song title, a reproduction time, and the like is shown as an example, in addition to being capable of operating a reproduction operation through a reproduction operation button.

Referring to FIGS. 21B and 21C, when the mobile terminal 100 is playing music through the player, the controller 180 detects it as a preset event, It is possible to control the touch screen 151 to emit light differently depending on the intensity of the music or the genre of the music or the reproduction time.

According to an embodiment of the present invention, for example, when a specific music is being reproduced through a music player, when the portion having a strong strong sound is being reproduced, the controller 180 determines whether the touch screen 151 is ), Or can emit light with a strong color or dark color.

In this case, the control unit 180 can control the touch screen 151 to emit light with a lighter hue as shown in (c) of FIG. 21 when the reproduction time ends.

According to an embodiment of the present invention, when the specific music being reproduced through the music player is strong beat music or dance music, the controller 180 determines that the touch screen 151 is strong as shown in FIG. 21 (b) Brightness, or dark color. If the music to be reproduced by the player is changed and the genre of the changed music is weaker than that of the specific music previously played back such as a ballad or a performance music, It is possible to control to emit light with a weaker brightness or a lighter hue than the case of (b) of Fig. 21 as in (c) of Fig.

Meanwhile, in the above embodiment, the control unit 180 controls the touch screen 151 to emit light with different colors or brightness. The control unit 180 may use the visualization area 2010 displayed on the touch screen 151. The control unit 180 controls the visualization area 2010 and the player 2020 of the music to be continuously displayed through the touch screen 151 even when the mobile terminal 100 is in the face down mode . At this time, the controller 180 may control the visualization area 2010 to display various visual effects through the touch screen 151 according to at least one of genre, sound intensity, or reproduction time of the music. Thus, the user can see the light emitted due to the visual effect between the touch screen 151 and the floor where the mobile terminal 100 is placed. The user can experience the visual effect of the music player even in the face down mode of the mobile terminal 100 without viewing the screen on which the music player is displayed through the front surface of the touch screen 151. [

The embodiment of the music player playback described with reference to FIG. 21 may be more effective when the speaker is located on the rear side of the mobile terminal 100 in the face-down mode mobile terminal 100. In addition, when the speaker is located on the rear side of the mobile terminal 100, when the preset event is a phone call through the speaker phone, the controller 180 controls the touch screen 151 Can be controlled to emit light. Also, the control unit 180 may control the touch screen 151 to emit light with different brightness or color as the talk time through the speaker phone elapses. For example, the control unit 180 may control the touch screen 151 to emit bright light gradually every ten minutes, as shown in FIG. 21, The control unit 180 may control the touch screen 151 to emit light corresponding to the set custom direction.

22 is an exemplary diagram for explaining that the display unit of the mobile terminal emits light when the event is music reproduction according to an embodiment of the present invention, in accordance with the music genre on the playlist.

Referring to FIG. 22 (a), the controller 180 receives a user input and controls the player 2020 to display the playlist 2030 and the music player 2020 through the touch screen 151. In particular, the control unit 180 can control the player to display the next scheduled play piece of the song being played back in the form of a list 2030.

Referring to FIG. 22B, the control unit 180 may control the light of a specific color 2031 to be emitted from a part of the touch screen 151 corresponding to the currently played song "Hotel California ". The user can thus know the genre of the music currently being played. In addition, the controller 180 may control the touch screen 151 to emit light corresponding to the genre of the music to be reproduced through the player. That is, adjacent to the area where the touch screen 151 emits light corresponding to the currently reproduced music, the control unit 180 controls a part of the touch screen 151 according to the genre of music existing in the play list 2030 It is possible to control light emission (2033, 2035) with different colors. In this way, the user can grasp the genres of music existing in the playlist in addition to the music currently being viewed.

  23 illustrates that when the event according to the embodiment of the present invention is performed in the face down mode of the mobile terminal 100, the display unit of the mobile terminal emits light with a different light emission area according to the duration of the face down mode Fig. When the user turns the mobile terminal 100 upside down, the mobile terminal 100 may enter the face down mode. According to the present embodiment, when the user is in a meeting or listening to a class, the user can obtain time information while maintaining the face down mode of the mobile terminal 100. Referring to FIGS. 23A and 23B, when the mobile terminal 100 enters the face-down mode, the controller 180 controls the touch screen 151 in response to the duration of the face- Can be controlled to emit light.

For example, the control unit 180 may control the touch screen 151 to emit light as shown in FIG. 23 (a) when 10 minutes have elapsed after the mobile terminal 100 enters the face down mode. 23A, the controller 180 can control the light emission of a part of the touch screen 151 according to the passage of the face down mode. Accordingly, the touch screen 151 can emit light to the area 2101 Can be released. Thereafter, when another 10 minutes have elapsed, the control unit 180 can control the touch screen 151 to emit light as shown in FIG. 23 (b). In FIG. 23B, the controller 180 can control the touch screen 151 to emit light in a wide area 2103 as compared with FIG. 23A. As described above, the time for the area of the touch screen 151 to emit light may be determined according to the user setting.

FIG. 23C illustrates that the touch screen 151 emits light in a continuous time sequence, unlike the case where the timer increases the light emitting area of the touch screen 151 every time unit set by the user Fig. Referring to FIG. 23C, the controller 180 may control the touch screen 151 to emit light in the continuous area 2015 corresponding to the duration of the face down mode. Thereby, the user can confirm the continuous time flow in which the face-down mode of the mobile terminal 100 is continued. When the control unit 180 detects the elapse of the predetermined time, the control unit 180 can control the area where the touch screen 151 emits light continuously and gradually in accordance with the detected time. The control unit 180 may control the area where the touch screen 151 emits light so that light is emitted to the entire continuous area 2015 after a predetermined time has elapsed. The timer function can be automatically executed by an execution command by the user's input or when the controller 180 detects the face down mode.

Meanwhile, the embodiment may be applied to all embodiments capable of adjusting the light emitting area of the touch screen 151 by measuring a specific amount that can be measured by the controller 180.

For example, in FIG. 23, when the preset event according to the present invention confirms the remaining power amount of the mobile terminal, the controller 180 controls the touch screen 151 to emit light with different emission regions according to the measured remaining power amount can do. Or when the preset event is the charge amount confirmation of the mobile terminal 100 when the mobile terminal 100 is charging. That is, the controller 180 can adjust the light emitting area of the touch screen 151 according to the amount of the charged mobile terminal 100. 23A, the area 2101 in which the touch screen 151 emits light expands to the area 2103 shown in FIG. 23B as the charge amount of the mobile terminal 100 increases, Can be. Also, as shown in FIG. 23C, the controller 180 may control the touch screen 151 to continuously display the increase in the charge amount of the mobile terminal 100.

Alternatively, when the preset event is multimedia playback, the controller 180 may control the touch screen 151 to emit light in different light emitting regions according to the playback time of the multimedia being played back. The control unit 180 associates the total reproduction time of the multimedia with the light emitting area of the touch screen 151, and the touch screen 151 emits light as shown in FIG. 23 (a) The light emitting region can be controlled to increase as shown in (b) of FIG. The flow of the reproduction time may be indicated by a continuous time flow as shown in (c) of FIG.

24 is an exemplary diagram for explaining that an event according to an embodiment of the present invention is a current time output and the display part of the mobile terminal inverts time information when the mobile terminal is placed on a specific floor surface. In the face down mode of the mobile terminal 100, when the control unit 180 controls the touch screen 151 to emit light, the emitted light may be reflected according to the material of the bottom surface. That is, when the bottom surface of the mobile terminal 100 is made of glass, when the touch screen 151 emits light, the emitted light can be reflected at a specific amount and a certain angle through the bottom surface of the glass material. Referring to FIG. 24A, when the controller 180 detects a predetermined event, the controller 180 controls the touch screen 151 to emit light. At this time, the light emitted by the touch screen 151 passes through the bottom surface 2200). The user can check the event of the mobile terminal 100 through the light leaking into the space between the touch screen 151 and the bottom surface 2200. However, the user can check the event of the mobile terminal 100 through the reflected light 2201, The user can obtain more specific information. The control unit 180 may determine the material of the floor surface 2200 on which the mobile terminal 100 is placed through the sensing unit 140. In particular, the sensing unit 140 may include an optical sensor, and the material of the bottom surface 2200 may be determined by measuring the reflectance of light emitted toward the bottom surface. The control unit 180 can control the display screen of the touch screen 151 to be inverted when the touch screen 151 emits light corresponding to the preset event when the reflectance of the predetermined range or more is measured.

FIG. 24B is an exemplary view for explaining a display screen inverted by the touch screen 151. FIG. When the user desires to confirm the current time information, the control unit 180 may control the current time information to be output through the touch screen 151 when a specific input is performed through the user input unit 130. [ However, when the face-down mode is in progress, the time information can not be confirmed through the front surface of the touch screen 151. 24 (a), when the light 2201 emitted by the touch screen 151 is reflected through the bottom surface 2200, the user can check the current time information through the reflected light 2201 have. Referring to FIG. 24B, in the face down mode, the controller 180 controls the current time to be inverted (2203) through the touch screen 151 and output. The controller 180 may control the touch screen 151 to emit light when the controller 180 senses a predetermined event even if the touch screen 151 faces the bottom surface in the face down mode. If the preset event is to detect a user input for confirming the current time value, the controller 180 may control the current time information to be output to a partial area of the touch screen 151. [ Particularly, when it is determined that the material of the bottom surface 2200 is reflected through the touch screen 151 as a result of sensing the material of the bottom surface 2200 through the sensing unit 140, It is possible to control the output to be inverted. At this time, the controller 180 determines the reflectivity of the bottom surface 2200, and controls the current time information to be displayed in a reversed manner on a part of the touch screen 151. [ In particular, the controller 180 may control the current time information of the touch screen 151 to be inverted and distorted according to the reflectance of the determined bottom surface 2200. That is, the controller 180 may control the display 2203 to change the appearance of the current time information such as the shape, color, brightness, size, and the like so that the bottom surface 2200 plays the role of the touch screen 151 . Referring to FIG. 24C, when the touch screen 151 displays the current time information 2203 in an inverted form, the current time information 2205 is formed on the bottom surface 2200 in a non- do. At this time, the formed image is reflected so that the user can check the non-inverted form of the current time information.

However, if the material of the bottom surface can reflect light emitted through the touch screen 151, it is not limited to the type of the preset event .

25 is a diagram illustrating an example in which the snooze function is activated by the sound generated by the touch gesture when the event is an alarm output according to an embodiment of the present invention and that the display unit of the mobile terminal emits light differently according to the snooze time .

Referring to FIG. 25 (a), the controller 180 can output an alarm and control the alarm screen to be displayed on the touch screen 151 when an alarm time preset by the user arrives. At this time, the alarm output is performed in the form of at least one of a sound output through the sound output module 152, a vibration output through the alarm unit 153, and an alarm output through the touch screen 151. The user can sense the alarm through the alarm output, terminate the alarm output by operating the function key 2310 displayed on the alarm output screen displayed on the touch screen 151, or activate the alarm snooze function. The alarm snooze function is a function for causing an alarm output to occur again after a predetermined time based on a preset alarm time. However, when the mobile terminal 100 is in face-on mode, the user can not operate the alarm output screen through the touch screen 151 even if an alarm output event is output through the touch screen 151. [ FIG. 25B is an exemplary diagram for explaining a method of activating the snooze function when the mobile terminal 100 is outputting an alarm in the face-down mode. Referring to FIG. 25 (b), the controller 180 may control the touch screen 151 to emit light in response to an alarm output event during the alarm output. At this time, the controller 180 can control the light to be emitted to both the right and left sides of the mobile terminal 100 as shown in FIG. 25 (B) It is possible to control the light emitting portion 2320 to emit light. When the user generates sound through the touch gesture on the outer surface of the mobile terminal 100 during the alarm output, the controller 180 can sense the sensed result through the second sensing unit and control the snooze function to be activated. Specifically, when the user generates sound through the touch gesture on the rear surface of the mobile terminal 100, the controller 180 activates the snooze function, and controls the area where the sound generated by the touch gesture is sensed, The snooze time of the snooze function can be controlled to be controlled in accordance with at least one of the snooze function and the snooze function. 17A, the controller 180 controls the touch screen 151 to emit light in at least one of color and brightness according to the adjusted snooze time so that the user can confirm the adjusted snooze time. have. In addition, as shown in FIG. 21, the controller 180 may control the touch screen 151 to emit light in a different region in which the light is emitted according to the adjusted snooze time. For example, when the snooze time is set to 5 minutes, the control unit 180 can control the touch screen 151 to emit light as shown in FIG. 23 (a). In addition, when the snooze time is set to 10 minutes, the controller 180 can control the touch screen 151 to emit light as shown in FIG. 23 (b).

25C is an example of an alarm output screen displayed on the touch screen 151 when sound is generated through the touch gesture on the rear surface of the mobile terminal 100 as described above. The controller 180 can activate the snooze function and adjust the snooze time by detecting sounds generated through the touch gesture on the rear surface of the mobile terminal 100 during the alarm output. At this time, it is possible to control the snooze setting 2330 to be displayed on the touch screen 151.

26 is an exemplary diagram for explaining that the display unit of the mobile terminal emits light differently according to the progress of recording when the event according to the embodiment of the present invention is executed in the voice recording operation.

26 (a) and 26 (b), when the preset event is the execution of the recording program, the controller 180 controls the recording program execution screen (2400) is displayed. When the user executes the recording program and turns the mobile terminal 100 upside down, the controller 180 detects the face down mode and causes the touch screen 151 to emit light 2410 and 2415 as shown in FIG. 26 (b) Can be controlled. Accordingly, the user can know that the mobile terminal 100 is performing recording. The control unit 180 may control the touch screen 151 to emit light of a specific color during a recording progress time so that the user can be notified that recording is still proceeding. Alternatively, the user may be able to confirm that the mobile terminal 100 is continuing recording, and may preset the mobile terminal 100 not to continuously emit light through the touch screen 151. At this time, the controller 180 may control the touch screen 151 to emit light at a predetermined time so that the user can recognize that the recording is continuing. For example, the control unit 180 may control the touch screen 151 to emit light every five minutes of the recording progress time. In addition, the controller 180 may control the light emission to be performed with different colors every specific time unit in which recording is performed. 26B shows an example in which the control unit 180 controls the touch screen 151 to emit light 2410 and 2415 in both directions of the mobile terminal 100 without setting the user's direction. If there is a user's direction setting to the right of the mobile terminal 100, the controller 180 may control the touch screen 151 to emit light 2410 to the right of the mobile terminal 100.

If the direction of the sound to be recorded is different from the user-specified direction when the control unit 180 recognizes the sound through the second sensing unit, the controller 180 records the user- It is possible to change the direction of the sound. In order to prevent such a change in the user-specified direction, the user-specified direction lock function described in the description of FIG. 10 may be used. Accordingly, when the user direction is set in a specific direction from the user and the user direction lock function is set, the controller 180 can fix the user direction in the corresponding direction. In this case, even if the direction of the sound to be recorded is different from the user-specified direction, the user can confirm the progress of recording in the user-specified direction as the touch screen 151 emits light. In addition to the custom direction lock, the user voice can also be preset to sound for custom direction setting as described above in the description of FIG. When the controller 180 detects a voice corresponding to a predetermined user's voice in a specific direction, the controller 180 sets the user-specified direction to the specific direction, and the user-specified direction is not changed even if sound recorded in the other direction is detected.

26C is an exemplary diagram for explaining a method of controlling the voice recording state using the sound through the touch gesture on the rear surface of the mobile terminal 100. [ Referring to FIG. 26C, when the touch gesture 901 is input to the rear surface of the mobile terminal 100, the controller 180 generates sound, detects the sound, can do. For example, when the user performs a tap input 901 of the touch gesture on the rear surface of the mobile terminal 100, the controller 180 senses the sound generated through the touch gesture and recognizes the sensed sound as a recording pause command To pause recording in progress. Also, if the tab 901 is inputted twice within a predetermined time, the controller 180 detects the generated sound, recognizes the sensed sound as a recording end command, ends the recording in progress, . On the other hand, if a touch gesture is inputted again after the touch gesture is inputted once after the sound is generated and the sound is generated again over the predetermined time, the controller 180 controls the pause have.

At this time, as shown in (c) of FIG. 26, the controller 180 controls the touch screen 151 to display at least one of color, brightness, and pattern differently according to an event such as recording pause and recording end, . Also, when the controller 180 resumes recording while pausing, the controller 180 may control the touch screen 151 to emit light as shown in FIG. 26 (b). That is, the controller 180 can control the touch screen 151 to emit light differently according to the type of the recording event, so that the user can check the progress of the recording.

FIG. 26 (d) is an example of a recording pause screen. Referring to FIG. 26 (d), when the recording which is in progress as shown in FIG. 26 (a) is suspended due to the recording program control using the sound through the touch gesture, the controller 180 controls the touch screen 151, It is possible to control so that the recording pause screen is displayed.

FIG. 27 is a diagram for explaining a method of displaying a notification of a display unit of a mobile terminal when an event according to an exemplary embodiment of the present invention is detected as a specific operation incomplete. When the user performs a specific task using the mobile terminal 100, the controller 180 may control the task window for performing the specific task to be displayed through the touch screen 151. [ In FIG. 27A, an edit window 2500 used when performing a text edit operation is shown as an example of a task window for performing a specific task. The editing window 2500 is divided into areas for different functions such as text editing, cropping, and copying. The control unit 180 may control the editing window 2500 to be displayed through the touch screen 151. [ At this time, if a touch gesture is input from the user to the area divided by the function of the edit window, the control unit 180 performs the corresponding edit operation. However, an editing operation through the editing window 2500 may require a subsequent operation. For example, the text editing function may require a post-modification storage operation, a cut function, and a copy function to cut or copy the text and paste it to another area. If the user does not follow up, the job is incomplete. When the mobile terminal 100 is in the face down mode, the controller 180 can control the touch screen 151 to emit light 2510 in a certain area as shown in FIG. 27 (b). The control unit 180 may control the touch screen 151 to emit light in at least one of color, brightness, wavelength, and pattern according to the type of the incomplete operation. In addition to the editing operation, the embodiment may be applied to the case where the control unit 180 detects an incomplete operation in a face down mode. For example, when the mobile terminal 100 performs data downloading or uploading operations and the user turns the mobile terminal 100 upside down, the controller 180 detects the face down mode. The controller 180 may control the touch screen 151 to emit light when the control unit 180 detects incomplete work due to data downloading or uploading failure during the data downloading or uploading operation. The user can recognize that there is an incomplete operation through the light emission of the touch screen 151. However, even if the user does not want to proceed with the subsequent operation during the above incomplete operation, if the touch screen 151 continuously emits light, user inconvenience may occur. In order to solve this problem, when a touch gesture is performed on a part of the area 2510 in which the touch screen 151 emits light corresponding to the incomplete operation as shown in FIG. 27 (b) And controls to cancel the job notification. 27 (d), the controller 180 controls the touch screen 151 so that the touch screen 151 does not emit light as shown in FIG. 27 (d) when sound is sensed by the user's touch gesture through the second sensing unit, have. The control unit 180 may control the touch screen 151 not to emit light as shown in (d) of FIG. 27, when not only the user's touch gesture but also an incomplete operation is completed by the user as shown in FIG. 27 (c).

FIG. 28A is an exemplary view for explaining a method of recognizing a color of a bottom surface of a mobile terminal according to an embodiment of the present invention. FIG.

28A is an example of a scene in which the user places the mobile terminal 100 on the floor surface 2550. FIG. That is, the user can move the upper end 503 to the floor while grasping the mobile terminal 100 (2555). At this time, the control unit 180 can detect the movement of the upper end 503 of the mobile terminal 100 through the gyro sensor or the acceleration sensor. If the movement locus 2560 of the upper end portion 503 is equal to or greater than a predetermined range of speed or distance, the controller 180 may detect that the mobile terminal 100 is in the face down mode. Referring to FIG. 28 (b), the mobile terminal (! 00) is in a state different from that of FIG. 28 (a) through the movement of the upper end 503. In this case, the controller 180 may detect that the mobile terminal 100 is proceeding to the face-down mode. Accordingly, the controller 180 may detect the color 2553 of the bottom surface 2550 using an optical sensor positioned on the front surface of the mobile terminal 100. The optical sensor may include an RGB sensor and an illuminance sensor. For this embodiment, the mobile terminal 100 may have a separate optical sensor on its front side, or a camera 121 located on the front side may be used instead of a separate optical sensor.

FIG. 28B is an exemplary view for explaining a feature of the display unit of the mobile terminal, which is one embodiment of the present invention, adjusting the color, brightness, and the like emitted according to the ambient light and outputting it. Referring to FIGS. 28B and 28B, when the mobile terminal 100 is placed on the bottom surface of the specific colors 2601 and 2605, The color of the surface can be detected. The sensing unit 140 may include an optical sensor, and the controller 180 may sense colors 2601 and 2605 of the bottom surface through an optical sensor. The method described in FIG. 28A can be used as a method for the controller 180 to detect the color of the bottom surface. At this time, when the controller 180 detects a preset event of the mobile terminal 100, the touch screen 151 emits light with hues 2603 and 2607 corresponding to the detected hues 2601 and 2605 Can be controlled. The control unit 180 may control the touch screen 151 to emit light in the corresponding colors 2603 and 2607 so as to be in contrast to the colors 2601 and 2605 of the respective bottom surfaces. For example, the colors 2601 and 2605 of each bottom surface and the colors 2603 and 2607 of the touch screen 151 may be complementary colors. For example, when the mobile terminal 100 is placed on the yellow floor, the control unit 180 can control the touch screen 151 to emit light of a complementary color of yellow, have.

The control unit 180 controls the brightness of the touch screen 151 according to the brightness of the ambient light 2609 and 2613 in the face down mode of the mobile terminal 100, So that the light emission can be controlled. The controller 180 may sense the brightness of the ambient light through the sensing unit 140, particularly the optical sensor. At this time, when the controller 180 detects a preset event, the touch screen 151 can control the touch screen 151 to emit light 2611 and 2615 corresponding to the brightness of the sensed ambient light. When the ambient light is bright, when the control unit 180 senses the preset event and controls the touch screen 151 to emit light, it may be difficult for the user to confirm the occurrence of the event if the touch screen 151 emits light. On the contrary, when the ambient light is dark, when the control unit 180 senses the preset event and controls the touch screen 151 to emit light, if the touch screen 151 emits light intensely, It is economical. Accordingly, the control unit 180 can control the touch screen 151 to light up (2611) so that the user can confirm occurrence of the preset event when the ambient light is bright (2609). The controller 180 may control the brightness of the touch screen 151 to be higher than the brightness of the ambient light measured through the sensing unit 140. [

In addition, the control unit 180 may control the touch screen 151 to light up (2615) so that the user of the dark side 2613 of ambient light can confirm the occurrence of the preset event. The controller 180 may control the brightness of the touch screen 151 to be at least brighter than the brightness of the ambient light measured through the sensing unit 140. [

For example, when the preset event is the power supply charging of the mobile terminal 100, the controller 180 detects that the mobile terminal 100 is charging the power, and controls the light emission of a part of the area of the touch screen 151 . At this time, the controller 180 may control the sensing unit 140 to detect brightness, color, and the like of ambient light. The control unit 180 may control the brightness of the light output from the touch screen 151 to be adjusted according to the brightness of the ambient light sensed through the sensing unit 140. [ The controller 180 may sense the brightness of ambient light through the sensing unit 180 and control the touch screen 151 to emit light as shown in FIG. 28 (c). That is, the controller 180 controls the brightness of the light output by the touch screen 151 to be brighter than the brightness of the ambient light so that the user can confirm that the mobile terminal 1000 is being charged.
