The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, when the mobile terminal is in the call mode, a UI (User Interface) or a GUI (Graphic User Interface) associated with a call is displayed. When the mobile terminal 100 is in the video communication mode or the photographing mode, the display unit 151 displays the photographed and / or received video or UI and GUI.

The display unit 151 may be a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display display, a 3D display, and an e-ink display.

Some of these displays may be transparent or light transmissive so that they can be seen through. This can be referred to as a transparent display, and a typical example of the transparent display is TOLED (Transparent OLED) and the like. The rear structure of the display unit 151 may also be of a light transmission type. With this structure, the user can see the object located behind the terminal body through the area occupied by the display unit 151 of the terminal body.

There may be two or more display units 151 according to the embodiment of the mobile terminal 100. For example, in the mobile terminal 100, a plurality of display portions may be spaced apart from one another, or may be disposed integrally with one another, and may be disposed on different surfaces, respectively.

Also, the display unit 151 may be configured as a stereoscopic display unit 152 for displaying a stereoscopic image.

Here, a stereoscopic image represents a 3-dimensional stereoscopic image, and a 3-dimensional stereoscopic image represents a progressive depth and reality in which objects are located on a monitor or a screen, It is an image that makes you feel the same as the space. 3D stereoscopic images are implemented using binocular disparity. The binocular parallax means a parallax caused by the position of two eyes away from each other. When two eyes see two different images and the images are transmitted to the brain through the retina and fused, the depth and real feeling of the stereoscopic image can be felt .

The stereoscopic display unit 152 may be applied to a three-dimensional display system such as a stereoscopic system (glasses system), an autostereoscopic system (no-glasses system), and a projection system (holographic system). The stereoscopic method, which is widely used in home television receivers, includes a Wheatstone stereoscopic method.

Examples of the autostereoscopic method include a parallax barrier method, a lenticular method, an integral imaging method, and a switchable lens method. The projection method includes a reflection type holographic method and a transmission type holographic method.

Generally, 3D stereoscopic images consist of left image (left eye image) and right image (right eye image).

In addition, the 3D thumbnail image can generate a left image thumbnail and a right image thumbnail from the left image and right image of the original image frame, respectively, and combine them to generate one 3D thumbnail image. In general, a thumbnail means a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated in this way are displayed on the screen with a difference of the left and right distance by the depth corresponding to the parallax between the left image and the right image, thereby exhibiting a stereoscopic spatial feeling.

The left and right images necessary for realizing the three-dimensional stereoscopic image can be displayed on the stereoscopic display unit 152 by a stereoscopic processing unit (not shown). The stereoscopic processing unit receives a 3D image and extracts a left image and a right image from the 3D image, or receives a 2D image and converts it into a left image and a right image.

On the other hand, when a display unit 151 and a sensor (hereinafter, referred to as 'touch sensor') that detects a touch operation form a mutual layer structure (hereinafter referred to as a 'touch screen' It can also be used as an input device in addition to the device. The touch sensor may have the form of, for example, a touch film, a touch sheet, a touch pad, or the like.

The touch sensor may be configured to convert a change in a pressure applied to a specific portion of the display unit 151 or a capacitance generated in a specific portion of the display unit 151 into an electrical input signal. The touch sensor can be configured to detect not only the position and area where the touch object is touched on the touch sensor but also the pressure at the time of touch. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

If there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like.

Referring to FIG. 1, a proximity sensor 141 may be disposed in an inner region of the mobile terminal or in the vicinity of the touch screen, which is surrounded by the touch screen. The proximity sensor 141 may be provided as an example of the sensing unit 140. The proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface or an object existing in the vicinity of the detection surface without mechanical contact using an electromagnetic force or an infrared ray. The proximity sensor 141 has a longer life than the contact type sensor and its utilization is also high.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. When the touch screen is electrostatic, it is configured to detect the proximity of the pointer by a change of the electric field along the proximity of an object having conductivity (hereinafter, referred to as a pointer). In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Hereinafter, for convenience of explanation, the act of recognizing that the pointer is positioned on the touch screen while the pointer is not in contact with the touch screen is referred to as "proximity touch & The act of actually touching the pointer on the screen is called "contact touch. &Quot; The position where the pointer is proximately touched on the touch screen means a position where the pointer is vertically corresponding to the touch screen when the pointer is touched.

The proximity sensor 141 detects a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, a proximity touch movement state, and the like). Information corresponding to the detected proximity touch operation and the proximity touch pattern may be output on the touch screen.

In the case where the three-dimensional display unit 152 and the touch sensor have a mutual layer structure (hereinafter referred to as a 'three-dimensional touch screen') or a three-dimensional sensor that detects the touch operation and the stereoscopic display unit 152 are combined with each other The stereoscopic display unit 152 may also be used as a three-dimensional input device.

The sensing unit 140 may include a proximity sensor 141, a three-dimensional touch sensing unit 142, an ultrasonic sensing unit 143, and a camera sensing unit 144 as an example of the three-dimensional sensor.

The proximity sensor 141 measures the distance between the sensing surface (for example, a user's finger or a stylus pen) to which the touch is applied without mechanical contact using the force of the electromagnetic field or infrared rays. The terminal recognizes which part of the stereoscopic image has been touched using the distance. In particular, when the touch screen is of the electrostatic type, the proximity of the sensing object is detected by a change of the electric field according to the proximity of the sensing object, and the touch on the three-dimensional is recognized using the proximity.

The stereoscopic touch sensing unit 142 senses the strength or duration of a touch applied to the touch screen. For example, the three-dimensional touch sensing unit 142 senses a pressure to apply a touch, and when the pressing force is strong, recognizes the touch as a touch to an object located further away from the touch screen toward the inside of the terminal.

The ultrasonic sensing unit 143 is configured to recognize the position information of the sensing target using ultrasonic waves.

The ultrasound sensing unit 143 may include, for example, an optical sensor and a plurality of ultrasound sensors. The light sensor is configured to sense light, and the ultrasonic sensor is configured to sense ultrasonic waves. Since light is much faster than ultrasonic waves, the time it takes for light to reach the optical sensor is much faster than the time it takes for the ultrasonic waves to reach the ultrasonic sensor. Therefore, it is possible to calculate the position of the wave generating source using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera sensing unit 144 includes at least one of a camera 121, a photo sensor, and a laser sensor.

For example, the camera 121 and the laser sensor are combined with each other to sense a touch of a sensing target with respect to a three-dimensional stereoscopic image. When the distance information detected by the laser sensor is added to the two-dimensional image photographed by the camera, three-dimensional information can be obtained.

As another example, a photosensor may be stacked on a display element. The photosensor is configured to scan the movement of the object proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of light change, thereby acquiring position information of the object to be sensed.

The audio output module 153 can output audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception mode, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, The sound output module 153 also outputs sound signals related to functions (e.g., call signal reception sound, message reception sound, etc.) performed in the mobile terminal 100. [ The sound output module 153 may include a receiver, a speaker, a buzzer, and the like.

The alarm unit 154 outputs a signal for notifying the occurrence of an event of the mobile terminal 100. Examples of events generated in the mobile terminal 100 include call signal reception, message reception, key signal input, touch input, and the like. The alarm unit 154 may output a signal for notifying the occurrence of an event by using a form other than the video signal or the audio signal, for example, vibration. The video signal or the audio signal may be output through the display unit 151 or the sound output module 153 so that the display unit 151 and the sound output module 153 may be classified as a part of the alarm unit 154 .

The haptic module 155 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 155 may be vibration. The intensity and pattern of the vibration generated by the hit module 155 can be controlled by the user's selection or setting of the control unit. For example, the haptic module 155 may combine and output different vibrations or sequentially output the vibrations.

In addition to the vibration, the haptic module 155 may be configured to perform various functions such as a pin arrangement vertically moving with respect to the contact skin surface, a spraying force or a suction force of the air through the injection port or the suction port, a touch on the skin surface, contact with an electrode, And various tactile effects such as an effect of reproducing a cold sensation using an endothermic or exothermic element can be generated.

Hereinafter, a control method for outputting a home screen image using the mobile terminal according to an embodiment of the present invention shown in FIG. 1 to FIG. 3 will be described in detail.

4 is a diagram illustrating an example of a mobile terminal for outputting a home screen screen according to an exemplary embodiment of the present invention.

The control unit 180 may output the home screen image to the display unit 151. [ The home screen screen may also be referred to as an idle screen, and the home screen page may be output on the display unit 151 when the mobile terminal 100 is in a standby state.

More specifically, the home screen screen may include at least one object, and the object may be an icon (icon) or a widget (wiget) of an application installed in the mobile terminal.

On the other hand, the home screen screen may be composed of a plurality of pages according to the user's selection or the number of applications installed in the mobile terminal 100, and at least one of the plurality of pages may be displayed on the display unit 151).

The home screen screen includes an identification information area in which identification information on a page output to the display unit 151 is displayed, a status information area in which status information of the mobile terminal 100 is displayed, Or the like.

In addition, the desktop (or background) may be output on the display unit 151 by setting the user selection or control unit 180, and the controller 180 controls the display unit 151 to display the home screen, (151). The wallpaper may not be displayed when a widget is displayed on the display unit 151, and the wallpaper displayed on the widget may be set separately from the wallpaper of the home screen.

Hereinafter, a mobile terminal according to an embodiment of the present invention for backing up and restoring the above-mentioned home screen screen will be described in detail with reference to FIG. 5 to FIG.

5 is a flowchart illustrating a method for restoring a home screen image in the mobile terminal 100 according to an embodiment of the present invention.

First, the controller 180 of the mobile terminal 100 determines whether the home screen image is edited (S110). The home screen screen includes objects such as icons and widgets and a desktop. If at least one of them is added, deleted, or changed to another, it can be determined that the home screen screen is edited. In addition, even if the positions of the objects included in the home screen are changed, it can be determined that the home screen is edited.

If the home screen screen is edited, the step of storing the home screen screen before being edited as a backup screen (S120) may be performed. The control unit 180 stores the date of storing the backup screen together with the backup screen, the objects included in the backup screen, the desktop, and information on the positions of the objects in the memory 160. In the case where the home screen screen before editing is composed of a plurality of pages, the backup screen is also composed of a plurality of pages, and information of each of the desktop, objects, and the objects is stored for each page.

In addition to the case where the screen is edited, the control unit 180 may also store a home screen screen as a backup screen in response to a command to store the home screen screen as a backup screen or according to a predetermined period.

Meanwhile, when receiving a user request (S130), the controller 180 may output the backup screens stored in the memory 160 (S140). The request of the user means a restoration request for restoring the home screen screen. For example, the request of the user can be inputted as a touch input for "restoration" included in the setting menu.

The control unit 180 may output at least one of the backup screens stored in the memory 160. [ Also, the latest home screen screen can be output together with the backup screens.

For example, the backup screens are output to the display unit 151 sequentially in accordance with the time stored in the memory 160, and output to the frame formed in a tiled shape, or the respective backup screens are sequentially stacked and output .

Next, when any one of the outputted backup screens is selected (S150), the step of restoring the home screen screen to any selected one (S160) may be performed. That is, when one of the backup screens is selected by touch input or the like, the control unit 180 can return the home screen screen to the state of the selected backup screen.

Restoring means restoring all objects in the backup screen to the state of the backup screen. That is, all the configurations that make up the home screen screen, such as applications, widgets, wallpaper, etc., are returned to the state of the backup screen.

As described above, according to the present invention, the mobile terminal can store the backup screens for the home screen screen, output the backup screens when requested by the user, and restore the home screen screen to any one selected backup screen Therefore, the user can conveniently return the home screen screen to the state of the backup screen. In particular, since the backup screens are output, the user can visually confirm the screen to be restored and select the backup screen to be restored. Thus, user convenience is increased.

FIG. 6 is a diagram illustrating a process of editing a home screen screen in the mobile terminal 100 according to the present invention.

If the user deletes or installs an application or widget, the home screen screen will be different from the previous one. In addition, the home screen screen may be edited as the desktop is changed, and the home screen screen may be edited as the position of the object included in the home screen screen moves.

In particular, as a user-centric interface evolves, users tend to install or delete widgets to suit the user's taste, and to change the location of applications from time to time.

However, in case the edited home screen image is unsatisfactory, in order to return to the original state, it is necessary to re-install the changed objects or to return the positions of the objects one by one.

For example, FIG. 6 illustrates a mobile terminal 100 according to an embodiment of the present invention. The home screen image is edited twice, and the first backup screen B1 ' It is shown that the second backup scree (hereinafter B2 ') is stored in the memory 160 and the most recent homescreen (HS') is set. For convenience of explanation, the home screen screen is composed of one page, but the present invention is not limited thereto.

('APP01', 'APP02', 'APP03') and one folder object ('FOLDER01') for three applications are displayed on the first backup screen B1, . ('APP01', 'APP02', 'APP03', 'APP04') and two folder objects ('FOLDER01' and 'FOLDER02') for the four applications are included in the second backup screen B2 , And the most recent home screen screen (HS) includes icons for two applications ('APP01', 'APP02') and widgets associated with the search. You can also see that the desktop is set up differently.

At this time, in order to return the latest home screen screen (HS) to the state of the second backup screen (B2), the user resets the desktop and deletes the deleted applications ('APP03', 'APP04' And folders ('FOLDER01', 'FOLDER02') and delete the widget associated with the search.

However, according to the mobile terminal according to the embodiment of the present invention, the user can omit the above-described process by simply selecting the backup screen. Hereinafter, a method of restoring using FIG. 7 will be described in detail.

FIG. 7 is a conceptual diagram for explaining the control method illustrated in FIG. 5 using the mobile terminal 100 shown in FIG.

The user may request to output the backup screens stored in the memory 160 using a setting window or a control menu (e.g., 'Restore').

The control unit 180 may output at least one of the backup screens stored in the memory 160 when the user's request to output the backup screens is input. For example, referring to FIG. 7, the latest home screen screen (HS), the second backup screen (B2), and the first backup screen (B1) may be output in a stepwise fashion.

The order in which the backup screens are output may vary depending on the setting, but may be output in the reverse order of time for the convenience of the user. At this time, the control unit 180 may output the graphic object SB together with the backup screens to provide convenience of search. The content related to the graphic object SB will be described below with reference to FIG.

Subsequently, when any one of the outputted backup screens (for example, B1) is selected, the home screen image is changed to any one selected (HS? B1). As the changes are made, the widgets and applications are automatically restored to the state of the backup screen, and all objects included in the backup screen are returned to the state of the backup screen. When a folder is restored, all objects contained in the folder are also restored.

By default, the home screen screen is completely restored to the selected backup screen. However, various settings for the restoration method may vary depending on the user's selection.

For example, it can be restored by adding a backup screen while maintaining the home screen screen before restoration. According to this method, when the home screen before restoration includes two pages and the backup screen includes three pages, the restored home screen includes a total of five pages.

As another example, it is possible to restore an application or a widget included only in the backup screen while maintaining the home screen screen before restoration. The restored object is added to the home screen before restoration. If there is no space to be added, a new page can be added to the home screen screen.

In another example, an application or widget can be restored without restoring it, only the location of the output objects. That is, it is possible to restore the position of the object to the position that was output from the backup screen only for the object common to the home screen screen before the restoration and the backup screen. In addition, only the desktop can be restored.

As described above, the restoration can be made so that everything is changed to the state of the selected backup screen, or only a part thereof is changed. This depends on the method set by the user through the setting menu or the like.

FIG. 8 is a diagram for explaining the graphic object SB shown in FIG.

The control unit 180 may output the graphic object SB together with the backup screens. Referring to FIG. 8A, the graphic object SB sets the latest home screen screen as a starting point, and terminates the backup screen in which the stored date among the backup screens stored in the memory 160 is oldest And a progress bar that is a point (PAST). That is, the graphical object SB takes time as a variable, and when one point of the graphic object SB is selected, a backup screen corresponding to the selected point can be selected.

In particular, when the touch input is continuously moved from the first point to the second point of the graphic object SB, at least one of the backup screens cascaded out according to the movement may disappear or appear. For example, when the touch input moves to the past time point, the nth backup screen located at the uppermost position disappears while expanding toward the user, and the (n-1) th backup screen located behind the disappearing backup screen may be output. On the contrary, when the touch input moves to the current point of view, the n-1th backup screen that has been output is reduced and moves backward, and the n-th backup screen may appear to come out of the window.

Also, when the touch input is canceled at one point of the graphic object SB, a backup screen corresponding to the canceled point can be selected, and the home screen screen can be restored with the selected backup screen.

Referring to FIG. 8 (b), the graphical object SB may be represented by a real metaphor such as a clock. As the clock hands (e.g., hour hand) of the clock are moved by the touch input, the backup screens output to the display unit 151 can be changed.

Hereinafter, a control method of outputting a restoration history according to restoration of a backup screen selected in the mobile terminal 100 according to an embodiment of the present invention will be described in detail.

9 is a conceptual diagram for explaining a method of outputting a restoration history in the mobile terminal 100 according to an embodiment of the present invention. FIG. 9 shows the mobile terminal 100 after the home screen image is restored to the first backup screen B1 in FIG.

Referring to FIG. 9, when the restoration is completed, the controller 180 may output a restoration history (hereinafter, referred to as 'RS'). The restoration history includes information of a changed object when there is an object changed on the home screen screen before and after restoration.

For example, when the latest home screen screen (HS) of FIG. 7 is compared with the restored first backup screen B1, an application (APP03) and a folder (FOLDER01) are newly created, You can see that the related widget has been deleted.

In other words, when there is nothing left before the restoration, or when something new before the restoration occurs, the control unit 180 can output the information of such application as the restoration history.

The user can acquire information related to the restoration by using the restoration history, and can selectively restore the restoration history for each application. For example, if the "restore" menu is selected for a widget associated with a search that is not included in the first backup screen B1, the controller 180 retains a widget associated with the search after restoration to the first backup screen B1 . For example, when the "delete" menu is selected for the object ("APP03") of the application contained only in the first backup screen B1, the control unit 180 returns to the first backup screen B1 "May not be restored.

In addition, the restoration history may include at least one of the name of the newly installed or deleted application, the total number of objects and changed applications, and the backup date of the backup screen.

10 is a conceptual diagram for explaining a method of outputting a home screen screen after restoration in the mobile terminal 100 according to an embodiment of the present invention.

Referring to FIG. 10, if a new object that was not present before restoration is included in the restored home screen image, the controller 180 can distinguish the new object from other objects and output the new object. For example, it is possible to divide the changed object by a method of outputting a marker indicating disappearance and disappearing the object, or displaying a different color.

Further, according to the embodiment disclosed herein, the above-described method can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .

The mobile terminal described above can be applied to not only the configuration and method of the embodiments described above but also all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments It is possible.
