FIG. 1 shows the mobile terminal 100 having various components, but it is understood that implementing all of the illustrated components is not a requirement. Greater or fewer components may alternatively be implemented.
In the following description, the above elements of the mobile terminal 100 are explained in sequence.
First of all, the wireless communication unit 110 typically includes one or more components which permits wireless communication between the mobile terminal 100 and a wireless communication system or network within which the mobile terminal 100 is located. For instance, the wireless communication unit 110 can include a broadcast receiving module 111, a mobile communication module 112, a wireless internet module 113, a short-range communication module 114, a position-location module 115 and the like.
The broadcast receiving module 111 receives a broadcast signal and/or broadcast associated information from an external broadcast managing server via a broadcast channel.
The broadcast channel may include a satellite channel and a terrestrial channel.
The broadcast managing server generally refers to a server which generates and transmits a broadcast signal and/or broadcast associated information or a server which is provided with a previously generated broadcast signal and/or broadcast associated information and then transmits the provided signal or information to a terminal. The broadcast signal may be implemented as a TV broadcast signal, a radio broadcast signal, and a data broadcast signal, among others. If desired, the broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal.
At least two broadcast receiving modules 111 can be provided to the mobile terminal 100 in pursuit of simultaneous receptions of at least two broadcast channels or broadcast channel switching facilitation.
The broadcast associated information includes information associated with a broadcast channel, a broadcast program, a broadcast service provider, etc. And, the broadcast associated information can be provided via a mobile communication network. In this case, the broadcast associated information can be received by the mobile communication module 112.
The broadcast associated information can be implemented in various forms. For instance, broadcast associated information may include an electronic program guide (EPG) of digital multimedia broadcasting (DMB) and electronic service guide (ESG) of digital video broadcast-handheld (DVB-H).
The broadcast receiving module 111 may be configured to receive broadcast signals transmitted from various types of broadcast systems. By nonlimiting example, such broadcasting systems include digital multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcast-handheld (DVB-H), DVB-CBMS, OMA-BCAST, the data broadcasting system known as media forward link only (MediaFLO®) and integrated services digital broadcast-terrestrial (ISDB-T). Optionally, the broadcast receiving module 111 can be configured suitable for other broadcasting systems as well as the above-explained digital broadcasting systems.
The broadcast signal and/or broadcast associated information received by the broadcast receiving module 111 may be stored in a suitable device, such as a memory 160.
The mobile communication module 112 transmits/receives wireless signals to/from one or more network entities (e.g., base station, external terminal, server, etc.). Such wireless signals may represent audio, video, and data according to text/multimedia message transceivings, among others.
The wireless internet module 113 supports Internet access for the mobile terminal 100. This module may be internally or externally coupled to the mobile terminal 100. In this case, the wireless Internet technology can include WLAN (Wireless LAN) (Wi-Fi), Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access), etc.
The short-range communication module 114 facilitates relatively short-range communications. Suitable technologies for implementing this module include radio frequency identification (RFID), infrared data association (IrDA), ultra-wideband (UWB), as well at the networking technologies commonly referred to as Bluetooth and ZigBee, to name a few.
The position-location module 115 identifies or otherwise obtains the location of the mobile terminal 100. If desired, this module may be implemented with a global positioning system (GPS) module.
Referring to FIG. 1, the audio/video (A/V) input unit 120 is configured to provide audio or video signal input to the mobile terminal 100. As shown, the A/V input unit 120 includes a camera 121 and a microphone 122.
The camera 121 possesses a digital zoom and processes image frames of still pictures or video, which are obtained by an image sensor in a video call mode or a photographing mode. And, the processed image frames can be displayed on the display 151.
The image frames processed by the camera 121 can be stored in the memory 160 or can be externally transmitted via the wireless communication unit 110. Optionally, at least two cameras 121 can be provided to the mobile terminal 100 according to environment of usage.
The microphone 122 receives an external audio signal while the portable device is in a particular mode, such as phone call mode, recording mode and voice recognition. This audio signal is processed and converted into electric audio data. The processed audio data is transformed into a format transmittable to a mobile communication base station via the mobile communication module 112 in case of a call mode. The microphone 122 typically includes assorted noise removing algorithms to remove noise generated in the course of receiving the external audio signal.
The user input unit 130 generates input data responsive to user manipulation of an associated input device or devices. Examples of such devices include a keypad, a dome switch, a touchpad (e.g., static pressure/capacitance), a jog wheel, a jog switch, etc.
The sensing unit 140 provides sensing signals for controlling operations of the mobile terminal 100 using status measurements of various aspects of the mobile terminal. For instance, the sensing unit 140 may detect an open/close status of the mobile terminal 100, relative positioning of components (e.g., a display and keypad) of the mobile terminal 100, a change of position of the mobile terminal 100 or a component of the mobile terminal 100, a presence or absence of user contact with the mobile terminal 100, orientation or acceleration/deceleration of the mobile terminal 100. As an example, consider the mobile terminal 100 being configured as a slide-type mobile terminal. In this configuration, the sensing unit 140 may sense whether a sliding portion of the mobile terminal is open or closed. Other examples include the sensing unit 140 sensing the presence or absence of power provided by the power supply 190, the presence or absence of a coupling or other connection between the interface unit 170 and an external device. And, the sensing unit 140 can include a proximity sensor 141.
The output unit 150 generates outputs relevant to the senses of sight, hearing, touch and the like. And, the output unit 150 includes the display 151, an audio output module 152, an alarm unit 153, a haptic module 154, a projector module 155 and the like.
The display 151 is typically implemented to visually display (output) information associated with the mobile terminal 100. For instance, if the mobile terminal is operating in a phone call mode, the display will generally provide a user interface (UI) or graphical user interface (GUI) which includes information associated with placing, conducting, and terminating a phone call. As another example, if the mobile terminal 100 is in a video call mode or a photographing mode, the display 151 may additionally or alternatively display images which are associated with these modes, the UI or the GUI.
The display module 151 may be implemented using known display technologies including, for example, a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light-emitting diode display (OLED), a flexible display and a three-dimensional display. The mobile terminal 100 may include one or more of such displays.
Some of the above displays can be implemented in a transparent or optical transmittive type, which can be named a transparent display. As a representative example for the transparent display, there is TOLED (transparent OLED) or the like. A rear configuration of the display 151 can be implemented in the optical transmittive type as well. In this configuration, a user is able to see an object in rear of a terminal body via the area occupied by the display 151 of the terminal body.
At least two displays 151 can be provided to the mobile terminal 100 in accordance with the implemented configuration of the mobile terminal 100. For instance, a plurality of displays can be arranged on a single face of the mobile terminal 100 in a manner of being spaced apart from each other or being built in one body. Alternatively, a plurality of displays can be arranged on different faces of the mobile terminal 100.
In case that the display 151 and a sensor for detecting a touch action (hereinafter called ‘touch sensor’) configures a mutual layer structure (hereinafter called ‘touchscreen’), it is able to use the display 151 as an input device as well as an output device. In this case, the touch sensor can be configured as a touch film, a touch sheet, a touchpad or the like.
The touch sensor can be configured to convert a pressure applied to a specific portion of the display 151 or a variation of a capacitance generated from a specific portion of the display 151 to an electric input signal. Moreover, it is able to configure the touch sensor to detect a pressure of a touch as well as a touched position or size.
If a touch input is made to the touch sensor, signal(s) corresponding to the touch is transferred to a touch controller. The touch controller processes the signal(s) and then transfers the processed signal(s) to the controller 180. Therefore, the controller 180 is able to know whether a prescribed portion of the display 151 is touched.
Referring to FIG. 1, a proximity sensor (not shown in the drawing) can be provided to an internal area of the mobile terminal 100 enclosed by the touchscreen or around the touchscreen. The proximity sensor is the sensor that detects a presence or non-presence of an object approaching a prescribed detecting surface or an object existing around the proximity sensor using an electromagnetic field strength or infrared ray without mechanical contact. Hence, the proximity sensor has durability longer than that of a contact type sensor and also has utility wider than that of the contact type sensor.
The proximity sensor can include one of a transmittive photoelectric sensor, a direct reflective photoelectric sensor, a mirror reflective photoelectric sensor, a radio frequency oscillation proximity sensor, an electrostatic capacity proximity sensor, a magnetic proximity sensor, an infrared proximity sensor and the like. In case that the touchscreen includes the electrostatic capacity proximity sensor, it is configured to detect the proximity of a pointer using a variation of electric field according to the proximity of the pointer. In this case, the touchscreen (touch sensor) can be classified as the proximity sensor.
In the following description, for clarity, an action that a pointer approaches without contacting with the touchscreen to be recognized as located on the touchscreen is named ‘proximity touch’. And, an action that a pointer actually touches the touchscreen is named ‘contact touch’. The meaning of the position on the touchscreen proximity-touched by the pointer means the position of the pointer which vertically opposes the touchscreen when the pointer performs the proximity touch.
The proximity sensor detects a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch duration, a proximity touch position, a proximity touch shift state, etc.). And, information corresponding to the detected proximity touch action and the detected proximity touch pattern can be outputted to the touchscreen.
The audio output module 152 functions in various modes including a call-receiving mode, a call-placing mode, a recording mode, a voice recognition mode, a broadcast reception mode and the like to output audio data which is received from the wireless communication unit 110 or is stored in the memory 160. During operation, the audio output module 152 outputs audio relating to a particular function (e.g., call received, message received, etc.). The audio output module 152 is often implemented using one or more speakers, buzzers, other audio producing devices, and combinations thereof.
The alarm unit 153 is output a signal for announcing the occurrence of a particular event associated with the mobile terminal 100. Typical events include a call received event, a message received event and a touch input received event. The alarm unit 153 is able to output a signal for announcing the event occurrence by way of vibration as well as video or audio signal. The video or audio signal can be outputted via the display 151 or the audio output unit 152. Hence, the display 151 or the audio output module 152 can be regarded as a part of the alarm unit 153.
The haptic module 154 generates various tactile effects that can be sensed by a user. Vibration is a representative one of the tactile effects generated by the haptic module 154. Strength and pattern of the vibration generated by the haptic module 154 are controllable. For instance, different vibrations can be outputted in a manner of being synthesized together or can be outputted in sequence.
The haptic module 154 is able to generate various tactile effects as well as the vibration. For instance, the haptic module 154 generates the effect attributed to the arrangement of pins vertically moving against a contact skin surface, the effect attributed to the injection/suction power of air though an injection/suction hole, the effect attributed to the skim over a skin surface, the effect attributed to the contact with electrode, the effect attributed to the electrostatic force, the effect attributed to the representation of hold/cold sense using an endothermic or exothermic device and the like.
The haptic module 154 can be implemented to enable a user to sense the tactile effect through a muscle sense of finger, arm or the like as well as to transfer the tactile effect through a direct contact. Optionally, at least two haptic modules 154 can be provided to the mobile terminal 100 in accordance with the corresponding configuration type of the mobile terminal 100.
The projector module 155 is the element for performing an image projector function using the mobile terminal 100. And, the projector module 155 is able to display an image, which is identical to or partially different at least from the image displayed on the display 151, on an external screen or wall according to a control signal of the controller 180.
In particular, the projector module 155 can include a light source (not shown in the drawing) generating light (e.g., laser) for projecting an image externally, an image producing means (not shown in the drawing) for producing an image to output externally using the light generated from the light source, and a lens (not shown in the drawing) for enlarging to output the image externally in a predetermined focus distance. And, the projector module 155 can further include a device (not shown in the drawing) for adjusting an image projected direction by mechanically moving the lens or the whole module.
The projector module 155 can be classified into a CRT (cathode ray tube) module, an LCD (liquid crystal display) module, a DLP (digital light processing) module or the like according to a device type of a display means. In particular, the DLP module is operated by the mechanism of enabling the light generated from the light source to reflect on a DMD (digital micro-mirror device) chip and can be advantageous for the downsizing of the projector module 151.
Preferably, the projector module 155 can be provided in a length direction of a lateral, front or backside direction of the mobile terminal 100. And, it is understood that the projector module 155 can be provided to any portion of the mobile terminal 100 according to the necessity thereof.
The memory unit 160 is generally used to store various types of data to support the processing, control, and storage requirements of the mobile terminal 100. Examples of such data include program instructions for applications operating on the mobile terminal 100, contact data, phonebook data, messages, audio, still pictures, moving pictures, etc. And, a recent use history or a cumulative use frequency of each data (e.g., use frequency for each phonebook, each message or each multimedia) can be stored in the memory unit 160. Moreover, data for various patterns of vibration and/or sound outputted in case of a touch input to the touchscreen can be stored in the memory unit 160.
Moreover, the memory 160 is provided with a plurality of operating systems and applications dedicated to each of the operating systems. For instance, the operating systems can include Android based OS, Linux based OS, Windows Mobile based OS, Apple based OS and the like.
The operating systems are selectively drivable one by one or can be driven entirely and simultaneously, under the control of the controller 180.
The applications are driven according to a platform of each operating system. Each of the applications is provided to execute a specific function. And, the applications are displayed as icons on the screen. For instance, the applications provide various functions of compass, enhanced reality, camera, video player, music player, game, news, web browser and the like.
The applications can be provided as defaults in the memory 160 of the mobile terminal 100 or can be downloaded from a website or an external terminal.
The memory 160 may be implemented using any type or combination of suitable volatile and non-volatile memory or storage devices including hard disk, random access memory (RAM), static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic memory, flash memory, magnetic or optical disk, multimedia card micro type memory, card-type memory (e.g., SD memory, XD memory, etc.), or other similar memory or data storage device. And, the mobile terminal 100 is able to operate in association with a web storage for performing a storage function of the memory 160 on Internet.
The interface unit 170 is often implemented to couple the mobile terminal 100 with external devices. The interface unit 170 receives data from the external devices or is supplied with the power and then transfers the data or power to the respective elements of the mobile terminal 100 or enables data within the mobile terminal 100 to be transferred to the external devices. The interface unit 170 may be configured using a wired/wireless headset port, an external charger port, a wired/wireless data port, a memory card port, a port for coupling to a device having an identity module, audio input/output ports, video input/output ports, an earphone port and/or the like.
The identity module is the chip for storing various kinds of information for authenticating a use authority of the mobile terminal 100 and can include User Identify Module (UIM), Subscriber Identify Module (SIM), Universal Subscriber Identity Module (USIM) and/or the like. A device having the identity module (hereinafter called ‘identity device’) can be manufactured as a smart card. Therefore, the identity device is connectable to the mobile terminal 100 via the corresponding port.
When the mobile terminal 110 is connected to an external cradle, the interface unit 170 becomes a passage for supplying the mobile terminal 100 with a power from the cradle or a passage for delivering various command signals inputted from the cradle by a user to the mobile terminal 100. Each of the various command signals inputted from the cradle or the power can operate as a signal enabling the mobile terminal 100 to recognize that it is correctly loaded in the cradle.
The controller 180 typically controls the overall operations of the mobile terminal 100. For example, the controller 180 performs the control and processing associated with voice calls, data communications, video calls, etc. The controller 180 may include a multimedia module 181 that provides multimedia playback. The multimedia module 181 may be configured as part of the controller 180, or implemented as a separate component.

And, a second embodiment of the present invention relates to a process for displaying all OS dedicated screens within a single screen together.
In the following description, a first embodiment of the present invention is described with reference to FIGS. 5 to 8.
First Embodiment
According to a first embodiment of the present invention, while a dedicated screen of a specific first OS of all operating systems is displayed, if a command for a OS dedicated screen switching is inputted by a user, the controller 180 of the mobile terminal 100 switches the first OS dedicated screen to a dedicated screen of a second OS and then displays the second OS dedicated screen.
FIG. 5 is a flowchart of a process for displaying screens respectively dedicated to operating system in a manner of switching the dedicated screens to each other according to a first embodiment of the present invention.
FIGS. 6 to 8 are diagrams of screen configurations of a process for displaying screens respectively dedicated to operating system in a manner of switching the dedicated screens to each other according to a first embodiment of the present invention.
Referring to FIGS. 5 to 8, the controller 180 displays a specific first OS dedicated screen 310 among all operating systems provided to the memory 160 on the touchscreen 151 [S110].
In this case, the first OS dedicated screen 310 is a home screen including applications executable in a first OS environment. For example, FIG. 6 shows that first to fourth applications are included in the home screen.
The first OS dedicated screen 310 initially displayed on the touchscreen 151 can be set by a user. Alternatively, the first OS dedicated screen 310 can include an OS dedicated screen finally displayed before the driving of the screen of the touchscreen 151 is turned off. Alternatively, the first OS dedicated screen 310 can include an OS dedicated screen finally displayed before the driving of the mobile terminal 100 is turned off. Alternatively, the first OS dedicated screen 310 can include a dedicated screen most frequently used among the dedicated screens of the entire operating systems.
Before the first OS dedicated screen 310 displayed in the step S110 is displayed, the controller 180 simultaneously drives the entire operating systems provided to the memory 160 or can drive the first OS currently displayed on the touchscreen 151 only.
Subsequently, the controller 180 detects whether a command for switching the first OS dedicated screen 310 to a second OS dedicated screen 320 is inputted to the first OS dedicated screen 310 [S120].
In this case, the OS dedicated screen switching command, as shown in FIG. 6, can include a flicking touch having specific directionality (e.g., a right direction) inputted to the first OS dedicated screen 310, a long touch or a touch gesture having a preset pattern.
The OS dedicated screen switching command can include a preset key input provided to the user input unit 130 or a touch to an icon having a dedicated screen switching function of each OS assigned thereto. In this case, the icon is displayed on the first OS dedicated screen 310.
As a result of the detection in the step S120, if the command for switching the first OS dedicated screen 310 to the second OS dedicated screen 320 is inputted [S130], the controller switches the first OS dedicated screen 310 to the second OS dedicated screen 320 and then displays the second OS dedicated screen 320 [S140].
In this case, while the entire operating systems are simultaneously driven, if the switching command is inputted, the controller 180 stops displaying the first OS dedicated screen 310 by having the entire operating systems keep being driven and is then able to display the second OS dedicated screen 320.
In particular, while the entire operating systems keep being driven, the controller 180 suspends (i.e., deactivates) the display or the first OS dedicated screen 310 and activates the second OS dedicated screen 320. Therefore, the controller 180 is able to switch the first OS dedicated screen 310 to the second OS dedicated screen 320.
While the first OS among the entire operating systems is being driven, if the command for switching the first OS dedicated screen 310 to the second OS dedicated screen 320 is inputted, the controller 180 suspends the display of the drive-off first OS dedicated screen 310, drives the second OS, and then displays the second OS dedicated screen 320.
The controller 180 displays informations 310a, 320a and 330a respectively indicating the entire operating systems on the touchscreen 151, as shown in FIG. 6. Particularly, the controller 180 is able to control the information 310a corresponding to the currently display OS dedicated screen 310 to be displayed in a manner of being distinguished from the rest of the informations 320a and 330a. 
Referring to FIG. 6 (a), if the first OS dedicated screen 310 is displayed, the controller 180 displays the first information 310a corresponding to the first OS among the informations 310a, 320a and 330a in a manner that the first information 310a is distinguished from the second and third informations 320a and 330a. 
In this case, referring to FIG. 6, the informations 310a, 320a and 330a indicate the corresponding operating systems, respectively. And, each of the informations 310a, 320a and 330a indicates which one of the OS dedicated screens is currently displayed on the touchscreen 151.
In particular, a user can be aware that a specific OS dedicated screen is currently displayed on the touchscreen by looking at the informations 310a, 320a and 330a. 
Meanwhile, if a flicking touch in a specific direction is inputted as a switching command for the OS dedicated screen to the first OS dedicated screen 310 [FIG. 6 (a)], the controller 180 switches the first OS dedicated screen 310 to a second OS dedicated screen 320 in next order and then displays the second OS dedicated screen 320 [FIG. 6 (b)].
If the second OS dedicated screen 320 is displayed, the controller 180 controls the second information 320a corresponding to the second OS among the informations 310a, 320a and 330a to be displayed in a manner of being distinguished from the first information 310a and the third information 330a. 
Moreover, if a flicking touch in a specific direction is inputted again as a switching command for the OS dedicated screen to the second OS dedicated screen 320 [FIG. 6 (b)], the controller 180 switches the second OS dedicated screen 320 to a third OS dedicated screen 330 in next order and then displays the third OS dedicated screen 330 [FIG. 6 (c)].
Besides, if the second information 320a among the informations 310a, 320a and 330a is touched, the controller 180 switches the first OS dedicated screen 310 to the second OS dedicated screen 320 in next order and then displays the second OS dedicated screen 320 [not shown in the drawing].
Meanwhile, although FIG. 6 shows that the informations 310a, 320a and 330a are displayed within the OS dedicated screen, the informations 310a, 320a and 330a can be displayed on an indicator region of the touchscreen 151. In this case, the indicator region is the region in which icons for indicating operative statuses of the mobile terminal 100 are displayed. The indicator region is normally situated at the top side of the touchscreen 151 to indicate such information as antenna reception status, remaining battery level status, current hour, date and the like.
Referring to FIG. 7 and FIG. 8, the controller 180 is able to display informations 310b, 320b and 330b, each of which indicates a specific one of all operating systems is currently driven, on the touchscreen.
In particular, referring to FIG. 7 (a), the controller 180 drives all operating systems simultaneously and then controls the informations 310b, 320b and 330b indicating the driven statuses of the entire operating systems to be displayed within the first OS dedicated screen 310 that is initially displayed.
If a specific one (e.g., the second information 320b) of the informations 310b, 320b and 330b is touched [FIG. 7 (a)], the controller 180 is able to turn off the driving of the second OS corresponding to the second information 320b [FIG. 7 (b)]. After the driving of the second OS has been turned off, if the second information 320b is touched again, the controller 180 is able to drive the second OS again.
Meanwhile, although FIG. 7 shows that the informations 310b, 320b and 330ba are displayed within the OS dedicated screen, the informations 310b, 320b and 330b can be displayed on an indicator region of the touchscreen 151.
Referring to FIG. 8 (a), the controller 180 initially drives the first OS only, controls the informations 310b, 320b and 330b indicating the driven statuses of the entire operating systems to be displayed within the first OS dedicated screen 310, and controls the information 310b indicating the currently driven first OS among the informations 310b, 320b and 330b to be displayed by being distinguished from the second information 320b and the third information 330b. 
Meanwhile, if a flicking touch in a specific direction is inputted as a switching command for the OS dedicated screen to the first OS dedicated screen 310, referring to FIG. 8 (b), the controller 180 turns off the driving of the first OS, drives the second OS, stops displaying the first OS dedicated screen 310, and displays the second OS dedicated screen 320.
In doing so, the controller 180 controls the information 320b indicating the driven second OS to be displayed by being distinguished from the first information 310b and the third information 330b. 
Besides, if a flicking touch in a specific direction is inputted as a switching command for the OS dedicated screen to the second OS dedicated screen 320, referring to FIG. 8 (c), the controller 180 turns off the driving of the second OS, drives the third OS, stops displaying the second OS dedicated screen 320, and displays the third OS dedicated screen 330.
In doing so, the controller 180 controls the information 330b indicating the driven third OS to be displayed by being distinguished from the first information 310b and the second information 320b. 
In the above description, so far, the first embodiment of the present invention is explained in detail with reference to FIGS. 5 to 8.
