However, not all illustrated components are required. A mobile terminal may be implemented by more components than the illustrated components, or a mobile terminal may be implemented by fewer components.

Hereinafter, the components will be described in order.

The wireless communication unit 110 may include one or more components that allow wireless communication between the mobile terminal 100 and the wireless communication system or wireless communication between the mobile terminal 100 and a network on which the mobile terminal 100 is located. For example, the wireless communication unit 110 may include a broadcast receiving module 111, a mobile communication module 112, a wireless Internet module 113, a short range communication module 114, and a location information module 115 .

The broadcast receiving module 111 receives broadcast signals and / or broadcast-related information from an external broadcast management server through a broadcast channel. The broadcast channel may include a satellite channel and a terrestrial channel. The broadcast management server may refer to a server for generating and transmitting broadcast signals and / or broadcast related information, or a server for receiving broadcast signals and / or broadcast related information generated by the broadcast management server and transmitting the generated broadcast signals and / or broadcast related information. The broadcast-related information may refer to a broadcast channel, a broadcast program, or information related to a broadcast service provider. The broadcast signal may include a TV broadcast signal, a radio broadcast signal, a data broadcast signal, and a broadcast signal in which a data broadcast signal is combined with a TV broadcast signal or a radio broadcast signal.

Meanwhile, the broadcast related information may be provided through a mobile communication network, and in this case, it may be received by the mobile communication module 112.

The broadcast-related information may exist in various forms. For example, an EPG (Electronic Program Guide) of DMB (Digital Multimedia Broadcasting) or an ESG (Electronic Service Guide) of Digital Video Broadcast-Handheld (DVB-H).

The broadcast receiving module 111 receives broadcasting signals using various broadcasting systems. In particular, the broadcasting receiving module 111 may be a Digital Multimedia Broadcasting-Terrestrial (DMB-T), a Digital Multimedia Broadcasting-Satellite (DMB-S) Only Digital Broadcast-Handheld (DVB-H), Integrated Services Digital Broadcast-Terrestrial (ISDB-T), and the like. Of course, the broadcast receiving module 111 is configured to be suitable for all broadcasting systems that provide broadcasting signals as well as the digital broadcasting system described above.

The broadcast signal and / or broadcast related information received through the broadcast receiving module 111 may be stored in the memory 160.

In addition, the mobile communication module 112 transmits and receives radio signals to at least one of a base station, an external terminal, and a server on a mobile communication network. Here, the wireless signal may include various types of data depending on a voice call signal, a video call signal, or a text / multimedia message transmission / reception.

The wireless Internet module 113 is a module for wireless Internet access, and the wireless Internet module 113 can be built in or externally.

The short-range communication module 114 refers to a module for short-range communication. Bluetooth, radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), ZigBee, and the like can be used as the short distance communication technology.

The location information module 115 is a module for confirming or obtaining the location of the mobile terminal. One example is the GPS (Global Position System) module. The GPS module receives position information from a plurality of satellites. Here, the location information may include coordinate information indicated by latitude and longitude. For example, the GPS module can accurately calculate the current location according to the triangulation method by measuring the precise time and distance from three or more satellites and measuring three different distances. A method of obtaining distance and time information from three satellites and correcting the error by one satellite may be used. In particular, the GPS module can acquire latitude, longitude and altitude as well as three-dimensional velocity information and accurate time from the position information received from the satellite.

An audio / video (A / V) input unit 120 is for inputting an audio signal or a video signal, and may include a camera 121 and a microphone 122. The camera 121 processes an image frame such as a still image or a moving image obtained by the image sensor in the video communication mode or the photographing mode. Then, the processed image frame can be displayed on the display unit 151. [

The image frame processed by the camera 121 may be stored in the memory 160 or transmitted to the outside through the wireless communication unit 110. [ The camera 121 may be equipped with two or more cameras according to the configuration of the terminal.

The microphone 122 receives an external sound signal by a microphone in a communication mode, a recording mode, a voice recognition mode, or the like, and processes it as electrical voice data. The processed voice data can be converted into a form that can be transmitted to the mobile communication base station via the mobile communication module 112 when the voice data is in the call mode, and output. The microphone 122 may be implemented with various noise reduction algorithms for eliminating noise generated in the process of receiving an external sound signal.

The user input unit 130 generates input data for a user to control the operation of the terminal. The user input unit 130 may include a key pad dome switch, a touch pad (static / static), a jog wheel, a jog switch, and the like. Particularly, when the touch pad has a mutual layer structure with the display unit 151, which will be described later, it can be called a touch screen.

The sensing unit 140 senses the current state of the mobile terminal 100 such as the open / close state of the mobile terminal 100, the position of the mobile terminal 100, the presence or absence of user contact, the orientation of the mobile terminal, And generates a sensing signal for controlling the operation of the mobile terminal 100. For example, when the mobile terminal 100 is in the form of a slide phone, it is possible to sense whether the slide phone is opened or closed. Also, it is responsible for a sensing function related to whether or not the power supply unit 190 is powered on, whether the interface unit 170 is connected to an external device, and the like.

The interface unit 170 serves as an interface with all external devices connected to the mobile terminal 100. For example, a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, a port for connecting a device having an identification module, an audio I / O port, Video input / output (I / O) ports, earphone ports, and the like.

Here, the identification module is a chip that stores various information for authenticating the use right of the mobile terminal 100, and includes a user identification module (UIM), a subscriber identity module (SIM) ), A Universal Subscriber Identity Module (" USIM "), and the like. In addition, an apparatus having an identification module (hereinafter referred to as 'identification device') can be manufactured in a smart card format. Accordingly, the identification device can be connected to the terminal 100 through the port. The interface unit 170 receives data from an external device or receives power from the external device to transfer the data to each component in the mobile terminal 100 or to transmit data in the mobile terminal 100 to an external device.

The output unit 150 is for outputting an audio signal, a video signal, or an alarm signal. The output unit 150 may include a display unit 151, an audio output module 152, an alarm unit 153, and the like.

The display unit 151 displays and 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. If the mobile terminal 100 is in the video communication mode or the photographing mode, the captured image and / or the received image or UI and GUI are displayed.

Meanwhile, as described above, when the display unit 13 and the touch pad have a mutual layer structure to constitute a touch screen, the display unit 151 can be used as an input device in addition to the output device. The display unit 151 may be a liquid crystal display, a thin film transistor-liquid crystal display, an organic light-emitting diode, a flexible display, a three-dimensional display 3D display). In addition, there may be two or more display units 151 according to the embodiment of the mobile terminal 100. For example, the mobile terminal 100 may be provided with an external display unit (not shown) and an internal display unit (not shown) at the same time. The touch screen can be configured to detect the touch input position as well as the touch input area as well as the touch input pressure. In addition, the touch screen can be configured to detect not only the real-touch but also the proximity touch.

In this specification, the term "real-touch" refers to a case where a pointer is actually touched on the screen, and "proximity-touch" , But approaches a predetermined distance from the screen. In this specification, a pointer is a tool for touching or touching a specific portion of a displayed screen. For example, there are stylus fans and fingers.

Although not shown in the figure, various sensors may be provided in or near the touch screen to sense touch or proximity touch of the touch screen. Or various sensors for sensing touch or proximity touch of the touch screen may be disposed in the sensing unit 140. [

An example of a sensor for sensing the touch of the touch screen is a tactile sensor.

A tactile sensor is a sensor that senses the contact of a specific object to a degree or more that a person feels. The tactile sensor can sense various information such as the roughness of the contact surface, the rigidity of the contact object, and the temperature of the contact point.

In addition, a sensor for sensing the touch of the touch screen can sense a touch-drag. The term "touch drag" refers to a case where a touched point is moved while a touch is maintained. That is, it refers to a case in which the touch is held and dragged. The act of tapping a predetermined point of the display screen through the pointer to distinguish it from the touch drag may be referred to as "tap-touch ". In this case, a sensor (for example, a tactile sensor) that senses the touch can sense the drag direction of the touch drag, the drag speed, the drag length, and the like.

An example of a sensor for sensing the touch of the touch screen is a proximity sensor.

The proximity sensor refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or a nearby object without mechanical contact using the force of an electromagnetic field or infrared rays. Therefore, the proximity sensor has a considerably longer life than the contact-type sensor and its utilization is also quite high.

Examples of the proximity sensor 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.

Among them, the operation principle of the high-frequency oscillation type proximity sensor will be described. In the oscillation circuit, when the high frequency of the stationary wave is oscillated, the oscillation amplitude of the oscillation circuit is attenuated or stopped when the sensing object approaches the sensor sensing surface, These changes are converted to electrical signals to detect the presence or absence of the sensing object. Therefore, even if any non-metallic substance comes between the high frequency oscillation proximity sensor and the sensing object, the proximity switch can detect the sensing object to be detected without interference of the object.

The proximity sensor may be configured so as to detect the proximity of the pointer with a change of the electric field along the proximity of the pointer, if the touch screen is electrostatic. Accordingly, when the pointer is not actually touched on the touch screen but is located close to the touch screen, the position of the pointer and the distance between the pointer and the touch screen can be detected.

In addition, a 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. When the proximity distance of the pointer is within a predetermined distance range, it can be recognized as a proximity touch. Proximity means the distance between the screen and the pointer. In particular, proximity may mean the shortest distance between the screen and the pointer.

In the present specification, the term "a predetermined point on the screen is touched proximately" means that the pointer is located at a position on the space vertically corresponding to the predetermined point and is recognized as a proximity touch.

By using the proximity sensor, it is possible to detect proximity touch and proximity touch patterns (for example, proximity distance, proximity touch direction, proximity speed, proximity touch time, proximity touch position, proximity touch movement state, Information corresponding to the touch operation and the proximity touch pattern can be output on the touch screen. In this specification, proximity speed means the speed at which the pointer approaches the screen or the speed at which the pointer moves away from the screen. For example, the proximity sensor can sense proximity-drag drag direction, drag speed, drag length, and the like. The term " proximity-drag "refers to a case where the point of proximity touch is moved while the proximity touch is maintained. That is, the case of dragging in a state where the proximity touch is maintained.

The audio output module 152 outputs 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 152 outputs an acoustic signal related to functions (e.g., call signal reception sound, message reception sound, etc.) performed in the mobile terminal 100. [ The sound output module 152 may include a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying the occurrence of an event of the mobile terminal 100. Examples of events that occur in the mobile terminal include receiving a call signal, receiving a message, and inputting a key signal. The alarm unit 153 may output a signal for informing occurrence of an event in a form other than an audio signal or a video signal. For example, it is possible to output a signal in a vibration mode. When a call signal is received or a message is received, the alarm unit 153 can output a vibration to notify it. Alternatively, when the key signal is input, the alarm unit 153 can output the vibration by the feedback to the key signal input. The user can recognize the occurrence of an event through the above-mentioned vibration output. Of course, a signal for notifying the occurrence of an event may also be output through the display unit 151 or the audio output module 152.
