However, not all of the components shown are required components. 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 at least one component that enables wireless communication between the mobile terminal 100 and the wireless communication system or wireless communication between the mobile terminal 100 and the network in 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. WLAN (Wi-Fi), Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access) and the like can be used as wireless Internet technologies.

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. A typical example of the position information module 115 is a Global Position System (GPS) module. According to the present technology, the GPS module calculates distance information and accurate time information from three or more satellites, and then applies trigonometry to the calculated information to obtain three-dimensional current position information according to latitude, longitude, and altitude It can be calculated accurately. At present, a method of calculating position and time information using three satellites and correcting an error of the calculated position and time information using another satellite is widely used. In addition, the GPS module can calculate speed information by continuously calculating the current position in real time.

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 through 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, a 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 the sensing function related to the power supply of the power supply unit 190, whether the interface unit 170 is connected to an external device, and the like. Meanwhile, the sensing unit 140 may include a proximity sensor 141. This will be discussed later in connection with touch screens.

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 interface unit 170 may be a path through which power from the cradle is supplied to the mobile terminal 100 when the mobile terminal 100 is connected to an external cradle, Various command signals may be transmitted to the mobile terminal. The various command signals or the power source input from the cradle may be operated as a signal for recognizing that the mobile terminal is correctly mounted on the cradle.

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, and an alarm unit 153.

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 151 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). Some of these displays can be configured to be transparent so that they can be viewed from outside. This may be referred to as a transparent display. A typical example of the transparent display is a transparent organic light emitting diode (TOLED) or the like. 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 may be configured to detect not only the touch input position and area but also the touch input pressure.

Meanwhile, the proximity sensor 141 may be disposed inside or near the touch screen. 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. Therefore, the proximity sensor 141 has a considerably long life span and its utilization is also significantly higher than that of the contact-type sensor.

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.

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, This change is converted into an electrical signal to detect the presence or absence of a 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 141 may be configured so as to detect the proximity of the pointer with the 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. Hereinafter, for the sake of convenience of description, the act of allowing the pointer to be located on the touch screen to recognize that the pointer is positioned on the touch screen is referred to as "proximity touch ", and a pointer The actual touching action will be referred to as "contact touch. &Quot; 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.

The proximity sensor 141 detects proximity touches and proximity touch patterns (e.g., proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, and the like) , And may output information corresponding to the detected proximity touch operation and the proximity touch pattern on the touch screen.

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 call signal reception, message reception, key signal input, touch input, and the like. The alarm unit 153 may output a signal for notifying the 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 the 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 vibration output as described above. Of course, a signal for notification of occurrence of an event may also be output through the display unit 151 or the sound output module 152.

The memory 160 may store a program for processing and controlling the control unit 180 and may store a function for temporarily storing input / output data (e.g., a phone book, a message, a still image, . In addition, the memory 160 may store data on vibration and sound of various patterns outputted when a touch is input on the touch screen.

The memory 160 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory), a RAM (Random Access Memory) SRAM (Static Random Access Memory), ROM (Read Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM (Programmable Read- And an optical disc. Also, the mobile terminal 100 may operate a web storage for performing a storage function of the memory 160 on the Internet.

The control unit 180 typically controls the overall operation of the mobile terminal. For example, voice communication, data communication, video communication, and the like. In addition, the control unit 180 may include a multimedia module 181 for multimedia playback. The multimedia module 181 may be implemented in the control unit 180 or may be implemented separately from the control unit 180. [

The controller 180 may perform a pattern recognition process for recognizing handwriting input or drawing input performed on the touch screen as characters and images, respectively.

The power supply unit 190 receives external power and internal power under the control of the controller 180 and supplies power necessary for operation of the respective components.

Therefore, the present invention is not limited to a slider type mobile terminal but can be applied to all types of mobile terminals including the above-mentioned type.

2 is a perspective view of a mobile terminal according to an embodiment of the present invention.

The mobile terminal 100 of the present invention includes a first body 200 and a second body 205 configured to be slidable along at least one direction on the first body 200. In the case of a folder phone, the mobile terminal 100 may include a first body and a second body configured to fold or unfold at least one side of the first body.

The state where the first body 200 is disposed in a state of being overlapped with the second body 205 may be referred to as a closed configuration and the first body 200 may be referred to as a second body 205 ) May be referred to as an open configuration.

Although the terminal according to the folder type and the swing type is not described in detail, it will be understood by those skilled in the art that a detailed description thereof will be omitted.

The mobile terminal 100 mainly operates in the standby mode in the closed state, but the standby mode is also released by the operation of the user. The mobile terminal 100 operates mainly in a communication mode in an open state, but is also switched to a standby mode by a user's operation or a predetermined period of time.

The casing (casing, housing, cover, etc.) constituting the outer appearance of the first body 200 is formed by the first front case 220 and the first rear case 225. Various electronic components are installed in a space formed by the first front case 220 and the first rear case 225. At least one intermediate case may be additionally disposed between the first front case 220 and the first rear case 225.

The cases may be formed by injection molding of a synthetic resin or may be formed of a metal material such as stainless steel (STS) or titanium (Ti).

The display unit 151, the sound output module 152, the camera 121 or the first user input unit 210 may be disposed in the first body 200, specifically, the first front case 220.

Since the display unit 151 has already been described with reference to FIG. 1, a detailed description will be omitted for the sake of simplicity.

The sound output module 152 may be implemented in the form of a speaker.

The camera 121 may be implemented to suitably photograph an image or a moving image for a user and the like.

As in the case of the first body 200, the case constituting the outer appearance of the second body 205 is formed by the second front case 230 and the second rear case 235.

The second user input unit 215 may be disposed on the front surface of the second body 205, specifically, the second front case 230.

The third user input unit 245, the microphone 122, and the interface unit 170 may be disposed in at least one of the second front case 230 and the second rear case 235.

The first to third user input units 210, 215, and 245 may be collectively referred to as a user input unit 130 and may be employed in any manner as long as the user operates in a tactile manner with a tactile impression .

In a functional aspect, the first user input unit 210 is for inputting commands such as start, end, scrolling, etc., and the second user input unit 215 is for inputting numbers, letters, symbols and the like. The first user input unit 210 includes a so-called soft key used in conjunction with icons displayed on the display unit 151 and a navigation key (mainly composed of four direction keys and a center key) for direction indication and confirmation can do.

In addition, the third user input unit 245 may operate as a hot-key for activating a special function in the mobile terminal.

The microphone 122 may be implemented in a form suitable for receiving voice, sound, etc. of the user.

The interface unit 170 is a channel for allowing the mobile terminal 100 related to the present invention to exchange data with an external device. Since the interface unit 170 has already been described with reference to FIG. 1, a detailed description thereof will be omitted.

A power supply unit 190 for supplying power to the mobile terminal 100 is mounted on the second rear case 235 side.

The power supply unit 190 may be detachably coupled to a rechargeable battery, for example, for charging.

3 is a rear perspective view of the mobile terminal of FIG.

Referring to FIG. 3, a camera 121 may be further mounted on the rear surface of the second rear case 235 of the second body 205. The camera 121 of the second body 205 has a photographing direction which is substantially opposite to that of the camera 121 of the first body 200 and a different pixel from the camera 121 of the first body 200 Lt; / RTI >

For example, the camera 121 of the first body 200 has low pixels so that it is easy to capture a face of a user in the case of a video call or the like and transmit it to the other party, Since it is often the case that a subject is photographed and not immediately transferred, it is preferable to have a high pixel.

A flash 250 and a mirror 255 may be additionally disposed adjacent to the camera 121 of the second body 205. The flash 250 illuminates the subject when the subject of the subject is photographed by the camera 121 of the second body 205. The mirror 255 allows the user to illuminate the user's own face or the like when the user intends to take a picture of himself / herself (self-photographing) using the camera 121 of the second body 205.

The second rear case 235 may further include an acoustic output module 152.

The sound output module 152 of the second body 205 may implement a stereo function together with the sound output module 152 of the first body 200 and may be used for a call in a speakerphone mode.

In the above description, the second camera 121 and the like are disposed on the second body 205, but the present invention is not limited thereto.

For example, at least one of the configurations 260, 121 to 250, and 152 described as being disposed in the second rear case 235, such as the camera 121 of the second body, It is also possible that the first rear case 225 is mounted to the rear case 225. In such a case, there is an advantage that the configuration (s) disposed in the first rear case 225 in the closed state is protected by the second body 205. Further, even if the camera 121 of the second body is not separately provided, the camera 121 of the first body may be configured to be rotatable so that the camera 121 of the second body can be photographed up to the photographing direction .

The terminal 100 shown in Figs. 1 to 3 is operable in a communication system capable of transmitting data through a frame or a packet, including a wired / wireless communication system and a satellite-based communication system .
