The components shown in Fig. 1 are not essential, so that a mobile terminal having more or fewer components can be implemented.

Hereinafter, the components 110 to 190 of the mobile terminal 100 will be described in order.

The wireless communication unit 110 may include one or more modules for enabling wireless communication between the mobile terminal 100 and the wireless communication system or 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 distance communication module 114, and a location information module 115.

The broadcast receiving module 111 receives broadcast signals and broadcast related information from an external broadcast management server through a broadcast channel. Here, the broadcast-related information means information related to a broadcast channel, a broadcast program, or a broadcast service provider. The broadcast-related information can also be provided through a mobile communication network. In this case, the broadcast-related information may be received by the mobile communication module 112. The broadcast signal and the broadcast related information received through the broadcast receiving module 111 may be stored in the memory 160.

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. Such wireless signals may include various types of data depending on a voice call signal, a video call signal, a text message, or a multimedia message transmission / reception.

The wireless Internet module 113 is a module for wireless Internet access, and may be embedded in the mobile terminal 100 or externally. Wireless Internet technologies may include Wireless LAN (Wi-Fi), Wireless Broadband (Wibro), World Interoperability for Microwave Access (Wimax), High Speed Downlink Packet Access (HSDPA), and the like.

The short range communication module 114 refers to a module for short range communication. As a short range communication technology, Bluetooth, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, and the like can be used.

The position information module 115 is a module for acquiring the position of the mobile terminal 100, and a representative example thereof is a Global Position System (GPS) module.

1, an A / V (Audio / Video) input unit 120 is for inputting an audio signal and a video signal, and may include a camera 121, a microphone 122, and the like. The camera 121 processes image frames such as still images and moving images obtained by the image sensor in the video communication mode or the photographing mode. The image frame processed by the camera 121 can be displayed on the display unit 151. [ The image frame may be stored in the memory 160 or transmitted to the outside through the wireless communication unit 110. [ More than two cameras 121 may be provided depending on the use environment.

The microphone 122 processes the sound signal input from the outside in the communication mode, the recording mode, the voice selection mode, and the like as electrical voice data. The voice data processed by the microphone 122 in the communication mode can be converted into a form that can be transmitted to the mobile communication base station through the mobile communication module 112 and output. The microphone 122 may be implemented with various noise reduction algorithms for eliminating noise generated when an external sound signal is input.

The user input unit 130 generates input data for controlling the operation of the mobile terminal 100 by a user. The user input unit 130 may include a key pad, a dome switch, a touch pad (static pressure and static electricity), a jog wheel, a jog switch, and the like.

The sensing unit 140 senses the current state of the mobile terminal 100 such as presence or absence of a user, the open / close state of the mobile terminal 100, position, orientation, acceleration, deceleration, And generates a sensing signal. For example, when the mobile terminal 100 is in the form of a slide phone, the sensing unit 140 may detect whether the slide phone is opened or closed. The sensing unit 140 may sense whether the power supply unit 190 is powered on, whether the interface unit 170 is connected to an external device, and the like.

The detector 140 may include a proximity sensor 141, a stereoscopic touch detector 142, an ultrasonic detector 143, and a camera detector 144. The sensing unit 140 may also be configured as a three-dimensional sensor that detects the position of a moving object (hereinafter, referred to as a “detecting object”) existing in a three-dimensional space. Here, the sensing object may be, for example, a body part (finger) of the user, an accessory device, or the like.

The sensing unit 140 may include a touch sensor (not shown) for sensing a touch operation with respect to the display unit 151. The touch sensor may have the form of a touch film, a touch sheet, a touch pad, or the like. The touch sensor may be configured to convert a pressure applied to a specific portion of the display portion 151 or a change in capacitance generated at a specific portion of the display portion 151 into an electrical input signal. The touch sensor may be configured to detect a touch pressure as well as a touched position and area.

When the touch sensor and the display unit 151 have a mutual layer structure, the display unit 151 can be used as an input device in addition to the output device. The display unit 151 may be referred to as a touch screen.

If there is a touch input via the touch screen, signals corresponding thereto are sent to a touch controller (not shown). The touch controller processes the signals transmitted from the touch sensor, and then transmits data corresponding to the processed signals to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched.

In the case where the touch screen is electrostatic, it can be configured to detect the proximity of the sensing object by a change of the electric field along the proximity of the sensing target. Such a touch screen may be classified as proximity sensor 141. [

The proximity sensor 141 refers to a sensor that detects the presence or absence of an object to be sensed without mechanical contact using an electromagnetic force or infrared rays. 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.

The proximity sensor 141 may be displayed in the inner region of the mobile terminal 100 surrounded by the touch screen or near the touch screen. The proximity sensor 141 measures the distance between a sensing object (for example, a user's finger or a stylus pen) to which a touch is applied without a mechanical contact by using an electromagnetic force or infrared rays, and a detection surface. The proximity sensor 141 may recognize which part of the stereoscopic image is touched using the measured distance.

Meanwhile, the proximity sensor 141 may be configured to detect a touch on a three-dimensional space by using the proximity of the sensing object.

The output unit 150 generates an output related to visual, auditory, tactile, and the like. The output unit 150 may include a display unit 151, an audio output module 152, an alarm unit 153, and a haptic module 154.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, when the mobile terminal 100 operates in the call mode, the display unit 151 displays a UI (User Interface) or a GUI (Graphic User Interface) related to the call. When the mobile terminal 100 operates in the video communication mode or the photographing mode, the display unit 151 displays the photographed image, the received image, the UI, the GUI, and the like.

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.

At least one display (or display element) included in the display unit 151 may be configured to be transparent or light transmissive so that the display can see the outside through it. This can be referred to as a transparent display. A typical example of such a transparent display is TOLED (Transparent OLED). The rear structure of the display unit 151 may also be of a light transmission type. With this structure, the user can see an object located behind the terminal body through the area occupied by the display unit 151 in 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 each other or positioned integrally with one another, and may be located on different surfaces.

The display unit 151 may be configured as a stereoscopic display unit for displaying a stereoscopic image. Here, the stereoscopic image represents a three-dimensional stereoscopic image, and the three-dimensional stereoscopic image represents a gradual depth and reality in which an object is placed on a monitor or a screen. It is a video that makes you feel the same as the real space.

3D stereoscopic images are implemented using binocular disparity. Here, binocular parallax means a parallax formed by positions of two eyes about 65 millimeters apart, and when two eyes see different two-dimensional images and the images are transmitted to the brain through the retina and merged, the depth of the stereoscopic image is sensed. And you can feel the reality.

In the present specification, the term “depth value” refers to an index indicating a distance difference between objects included in a 3D image. More specifically, when the object displayed by the display unit 151 is shown to the user in a two-dimensional form, the depth value of the object may be defined as "0". However, a depth value of an object that appears to protrude out of the mobile terminal 100 based on the screen of the display unit 151 in a three-dimensional form may be defined as a negative number. On the other hand, the depth value of the object that appears to enter the inside of the mobile terminal 100 may be defined as a positive number. In addition, as the position of the object included in the 3D image of the protruding shape is near, the absolute value of the depth value of the object increases, and the position of the object included in the 3D image of the shape that has been entered is far. The more the depth value of the object increases.

Hereinafter, for convenience of description, the position where the object included in the 3D image is seen is expressed as 'the depth value of the object is larger' as the short distance and 'depth value of the object is smaller' as the distance is longer.

The stereoscopic display unit may be a three-dimensional display method such as a stereoscopic method (glasses method), an auto stereoscopic method (glasses-free method), a projection method (holographic method). The stereoscopic method, which is widely used in home television receivers, includes a Wheatstone stereoscopic method.

Examples of the auto stereoscopic method include a parallax barrier method, a lenticular method, an integrated imaging method, and the like. The projection method includes a reflection type holographic method and a transmission type holographic method.

Generally, a 3D stereoscopic image is composed of a left image (left eye image) and a right image (right eye image). The 3D stereoscopic image may be implemented by a top-down method of displaying a left image and a right image up and down in one frame according to a method in which a left image and a right image are combined into a 3D stereoscopic image. Left-to-right, side by side (L-to-R) method that displays left and right images left and right in one frame, and checker board that displays pieces of left and right images in tile form The method is divided into an interlaced method of alternately displaying a left image and a right image in a column unit or a row unit, and a time sequential (frame by frame) method of alternately displaying a left image and a right image by time.

As an example of a 3D stereoscopic image, a 3D thumbnail image may generate a left image thumbnail and a right image thumbnail from a left image and a right image of an original image frame, respectively, and combine them to generate a single 3D thumbnail image. have. In general, a thumbnail refers to a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated as described above are displayed at a depth corresponding to the parallax of the left image and the right image at a left and right distance difference, thereby representing a three-dimensional space.

When the stereoscopic display unit and the touch sensor form a mutual layer structure, or when the stereoscopic display unit and the 3D sensor for detecting the touch operation are combined with each other, the stereoscopic display unit may be used as a 3D input device. Such a stereoscopic display may be referred to as a “stereoscopic touch screen”.

The sound output module 152 may output audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception, a call mode or a recording mode, a voice selection mode, a broadcast reception mode, and the like. The sound output module 152 may also output a sound signal related to a function (eg, a call signal reception sound, a message reception sound, etc.) performed in the mobile terminal 100. The sound output module 152 may include a receiver, 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 generated in the mobile terminal 100 include call signal reception, message reception, key signal input, touch input, and the like. The alarm unit 153 may output a signal for notifying occurrence of an event by vibration, in addition to a video signal or an audio signal. Since the video signal or the audio signal may also be output through the display unit 151 or the audio output module 152, the display unit 151 and the audio output module 152 may be classified as part of the alarm unit 153.

The haptic module 154 generates various tactile effects that the user can feel. Vibration is a representative example of the haptic effect generated by the haptic module 154. The intensity, pattern, and the like of the vibration generated by the haptic module 154 can be controlled. For example, different vibrations may be synthesized and output or sequentially output.

In addition to vibration, the haptic module 154 may be configured to provide a pin array that vertically moves with respect to the contact skin surface, a jetting force or suction force of air through the jetting or suction port, grazing to the skin surface, contact of the electrode, electrostatic force, and the like. Various tactile effects can be generated, such as effects due to endothermic or reproducing a sense of cold using a heat generating element.

The haptic module 154 may not only deliver a haptic effect through direct contact, but may also be configured to allow the user to feel the haptic effect through a muscle sense such as a finger or an arm. At least two haptic modules 154 may be provided according to the configuration of the mobile terminal 100.

The memory 160 may store a program for the operation of the controller 180 and temporarily store input and output data (e.g., a phone book, a message, a still image, a moving picture, etc.). The memory 160 may store data related to vibrations and sounds of various patterns that are output upon touch input on the touch screen.
