Meanwhile, the sensing unit 140 senses at least one of information in the mobile terminal, surrounding environment information surrounding the mobile terminal, and user information, and generates a corresponding sensing signal. The control unit 180 may control the driving or operation of the mobile terminal 100 or may perform data processing, function or operation related to the application program installed in the mobile terminal 100 based on the sensing signal. Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen.

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. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity to the touch screen without touching the object is referred to as "proximity touch" The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor uses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, Detection.

For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. 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.

Thus, when 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. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

On the other hand, the touch sensors and the proximity sensors discussed above can be used independently or in combination to provide a short touch (touch), a long touch, a multi touch, a drag touch ), Flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, and the like. Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected 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 change of light, and position information of the object to be sensed can be obtained through the calculation.

The display unit 151 displays (outputs) information processed by the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven by the mobile terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to the execution screen information .

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

In the stereoscopic display unit, a three-dimensional display system such as a stereoscopic system (glasses system), an autostereoscopic system (no-glasses system), and a projection system (holographic system) can be applied.

Generally, 3D stereoscopic images consist of left image (left eye image) and right image (right eye image). A top-down method of arranging a left image and a right image in one frame according to a method in which a left image and a right image are combined into a three-dimensional stereoscopic image, A checker board system in which pieces of a left image and a right image are arranged in a tile form, a left-to-right (right-side) Or an interlaced method in which rows are alternately arranged, and a time sequential (frame-by-frame) method in which right and left images are alternately displayed in time.

In addition, the 3D thumbnail image may generate a left image thumbnail and a right image thumbnail from the left image and right image of the original image frame, respectively, and may be generated as one image as they are combined. 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.

2 is a conceptual diagram for explaining another example of the mobile terminal 200 according to the present invention.

As shown, the display unit 251 may be configured to be deformable by an external force. The deformation may be at least one of warping, bending, folding, twisting, and curling of the display portion 251. The deformable display portion 251 may be referred to as a " flexible display portion ". Here, the flexible display unit 251 may include both a general flexible display, e-paper, and combinations thereof. In general, mobile terminal 200 may include features of mobile terminal 100 of Figures 1A-1C or similar features.

A typical flexible display refers to a sturdy display that is lightweight and does not break easily, such as paper, formed on a thin, flexible substrate that can flex, bend, fold, twist, or curl like a conventional flat panel display.

In addition, the electronic paper is a display technology to which general ink characteristics are applied, and the point that the reflected light is used is different from the conventional flat panel display. The electronic paper can be changed by using a twist ball or electrophoresis (electrophoresis) using a capsule.

In a state in which the flexible display portion 251 is not deformed (for example, a state having an infinite radius of curvature, hereinafter referred to as a first state), the display area of the flexible display portion 251 is flat. In the first state, the display area may be a curved surface in a state deformed by an external force (for example, a state having a finite radius of curvature, hereinafter referred to as a second state). As shown in the figure, the information displayed in the second state may be time information output on the curved surface. Such visual information is realized by independently controlling the emission of a sub-pixel arranged in a matrix form. The unit pixel means a minimum unit for implementing one color.

The flexible display unit 251 may be placed in a bent state (for example, a vertical state or a left-to-right bent state) instead of a flat state in the first state. In this case, if an external force is applied to the flexible display portion 251, the flexible display portion 251 may be deformed into a flat state (or a less bent state) or a more bent state.

Meanwhile, the flexible display unit 251 may be combined with a touch sensor to implement a flexible touch screen. When a touch is made to the flexible touch screen, the control unit 180 (see FIG. 1A) can perform control corresponding to the touch input. The flexible touch screen may be configured to sense the touch input in the first state as well as the second state.

Meanwhile, the mobile terminal 200 according to the present modification may be provided with a deformation detecting means capable of detecting deformation of the flexible display unit 251. The deformation detecting means may be included in the sensing unit 140 (see FIG. 1A).

The deformation detecting unit may be provided in the flexible display unit 251 or the case 201 to sense information related to the deformation of the flexible display unit 251. Here, the information related to the deformation may be the direction in which the flexible display unit 251 is deformed, the degree of deformation, the deformation position, the deformation time, and the acceleration at which the deformed flexible display unit 251 is restored, In addition, the flexible display unit 251 may be various information that can be detected due to the bending of the flexible display unit 251.

The control unit 180 may change the information displayed on the flexible display unit 251 or change the information displayed on the flexible display unit 251 based on the information related to the deformation of the flexible display unit 251, It is possible to generate a control signal for controlling the function of the controller.

Meanwhile, the mobile terminal 200 according to the present modification may include a case 201 that accommodates the flexible display unit 251. The case 201 may be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251.

In addition, the battery (not shown) included in the mobile terminal 200 may be configured to be deformable together with the flexible display unit 251 by an external force in consideration of the characteristics of the flexible display unit 251. In order to implement the battery, a stack and folding method in which battery cells are stacked on top of one another may be applied.

The state change of the flexible display unit 251 is not limited to an external force. For example, when the flexible display unit 251 has the first state, it may be transformed to the second state by a command of the user or the application.

Meanwhile, the mobile terminal can be extended to a wearable device that can be worn on the body beyond the dimension that the user mainly grasps and uses. These wearable devices include smart watch, smart glass, and head mounted display (HMD). Hereinafter, examples of a mobile terminal extended to a wearable device will be described.

The wearable device can be made to be able to exchange (or interlock) data with another mobile terminal 100. The short range communication module 114 can detect (or recognize) a wearable device capable of communicating with the mobile terminal 100. If the detected wearable device is a device authenticated to communicate with the mobile terminal 100, the control unit 180 may transmit at least a part of the data processed by the mobile terminal 100 to the wearable device 100 via the short- Lt; / RTI > Accordingly, the user can use the data processed by the mobile terminal 100 through the wearable device. For example, when a telephone is received in the mobile terminal 100, it is possible to perform a telephone conversation via the wearable device or to confirm the received message via the wearable device when a message is received in the mobile terminal 100 .

When the display unit 351 is implemented as a touch screen, the display unit 351 may function as a user input unit 323, so that the main body 301 may not have a separate key.

The band 302 is worn on the wrist so as to surround the wrist and can be formed of a flexible material for easy wearing. As an example, the band 302 may be formed of leather, rubber, silicone, synthetic resin, or the like.

This figure illustrates that the control module 480 is provided in the frame portion on one side of the head. However, the position of the control module 480 is not limited thereto.

The display unit 451 may be implemented as a head mounted display (HMD). The HMD type refers to a display method that is mounted on a head and displays an image directly in front of the user's eyes. When the user wears the glass-type mobile terminal 400, the display unit 451 may be arranged to correspond to at least one of the left and right eyes so that the user can directly provide an image in front of the user's eyes. In this figure, the display unit 451 is located at a portion corresponding to the right eye so that an image can be output toward the user's right eye.

The display unit 451 can project an image to the user's eyes using a prism. Further, the prism may be formed to be transmissive so that the user can view the projected image and the general view of the front (the range that the user views through the eyes) together.

Next, a communication system that can be implemented through the mobile terminal 100 according to the present invention will be described.

First, the communication system may use different wireless interfaces and / or physical layers. For example, wireless interfaces that can be used by a communication system include Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA) ), Universal mobile telecommunication systems (UMTS) (in particular Long Term Evolution (LTE), Long Term Evolution-Advanced (LTE-A)), Global System for Mobile Communications May be included.

Hereinafter, for the sake of convenience of description, the description will be limited to CDMA. However, it is apparent that the present invention can be applied to all communication systems including an OFDM (Orthogonal Frequency Division Multiplexing) wireless communication system as well as a CDMA wireless communication system.

A CDMA wireless communication system includes at least one terminal 100, at least one base station (BS) (also referred to as a Node B or Evolved Node B), at least one Base Station Controllers (BSCs) , And a Mobile Switching Center (MSC). The MSC is configured to be coupled to a Public Switched Telephone Network (PSTN) and BSCs. The BSCs may be paired with the BS via a backhaul line. The backhaul line may be provided according to at least one of E1 / T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL or xDSL. Thus, a plurality of BSCs may be included in a CDMA wireless communication system.

The intersection of sector and frequency assignment may be referred to as a CDMA channel. The BS may be referred to as a base station transceiver subsystem (BTSs). In this case, a combination of one BSC and at least one BS may be referred to as a "base station ". The base station may also indicate a "cell site ". Alternatively, each of the plurality of sectors for a particular BS may be referred to as a plurality of cell sites.

A broadcast transmission unit (BT) transmits a broadcast signal to terminals 100 operating in the system. The broadcast receiving module 111 shown in FIG. 1A is provided in the terminal 100 to receive a broadcast signal transmitted by the BT.

In addition, a Global Positioning System (GPS) may be associated with the CDMA wireless communication system to identify the location of the mobile terminal 100. The satellite 300 aids in locating the mobile terminal 100. Useful location information may be obtained by two or more satellites. Here, the position of the mobile terminal 100 can be tracked using all the techniques capable of tracking the location as well as the GPS tracking technology. Also, at least one of the GPS satellites may optionally or additionally be responsible for satellite DMB transmission.

The location information module 115 included in the mobile terminal is for detecting, computing, or identifying the location of the mobile terminal, and may include a Global Position System (GPS) module and a WiFi (Wireless Fidelity) module. Optionally, the location information module 115 may perform any of the other functions of the wireless communication unit 110 to obtain data relating to the location of the mobile terminal, in addition or alternatively.

The GPS module 115 calculates distance information and accurate time information from three or more satellites and then applies trigonometry to the calculated information to accurately calculate three-dimensional current location information according to latitude, longitude, and altitude can do. 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 115 can calculate speed information by continuously calculating the current position in real time. However, it is difficult to accurately measure the position of the mobile terminal by using the GPS module in the shadow area of the satellite signal as in the room. Accordingly, a WPS (WiFi Positioning System) can be utilized to compensate the positioning of the GPS system.

The WiFi Positioning System (WPS) is a system in which a mobile terminal 100 uses a WiFi module included in the mobile terminal 100 and a wireless AP (wireless access point) transmitting or receiving a wireless signal with the WiFi module, Is a technology for tracking a location of a wireless local area network (WLAN) using WiFi.

The WiFi location tracking system may include a Wi-Fi location server, a mobile terminal 100, a wireless AP connected to the mobile terminal 100, and a database in which certain wireless AP information is stored.

The mobile terminal 100 connected to the wireless AP can transmit a location information request message to the Wi-Fi location server.

The Wi-Fi position location server extracts information of the wireless AP connected to the mobile terminal 100 based on the location information request message (or signal) of the mobile terminal 100. The information of the wireless AP connected to the mobile terminal 100 may be transmitted to the Wi-Fi location server through the mobile terminal 100 or may be transmitted from the wireless AP to the Wi-Fi location server.

The information of the wireless AP to be extracted based on the location information request message of the mobile terminal 100 includes a MAC address, an SSID (Service Set IDentification), a Received Signal Strength Indicator (RSSI), a Reference Signal Received Power (RSRP) Reference Signal Received Quality), channel information, Privacy, Network Type, Signal Strength, and Noise Strength.

As described above, the Wi-Fi position location server can receive the information of the wireless AP connected to the mobile terminal 100 and extract the wireless AP information corresponding to the wireless AP to which the mobile terminal is connected from the pre-established database. In this case, the information of any wireless APs stored in the database includes at least one of MAC address, SSID, channel information, privacy, network type, radius coordinates of the wireless AP, building name, Available), the address of the AP owner, telephone number, and the like. At this time, in order to remove the wireless AP provided using the mobile AP or the illegal MAC address in the positioning process, the Wi-Fi location server may extract only a predetermined number of wireless AP information in order of RSSI.

Then, the Wi-Fi location server can extract (or analyze) the location information of the mobile terminal 100 using at least one wireless AP information extracted from the database. And compares the received information with the received wireless AP information to extract (or analyze) the location information of the mobile terminal 100.

As a method for extracting (or analyzing) the position information of the mobile terminal 100, a Cell-ID method, a fingerprint method, a triangulation method, and a landmark method can be utilized.

The Cell-ID method is a method of determining the position of the mobile station with the strongest signal strength among neighboring wireless AP information collected by the mobile terminal. Although the implementation is simple, it does not cost extra and it can acquire location information quickly, but there is a disadvantage that positioning accuracy is lowered when the installation density of the wireless AP is low.

The fingerprint method collects signal strength information by selecting a reference position in a service area, and estimates the position based on the signal strength information transmitted from the mobile terminal based on the collected information. In order to use the fingerprint method, it is necessary to previously convert the propagation characteristics into a database.

The triangulation method is a method of calculating the position of the mobile terminal based on the coordinates of at least three wireless APs and the distance between the mobile terminals. (Time of Arrival, ToA), Time Difference of Arrival (TDoA) in which a signal is transmitted, and the time difference between the wireless AP and the wireless AP, in order to measure the distance between the mobile terminal and the wireless AP. , An angle at which a signal is transmitted (Angle of Arrival, AoA), or the like.

The landmark method is a method of measuring the position of a mobile terminal using a landmark transmitter that knows the location.

Various algorithms can be utilized as a method for extracting (or analyzing) the location information of the mobile terminal.

The extracted location information of the mobile terminal 100 is transmitted to the mobile terminal 100 through the Wi-Fi location server, so that the mobile terminal 100 can acquire the location information.

The mobile terminal 100 may be connected to at least one wireless AP to obtain location information. At this time, the number of wireless APs required to acquire the location information of the mobile terminal 100 may be variously changed according to the wireless communication environment in which the mobile terminal 100 is located.

As shown in FIG. 1A, a mobile terminal according to the present invention includes Bluetooth ™, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, NFC Field Communication), and Wireless USB (Wireless Universal Serial Bus).

Among them, the NFC module provided in the mobile terminal supports the non-contact type short-range wireless communication between the terminals at a distance of about 10 cm. The NFC module may operate in either a card mode, a reader mode, or a P2P mode. In order for the NFC module to operate in the card mode, the mobile terminal 100 may further include a security module for storing card information. Here, the security module may be a physical medium such as a UICC (e.g., a SIM (Subscriber Identification Module) or a USIM (Universal SIM)), a Secure micro SD and a sticker, or a logical medium For example, embeded SE (Secure Element)). Data exchange based on SWP (Single Wire Protocol) can be made between NFC module and security module.

When the NFC module is operated in the card mode, the mobile terminal can transmit the stored card information to the outside such as a conventional IC card. Specifically, if the mobile terminal storing the card information of the payment card such as a credit card or a bus card is brought close to the fare payment machine, the mobile local payment can be processed, and the mobile terminal storing the card information of the access card can be accessed If you are close to the time, the approval process for access may begin. Cards such as credit cards, transportation cards, and access cards are mounted on the security module in the form of an applet, and the security module can store card information on the mounted card. Here, the card information of the payment card may be at least one of a card number, balance, and usage details, and the card information of the access card may include at least one of a name, a number (e.g., It can be one.

When the NFC module is operated in the reader mode, the mobile terminal can read data from an external tag. At this time, the data received from the mobile terminal by the tag may be coded into a data exchange format (NFC Data Exchange Format) defined by the NFC Forum. In addition, the NFC Forum defines four record types. Specifically, the NFC forum defines four RTDs (Record Type Definitions) such as Smart Poster, Text, Uniform Resource Identifier (URI), and General Control. If the data received from the tag is a smart poster type, the control unit executes a browser (e.g., an Internet browser), and if the data received from the tag is a text type, the control unit can execute the text viewer. When the data received from the tag is a URI type, the control unit executes the browser or makes a telephone call, and if the data received from the tag is a general control type, it can execute appropriate operations according to the control contents.

When the NFC module is operated in a peer-to-peer (P2P) mode, the mobile terminal can perform P2P communication with another mobile terminal. At this time, LLCP (Logical Link Control Protocol) may be applied to P2P communication. For P2P communication, a connection can be created between the mobile terminal and another mobile terminal. At this time, the generated connection can be divided into a connectionless mode in which one packet is exchanged and terminated, and a connection-oriented mode in which packets are exchanged consecutively. Through P2P communications, data such as business cards, contact information, digital photos, URLs in electronic form, and setup parameters for Bluetooth and Wi-Fi connectivity can be exchanged. However, since the usable distance of NFC communication is short, the P2P mode can be effectively used to exchange small-sized data.
