The A/V input unit 120 may receive an audio or video signal. The A/V input unit 120 may include a camera 121 (or other image capture device) and a microphone 122 (or other sound pick-up device). The camera 121 may process image data of still pictures or video obtained by an image capture device in a video capturing mode or an image capturing mode. The processed image frames may be displayed on a display 151 (or other visual output device). The display 151 may also be considered a display module or display unit.
The image frames processed by the camera 121 may be stored in the memory 160 (or other storage medium) or may be transmitted via the wireless communication unit 110. Two or more cameras 121 may be provided according to the configuration of the mobile terminal 100.
The microphone 122 may receive sounds (audible data) via a microphone (or the like) in a phone call mode, a recording mode, a voice recognition mode, and/or the like, and the microphone 122 can process such sounds into audio data. The processed audio (voice) data may be converted for output into a format transmittable to a mobile communication base station (or other network entity) via the mobile communication module 112 in case of the phone call mode. The microphone 122 may implement various types of noise removing (or suppression) algorithms to remove (or suppress) noise or interference generated in the course of receiving and transmitting audio signals.
The user input unit 130 (or other user input device) may generate input data from commands entered by a user to control various operations of the mobile terminal 100. The user input unit 130 may include a keypad, a dome switch, a touch pad (e.g., a touch sensitive member that detects changes in resistance, pressure, capacitance, etc. due to being contacted), a jog wheel, a jog switch, and/or the like.
The sensing unit 140 (or other detection means) may detect a current status (or state) of the mobile terminal 100 such as an opened state or a closed state of the mobile terminal 100, a location of the mobile terminal 100, presence or absence of user contact with the mobile terminal 100 (i.e., touch inputs), orientation of the mobile terminal 100, an acceleration or deceleration movement and direction of the mobile terminal 100, etc., and the sensing unit 140 may generate commands or signals for controlling an operation of the mobile terminal 100. For example, when the mobile terminal 100 is implemented as a slide type mobile phone, the sensing unit 140 may sense whether the slide phone is opened or closed. Additionally, the sensing unit 140 may detect whether or not the power supply unit 190 supplies power or whether or not the interface unit 170 is coupled with an external device. The sensing unit 140 may include a proximity sensor 141.
The output unit 150 may provide outputs in a visual, audible, and/or tactile manner (e.g., audio signal, video signal, alarm signal, vibration signal, etc.). The output unit 150 may include the display 151, an audio output module 152, an alarm 153, a haptic module 154, and/or the like.
The display 151 may display (output) information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display 151 may display a User Interface (UI) or a Graphic User Interface (GUI) associated with a call or other communication (such as text messaging, multimedia file downloading, etc.). When the mobile terminal 100 is in a video call mode or an image capturing mode, the display 151 may display a captured image and/or a received image, a UI or a GUI that shows videos or images and functions related thereto, and the like.
The display 151 may include at least one of a Liquid Crystal Display (LCD), a Thin Film Transistor-LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, a three-dimensional (3D) display, and/or the like.
The display 151 may be configured to be transparent or light-transmissive to allow viewing of an exterior, which may be called a transparent display. A transparent display may be a TOLED (Transparent Organic Light Emitting Diode) display, and/or the like, for example. Through such configuration, the user can view an object positioned at the rear side of the terminal body through a region occupied by the display 151 of the terminal body.
The mobile terminal 100 may include two or more display units (or other display means) according to a particular desired embodiment. For example, a plurality of displays (or display units) may be separately or integrally disposed on one surface of the mobile terminal 100, or the plurality of displays may be separately disposed on mutually different surfaces.
When the display 151 and a sensor (hereinafter referred to as a touch sensor) for detecting a touch operation are overlaid in a layered manner to form a touch screen, the display 151 may function as both an input device and an output device. The touch sensor may have a form of a touch film, a touch sheet, a touch pad, and/or the like.
The touch sensor may convert pressure applied to a particular portion of the display 151 or a change in capacitance or the like generated at a particular portion of the display 151 into an electrical input signal. The touch sensor may be configured to detect the pressure when a touch is applied, as well as the touched position and area.
When there is a touch input with respect to the touch sensor, a corresponding signal (signals) may be transmitted to a touch controller. The touch controller may process the signals and transmit corresponding data to the controller 180. Accordingly, the controller 180 may recognize which portion of the display 151 has been touched.
With reference to FIG. 1, a proximity sensor 141 may be disposed within or near the touch screen. The proximity sensor 141 may be a sensor for detecting presence or absence of an object relative to a certain detection surface or an object that exists nearby by using the force of electromagnetism or infrared rays without a physical contact. Thus, the proximity sensor 141 may have a considerably longer life span compared with a contact type sensor, and the proximity sensor 141 can be utilized for various purposes.
Examples of the proximity sensor 141 may include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror-reflection type photoelectric sensor, an RF oscillation type proximity sensor, a capacitance type proximity sensor, a magnetic proximity sensor, an infrared proximity sensor, and/or the like. In an example where the touch screen is the capacitance type, proximity of the pointer may be detected by a change in electric field according to proximity of the pointer. In this example, the touch screen (touch sensor) may be classified as a proximity sensor.
In the following description, for the sake of brevity, recognition of the pointer positioned to be close to the touch screen may be called a ‘proximity touch’, while recognition of actual contacting of the pointer on the touch screen may be called a ‘contact touch’. In this example, when the pointer is in the state of the proximity touch, it means that the pointer is positioned to correspond vertically to the touch screen.
By employing the proximity sensor 141, a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch speed, a proximity touch time, a proximity touch position, a proximity touch movement state, and/or the like) may be detected, and information corresponding to the detected proximity touch operation and the proximity touch pattern may be outputted to the touch screen.
The audio output module 152 may convert and output (as sound audio) data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and/or the like. The audio output module 152 may provide audible outputs related to a particular function performed by the mobile terminal 100 (e.g., a call signal reception sound, a message reception sound, etc.). The audio output module 152 may include a speaker, a buzzer, and/or other sound generating device.
The alarm 153 (or other type of user notification means) may provide outputs to inform about occurrence of an event of the mobile terminal 100. Events may include call reception, message reception, key signal inputs, a touch input etc. In addition to audio or video outputs, the alarm 153 may provide outputs in a different manner to inform about an occurrence of an event. For example, the alarm 153 may provide an output in the form of vibrations (or other tactile or sensible outputs). When a call, a message, and/or some other incoming communication is received, the alarm 153 may provide tactile outputs (i.e., vibrations) to inform the user thereof. By providing such tactile outputs, the user may recognize the occurrence of various events even if the mobile terminal is in the user's pocket. Outputs informing about the occurrence of an event may be also provided via the display 151 or the audio output module 152. The display 151 and the audio output module 152 may be classified as a part of the alarm 153.
The haptic module 154 may generate various tactile effects that the user may feel. Vibration may be one example of the tactile effects generated by the haptic module 154. A strength and a pattern of the haptic module 154 may be controlled. For example, different vibrations may be combined to be outputted or sequentially outputted.
Besides vibration, the haptic module 154 may generate various other tactile effects such as an effect by stimulation such as a pin arrangement vertically moving with respect to a contact skin, a spray force or a suction force of air through a jet orifice or a suction opening, a contact on the skin, a contact of an electrode, electrostatic force, etc., an effect by reproducing a sense of cold and warmth using an element that can absorb or generate heat.
The haptic module 154 may be implemented to allow the user to feel a tactile effect through a muscle sensation such as fingers or arm of the user, as well as transferring the tactile effect through a direct contact. Two or more haptic modules 154 may be provided according to configuration of the mobile terminal 100.
The memory 160 may store software programs used for processing and controlling operations performed by the controller 180, or the memory 160 may temporarily store data (e.g., a phonebook, messages, still images, video, etc.) that are inputted or outputted. The memory 160 may also store data regarding various patterns of vibrations and audio signals outputted when a touch is inputted to the touch screen.
The memory 160 may include at least one type of storage medium such as a Flash memory, a hard disk, a multimedia card micro type, a card-type memory (e.g., SD or DX memory, etc), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a Read-Only Memory (ROM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), a Programmable Read-Only memory (PROM), a magnetic memory, a magnetic disk, and/or an optical disk. The mobile terminal 100 may operate in relation to a web storage device that performs the storage function of the memory 160 over the Internet.
The interface unit 170 may serve as an interface with every external device connected with the mobile terminal 100. For example, the external devices may transmit data to an external device, receive and transmit power to each element of the mobile terminal 100, and/or transmit internal data of the mobile terminal 100 to an external device. For example, the interface unit 170 may include wired or wireless headset ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, and/or the like.

The device having the identification module (hereinafter also referred to as an identifying device) may be in the form of a smart card. Accordingly, the identifying device may be connected to the mobile terminal 100 via a port.
When the mobile terminal 100 is connected with an external cradle, the interface unit 170 may serve as a passage to allow power from the cradle to be supplied therethrough to the mobile terminal 100, or the interface unit 170 may serve as a passage to allow various command signals inputted by the user from the cradle to be transferred to the mobile terminal 100 therethrough. Various command signals or power inputted from the cradle may operate as signals for recognizing that the mobile terminal 100 is properly mounted on the cradle.
The controller 180 may control general operations of the mobile terminal 100. For example, the controller 180 may perform controlling and processing associated with voice calls, data communications, video calls, and/or the like. The controller 180 may include a multimedia module 181 for reproducing multimedia data. The multimedia module 181 may be configured within the controller 180 or may be configured to be separated from the controller 180.
The controller 180 may perform a pattern recognition process to recognize a handwriting input or a picture drawing input performed on the touch screen as characters or images, respectively.
The power supply unit 190 may receive external power or internal power and may supply appropriate power required for operating respective elements and components under the control of the controller 180.

The antenna coil 211 may be a portion of an electromagnetic induction type communication system that reads information upon transmitting and receiving magnetic flux to and from an antenna of a reader that forms an antenna of a radio-frequency identification (RFID) tag. However, embodiments are not limited thereto. For example, the antenna coil 211 may transmit and receive a radio signal to and from an antenna coil of a different terminal.
An integrated circuit (IC) of the RFID tag may be provided on the circuit board 281. In order to electrically connect the integrated circuit and the antenna coil 211, the antenna coil 211 may extend to an auxiliary circuit board 283, and the auxiliary circuit board 283 may be electrically connected to the circuit board 281. A rear camera may also be provided (or mounted) on the auxiliary circuit board 283.
The antenna device 210 may be a passive type antenna device, a semi-passive type antenna device, and/or an active type antenna device according to power using RFID. In an example of the passive type antenna device, the mobile terminal may read information of the IC by using a change in magnetic flux at the reader, as energy. In the semi-passive type antenna device, power of the battery 241 may be used to read information of the IC. In the active type antenna device, power of the battery 241 may be used to read information of the IC and transmit and receive the information.
As shown in FIGS. 3 and 5, a change in the magnetic flux generated when the antenna coil 211 comes close to the reader may be interfered by a conductor installed in the terminal body. The conductor may be a battery, a speaker, a camera, a vibration motor, and/or the like, for example.
The ferrite sheet 212 may restrain interference to the change in magnetic flux generated by the conductor. The ferrite sheet 212 may remove noise with respect to reception of the change in magnetic flux. The ferrite sheet 212 may be provided (or disposed) on the battery 241 such that a distance is formed between the ferrite sheet 212 and the antenna coil 211.
The ferrite sheet 212 may have a structure in which various metal compounds (assuming magnetism) have a form of paper that may be attached to the surface of the battery 241. The ferrite sheet 212 may be spaced apart from the antenna coil 211, and/or the ferrite sheet 212 may be disposed at a position adjacent to the antenna coil 211 so the antenna device 210 may be configured such that the ferrite sheet 212 and the antenna coil 211 are separated.
The antenna coil 211 may be wound around the structure (i.e., case, frame or the like) of the mobile terminal 200, and the ferrite sheet 212 may be attached to an electronic element (i.e., battery or the like) adjacent thereto, so the ferrite sheet 212 and the antenna coil 211 may be separately disposed.
The battery 241 may include a front surface, a rear surface, and a side surface. The ferrite sheet 212 may include a first ferrite sheet 212a provided (or mounted) on a side surface of the battery 241 to face the side wall portion 242a (of the accommodation portion 242). The first ferrite sheet 212a may cover respective side surfaces corresponding to four sides of the battery 241.
The antenna coil 211 may be wound around an outer circumferential surface of the side wall portion 242a such that a distance between the ferrite sheet 212a and the antenna coil 211 may be formed by a thickness of the side wall portion 242a. A strong magnetic field may be uniformly generated by the first ferrite sheet 212a that faces the antenna coil 211 in a width direction of the mobile terminal, and an effect of lengthening a communication distance to the reader may be obtained according to experimentation.
The ferrite sheet 212 may include a second ferrite sheet 212b provided (or mounted) on at least one of a front surface and/or a rear surface of the battery 241.
The second ferrite sheet 212b may face a same direction as that of the rear surface of the terminal body in a state in which the connection terminal 241a (of the battery 241) and the coupling terminal 243 (of the accommodation portion 242) are electrically connected. The second ferrite sheet 212b may be provided on a surface that faces the outside when the battery 241 is accommodated in the accommodation portion 242.
The second ferrite sheet 212b may form a label of the battery 241. For example, a label that includes various types of information of the battery 241 written thereon may be attached on a surface that faces the outside, and the label may be the second ferrite sheet 212b. The first and second ferrite sheets 212a and 212b may be integrally formed. For example, the ferrite sheet 212 may be implemented by mounting a single sheet on the battery 241.
Features described in the present embodiment may maximize area and space of the ferrite sheet 212 to re-form a magnetic field such that the magnetic field is strong and uniformly distributed.

The accommodation portion 342 may include a side wall portion 342a and a bottom portion 342b. 
For example, a battery 341 may be provided such that at least a portion of the battery 341 protrudes more than the rear surface of the rear case 302, in a state in which the battery 341 is provided in the accommodation portion 342. The peripheral protrusion 344 may be sufficiently high to cover a protruded portion of the battery 341. The antenna coil 311 may be combined with a ferrite sheet 312 provided (or mounted) on the battery 341 within the accommodation portion 342 to implement near field communication. The antenna coil 311 may be positioned to be as close as possible to an outside of the mobile terminal. The ferrite sheet 312 may include a first ferrite sheet 312a and a second ferrite sheet 312b. 
FIG. 6 also shows a circuit board 381, a shield member 382, a coupling terminal 343, a front case 301, a battery cover 303 and a connection terminal 341a. 
FIG. 7 shows an accommodation portion 442 having a bottom portion 442b and a side wall portion 442a. The bottom portion 442b may be configured as a portion of a rear case. A stop protrusion 445 may be formed on an outer circumferential surface of the side wall portion 442a such that an antenna coil 411 is caught thereby. The stop protrusion 445 may be provided from the outer circumferential surface of the side wall portion 442a. A plurality of stop protrusions may allow a plurality of strands of the antenna coil 411 to be caught thereby, respectively.
When the antenna coil 411 has a form of a wire, the wire may be easily wound and may be caught by the stop protrusion 445. After the wire is wound, the antenna coil 411 may be restrained from moving on the outer circumferential surface of the side wall portion 442a. 
In the FIG. 7 embodiment, the stop protrusion 445 may protrude from the outer circumferential surface of the side wall portion 442a, although embodiments are not necessarily limited thereto. For example, the stop protrusion 445 may be compressed to the outer circumferential surface of the side wall portion 442a through heat fusion.
FIG. 7 also shows a ferrite sheet 412 and a battery 441.
FIG. 8 shows an accommodation portion 542 having a side wall portion 542a and a bottom wall portion 542b. An accommodation recess 546 that accommodates at least a portion of an antenna coil 511 may be formed on an outer circumferential surface of the side wall portion 542a. The antenna coil 511 may fill an interior of the accommodation recess 546. The antenna coil 511 may be patterned along the accommodation recess 546 through plating or deposition. FIG. 8 also shows a ferrite sheet 512.

The frame structure 604 may be mounted on a front case 601 or a rear case 602, or the frame structure 604 may be integrally formed with the front case 601 or the rear case 602. A battery 641 may be a fixed type battery in at least one embodiment.
FIG. 9 also shows a circuit board 681.
An antenna coil 611 may be wound around the frame structure 604. The battery 641 may be accommodated within the frame structure 604. A ferrite sheet 612 may be formed by coating a metal compound (assuming magnetism) on a structure of the battery 641 (i.e., an external frame of the battery 641) or by inserting the metal compound within the structure. According to the structure, a thickness of the terminal may be reduced.
In the above-described mobile terminal, since the ferrite sheet 612 is formed on the battery 641, an influence of the battery 641 may be minimized (or reduced) to thus enhance performance of near field communication. With such a structure, an area and a space of the ferrite sheet 612 may be maximized (or increased) to form a magnetic field that is strong and evenly distributed.
Additionally, since the antenna coil 611 is wound around an accommodation portion 641 and the ferrite sheet 612 is spaced apart from the antenna coil 611, the mobile terminal may perform near field communication although it has a slimmer design.
A configuration in which the antenna coil 611 is wound along edges of the structure mounted in the main body and the ferrite sheet 612 is disposed on one surface of an electronic element disposed to be adjacent to the structure may be implemented in a different manner. An embodiment implemented in a different manner may be described.

With reference to FIG. 10, a window 1251b may be coupled to one surface of a front case 1201. The window 1251b may be made of a material that allows light to be transmitted therethrough. For example, the window 1251b may be made of a light-transmissive synthetic resin, tempered glass, and/or the like. The window 1251b may include a portion that does not allow light to be transmitted therethrough. The portion through which light is not transmitted may be implemented by covering the window 1251b with a pattern film (not shown). The pattern film may be configured such that a central portion thereof is transparent and edges thereof are opaque. The window 1251b may be divided (or separated) into an edge region S that is opaque and a central region M that is surrounded by the edge region S.

The portion of the window 1251b through which light is transmitted may have an area that corresponds to the display 1251a. Accordingly, a user may recognize visual information output to the display 1251a from outside. The window 1251b and the display 1251a may constitute a display unit (i.e., the display unit 251 in FIG. 2A).
A circuit board 1281 may be mounted on a rear case 1202. Alternatively, the circuit board 1281 may be provided (or mounted) on the front case 1201, or the circuit board 1281 may be provided (or mounted) on an internal structure.

A touch sensor 1260 may be provided (or mounted) on the window 1251b to sense a touch input. The touch sensor 1260 may be formed to correspond to the window 1251b. The touch sensor 1260 may be formed to sense a touched point with respect to the window 1251b. 
The touch sensor 1260 may be light-transmissive, and the touch sensor 1260 may be configured to convert a change in voltage, capacitance, and/or the like, into an electrical input signal. For example, the touch sensor 1260 may be a capacitive sensor.
An antenna device 1210 to perform short-range communication may be provided within the mobile terminal. The circuit board 1281 may be electrically connected to the antenna device 1210. The circuit board 1281 may process a radio signal that is transmitted and received by the antenna device 1210.

As shown in FIGS. 10 and 11, the antenna coil 1211 may be wound along edges of the window 1251b to transmit and/or receive a radio signal in relation to near field communication. The antenna coil 1211 may be formed on a rear surface of the window 1251b at the edge region S (of the window 1251b) to receive a change in magnetic flux generated in a vicinity of the front surface of the mobile terminal. The antenna coil 1211 may be patterned on the rear surface of the window 1251b through plating, deposition, fine wiring bonding, and/or the like.
However, embodiments are not necessarily limited thereto. The antenna coil 1211 may be wound on a side of the window 1251b. 
The antenna coil 1211 may be a portion of an electromagnetic induction type communication system that transmits and receives magnetic flux to and from an antenna of a reader to read information. The antenna coil 1211 may form an antenna of a radio-frequency identification (RFID) tag. However, embodiments are not limited thereto. The antenna coil 1211 may transmit and receive a radio signal to and from a different terminal.

In order to electrically connect the integrated circuit and the antenna coil 1211, the antenna coil 1211 may extend to a flexible circuit board 1283.

The antenna device 1210 may be a passive type antenna device, a semi-passive type antenna device, and/or an active type antenna device based on power for using RFID. In the passive type antenna device, the mobile terminal may read information of the IC by using a change in magnetic flux at the reader, as energy. In the semi-passive type antenna device, power of the mobile terminal may be used to read information of the IC. In the active type antenna device, power of the mobile terminal may be used to read the information of the IC and transmit and receive the information.
A change in the magnetic flux generated when the antenna coil 1211 comes close to the reader may be interfered by a conductor provided in the mobile terminal body. The conductor may be the display 1251a, the touch sensor 1260, a battery, a speaker, a camera, a vibration motor, and/or the like, for example.
The ferrite sheet 1212 may restrain interference to the change in magnetic flux generated by the conductor. The ferrite sheet 1212 may remove noise with respect to a radio signal that is transmitted and received. The ferrite sheet 1212 may be disposed on the display 1251a such that the ferrite sheet 1212 is spaded apart from the antenna coil 1211.
The ferrite sheet 1212 may be formed between the touch sensor 1260 and the display 1251a to form a buffer. The ferrite sheet 1212 may extend along edges of the display 1251a to form a loop such that visual information is displayed on the display 1251a.

In this example, the ferrite sheet 1212 may form a buffer between the window 1251b and the display 1251a. 
With reference to FIG. 11, the antenna coil 1211 may be formed on a layer or a substrate different from that of the touch sensor 1260. In order to enhance performance of near field communication when the antenna coil 1211 overlaps with a pattern for touch sensing and a signal transmission line, the ferrite sheet 1212 (or a ferrite form) may be formed on a rear surface of the touch sensor 1260.
The ferrite sheet 1212 may have an annular shape, configured as a buffering damper made of a magnetic material, and the ferrite sheet 1212 may separate the touch sensor 1260 and the display 1251a. The ferrite sheet 1212 may have a thickness ranging from about 0.1 millimeter to 0.2 millimeter, for example.
The ferrite sheet 1212 may have a structure in which various metal compounds (assuming magnetism) have a form of paper that can be provided on one surface of the display 1251a. Since the antenna coil 1211 is wound around the structure (i.e., the window or the like) of the terminal and the ferrite sheet 1212 is attached to an electronic element (i.e., the display or the like) adjacent thereto, the ferrite sheet 1212 and the antenna coil 1211 (of the antenna device 1210) may be separately configured.
With reference to FIGS. 10 and 12, the flexible circuit board 1283 that is electrically connected to the antenna coil 1211 may form an electrical path that extends from the touch sensor 1260. The flexible circuit board 1283 may be connected to the touch sensor 1260 to transfer a signal based on sensing a touch to the circuit board 1281, and the flexible circuit board 1283 may also be electrically connected to the antenna coil 1211 to allow a signal of near field communication to be processed.
The flexible circuit board 1283 may include a first connection portion 1283a that is connected to the touch sensor 1260, and a second connection portion 1283b that is formed on a different layer from that of the first connection portion 1283a and is connected to the antenna coil 1211. According to such a stacking structure, respective signal paths of the antenna coil 1211 and the touch sensor 1260 at different positions in a thickness direction of the terminal may be implemented by the single flexible circuit board 1283.

In another example, the antenna film 1313 may be formed such that an antenna coil is attached on an optical film. The optical film may have a form having excellent optical performance having high light transmittance, and having a small thickness, for example.
In another example, the antenna film 1313 may be formed such that an antenna coil is formed on a pattern film mounted on the window 1351b.

An antenna coil 1511 may be formed on a surface of any one of the electrode films 1561 and 1562. For example, a conductive pattern may be formed on one surface of the first electrode film 1561 to sense a touch, and the antenna coil 1511 may be formed on an opposite surface of the first electrode film 1561. Alternatively, the antenna coil 1511 may be disposed on the opposite surface of a surface on which the conductive pattern is formed.

According to this structure, a magnetic field that is strong and uniformly distributed may be generated, and an effect of extending a communication distance to a reader may be obtained according to experimentation.
In an embodiment, since an antenna coil is formed along edges of a window, near field communication through a front surface of the mobile terminal may be implemented.
