1. Field of the Invention
The present disclosure relates to a mobile terminal having a display unit consisting of a plurality of regions, and a control method thereof.
2. Description of the Related Art
Terminals may be generally classified into mobile/portable terminals or stationary terminals according to their mobility. Mobile terminals may also be classified as handheld terminals or vehicle mounted terminals according to whether or not a user can directly carry the terminal.
Mobile terminals have become increasingly more functional. Examples of such functions include data and voice communications, capturing images and video via a camera, recording audio, playing music files via a speaker system, and displaying images and video on a display. Some mobile terminals include additional functionality which supports game playing, while other terminals are configured as multimedia players. More recently, mobile terminals have been configured to receive broadcast and multicast signals which permit viewing of content such as videos and television programs.
As it becomes multifunctional, a mobile terminal can be allowed to capture still images or moving images, play music or video files, play games, receive broadcast and the like, so as to be implemented as an integrated multimedia player.
Efforts are ongoing to support and increase the functionality of mobile terminals. Such efforts include software and hardware improvements, as well as changes and improvements in the structural components.
Due to the functional support and improvement of mobile terminals and the enhancement of multimedia functions, the size of the display unit has increased and the image quality has also increased to have high-resolution, thereby requiring a lot of power consumption to drive the display unit of the mobile terminal.
In general, when the display unit is activated, the entire screen thereof may be activated to consume substantially constant power all the time. Accordingly, there is a drawback of increasing the power consumption of a battery as increasing the active period of time.

Here, the wireless signals may include audio call signal, video (telephony) call signal, or various formats of data according to transmission/reception of text/multimedia messages.
The wireless Internet module 113 denotes a module for wireless Internet access. This module may be internally or externally coupled to the mobile terminal 100. The wireless Internet module 113 may transmit/receive wireless signals via communication networks according to wireless Internet technologies.
Examples of such wireless Internet access may include Wireless LAN (WLAN), Wireless-Fidelity (Wi-Fi), Wireless Fidelity Direct (Wi-Fi Direct), Digital Living Network Alliance (DLNA), Wireless Broadband (WiBro), World Interoperability for Microwave Access (WiMAX), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), LTE (Long Term Evolution), LTE-A (Long Term Evolution-Advanced), and the like. The wireless Internet module 113 may transmit/receive data according to at least one wireless Internet technology within a range including even Internet technologies which are not aforementioned.
From the perspective that the wireless Internet accesses according to Wibro, HSDPA, GSM, CDMA, WCDMA, LTE, LTE-A and the like are executed via a mobile communication network, the wireless Internet module 113 which performs the wireless Internet access via the mobile communication network may be understood as a type of the mobile communication module 112.
The short-range communication module 114 denotes a module for short-range communications. Suitable technologies for implementing the short-range communications may include BLUETOOTH™, Radio Frequency IDentification (RFID), Infrared Data Association (IrDA), Ultra-WideBand (UWB), ZigBee, Near Field Communication (NFC), Wireless-Fidelity (Wi-Fi), Wi-Fi Direct, Wireless Universal Serial Bus (Wireless USB) and the like.

Here, the another mobile terminal 100 may be a wearable device, for example, a smart watch, a smart glass or a head mounted display (HMD), which is able to exchange data with the mobile terminal 100 (or to cooperate with the mobile terminal 100). The short-range communication module 114 may sense (recognize) a wearable device, which is able to communicate with the mobile terminal), near the mobile terminal 100. In addition, when the sensed wearable device is a device which is authenticated to communicate with the mobile terminal 100 according to the present disclosure, the controller 180 may transmit at least part of data processed in the mobile terminal 100 to the wearable device via the short-range communication module 114.

As another example, when the mobile terminal uses the Wi-Fi module, a position of the mobile terminal may be acquired based on information related to a wireless access point (AP) which transmits or receives a wireless signal to or from the Wi-Fi module. According to the need, the location information module 115 may perform any function of the other modules of the wireless communication unit 110 to obtain data on the location of the mobile terminal. As a module used to acquire the location (or current location) of the mobile terminal, the location information module 115 may not be necessarily limited to a module for directly calculating or acquiring the location of the mobile terminal.
Hereinafter, the input unit 120 will be described in more detail. The input unit 120 may be configured to provide an audio or video signal (or information) input to the mobile terminal or information input by a user to the mobile terminal. For the input of the audio information, the mobile terminal 100 may include one or a plurality of cameras 121. The camera 121 may process image frames of still pictures or video obtained by image sensors in a video call mode or a capture mode. The processed image frames may be displayed on the display unit 151. On the other hand, the plurality of cameras 121 disposed in the mobile terminal 100 may be arranged in a matrix configuration. By use of the cameras 121 having the matrix configuration, a plurality of image information having various angles or focal points may be input into the mobile terminal 100. Also, the plurality of cameras 121 may be arranged in a stereoscopic structure to acquire a left image and a right image for implementing a stereoscopic image.
The microphone 122 may process an external audio signal into electric audio data. The processed audio data may be utilized in various manners according to a function being executed in the mobile terminal 100 (or an application program being executed). On the other hand, the microphone 122 may include assorted noise removing algorithms to remove noise generated in the course of receiving the external audio signal.
The user input unit 123 may receive information input by a user. When information is input through the user input unit 123, the controller 180 may control an operation of the mobile terminal 100 to correspond to the input information. The user input unit 123 may include a mechanical input element (or a mechanical key, for example, a button located on a front/rear surface or a side surface of the mobile terminal 100, a dome switch, a jog wheel, a jog switch, etc.), and a touch-sensitive input means. As one example, the touch-sensitive input means may be a virtual key, a soft key or a visual key, which is displayed on a touch screen through software processing, or a touch key which is disposed on a portion except for the touch screen. On the other hand, the virtual key or the visual key may be displayable on the touch screen in various shapes, for example, graphic, text, icon, video or a combination thereof.
The sensing unit 140 may sense at least one of internal information of the mobile terminal, surrounding environment information of the mobile terminal and user information, and generate a sensing signal corresponding to it. The controller 180 may control an operation of the mobile terminal 100 or execute data processing, a function or an operation associated with an application program installed in the mobile terminal based on the sensing signal. Hereinafter, description will be given in more detail of representative sensors of various sensors which may be included in the sensing unit 140.
First, a proximity sensor 141 refers to a sensor to sense presence or absence of an object approaching to a surface to be sensed, or an object disposed near a surface to be sensed, by using an electromagnetic field or infrared rays without a mechanical contact. The proximity sensor 141 may be arranged at an inner region of the mobile terminal covered by the touch screen, or near the touch screen. The proximity sensor 141 may have a longer lifespan and a more enhanced utility than a contact sensor.
The proximity sensor 141, for example, may include a transmissive type photoelectric sensor, a direct reflective type photoelectric sensor, a mirror reflective type photoelectric sensor, a high-frequency oscillation proximity sensor, a capacitance type proximity sensor, a magnetic type proximity sensor, an infrared rays proximity sensor, and so on. When the touch screen is implemented as a capacitance type, the proximity sensor 141 may sense proximity of a pointer to the touch screen by changes of an electromagnetic field, which is responsive to an approach of an object with conductivity. In this case, the touch screen (touch sensor) may be categorized into a proximity sensor.
Hereinafter, for the sake of brief explanation, a status that the pointer is positioned to be proximate onto the touch screen without contact will be referred to as ‘proximity touch,’ whereas a status that the pointer substantially comes in contact with the touch screen will be referred to as ‘contact touch.’ For the position corresponding to the proximity touch of the pointer on the touch screen, such position will correspond to a position where the pointer faces perpendicular to the touch screen upon the proximity touch of the pointer. The proximity sensor 141 may sense proximity touch, and proximity touch patterns (e.g., distance, direction, speed, time, position, moving status, etc.). On the other hand, the controller 180 may process data (or information) corresponding to the proximity touches and the proximity touch patterns sensed by the proximity sensor 141, and output visual information corresponding to the process data on the touch screen. In addition, the controller 180 may control the mobile terminal 100 to execute different operations or process different data (or information) according to whether a touch with respect to the same point on the touch screen is either a proximity touch or a contact touch.
A touch sensor may sense a touch (or touch input) applied onto the touch screen (or the display unit 151) using at least one of various types of touch methods, such as a resistive type, a capacitive type, an infrared type, a magnetic field type, and the like.
As one example, the touch sensor may be configured to convert changes of pressure applied to a specific part of the display unit 151 or a capacitance occurring from a specific part of the display unit 151, into electric input signals. Also, the touch sensor may be configured to sense not only a touched position and a touched area, but also touch pressure. Here, a touch object is an object to apply a touch input onto the touch sensor. Examples of the touch object may include a finger, a touch pen, a stylus pen, a pointer or the like.
When touch inputs are sensed by the touch sensors, corresponding signals may be transmitted to a touch controller. The touch controller may process the received signals, and then transmit corresponding data to the controller 180. Accordingly, the controller 180 may sense which region of the display unit 151 has been touched. Here, the touch controller may be a component separate from the controller 180 or the controller 180 itself.
On the other hand, the controller 180 may execute a different control or the same control according to a type of an object which touches the touch screen (or a touch key provided in addition to the touch screen). Whether to execute the different control or the same control according to the object which gives a touch input may be decided based on a current operating state of the mobile terminal 100 or a currently executed application program.
On the other hand, the touch sensor may be formed to sense a touch input using a different scheme in an active or inactive state of the display unit 151. At this time, the different scheme may be associated with an active period of the touch sensor. More specifically, the touch sensor may be activated with a different period according to whether or not the display unit 151 is activated. In other words, the touch sensor may have a different active period according to whether or not the display unit 151 is activated to sense a touch input applied to the touch sensor.
For example, when the display unit 151 is in an inactive state, the touch sensor may be activated with a preset specific period. In this case, the specific period may be a period corresponding to a time greater than zero. Furthermore, when the display unit 151 is in an active state, the touch sensor may be always operated in an active state. In other words, in this case, an activated period of the touch sensor may be a period having a time zero or very close to zero.
Whether or not the touch sensor is activated may be determined using the power consumption of the touch sensor. For example, the touch sensor may correspond to an inactive state when the power consumption of the touch sensor is less than a preset reference value based on zero, and may be referred to as an active state when the power consumption of the touch sensor is greater than a preset reference value based on zero.
When the display unit 151 is in an active state (hereinafter, referred to as an “active mode”), the touch sensor may continuously maintain the active state, and wait form the application of a touch input to the display unit 151. On the contrary, when the display unit 151 is in an inactive state (hereinafter, referred to as a “doze mode”), the touch sensor may be activated for each a preset specific period.
On the other hand, as reducing a specific period in which the touch sensor is activated, a speed for sensing a touch input hitting the display unit 151 may increase, but accordingly power consumed by the touch sensor may also increase. On the contrary, as increasing the period in which the touch sensor is activated, a speed for sensing a touch input hitting the display unit 151 may decrease though power consumed by the touch sensor decreases.
Accordingly, the specific period may be set to enhance the efficiency of power consumption while the sensing speed is fast enough to the extent that cannot be recognized by the user in sensing a touch input hitting the display unit 151. For example, the specific period may be set such that the touch sensor is inactive and then active 20 times (Hz) per second.
On the other hand, while the display unit 151 is in an active state, the touch sensor may be also activated, and the active period (T) in an active state may be zero or very close to zero. Otherwise, the period of the touch sensor while the touch sensor is in an active state may be shorter several times than a specific period set to activate the touch sensor while the display unit 151 is in an inactive state.
On the other hand, when a preset touch input (for example, a first and a second touch input consecutively hitting a predetermined region within a reference period of time) is sensed by the touch sensor in a doze mode in which the display unit 151 is deactivated and the touch sensor is periodically activated, the controller 180 may switch the doze mode to an active mode in which the display unit and touch sensor are activated.
In addition, the touch sensor may be driven with a different period based on the state of the display unit 151. For example, the touch sensor may execute a doze mode when the display unit 151 is in a closed state, and execute an active mode when switching from the closed state to an open state.
Meanwhile, the touch sensor and the proximity sensor may be executed individually or in combination, to sense various types of touches, such as a short (or tap) touch, a long touch, a multi-touch, a drag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swype touch, a hovering touch, and the like.
An ultrasonic sensor may be configured to recognize position information relating to a sensing object by using ultrasonic waves. The controller 180 may calculate a position of a wave generation source based on information sensed by an illumination sensor and a plurality of ultrasonic sensors. Since light is much faster than ultrasonic waves, a time for which the light reaches the optical sensor may be much shorter than a time for which the ultrasonic wave reaches the ultrasonic sensor. The position of the wave generation source may be calculated using the fact. In more detail, the position of the wave generation source may be calculated by using a time difference from the time that the ultrasonic wave reaches based on the light as a reference signal.
The camera 121 constructing the input unit 120 may be a type of camera sensor. The camera sensor may include at least one of a photo sensor (or image sensor) and a laser sensor.
The camera 121 and the laser sensor may be combined to detect a touch of the sensing object with respect to a 3D stereoscopic image. The photo sensor may be laminated on the display device. The photo sensor may be configured to scan a movement of the sensing object in proximity to the touch screen. In more detail, the photo sensor may include photo diodes and transistors at rows and columns to scan content placed on the photo sensor by using an electrical signal which changes according to the quantity of applied light. Namely, the photo sensor may calculate the coordinates of the sensing object according to variation of light to thus obtain position information of the sensing object.
The display unit 151 may output information processed in the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven in the mobile terminal 100 or user interface (UI) and graphic user interface (GUI) information in response to the execution screen information.
The display unit 151 may also be implemented as a stereoscopic display unit for displaying stereoscopic images.
The stereoscopic display unit 152 may employ a stereoscopic display scheme such as stereoscopic scheme (a glass scheme), an auto-stereoscopic scheme (glassless scheme), a projection scheme (holographic scheme), or the like.
The audio 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 mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. Also, the audio output module 152 may also provide audible output signals related to a particular function (e.g., a call signal reception sound, a message reception sound, etc.) performed by the mobile terminal 100. The audio output module 152 may include a receiver, a speaker, a buzzer or the like.
A haptic module 153 may generate various tactile effects the that user may feel. A typical example of the tactile effect generated by the haptic module 153 may be vibration. Strength, pattern and the like of the vibration generated by the haptic module 153 may be controllable by a user selection or setting of the controller. For example, the haptic module 153 may output different vibrations in a combining manner or a sequential manner.
Besides vibration, the haptic module 153 may generate various other tactile effects, including an effect by stimulation such as a pin arrangement vertically moving with respect to a contact skin, a spray force or suction force of air through a jet orifice or a suction opening, a touch on the skin, a contact of an electrode, electrostatic force, etc., an effect by reproducing the sense of cold and warmth using an element that can absorb or generate heat, and the like.
The haptic module 153 may be implemented to allow the user to feel a tactile effect through a muscle sensation such as the user's fingers or arm, as well as transferring the tactile effect through a direct contact. Two or more haptic modules 153 may be provided according to the configuration of the mobile terminal 100.
An optical output module 154 may output a signal for indicating an event generation using light of a light source. Examples of events generated in the mobile terminal 100 may include a message reception, a call signal reception, a missed call, an alarm, a schedule notice, an email reception, an information reception through an application, and the like.
A signal output by the optical output module 154 may be implemented in such a manner that the mobile terminal emits monochromatic light or light with a plurality of colors. The signal output may be terminated as the mobile terminal senses a user's event checking.
The interface unit 160 may serve as an interface with every external device connected with the mobile terminal 100. For example, the interface unit 160 may receive data transmitted from an external device, receive power to transfer to each element within the mobile terminal 100, or transmit internal data of the mobile terminal 100 to an external device. For example, the interface unit 160 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, or the like.
The identification module may be a chip that stores various information for authenticating authority of using the mobile terminal 100 and may include a user identity module (UIM), a subscriber identity module (SIM), a universal subscriber identity module (USIM), and the like. In addition, the device having the identification module (referred to as ‘identifying device’, hereinafter) may take the form of a smart card. Accordingly, the identifying device may be connected with the terminal 100 via the interface unit 160.
When the mobile terminal 100 is connected with an external cradle, the interface unit 160 may serve as a passage to allow power from the cradle to be supplied to the mobile terminal 100 therethrough or may serve as a passage to allow various command signals input by the user from the cradle to be transferred to the mobile terminal therethrough. Various command signals or power input from the cradle may operate as signals for recognizing that the mobile terminal is properly mounted on the cradle.
The memory 170 may store programs for operations of the controller 180 and temporarily store input/output data (for example, phonebook, messages, still images, videos, etc.). The memory 170 may store data related to various patterns of vibrations and audio which are output in response to touch inputs on the touch screen.
The memory 170 may include at least one type of storage medium including 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 an optical disk. Also, the mobile terminal 100 may be operated in relation to a web storage device that performs the storage function of the memory 170 over the Internet.
As aforementioned, the controller 180 may typically control the general operations of the mobile terminal 100. For example, the controller 180 may set or release a lock state for restricting a user from inputting a control command with respect to applications when a status of the mobile terminal meets a preset condition.
The controller 180 may also perform controlling and processing associated with voice calls, data communications, video calls, and the like, or perform pattern recognition processing to recognize a handwriting input or a picture drawing input performed on the touch screen as characters or images, respectively. In addition, the controller 180 may control one or combination of those components in order to implement various exemplary embodiment disclosed herein on the mobile terminal 100.
The power supply unit 190 may receive external power or internal power and supply appropriate power required for operating respective elements and components included in the mobile terminal 100 under the control of the controller 180. The power supply unit 190 may include a battery. The battery may be an embedded battery which is rechargeable or be detachably coupled to the terminal body for charging.
The power supply unit 190 may include a connection port. The connection port may be configured as one example of the interface unit 160 to which an external (re)charger for supplying power to recharge the battery is electrically connected.
As another example, the power supply unit 190 may be configured to recharge the battery in a wireless manner without use of the connection port. Here, the power supply unit 190 may receive power, transferred from an external wireless power transmitter, using at least one of an inductive coupling method which is based on magnetic induction or a magnetic resonance coupling method which is based on electromagnetic resonance.
Various embodiments described herein may be implemented in a computer-readable or its similar medium using, for example, software, hardware, or any combination thereof.
Referring to
Here, the terminal body may be understood as a conception which indicates the mobile terminal 100 as at least one assembly.
The mobile terminal 100 may include a case (casing, housing, cover, etc.) forming the appearance of the terminal. In this embodiment, the case may be divided into a front case 101 and a rear case 102. Various electronic components may be incorporated into a space formed between the front case 101 and the rear case 102. At least one middle case may be additionally disposed between the front case 101 and the rear case 102
A display unit 151 may be disposed on a front surface of the terminal body to output information. As illustrated, a window 151 a of the display unit 151 may be mounted to the front case 101 so as to form the front surface of the terminal body together with the front case 101.
In some cases, electronic components may also be mounted to the rear case 102. Examples of those electronic components mounted to the rear case 102 may include a detachable battery, an identification module, a memory card and the like. Here, a rear cover 103 for covering the electronic components mounted may be detachably coupled to the rear case 102. Therefore, when the rear cover 103 is detached from the rear case 102, the electronic components mounted to the rear case 102 may be externally exposed.
As illustrated, when the rear cover 103 is coupled to the rear case 102, a side surface of the rear case 102 may be partially exposed. In some cases, upon the coupling, the rear case 102 may also be completely shielded by the rear cover 103. On the other hand, the rear cover 103 may include an opening for externally exposing a camera 121b or an audio output module 152b.
The cases 101, 102, 103 may be formed by injection-molding synthetic resin or may be formed of a metal, for example, stainless steel (STS), titanium (Ti), or the like.
Unlike the example which the plurality of cases form an inner space for accommodating such various components, the mobile terminal 100 may be configured such that one case forms the inner space. In this example, a mobile terminal 100 having a uni-body formed in such a manner that synthetic resin or metal extends from a side surface to a rear surface may also be implemented.
On the other hand, the mobile terminal 100 may include a waterproofing unit (not shown) for preventing an introduction of water into the terminal body. For example, the waterproofing unit may include a waterproofing member which is located between the window 151a and the front case 101, between the front case 101 and the rear case 102, or between the rear case 102 and the rear cover 103, to hermetically seal an inner space when those cases are coupled.
The mobile terminal 100 may include a display unit 151, first and second audio output modules 152a and 152b, a proximity sensor 141, an illumination sensor 152, an optical output module 154, first and second cameras 121a and 121b, first and second manipulation units 123a and 123b, a microphone 122, an interface unit 160 and the like.
Hereinafter, description will be given of an exemplary mobile terminal 100 that the display unit 151, the first audio output module 152a, the proximity sensor 141, the illumination sensor 142, the optical output module 154, the first camera 121a and the first manipulation unit 123a are disposed on the front surface of the terminal body, the second manipulation unit 123b, the microphone 122 and the interface unit 160 are disposed on a side surface of the terminal body, and the second audio output module 152b and the second camera 121b are disposed on a rear surface of the terminal body, with reference to
Here, those components may not be limited to the arrangement, but be excluded or arranged on another surface if necessary. For example, the first manipulation unit 123a may not be disposed on the front surface of the terminal body, and the second audio output module 152b may be disposed on the side surface other than the rear surface of the terminal body.
For another embodiment, a plurality of cameras may be disposed on a front surface. Specifically, a dual camera may be disposed on a front surface of the terminal body.
The display unit 151 may output information processed in the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program driven in the mobile terminal 100 or user interface (UI) and graphic user interface (GUI) information in response to the execution screen information.
The display unit 151 may include at least one of a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light emitting diode (OLED), a flexible display, a 3-dimensional (3D) display, and an e-ink display.
The display unit 151 may be implemented in two or more in number according to a configured aspect of the mobile terminal 100. For instance, a plurality of the display units 151 may be arranged on one surface to be spaced apart from or integrated with each other, or may be arranged on different surfaces.
The display unit 151 may include a touch sensor which senses a touch onto the display unit so as to receive a control command in a touching manner. When a touch is input to the display unit 151, the touch sensor may be configured to sense this touch and the controller 180 may generate a control command corresponding to the touch. The content which is input in the touching manner may be a text or numerical value, or a menu item which can be indicated or designated in various modes.
The touch sensor may be configured in a form of film having a touch pattern. The touch sensor may be a metal wire, which is disposed between the window 151a and a display (not shown) on a rear surface of the window 151a or patterned directly on the rear surface of the window 151a. Or, the touch sensor may be integrally formed with the display. For example, the touch sensor may be disposed on a substrate of the display or within the display.
The display unit 151 may form a touch screen together with the touch sensor. Here, the touch screen may serve as the user input unit 123 (see
The first audio output module 152a may be implemented in the form of a receiver for transferring voice sounds to the user's ear or a loud speaker for outputting various alarm sounds or multimedia reproduction sounds.
The window 151a of the display unit 151 may include a sound hole for emitting sounds generated from the first audio output module 152a. Here, the present disclosure may not be limited to this. It may also be configured such that the sounds are released along an assembly gap between the structural bodies (for example, a gap between the window 151a and the front case 101). In this case, a hole independently formed to output audio sounds may not be seen or hidden in terms of appearance, thereby further simplifying the appearance of the mobile terminal 100.
The optical output module 154 may output light for indicating an event generation. Examples of the event generated in the mobile terminal 100 may include a message reception, a call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like. When a user's event checking is sensed, the controller may control the optical output unit 154 to stop the output of the light.
The first camera 121a may process video frames such as still or moving images obtained by the image sensor in a video call mode or a capture mode. The processed video frames may be displayed on the display unit 151 or stored in the memory 170.
The first and second manipulation units 123a and 123b are examples of the user input unit 123, which may be manipulated by a user to input a command for controlling the operation of the mobile terminal 100. The first and second manipulation units 123a and 123b may also be commonly referred to as a manipulating portion, and may employ any method if it is a tactile manner allowing the user to perform manipulation with a tactile feeling such as touch, push, scroll or the like.
The drawings are illustrated on the basis that the first manipulation unit 123a is a touch key, but the present disclosure may not be necessarily limited to this. For example, the first manipulation unit 123a may be configured with a mechanical key, or a combination of a touch key and a push key.
The content received by the first and second manipulation units 123a and 123b may be set in various ways. For example, the first manipulation unit 123a may be used by the user to input a command such as menu, home key, cancel, search, or the like, and the second manipulation unit 123b may be used by the user to input a command, such as controlling a volume level being output from the first or second audio output module 152a or 152b, switching into a touch recognition mode of the display unit 151, or the like.
On the other hand, as another example of the user input unit 123, a rear input unit (not shown) may be disposed on the rear surface of the terminal body. The rear input unit may be manipulated by a user to input a command for controlling an operation of the mobile terminal 100. The content input may be set in various ways. For example, the rear input unit may be used by the user to input a command, such as power on/off, start, end, scroll or the like, controlling a volume level being output from the first or second audio output module 152a or 152b, switching into a touch recognition mode of the display unit 151, or the like. The rear input unit may be implemented into a form allowing a touch input, a push input or a combination thereof.
The rear input unit may be disposed to overlap the display unit 151 of the front surface in a thickness direction of the terminal body. As one example, the rear input unit may be disposed on an upper end portion of the rear surface of the terminal body such that a user can easily manipulate it using a forefinger when the user grabs the terminal body with one hand. However, the present disclosure may not be limited to this, and the position of the rear input unit may be changeable.
When the rear input unit is disposed on the rear surface of the terminal body, a new user interface may be implemented using the rear input unit. Also, the aforementioned touch screen or the rear input unit may substitute for at least part of functions of the first manipulation unit 123a located on the front surface of the terminal body. Accordingly, when the first manipulation unit 123a is not disposed on the front surface of the terminal body, the display unit 151 may be implemented to have a larger screen.
On the other hand, the mobile terminal 100 may include a finger scan sensor which scans a user's fingerprint. The controller may use fingerprint information sensed by the finger scan sensor as an authentication means. The finger scan sensor may be installed in the display unit 151 or the user input unit 123.
The microphone 122 may be formed to receive the user's voice, other sounds, and the like. The microphone 122 may be provided at a plurality of places, and configured to receive stereo sounds.
The interface unit 160 may serve as a path allowing the mobile terminal 100 to exchange data with external devices. For example, the interface unit 160 may be at least one of a connection terminal for connecting to another device (for example, an earphone, an external speaker, or the like), a port for near field communication (for example, an Infrared Data Association (IrDA) port, a Bluetooth port, a wireless LAN port, and the like), or a power supply terminal for supplying power to the mobile terminal 100. The interface unit 160 may be implemented in the form of a socket for accommodating an external card, such as Subscriber Identification Module (SIM), User Identity Module (UIM), or a memory card for information storage.
The second camera 121b may be further mounted to the rear surface of the terminal body. The second camera 121b may have an image capturing direction, which is substantially opposite to the direction of the first camera unit 121a.
The second camera 121b may include a plurality of lenses arranged along at least one line. The plurality of lenses may also be arranged in a matrix configuration. The cameras may be referred to as an ‘array camera.’ When the second camera 121b is implemented as the array camera, images may be captured in various manners using the plurality of lenses and images with better qualities may be obtained.
For another embodiment, a plurality of cameras may be disposed on a rear surface. Specifically, a dual camera may be disposed on a rear surface of the terminal body.
A flash 124 may be disposed adjacent to the second camera 121b. When an image of a subject is captured with the camera 121b, the flash 124 may illuminate the subject.
The second audio output module 152b may further be disposed on the terminal body. The second audio output module 152b may implement stereophonic sound functions in conjunction with the first audio output module 152a (refer to
At least one antenna for wireless communication may be disposed on the terminal body. The antenna may be installed in the terminal body or formed on the case. For example, an antenna which configures a part of the broadcast receiving module 111 (see
A power supply unit 190 (refer to
The battery 191 may receive power via a power source cable connected to the interface unit 160. Also, the battery 191 may be (re)chargeable in a wireless manner using a wireless charger. The wireless charging may be implemented by magnetic induction or electromagnetic resonance.
On the other hand, the drawing illustrates that the rear cover 103 is coupled to the rear case 102 for shielding the battery 191, so as to prevent separation of the battery 191 and protect the battery 191 from an external impact or foreign materials. When the battery 191 is detachable from the terminal body, the rear case 103 may be detachably coupled to the rear case 102.
An accessory for protecting an appearance or assisting or extending the functions of the mobile terminal 100 may further be provided on the mobile terminal 100. As one example of the accessory, a cover or pouch for covering or accommodating at least one surface of the mobile terminal 100 may be provided. The cover or pouch may cooperate with the display unit 151 to extend the function of the mobile terminal 100. Another example of the accessory may be a touch pen for assisting or extending a touch input onto a touch screen.
Hereinafter, a communication system which is operable with the mobile terminal 100 according to the present disclosure will be described.
First, such communication system utilizes different air interfaces and/or physical layers. Examples of such air interfaces utilized by the communication system include Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), Universal Mobile Telecommunications System (UMTS) (especially, Long Term Evolution (LTE)), Global System for Mobile Communications (GSM), and the like.
By way of non-limiting example only, further description will relate to a CDMA communication system, but such teachings apply equally to other system types including a CDMA wireless communication system.
A CDMA wireless communication system includes one or more mobile terminals 100, one or more base stations (BSs), one or more base station controllers (BSCs), and a mobile switching center (MSC). The MSC is configured to interface with a conventional Public Switched Telephone Network (PSTN) and the BSCs. The BSCs are coupled to the base stations via backhaul lines. The backhaul lines may be configured in accordance with any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. Hence, the plurality of BSCs can be included in the CDMA wireless communication system.
Each base station may include one or more sectors, each sector having an omni-directional antenna or an antenna pointed in a particular direction radially away from the base station. Alternatively, each sector may include two or more different antennas. Each base station may be configured to support a plurality of frequency assignments, with each frequency assignment having a particular spectrum (e.g., 1.25 MHz, 5 MHz, etc.).
The intersection of sector and frequency assignment may be referred to as a CDMA channel. The base stations may also be referred to as Base Station Transceiver Subsystems (BTSs). In some cases, the term “base station” may be used to refer collectively to a BSC, and one or more base stations. The base stations may also be denoted as “cell sites.” Alternatively, individual sectors of a given base station may be referred to as cell sites.
A broadcasting transmitter (BT) transmits a broadcast signal to the mobile terminals 100 operating within the system. The broadcast receiving module 111 of
Global Positioning System (GPS) satellites for locating the position of the mobile terminal 100 may cooperate with the CDMA wireless communication system. Such satellites 300 facilitate locating the position of the mobile terminal 100. Useful position information may be obtained with greater or fewer satellites than two satellites. It is to be appreciated that other types of position detection technology, (i.e., location technology that may be used in addition to or instead of GPS location technology) may alternatively be implemented. If desired, at least one of the GPS satellites may alternatively or additionally be configured to provide satellite DMB transmissions.
A location information module 115 of the mobile terminal is configured to acquire a position of the mobile terminal. Such location information module 115 may include a Global Position System (GPS) module and a Wireless Fidelity (Wi-Fi) module. According to the need, the location information module 115 may perform any function of another module of the wireless communication unit 110 to obtain data for the location of the mobile terminal in a substitutional or additional manner.
The GPS module 115 may measure an accurate time and distance from three or more satellites, and accurately calculate a current location of the mobile terminal according to trigonometry based on the measured time and distances. A method of acquiring distance and time information from three satellites and performing error correction with a single satellite may be used. In particular, the GPS module may acquire an accurate time together with three-dimensional speed information as well as the location of the latitude, longitude and altitude values from the location information received from the satellites. Furthermore, the GPS module may acquire speed information by real time calculating a current position. It is difficult to precisely measure a position of the mobile terminal using the GPS module, in a blind spot of satellite signals such as an indoor space. In order to compensate for the positioning technique using such GPS module, a Wi-Fi Positioning System (WPS) may be utilized.
The Wi-Fi positioning system (WPS) refers to a location determination technology based on a wireless local area network (WLAN) using Wi-Fi as a technology for tracking the location of the mobile terminal 100 using a Wi-Fi module provided in the mobile terminal 100 and a wireless access point for transmitting and receiving to and from the Wi-Fi module.
The Wi-Fi positioning system may include a Wi-Fi location determination server, a mobile terminal 100, a wireless access point (AP) connected to the mobile terminal, and a database stored with any wireless AP information.
The mobile terminal 100 connected to the wireless AP may transmit a location information request message to the Wi-Fi location determination server.
The Wi-Fi location determination server extracts the 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 may be transmitted to the Wi-Fi location determination server through the mobile terminal 100, or may be transmitted to the Wi-Fi location determination server from the wireless AP.
The information of the wireless AP extracted based on the location information request message of the mobile terminal 100 may be at least one of MAC address, Service Set IDentification (SSID), Received Signal Strength Indicator (RSSI), Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), channel information, privacy, network type, signal strength and noise strength.
The Wi-Fi location determination server may receive the information of the wireless AP connected to the mobile terminal 100 as described above, and may extract wireless AP information corresponding to the wireless AP connected to the mobile terminal from the pre-established database. The information of any wireless APs stored in the database may be information such as MAC address, SSID, RSSI, channel information, privacy, network type, latitude and longitude coordinate, building at which the wireless AP is located, floor number, detailed indoor location information (GPS coordinate available), AP owner's address, phone number, and the like. In order to remove wireless APs provided using a mobile AP or an illegal MAC address during a location determining process, the Wi-Fi location determination server may extract only a predetermined number of wireless AP information in order of high RSSI.
Then, the Wi-Fi location determination server may extract (analyze) location information of the mobile terminal 100 using at least one wireless AP information extracted from the database. Information included therein is compared with the received wireless AP information to extract (analyze) the location information of the mobile terminal 100.
A method for extracting (analyzing) location information of the mobile terminal 100 may include a Cell-ID method, a fingerprint method, a trigonometry method, a landmark method, etc.
The Cell-ID method is used to determine a position of a wireless AP having the largest signal strength, among peripheral wireless AP information collected by a mobile terminal, as a position of the mobile terminal. The Cell-ID method is advantageous in that an implementation is simple, additional costs are not required, and location information can be rapidly acquired. However, the Cell-ID method is disadvantageous in that precision of positioning is lowered when an installation density of a wireless AP is low.
The fingerprint method is used to collect signal strength information by selecting a reference position from a service area, and to track a position of a mobile terminal using the signal strength information transmitted from the mobile terminal based on the collected information. In order to use the fingerprint method, characteristics of radio signals should be pre-stored in the form of database.
The trigonometry method is used to calculate a position of a mobile terminal, based on a distance between coordinates of at least three wireless APs and the mobile terminal. In order to measure the distance between the mobile terminal and the wireless AP, signal strength may be converted into distance information, or Time of Arrival (ToA) taken for wireless signals to be transmitted may be used.
The landmark method is used to measure a position of a mobile terminal using a known landmark transmitter.
Besides the above methods, various algorithms may be used to extract (analyze) location information of a mobile terminal.
Such extracted location information of the mobile terminal 100 is transmitted to the mobile terminal 100 through the Wi-Fi location determination server, thereby acquiring location information of the mobile terminal 100.
The mobile terminal 100 may acquire location information by being connected to at least one wireless AP. The number of wireless APs required to acquire location information of the mobile terminal 100 may be variously changed according to a wireless communication environment where the mobile terminal 100 is positioned.
As aforementioned with reference to
An NFC module provided at the mobile terminal supports short-range wireless communication, a non-contactable type between mobile terminals, within about 10 cm. The NFC module may operate in one of a card mode, a reader mode and a P2P mode. The mobile terminal 100 may further include a security module for storing card information, in order to operate the NFC module in a card mode. The security module may be a physical medium such as UICC (Universal Integrated Circuit Card) (e.g., SIM (Subscriber Identification Module) or USIM (Universal SIM)), a secure micro SD and a sticker, or a logical medium (e.g., embedded SE (Secure Element)) embedded in the mobile terminal. SWP (Single Wire Protocol)-based data exchange may be performed between the NFC module and the security module.
In a case where the NFC module operates in a card mode, the mobile terminal may transmit card information on a general IC card to outside. More specifically, if a mobile terminal having therein card information on a payment card (e. g, a credit card or a bus card) is made to approach to a card reader, a short-range mobile payment may be executed. On the other hand, if a mobile terminal which stores card information on an entrance card is made to approach to an entrance card reader, an entrance approval procedure may start. A card such as a credit card, a traffic card and an entrance card may be mounted in the security module in the form of applet, and the security module may store card information on the card mounted therein. Card information of a payment card may be at least one of a card number, a remaining amount and a usage history. Card information of an entrance card may be at least one of a user's name, a user's number (e.g., undergraduate number or staff number) and an entrance history.
In a case where the NFC module operates in a reader mode, the mobile terminal may read data from an external tag. The data received from the external tag by the mobile terminal may be coded into the NFC Data Exchange Format defined by the NFC Forum. The NFC Forum defines four record types. More specifically, the NFC Forum defines four RTDs (Record Type Definitions) such as Smart Poster, Text, URI (Uniform Resource Identifier) and General Control. If the data received from the external tag is a smart poster type, the controller may execute a browser (e.g., Internet browser). If the data received from the external tag is a text type, the controller may execute a text viewer. If the data received from the external tag is a URI type, the controller may execute a browser or originate a call. If the data received from the external tag is a general control type, the controller may execute a proper operation according to control content.
In a case where the NFC module operates in a peer-to-peer (P2P) mode, the mobile terminal may execute P2P communication with another mobile terminal. In this case, LLCP (Logical Link Control Protocol) may be applied to the P2P communication. For the P2P communication, connection may be generated between the mobile terminal and said another mobile terminal. The connection may be categorized into a connectionless mode which ends after one packet is switched, and a connection-oriented mode in which packets are switched consecutively. For the P2P communication, data such as an electronic type name card, address information, a digital photo and a URL, a setup parameter for Bluetooth connection, Wi-Fi connection, etc. may be switched. The P2P mode can be effectively utilized in switching data of a small capacity, because an available distance for NFC communication is short.
As illustrated in
In other words, the display unit 200 has a structure in which one side thereof illustrated in
A first region 201 on the display unit 200 as a main region corresponds to the display unit 151 in
Accordingly, according to the circumstances, the present disclosure may selectively activate one of the two regions 201, 202, thereby reducing power consumption.
Typical image information may be displayed in the main region 201, and an event occurrence may be displayed or a status bar may be displayed in the extended region 202, and additional information may be displayed therein according to the type of an application displayed in the main region 201. In particular, status information may be displayed in the extended region when the main region 201 is in an inactive state (off state), and the status information may be displayed at an upper portion of the main region when the main region 201 is in an active state (on state).
Accordingly, when it is controlled that the main region 201 is deactivated and the extended region 202 is activated in a state that a user does not use the terminal, the user may check a status or newly occurred event of the mobile terminal through the extended region 202.
The extended region 202 may be formed to be less than or equal to a horizontal or vertical length of the main region 201 as illustrated in the drawing. According to the present disclosure, an example is given that a horizontal length of the extended region 202 is less than a horizontal length of the main region 201.
In this case, the camera 121, proximity sensor 141 and illumination sensor 142 that have been located an upper side of the display unit 151 in
As described above, a plurality of cameras may be disposed on a front or rear surface of the terminal body. Specifically, a dual camera 121-1, 121-2 may be disposed on a front or rear surface of the terminal body.
When a horizontal length of the extended region 202 is formed to be less than that of the main region 201, at least one side thereof may be formed in one of a rectangular shape, an inclined surface and a curved surface. In
The display unit 200 as a display panel is largely divided into a liquid crystal panel and a backlight unit. The backlight unit plays the role of uniformly providing light provided from a light source in a front direction of the display unit 200, and includes the light source, a light guide plate, a polarizing plate, a diffusion plate, and a reflection plate.
As illustrated in
The backlight unit supplies light to the light guide plate 225 through light sources located in two directions contrary to the related art. For example, a plurality of main light sources 227 disposed in parallel along a first lateral surface 225a of the light guide plate 225 may uniformly supply light over the entire light guide plate 225. The auxiliary light source 228 located at a second lateral surface 225b perpendicular to the first lateral surface 225a of the light guide plate 225 may supply light to part of the light guide plate 225.
The main light source 227 and auxiliary light source 228 may be independently driven to control that only the auxiliary light source 228 is turned on in a state that the main light source 227 is turned off.
An IC circuit illustrated in
A power source (VBAT) supplied from the power supply unit 190 is noise-removed through a bypass booster 187 and input to the backlight IC 186. The backlight IC 186 controls the light sources 227, 228 to emit light. The backlight IC 186 finds an optimal backlight brightness for displaying the relevant image based on the low data information of an image received from a drive IC 215 of the liquid crystal panel to adjust the brightness of each LED (Content Adaptive Brightness Control (CABC)).
When one backlight IC 186 is used, the present disclosure may use one more LED channel 186a to control the auxiliary light source 228 (
The plurality of main light sources 227 may be provided in parallel adjacent to the first lateral surface 225a to supply light to the entire light guide plate 225, but one or two auxiliary light sources 228 having a smaller number than that of the main light sources 227 may be provided to supply light only to part of the light guide plate 225.
The present disclosure may include a first light guide plate 2251 configured to emit light supplied from the main light source 227 to a front surface of the display unit 200 and a second light guide plate 2252 configured to emit light supplied from the auxiliary light source 228 to a front surface of the display unit 200 as illustrated in
When the light guide plate 225 is configured as an integral type as illustrated in
On the other hand, when the light guide plate 225 is configured as a separable type as illustrated in
The main light source 227 and auxiliary light source 228 may be connected to a main board in a merged manner or individually connected to the main board in a separate manner. Accordingly, according to the present disclosure, independently controlling the main region 201 and extended region 202 denotes that the controller 180 independently controls the main light source 227 and auxiliary light source 228.
The auxiliary light source 228 may be located at the second lateral surface 225b, thereby increasing the size of a bezel of the second lateral surface 225b. An increase of the bezel size due to the auxiliary light source 228 may not be a big problem in case of a large-sized display unit, but the bezel size may be a very important factor in determining the size of the entire product in a small-sized terminal.
Accordingly, according to the present disclosure, in order to prevent an increase of the bezel size in a lateral direction, the second lateral surface 225b of the light guide plate 225 at which the auxiliary light source 228 is located may be formed in a concave manner to form a dent 224. The auxiliary light source 228 may be located at the dent 224, thereby preventing the bezel size from being increased in a lateral direction.
On the other hand, an liquid crystal panel 210 constituting the display unit 200 has a similar size to that of the light guide plate 225. In other words, when the light guide plate 225 has a dent 224, the dent is formed on the same location.
According to the present disclosure, the light guide plate 225 may be divided into a portion corresponding to the main region 201 and a portion corresponding to the extended region 202, but the liquid crystal panel is provided with one unit and controlled by one drive IC. The drive IC is connected to a main board through a flexible board to apply power for each pixel according to an image signal received from the main board so as to adjust the alignment of liquid crystal molecules.
The liquid crystal panel is a device of selectively applying power for each pixel to change the alignment of liquid crystal molecules and display a different color for each pixel, thereby configuring an image. The display unit 200 configured with such a liquid crystal panel and a backlight unit may be disposed on a front surface of the mobile terminal 100 to display information according to the control of the controller 180 as illustrated in
The present disclosure may define an operation mode according to the type of driving the main region 201 and extended region 202. A first mode is a mode in which both the main region and extended region (201, 202) are in an active state, and a second mode is a mode in which only the extended region 202 is in an active state.
As illustrated in
A multiplexer is disposed between the drive IC and each transistor. The gate signal (GATE) and data signal (DATA) are transferred through the multiplexer, and the transferred signals (GATE, DATA) are sequentially redistributed ad supplied to each transistor.
The gate signal is comprised of a gate clock and a shift-resistor, and the shift-resistor performs the operation of receiving a clock to transfer data to the next gate. The data signal is a signal for driving the liquid crystal panel according to color information for each pixel, and a voltage larger than that of the gate signal is applied to a portion at which the alignment of liquid crystal molecules should be changed to transmit light supplied from the backlight unit in a front direction.
On the other hand, as illustrated in
However, the gate signal (GATE) should be applied even to the main region 201 for synchronization at predetermined intervals. However, since the data signal is not applied to the main region 201, the size of the gate signal may be set to a small value. For example, a gate signal of ±9 V may be used for the extended region 202, and a gate signal of ±5 V may be used for the main region 201 to change the alignment of liquid crystal molecules.
The present disclosure may provide a method of selectively activating a main region (screen) and an extended region (screen) on the display unit 200 in an inactive state (off state) through a touch input to link a content displayed in the main region and extended region.
The touch input is a touch of consecutively tapping a predetermined region within a reference period of time, and referred to as a knock code according to the present disclosure. The knock code is a dedicated code for activating the main region and extended region.
A user may apply a predetermined touch input (e.g., short touch input) prior to entering a knock code to activate a touch screen on the main region and extended region.
When a knock code is entered, the controller 180 may compare it with a preset knock code to release screen lock while at the same time turning on a liquid crystal panel (e.g., LCD) of the entered region (main region or extended region).
Hereinafter, embodiments related to a control method which can be implemented in the mobile terminal will be explained in more detail with reference to the attached drawings. It is obvious to those skilled in the art that the present features can be embodied in several forms without departing from the characteristics thereof.
Furthermore, hereinafter, according to the present disclosure, the main region 201 will be referred to as a “first region”, and the extended region 202 extended and formed in at least one direction of the main region will be referred to as a “second region.”

Furthermore, the control pad screen 1620-1 of music playback on which the brightness is increased to a predetermined level may be displayed in the second region 202.
In other words, the brightness of a used region to which a user's manipulation is currently applied may be set to high and the brightness of a non-used region may be set to low to reduce unnecessary power consumption.
Subsequently, when a touch input 1640 is applied to the execution screen 1610-2 of the music playback application with a low brightness, the brightness of the first region 201 may be increased and the brightness of the second region 202 may be decreased.
