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, for example, may include any of 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 the like. When the touch screen is implemented as a capacitance type, the proximity sensor 141 can sense proximity of a pointer relative 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 also be categorized as a proximity sensor.
The term “proximity touch” will often be referred to herein to denote the scenario in which a pointer is positioned to be proximate to the touch screen without contacting the touch screen. The term “contact touch” will often be referred to herein to denote the scenario in which a pointer makes physical contact with the touch screen. For the position corresponding to the proximity touch of the pointer relative to the touch screen, such position will correspond to a position where the pointer is perpendicular to the touch screen. The proximity sensor 141 may sense proximity touch, and proximity touch patterns (for example, distance, direction, speed, time, position, moving status, and the like). In general, controller 180 processes data corresponding to proximity touches and proximity touch patterns sensed by the proximity sensor 141, and cause output of visual information on the touch screen. In addition, the controller 180 can control the mobile terminal 100 to execute different operations or process different data (or information) according to whether a touch with respect to a point on the touch screen is either a proximity touch or a contact touch.
A touch sensor can sense a touch (or a touch input) applied to the touch screen, such as display unit 151, using any of a variety of touch methods. Examples of such touch methods include a resistive type, a capacitive type, an infrared type, and a magnetic field type, among others.
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 convert capacitance occurring at a specific part of the display unit 151, into electric input signals. The touch sensor may also be configured to sense not only a touched position and a touched region, but also touch pressure and/or touch capacitance. A touch object is generally used to apply a touch input to the touch sensor. Examples of typical touch objects include a finger, a touch pen, a stylus pen, a pointer, or the like.
When a touch input is sensed by a touch sensor, 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, the controller 180, and combinations thereof.
Meanwhile, the controller 180 may execute the same or different controls according to a type of touch object that touches the touch screen or a touch key provided in addition to the touch screen. Whether to execute the same or different control according to the object which provides a touch input may be decided based on a current operating state of the mobile terminal 100 or a currently executed application program, for example.
The touch sensor and the proximity sensor may be implemented individually, or in combination, to sense various types of touches. Such touches includes 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 swipe touch, a hovering touch, and the like.
If desired, an ultrasonic sensor may be implemented to recognize position information relating to a touch object using ultrasonic waves. The controller 180, for example, 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, the time for which the light reaches the optical sensor is much shorter than the time for which the ultrasonic wave reaches the ultrasonic sensor. The position of the wave generation source may be calculated using this fact. For instance, the position of the wave generation source may be calculated using the time difference from the time that the ultrasonic wave reaches the sensor based on the light as a reference signal.
The camera 121, which has been depicted as a component of the input unit 120, typically includes at least one a camera sensor (CCD, CMOS etc.), a photo sensor (or image sensors), and a laser sensor.
Implementing the camera 121 with a laser sensor may allow detection of a touch of a physical object with respect to a 3D stereoscopic image. The photo sensor may be laminated on, or overlapped with, the display device. The photo sensor may be configured to scan movement of the physical 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 received at the photo sensor using an electrical signal which changes according to the quantity of applied light. Namely, the photo sensor may calculate the coordinates of the physical object according to variation of light to thus obtain position information of the physical object.
The display unit 151 is generally configured to output information processed in the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program executing at the mobile terminal 100 or user interface (UI) and graphic user interface (GUI) information in response to the execution screen information.
Also, the display unit 151 may be implemented as a stereoscopic display unit for displaying stereoscopic images.
A typical stereoscopic display unit may employ a stereoscopic display scheme such as a stereoscopic scheme (a glass scheme), an auto-stereoscopic scheme (glassless scheme), a projection scheme (holographic scheme), or the like.
The audio output module 152 is generally configured to output audio data. Such audio data may be obtained from any of a number of different sources, such that the audio data may be received from the wireless communication unit 110 or may have been stored in the memory 170. The audio data may be output during modes such as a signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. The audio output module 152 can provide audible output 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 also be implemented as a receiver, a speaker, a buzzer, or the like.
A haptic module 153 can be configured to generate various tactile effects that a user feels, perceive, or otherwise experience. A typical example of a tactile effect generated by the haptic module 153 is vibration. The strength, pattern and the like of the vibration generated by the haptic module 153 can be controlled by user selection or setting by 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 can generate various other tactile effects, including an effect by stimulation such as a pin arrangement vertically moving to contact skin, a spray force or suction force of air through a jet orifice or a suction opening, a touch to the skin, a contact of an electrode, electrostatic force, 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 can also 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 direct contact. Two or more haptic modules 153 may be provided according to the particular configuration of the mobile terminal 100.
An optical output module 154 can 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 message reception, call signal reception, a missed call, an alarm, a schedule alarm, an email reception, 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 that a user has checked the generated event, for example.
The interface unit 160 serves as an interface for external devices to be connected with the mobile terminal 100. For example, the interface unit 160 can receive data transmitted from an external device, receive power to transfer to elements and components within the mobile terminal 100, or transmit internal data of the mobile terminal 100 to such external device. 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 (also referred to herein as an “identifying device”) may take the form of a smart card. Accordingly, the identifying device can 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 can serve as a passage to allow power from the cradle to be supplied to the mobile terminal 100 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 there through. 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 can store programs to support operations of the controller 180 and 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 one or more types of storage mediums including a flash memory type, a hard disk type, a solid state disk (SSD) type, a silicon disk drive (SDD) type, 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, an optical disk, and the like. The mobile terminal 100 may also be operated in relation to a network storage device that performs the storage function of the memory 170 over a network, such as the Internet.
The controller 180 may typically control the general operations of the mobile terminal 100 as well as operations associated with the application programs. 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 can also perform the 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 can control one or a combination of those components in order to implement various exemplary embodiments disclosed herein.
The power supply unit 190 receives external power or provide internal power and supply the appropriate power required for operating respective elements and components included in the mobile terminal 100. The power supply unit 190 may include a battery, which is typically 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 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. In this example, the power supply unit 190 can 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 medium, a machine-readable medium, or similar medium using, for example, software, hardware, or any combination thereof.
Referring now to FIGS. 1B and 1C, the mobile terminal 100 is described with reference to a bar-type terminal body. However, the mobile terminal 100 may alternatively be implemented in any of a variety of different configurations. Examples of such configurations include watch-type, clip-type, glasses-type, or as a folder-type, flip-type, slide-type, swing-type, and swivel-type in which two and more bodies are combined with each other in a relatively movable manner, and combinations thereof. Discussion herein will often relate to a particular type of mobile terminal (for example, bar-type, watch-type, glasses-type, and the like). However, such teachings with regard to a particular type of mobile terminal will generally apply to other types of mobile terminals as well.
Here, considering the mobile terminal 100 as at least one set, the terminal body may be understood as a conception referring to the set.
The mobile terminal 100 will generally include a case (for example, frame, housing, cover, and the like) forming the appearance of the terminal. In this embodiment, the case is formed using a front case 101 and a rear case 102. Various electronic components are incorporated into a space formed between the front case 101 and the rear case 102. At least one middle case may be additionally positioned between the front case 101 and the rear case 102.
The display unit 151 is shown located on the front side of the terminal body to output information. As illustrated, a window 151a of the display unit 151 may be mounted to the front case 101 to form the front surface of the terminal body together with the front case 101.
In some embodiments, electronic components may also be mounted to the rear case 102. Examples of such electronic components include a detachable battery 191, an identification module, a memory card, and the like. Rear cover 103 is shown covering the electronic components, and this cover 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 are externally exposed.
As illustrated, when the rear cover 103 is coupled to the rear case 102, a side surface of the rear case 102 is partially exposed. In some cases, upon the coupling, the rear case 102 may also be completely shielded by the rear cover 103. In some embodiments, 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), aluminum (Al), titanium (Ti), or the like.
As an alternative to the example in which the plurality of cases form an inner space for accommodating 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 is formed in such a manner that synthetic resin or metal extends from a side surface to a rear surface.
If desired, the mobile terminal 100 may include a waterproofing unit (not shown) for preventing 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 module 152a and 152b, a proximity sensor 141, an illumination sensor 142, 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, as illustrated in FIGS. 1B and 1C, description will be given of the exemplary mobile terminal 100 in which the front surface of the terminal body is shown having 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, the side surface of the terminal body is shown having the second manipulation unit 123b, the microphone 122, and the interface unit 160, and the rear surface of the terminal body is shown having the second audio output module 152b and the second camera 121b. 
However, those components may not be limited to the arrangement. Some components may be omitted or rearranged or located on different surfaces. For example, the first manipulation unit 123a may be located on another surface of the terminal body, and the second audio output module 152b may be located on the side surface of the terminal body other than the rear surface of the terminal body.
The display unit 151 outputs information processed in the mobile terminal 100. For example, the display unit 151 may display execution screen information of an application program executing at 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 be implemented using one or more suitable display devices. Examples of such suitable display devices include 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, an e-ink display, and combinations thereof.
The display unit 151 may be implemented using two display devices, which can implement the same or different display technology. For instance, a plurality of the display units 151 may be arranged on one side, either spaced apart from each other, or these devices may be integrated, or these devices may be arranged on different surfaces.
The display unit 151 may also include a touch sensor which senses a touch input received at the display unit. When a touch is input to the display unit 151, the touch sensor may be configured to sense this touch and the controller 180, for example, may generate a control command or other signal 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 a film having a touch pattern, disposed between the window 151a and a display on a rear surface of the window 151a, or a metal wire which is patterned directly on the rear surface of the window 151a. Alternatively, 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 also form a touch screen together with the touch sensor. Here, the touch screen may serve as the user input unit 123 (see FIG. 1A). Therefore, the touch screen may replace at least some of the functions of the first manipulation unit 123a. 
The first audio output module 152a may be implemented in the form of a receiver for transferring call sounds to a user's ear and the second audio output module 152b may be implemented in the form of a loud speaker to output alarm sounds, multimedia audio reproduction, and the like.
The window 151a of the display unit 151 will typically include an aperture to permit audio generated by the first audio output module 152a to pass. One alternative is to allow audio to be 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 is otherwise hidden in terms of appearance, thereby further simplifying the appearance and manufacturing of the mobile terminal 100.
The optical output module 154 can be configured to output light for indicating an event generation. Examples of such events include a message reception, a call signal reception, a missed call, an alarm, a schedule alarm, an email reception, information reception through an application, and the like. When a user has checked a generated event, the controller 180 can control the optical output module 154 to stop the light output.
The first camera 121a can process image frames such as still or moving images obtained by the image sensor in a capture mode or a video call mode. The processed image frames can then 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 provide input to 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 tactile method that allows the user to perform manipulation such as touch, push, scroll, or the like. The first and second manipulation units 123a and 123b may also employ any non-tactile method that allows the user to perform manipulation such as proximity touch, hovering, or the like.
FIG. 1B illustrates the first manipulation unit 123a as a touch key, but possible alternatives include a mechanical key, a push key, a touch key, and combinations thereof.
Input received at the first and second manipulation units 123a and 123b may be used in various ways. For example, the first manipulation unit 123a may be used by the user to provide an input to a menu, home key, cancel, search, or the like, and the second manipulation unit 123b may be used by the user to provide an input to control a volume level being output from the first or second audio output modules 152a or 152b, to switch to a touch recognition mode of the display unit 151, or the like.
As another example of the user input unit 123, a rear input unit (not shown) may be located on the rear surface of the terminal body. The rear input unit can be manipulated by a user to provide input to the mobile terminal 100. The input may be used in a variety of different ways. For example, the rear input unit may be used by the user to provide an input for power on/off, start, end, scroll, control volume level being output from the first or second audio output modules 152a or 152b, switch to a touch recognition mode of the display unit 151, and the like. The rear input unit may be configured to permit touch input, a push input, or combinations thereof.
The rear input unit may be located to overlap the display unit 151 of the front side in a thickness direction of the terminal body. As one example, the rear input unit may be located on an upper end portion of the rear side 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. Alternatively, the rear input unit can be positioned at most any location of the rear side of the terminal body.
Embodiments that include the rear input unit may implement some or all of the functionality of the first manipulation unit 123a in the rear input unit. As such, in situations where the first manipulation unit 123a is omitted from the front side due to the touch screen or rear input unit replacing at least some functions of the first manipulation unit 123a provided on the front of the terminal body, the display unit 151 can have a larger screen.
As a further alternative, the mobile terminal 100 may include a finger scan sensor which scans a user's fingerprint. The controller 180 can then use fingerprint information sensed by the finger scan sensor as part of an authentication procedure. The finger scan sensor may also be installed in the display unit 151 or implemented in the user input unit 123.
The microphone 122 is shown located at an end of the mobile terminal 100, but other locations are possible. If desired, multiple microphones may be implemented, with such an arrangement permitting the receiving of stereo sounds.
The interface unit 160 may serve as a path allowing the mobile terminal 100 to interface with external devices. For example, the interface unit 160 may include one or more 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 is shown located at the rear side of the terminal body and includes an image capturing direction that is substantially opposite to the image capturing direction of the first camera unit 121a. 
The second camera 121b can 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 an array camera, images may be captured in various manners using the plurality of lenses and images with better qualities.
A flash 124 is shown 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 can be located on the terminal body. The second audio output module 152b may implement stereophonic sound functions in conjunction with the first audio output module 152a, and may be also used for implementing a speaker phone mode for call communication.
At least one antenna for wireless communication may be located on the terminal body. The antenna may be installed in the terminal body or formed by the case. For example, an antenna which configures a part of the broadcast receiving module 111 may be retractable into the terminal body. Alternatively, an antenna may be formed using a film attached to an inner surface of the rear cover 103, or a case that includes a conductive material.
A power supply unit 190 for supplying power to the mobile terminal 100 may include a battery 191, which is mounted in the terminal body or detachably coupled to an outside of the terminal body.
The battery 191 may receive power via a power source cable connected to the interface unit 160. Also, the battery 191 can be recharged in a wireless manner using a wireless charger. Wireless charging may be implemented by magnetic induction or electromagnetic resonance.
The rear cover 103 is shown coupled to the rear case 102 for shielding the battery 191, to prevent separation of the battery 191, and to protect the battery 191 from an external impact or from foreign material. 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 can also be provided on the mobile terminal 100. As one example of an 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 is a touch pen for assisting or extending a touch input to a touch screen.
Hereinafter, description will be given of exemplary embodiments associated with a control method which can be implemented in the mobile terminal having such configuration, with reference to the accompanying drawings. It will be obvious to those skilled in the art that the present disclosure can be specified into other particular forms without departing from the spirit and essential characteristics of the present disclosure.
FIG. 2 is a conceptual view illustrating operations implemented according to the present invention.
As illustrated in FIG. 2, a display unit 251 is provided with a first region A located on a front surface of a terminal main body, and a second region B extending from the first region A and located on side surfaces of the main body. The first region A and the second region B differ from each other in a type of information displayed. The first region A and the second region B are divided according to different types of user graphic interfaces (GUIs) provided thereto, respectively.
Also, the second region B is provided with a left-sided region B1 and a right-sided region B2 located at left and right side surfaces of the terminal, respectively. The second region B has a left-right symmetric structure based on the first region A.
Referring to FIG. 2A, a home screen page may be output on the display unit 251 of the mobile terminal. The home screen page may include at least one object. The object may be an icon of an application installed in the mobile terminal or a widget. Here, the home screen page may be output over the first and second regions A and B, but the present invention may not be limited to this. For example, the home screen page may be output only on the first region A, and the second region may be a target area to which a touch input is applied without an output of information.
Referring to FIG. 2B, the controller senses a touch input when the touch input is applied to the second region B, and executes a control operation associated with the touch input. In this example, when a touch input is applied to a notification icon I notifying an event generation, information related to the event is output on the first region A.
Such operations associated with the touch onto the side surfaces should be supported by hardware. Hereinafter, the hardware configuration of the terminal performing the operations of FIG. 2 will be described in more detail. The present invention also provides a structure of implementing the operations in hardware as well as implementing a larger screen by reducing a size of bezel.
FIG. 3A is a front perspective view illustrating one example of a mobile terminal in accordance with the present invention, and FIG. 3B is a rear perspective view of the mobile terminal illustrated in FIG. 3A.
A mobile terminal 200 is described with reference to a bar-type terminal body. However, the mobile terminal 200 may alternatively be implemented in any of a variety of different configurations. Examples of such configurations include slide-type, folder-type, swing-type, and swivel-type in which two and more bodies are combined with each other in a relatively movable manner, and combinations thereof.
The mobile terminal 200 generally includes a case (for example, frame, housing, cover, and the like) forming the appearance of the terminal. In this embodiment, the case may be divided into a front case 201 and a rear case 202 (see FIGS. 3A and 3B). Various electronic components are incorporated into a space formed between the front case 201 and the rear case 202. At least one middle case may be additionally positioned between the front case 201 and the rear case 202.
The terminal body, generally the front case 201 is shown having a display unit 251, an audio output module 252, a camera module 221 and the like. An interface 270 and the like may be disposed on side surfaces of the front case 201 and the rear case 202.
The display unit 251 occupies most of a main surface of the front case 201. That is, the display unit 251 is disposed on the front surface of the terminal to display visual information. The display unit 251 disclosed herein is configured in the form of extending up to another surface of the terminal in addition to the front surface of the terminal. In more detail, the display unit 251 is provided with a first region A located on the front surface, and a second region B (see FIG. 2) extending from the first region A and located on the side surfaces of the main body.
For example, a window which is disposed on an upper surface of the display unit 251 is configured in a manner that both side surfaces thereof are curved. Accordingly, the appearance of the front surface and the side surface of the terminal body is defined by the window. Therefore, the first region 261 and the second region 262 may be connected without a physical boundary therebetween. Here, the display unit 251 may be provided with a display device which is formed in a curved shape and embedded to correspond to the window.
As another example, the display unit 251 may be a flexible display. The flexible display refers to a display which is curved, bent, twisted, folded, or rolled by an external force. Here, the flexible display unit may include both a general flexible display and an electronic paper.
The typical flexible display is generally formed as a lightweight, non-fragile display, which still exhibits characteristics of a conventional flat panel display, but is instead fabricated on a thin flexible substrate which can be curved, bent, folded, or rolled, like a paper.
The term e-paper refers to a display technology employing the characteristic of a general ink, and is different from the conventional flat panel display in view of using reflected light. E-paper is generally understood as changing pictures or text using a twist ball or via electrophoresis using a capsule.
According to the characteristic of the flexible material, a terminal main body in which both side surfaces of the display unit are curved may be configured.
The audio output module 252 and the camera module 221 may be disposed on a region adjacent to one of both end portions of the display unit 251, and a front input unit (not illustrated) and a microphone 222 may be disposed on a region adjacent to the other end portion.
The front input unit is an example of a user input unit 230 (see FIG. 1), which may include a plurality of manipulation units. The manipulation units may be referred to as a manipulating portion, and may employ any tactile method that allows the user to perform manipulation with applying a tactile feeling.
Also, the display unit 251 may form a touch screen along with a touch sensor, and in this case, the touch screen may be a user input unit. This may allow for employing a configuration without a front input unit on the front surface of the terminal. That is, the first region 252 may be the only one input unit located on the front surface of the terminal.
Referring to FIG. 3B, the rear surface of the terminal body, namely, the rear case 202 may be further provided with a camera module 221′. The camera module 221′ may have an image capturing direction that is substantially opposite to the image capturing direction of the camera module 221 (see FIG. 3A), and have different pixels from the camera module 221.
For example, the camera module 221 has a smaller number of pixels to capture an image of the user's face and transmits such image to another party, and the camera module 221′ has a larger number of pixels to capture an image of a general object and not immediately transmits it in most cases. The first and the second camera modules 221 and 221′ may be installed on the terminal body such that they can be rotatable or popped up.
A flash and a mirror may be additionally disposed adjacent to the camera module 221′. When an image of a subject is captured with the camera module 221′, the flash may illuminate the subject. The mirror may allow the user to see himself or herself when he or she wants to capture his or her own image (i.e., self-image capturing) by using the camera module 221′.
An audio output unit (not illustrated) may be further disposed on the rear surface of the terminal body. The rear audio output module may implement stereophonic sound functions in conjunction with the front audio output module 252 (refer to FIG. 3A), and may be also used for implementing a speaker phone mode for call communication.
That is, the front audio output module 252 (first audio output module) configured as a receiver may be located on the front surface of the terminal, and the second audio output module configured as a speaker may be located on the rear surface. However, the present disclosure may not be limited to this, and the second audio output module may be provided on the side surface of the terminal.
The terminal body is provided with a power supply unit for supplying power to the mobile terminal 200. The power supply unit 290 may be embedded in the terminal body or detachably coupled to an outside of the terminal body.
As illustrated, a rear input unit 232 may be disposed on the rear surface of the terminal body. The rear input unit 232, for example, may be located below the camera module 221′.
The rear input unit 232 can be manipulated by a user to provide input of a command for controlling an operation of the mobile terminal 200. The input may be used in a variety of different ways. For example, the rear input unit 232 may be manipulated by the user to input commands such as power on/off, start, end, scroll, and command such as a control of a volume level output from the audio output module 252, switching of a touch recognition mode of the display unit 251, and the like. The present disclosure, however, may not be limited to this, and the terminal may include one or both of the front input unit and the rear input unit 232.
FIG. 4 is a partial sectional view of a mobile terminal having a display module. As illustrated in FIG. 4, a display 330, a touch sensor 320 and a window 310 are provided on a frame 340. The frame, 340, the display 330, the touch sensor 320 and the window 310 may all be curved toward side surfaces of the main body. Here, a bezel by the display 330 of the mobile terminal is as thin as corresponding approximately to a thickness of the window 310.
The bezel may have the least size when the window 310 is curved (bent) by 90°, in case where the window 310 is curved with a radius of curvature R at a point 0 located within the terminal. However, there is a case where the window 310 fails to be curved by 90° due to a process problem. That is, there is a case where an angle α illustrated in FIG. 4 is smaller than 90°.
For example, when curved by 90°, the window 310 is likely to be broken. As such, if the window 310 fails to be curved by 90°, the window 310 should first be curved as much as possible and then the rest portion, namely, a portion corresponding to D in FIG. 4 should be formed by using another member, other than the window 310. Even in this instance, glass may also be used but there is still a problem that the glass has to be bonded to the window 310. Therefore, one embodiment disclosed herein will be given limitedly of an example using another member, other than the glass. Here, the portion D may correspond to a side bezel where any image is not displayed when the mobile terminal is viewed in a lateral direction, but the side bezel has no relationship to a bezel when the mobile terminal is viewed in a front direction. So, detailed description will be omitted.
FIG. 5 is an exploded perspective view of a mobile terminal 300 in accordance with a first exemplary embodiment disclosed herein, FIG. 6 is a partially-exploded perspective view of FIG. 5, and FIG. 7 is a sectional view taken along the lines AA, BB and CC of FIG. 5. Hereinafter, the first exemplary embodiment disclosed herein will be described with reference to FIGS. 5 to 7.
A mobile terminal 300 in accordance with a first exemplary embodiment disclosed herein may include a main body having front and side surfaces, a window 310 disposed on a top of the main body and curved (or bent) from the front surface to one point of each side surface so as to define at least part of each side surface, a touch sensor 320 disposed on a rear surface of the window 310 and curved along the shape of the window 310, a display 330 disposed on a rear surface of the touch sensor 320 and curved along the shape of the touch sensor 320, a frame 340 disposed on a rear surface of the display 330 and having a shape corresponding to the display 330 to support the display 330, and supporters to support ends of the window 310, the touch sensor 320 and the display 330. Also, a rear surface of the main body is covered with a rear case 380.
Here, the touch sensor 320 and the display 330, as illustrated in FIG. 7, are longer or wider than the window 310 by an externally-exposed region thereof. That is, the touch sensor 320 and the display 330 are formed longer than the window 310 by the portion D, as illustrated in a supporting member 370 of FIG. 4.
The above structure is similarly employed in second to fourth exemplary embodiments to be explained later. Specifically, the touch sensor 320 and the display unit 330 are formed longer than the window 310, such that a region longer than the display 310 can be externally exposed before the touch sensor 320 and the display 330 are coupled. Here, the window 310 which is shorter than the touch sensor 320 and the display 330 is supported by the supporter so as to be stably coupled.
The frame 340 according to the first exemplary embodiment disclosed herein, as illustrated in FIG. 6, includes a front surface portion 341 facing the front surface and forming a flat or curved surface, and side surface portions 342 each extending from the front surface portion 341 and curved toward the side surface of the main body. The side surface portion 342 may be formed to be almost perpendicular to the front surface portion 341, and a curved section of the side surface portion 342, unlike the window 310, can exceed 90°.
Here, the touch sensor 320 and the display 330 are curved to correspond to a curved shape of the window 310. When the front surface portion 341 of the frame 340 is curved, the display 330, the touch sensor 320 and the window 310 are curved accordingly. A printed circuit board 350 is disposed below the frame 340 to perform a function of the controller 180.
The first exemplary embodiment includes the supporting members 370 for supporting the window 310. The supporting members 370 also support the touch sensor 320 and the display 330 as well as the window 310, and are located between the frame 340 and the rear case 380. Each of the supporting members 370 includes a vertical portion 371 that is located below the window 310 to come in contact with a lower end portion of the window 310 for support, and a horizontal portion 372 which is formed perpendicular to the vertical portion 371 to support the touch sensor 320 and the display 330. The horizontal portion 372 may be provided with a plurality of through holes 373 which face a top. Each of the through holes 373 is configured such that both of a first protrusion 343 protruding from a lower end of the frame 340 and a second protrusion 381 protruding from an edge of the upper surface of the rear case 380 are inserted therein.
In such a manner, the frame 340 and the rear case 380 may be engaged with the supporting members 370 in a manner that the first protrusion 343 and the second protrusion 381 are simultaneously inserted into one through hole 373 and are fixed in a closely-adhered state. FIG. 7B illustrates that the first protrusion 343 is formed more outside and the second protrusion 381 is formed more inside, but the present invention may not be limited to this. The first protrusion 343 may also be formed more inside.
FIG. 7A illustrates that the vertical portion 371 of the supporting member 370 comes in contact with the window 310, and the touch sensor 320, the display unit 330 and the frame 340 are mounted on the horizontal portion 372. FIG. 7B illustrates that the first protrusion 343 formed on the lower end of the frame 340 and the second protrusion 381 protruding from the upper surface of the rear case 380 are inserted into the through hole 373. The first protrusion 343 is formed to have the same height as the through hole 373 formed at the horizontal portion 372.
Here, the supporting member 370 partially defines the appearance of the mobile terminal 300. Thus, the supporting member 370 may have a smoothly curved surface from a portion contacting the window 310 to a portion contacting the rear case 380. That is, that the vertical portion 371 and the horizontal portion 372 are perpendicular to each other merely indicates that portions thereof forming a space for mounting the touch sensor 320, the display 330 and the frame 340 are approximately perpendicular to each other, but does not indicate that the entire supporting member 370 is exactly formed in the perpendicular shape.
Here, a portion which is formed longer than the display 330 in FIG. 7B corresponds to the first protrusion 343. Also, a battery 390 is disposed beneath the rear case 380 to cover the rear surface of the main body. This will be equally applied to battery covers 490 and 590 according to the second and third exemplary embodiments to be explained later.
Here, the window 310, the touch sensor 320 and the display 330 may be integrally formed into a single display module 301.
FIG. 8 is an exploded perspective view of a mobile terminal 400 in accordance with a second exemplary embodiment disclosed herein, FIG. 9 is a partially-exploded perspective view of FIG. 8, and FIG. 10 is a sectional view taken along the lines AA, BB and CC of FIG. 8. Hereinafter, the second exemplary embodiment disclosed herein will be described with reference to FIGS. 8 to 10. Repetitive description of the same/like configurations to the first exemplary embodiment will be omitted.
As illustrated in FIGS. 8 to 10, a window 410, a touch sensor 420 and a display 430, similar to the first embodiment, are curved at side surfaces of the terminal. This is also similar to a frame 440. That is, the display 430, the touch sensor 420 and the window 410 disposed on the frame 440 are curved toward the side surfaces in a corresponding shape, similar to the first embodiment. Also, the window 410, the touch sensor 420 and the display 430 may be integrally formed into a single display module 401.
Here, the first exemplary embodiment has illustrated that the supporting members 370 support the touch sensor 320, the display 330 and the frame 340 as well as the window 310. However, the second exemplary embodiment employs mold members 415, instead of the supporting members 370. The mold members 415 may be formed on lower ends of the window 410 in a lengthwise direction of the mobile terminal 400 through an insert-injection molding operation. As illustrated in FIGS. 10A and 10B, the mold member 415 is as high as a portion at which the window 410 is formed shorter than the display 430.
In the second exemplary embodiment, the mold member 415 may correspond to the vertical portion 371 of the supporting member 370 of the first exemplary embodiment. However, in the second exemplary embodiment, a portion corresponding to the horizontal portion 372 of the supporting member 370 is formed by the frame 440. More specifically, as illustrated in FIG. 9, the frame 440 includes a front surface portion 441 that faces a front surface of the main body and is formed in a flat or curved shape, and a side surface portion 442 that extends from the front portion 441 and forms a curved surface curved toward the side surface of the mobile terminal 400.
In addition, in the second exemplary embodiment, the frame 440 further includes an edge portion 443 that protrudes from a lower end of the side surface portion 442 in a horizontal direction. The edge portion 443 is formed in a flat shape such that the mold member 415, the touch sensor 420 and the display 430 are flush with one another. However, the present invention may not be limited to this. As illustrated in a third exemplary embodiment to be explained later, a portion coming in contact with the mold member 415 may more protrude such that the touch sensor 420 and the display 430 can be fixedly inserted more stably.
As illustrated in FIGS. 10A and 10B, the mold member 415, the touch sensor 420 and the display 430 are mounted on the edge portion 443. A third protrusion 481 protrudes from an edge of an upper surface of the rear case 480 and comes in contact with an inner side surface of the frame 440. That is, the third protrusion 481 closely comes in contact with an inner side of the side surface portion 442 of the frame 440, and thus the frame 440 is firmly fixed to a rear case 480.
In the second exemplary embodiment, the mold member 415 may be modularized with the window 410 at the side end of the window 410 through the insert-injection molding operation. In addition, the window 410, the mold member 415, the touch sensor 420 and the display 430 may be integrated into a single module. Here, a printed circuit board 450, as similar to the first exemplary embodiment, is located between the frame 440 and the rear case 480.
Here, the frame 440 may extend down to a lower end portion of the side surface of the main body, and the rear surface of the frame 440 may be covered with the rear case 480 and the battery cover 490.
FIG. 11 is an exploded perspective view of a mobile terminal 500 in accordance with a third exemplary embodiment disclosed herein, FIG. 9 is a partially-exploded perspective view of FIG. 11, and FIG. 13 is a sectional view taken along the lines AA and BB of FIG. 11. Hereinafter, the third exemplary embodiment disclosed herein will be explained with reference to FIGS. 11 to 13. Detailed description of the same/like configurations to the foregoing first and second exemplary embodiments will be omitted in the third exemplary embodiment.
The third exemplary embodiment is similar to the second exemplary embodiment in that a window 510, a touch sensor 520 and a display 530 are mounted on a frame 540, but different from the second exemplary embodiment in view of replacing the mold member 415 with a protruding portion 544 protruding from the frame 540. That is, a supporting member in the third exemplary embodiment, as illustrated in FIGS. 13A and 13B, are the very frame 540. More specifically, the frame 540 includes a front surface portion 541 that faces a front surface and has a flat or curved surface, and a side surface portion 542 that extends from the front portion 541 and faces a side surface. The frame 540 further includes a recess portion 543 that extends from the side surface portion 542 and is recessed toward a bottom, and a protruding portion 544 that extends from the recess portion 543 and protrudes toward a top. That is, the recess portion 543 and the protruding portion 544 perform the function of the supporting member 370 in the first exemplary embodiment. Here, the protruding portion 544 is externally exposed so as to define a part of the appearance of the mobile terminal 500.
Also, fourth protrusions 581 are formed at an edge of an upper surface of the rear case 580. Each of the fourth protrusions 581 is closely adhered onto an inner side of the side portion 542 of the frame 540 so as to more enhance firm fixing between the frame 540 and the rear case 580. The fourth protrusion 581 is formed approximately as high as the recess portion 543.
Here, a plurality of jig holes 545 are formed on the side portion 542, as illustrated in FIG. 12. The jig holes 545 are holes in which jigs (not illustrated) are partially inserted. The jigs facilitate the window 510, the touch sensor 520 and the display 530 to be mounted in the recess portion 543. For example, a bar may be inserted through the jig hole 545 from an inside of the jig hole 545 so as to be externally exposed. The window 510, the touch sensor 520 and the display 530 are then placed on the externally-exposed bar so as to be guided up to the recess portion 543.
The jig hole 545 is merely illustrated in the third exemplary embodiment, but the present invention is not limited to this. The first and second exemplary embodiments may similarly employ the jig hole 545 to facilitate the mounting of the window 510, the touch sensor 520 and the display 530.
In such a manner, the third exemplary embodiment has illustrated that the frame 540 which has already been used is changed in shape to define a space for mounting the window 510, the touch sensor 520 and the display 530 thereon and the protruding portion 544 comes in contact with the lower end of the window 510. A printed circuit board 550 is disposed between the frame 540 and the rear case 580. Here, the third exemplary embodiment is configured such that the frame 540 extends from the inside to outside of the main body to accommodate thereon the window 510, the touch sensor 520 and the display 530, without an additional member, thereby simplifying a fabrication process.

Hereinafter, the fourth exemplary embodiment disclosed herein will be described with reference to FIGS. 14 to 20.
Detailed description of the same/like configurations to the foregoing first to third exemplary embodiments will be omitted in the fourth exemplary embodiment.
A supporting member in the fourth exemplary embodiment is formed by extending a rear case 680. The third exemplary embodiment uses an existing frame 640, but the fourth exemplary embodiment uses the rear case 680.
FIG. 4 is a partial sectional view of a mobile terminal in accordance with one exemplary embodiment disclosed herein. As illustrated in FIG. 4, a mobile terminal in accordance with one exemplary embodiment disclosed herein may be configured to be thinner because a front case 101 and a rear case 380 are integrally formed with each other. That is, the aforementioned mobile terminal 100 is configured such that the display unit 151 is provided on the front case 101 and various electronic components are located in a space between the front case 101 and the rear case 102. However, in the one exemplary embodiment of the present invention, a window 310, a touch sensor 320 and a display 330 are provided on the rear case 380 and various electronic components are located between the rear case 380 and a battery cover 390.
Here, the frame 340, as illustrated in FIG. 4, includes a front surface portion 341 facing the front surface of the terminal (or the main body) and having a flat or curved surface, and side surface portions 341 each extending from the front surface portion 341 and curved toward the side surface of the terminal. The side surface portion 342 is formed to be almost perpendicular to the front surface portion 341, and a curved section of the side surface portion 342, unlike the window 310, can exceed 90°. For example, the front surface portion 341 may be formed in a curved shape, for example, formed to be convex toward the front surface of the terminal. FIG. 4 merely illustrates an example that the front surface portion 341 is formed in a flat shape.
FIG. 14 is a perspective view of a mobile terminal 600 in accordance with one exemplary embodiment disclosed herein, FIG. 15 is an exploded perspective view of FIG. 14, and FIG. 16 is partially-exploded perspective view of FIG. 15.
Hereinafter, one exemplary embodiment disclosed herein will be described with reference to FIGS. 14 to 16, and it is assumed that a widthwise direction of the mobile terminal 600 is an X-axial direction, a lengthwise direction is an Y-axial direction, and a thickness direction is a Z-axial direction.
A mobile terminal 600 in accordance with one exemplary embodiment disclosed herein may include a main body having front and side surfaces, a window 610 curved (or bent) from the front surface to one point of each side surface so as to define at least a part of each side surface, a touch sensor 620 disposed on a rear surface of the window 610 and curved along the shape of the window 610, a display 630 disposed on a rear surface of the touch sensor 620 and curved along the shape of the touch sensor 620, a frame 640 disposed on a rear surface of the display 630 and having a shape corresponding to the display 630 to support the display 630, and a rear case 680 covering a rear surface of the main body.
The rear case 680 includes supporting members 370 to support ends of the window 610, the touch sensor 620, and the display 630.
Here, since the touch sensor 620 and the display 630 are formed longer than the window 610 toward the side surfaces of the main body, the supporting members 370 are components for supporting the window 610 while coming in contact with the window 610.
The touch sensor 620 and the display 630, as illustrated in FIGS. 16 to 20, are longer or wider than the window 610 by an externally-exposed region thereof. That is, as illustrated in relation to the supporting member 370 of FIG. 4, the touch sensor 620 and the display 630 are formed longer than the window 610 by the portion D.
The supporting member 370 in the fourth exemplary embodiment disclosed herein is formed by extending from the rear case 680, namely, by using the already-used rear case 680.
FIG. 15 is an exploded perspective view of FIG. 14, and FIG. 20 is a sectional view taken along the line AA of FIG. 14. As illustrated in FIGS. 15 and 20, the rear case 680 includes an accommodating portion 685 that accommodates therein the touch sensor 620 and the display 630, and a sidewall portion 683 that upwardly extends from an end of the accommodating portion 685 to come in contact with the window 610. The accommodating portion 685 is more recessed than the other portion of the rear case 680 such that the touch sensor 620 and the display 630 can be easily accommodated therein. That is, the supporting member 370 corresponds to the same portion as the sidewall portion 683.
Meanwhile, referring to FIG. 15, the rear case 680 includes the sidewall portion 683 that is formed long in an Y-axial direction, a bottom surface portion 681 that extends from the sidewall portion 683 in an X-axial direction to be perpendicular to the sidewall portion 683 and is formed higher than the sidewall portion 683 in a Z-axial direction, and a curved surface portion 682 that is curved to connect the bottom surface portion 681 and the sidewall portion 683 to each other.
A decoration member 615 is further provided at one side of the window 610. The decoration member 615 has the same thickness as the window 610 and is mounted on the bottom surface portion 681 and the curved surface portion 682. The curved surface portion 682 should have a shape corresponding to an end portion of the decoration member 615.
The decoration member 615 includes a main surface portion 615a that is formed on a front surface thereof and occupies most of the front surface, and a curved portion 615b that extends from the main surface portion 615a and is curved to be mounted on the curved surface portion 682. That is, the decoration member 615 is a component for smoothly connecting the curved surface portion 682 and the window 610 to each other. The curved surface portion 682 and the curved portion 615b have the corresponding shapes so as to be engaged with each other.
Also, in the one exemplary embodiment, as illustrated in FIGS. 15 to 17, hooks 616 and 617 are utilized to fix the touch sensor 620 and the display 630.
For example, a first hook 616 is formed on the main surface portion 615a of the decoration member 615, and a first hole 646 is formed on the front surface portion 341 (see FIG. 4) of the frame 640. The first hook 616 is then fixedly inserted into the first hole 646, to tightly secure the touch sensor 620 and the display 630 between the decoration member 615 and the frame 640.
A second hook 617 is formed on the curved portion 615b of the decoration member 615, and a second hole 647 is formed on the side surface portion 342 (see FIG. 4) of the frame 640. The second hook 617 is fixedly inserted into the second hole 647, to prevent the curved portion 615b from being detached. That is, the first hook 616 is used for the purpose of preventing a movement of the decoration member 615 in the Z-axial direction, and the second hook 617 is used for the purpose of preventing the detachment of the decoration member 615 in the X-axial direction.
Also, those drawings illustrate that the decoration member 615 is located at a lower end of the mobile terminal 600, but may also be provided at an upper end of the mobile terminal, if necessary. Here, the decoration member 615 may be made of polycarbonate (PC), and generally used for shielding a lower bezel of the mobile terminal 600. A bezel in one exemplary embodiment refers to a region on which an image signal is not output of an entire region of the mobile terminal 600. The bezel is generally formed by a circuit (including a printed circuit board and a flexible printed circuit board) for driving the mobile terminal 600 or a case.
Meanwhile, FIG. 19A is a view of the mobile terminal 600, viewed in the Z-axial direction. The curved portion 615b of the decoration member 615 is formed with a curvature R1 on an XY plane. In one exemplary embodiment, the decoration member 615 is disposed on the lower bezel and has corner portions curved. That is, in the front view of the mobile terminal 600, as illustrated in FIG. 19A, four corners have a uniform radius R1. The one embodiment disclosed herein proposes a form that the decoration member 615 and the rear case 680 are coupled to each other.
Also, FIG. 19B is a view of the mobile terminal 600, viewed in the X-axial direction, and FIG. 19C is a view of the mobile terminal 600, viewed in the Y-axial direction. The decoration member 615 has a curvature R2 on an YZ plane, and a curvature R3 on a ZX plane. As such, the decoration member 615 is three-dimensionally formed with the predetermined curvatures.
The decoration member 615 with the curvatures, as illustrated in FIG. 16, is disposed on the touch sensor 620, and the printed circuit board 650 is disposed between the frame 640 and the rear case 680. Also, the rear case 680 also includes a wide and flat cover portion 684 that is formed at one side of the accommodating portion 685 to cover the rear surface of the main body.
FIGS. 18A and 18B are a lateral view and a sectional view of a part C of FIG. 14, respectively. As illustrated in FIGS. 18A and 18B, the touch sensor 620 and the display 630 are formed longer than the window 610 in a lengthwise direction (i.e., the Y-axial direction in FIG. 14) of the main body of the terminal.
As aforementioned, the decoration member 615 is curved with the predetermined curvatures R1, R2 and R3 on the XY, YZ and ZX planes. In order to mount the decoration member 615 with the three-dimensional curvatures on the rear case 680, cutout portions 625 and 635 (see FIG. 16) are formed at end portions of the touch sensor 620 and the display 630, respectively, in one exemplary embodiment disclosed herein. Each end portion with the cutout portion 625 and 635 of the touch sensor 620 and the display 630 corresponds to the curved portion 615b and a section from the curved portion 615b to one point of the main surface portion 615a. The cutout portions may also fully meet the purpose of the present invention as long as they are formed at side end portions of the touch sensor 620 and the display 630.
Since the curved portion 615b of the decoration member 615 has the three-dimensional curvatures along the X-axial, Y-axial and Z-axial directions, when the touch sensor 620 and the display 630 extend up to a region D2 illustrated in FIGS. 18A and 18B without the cutout portions 625 and 635, a starting point that the decoration member 615 is curved should be moved to the left side of a boundary between the window 610 and the decoration member 615 in FIGS. 18A and 18B, and accordingly the decoration member 615 should have a more increased width D1.
For example, as illustrated in FIG. 19A, the curved portion 615b should be inwardly curved with a predetermined curvature, starting from the boundary between the window 610 and the decoration member 615 within the XY plane. However, the curved portion 615b cannot be inwardly curved if the cutout portions 625 and 635 are not formed. That is, the cutout portions 625 and 635 may result in ensuring a space in which the curved portion 615b can be curved.
If the decoration member 615 increases in width, the lower bezel of the mobile terminal 600 increases in size. To prevent this in the one exemplary embodiment, as illustrated in FIG. 16, the cutout portions 625 and 635 are formed at the touch sensor 620 and the display 630. The formation of the cutout portions 625 and 635 may allow the curved portion 615b of the decoration member 615 to have the curvatures in the three-dimensional manner, without moving the starting point that the decoration member 615 is curved to the left side of the boundary between the window 610 and the decoration member 615 in FIGS. 18A and 18B. That is, the curved portion 615b of the decoration member 615 can be curved in the X-axial, Y-axial and Z-axial directions at the boundary between the window 610 and the decoration member 615. This may result in preventing an increase in the size of the lower bezel of the mobile terminal and simultaneously providing an attractive design.
The corner structure for reducing the lower bezel has been described, which will equally be applied to an upper bezel. That is, the decoration member 615 which is disposed on an upper end of the mobile terminal and mounted on the bottom surface portion 681 and the curved surface portion 682 may be formed. Here, the upper bezel, similar to the lower bezel, can be reduced in size.
Also, when the window 610 located on the top of the mobile terminal is configured to be curved with three-dimensional curvatures, similar to the curved portion 615b of the decoration member 615, and the cutout portions 625 and 635 are formed at the touch sensor 620 and the display 630, the upper bezel of the mobile terminal, similar to the aforementioned lower bezel, can be reduced in size.
In such a manner, according to one embodiment disclosed herein, the lower or upper bezel can be minimized in size. Here, since the decoration member 615 is a portion where image information cannot be output, the first manipulation unit 123a should be located within the region of the display 630.
Meanwhile, the cutout portions 625 and 635 may also be formed at at least a part of the region D2, or at least a part of a region D3.
Here, D1 refers to the width of the decoration member 615, and also corresponds to the size of the lower bezel of the mobile terminal 600. D2 refers to a region where the touch sensor 620 and the display 630 are formed longer than the window 610, and D3 refers to a stepped portion of the display 630, as illustrated in FIGS. 18A and 18B.
Here, when the cutout portions 625 and 635 are formed near the boundary between the decoration member 615 and the window 610, it is difficult to achieve the purpose for fixing the touch sensor 620 and the display 630 by the first hook 616. Therefore, the cutout portions 625 and 635 are preferably formed at a part of the region D3.
That is, the decoration member 615 should be located on the upper surface of the touch sensor 620.
As illustrated in FIG. 20, the rear case 680 includes a sidewall portion 683 that is brought into contact with a window 610, and an accommodating portion 685 that is formed at an inner side of the sidewall portion 683 and accommodates a touch sensor 620 and a display 630 therein. The accommodating portion 685 is more recessed than the other portion of the rear case 680 such that the touch sensor 620 and the display 630 can be easily accommodated therein. Meanwhile, referring to FIG. 16, the rear case 680 includes a bottom surface portion 681 that perpendicularly extends from the sidewall portion 683 and is higher than the sidewall portion 683, and a curved surface portion 682 that is curved to connect the bottom surface portion 681 and the sidewall portion 683 to each other.
Meanwhile, a decoration member 615 which has the same thickness as the window 610 is further provided at one side of the window 610, such that the bottom surface portion 681 and the curved surface portion 682 are mounted thereon. The decoration member 615 includes a main surface portion 615a that is formed on a front surface thereof and occupies most of the front surface, and a curved portion 615b that extends from the main surface portion 615a and is curved to be mounted on the curved surface portion 682. That is, the decoration member 615 is a configuration for smoothly connecting the curved surface portion 682 and the window 610 to each other. The curved surface portion 682 and the curved portion 615b may have the corresponding shapes so as to be engaged with each other.
Here, the decoration member 615, as illustrated in FIG. 16, is located on an upper portion of the touch sensor 620, and a printed circuit board 650 is disposed between the frame 640 and the rear case 680. Also, a cover portion 684 for covering a rear surface of the terminal main body is widely formed at one side of the accommodating portion 685.
Meanwhile, one embodiment of the present invention may have a problem in view of a connection of a flexible printed circuit board (FPCB) in case where side surfaces of a mobile terminal are curved.
FIG. 21 is a partial perspective view in case where a mobile terminal is curved along a lengthwise direction thereof. As illustrated in FIG. 21, a window 10, a touch sensor 20 and a display 30 may all be curved in a lengthwise direction (Y-direction) of the mobile terminal. Here, drive integrated circuit (IC) chips 21 and 31 of the touch sensor 20 and the display 30 are attached to lower ends of the touch sensor 20 and the display 30, respectively, and connected to a printed circuit board (not illustrated) by FPCBs 25 and 35, respectively.
In such a manner, when the mobile terminal is curved in the lengthwise direction, there is not a big problem in an arrangement space of the drive IC chips 21 and 31. However, as illustrated in FIG. 22, when the mobile terminal is curved in a widthwise direction (X-direction) of the mobile terminal, there is a problem that portions to which the driver IC chips 21 and 31 are attached cannot be curved. That is, if the window 10 is divided into a central region 10b and both side surfaces 10a and 10c, the window 10 may merely be curved at the both side surfaces 10a and 10c, failing to be curved at the central region 10b. 
However, as illustrated in FIG. 23, if the driver IC chips 21 and 31 and the FPCBs 25 and 35 are arranged on the side surface of the mobile terminal, the mobile terminal can be fully curved in the widthwise direction thereof.
The present invention, as illustrated in FIG. 23, relates to a mobile terminal which is capable of being curved partially or entirely in a widthwise direction thereof by arranging FPCBs on a side surface of the mobile terminal.
Hereinafter, a configuration therefor will be explained.
As aforementioned, FIG. 5 is the exploded perspective view of the mobile terminal 300 in accordance with the first exemplary embodiment disclosed herein, FIG. 6 is the partially-exploded perspective view of FIG. 5, and FIG. 7 is the sectional view taken along the lines AA, BB and CC of FIG. 5. Hereinafter, a fifth exemplary embodiment will be described with reference to FIGS. 5 to 7. That is, the fifth exemplary embodiment is related to the first exemplary embodiment.
First, a mobile terminal 300 according to the fifth exemplary embodiment includes a main body having front and side surfaces, a display module 301 disposed on a top of the main body and curved from the front surface to the side surfaces to define at least parts of the side surfaces, a frame 340 disposed on a rear surface of the display module 301 and having a shape corresponding to the display module 301 to support the display module 301, a rear case 380 covering a rear surface of the main body, a PCB 350 located between the frame 340 and the rear case 380, and an FPCB 360 having one end connected to a side surface of the display module 301 and the other end electrically connected to the PCB 350.
Here, the FPCB 360 may be connected to the PCB 350 in a manner of bypassing the frame 340 (see the fifth exemplary embodiment) or penetrating through the frame 340 (see a sixth exemplary embodiment).
Here, the frame 340 includes a front surface portion 341 facing the front surface of the mobile terminal and having a flat or curved surface, and a side surface portion 342 extending from the front surface portion 341 toward the side surface of the mobile terminal so as to define at least a part of the side surface. The side surface portion 342 is formed to be almost perpendicular to the front surface portion 341, and can have a curved section exceeding 90°, unlike the window 310. The shapes of the front surface portion 341 and the side surface portion 342 are also applied equally to the display module 301, and also to the sixth exemplary embodiment to be explained later.
Here, the touch sensor 320 and the display 330 are curved to correspond to the curved shape of the window 310. When the front surface portion 341 of the frame 340 is curved, the display 330, the touch sensor 320 and the window 310 are curved accordingly. The PCB 350 is located beneath the frame 340 so as to perform a function of the controller 180.
The window 310, 410 in one embodiment disclosed herein is implemented as a single window. The touch sensor 320, 420 is located between the window 310, 410 and the display 330, 430 to sense a touch input applied to the window 310, 410.
One embodiment disclosed herein may allow for an integral structure of the display 330 disposed on the upper surface of the frame 340 and curved from the front surface toward the side surface, the touch sensor 320 disposed on the upper surface of the display 330 and curved along the shape of the display 330 to form at least the part of the side surface, and the window 310 disposed on the upper surface of the touch sensor 320 to form the appearance of the mobile terminal. That is, the display 330, the touch sensor 320 and the window 310 may be the components of the display module 301. This is equally applied to the sixth exemplary embodiment to be explained later.
As illustrated in FIG. 5, the supporting members 370 are disposed at both sides in the lengthwise direction of the mobile terminal 300 between the frame 340 and the rear case 380, to support lower portions of the display module 301 and the side surface portions 342 of the frame 340. Each of the supporting members 370 includes a vertical portion 371 that connects the window 310 and the rear case 380 so as to define at least a part of the appearance of the mobile terminal 300, and comes in contact with the window 310, and a horizontal portion 372 that accommodates thereon the touch sensor 320, the display 330 and the frame 340.
Here, since each supporting member 370 defines the part of the appearance of the mobile terminal 300, the supporting member 370 may have a smoothly curved surface from a portion contacting the window 310 to portion contacting the rear case 380. That is, that the vertical portion 371 and the horizontal portion 372 are perpendicular to each other merely indicates that portions thereof forming a space for mounting the touch sensor 320, the display 330 and the frame 340 are approximately perpendicular to each other, but does not indicate that the entire supporting member 370 is exactly formed in the perpendicular shape.
An accommodation groove 375 in which the FPCB 360 is mounted is formed along the vertical portion 371 and the horizontal portion 372. The accommodation groove 375, as illustrated in FIGS. 6A and 6B, includes a first part 375a recessed into the vertical portion 371, and a second part 375b formed perpendicular to the first part 375a and recessed into the horizontal portion 372. Here, a sidewall 375c which protrudes from the second part 375b and has a step corresponding to a height of the horizontal portion 372 is formed.
Meanwhile, the FPCB 360 includes a first vertical portion 360a that is accommodated in the first part 375a and connected to an end of the display module 301, a first horizontal portion 360b that perpendicularly extends from the first vertical portion 360a and is accommodated in the second part 375b, a second vertical portion 360c that extends from the first horizontal portion 360b and is upwardly formed along the sidewall 375c, and a second horizontal portion 360d that extends from the second vertical portion 360c over the accommodating groove 375 so as to be connected to the PCB 350. Here, the FPCB 360 includes a first FPCB 361 that is connected to the touch sensor 320 and the PCB 350 to realize a touch function, and a second FPCB 362 that is connected to the display 330 and the PCB 350 to represent image information. The first FPCB 361 and the second FPCB 362 have the same shape and overlap each other.
Lower end portions of the frame 340, the touch sensor 320 and the display 330 are placed on the first horizontal portion 360b. That is, when the display module 301 and the frame 340 are coupled to the supporting member 370, the FPCB 360 is pressed. Here, the FPCB 360 and the PCB 350 may be connected to each other by a connector 365 (see FIG. 7C).
Meanwhile, the horizontal portion 372 is provided with a first through hole 373, in which a first protrusion 343 formed on an edge of the lower end of the frame 340 and a second protrusion 381 protruding from an edge of an upper surface of the rear case 380 are inserted. Referring to FIG. 7B, it can be understood that the first through hole 373 is formed in plural through the horizontal portion 372 of the supporting member 370, and both of the first protrusion 343 protruding from the lower end of the frame 340 and the second protrusion 381 protruding from the upper surface of the rear case 380 are simultaneously inserted into each first through hole 373.
In such a manner, the frame 340 and the rear case 380 are engaged with the supporting member 370 in the manner that both of the first protrusion 343 and the second protrusion 381 are simultaneously into the single through hole 373 in a closely-adhered state. FIG. 7B is a sectional view taken along the line BB of FIG. 5, which shows that the first protrusion 343 is formed more outside than the second protrusion 381. The first protrusion 343 is as high as the first through hole 373 formed through the horizontal portion 372.
FIG. 7C is a sectional view taken along the line CC of FIG. 5. The FPCB 360 is connected to ends of the touch sensor 320 and the display 330 to be mounted in the accommodation groove 375 formed at the supporting member 370, and connected to the PCB 350 by the connector 365.
Here, the window 310 is formed along the side surface of the mobile terminal to be shorter than the touch sensor 320 and the display 330. In this instance, the part shorter than the touch sensor 320 and the display 330 is supplemented by the supporting member 370. This may allow the touch sensor 320 and the display 330 to be stably mounted on the supporting member 370 together with the window 310.
Hereinafter, a mobile terminal 400 according to a sixth exemplary embodiment disclosed herein will be described. In the following variation or embodiment, the same/like reference numerals are given to the same/like components to the foregoing embodiments, and description thereof will be omitted. The sixth exemplary embodiment corresponds to the aforementioned second exemplary embodiment.
FIG. 8 is an exploded perspective view of a mobile terminal in accordance with another exemplary embodiment disclosed herein, FIG. 9 is a detailed-exploded perspective view of a part of FIG. 8, and FIG. 10 is a sectional view taken along the lines AA, BB and CC of FIG. 8. Hereinafter, description will be given with reference to FIGS. 8 to 10.
The fifth exemplary embodiment has illustrated that the shorter part of the window 310 is supplemented by the separate members, namely, the supporting members 370, but the sixth exemplary embodiment illustrates that the mold members 415 (i.e., glass-inserted molds) are formed at an end of the window 410 through an insert-injection molding operation. Each of the mold members 415 is formed along a lengthwise direction of the mobile terminal 400. The sixth exemplary embodiment is substantially similar or the same to the fifth exemplary embodiment, except for replacing the supporting member 370 with the mold member 415. Thus, detailed description of he similar configurations will be omitted.
In the sixth exemplary embodiment, a second through hole 445 is formed through a side surface portion 442 of a frame 440 to connect an FPCB 460 and a PCB 450 to each other. The FPCB 460 is electrically connected to the PCB 450 through the second through hole 445. An edge portion 443 protrudes from a lower end of the side surface portion 442 of the frame 440 in a horizontal direction. A third protrusion 481 is formed at an edge of an upper surface of a rear case 480 covering the frame 440 and brought into contact with an inner side of the side surface portion 442 of the frame 440.
That is, the frame 440 in the sixth exemplary embodiment, similar to the fifth exemplary embodiment, includes a front surface portion 441 that faces a front surface of the mobile terminal 400 and has a flat or curved surface, a side surface portion 442 that extends from the front surface portion 441 and is curved toward a side surface of the mobile terminal 400, and an edge portion 443 that outwardly protrudes from the side surface portion 442 in a horizontal direction so as to define a mounting space of the display module 301.
FIG. 10A is a sectional view taken along the line AA of FIG. 8. As illustrated in FIG. 10A, side end portions of the mold member 415, the touch sensor 420 and the display 430 are mounted on the edge portion 443, and the third protrusion 481 allows the frame 440 to be more firmly coupled to the rear case 480. FIG. 10B is a sectional view taken along the line BB of FIG. 8. It can be seen more obviously in FIG. 10B that the mold member 415, the touch sensor 420 and the display 430 are mounted on the edge portion 443 at a portion without the third protrusion 481 formed. FIG. 10C is a sectional view taken along the line CC of FIG. 10. As illustrated in FIG. 10C, the FPCB 460 is connected to ends of the touch sensor 420 and the display 430, and connected to the PCB 450 by a connector 465 through the second through hole 445 formed at the frame 440.
Here, a width of the edge portion 443 is the same as that of a display module 401.
The window 310, 410, the touch sensor 320, 420, the display 330, 430 and the frame 340, 440 may be integrated together so as to be configured as one display module 301, 401.
