The A/V input unit 120 is for inputting an audio signal or a video signal, and may include a camera 121 and a microphone 122. The camera 121 processes a still image or image frames of a video obtained by an image sensor in a video call mode or a capturing mode. The processed image frames may be displayed on the display unit 151.
The microphone 122 receives external sound signals in a call mode, a recording mode, or a speech recognition mode and processes the sound signals to an electrical speech data. The processed speech data may be converted into a transmittable form and output to a mobile communication base station through the mobile communication module 112. Various noise removal algorithms may be implemented in the microphone 122, wherein the noise is generated in a process of receiving the external sound signals.
The user input unit 130 generates input data for allowing a user to control operations of the terminal. The user input unit 130 may be configured with a key pad, a dome switch, a touch pad (static pressure/static electricity), a jog wheel, a jog switch, etc. The user input unit 130 may include a hard key 131, such as a home key or a side key, etc.
The sensing unit 140 senses a current state of the terminal body 100, such as a position of the terminal body 100, whether there is a user contact, orientation of the mobile terminal, or acceleration/deceleration of the mobile terminal, and generates a sensing signal for controlling operations of the terminal body 100.

In addition, as a proximity sensor except a magnetic proximity sensor like the hall sensor, an optical proximity sensor, a capacitive proximity sensor, an Eddy current proximity sensor, an ultrasonic proximity sensor, or an inductive proximity sensor may also be used.
Furthermore, the sensing unit 140 may sense an On/Off state of the display unit 151 to be described later, and also sense whether the power is provided by the power supply unit 190, or whether an external device is combined with the interface unit 170.
In addition, the sensing unit 140 may sense whether the terminal case 200 to be described later is detached and the terminal case 200 is open.
The output unit 150 is for generating an output related to vision, sense of hearing, or sense of touch, and may include the display unit 151, a sound output module 152, an alarm unit 153, and a haptic module 154.
The display unit 151 displays information processed in the terminal body 100. For example, when the terminal body 100 is in a call mode, a user interface (UI) or graphic user interface (GUI) related to a call is displayed. When the terminal body 100 is in a video call mode or a capturing mode, a captured or/and received image, or a UI or a GUI is displayed.
Some displays among them may be configured with a transparent type or light-transmissive type for seeing the outside therethrough. This may be referred to as a transparent display, and a representative example of the transparent display is a transparent OLED (TOLED). A rear structure of the display unit 151 may also be configured with a light-transmissive structure. Due to this structure, a user may see objects positioned in the rear side of the terminal body through a region occupied by the display unit 151 of the terminal body.
There may be two or more display units 151 according to an implementation type of the terminal body 100. For example, a plurality of display units may be disposed separately or in an integrated type on one surface, or respectively on different sides of the terminal body 100.
When the display unit 151 and a sensor (hereinafter, referred to as a ‘touch sensor’) sensing a touch operation form a mutual layered structure (hereinafter, referred to as ‘touch screen’), the display unit 151 may also be used as an input device other than an output device. The touch sensor may have a form of, for example, a touch film, a touch sheet, or a touch pad.
The touch sensor may be configured to convert a pressure applied to a specific portion of the display unit 151 or a capacitance change occurring on a specific portion of the display unit 151 into an electrical input signal. The touch sensor may be configured to detect a pressure upon being touched as well as a touched position and area.
When there is a touch input on the touch sensor, a corresponding signal(s) is transmitted to a touch controller. The touch controller processes the signal(s) and transmits the processed signal(s) to the controller 180. Accordingly, the controller 180 may detect which region on the display unit 151 is touched.
The sound output module 152 may output audio data received from the wireless communication unit 110 in call reception, a call mode, a recording mode, a speech recognition mode, or a broadcast reception mode, or audio data stored in the memory 160. The sound output module 152 may also output a sound signal (for example, a call reception sound, or a message reception sound, etc.) related to a function performed in the mobile terminal 100. The sound output module 152 may include a receiver, a speaker, or a buzzer.
The alarm unit 153 may output a signal for notifying an event occurrence of the terminal body 100. As an example of an event occurred in the mobile terminal, there is call signal reception, message reception, a key signal input, or a touch input, etc. The alarm unit 153 may also output a signal for notifying an event occurrence with different types, for example, vibration, other than a video signal or an audio signal. Since the video signal or audio signal may be output through the display unit 151 or the sound output module 152, they 151 and 152 may be classified into a part of the alarm unit 153.
The haptic module 154 generates various effects of touch senses that a user may feel. A representative example of the touch sense effect generated by the haptic module 154 is vibration. The strength and pattern of vibration generated by the haptic module 154 are controllable. For example, different vibrations may be synthesized to be output or sequentially output.
The haptic module 154 may generate various touch sense effects, other than the vibration, such as effect of a pin array moving vertically with respect to contact skin surface, jet force or suction force of air through a jet orifice or an air inlet, graze for skin surface, a contact of an electrode, or stimulus of an electrostatic force, or an effect of reproduction of cold and warmth by using devices capable of heat absorption or generation.
The haptic module 154 may be implemented to allow a user to feel a touch sense effect through muscle sense of fingers or arms as well as to deliver the touch sense effect through a direct contact. Two or more haptic modules 154 may be prepared according to a configuration aspect of the mobile terminal 100.
The memory 160 may store a program for operation of the controller 180 and temporarily store input/output data (fro example, a phone book, messages, still images, videos). The memory 160 may store data related to vibrations and sounds of various patterns output during the touch input on the touch screen.
The memory 160 may include at least one type of recording medium of a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, an SD or XD memory, etc.), a random access memory (RAM), a static RAM (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, or an optical disc. The terminal body 100 may operate in relation to a web storage that performs a storage function of the memory 160 on the internet.
The interface unit 170 plays a role of passage with all external devices connected to the terminal body 100. The interface unit 170 receives data from the external devices, receives power and delivers the power to each element inside the terminal body 100, or allows data inside the terminal body 100 to be transmitted to the external devices.
The identification module is a chip storing various types of information for authenticating use authority of the terminal body 100, and may include a user identity module (UIM), a subscriber identity module (SIM), or a universal subscriber identity module (USIM), etc. The device having the identification module therein (hereinafter, referred to as ‘identification device’) may be manufactured in a smart card format. Accordingly, the identification device may be connected to the terminal 100 through a port.
The interface unit 170 may be a passage through which, when the mobile terminal is connected to an external cradle, power is supplied from the cradle to the mobile terminal 100, or various command signals input through the cradle by the user are delivered to the mobile terminal 100. The various command signals input from the cradle or the power may operate as a signal for recognizing that the mobile terminal 170 is exactly mounted to the cradle.
The controller 180 typically controls overall operations of the mobile terminal. For example, controls and processes related to a voice call, data communication, or a video call are performed. The controller 180 may include a multimedia module 181 for multimedia playback. The multimedia module 181 may be implemented inside the controller 180 or separately from the controller 180.
The controller 180 may perform pattern recognition processing for recognizing a hand-written input or drawing input performed on the touch screen as a letter and an image respectively.

Furthermore, a rear cut part 211 may be formed to allow a camera or other manipulation buttons prepared in the rear surface of the terminal body 100 to be exposed.
The terminal coupling part 210 may be coupled to the rear side of the rear housing 102 or coupled directly and detachably to the front housing 101 instead of the rear housing 102. In addition, when the middle frame is prepared, the terminal coupling part may be detachably coupled to the middle frame.
FIG. 3 illustrates an embodiment replacing the rear housing 102 of the terminal body 100 with the terminal coupling unit 210 of the terminal case 200. That is, the rear housing 102 is separated from the mobile terminal shown in FIG. 2 and, as shown in FIG. 3, the terminal coupling part 210 may replace the rear housing 102 and be coupled thereto. However, as described above, the coupling is not limited to this type, and the terminal coupling part 210 may be coupled to the rear side of the rear housing 102. When the terminal coupling part 210 is coupled to the rear side of the rear housing 102 of the terminal body 100, the mobile terminal means only the terminal body 100 and it may be interpreted that the terminal case 200 is a separate member detachable from the mobile terminal.
The front cover part 230 may have a thin plate shape and a shape corresponding to the front surface of the terminal body 100. A window 231 is prepared in the front cover part 230. The window 231 is transparently formed to allow a light emitted through the display unit 151 to be penetrable. The window 231 may be a hole that is formed by cutting a part of the front cover unit 230. In addition, a transparent film sheet can be coupled to and cover the hole for the window 231. Accordingly, when the window 231 is cut to penetrate in the depth direction of the front cover part 230, a user may see a picture or an image displayed on the display unit 151 of the terminal body 100, or make a touch input on the display unit 151 through the window 231. A magnetic material may be mounted to the front cover part 230. When the magnetic material is mounted to the front cover part 230, a magnetic field becomes changed according to an open or closed state of the front cover part 230. The sensing unit 140 prepared in the terminal body 100 may detect whether the front cover part 230 is open or closed through this magnetic field change. However, whether the front cover part 230 is open or closed is not always detected by a sensor using the magnetic material, but may be detected by another kind of proximity sensor or other sensors. Accordingly, there is not any limit in a method that the sensing unit 140 senses whether the front cover part 230 is open or closed.
The connecting part 220 connects the terminal coupling part 210 and the front cover part 230. Accordingly, one end of the connecting part 220 is coupled to the terminal coupling part 210 and the other end is coupled to the front cover part 230. The connecting part 220 is formed of a flexible material. Accordingly, in a state where the terminal coupling part 210 is coupled to the terminal body 100, the front cover unit 230 may be positioned so that the rear surface thereof contacts with the front surface of the terminal body 100, or positioned by rotating about 180 degrees so that the front surface thereof contacts with the rear surface of the terminal coupling unit 210.
FIG. 4 illustrates the front surface of the terminal case 200, namely, the front surface of the front cover part 230.
As described above, the window 231 is prepared in the front cover part 230 and a pattern part 240 is prepared below the window 231. The pattern part 240 is divided into a plurality of regions, and numbers or letters are displayed on each of the plurality of regions. That is, the pattern part 240 may include a plurality of buttons on which the numbers and letters are indicated. The pattern part 240 has a shape corresponding to a user interface displayed on the display unit 151 of the terminal body 100. Accordingly, when the pattern part 240 is divided into a A*B matrix, or includes buttons arrayed in a A*B matrix type, a user interface displayed on a region covered by the front cover part 230 in the display unit 151 may also be divided into a A*B matrix or have buttons, especially touch buttons, arrayed in a A*B matrix type. The pattern part 240 may display information about the user interface displayed on a region covered by the pattern part 240 in the display unit 151. Description about this will be provided later.
FIG. 5 is an exploded perspective view of the front cover part, FIG. 6 is a cross-sectional perspective view of a terminal case according to an embodiment, and FIG. 7 is a side cross-sectional view of a terminal case according to an embodiment. For reference, FIG. 5 illustrates a view that the front cover part 230 includes the pattern part 240, and FIG. 6 illustrates a view that the front cover part 230 does not include the pattern part 240.
Hereinafter, a structure of the front cover part 230 is described in detail with reference to FIGS. 5 to 7. In description of a configuration of the front cover part 230, referring that a configuration and another configuration are positioned to correspond to each other may mean that they are overlapped in a front and rear view.
The front cover part 230 includes a top cover 232, an actuator sheet 233, a supporting part 234, a poly dome sheet 235, an air vent part 236, and a bottom cover 237.
First, the top cover 232 forms the highest portion of the front cover part 230, namely, is positioned at the foremost side of the front cover part 230. Hereinafter, the highest portion and the foremost side should be interpreted as the same meaning, because the terms ‘the highest portion’ and ‘the foremost side’ can be selectively used according to a direction of view point. The top cover 232 may be made from leather, a synthesized resin, or other materials, but not limited thereto. The top cover 232 may be made from a material allowing a pressed point to be deformed, when a user presses the specific point on the top cover 232. That is, only the pressed point is dented toward the rear side. The top cover 232 includes a thru-hole part 232 a. The thru-hole part 232 a may be formed by cutting a part of the top cover 232. Accordingly, the thru-hole part 232 a may have a shape and size corresponding to the window 231 of the front cover unit 230. This means that an internal region of the thru-hole part 232 a of the top cover 232 may become the window 231 in view of the entire front cover part 230.
Furthermore, the top cover 232 includes a hard key cut part 232 b. The hard key cut part 232 b is formed by penetrating the top cover 232 in the depth direction (the up and down direction in FIG. 4). The hard key cut part 232 b may be formed at a position corresponding to any one of hard keys 131 of the mobile terminal, for example, a position corresponding to the home key. Accordingly, the user may perform a key input by pressing the hard key 131 even in a state where the front cover part 230 covers the entire front surface of the terminal body 100.
In addition, the front surface of the top cover 230 includes the pattern part 240 as shown in FIG. 4. The pattern part 240 may be printed on the front surface of the top cover 230, but is not limited thereto. The pattern part 240 may be identical to or correspond to at least any one of user interfaces displayed on the display unit 151 of the terminal body 100. That is, the pattern unit 240 may be that a user interface on the display unit 151, which is covered by the front cover part 230 and not shown to the user, is printed on the front cover part 230. Accordingly, when the user presses any one button marked on the pattern part 240, the same effect as that a button displayed on the display unit 151 of the terminal body 100 is pressed can be obtained. This operating method will be described later.
The actuator sheet 233 is positioned on a lower portion of the top cover 232, namely, in the rear side of the top cover 232.
The actuator sheet 233 includes a plurality of pressure bumps 233 a protruding towards the rear side (downward in FIGS. 5 to 7), a plurality of spacers 233 b, and a plurality of coupling bumps 233 c.
The pressure bumps 233 a is prepared to enable domes 235 a, which are to be described later, of the poly dome sheet 235 to be pressed. Accordingly, positions and the number of the pressure bumps 233 a correspond to those of the domes 235 a of the poly dome sheet 235. Description about this will be provided again, when the poly dome sheet 235 is described.
The spacers 233 b are extended longer than the pressure bumps 233 a towards the rear side (downward in FIGS. 5 to 7). The rear end portions of the spacers may normally contact with the poly dome sheet 235 to be described later. In detail, they may contact with other parts on which the domes 235 a are not formed in the poly dome sheet 235. Since the spacers 233 b secure spaces separated in a depth direction, the pressure bumps 233 a may move towards the rear side.
The coupling bumps 233 c is a configuration for coupling to the supporting part 234 to be described later and protrudes toward the rear side. The coupling bumps 233 c are formed at positions corresponding to coupling grooves 234 d in order to be inserted into the coupling grooves 234 d of the supporting part 234 to be described later.
The supporting part 234 may be formed from a material having higher rigidity than the top cover 232 and the bottom cover 237, and play a role of shaping the front cover part 230.
The supporting part 234 includes a center cut part 234 a, a thru-hole part 234 b, and a hard key cut part 234 c.
The center cut part 234 a is formed to penetrate a portion of the center of the supporting part 234 in the depth direction (the up and down direction in FIG. 4), has a little smaller area than the poly dome sheet 234. Coupling grooves 234 d are formed at the outer side of an edge of the center cut part 234 a.
The thru-hole part 234 b may be formed by penetrating the supporting part 234 in the depth direction (the up and down direction in FIG. 4). However, thru-hole part 234 b is not limited thereto, and may be formed from a transparent material such as a transparent film.
The hard key cut part 234 c is formed by penetrating the supporting part 234 in the depth direction (the up and down direction in FIG. 4). The hard key cut part 234 c may be formed at a position corresponding to any one of the hard keys 131 of the mobile terminal, for example, a position corresponding to the home key. Furthermore, it may also be formed at a position corresponding to the above-described hard key cut part 232 b of the top cover 232. Accordingly, the user may perform a key input by pressing a hard key (not shown) even in a state where the front cover part 230 covers the front surface of the terminal body 100.
The poly dome sheet 235 is positioned in the rear side (lower portion in FIGS. 5 to 7) of the actuator sheet 233. The poly dome sheet 235 includes the plurality of domes 235 a that the centers thereof convexly protrude towards the front side (upward in FIGS. 5 to 7). The plurality of domes 235 a may be separately disposed from each other in a predetermined interval. The domes 235 a are prepared, as briefly described above, at the positions corresponding to the pressure bumps 233 a. Here, the corresponding positions refer to positions at which the domes 235 a are overlapped the pressure bumps in a front side view. Accordingly, when the pressure bumps are pressed from the top portion to the bottom portion, the pressure bumps press the corresponding domes.
Carbon coating may be performed inside the domes 235 a. That is, the carbon coating may be performed at a bottom surface of the domes 235 a. Accordingly, when the domes 235 a are pressed by the pressure bumps 233 a, shapes of the domes 235 a may be deformed to cause a change of capacitance. In addition, the capacitance change is recognized by a touch sensor to allow a touch input to the mobile terminal to be performed.
The air vent part 236 is prepared in a lower portion of the poly dome sheet 235. The air vent part 236 may be provided as a type of tape having adhesion on any one side or on both sides. The air vent part 236 includes a plurality of circular parts 236 a. The circular parts 236 a are formed to penetrate the air vent part 236 in the depth direction. In addition, the circular parts 236 a are disposed separate from each other in a predetermined interval in correspondence to the positions of the domes 235 a. Furthermore, any one circular part 236 a communicates with at least any one of adjacent circular parts 236 a through communication parts 236 b. That is, connection paths are formed between any one circular part 236 a and adjacent circular parts 236 a thereof, and the connection paths become the communication parts 236 b. Accordingly, when the above-described domes 235 a of the poly dome sheet 235 are pressed, air inside the domes 235 a may be discharged into surrounding adjacent circular parts 236 a through the communication parts 236 b, and accordingly shapes of the domes 235 a may be deformed.
On the other hand, the circular parts 236 a respectively correspond to the domes included in the poly dome sheet 235. Accordingly, the number and positions of the circular parts 236 a correspond to those of the domes 235 a. Here, the corresponding means that each of the domes 235 a is disposed to overlap each of the circular parts 236 a in a view of the depth direction.
The bottom cover 237 is prepared in the rear side (the lower portion in FIGS. 5 to 7) of the air vent part 236. The bottom cover 237 is positioned at the rearmost side of the front cover part 230. Accordingly, the bottom cover 237 is disposed contactable with the display unit 151 of the mobile terminal. Hereinafter, the term ‘rearmost’ can be replaced to the term ‘lowest’ or ‘lowermost’ to describe the position of the bottom cover 237.
The bottom cover 237 includes a thru-hole part 237 a. The thru-hole part 237 a has the same shape as that of the thru-hole part 237 a of the top cover 232, and is prepared at a position corresponding to each other. The thru-hole part 237 a may be formed by cutting a portion of the bottom cover 237 to be penetrated in the depth direction.
The bottom cover 237 includes a hard key cut part 237 b. The hard key cut part 237 b is formed at a position corresponding to the hard key cut part 234 c of the above-described top cover 230.
The bottom cover 237 may be formed from leather, a synthesized resin, or other materials, and the material is not limited.
Furthermore, the thru-hole part 232 a of the top cover 232, the thru-hole part 234 b of the supporting part 234, and the thru-hole part 237 a of the bottom cover 237 are all formed transparently to allow a light to be transmitted therethrough, and form the window 231 of the front cover part 230. Accordingly, the window 231 includes the thru-hole part 232 a of the top cover 232, the thru-hole part 234 b of the supporting part 234, and the thru-hole part 237 a of the bottom cover 237.
Hereinafter, the operation principle of the front cover part 230 having the above-described structure is briefly described.
When a user presses any one button forming the pattern part 240 of the front cover part 230, a portion pressed on the top cover 232 is deformed and pushed out toward the rear side, and presses the corresponding pressure bump 233 a of the actuator sheet 233 towards the rear side.
When being pressed in the rear side, the pressure bump 233 a presses the corresponding dome 235 a towards the rear side.
When the dome 235 a is pressed towards the rear side, air inside the dome 235 a is dispersed toward adjacent domes through the air vent part 236, and the shape of the dome 235 a is deformed. That is, the space inside the dome 235 a gets smaller.
When the dome 235 a is deformed, an amount of the air filling the inside of the dome 235 a is changed to cause a change in capacitance inside the dome 235 a. In addition, this capacitance change is recognized by a touch sensor included in the terminal body. That is, the same effect is obtained as that a touch panel included in the display unit 151 of the mobile terminal is touched.
Accordingly, a touch input by a user is enabled even in a state where the display unit 151 of the mobile terminal, namely, the touch panel is covered with the front covert part 230.
Hereinafter, an operating method of the mobile terminal having the above-described configuration is described with reference to FIGS. 8 and 9. That is, description is provided for an operating method of a mobile terminal to which a signal may be input even in case where a user presses the front cover part 230.
In description about the operating method of the mobile terminal, the display unit 151 is divided into an exposed region 151 a and a hidden region 151 b as shown in FIG. 9. The exposed region 151 a is defined to be a region corresponding to the window 231 of the front cover part 230. That is, the exposed region 151 a is shown externally by the window 231, even in a state where the front cover part 230 covers the front side of the display unit 151. Furthermore, the hidden region 151 b is defined as a region other than the exposed region 151 a in the display unit 151, namely, a region covered by a portion other than the window 231 of the front cover part 230.
FIG. 8 is flowchart illustrating an operating method of a mobile terminal according to an embodiment.
First, the controller 180 obtains a user input turning on the display unit 151 (operation S101). The user input turning on the display unit 151 may be, for example, an input through the hard keys 131 such as a home key or a side key, but is not limited thereto.
When the user input turning on the display unit 151 is obtained, the controller 180 determines whether the front cover part 230 of the terminal case 200 is open or closed (operation S103).
When the hard keys 131 such as a home key or a side key is pressed and a signal therefrom is delivered to the controller 180, the controller 180 determines whether the front cover part 230 of the terminal case 200 is closed to cover the front surface of the terminal or the terminal case 200 is open to expose the front surface of the terminal. Here, whether the front cover unit 230 is open or closed is determined on the basis of sensing information of the sensing unit 140. Here, the sensing unit 140 may include a proximity sensor. When proximity to the front cover part 230 is sensed by the proximity sensor, the front cover part 230 is determined as closed. When proximity to the front cover part 230 is not sensed, the front cover part 230 is determined as open. However, it may be interpreted that whether the front cover part 230 is open or closed is not limited to the determination based on the sensing information from the proximity sensor, but other means may be used.
When the front cover part 230 is determined as open, the controller 180 enters a general mode and displays a user interface in the general mode on the display unit 151 (operation S105).
The general mode means a mode in which the mobile terminal operates in case where the terminal case is not coupled. That is, it is a mode in which the mobile terminal generally operates regardless of the terminal case. In the general mode, the user interface may be displayed on the entire region of the display unit 151.
Furthermore, when the front cover part is determined as closed, the controller 180 determines whether to enter a total close mode and display a user interface in the total close mode or enter a partial close mode and display a user interface in the partial close mode (operation S107).
The user interface in the total close mode is a user interface displayed in the hidden region 151 b, and may also be displayed through both of the hidden region 151 b and the exposed region 151 a. The user interface of the partial closed mode is a user interface displayed in only the exposed region 151 a and is not displayed in the hidden region 151 b.
Here, whether to enter the total close mode or the partial close mode may be determined by an input pattern of the hard key. For example, when a user performs a short press on the hard key, the user interface may be displayed only through the exposed region 151 a without activating the hidden region 151 b. When a user performs a long press on the hard key, the hidden region 151 b is also activated and the user interface may also be displayed through the hidden region 151 b. In addition, the reverse case is also possible. That is, when the short press is performed on the hard key, the total close mode may be entered, and, when the long press is performed on the hard key, the partial close mode may be entered. However, this selection is not determined only by the length of time while the hard key is pressed. Different methods other than input time of the hard key, for example, whether to press several times shortly or to press once may be used to select the total close mode or the partial close mode. However, the selection method is not limited thereto, and various methods may be used.
Furthermore, as a result of determining whether to be in the total close mode or in the partial close mode, when it is determined as the total close mode, the controller 180 displays the total close mode user interface through the hidden region 151 b of the display unit 151 (operation S109).
Here, on the exposed region 151 a, the user interface may be displayed or may not be displayed. In addition, in the total close mode, although only the exposed region 151 a is visually observed by the user, a touch input is also possible through the hidden region 151 b. FIG. 9 illustrates an example that a user interface is displayed on both the exposed and hidden regions 151 a and 151 b of the display unit 151. The user interface shown in FIG. 9 is a user interface for executing a phone call function.
In this state, when the user presses the hidden region 151 b, the controller 180 obtains a touch input signal corresponding thereto (operation (S111).
Here, the front surface of the front cover part 230 includes the pattern unit 240 and information about the buttons or icons included in the user interface displayed in the hidden region 151 b is displayed through the pattern part 240. Accordingly, although the front cover part 151 b is covered by the hidden region 151 b, the user may know which portion is necessary to be pressed in order to input a desired signal.
When the pattern part 240 of the front cover part 230 is pressed, the top cover 232 is pressed towards the rear side, the pressure bump 232 a is pushed out towards the rear side, the pressure bump 233 a again press the dome 235 a towards the rear side to deform the shape thereof, and a capacitance change is recognized by the touch sensor. However, even though a configuration such as the pressure bumps 233 a or the domes 235 a does not exist, a touch input by a finger or a stylus pen may be recognized by the touch sensor.
When receiving the touch input signal, the controller 180 displays information corresponding to the touch input through the exposed region 151 a (operation S113).
That is, letters or numbers corresponding to touch input buttons are displayed on the exposed region or an application corresponding to a touch input icon is executed.
Furthermore, in operation S107, when determining to enter the partial close mode, the controller 180 displays a user interface in a partial close mode through the exposed region 151 a (operation S115). Here, the user interface is not displayed in the hidden region 151 b.
In addition, when a user touches the exposed region 151 a, the controller 180 obtains the input signal (operation S117).
The controller 180 displays information corresponding to the input touch signal on the exposed region 151 a (operation S119).
Here, a specific application may be executed by the touch input.
In the above-described embodiment, when the front cover part 230 is determined as closed in operation S107, the controller 180 determines whether to be the total close mode or the partial close mode.
However, when obtaining a user input turning on the display unit 151, the controller 180 may omit the determining of whether to enter the total close mode or the partial close mode, unconditionally enter the total close mode, and display the user interface in the total close mode.
Hereinafter, an operating method of the terminal case and the mobile terminal according to another embodiment is described with reference to FIGS. 10 to 12.
In the present embodiment, a plurality of close modes are provided to enable a user to select, and a user interface in the selected close mode is provided to the user.
FIG. 10 illustrates an exemplary user interface that a plurality of close modes are provided to allow a user to select. Here, a portion of the plurality of close modes provided to be selectable may be the total close mode displaying the user interface only through the hidden region 151 a or through all the hidden region 151 a and the exposed region 151 b, and another portion thereof may be the partial close mode displaying the user interface only through the exposed region 151 a.
FIG. 10 illustrates a user interface displayed in the exposed region 151 a and including four buttons through which the user can select any one of a phone call, a text message transmission, application array, and music playback. Here, nothing may be displayed in the hidden region 151 b.
FIG. 11 illustrates a user interface representing a case where any one of the four buttons of the user interface shown in FIG. 10 is touched.
FIG. 11A illustrates a user interface displayed when the phone call button is pressed. Number buttons, a call button, a call log button, and a backspace button are displayed in the hidden region 151 b for allowing a user to make a phone call. In this case, the user interface shown on the hidden region 151 b is divided to correspond to the pattern part 240 of the front cover part 230. Here, ‘to correspond’ means that each button included in the pattern part 240 and each button displayed on the hidden region 151 b are disposed to overlap in a front side view. In addition, ‘to correspond’ also means that a user interface in a first close mode has region division corresponding to region division of the pattern part 240 formed on the front cover part 230. That is, when the pattern part 240 is divided into an A*B matrix or includes buttons arrayed as an A*B matrix, the user interface may also be divided into an A*B matrix or include buttons arrayed as an A*B matrix. Furthermore, information (numbers or letters) corresponding to buttons input through the pattern part 240 and the hidden region 151 b may be displayed on the exposed region 151 a. Here, A and B are arbitrary numbers.
FIG. 11B illustrates a user interface displayed when the text message transmission button is pressed. Letter buttons formed of consonants and vowels are displayed in the hidden region 151 b for allowing a user to be able to transmit a text message. Here, the user interface on the hidden region 151 b, as in the first close mode, may have region division corresponding to region division of the pattern part 240 formed on the front cover part 230. That is, when pattern part 240 is divided into an A*B matrix or includes buttons arrayed as an A*B matrix, the user interface may also be divided into an A*B matrix or include buttons arrayed as an A*B matrix.
FIG. 11C illustrates a user interface displayed when the application array button is pressed. A plurality of user-preset user application icons may be arrayed to allow a user to execute any one application. Here, positions at which the applications are arrayed respectively correspond to buttons of the pattern part 140. That is, as in the first and second close modes, the user interface displayed on the hidden region 151 b may have region division corresponding to the region division of the pattern part 240 which is formed on the front cover part 230. That is, when the pattern part 240 is divided into an A*B matrix or includes buttons arrayed as an A*B matrix, the user interface may also be divided into an A*B matrix or include buttons arrayed as an A*B matrix.
Furthermore, information (numbers or letters) corresponding to buttons input through the pattern part 240 and the hidden region 151 b may be displayed on the exposed region 151 a. Alternatively, application execution information may be displayed on the exposed region 151 a. For example, when an application related to music playback is executed, information related to the music playback may be displayed on the exposed region 151 a.
In addition, a plurality of application icons displayed on the hidden region 151 b may be arrayed at positions corresponding to the buttons of the pattern part 240 one by one. Alternatively, as shown in FIG. 11C, any one icon may be arrayed in plurality. That is, an application icon of a high use frequency may be arrayed in correspondence to the plurality of buttons of the pattern part 240. In this case, since the displayed application may be set by a user and the setting may be changed, the corresponding application may not be displayed on the pattern part 240. However, it is also possible that information about a part of applications is displayed on the patter part 240 and a user sets so that the corresponding applications are disposed at the corresponding positions.
FIG. 11D illustrates a user interface displayed when the music playback button is pressed. That is, when a user touch-inputs a music playback button in the user interface shown in FIG. 10, the corresponding application may be instantly executed. In addition, information about the played music may be displayed in the exposed region 151 a.
Furthermore, when a selectable user interface in the total close mode is in plurality, only information about a part of the user interfaces is displayed on the pattern part 240, and information about rest of them may be not displayed.
In the present embodiment, only information corresponding to phone call and text message transmission is displayed on the pattern part 240, but information about the application array is not displayed on the pattern part 240. Accordingly, only numbers, letters, or icons corresponding to the user interface for the phone call and the text message transmission are displayed on the pattern part 240.
Hereinafter, an operating method of a mobile terminal according to another embodiment, which provides the user interface as shown in FIGS. 10 and 11, is described with reference to FIG. 12.
The controller 180 obtains a user input turning on the display unit 151 (operation S201).
Here, the user input turning on the display unit 151 may be performed by pressing a home key or a side key, but is not limited thereto.
When the user input turning on the display unit 151, the controller 180 determines whether the front cover part 230 of the terminal case is open or closed (operation S203).
For example, when a hard key such as the home key or the side key is pressed and a signal therefrom is delivered to the controller 180, the controller 180 determines whether the front cover part 230 of the terminal case is closed to cover the front surface of the terminal or the terminal case is open to expose the front surface of the terminal. Here, whether the front cover part 230 is open or closed may be determined based on sensing information of a proximity sensor. That is, when proximity to the front cover part is sensed by the proximity sensor, the front cover part is determined as closed, and, when proximity to the front cover part is not sensed by the proximity sensor, the front cover part is determined as open. However, whether the front cover part 230 is open or closed is not always determined on the basis of the sensing information from the proximity sensor, but may be determined by using other means.
When the front cover part 230 is determined as open, the controller 180 enters a general mode and displays a user interface in the general mode through the display unit 151 (operation S205).
Furthermore, when the front cover part is determined to be closed, the controller 180 displays, on the exposed region 151 a, a user interface in which any one user interface may be selected from among a plurality of user interfaces (operation S207).
For example, a user interface may be displayed where any one of a plurality of user interfaces including at least any one of a phone call, text message transmission, application array, and music playback.
Furthermore, the controller 180 obtains a user input selecting any one user interface through the exposed region (operation S209).
The controller 180 displays the selected user interface on the hidden region 151 b (operation S211).
That is, the user interface of the selected total close mode is displayed on the hidden region 151 b. Here, the displayed user interface, as shown in FIGS. 11A to 11C, is provided to receive a touch input signal through the hidden region 151 b. However, the user interface in the partial close mode, as shown in FIG. 11D, may be displayed only through the exposed region 151 a.
In a state where the user interface is displayed in the hidden region 151 b, when the user presses the pattern part 240 to touch-input any one part on the hidden region 151 b, the controller 180 obtains the touch input through the hidden region 151 b (operation S213).
When the user presses a predetermined button of the pattern part 240, an effect is obtained that a corresponding position on the display unit 151 is touched. This is because, when the pattern part 240 of the front cover part 230 is pressed, the top cover 232 is pressed towards the rear side, the pressure bump 233 a is pushed out towards the rear side, the pressure bump 233 a again press the dome 235 a towards the rear side to deform the shape thereof, a capacitance change therefrom is recognized by the touch sensor, and the touch input is recognized.
Furthermore, when the controller 180 obtains a touch input through the hidden region, information corresponding to the touch input is displayed in the exposed region 151 a (operation S215).
For example, in a state where a phone call user interface is displayed, when the user presses numbers, corresponding numbers are displayed in the exposed region. When the user presses the entire phone number and a call button, a phone call starts and a call connection situation is displayed on the exposed region.
In addition, in a state where a text message transmission user interface is displayed, when the user presses letters, corresponding letters are displayed in the exposed region. When the user presses all letters desired to be transmitted and a transmission button, the text message is transmitted and a text message transmission situation and a result thereof are displayed in the exposed region.
In addition, in a state where a user interface having a plurality of icons for executing applications is displayed, when the user presses a position corresponding to any one application, a corresponding application is executed and information about the execution of the corresponding application may be displayed in the exposed region.
Furthermore, when a button for executing any one of the plurality of applications shown in FIG. 10C is displayed in operation S207, the corresponding application may be further rapidly executed.
For example, a music playback application is displayed in operation S107 and also in operation S211. Accordingly, in order to further rapidly execute any one of the plurality of applications included in the application array user interface, the one application may be allowed to be displayed in operation S107.
According to the terminal case and the mobile case, user convenience can be improved because a touch input is enabled through a part that a front surface is covered even in case where the front surface of the mobile terminal is covered with the terminal case.
FIG. 13 illustrates another shape of the front cover part 230 a.
The pattern part 240 a of the front cover part 230 a may be formed to have a structure allowing a light to be transmitted as shown in FIG. 13. That is, the pattern part may have a structure allowing a user interface displayed on the display unit 151 to be shown to the user, but not have a printed shape corresponding to the hidden region.
For this, the pattern part 240 a may be formed from a material allowing a light to be transmitted. The pattern part 240 a may have lower light transmittance than a window 231 a. The window 231 a may be a thru-hole or a transparent window by coupling the transparent film sheet to the thru-hole.
In addition, a light emitted from the display unit 151 may be allowed to be transmitted through the entire pattern part 240 a, or through a part of the pattern part 240 a.
For example, only boundary portions of buttons forming the pattern part 240 a may be allowed to transmit a light by allowing only a plurality of straight line parts dividing the pattern part 240 a to transmit the light. Alternatively, an effect that numbers or letters displayed on the pattern part 240 a emit lights may also be obtained by allowing portions corresponding to the numbers or the letters displayed on the pattern part 240 a to transmit the lights.
FIG. 14 illustrates the front surface of the terminal case 200 b according to another embodiment. The terminal case 200 b according to the present embodiment includes a terminal coupling part (not shown) from which the mobile terminal is detachable, and a front cover part 230 b coupled in a foldable way to the terminal coupling part and able to cover the front surface of the display unit of the mobile terminal. The front surface of the front cover part 230 b includes a pattern part 240 b. In addition, the front cover part 230 b includes a window 231 b. The window 231 b may be a thru-hole or a transparent window by coupling the transparent film sheet to the thru-hole.
A basic configuration and operation principle of the terminal case 200 b shown in FIG. 14 are the same as those of the embodiment described with reference to FIGS. 1 to 11.
However, there is a difference in that the pattern part 240 b may have a shape of a QWERTY keyboard and the window 231 a is formed to be long in a horizontal direction.
When the terminal case 200 b has this configuration, a user interface displayed in the hidden region may include a QWERTY keyboard corresponding to the shape of the pattern part 240 b.
