Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

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

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection fluorescent light sensor, a mirror reflection fluorescent light sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have.

The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

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

Touch can be sensed.

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

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

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

A user of the mobile terminal including at least one of the above-mentioned components must first operate the operating system for use of the mobile terminal. The operation that drives these operating systems can be called "booting". The term " boot " may include the meaning of driving an operating system, starting an operating system, or loading an operating system into memory. Such booting may be replaced by other terms having similar meanings by those skilled in the art.

Conventionally, a mobile terminal has booted by a boot command input by a user. That is, the conventional mobile terminal can not boot if there is no user boot instruction.

However, the present invention proposes a method of performing booting automatically according to the detachment of a battery without a user's booting command. Hereinafter, a control method for automatically booting a mobile terminal in a mobile terminal according to the present invention will be described in more detail with reference to the drawings.

2 is a flowchart illustrating a control method for booting a mobile terminal in a mobile terminal according to an embodiment of the present invention. 3 is a block diagram showing a power supply circuit for managing the power supply of the mobile terminal according to the present invention.

Referring to FIG. 2, a mobile terminal according to an exemplary embodiment of the present invention may detect a state of a power supply circuit (S210).

The main body of the mobile terminal according to the present invention may include a power supply circuit for power management. The power supply circuit is a circuit that performs a function of managing power used in the system of the mobile terminal. Such a power supply circuit converts a single voltage output from the battery into a voltage of a proper type required by each component of the mobile terminal and supplies power to each component.

One example of such a power supply circuit is a circuit in which power management integrated circuit (PMIC) technology is implemented.

3, the PMIC 300 includes a buck converter 310, a boost converter 320, an LDO (Low Dropout Regulator) 330 for voltage conversion, a battery charging unit (I2C) 350 for power management, a boot signal unit 360 for booting the mobile terminal, .

The boot signal unit 360 is a component for generating a boot signal for driving an operating system installed in the mobile terminal using the driving power received from the battery. Here, the boot signal may mean an electrical signal for starting the operation of the operating system.

For example, the boot signal unit 360 generates a boot signal based on the fact that the drive power is supplied to the boot signal unit 460 from the battery and the drive power is converted into 0 for a predetermined time .

The boot signal unit 360 may generate a boot signal through different paths according to different conditions. For example, the boot signal unit 360 may generate a boot signal through the first path when the first condition is satisfied, and may generate the boot signal through the second path if the second condition is satisfied . Here, the first path and the second path may also be referred to as a first circuit and a second circuit, respectively, as paths through which signals are generated.

In addition to the above components, the PMIC includes circuits that perform various functions for power management of the system. The configuration of these circuits may vary from manufacturer to manufacturer. In the following description, the configuration described in terms of the power supply circuit will be described in terms of the boot signal unit 360 of the power supply circuit. Also, the power supply circuit can be understood to have the same meaning as the PMIC.

The power supply circuit may have different states depending on whether or not the battery is detachably attached to the main body.

More specifically, the power supply circuit may have a first state in which the battery is detached from the main body of the mobile terminal and the driving power is not supplied from the battery. In addition, the power supply circuit may have a second state in which a battery is attached to the main body of the mobile terminal and the driving power is supplied from the battery. In this case, the second state may be expressed as a standby state in which a standby current flows in the mobile terminal.

The state in which the main body and the battery are detached may mean a state in which the first connector formed on the main body and the second connector formed on the battery are not in contact (or electrically connected). On the contrary, the state where the main body and the battery are attached means the state where the first connector formed on the main body and the second connector formed on the battery are in contact (or electrically connected).

The power supply circuit may receive driving power from the battery through the first connector when the battery is attached to the main body. The battery can supply driving power to the power supply circuit when the power charged in the battery (i.e., remaining battery power) is equal to or greater than a predetermined amount. For example, when the battery has a voltage of 2.5 V or more, the battery can supply driving power to the power supply circuit through the first and second connectors.

Alternatively, when the power charged in the battery is less than a predetermined amount, the battery may not supply the driving power to the power supply circuit. For example, when the power charged in the battery is less than 0 to 2.5 V, the battery may not supply driving power to the power circuit even when the main body and the battery are attached. The state of the power supply circuit in which the battery and the main body are attached but the driving power is not supplied can be named as the third state.

In order to determine whether the power supply circuit is in any one of the first, second, and third states, the power supply circuit may first detect whether the main body and the battery are in contact with each other.

Here, the power supply circuit may further include a contact sensing unit (not shown) for sensing whether the first connector formed on the main body and the second connector formed on the battery are in contact with each other. The contact sensing unit may sense whether the first connector and the second connector are electrically connected.

In addition, the power supply circuit may detect whether the driving power is supplied from the battery. For example, the power supply circuit may sense a state in which driving power is supplied from the battery or a state in which no driving power is supplied from the battery.

Thereafter, the power supply circuit supplies a first state in which the main body and the battery are detached and does not supply the driving power according to the detection result, a second state in which the main body and the battery are attached to supply the driving power, Or a third state in which the driving power is not supplied, although it is attached to the display panel.

Thereafter, the mobile terminal according to the embodiment of the present invention can generate the boot signal through different paths based on the different conditions being satisfied (S220).

A mobile terminal according to an embodiment of the present invention can generate a boot signal through different paths of a power supply circuit.

More specifically, the power supply circuit may comprise a first path and a second path for generating a boot signal. For example, the power supply circuit may generate a boot signal through a first path electrically coupled to the CBL_PWR_N pin that constitutes the PMIC and a second path electrically coupled to the KPD_PWR_N pin.

A mobile terminal according to another embodiment of the present invention may generate a boot signal through a first path constituting a power supply circuit and a second path constituted by an external circuit electrically connected to the power supply circuit. For example, a boot signal can be generated through a first path composed of a one-shot IC electrically connected to the PMIC circuit and a second path electrically connected to a KPD_PWR_N pin constituting the PMIC circuit.

The different conditions for generating the boot signal according to the present invention may be a condition related to the state of the power supply circuit due to detachment of the main body and the battery. For example, the different conditions may include: i) the battery is attached to the main body in a first state in which the battery is detached from the main body and the power circuit does not receive the driving power from the battery, And ii) a second condition in which a boot command is received through the user input unit in a second state in which the power supply circuit receives the driving power from the battery.

The power supply circuit can generate the boot signal through at least one of the first path and the second path based on the fact that different conditions are satisfied.

For example, in the power supply circuit, the battery is attached to the main body in a first state in which the battery is detached from the main body and the power supply circuit does not receive the driving power from the battery, The boot signal can be generated through the first path based on satisfaction of the first condition that the first condition to be switched to the second state to be supplied is satisfied.

As another example, the power supply circuit may be configured to boot through the second path based on the satisfaction of the second condition that the boot instruction is received through the user input unit in the second state in which the power supply circuit receives the driving power from the battery, Signal can be generated. Here, the user input portion is replaced with the description of FIG. 1A as the constituent elements described with reference to FIG. 1A.

When the boot signal is generated in the power circuit, the mobile terminal can operate the operating system in response to the boot signal (S230).

When the boot signal is generated, the power circuit of the mobile terminal can operate the operating system of the mobile terminal. That is, the mobile terminal can perform booting in response to the boot signal.

More specifically, the power supply circuit supplies power for booting to the main body, so that the control unit 180 of the mobile terminal loads the operating system into the memory 170, State.

The user can use the mobile terminal when the operation of the operating system is completed.

Meanwhile, the control unit 180 may satisfy a predetermined condition during operation of the operating system, or may shut down the operating system of the mobile terminal according to a control command of the user. The shutdown may mean the operation of the mobile terminal that terminates the operation of the operating system.

For example, the control unit 180 may terminate the operation of the operating system in response to the input of a shutdown command through the user input unit.

In the above, a control method of performing booting of the mobile terminal in the mobile terminal according to the present invention has been described.

Hereinafter, a configuration and operation of a power supply circuit of a mobile terminal according to an embodiment of the present invention for implementing the control method described with reference to FIG. 2 will be described. 4A to 4C are conceptual diagrams showing the configuration of a power supply circuit of a conventional mobile terminal. 5A and 5B are conceptual diagrams showing a configuration of a power circuit of a mobile terminal according to an embodiment of the present invention. 6 and 7 are flowcharts illustrating an operation of a power circuit of a mobile terminal according to an exemplary embodiment of the present invention.

Conventionally, the power circuit of the mobile terminal includes a single path for generating a boot signal. For example, referring to FIG. 4A, the power supply circuit 300 may generate a boot signal through a path connected to the KPD_PWR_N pin 361. [

The KPD_PWR_N pin 361 is a keypad power amp pin and is a connection terminal connected to a path for generating a boot signal based on a boot command received via a user input unit.

For example, the switching circuit connected to the KPD_PWR_N pin is not connected to ground, as shown in FIG. 4A, if there is no boot instruction via the user input. In this case, although not shown, the power supply circuit is connected to the battery and is supplied with driving power.

Meanwhile, when a boot command is input through the user input unit, the power circuit may be connected to a ground (GND) as shown in FIG. 4B. In this case, the voltage applied to the power supply circuit may be 0V.

At this time, as shown in FIG. 4C, in the path connected to the KPD_PWR_N pin, a pulse signal having a driving power of 0 V can be generated. More specifically, before the boot command is received through the user input unit while the drive power is supplied from the battery between t1 and t2, there may be a voltage of 1.8 V corresponding to the drive power source at the point corresponding to the KPD_PWR_N pin . On the other hand, when the boot instruction is inputted through the user input unit at t2 and the power supply circuit is connected to the ground, the voltage applied to the point corresponding to the KPD_PWR_N pin may be changed to 0V. In this case, the voltage drop (1.8V-> 0V) may occur in the path connected to the KPD_PWR_N pin. At this time, a boot signal may be generated through a path connected to the KPD_PWR_N pin based on the fact that the voltage drop occurs during a preset time t0.

Through this, the conventional mobile terminal has operated the operating system.

However, the mobile terminal according to the present invention can perform the booting automatically according to the detachment of the battery.

To this end, the power circuit of the mobile terminal according to an embodiment of the present invention may include different paths for generating a boot signal.

The different paths may be independent electrical paths. In addition, the different paths may be understood as separate and different circuits included in the electric circuit.

5A, a power supply circuit 300 of a mobile terminal according to an exemplary embodiment of the present invention includes a first path electrically connected to the CBL_PWR_N pin 362 and a second path electrically connected to the second path electrically connected to the KPD_PWR_N pin 361. [ Path < / RTI > Here, the CBL_PWR_N pin 362 may be a connection terminal connected to a path formed to generate a boot signal based on the battery being coupled to the main body. Also, the second path may be a path connecting the CBL_PWR_N pin 362 to the ground.

In this case, the power supply circuit can perform booting in accordance with the control method described with reference to Fig.

More specifically, when the battery is attached to the main body in the first state in which the battery is detached from the main body and is not supplied with the driving power from the battery, and the second state is switched from the battery to the second state, the CBL_PWR_N pin The boot signal can be generated through the first path electrically connected to the first bus 362. In this case, as shown in Fig. 5B, the voltage of the CBL_PWR_N pin may drop to a voltage of 0V at 1.8V when the battery is attached to the main body and the driving power is supplied from the battery. Through this, the second path can generate a boot signal corresponding to the voltage drop.

Accordingly, the present invention can perform automatic booting of the mobile terminal only by the user's operation of contacting the battery to the main body. Therefore, the present invention can automatically perform booting and shorten the boot time even if the user does not issue a separate boot command for booting.

5A, when the boot command is input through the user input unit in the second state in which the battery is attached to the main body and the drive power is supplied from the battery, the power supply circuit 300 shown in Figs. 4A and 4B The boot signal can be generated through the second path electrically connected to the KPD_PWR_N pin 361 in the same manner as the booting signal.

On the other hand, the first path included in the power supply circuit 300 of FIG. 5A may be switched from the active state to the inactive state to generate the boot signal according to the second path when the operating system is driven. Here, the activated state means that the boot signal can be generated through the first path, and the inactive state means that the boot signal can not be generated through the first path.

6, the control unit 180 of the mobile terminal can determine whether the power supply circuit is in a second state in which the battery is attached to the main body and the driving power is supplied to the power supply circuit (S610) .

If the power supply circuit is in the second state, the control unit 180 may determine whether booting is completed (S620).

If the booting is completed, the control unit 180 may set the first path included in the power supply circuit to the inactive state (S630).

That is, when the booting is completed, the controller 180 sets the first path to the inactive state and stores the set information in the inactive state in the memory (or the register).

In this case, the control unit 180 can generate the shutdown signal through the second path in accordance with the shutdown command input through the user input unit. If the first path is not inactivated, that is, because the power supply circuit is electrically connected to the ground by the first path, the control unit 180 can not generate the shutdown signal in response to the shutdown command.

In addition, the control unit 180 can generate the boot signal through the second path in accordance with the boot command input through the user input unit, in the power supply circuit in the second state, when the first path is in the inactive state . If the first path is not inactivated, the controller 180 controls the power supply circuit to be connected to the ground through the first path. Accordingly, in response to the boot command input through the user input unit, Can not be generated.

When the first path is inactivated, the mobile terminal according to the present invention can generate the boot signal only through the second path.

Accordingly, since the present invention provides the same function as the conventional one after connecting the battery to the main body, it is possible to induce the use of the natural mobile terminal without learning to the user using the conventional mobile terminal. Further, according to the present invention, when the booting of an unwanted mobile terminal is performed due to the execution of the automatic boot, the mobile terminal can be operated again through arbitrary operation of the user.

Referring to FIG. 7, the power supply circuit 300 according to FIG. 5A can detect whether the main body and the battery are detachable or not in a state in which the first path is inactivated (S710).

The controller 180 can sense whether the first connector formed on the main body and the second connector formed on the battery are in contact with each other through the touch sensing unit included in the power supply circuit 300 or the separately configured sensing unit.

When the main body is detached from the battery, the controller 180 may switch the first path from the inactive state to the active state in operation S720.

More specifically, when the main body is detached from the battery, the controller 180 can not receive the driving power from the battery, thereby stopping the operation. At this time, the supply of driving power may also be stopped to the memory (or the register) of the mobile terminal storing the setting information in which the first path is set to the inactive state. In this case, the memory (or the register) may lose the setting information in which the first path is set to the inactive state. That is, the setting information stored in the memory (or the register) can be deleted.

In this case, the first path can be switched from the inactive state to the active state by disappearing the setting information. That is, the first path may be set to a default value again.

In this case, the mobile terminal according to the embodiment of the present invention can perform the booting automatically according to the detachment of the battery.

On the other hand, although not shown, an internal resistance may be included in the first path connected to the CBL_PWR_N pin of the power supply circuit 300 of FIG. 5A. More specifically, the internal resistance may be an internal pull-up resistor. The pull-up resistor is a resistor that connects the power supply and the power supply circuit in order to prevent malfunction of the circuit. This pull-up resistor applies a specific voltage to the power supply circuit while the switch is not pressed, and connects the power supply circuit to the ground when the switch is pressed.

At this time, the controller 180 of the mobile terminal according to an embodiment of the present invention may deactivate the pull-up resistor together with the deactivation of the first path. Also in this case, setting information indicating that the pull-up resistor is set to the inactive state may be stored in the memory (or the register) of the mobile terminal.

Through this, the present invention can prevent the leakage current due to the pull-up resistor.

The setting information indicating that the pull-up resistor stored in the memory (or the register) is set to the inactive state is similar to the setting information indicating the inactive state of the first path described above, , It may disappear from the memory (or register).

Accordingly, the present invention can enable normal operation of the first path when the battery is reattached.

The configuration and operation of the power supply circuit of the mobile terminal for booting according to the battery detachment and attachment in the mobile terminal according to the embodiment of the present invention have been described above.

Hereinafter, a configuration and operation of a power supply circuit of a mobile terminal for booting according to a battery detachment and attachment in a mobile terminal according to another embodiment of the present invention will be described. FIG. 8 is a flowchart illustrating a method of generating a boot signal in accordance with another embodiment of the present invention in a power circuit of a mobile terminal. 9A and 9B are conceptual diagrams showing the configuration and operation of a power supply circuit that performs the control method of FIG.

The power supply circuit 300 of the mobile terminal according to another embodiment of the present invention may further be connected to a one-shot circuit 800 as shown in FIG. 8A. That is, the power supply circuit may further include a one-shot circuit. Therefore, the one-shot circuit is a circuit which is provided separately from the power supply circuit and is electrically connected to the power supply circuit, and can be understood as a component of the power supply circuit. However, the present invention is not limited to this, and the one-shot circuit and the power supply circuit may be understood as independent components.

The one-shot circuit is a circuit composed of a timer and a push button, and can generate one signal when a single input is applied.

More specifically, the one-shot circuit can generate a boot signal when driving power is supplied from a battery and an input signal corresponding to the driving power is received.

The boot signal generated in the one-shot circuit is transmitted to the power supply circuit, and the mobile terminal can start operating the operating system in response to the boot signal transmitted to the power supply circuit.

When an input signal corresponding to the driving power source is received at the time point t1 in the one-shot circuit, a boot signal as shown in FIG. 8B can be generated. The boot signal can be checked through the voltage applied to the KPD_PWR_N pin.

Such a one-shot circuit may include various components in addition to the timer and the push button.

Hereinafter, a control method for performing booting in a mobile terminal having a power supply circuit according to another embodiment of the present invention will be described in more detail.

9, a mobile terminal according to another embodiment of the present invention can determine the state of a power supply circuit (S910).

The determination of the state of the power supply circuit is the same as that of step S210 described above, and the description thereof is replaced by step S210. In addition, the same terms as those described above with reference to Fig. 2 will be replaced with the description of Fig.

When the power supply circuit is switched from the first state to the second state, the mobile terminal may generate a boot signal for operating the operating system through a first path included in the power supply circuit (S920).

The first path may be a path composed of a one-shot circuit. The one shot circuit can generate a boot signal based on an input signal corresponding to the drive power source when the drive power source is inputted from the battery.

More specifically, the one-shot circuit can generate a pulse signal in accordance with an input signal corresponding to the driving power source, as shown in Fig. 8B. At this time, the one-shot circuit can generate a boot signal at a time t2 when the voltage of the pulse signal drops.

That is, the one-shot circuit can automatically generate the boot signal when the battery is attached to the main body and the driving power is supplied to the one-shot circuit in a state where the battery is detached from the main body.

Also, after generating the boot signal, the one-shot circuit may not generate a boot signal any more if the battery continues to be attached to the main body. That is, the one shot circuit may not generate additional boot signals after a single input signal.

The boot signal generated in the first path may be transferred to the second path (S930). As shown in FIG. 8A, one end of the one-shot circuit may be electrically connected to a second path included in the power supply circuit through the KPD_PWR_N pin.

The boot signal generated in the first path is transmitted to the system of the mobile terminal through the second path, and the mobile terminal can operate the operating system based on the boot signal in operation S940.

In addition, the power supply circuit according to another embodiment of the present invention can generate a boot signal through the second path based on the boot command input through the user input unit, as in the conventional mobile terminal.

In this case, booting can be performed similarly to the conventional mobile terminal.

In the foregoing, a method of generating a boot signal according to detachment and attachment of a battery in a power supply circuit according to another embodiment of the present invention has been described.

Accordingly, the user can conveniently boot the mobile terminal by simply detaching and attaching the battery.

Hereinafter, a method of performing booting of the mobile terminal according to the remaining battery level will be described. 10 is a flowchart showing a method of performing booting of the mobile terminal according to the remaining battery level.

The control unit 180 of the mobile terminal according to the present invention can determine whether to operate the operating system according to the magnitude of the driving voltage. Here, the magnitude of the driving voltage can be determined by the remaining battery power. For example, when the remaining battery level is less than 0 to 2.5V, the drive voltage is 0V, and when the remaining battery level is less than 3.2V at 2.5V or more, the drive voltage has the same level as the remaining battery level, V, the driving voltage may be 3.2V. That is, the control unit 180 can determine whether the operating system is operated according to the remaining amount of the battery.

10, when a driving voltage is supplied from a battery, the power circuit of the mobile terminal according to the present invention includes at least one of a first path and a second path included in the power supply circuit Through the path, a boot signal can be generated (S1010).

The power supply circuit can generate a boot signal using the drive power source when the drive power source is received from the battery.

On the other hand, the battery may not supply driving power to the power supply circuit when the amount charged in the battery is less than the 2.5V voltage. In this case, the power supply circuit can not generate a boot signal.

Alternatively, the battery can supply driving power to the power supply circuit when the amount of the battery charged is 2.5 V or more. In this case, the power supply circuit can generate a boot signal.

In response to the boot signal, the controller 180 may check the magnitude of the driving voltage before starting the operation of the operating system. More specifically, the control unit 180 may determine whether the remaining amount of the battery is less than a predetermined amount (S1020). The predetermined amount may be a minimum amount of power required to drive the operating system, for example, a driving voltage of 3.2 V or more.

That is, when the driving power of less than 3.2 V is supplied from the battery at 2.5 V, the control unit 180 can generate the boot signal but can not complete booting.

If the remaining amount of the battery is less than the predetermined amount, the control unit 180 stops the operation of the operating system and outputs notification information indicating that the operation of the operating system is interrupted (S1030).

The controller 180 may determine that the operation of the operating system can not be completed when the remaining amount of the battery is less than the predetermined amount. In this case, the control unit 180 may stop the operation of the operating system. That is, the boot can be terminated.

When the operation of the operating system is interrupted, the controller 180 may output notification information indicating that the operation of the operating system is interrupted so that the user can recognize the operation.

Such announcement information may be output in at least one of a visual, auditory, and tactile manner. For example, the control unit 180 can visually display notification information on the display unit 151 or output a notification sound through a speaker.

Alternatively, the control unit 180 may drive the operating system if the remaining amount of the battery is equal to or greater than a preset amount (S1040). In this case, the controller 180 can drive the operating system using the driving power received from the battery. That is, when the controller 180 receives a driving power of 3.2 V or more from the battery, the controller 180 can operate the operating system.

In the above, a method of operating the operating system according to the remaining amount of the battery has been described.

Hereinafter, a battery detachment / attachment structure of a mobile terminal according to an embodiment of the present invention will be described. 11A to 11C are conceptual diagrams illustrating a battery detachment / attachment structure of a mobile terminal according to an embodiment of the present invention. 12 is a conceptual view illustrating a battery detachment / attachment structure of a mobile terminal according to another embodiment of the present invention.

In the mobile terminal according to an embodiment of the present invention, a battery tray may be inserted into or withdrawn from the main body of the mobile terminal to replace the battery supplying the driving power.

The battery tray may be configured to receive a battery. For example, it may have an internal space to accommodate the battery. The battery tray may be formed to be inserted or withdrawn into one end of the main body of the mobile terminal in a sliding manner. For example, referring to FIGS. 11A and 11B, the mobile terminal may have a sliding part 130 formed to be inserted or withdrawn at a lower end of the main body in a sliding manner. The sliding portion 130 may be coupled to the battery body to form a uni-body.

The sliding unit 130 may further include an input / output port 119 for inserting an external cable and a microphone 122 for inputting an audio signal.

The sliding portion 130 may have a structure that can be inserted into or withdrawn from the lower end of the main body of the mobile terminal, as shown in FIG. 11C. Also, the sliding part 130 may be completely detached from the mobile terminal, but may have a structure for preventing the sliding part 130 from being separated from the mobile terminal.

11A to 11C, the main body and the battery can be attached and detached as the sliding portion 130 is drawn out from the main body. Accordingly, the power supply circuit can be in a first state in which power is not supplied from the battery.

11A to 11C, when the sliding portion 130 is inserted into the main body, the main body and the battery can be attached to each other. Thus, the power supply circuit can be in a second state in which power is supplied from the battery.

Meanwhile, as shown in FIG. 12, the mobile terminal according to another embodiment of the present invention may further include an inner space capable of receiving a battery in the rear case 102. In this case, the user can insert or withdraw the battery into the inner space formed on the rear surface of the mobile terminal.

For example, referring to FIG. 12, an inner space 1091 capable of receiving the battery 109 may be formed in the rear case 102 of the mobile terminal. Thus, the battery can be pulled into the internal space 1091 and attached to the main body, or drawn out from the internal space 1091, and can be detached from the main body.

In the above, the structure in which the battery is detachably attached to the mobile terminal according to the present invention has been described.

By attaching the battery to the main body, the booting can be performed automatically. Therefore, the present invention can start operating the operating system without any separate control command. Therefore, the present invention can lead to more natural use of the mobile terminal.

Also, since the battery can be attached to the main body and the operation of the operating system can be started, the boot time required for using the mobile terminal can be shortened.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
