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 or absence of an object approaching a predetermined detection surface or an object existing nearby without mechanical contact by using the force of an electromagnetic field or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal 100 covered by the touch screen described above or in the vicinity of the touch screen.

If the touch screen is a capacitive type, the proximity sensor 141 may be configured to detect the proximity of a conductive object as a change in electric field according to the proximity of the object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of description, an action of approaching a touch screen without contacting an object to recognize that the object is located on the touch screen is referred to as a "proximity touch", and the touch An act of actually touching an object on a screen is called a "contact touch". The location at which an object is proximity-touched on the touch screen means a location at which the object corresponds vertically to the touch screen when the object is proximity-touched. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.) have. Meanwhile, as described above, the controller 180 processes data (or information) corresponding to the proximity touch operation and proximity touch pattern detected through the proximity sensor 141, and furthermore, visual information corresponding to the processed data.

Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen, a stylus pen, or a pointer.

As such, 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 then transmits corresponding data to the controller 180. Thus, the controller 180 can know which area of the display unit 151 has been touched. Here, the touch controller may be a component separate from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different controls or the same control according to the type of the touch object that touches the touch screen (or a touch key provided other than the touch screen).

A photo sensor may be stacked on a display device, and the photo sensor is configured to scan a motion of a sensing object close to the touch screen. More specifically, the photo sensor scans the content placed on the photo sensor by mounting photo diodes and transistors (TRs) in rows/columns and using electrical signals that change according to the amount of light applied to the photo diodes. That is, the photo sensor calculates the coordinates of the sensing object according to the change in light, and through this, the location information of the sensing object can be obtained.

It is apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential characteristics of the present invention.

2A is a conceptual diagram for explaining a connection method between a terminal body and a charger according to the present invention.

As shown in FIG. 2A, the terminal body 100 related to the present invention can be connected to the charging device 200. As described above, the charging device 200 may include an AC adapter and/or an external battery that converts external AC power to DC power. That is, the charging device 200 according to the present invention may be of any type as long as it is connected to the mobile terminal and can supply power to the battery of the mobile terminal.

That is, the charging device 200 backs up at least a portion of data stored in the terminal body 100 connected to the charging device 200 in the memory 210 .

The terminal body 100 and the charging device 200 may be connected through any one of various connection methods to mutually transmit and receive data.

As an example, the terminal body 100 may be connected to the charging device 200 by wire through the interface unit 160 . More specifically, the terminal body 100 can be connected to the charging device 200 in a USB OTG (universal serial bus on-the-go) method. The terminal body 100 may perform appropriate control related to the connected charging device 200 in response to the connection of the charging device 200 to the interface unit 160 .

When the terminal body 100 and the charging device 200 communicate in a USB universal serial bus on-the-go (OTG) method, the terminal body 100 and the charging device 200 can perform high-speed communication and high-capacity communication. do.

As another example, the terminal body 100 may be wirelessly connected to the charging device 200 through a wireless communication unit. The terminal body 100 may transmit or receive data by being connected to the charging device 200 through short range communication using the short range communication module 114 . As described above, the short-range communication module 114 is for short-range communication, and includes Bluetooth™, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), and Ultra Wideband (UWB). ), ZigBee, NFC (Near Field Communication), Wi-Fi (Wireless-Fidelity), Wi-Fi Direct, and wireless USB (Wireless Universal Serial Bus) technologies may be used to support short-range communication. Such a short-range communication module may support wireless communication with the charging device 200 through wireless area networks. The local area wireless communication network may be a local area wireless personal area network (Wireless Personal Area Networks).

In this way, the terminal body 100 may be connected to the charging device 200 by wire or wirelessly. Meanwhile, the charging device 200 related to the present invention may receive authentication information (or identification information) from the terminal body 100 connected by wire or wirelessly.

Here, the authentication information or identification information of the terminal body 100 is unique information possessed by the connected terminal body 100, and information by which the connected terminal body 100 can be identified by the charging device 200. can be This authentication information may include at least one of PID (Product Identification) information, SSID (Service Set Identifier, SSID) information, access security method information, and password.

In the charging device 200, when the backup function is performed, the terminal body 100 to back up data may be specified or registered in advance. That is, the charging device 200 may be set to perform a backup function only with the pre-registered terminal body 100 .

In this case, when connected to the unregistered terminal body 100, notification information related to registration may be output. The notification information may be output in various ways. The notification information may be output using at least one of auditory, tactile and visual methods.

Meanwhile, in the present invention, as described above, when the pre-registered terminal body 100 is connected to the charging device 200, the data stored in the terminal body 100 is transmitted to the charging device 200, thereby transmitting the transmission The data may be stored in the charging device 200. That is, all or part of data stored in the terminal body 100 may be stored in the charging device 200 .

Meanwhile, in the present invention, data to be stored in the charging device 200 among data stored in the terminal body 100 may be determined based on a user's selection or under the control of the control unit 218.

Here, the controller 218 may mean one of the controller 180 of the terminal body 100 and the controller 218 of the charging device 200 .

The control unit 218 determines the type (or format) of data, the application associated with the data, the data creation date, the data storage date, the data modification (or modification) date, and whether or not the data has already been stored in the charging device 200. Data to be backed up among data stored in the memory 170 of the terminal body 100 may be determined based on various criteria such as the like.

Figure 2b is a conceptual diagram for explaining the components of the charging device according to an embodiment of the present invention.

The charging device 200 according to this embodiment includes a controller 218 including a host chip for data transmission. The charging device 200 includes a charging unit 201 that implements different connection modes to perform a charging function and a backup unit 202 that receives data and stores them in a memory () or a predetermined specific server.

However, the backup unit 202 refers to a circuit that performs a data reception function while connected in a connection mode capable of data transmission, and the charging unit 201 is a circuit that performs a function of supplying power in a specific connection mode. means

The charging device 200 according to an embodiment of the present invention may further include a memory 207 for storing received data and/or a wireless communication module 209 for transmitting data by performing wireless communication with a specific server. have.

The memory 207 may be a flash memory type, a hard disk type, a solid state disk type, a silicon disk drive type, or a multimedia card micro type. type), card-type memory (eg SD or XD memory, etc.), RAM (random access memory; RAM), SRAM (static random access memory), ROM (read-only memory; ROM), EEPROM (electrically erasable programmable read-only memory), programmable read-only memory (PROM), magnetic memory, magnetic disk, and optical disk.

Figure 3a is a conceptual diagram for explaining a control method of a charging device according to an embodiment of the present invention. 3B is a conceptual diagram for explaining a connection mode according to an embodiment.

Referring to FIG. 3A , when the charging device 200 is connected to the main body of the mobile terminal 100 (S201), the first connection mode is activated for a specific time and the charging function is executed (S202). In the first connection mode, the control unit 218 connects the charging device 200 and the mobile terminal body 100 in a DCP manner.

In the DCP (Dedicated Charging Port) method, D+ and D- are shorted to block data communication, and about 1.5A of power is supplied to the mobile terminal body 100. In the connection mode of the DCP method, the mobile terminal 100 is charged at a relatively high speed.

Here, the specific time is determined by the user's setting, or depends on the capacity of the battery built in the mobile terminal 100, the existence of data stored in the memory 170 of the mobile terminal 100 and requiring backup, and the storage capacity. can be determined by Here, data requiring backup may correspond to data that has not been previously received by the charging device 200 or newly stored after being recently backed up by the charging device 200 .

When the specific time elapses, the control unit 218 changes the first connection mode to a second or third connection mode, and examines whether data requiring backup exists (S203). Here, the second connection mode corresponds to a state in which the charging device 200 and the mobile terminal body 100 are connected by the SDP method, and the third connection mode corresponds to a state in which the charging device 200 and the mobile terminal body ( 100) in the CDP method.

The SDP (Standard Downstream Port) method supplies power at a maximum speed of about 500 mA/s while performing data communication, and the CDP (Charging Downstream Port) method supplies power of up to about 1.5 A while performing data communication. applicable to the method.

The controller 218 determines whether data is received from the mobile terminal 100 in the second connection mode or the third connection mode (S203). When data is received from the mobile terminal 100 in the second or third connection mode, the data backup function is executed while maintaining the second or third connection mode (S204).

In this embodiment, the charging device 200 transmits a transmission request command requesting transmission of data to the mobile terminal 100 as a host. therefore,

When data is not received from the mobile terminal 100 in the second or third connection mode, the control unit 218 connects in the DCP method and executes a charging function (S205). That is, when there is no data to be backed up, the controller 218 can change from the second or third connection mode to the first connection mode, cut off data communication, and perform a high-speed charging function.

Since the control unit 218 can perform both a charging function and a backup function while the mobile terminal main body 100 and the charging device 200 are connected, the user can use the mobile terminal 100 or the charging device 200 separately. Even if the control command for the backup function is not applied, data backup can be performed only by connection for charging. Therefore, the user can back up data at any time.

In addition, the high-speed charging function is performed for a specific time and the first to third connection modes are alternately activated based on the presence or absence of data to be backed up, so that power is supplied to the mobile terminal while low-speed charging and data data are supplied if necessary. can back up.

3B is a conceptual diagram for explaining the connection structure of the DCP method, the SDP method, and the CDP method.

In the DCP method, D+ and D- are shorted and data communication is blocked, and data reception is impossible. A connected device can recognize the SDP by detecting that a 15 kΩ pull-down resistor is connected to both the USB data lines and the D+ and D- terminals.

The DCP method provides up to 1.5A of power and includes a pull-down resistor of up to 15kΩ required for communication between D+ and D-. A device connected to CDP detects CDP by means of hardware through adjustment and monitoring of D+ and D- lines. Testing of this hardware is done prior to tuning of the data lines through the USB transceiver. DCP includes an internal circuit that is switched in the charge detection step, and a connected terminal can be distinguished from other CDP schemes by the internal circuit.

Figure 4a is a conceptual diagram for explaining a control method of a charging device according to another embodiment.

Referring to FIG. 4A , when the body of the mobile terminal 100 is connected to the charging device 200 (S211), the first connection mode is activated (S212). In the first connection mode, the mobile terminal and the charging station are connected in a DCP manner to perform a high-speed charging function.

The control unit 218 determines whether charging of the battery of the mobile terminal 100 is completed after a specific time has elapsed (S213). Whether or not the charging is completed can be determined based on the elapsed time during which the charging function was performed or the amount of power information output from a measuring sensor installed in the charging device 200 or the mobile terminal 100 to measure the amount of power.

If it is determined that the charging is not completed, the control unit 218 continues to perform the charging function by maintaining the first connection mode (S214). Meanwhile, when it is determined that charging is completed, the controller 218 determines whether the connected mobile terminal 100 supports the CDP method (S215). That is, it can be determined by whether the mobile terminal 100 recognizes the connection of the CDP method.

When it is determined that the mobile terminal does not support the CDP method, the control unit 218 switches to the third connection mode. In the third connection mode, the charging device 200 and the mobile terminal are connected in the SDP method.

However, when the connected mobile terminal supports the CDP method, the controller 218 switches to the second connection mode. In the second connection mode, the charging device 200 and the mobile terminal are connected using the CDP method (S217).

In the second connection mode or the third connection mode, the controller 218 determines whether newly updated data exists (S218).

When the newly updated data exists, the controller 218 receives the data from the mobile terminal 100 and performs a backup function. A charging function is performed at a low speed while receiving the data in the second connection mode.

When the newly updated data does not exist, the controller 218 converts the second connection mode or the third connection mode to the first connection mode. When the first connection mode is activated, data communication is blocked and only a charging function is performed.

According to the present embodiment, it is first determined whether or not the CDP method connection, which has a relatively fast charging speed, is supported, and only when it is not supported, the SDP method is connected. Accordingly, the battery of the mobile terminal can be discharged at a higher speed while performing data communication as much as possible.

In addition, when the backup function is not required, faster charging can be induced by switching to the DCP method.

Figure 4b is a conceptual diagram for explaining a control method of a charging device according to another embodiment.

Referring to FIG. 4B , when the body of the mobile terminal 100 is connected to the charging device 200 (S221), the controller 218 activates the third connection mode (S222). Since the mobile terminal and the charging device 200 are connected using the SDP method in the third connection mode, data communication is possible. Since the low-speed charging function is available in the third connection mode, the mobile terminal 100 can receive power when the charging device 200 is connected.

Since most terminal devices support the SDP scheme, it is unnecessary to check whether SDP is supported. Therefore, charging is possible at the same time as the charging device 200 is connected.

Also, as soon as the mobile terminal 100 is connected, the control unit 218 can check whether updated new data exists (S223). When it is determined that there is no updated new data, the controller 218 converts the third connection mode to the first connection mode (S229).

In the first connection mode, a high-speed charging function can be performed through the DCP method. That is, when the backup function is unnecessary, the data communication function may be blocked and fast charging may be performed.

Meanwhile, the control unit 218 determines whether the connected mobile terminal supports the CDP method when there is new updated data (S224). The controller 218 switches to the second connection mode when the mobile terminal supports the CDP scheme (S225), and maintains the third connection mode when the mobile terminal does not support the CDP scheme (S226).

The control unit 218 performs a backup function through data communication while performing a charging function at a low speed in the second connection mode or the third connection mode (S227). When the backup of the data stored in the mobile terminal 100 is completed (S228), the controller 218 converts the second or third connection mode to the first connection mode. That is, when the backup is completed, the control unit 218 connects again in the DCP method and performs the charging function at high speed.

According to this embodiment, as soon as the mobile terminal is connected to the charging device 200 by using the SDP method applicable regardless of the type of terminal, it is possible to check whether the backup function is necessary while immediately supplying power.

Accordingly, the user preferentially performs data backup along with low-power charging depending on whether the backup function is necessary, and when the backup is completed, the user switches to the first connection mode, so it is possible to switch to high-speed charging without a separate control command.

5A and 5B are conceptual diagrams for explaining a control method of changing execution times of a backup function and a charging function.

Referring to FIGS. 5A and 5B , when the charging device 200 and the mobile terminal are connected (S231), the controller 218 activates the first connection mode (S232). That is, the mobile terminal and the charging device 200 are connected in a DCP method to perform a high-speed charging function (S232).

The controller 218 performs the charging function according to the DCP method for the first predetermined time period (t1) (S233). The first time t1 may be set as a time for charging minimum power for performing basic functions in a power-on state in a state in which the battery of the mobile terminal 100 is completely discharged, but is limited thereto. it is not going to be

The controller 218 maintains the charging function when the first time period t1 has not elapsed (S224). When the first time t1 elapses, the control unit 218 checks whether the connected mobile terminal 100 supports the CDP method (S235). The control unit 218 converts the first connection mode to the second connection mode when the mobile terminal 100 supports the CDP method (S236), and when the mobile terminal does not support the CDP method , the third connection modules are activated and connected in the SDP method (S237).

The control unit 218 checks whether newly updated data exists in the second or third connection mode (S238), and executes a backup function to back up the newly updated data if it exists (S239). . The controller 218 executes the backup function for a second time t2, and the second time t2 may be a time during which only a part of data to be backed up can be backed up.

When the second time period t2 elapses (S240), the controller 218 converts the second or third connection mode into the first connection mode. In the first connection mode, the control unit 218 cuts off data communication through the DCP method and performs a charging function.

Referring to FIG. 5B, when the mode is switched back to the first connection mode, the controller 218 performs the charging function for a decelerated first time period (t1') and the backup function for an increased second time period (t2'). Do it. The sum of the first and second times t1 and t2 and the changed sum of the first and second times t1' and t2' are set equal to each other. However, in order to maintain a stable charging state of the mobile terminal, the first time period t2 is preferably set longer than the second time period t2. .

That is, while the charging function and the backup function are repeated, the first time during which the charging function is performed is continuously shortened, and the second time during which the backup function is performed is continuously increased. It is possible to secure time to back up a large amount of data by performing a backup function while maintaining a stable state of charge and spending more time on the backup function as the battery charge progresses.

The charging function and the backup function are performed repeatedly until charging is completed or data backup is completed. That is, when the data backup is completed, the controller 218 maintains only the first connection mode, and when the charging is completed, the controller 218 maintains only the second or second connection mode.

If there is no newly updated data, the charging function is performed in the DCP method by switching to the first connection mode (S244a). When newly updated data exists, the first connection mode is activated for a first variable time period t1.

The controller 218 performs the charging function in the DCP method during the first variable time period t1 (S244b). When the first variable time t1 elapses (S246), it is determined whether the connected mobile terminal 100 supports the CDP method (S247).

The controller 218 activates the second connection mode when the mobile terminal 100 supports the CDP method (S248), and activates the third connection mode when the CDP method is not supported (S249). The control unit 218 executes a backup function and a charging function in the CDP method or the SDP method respectively in the first and second connection modes (S249).

The control unit 218 performs the backup function and the charging function during the second variable time period t2 (S250), and when the second variable time period t2 elapses, switches back to the first connection mode and only the charging function. carry out

Here, the first and second variable times t1 and t2 are not fixed and may be changed based on the remaining amount of power charged and the backup state of data. Repetitive activation of the first connection mode and the second or third connection mode is repeated until charging is completed or backup is completed.
