For the sensing, the first body 210 includes a magnet 245 on one surface facing the mobile terminal 100, and on the rear side of the mobile terminal, the body of the mobile terminal is the first When coupled to the body, a hall sensor 143 formed to sense a magnetic field corresponding to the magnet 245 may be included. When the magnetic field is sensed by the hall sensor, the mobile terminal may recognize that it is coupled to the case and perform preset control.

Here, the preset control does not mean the supply of the operating current as described above.

When the first and second wired communication units 161 and 234 are connected to enable mutual communication, the mobile terminal 100 includes a plurality of contacts included in the first wired communication unit 243 provided in the first body 210 . A plurality of resistors Ra and Rd formed in the first body 210 may be recognized through specific contact pins (eg, CC1 and CC2) among the pins. When the plurality of resistors are recognized in this way, an operating current is supplied to the second display 250 by supplying the power, for example, Vconn to CC1 .

When the operating current is supplied to the second display 250 , the system of the second display 250 is booted up and initialized to enter an operable standby state.

In this case, the second display 250 has any one of an active state and an inactive state, and even in a state in which the second display 250 is inactive, a touch sensor (or a touch panel) provided in the second display 250 . 252 may be driven in an activated state to sense a touch applied to the second display 250 .

In this case, the digital image signal may be converted into a form that can be output by the second display 250 through the data converter 282 . For example, the second display 250 may be configured as an LCD panel, and in this case, the DP format digital image signal received from the mobile terminal 100 is received by the LCD panel through the data conversion unit 282 . It may be converted into a possible data format (MIPI format), and transmitted and output to the screen 251 .

Meanwhile, data transmitted/received through the first and second wired communication units 161 and 243 may be transmitted/received using different contact pins in the USB I/O interface depending on the type.

Specifically, for example, an image signal may be transmitted/received from the mobile terminal 100 to the second display 250 through the USB SSPHY pin, and output from the second display 250 through the data conversion unit 282 . It can be converted into a possible format (eg, MIPI format format). Also, for example, a control signal related to the operation of the second display 250 may be transmitted/received to and from the second display 250 through an external display port (EDP) AUX pin.

Signals required to be transmitted between the mobile terminal 100 and the display 250, such as a communication control signal, a touch signal, and a brightness control signal, are first and second signal processing units using the second USB HID (Human Interface Device) communication. Through (181, 281), it is possible to transmit and receive.

At this time, in the initial state of the mobile terminal 100, the first signal processing unit 181 transmits and receives signals through the first USB communication using the A-side A6 and A7 pins and the B-side B6 and B7 pins of the connector. On the other hand, when the first and second wired communication units 161 and 234 are connected to be able to communicate with each other, and a plurality of resistors Ra and Rd are recognized through the CC1 pin, they are switched through a switch, and A used in the initial state The side pins and the B side pins are separated, and a signal is transmitted and received using the second USB communication using only the B6 and B7 pins of the B side.

As such, when the switch is switched to perform signal processing using the second USB communication, the first and second signal processing units 181 and 281 perform I2c conversion to USB HID (Human Interface Device) communication, and the second An operation corresponding to a touch applied to the display 250, for example, transmission of a touch signal corresponding to the touch, may be performed. In addition, the first and second signal processing units 181 and 281 may support HPD (Hot Plug Detect) communication between the control unit 280 and the data conversion unit 282 through the second USB communication.

Meanwhile, initialization of the second display 250 may be controlled by the controller 280 included in the second display 250 .

As described above, the mobile terminal according to the embodiment may control information output to the display 250 provided in the case 200 . That is, the driving of the second display 250 may be controlled by the mobile terminal 100 . To this end, the connection port of the mobile terminal and the connector provided in the case 200 are connected, and by recognizing a plurality of resistors, the case 200 to which the mobile terminal is coupled can be identified. Accordingly, in the present invention, since there is no need to provide a separate chip for communication between the mobile terminal and the case 200 , it is compatible with various models of mobile terminals, and the cost can be saved. The thickness also becomes thinner.

Hereinafter, a control method between a mobile terminal and a display provided in the case will be described in more detail with reference to the accompanying drawings, based on the above. 5 is a representative flowchart for explaining a control method between a mobile terminal and a display provided in a case in an electronic device according to an embodiment.

As described above, in the electronic device 300 according to the embodiment, when the mobile terminal 100 is coupled to the case 200 , the mobile terminal 100 may sense a resistance corresponding to the second display 250 . There is (510).

Specifically, when the connection port of the mobile terminal 100 is connected to a connector provided on one side of the case 200 , the mobile terminal 100 determines whether to supply an operating current to the second display 250 . For this purpose, a plurality of resistors provided together with the connector may be recognized.

When the plurality of resistors are recognized, an operating current is supplied from the mobile terminal 100 to the second display 250 through the connector, and the second display 250 may maintain driving in an inactive state (520). ).

Specifically, when the plurality of resistors are recognized, the mobile terminal 100 operates in a host mode and supplies the operating current to the connector downstream. That is, the connection port of the mobile terminal 100 is switched to become a Downstran Host Mode Facing Port (DFP), and supplies an operating current to the contact pin. For example, an operating current is supplied in the form of a Vconn power supply through a CC1 pin among the contact pins of the connector.

In this case, the second display 250 on the case 200 side operates in the device mode and receives the operating current upstream. That is, the connector of the case 200 operates as an Upstream Facing Port (UFP).

As described above, the operating current supplied through the CC1 pin of the connector is transferred to the circuit board ( 244), etc. In addition, the operating current is also supplied to the power supply 291 of the second display 250 .

Meanwhile, as described above, the electronic device 300 may be in any one of an open state and a closed state, and when a transition from the closed state to the open state is detected, the first display provided in the mobile terminal At 151 , driving may be maintained in an activated state ( 530 ). In this case, the detection of the transition from the closed state to the open state may be performed, for example, by recognizing a value sensed by an illuminance sensor provided on the front surface of the mobile terminal 100 .

Alternatively, when the electronic device 300 is opened, the connection port of the mobile terminal 100 is connected to a connector provided on one side of the case 200 , and the first display 151 of the mobile terminal 100 is ) or when an input is applied to the user input unit 123 , the first display 151 may maintain operation in an activated state.

As such, when a preset touch input is applied to the first display 151 while the second display 250 in the inactive state is maintained, the mobile terminal detects the touch (540), and responds to the detected touch. A touch signal is determined ( 550 ).

As a result of the determination, if the touch signal is for switching the second display 250 to the activated state, the controller of the mobile terminal may output a control signal for switching the second display 250 to the activated state (560).

As another example, when the first display 151 provided in the mobile terminal is driven in an activated state as the electronic device 300 detects a transition from the closed state to the open state, a predetermined time (eg, , 0.5 seconds to 1 second), the second display 250 may be switched from an inactive state to an active state and driven. That is, after the screen of the first display 151 is turned on, the screen of the second display 250 may be turned on after a predetermined time.

In this case, the above-described steps 540 and 550 are omitted and whether the electronic device 300 is switched from the closed state to the open state before the operation 530 of driving the first display 151 in the activated state is performed. A step of detecting may be added.

Meanwhile, as another example, although not shown, when a preset touch input is applied to the second display 250 while the second display 250 is driven in an inactive state, based on this, the second display ( A control signal for switching 250 ) to an active state may be transmitted from the mobile terminal 100 .

In this case, the signal processing corresponding to the touch signal sensed by the second display 250 may be performed by the first and second signal processing units 181 and 281 as described above.

Specifically, in the initial state of the mobile terminal 100 , while performing wired communication using the first USB communication, a plurality of resistors Ra and Rd corresponding to the second display 250 are connected to the connector of the case 200 . When this is recognized, the mobile terminal 100 controls the operation corresponding to the touch using the second USB communication connected only with the B-side contact pins (eg, B6, B7).

Even in a state in which the second display 250 is deactivated, the touch sensor (or touch panel, 252 ) provided in the second display 250 is driven in an activated state to sense a touch applied to the second display 250 . can do.

The sensed touch may be converted into I2c through the first and second signal processing units 181 and 281 . In addition, the sensed touch includes a circuit board 244 provided on the second body of the case, a wiring unit 242 coupled to the first and second flexible circuit boards 247 and 248 , and a connector, that is, a second wired communication unit. Through 243 , it is transmitted from the second display 250 to the mobile terminal 100 .

Then, the mobile terminal 100 determines the touch signal transmitted from the second display 250 as described above, and determines whether it corresponds to a preset touch input. Here, the preset touch input may mean, for example, applying a plurality of tabs to the second display 250 in an inactive state.

When it is determined that the touch input corresponds to the preset touch input, the mobile terminal 100 may perform the above-described process of step 560 . That is, a control signal for switching the second display 250 to the activated state may be output by the controller of the mobile terminal 100 and transmitted to the second display 250 .

Thereafter, the mobile terminal 100 may transmit an image signal corresponding to the screen to be output to the second display 250 through USB communication ( 570 ).

To this end, the first and second wired communication units 161 and 243 transmit, for example, a DP type image signal through a USB SS PHY pin.
