Meanwhile, the sensing unit 140 senses at least one of information in the mobile terminal, information on a surrounding environment surrounding the mobile terminal, and user information, and generates a sensing signal corresponding thereto. The controller 180 may control the driving or operation of the mobile terminal 100 or perform data processing, functions, or operations related to an application program installed in the mobile terminal 100 based on such a sensing signal. 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 in the vicinity using the force of an electromagnetic field or infrared rays without mechanical contact. In the proximity sensor 141, the proximity sensor 141 may be disposed in an inner area of the mobile terminal surrounded by the touch screen as described above or near the touch screen.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive type proximity sensor, a magnetic type proximity sensor, an infrared proximity sensor, and the like. When the touch screen is a capacitive type, the proximity sensor 141 may be configured to detect the proximity of the object by a change in the electric field according to the proximity of the conductive 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 explanation, the action of allowing an object to be recognized as being positioned on the touch screen by being approached without contacting an object on the touch screen is called "proximity touch", and the touch The act of actually touching an object on the screen is referred to as "contact touch". A position at which an object is touched in proximity on the touch screen means a position at which the object is vertically corresponding to the touch screen when the object is touched in proximity. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (for example, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, a proximity touch movement state, etc.). have. Meanwhile, as above, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141, and further, provides visual information corresponding to the processed data. It can be output on the touch screen. Furthermore, the controller 180 may control the mobile terminal 100 so that different operations or data (or information) are processed according to whether a touch to the same point on the touch screen is a proximity touch or a touch touch. .

The touch sensor is a touch (or touch input) applied to the touch screen (or the first display unit 151) using at least one of various touch methods such as a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method. ).

As an example, the touch sensor may be configured to convert a pressure applied to a specific portion of the touch screen or a change in capacitance generated at a specific portion into an electrical input signal. The touch sensor may be configured to detect a location, an area, a pressure upon touch, a capacitance upon touch, and the like at which a touch object applying a touch on the touch screen is touched on the touch sensor. 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.

In this way, when there is a touch input to the touch sensor, the signal(s) corresponding thereto is transmitted to the touch controller. The touch controller processes the signal(s) and then transmits the corresponding data to the controller 180. Accordingly, the controller 180 can know which area of the first display unit 151 has been touched. Here, the touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

The mobile terminal 100 includes an illuminance sensor 142 configured to sense ambient illuminance, and the controller 180 of the mobile terminal 100 is in a state in which the cover is closed according to the illuminance sensed through the illuminance sensor. And the open state can be sensed. Furthermore, the controller 180 may separately detect a fully open state among the open states.

Meanwhile, the controller 180 may perform different controls or perform the same control according to the type of the touch object by touching the touch screen (or a touch key provided in addition to 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 an operating state of the mobile terminal 100 or an application program being executed.

Meanwhile, the touch sensor and the proximity sensor described above are independently or in combination, and a short (or tap) touch, a long touch, a multi touch, and a drag touch on the touch screen. ), flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, etc. You can sense the touch.

The ultrasonic sensor may recognize location information of a sensing target by using ultrasonic waves. Meanwhile, the controller 180 may calculate the location of the wave generator through information sensed from the optical sensor and the plurality of ultrasonic sensors. The location of the wave generator may be calculated by using a property that the light is much faster than the ultrasonic wave, that is, the time that the light reaches the optical sensor is much faster than the time that the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generator may be calculated using a time difference between a time when the ultrasonic wave arrives using light as a reference signal.

On the other hand, the camera 121, viewed as the configuration of the input unit 120, includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to detect a touch of a sensing target for a 3D stereoscopic image. The photosensor may be stacked on the display device, and the photosensor is configured to scan a motion of a sensing object close to the touch screen. More specifically, the photo sensor scans the contents placed on the photo sensor by mounting a photo diode and a transistor (TR) in a row/column and using an electrical signal that changes according to the amount of light applied to the photo diode. That is, the photosensor calculates the coordinates of the sensing target according to the amount of light change, and through this, the location information of the sensing target may be obtained.

The first display unit 151 displays (outputs) information processed by the mobile terminal 100.

There is a problem in that the second display unit 251 of the terminal 100 and the second display unit 251 of the display device 200 cannot be viewed at the same time.

The mobile terminal 100 is mounted on the second area 272 of the display apparatus 200 of the present invention, and the two second display units 251 are arranged side by side as shown in FIG. 1 to be used as a dual display.

When using as a dual display, a screen is moved from the second display unit 251 of the mobile terminal 100 to the second display unit 251 of the display device 200 by touching and dragging, or a list including a plurality of items Is output on the list of the mobile terminal 100 and content corresponding to the selected item may be output on the second display unit 251 of the display apparatus 200.

When the second display unit 251 of the display apparatus 200 is larger than the first display unit 151 of the mobile terminal 100, the second display unit 251 of the display apparatus 200 can be used as the main display unit. Thus, the second display unit 251 of the display apparatus 200 may be controlled.

Only one of the two

display units

151 and 251 may be selectively activated, or a screen of the display apparatus 200 may be activated through the user input unit 220 of the mobile terminal 100.

The second area 272 is divided into two areas, as shown in FIG. 3A, which is a second area to position the third area 273 in front of the second display unit 251 as shown in FIG. 5A. 272) can be divided into two areas and arranged to overlap.

The second display unit 251 may include a display panel on which a screen is output and a rear bracket 2512 positioned on a rear surface of the display panel.

The display panel is a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), and a flexible display ( flexible display), a 3D display, and an e-ink display.

The rear bracket 2512 prevents the display device 200 from being damaged by an external force, and the variable portion 271b and the fixing portion 271c of the case 270 are separated from the rear surface of the second display unit 251. Therefore, it covers the back of the display panel so that it is not exposed to the outside. However, since the first part of the second display unit 251 fastened with the coupling part 271a is not exposed to the outside, the printed circuit board 281 or various parts are arranged as the control unit 280 on the coupling part 271a. Can be. An opening 2513 may be formed to arrange the printed circuit board 281 or the like.

The controller 280 of the display apparatus 200 controls the second display unit 251 through the first interface unit 261 according to the control of the controller 180 of the mobile terminal 100. In addition, power input through the first interface unit 261 is supplied to the second display unit 251, and signals input through the user input unit 220 such as a touch sensor are moved through the first interface unit 261 It can also be transmitted to the terminal 100.

A flexible substrate 282a connecting the first interface unit 261 and the printed circuit board 281 and a flexible substrate 282b connecting the printed circuit board 281 and the second display unit 251 may be included. . The flexible substrate 282b may be extended from an end of the display panel and bent toward a rear surface of the display panel to be connected to the printed circuit board 281.

In addition to the first interface unit 261 connected to the mobile terminal 100, a second interface unit 262 in the form of a cable terminal connected through a cable may be further included. Used to connect to the mobile terminal 100 that does not have the first interface unit 261 located in the second area 272 and the interface unit 160 connectable, or another mobile terminal 100 through a cable terminal It can be connected to or supplied with power.

FIG. 5B shows a second state of the display apparatus 200. In the first state of FIG. 3B, the folding part 277 of the second area 272 is folded so that the two areas of the second area 272 overlap. And the arrangement of the cover part of the display apparatus 200 may be changed so that one surface of the third area 273 covers the front surface of the second display unit 251. The second state can protect the second display unit 251 in a situation where the display device 200 is not used and is carried. In the second state, the other surface of the case 270 is exposed to the outside.

5B shows a third state of the display device 200. In the first state, the folding part 277 between the third area 273 and the second area 272 is bent so that the other surface of the third area 273 becomes the other surface of the second area 272 and the first area 271. It can be placed in contact with the other surface of the device to switch to the third state. At this time, since the second area 272 is positioned parallel to the second display unit 251, the second display unit 251 is exposed to the outside while the mobile terminal 100 is connected to the first interface unit 261. I can. In the first state, the space occupied by the third area 273 is large and portability is poor. Accordingly, in order to increase portability and increase space utilization, the third area 273 may be disposed to overlap the first area 271 and the second area 272 in a third state.

In the second state (FIG. 5A) and the third state (FIG. 5B), the third area 273 is stably fixed, and the variable part 271b and the fixed part 271c of the first area 271 are the second display unit. A magnet may be provided on the back of 251 to prevent separation from the user in an unintended situation.

6 is a perspective view showing a fourth state and a fifth state of the display device 200 related to the present invention. When the fixing part 271c is combined with a specific portion of the third area 273 and the third area 273 is placed on the mounting surface, the second display unit 251 can be mounted while being erected at a predetermined angle. In this case, the angle formed between the second display unit 251 and the mounting surface may vary according to the position and direction of the coupling between the fixing unit 271c and the third area 273.

As in the fourth and fifth states, a magnet may be used to fix the fixing part 271c to the third region 273. A magnet for fixing the fixing part 271c and the variable part 271b to the rear surface of the second display unit 251, a magnet for fixing the third area 273 to the front or rear surface of the second display unit 251, and A magnet for fixing the fixing part 271c of FIG. 8 to the third area 273 may be provided separately, but depending on the state of the display device 200, one magnet is combined with another magnet to provide the display device 200. Can maintain the state of.

7 is a diagram illustrating a cover part and a rear bracket 2512 of a display apparatus 200 related to the present invention, and a rear case 270 of a mobile terminal 100 related to the present invention.

The first magnet 2301 located on the variable part 271b of the first area 271 and the second magnet 2302 of the fixing part 271c are located on the rear bracket 2512 of the second display unit 251 In combination with the third magnet 2303 and the fourth magnet 2304, the variable part 271b and the fixed part 271c are not separated on the rear surface of the display device 200 in the first and second states. Provides a bonding force to be fixed. That is, the first magnet 2301 and the third magnet 2303 are coupled, and the second magnet 2302 and the fourth magnet 2304 are coupled to maintain the first state.

A plurality of first to fourth magnets 2301 to 2304 may be divided and disposed in a second direction perpendicular to the first direction (vertical direction in the drawing) in order to secure a coupling force.

In the second state as shown in FIG. 5A, a fifth magnet 2305 may be further included so that the third area 273 is fixed to the front surface of the second display unit 251. The fifth magnet 2305 positioned in the third area 273 may maintain the second state by providing a force that engages the fourth magnet 2304 of the second display unit 251 described above. Since the fifth magnet 2305 and the fourth magnet 2304 may be insufficient to fix the third region 273, a sixth magnet may be further provided at a position spaced apart from the fourth magnet 2304, and the third The region 273 may further include a seventh magnet 2307 to assist in maintaining the second state by combining with the sixth magnet 2306 in the second state.

In the third state as shown in FIG. 5B, the third region is coupled to the other surface of the first region 271 and the second region 272. Unlike the second state, since the folded portion is between the second region 272 and the third region 273, the end of the third region 273 does not touch the end of the first region 271. Therefore, the fifth magnet 2305 may further include an eighth magnet in the first region 271 to which the fifth magnet 2305 can be coupled so that the fifth magnet 2305 can be maintained in a third state without contacting the second magnet 2302. .

A magnet to be coupled with the second magnet 2302 positioned at the fixing part 271c to erect and mount the second display part 251 as shown in FIGS. 6A to 6C is in the third area 273. It can be provided. In this case, the magnet of the third region 273 coupled with the second magnet 2302 may use the fifth magnet 2305 for coupling with the front surface of the second display unit 251 described above.

When the fifth magnet 2305 and the second magnet 2302 are coupled, the third region 273, the coupling portion 271a, and the variable portion 271b form a triangle and support the second display unit 251 while supporting the fourth. You can keep the state. As shown in (a) of FIG. 6, one surface of the fixing part 271c may be arranged to abut the other surface of the third region 273, and the other surface of the fixing part 271c may contact the other surface of the third region 273. Can be placed. That is, in the fourth state, the second display unit 251 may be mounted at different angles depending on the surface to which the fixing unit 271c is coupled. (θ1< θ2)

In addition, a ninth magnet 2309 positioned closer to the second region 272 than the fifth magnet 2305 may be further provided in order to more steeply mount the mounting angle of the second display unit 251. 6C shows a fifth state in which the ninth magnet and the second magnet 2302 are coupled. The second display unit 251 may be mounted at a larger angle than when the second magnet 2302 is coupled to the fifth magnet 2305.

When the ninth magnet 2309 and the fifth magnet 2305 are spaced apart by a distance between the first magnet 2301 and the second magnet 2302, the ninth magnet 2309 is removed in the second state. 2 Since the display unit 251 overlaps with the third magnet 2303, it may be combined with the third magnet 2303.

In addition, a tenth magnet that can be coupled with the ninth magnet 2309 may be further included to reinforce a force that the third region 273 is fixed to the first region 271 in the third state. The tenth magnet 2310 may be located in the coupling portion 271a, and since the printed circuit board 281 or the flexible substrate 281 is disposed on the coupling portion 271a, it may be difficult to secure an appropriate space. As shown in (a), it is provided only on one side and instead can be formed to be larger in size. The ninth magnet 2309 coupled with the tenth magnet may have a larger size accordingly.

Fixed to fix the mobile terminal 100 in the second area 272 so that the first interface unit 261 of the mobile terminal 100 can maintain a connection state with the first interface unit 261 of the display device 200 To do this, an eleventh magnet may be further provided in the second region 272. The terminal 100 and the magnet 105 corresponding to the eleventh magnet may be provided on the rear cover 103 of the mobile terminal 100. The first portion and the second portion of the second region 272 are divided into a folding portion 277, and a pair of the eleventh magnets 2311 may be provided in the first portion and the second portion. However, in the second state of FIG. 5A, when the first part and the second part are disposed to overlap, the pair of eleventh magnets should be disposed so that different poles are located on the same side so that repulsion is not generated.

8 is a view showing one side (270a) and the other side (270b) of the case 270 of the present invention, Figure 10 is a view showing the other side (2512b) and one side (2512a) of the rear bracket (2512) of the present invention. It is a drawing. FIG. 8A shows one surface 270a of the case, and FIG. 8B shows the other surface 270b of the case. FIG. 11(a) is a view showing the other surface 2512b of the rear bracket facing FIG. 8(a), and FIG. 9(b) is a view showing one surface 2512a of the rear bracket.

FIG. 8(b) is a view showing a state in which FIG. 8(a) is turned upside down, and FIG. 9(b) is a view showing a state in which FIG. 9(a) is turned upside down, and The position of the direction has changed.

Since magnets have different poles (N pole or S pole) on both sides, if one magnet is used, the poles of one side and the other side have different polarities. For convenience of explanation, the description is based on a case where the direction of one side of the first magnet 2301 is called the S-pole 2301s and the direction of the other side is the N-pole 2301n. However, the N-pole in the direction of one side of the first magnet 2301 The S-pole can be located in the direction of the other surface. When the polarity of the first magnet 2301 is changed, other poles may have opposite poles.

However, in order for both the one side and the other side of the fixing part 271c to be combined with the fifth magnet 2305 as shown in FIGS. 6A and 6B, the second magnet 2302 is provided on both one side and the other side. They must have the same polarity. For example, if the second magnet 2302 has N poles 2302n on one side and the other side, the fifth magnet 2305 and the ninth magnet 2309 are arranged so that the

S poles

2305s and 2309s are directed to the other side. I can. In the second state, in order for one surface 2305n of the fifth magnet to be coupled with the fourth magnet 2304 of the rear bracket 2512, one surface 2304s of the fourth magnet (FIG. 8(a)) must be S-pole.

The fourth magnet 2304 is coupled with the second magnet 2302 of the fixing part 271c, and since one side of the second magnet 2302 is the N-pole, the other side 2304s of the fourth magnet, FIG. 8(b), is also S It should be a play. Therefore, the fourth magnet 2304 also has the same pole on one side and the other side.

In order to make a magnet with the same polarity on one side and the other side, such as the second magnet 2302 and the fourth magnet 2304, as shown in Fig. 9(a), two permanent magnets and a shielding plate therebetween are interposed. Both sides can have the same pole. The fourth magnet 2304 is disposed so that the N poles face each other in order to make both sides of the S pole, and a shield plate is interposed therebetween to cancel the repulsive force between the N poles. The second magnet 2302 may be configured such that the N pole of the pair of permanent magnets faces the outside as opposed to the fourth magnet 2304.

Except for the second magnet 2302 and the fourth magnet 2304, the first magnet 2301, the third magnet 2303, the fifth magnet 2305 to the eleventh magnet 2311 have different poles on one side and the other side. Have.

In summary, in the second and third states, one side of the first magnet (2301s, S pole), the other side of the third magnet (2303n, N pole), and one side of the second magnet (2302n, N pole) and the fourth magnet The other surfaces 2304s (S pole) of are coupled to fix the first area 271 of the case 270 from being separated from the rear surface of the second display unit 251.

In the second state, one side of the third magnet (2303s, S pole), one side of the ninth magnet (2309n, N pole), one side of the sixth magnet (2306s, S pole) and one side of the seventh magnet (2307s, S pole) ) And one surface (2304s, S pole) of the fourth magnet and one surface (2305n, N pole) of the fifth magnet are combined to form a third area 273 of the case 270 on the front surface of the second display unit 251 Can be fixed.

In the third state, the other side of the fifth magnet (2305s, S pole) and the other side of the eighth magnet (2308n, N pole) are coupled, and the other side of the ninth magnet (2309s, S pole) and the other side of the 11th magnet (2311n, N pole) can be combined.

In the fourth state, one side (2302n, N-pole) or the other side (2302n, N-pole) of the second magnet is combined with the other side (2305s, S-pole) of the fifth magnet, and the second display unit 251 is fixed in an erect state. can do. In the fifth state, the second magnet 2302 is coupled to the other surface 2309s (S-pole) of the ninth magnet, so that the second display unit 251 can mount a larger angle with the mounting surface.

In addition, the mobile terminal 100 combines with one surface of the eleventh magnet 2311 located in the second area 272 of the case 270 of the display device 200 to connect the mobile terminal 100 to the second area 272 as shown in FIG. It can be fixed to the area 272.

The power terminal 249 is electrically connected to the wiring unit 242 to supply power to the second display unit 250. According to this structure, power supplied to the second display unit 250 may be transmitted from the mobile terminal through a wired path.

According to the structure described above, the display system performs an operation of interlocking the first and second display units 250 with each other using short-range wireless communication and a wired power supply path. Hereinafter, the structure and function of the mobile terminal will be described first, and then the control operation will be described.

11 is a diagram showing an operation sequence of the display system of the present invention. The display system refers to a system in which the above-described mobile terminal 100 and the display device 200 are connected to each other and operate.

The display device 200 is connected to the mobile terminal 100 (S305). The mobile terminal 100 detects whether the display device 200 is connected (s310). For example, the mobile terminal 100 may determine whether the display device 200 is connected to the mobile terminal 100 by sensing the magnetic force of a magnet positioned on the display device 200. In order to detect the connection of the display device 200, the mobile terminal 100 may include a sensing unit 240 for sensing magnetic force, such as a Hall sensor.

When the connection of the display device 200 is detected, the mobile terminal 100 supplies power to the display device 200 (S315). The display device 200 may be driven by receiving power from the mobile terminal 100 without having a separate battery for portability. If necessary, power may be supplied by connecting a cable to the second interface unit 262 in the form of a terminal.

When power is supplied to the display device 200, power is supplied to each component of the display device 200, thereby turning on the power (S320 ). When each component of the display device 200 is booted and becomes an operable state, information indicating an operable state may be transmitted to the mobile terminal 100. In this case, it may be transmitted to the mobile terminal 100 through the first interface unit 261. The first interface unit 261 may transmit a signal by direct connection such as a pogo pin or a terminal type, or may transmit a signal through short-range wireless communication.

When the mobile terminal 100 detects that the display device 200 is in the Power on state (S325), the mobile terminal 100 and the display device 200 transmit and receive an image signal communication control signal with each other (S330). The mobile terminal 100 transmits a digital image signal (s335). The display apparatus 200 receives a digital image signal (S340).

In this case, different home screen pages may be displayed on the first and

second display units

151 and 251, respectively, or the same home screen page may be displayed over the first and

second display units

151 and 250. In addition, various information may be output on the first and

second display units

151 and 250 according to circumstances.

In the connected situation, the second display unit 251 is not immediately activated, but only the first display unit is activated, and if a specific command is input to the mobile terminal, the second display unit may be switched to the activated state. Alternatively, when only the touch sensor on the second display unit 251 is activated and a touch applied to the second display unit 251 corresponds to a preset type of touch, it may be driven in an activated state. The second display unit 251 may be activated directly from the control unit 280 of the display device, but after transmitting the touch signal to the control unit 180 of the mobile terminal 100, the second display unit ( 251) may be generated.

Conversely, when connected, the first display unit 151 may remain inactive and only the second display unit 251 may be activated. The touch sensor located on the EWU first display unit 151 is

The display apparatus 200 converts the received digital image signal into a signal suitable for display (S345). This step may be performed by the controller 280 of the display apparatus 200, but may also be performed by the controller 280 of the mobile terminal 100. In the former case, the image signal received from the mobile terminal 100 may be enlarged or adjusted to fit the size of the second display unit 251 of the display device 200.

In the latter case, the mobile terminal 100 receives information such as the size, resolution, and mounting direction of the second display unit 251 of the display apparatus 200, and based on this, the second display unit 251 of the display apparatus 200 It can be converted to a screen suitable for the size of) and transmitted. The display apparatus 200 may display the converted digital image signal (S350).

When the display device 200 is provided with the input unit 220, the input received from the input unit 220 can be transmitted to the mobile terminal 100.

The operating current (or power) is supplied to the power supply unit 291 of the second display unit 250 through an electrical connection path of the second circuit board provided in 220.

Meanwhile, as described above, the mobile terminal 100 may be detachably coupled to the first body 210. In addition, the mobile terminal may be formed to detect whether it is coupled to the first body 210. For the detection, the first body 210 includes a magnet 245 on one surface facing the mobile terminal 100, and at the rear side of the mobile terminal, the body of the mobile terminal is 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 hall sensor senses the magnetic field, the mobile terminal recognizes that it is coupled with the display device, and may perform a preset control.

For example, when a magnetic field is sensed by the hall sensor 143, the controller 180 of the mobile terminal 100 supplies an operating current to the second display unit 250 provided in the second body 220 The power supply unit 190 may be controlled so as to be performed.

That is, the second display unit 250 provided in the second body 220 may be configured to operate based on power supplied from the mobile terminal 100.

In this way, when the operating current is supplied to the second display unit 250, the system of the second display unit 250 is booted and initialized, and thus the system may be in an operable standby state.

At this time, the second display unit 250 has any one of an activated state and a deactivated state, and even when the second display unit 250 is deactivated, the touch sensor provided in the second display unit 250 ( Alternatively, the touch panel 252 may be driven in an activated state to sense a touch applied to the second display unit 250.

Meanwhile, when the second display unit 250 is activated, the mobile terminal 100 provides screen information to be output on the display 251 provided in the second display unit 250 through the first wireless communication unit 116 (Or a digital video signal) is transmitted to the second wireless communication unit 283 side. In this case, the digital image signal may be transmitted as a signal in a frequency band of 60 GHz wirelessly through a wireless connector, as described above.

In the second display unit 250, as described above, data (eg, digital image signals, etc.) from the first wireless communication unit 116 through the second wireless communication unit 283 and the second circuit board 244 ) Can be received. In this case, the digital image signal may be converted into data in a form that can be output from the second display unit 250 through the data conversion unit 282. For example, the second display unit 250 may be composed of an LCD panel, and at this time, the digital image signal in DP format received from the mobile terminal 100 is transmitted through the data conversion unit 282 to the LCD panel. It is converted into a data format that can be received (MIPI format), and may be transmitted and output to the display 251.

Meanwhile, the type of data transmitted and received through the first and second

wireless communication units

116 and 283 may be preset. For example, through the first and second

wireless communication units

116 and 283, only data corresponding to an image signal may be transmitted and received.

At this time, signals that need to be transmitted between the mobile terminal 100 and the display unit 250, such as communication control signals, touch signals, and brightness control signals excluding image signals, are transmitted through the first and second signal processing units 181 through multiple input channels. , 281), the first circuit board 243 and the power terminal (for example, pogo-pin, 249), it is possible to transmit and receive. Meanwhile, the initialization of the second display unit 250 may be controlled by a control unit included in the second display unit 250.

As described above, the mobile terminal according to the present invention may control information output to the display unit 250 provided in the display apparatus 200. That is, the driving of the second display unit 250 may be controlled by the mobile terminal 100.

At this time, the controller 180 may allocate at least one stack for controlling the second display unit 250 on the memory 170 in order to control the second display unit 250, The allocation of such a stack may vary according to the activation or deactivation state of the second display unit 250.

A stack may be one of a structure in which data is stacked. The structure of stacking data may be in a stack format and a queue format. The stack may be a first-in, first-out data structure, and the queue may be a first-in, first-out data structure.

The controller 180 of the mobile terminal according to the present invention may stack tasks on different stacks according to the type of task to be executed.

In the present invention, the stack can be classified according to the type of work to be performed. For example, i) a stack in which tasks for performing tasks related to a home screen page are stacked, and ii) performing tasks related to an application The tasks in which the tasks for the task are stacked may be different.

Meanwhile, the application may be composed of a plurality of tasks, and the task may be a unit function in which a specific application is executed.

For example, a navigation application and an image viewer application are divided into different tasks, and various operations within the navigation application may exist in an activity unit within the task of the navigation application.

Hereinafter, a method of allocating a stack for driving the second display unit 250 in a mobile terminal according to the present invention will be described in more detail with reference to the accompanying drawings. 13 is a flowchart illustrating a control method between a mobile terminal and a display unit included in the display apparatus 200 in the display system according to the present invention. 14A and 14B are conceptual diagrams illustrating a memory control method according to the present invention, and FIG. 15 is a conceptual diagram illustrating a scene in which a home screen page is output in a display system according to the present invention.

First, as shown in FIG. 14A, at least one stack may be allocated to the memory 170 of the mobile terminal 100. Stacks on the memory 170 may be classified and allocated according to a category (or type) of a task. As shown in FIG. 15A, a first main stack (or main stack) that manages tasks for a home screen page Home stack, 610), a second main stack (or main app stack, 620) that manages the execution of applications, and a third main stack (or main stack) that manages the history of recently executed applications. It can be broadly classified into a cent app stack (630).

When there is no application running in the foreground or background in the mobile terminal 100, the second main stack 620 and the third main stack 630 may not be allocated, and only the first main stack 610 is allocated. Can be.

In addition, differently, if there is no application running in the foreground or background in the mobile terminal 100, the second main stack 620 and the third main stack 630 are allocated, but the tasks included in each stack are It may not exist.

Meanwhile, in a state in which the second display unit 250 is deactivated, a stack for the second display unit 250 may not be allocated on the memory 170 of the mobile terminal 100 as shown in FIG. 14A. have. That is, when the second display unit 250 is deactivated, only at least one of the first main stack 610, the second main stack 620, and the third main stack 630 may be allocated and present.

That is, when the second display unit 250 is deactivated, a memory for the second display unit 250 is not allocated on the memory 170.

However, when the first display unit 151 is in an active state and the second display unit 250 is in an inactive state, the second display unit 250 is in an active state based on an external input to the display system 300 or the like. When converted to (S501), the control unit 180 of the mobile terminal 100 may additionally allocate a stack for managing the screen and functions displayed on the second display unit 250.

For example, when a preset type of touch input for activating the second display unit 250 in an inactive state is applied to the second display unit 250, the second display unit 250 is in an activated state. Is converted.

The controller 180 of the mobile terminal detects the activation state of the second display unit 250 (S502), and based on the detection of the activation state of the second display unit 250, as shown in FIG. 14B, At least one stack for the second display unit 250 may be generated on the memory.

The detection of the activation state of the second display unit 250 by the controller 180 of the mobile terminal may be performed based on the reception of the preset type of touch input.

That is, when a touch is applied from the second display unit 250, the second display unit 250 may transmit a touch signal corresponding to the touch to the mobile terminal 100. When a touch is sensed while the second display unit 250 is deactivated, a touch signal corresponding to the sensed touch is transmitted to the mobile terminal 100 through the second wireless communication unit 283 described above. I can.

And, when the touch according to the received touch signal corresponds to a preset type of touch, the mobile terminal 100 transmits a control command for activating the second display unit 250 through the first wireless communication unit 116, It can be transmitted to the second display 250 side.

The control unit 180 of the mobile terminal includes at least one stack for controlling information output through the second display unit 250 on the memory 170 based on the activation of the second display unit 250 A (stack) can be created (S503).

More specifically, the control unit 180 of the mobile terminal manages a task for the home screen page displayed on the second display unit 250 on the memory based on the activation of the second display unit 250 I) the first sub-stack (or sub-home stack, 640), ii) the second sub-stack (or sub-app stack, 935) that manages the execution of the application, and iii) the recently executed At least one of a third sub-stack (or a sub-recent app stack, 936 (refer to FIG. 9B)) that manages the application history may be allocated.

In this case, when there is no application being output or output on the second display unit 250, only the first sub-stack 640 may be allocated as shown in FIG. 14B.

The first sub-stack 640 relates to a stack related to a job of a home screen page output to the second display unit 250, and in the present invention, the mobile terminal 100 and the second display unit 250 Different home screen pages may be displayed.

As illustrated in FIG. 15, the home screen page 710 output to the second display unit 250 may be a home screen page that is separately allocated for the second display unit 250.

Alternatively, the home screen page output to the second display unit 250 may be any one of a plurality of home screen pages that can be output from the mobile terminal 100. At this time, the controller 180 of the mobile terminal is configured to display the same home screen page in the first display unit 151 and the second display unit so that the same home screen page is not displayed on the first display unit 151 and the second display unit 250. Stacks related to the home screen page included in the first main stack 610 and the first sub-stack 640 may be controlled so that the home screen page is not output.

Meanwhile, the second sub-stack and the third sub-stack may be additionally allocated when an application is executed on the second display unit 250 (or an execution screen of the application is displayed).

As described above, when the second display unit 250 is activated and a stack for the second display unit is allocated on the memory, the controller 180 of the mobile terminal displays the information included in the stack and the second display unit Transfer to (250) (S503). The information included in the stack may be transmitted to the second display unit 250 through the first and second

wireless communication units

116 and 283.

wireless communication units

116 and 283 may be preset. For example, through the first and second

wireless communication units

116 and 283, only data corresponding to an image signal is transmitted and received, and the touch signal is transmitted through the first and

second circuit boards

243 and 244. It is also possible to communicate to the (100) side. That is, signals that need to be transmitted between the mobile terminal 100 and the second display unit 250, such as communication control signals, touch signals, and brightness control signals excluding video signals, are transmitted through the first and second signal processing units through multiple input channels. Through (181, 281, see FIG. 4), it is possible to transmit and receive through the first circuit board 243 and the power terminal (eg, pogo-pin, 249).

The data connection path at this time is the power supply unit 191 of the mobile terminal 100, the power terminal (eg, pogo-pin, 249) of the first body 210, the first circuit board 243 and the connection unit 230 ) May be formed organically between the wiring part 242 provided in the ), the second circuit board provided in the second body 220, and the second display part 250.

In this way, when the second display unit 250 is driven in an active state and a stack for the second display unit 250 is allocated on the memory 170 of the mobile terminal, the second display unit 250 When is converted back to the inactive state (S505), the controller 180 of the mobile terminal may delete the sub-stack generated for the second display unit 250 from the memory (S507).

That is, when the controller 180 of the mobile terminal detects an inactive state of the second display unit (S506), the controller 180 may delete all substacks related to the second display unit from the memory.

That is, in the present invention, only in a state in which the second display unit is activated, a stack for controlling the second display unit is generated, and the second display unit is driven independently of the operation of the mobile terminal. In addition, when the second display unit is deactivated, all stacks associated with the second display unit 250 are deleted from the memory, thereby reducing a space occupied by the memory for the second display unit unnecessarily on the memory 170.

On the other hand, the controller 180 of the mobile terminal detects that the second display unit is switched to the deactivated state, based on the switching of the electronic device 300 to the closed state or a touch input applied to the electronic device 300. Can be done.

Hereinafter, in consideration of a situation in which the second display unit is activated, a method of generating a stack related to the second display unit will be described in more detail with reference to the accompanying drawings. 16 is a flowchart illustrating a control method between a mobile terminal and a display unit included in the display apparatus 200 in the display system according to the present invention.

Screen information output on the first display unit 151 may be various, and may be variously changed according to settings such as a home screen page, an execution screen of an application, a web page, a setting screen, or a user's selection.

When a touch is applied from the second display unit 250, the second display unit 250 may transmit a touch signal corresponding to the touch to the mobile terminal 100. When a touch is detected while the second display unit 250 is deactivated (S804), a touch signal corresponding to the sensed touch is transmitted to the mobile terminal 100 through the second wireless communication unit 283 Can be.

And, when the touch according to the received touch signal corresponds to a preset type of touch, the mobile terminal 100 provides a control command for activating the second display unit 250 and output to the second display unit 250. Screen information (image signal) may be transmitted to the second display 250 through the first wireless communication unit 116.

When a touch is applied to the second display unit 250, a touch signal corresponding to the touch may be transmitted to the first wireless communication unit 116 through the second wireless communication unit 283. Then, the controller 180 of the mobile terminal determines whether the touch signal received through the first wireless communication unit corresponds to the preset type of touch (S806), and as a result of the determination, the touch signal is the preset type In the case of a touch of, a control signal and screen information for activating the second display unit 250 may be transmitted to the second wireless communication unit through the first wireless communication unit.
