The rear input unit may be disposed to overlap the front display unit 151 in the thickness direction of the terminal body. As an example, when the user holds the terminal body with one hand, the rear input unit may be disposed on the rear upper end of the terminal body so that the user can easily manipulate the terminal body using the index finger. However, the present invention is not necessarily limited thereto, and the position of the rear input unit may be changed.

When the rear input unit is provided on the rear surface of the terminal body, a new type of user interface can be implemented using the rear input unit. In addition, when the touch screen or the rear input unit described above replaces at least some functions of the first operation unit 123a provided on the front of the terminal body, and the first operation unit 123a is not disposed on the front of the terminal body, The display unit 151 may be configured with a larger screen.

Meanwhile, the mobile terminal 100 may be provided with a fingerprint recognition sensor for recognizing a user's fingerprint, and the controller 180 may use fingerprint information detected through the fingerprint recognition sensor as an authentication means. The fingerprint recognition sensor may be embedded in the display unit 151 or the user input unit 123.

The microphone 122 is configured to receive a user's voice and other sounds. The microphone 122 may be provided in a plurality of locations and configured to receive stereo sound.

The interface unit 160 becomes a passage through which the mobile terminal 100 can be connected to an external device. For example, the interface unit 160 is a connection terminal for connection with other devices (eg, earphones, external speakers), a port for short-range communication (eg, an infrared port (IrDA Port), a Bluetooth port (Bluetooth Port), a wireless LAN port, etc.], or at least one of a power supply terminal for supplying power to the mobile terminal 100. The interface unit 160 may be implemented in the form of a socket for accommodating an external card such as a subscriber identification module (SIM) or a user identity module (UIM), or a memory card for storing information.

A second camera 121b may be disposed on the rear surface of the terminal body. In this case, the second camera 121b has a photographing direction substantially opposite to that of the first camera 121a.

The second camera 121b may include a plurality of lenses arranged along at least one line. The plurality of lenses may be arranged in a matrix format. Such a camera may be referred to as an'array camera'. When the second camera 121b is configured as an array camera, an image may be photographed in various ways using a plurality of lenses, and an image of better quality may be obtained.

The flash 124 may be disposed adjacent to the second camera 121b. The flash 124 illuminates light toward the subject when photographing the subject with the second camera 121b.

A second sound output unit 152b may be additionally disposed on the terminal body. The second sound output unit 152b may implement a stereo function together with the first sound output unit 152a, and may be used to implement a speakerphone mode during a call.

At least one antenna for wireless communication may be provided in the terminal body. The antenna may be embedded in the terminal body or may be formed in a case. For example, an antenna that forms a part of the broadcast reception module 111 (refer to FIG. 5) may be configured to be retractable from the terminal body. Alternatively, the antenna may be formed in a film type and attached to the inner surface of the rear cover 103, or a case including a conductive material may be configured to function as an antenna.

The terminal body is provided with a power supply unit 190 (refer to FIG. 5) for supplying power to the mobile terminal 100. The power supply unit 190 may include a battery 191 built in the terminal body or configured to be detachable from the outside of the terminal body.

It is illustrated. When the battery 191 is configured to be detachably attached to the terminal body, the rear cover 103 may be detachably coupled to the rear case 102.

7 is a block diagram illustrating a terminal set 10 related to the present invention. For better understanding, reference is made to FIGS. 1 to 6 together.

As described above, the terminal set 10 of the present invention is divided into a mobile terminal 100 and an auxiliary device 200, and the auxiliary device 200 is further divided into a terminal case 210 and an extended display module 260. The extended display module 260 again includes a display case 280 and a rear member 290. A first display 151 is provided in the mobile terminal 100 and a second display 261 is provided in the extended display module 260.

The first display 151 and the second display 261 may be output in connection with each other. For example, the first display 151 and the second display 261 may be mirrored and output, or a screen output on the first display 151 may be moved to the second display 261 and output, or An execution screen of one application or a plurality of linked applications may be divided and output on the two

displays

151 and 261. For example, the controller of the game application may output the game content to the first display 151 and the second display 261. That is, the terminal set 10 of the present invention can operate like a single device having a plurality of displays, which means that the auxiliary device 200 shares several configurations of the mobile terminal 100.

The controller 180 and the power supply unit 190 of the mobile terminal 100 may supply power to the second display 261 as well as the first display 151 and transmit and receive data. Accordingly, the auxiliary device 200 can operate without a separate control unit and a power supply unit. This can reduce the weight or volume of the auxiliary device 200 and achieve the effect of reducing manufacturing cost.

More specifically, the controller 180 is provided in the mobile terminal 100 and controls the operations of the first display 151 and the second display 261. That is, the controller 180 controls the overall operation of the mobile terminal 100 as described with reference to FIG. 5 and, in addition, controls the operation related to the output of the second display 261. The controller 180 may include an application processor (AP) or a physical form of a System-On-Chip (SOC).

The memory 170 provided in the mobile terminal 100 may be used for the operation of the first display 151 and furthermore the second display 261. For example, a game application stored in the memory 170 of the mobile terminal 100 is driven by signal processing and calculation of the controller 180, and data for screen output is output to the first display 151 or an auxiliary device. It may be transmitted to 200 and output to the second display 261.

The power supply unit 190 of the mobile terminal 100 may supply power for the operation of the auxiliary device 200 as well as the operation of the internal configuration of the mobile terminal 100. The auxiliary device 200 may include a switch 211 for selectively supplying power. In particular, the switch 211 may be provided on the terminal case 210 side.

That is, the second display 261 of the auxiliary device 200 may be driven depending on the application processor, the memory 170 and the power supply unit 190 of the mobile terminal 100. However, if necessary, a volatile memory for temporarily storing data, a small power supply unit, etc. may be provided, so that it may be used auxiliary for operation control. In particular, the extended display module 260 may be provided with a second display controller 262 for controlling the output of the second display 261. The second display control unit 262 may convert data received from the mobile terminal 100 and output it to the second display 261 or perform other auxiliary tasks necessary for outputting the second display 261. Furthermore, the auxiliary device 200 may include a touch panel corresponding to the second display 261 to generate, process, and transmit an input signal through the touch panel.

In addition, the auxiliary device 200 and the mobile terminal 100 are provided with a magnet and a hall sensor for sensing mutual coupling, and a user interface for starting interworking with the second display 261 May be output to the first display 151 or power supply to the second display 261 may be started.

In order to implement the above operation, the auxiliary device 200 and the mobile terminal 100 are electrically connected. More specifically, the second display 261 of the extended display module 260 is electrically connected to the mobile terminal 100 to receive power and transmit and receive data. The terminal case 210 serves to electrically connect both components between the extended display module 260 and the mobile terminal 100.

For the electrical connection of both configurations, the mobile terminal 100 is physically coupled to the auxiliary device 200, and the auxiliary device 200 provides a circuit for electrically connecting the mobile terminal 100 and the second display 261. Equipped.

The extended display module 260 and the terminal case 210 may be provided integrally, or may be provided to selectively combine or separate. Here, the meaning of all non-separable does not mean that it is manufactured as a single member, but that it is manufactured in a form that the user does not frequently combine or separate.

Advantages of omitting a structure that selectively enables electrical and physical coupling between the extended display module 260 and the terminal case 210 when the extended display module 260 and the terminal case 210 are provided in a non-separable form There is this.

In this case, the fixed area 291 of the rear member 290 of the extended display module 260 may be fixed to the rear surface of the terminal case 210. The fixing can be implemented by an adhesive.

On the other hand, when the detachable auxiliary device 200, that is, the extended display module 260 and the terminal case 210 are implemented to be separated and combined, there are advantages as follows.

First, when the extended display module 260 is not used, the function of physically protecting the mobile terminal 100 can be obtained by combining only the terminal case 210 with the mobile terminal 100. In the conventional case where the extended display module 260 is always fixed to the terminal case 210, it must be used in a state of large volume and weight even though the extended display module 260 is not used, and the grip of the mobile terminal 100 Also degrades. Therefore, by combining only the terminal case 210 to the mobile terminal 100, this disadvantage can be compensated.

Second, the detachable extended display module 260 may be continuously used even if the mobile terminal 100 and the terminal case 210 are replaced. For example, even if the terminal case 210 used in conjunction with a specific mobile terminal 100 is damaged or lost, only the terminal case 210 may be replaced to use the existing extended display module 260 as it is.

Third, even when a mobile terminal 100 and a terminal case 210 having a different shape or size from the existing mobile terminal 100 are used, the expanded display module 260 used in the past may be combined and used. . Of course, this assumes that the mobile terminal 100 and the terminal case 210 having different shapes or sizes are configured to be compatible with the existing extended display module 260.

Fourth, the extended display module 260 may be combined in a different form. For example, when the extended display module 260 is turned over and configured to be coupled to the terminal case 210, the two

displays

151 and 261 can be viewed in the same direction or in opposite directions, thereby allowing various user experiences ( user experience).

When the extended display module 260 and the terminal case 210 are separated, the circuit of the auxiliary device 200 is also separated. Among the circuits of the auxiliary device 200, a circuit configuration provided in the extended display module 260 is defined as a module circuit unit 270, and a circuit configuration provided in the terminal case 210 is defined as a case circuit unit 220.

The extended display module 260 and the terminal case 210 may each have

coupling terminals

271 and 221 to connect the module circuit unit 270 and the case circuit unit 220. For classification, the former is defined as a module-side coupling terminal 271 and the latter as a case-side coupling terminal 221. The charging port 161 of the mobile terminal 100 may be connected to the terminal coupling terminal 223 of the terminal case 210. Meanwhile, the terminal case 210 additionally has a cable coupling terminal 222 to separately provide a point where an external cable can be connected.

In the case of a separate type, the extended display module 260 and the terminal case 210 may be provided with wireless communication units 226 and 272 that transmit and receive data to and from each other. This is because an excessive number of pins is required to perform both data and power transmission to the

coupling terminals

221 and 271. At this time, it is preferable that the two wireless communication chips 226 and 272 are provided in corresponding areas when combined.

7 is based on the premise that the extended display module 260 and the terminal case 210 are separated, but when provided as an integral type as described above, the two

coupling terminals

221 and 271 and the wireless communication units 226 and 272 are Can be omitted.

The rear member 290 may include two

rigid brackets

2911 and 2921 spaced apart and a sheet 294 of a flexible material connecting the two

brackets

2911 and 2921 in order to have a folding area 293. . In particular, the sheet 294 may be adhered by covering one surface of the two

brackets

2911 and 2921. The two

brackets

2911 and 2921 separated from each other become a fixed area 291 and a non-fixed area 292, respectively, and an area between the two

brackets

2911 and 2921 becomes a folding area 293.

The fixed area 291 and the non-fixed area 292 may have a mutually symmetric shape with a boundary of the folding area 293. When the above-described one side edge is the left or right side of the rear member 290 (or the terminal case 210, see Fig. 3), the folding area 293 is the rear member 290 (or the terminal case 210, see Fig. 3). )) to form a vertical line. In addition, the left and right center lines of the rear member 290 and the left and right center lines of the terminal case 210 (refer to FIG. 3) are arranged to match, and as described above, the fixed area 291 and the non-fixed area 292 are mutually symmetrical. In the case of having a shape, even when the display case 280 is in the state of FIG. 3(a) and the state of FIG. 3(b), it is possible to implement a uniform arrangement of the

displays

151 and 261 without any distortion.

The fixed area 291 and the non-fixed area 292 may include magnets 2912 and 2922 that generate mutual attraction at points corresponding to each other. This guides the user to the rotation when creating the state of FIG. 3(b), and provides a certain amount of force to maintain the state of FIG. 3(b).

Meanwhile, the terminal case 210 (refer to FIG. 3) may include a magnet (not shown) that generates an attractive force in response to the magnet 2922 of the non-fixed area 292. This guides the user to rotate when creating the state of FIG. 3 (a), and provides a certain amount of force that can maintain the state of FIG. 3 (a).

In addition, the display case 280 may also include a magnet (not shown) that generates an attractive force in response to the magnets 2912 and 2922 of the rear member 290. This guides the user to the rotation when creating the state of FIG. 3(c), and provides a certain amount of force to maintain the state of FIG. 3(c).

The hinge part 310 provides a rotation axis through which the display case 280 rotates by fastening the display case 280 with one edge of the rear member 290. Since the display case 280 and the rear member 290 have a predetermined thickness, the hinge unit 310 has two parallel rotation axes, so that the display case 280 can rotate until it contacts the rear surface of the rear member 290. It is desirable to secure the rotation space so that it is possible.

The two parallel rotation axes may be implemented by a case 312 surrounding the two two shafts 311. In particular, the two shafts 311 and the case 312 are formed of a metal material to ensure durability and generate sufficient friction for realizing a free stop hinge.

As an additional method for generating sufficient frictional force between the shaft 311 and the case 312, the case 312 is composed of a seating portion 3121 and a friction cover 3122 and may be screwed.

One (3111) of the two

shafts

3111 and 3112 protruding from the formed hinge part 310 to the outside of the case 312 is fastened to the rear member 290, and the other 3112 is fastened to the display case 280 Can be. Fastening of the two

shafts

3111 and 3112 may be screwed by being covered with the fixing cover 313.

As described above, in order to minimize an increase in the volume and manufacturing cost of the terminal set 10, the auxiliary device 200 is a terminal coupling terminal 223 that is coupled with a charging port 161 that is essentially provided in the mobile terminal 100. ) Can have the form. Since the charging port 161 provided as an essential component of the mobile terminal 100 has a power pin and a data pin, both power supply and data transmission and reception are possible only by connecting the charging port 161 and the terminal coupling terminal 223. .

A typical form of the charging port 161 may be a USB-C type terminal, but is not limited thereto, and any type of a power pin and a data pin may be used.

The terminal coupling terminal 223 may have a shape and a pin corresponding to the charging port 161. Therefore, when the charging port 161 is a USB-C type terminal, the terminal coupling terminal 223 is also provided in the form of a USB-C type terminal.

The cable coupling terminal 222 is provided in the auxiliary device 200 so that the terminal coupling terminal 223 can be connected from the external cable 501 even when the terminal coupling terminal 223 is coupled to the mobile terminal 100. The cable coupling terminal 222 is electrically connected to the terminal coupling terminal 223 and the charging port 161 to supply power to the terminal set 10 from the outside or perform data transmission/reception with the outside. The cable coupling terminal 222 may include a data pin and a power pin in the same manner as the terminal coupling terminal 223.

The cable coupling terminal 222 may be provided in a form in which the terminal 502 of the cable 501 is inserted and fixed, but the magnet 503 in which the connection state of the two

terminals

222 and 502 is maintained by magnetic force. It may be provided in a combination manner. The magnet 503 coupling method has the advantage that the possibility of damage to the terminal can be reduced, and the cable and the cable coupling terminal can be easily connected or separated.

The cable coupling terminal 222 may be formed of a terminal coupling terminal 223 and one metal member 224. The metal member 224 may be directly mounted on the terminal case 210, but may be coupled to the bracket mounting portion 2104 of the terminal case 210 through an additional bracket 225. Since the additional bracket 225 has a relatively large surface area, reliability of coupling with the terminal case 210 may be guaranteed.

When the direction in which the auxiliary device 200 of the mobile terminal 100 is seated and the direction in which the terminal coupling terminal 223 is inserted are vertical, the mobile terminal 100 is mounted on the terminal case 210 and the terminal coupling terminal 223 It can be difficult to combine. To solve this, the auxiliary device 200 of the present invention may provide a rotation axis to the terminal case 210 so that the terminal coupling terminal 223 can be tilted outside the seating area 2101. That is, an area of the terminal case 210 may include a terminal rotating member 2105 capable of rotating with respect to the seating area 2101 while mounting the terminal coupling terminal 223.

When the mobile terminal 100 is fastened to the terminal coupling terminal 223 and coupled to the seating area 2101, the terminal rotating member 2105 has the same shape as the outer boundary of the terminal case 210 so that there is no foreign body feeling. Can be implemented.

It is obvious to a person skilled in the art that the present invention can be embodied in other specific forms within the scope not departing from the spirit and essential features of the present invention.

The above detailed description should not be construed as restrictive in all respects and should be considered as illustrative. The scope of the present invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.

The above-described features may be partially or entirely applied to the field of mobile terminals and auxiliary devices to which the present invention belongs.
