The wireless communication between the stylus pen 300 and the mobile terminal 100 may be performed through a short distance communication and the short distance communication technology may be Bluetooth, Radio Frequency Identification (RFID) , Infrared data association (IrDA), ultra wideband (UWB), ZigBee, and Near Field Communication (NFC). Among these, the NFC has an advantage that it can perform wireless communication with the mobile terminal 100 without performing a pairing process.

The memory 330 is for storing various data necessary for the operation of the stylus pen 300, and the memory 330 may include a control area and a data area. The control area is an area for storing a program for operation of the stylus pen 300, and the data area may be an area for storing data received from the outside.

The user input unit 350 generates input data for controlling the operation of the stylus pen 300. The user input unit 350 may include a button or a touch sensor (static / static) exposed to the outside of the stylus pen 300.

The display unit 370 displays the operation state of the stylus pen 300. [ The operation state of the stylus pen 300 may indicate whether the data area is empty or whether data is being transmitted or received through the wireless communication unit. The display unit 370 for displaying the operation state of the stylus pen 300 may include at least one of a light emitting module such as an LED (Light Emitting Module) and a display module. When the display unit 370 includes a light emitting module, the controller 340 can express various operating states of the stylus pen 300 based on whether the light emitting module emits light, luminosity, color, light emitting area, and the like. When the display unit 370 includes a display module, the control unit 340 may output the operation state of the stylus pen 300 to the display module.

The control unit 340 controls the overall operation of the stylus pen 300. The control unit 340 performs control and processing for wireless communication with the mobile terminal 100 and can determine an operation mode of the stylus pen 300 based on an external input input through the user input unit 350. [

For example, the control unit 340 may control the stylus pen 300 to be set to either the normal mode or the data transmission / reception mode based on whether the user input unit is receiving an external input. When the stylus pen 300 is touched to the touch screen while the stylus pen 300 is set to the normal mode, the mobile terminal 100 performs a touch operation of the stylus pen 300, ) Can be displayed. For example, when the stylus pen 300 touches the application execution icon, the application selected by the stylus pen 300 through the mobile terminal 100 can be executed. As another example, when the stylus pen 300 set in the normal mode with the mobile terminal 100 set in the handwriting input mode is touched on the touch screen, the handwriting 100 is provided with the handwriting along the touch trajectory of the stylus pen 300 An input may be output. Herein, the handwriting input mode is one of the settings provided for drawing a handwriting on the touch screen. When the handwriting input mode is set to the handwriting input mode, the control unit 180 of the mobile terminal 100 generates a touch input locus So that the handwriting can be drawn. Setting of the mobile terminal 100 in the handwriting input mode has already been well known in the art, so a detailed description thereof will be omitted.

Alternatively, if the stylus pen 300 is touched to the touch screen while the stylus pen 300 is set to the data transmission / reception mode, the control unit 340 determines whether the data area of the memory 330 is empty And may receive data from the mobile terminal 100 or control the data stored in the data area to be transmitted to the mobile terminal 100. [ For example, if the data area is empty, the controller 340 controls the wireless communication unit to receive data from the mobile terminal 100, and if there is pre-stored data in the data area, The wireless communication unit 320 can be controlled.

The power supply unit 360 serves to supply power necessary for operation of the respective components of the stylus pen 300. The power supply unit 360 may include a rechargeable battery. When the stylus pen 300 is inserted into the receiving groove 104 of the mobile terminal 100 illustrated in FIG. 2, the battery may be charged with power supplied from the power supply unit 190 of the mobile terminal 100.

The control unit 340 of the stylus pen 300 according to an exemplary embodiment of the present invention sets the wireless communication unit 320 to an unavailable state when the stylus pen 300 is set to the normal mode, When the stylus pen 300 is set to the data transmission / reception mode, the wireless communication unit 320 can be set to an available state.

Further, in order to allow the wireless communication to be performed only when the stylus pen 300 touches the touch screen of the mobile terminal 100, the controller 340 detects the contact of the stylus pen 300 with the touch screen, And may start wireless communication with the mobile terminal 100 based on the sensing signal.

5 is a perspective view of a stylus pen according to an embodiment of the present invention. Referring to FIG. 5, the stylus pen 300 may include a head portion 410 and a body portion 420. The head portion 410 is a portion for contacting the touch screen of the mobile terminal 100 and the body portion 420 is a portion for the user to grasp the stylus pen 300. [ Electronic parts constituting the stylus pen 300 may be mounted on the body part 420 of the stylus pen 300.

In order to improve the touch accuracy of the stylus pen 300, the cross sectional area of the head portion 410 may gradually decrease toward the tip. That is, one end of the stylus pen 300 has a pointed shape, so that it is possible to provide the user with the experience of using the pen. In addition, the sensing unit 310 may be positioned at the end of the head unit 410 to sense whether the stylus pen 300 touches the touch screen.

The body part 420 may include a display part 370 and a user input part 350 for displaying an operation state of the stylus pen 300. For example, as in the example shown in FIG. 5, the user input portion 350 may be implemented as a button on the surface of the body portion 420. However, as in the example shown in Fig. 5, the user input unit does not necessarily have to be implemented as a button. As another example, the user input unit 350 may be implemented in the form of a touch sensor on the surface of the body 420.

The body portion 420 may further include a charging terminal 362 for charging the battery of the power supply unit 360. When the stylus pen 300 is inserted into the receiving groove 104 of the mobile terminal 100, the power supply unit 360 supplies power from the power supply unit 190 of the mobile terminal 100 through the charging terminal 362 Can receive. Optionally, the charging terminal 362 may engage the head portion 410 rather than the body portion 420 of the stylus pen 300.

For convenience of description, it is assumed that the mobile terminal 100 described in the present invention includes at least one of the components shown in Fig. 1 together with the stylus pen 300 shown in Fig. In detail, the mobile terminal 100 according to the present invention includes a memory 160 for storing data, a display unit 151 for displaying information and receiving a touch input, and a stylus pen 300 for performing wireless communication The wireless communication unit 110 controls the wireless communication unit 110 to transmit the first data to the stylus pen 300 when it is determined that the data area of the wireless communication unit 110 and the stylus pen 300 are empty, It is assumed that the control unit 180 controls the wireless communication unit 110 to receive the second data from the stylus pen 300 when it is determined that the second data stored in the data area of the pen 300 exists in advance do. In some embodiments, it may be assumed that the mobile terminal 100 according to the present invention further includes a power supply 190 for supplying power to the out-of-configuration stylus pen 300.

In addition, since the mobile terminal 100 according to the present invention can be implemented more easily when the display unit 151 is a touch screen, it is assumed that the display unit 151 is a touch screen.

In the present invention, the stylus pen 300 'touches' the mobile terminal 100 may include not only when the stylus pen 300 and the mobile terminal 100 are touched, but also when they are touched .

In order to distinguish components of the mobile terminal 100 from the stylus pen 300, a 'first' notation is added to the components of the mobile terminal 100, Let's add the second word.

For convenience of explanation, data transmitted from the mobile terminal 100 to the stylus pen 300 is referred to as 'first data', data transmitted from the stylus pen 300 to the mobile terminal 100 is referred to as 'second data' .

Hereinafter, the operation of the mobile terminal 100 and the stylus pen 300 according to the present invention will be described in more detail with reference to the operation flow chart of FIG.

FIG. 6 illustrates a data sharing method using a stylus pen and a mobile terminal according to the present invention. First, when the stylus pen 300 touches the first touch screen (S601), the first controller 180 determines whether the stylus pen 300 is in the normal mode or the data transmission / reception mode (S602). Specifically, the first control unit 180 can determine whether the stylus pen 300 is set in the data transmission / reception mode through wireless communication with the stylus pen 300.

The second control unit 340 of the stylus pen 300 may set the stylus pen 300 to at least one of a normal mode and a data transmission / reception mode based on a user input to the second user input unit 350.

For example, the second controller 340 controls the stylus pen 300 in the normal mode or in the data transmission / reception mode based on whether the button exposed in the body portion 420 of the stylus pen 300 of FIG. 5 is pushed, . Specifically, when the button of the body part 420 is not pushed, the second control part 340 sets the stylus pen 300 to the normal mode (or data transmission / reception mode), and the button of the body part 420 The stylus pen 300 can be set to the data transmission / reception mode (or the normal mode).

As another example, the second control unit 340 may set the stylus pen 300 to the normal mode or the data transmission / reception mode depending on whether or not the stylus pen 300 is touched to the first touch screen. The second control unit 340 sets the stylus pen 300 to the normal mode (or the data transmission / reception mode) when the stylus pen 300 touches the first touch screen, The stylus pen 300 can be set to a data transmission / reception mode (or a normal mode) when the user touches the first touch screen. If it is determined that the stylus pen 300 is set in the normal mode, the first control unit 180 may control the operation of the mobile terminal 100 based on the touch input through the stylus pen 300 (S603 ). For example, when a predetermined object displayed on the first touch screen is touched through the stylus pen 300, the first controller 180 can perform an operation associated with the predetermined object touched by the stylus pen 300 have. For example, when the predetermined object selected by the stylus pen 300 is an execution icon of the application, the first control unit 180 can drive the application selected by the stylus pen 300. [

If the stylus pen 300 set in the normal mode touched the first touch screen while the mobile terminal 100 is set in the handwriting input mode, the first controller 180 controls the trajectory of the stylus pen 300 So that the handwriting input can be drawn.

For example, FIG. 7 illustrates how a handwriting input is drawn on the first touch screen by following the touch trajectory of the stylus pen. 7A, when the user draws the desired locus 710 on the first touch screen using the stylus pen 300 set to the normal mode, the control unit displays the desired locus 710 on the first touch screen, as in the example shown in FIG. It is possible to control the handwriting input 720 to be drawn on the touch screen along the desired trajectory.

If it is determined that the stylus pen 300 is set to the data transmission / reception mode other than the normal mode, the first controller 180 may determine whether the data area of the stylus pen 300 is empty (S604) . Specifically, the first controller 180 can determine whether the data area of the stylus pen 300 is in a blank state through wireless communication with the stylus pen 300.

If it is determined that the data area of the stylus pen 300 is empty, the first control unit 180 may transmit the first data to the stylus pen 300 (S605). On the other hand, if it is determined that the data area of the stylus pen 300 is not empty, the first control unit 180 may receive the second data stored in the data area of the stylus pen 300 (S606).

That is, the first controller 180 determines whether to transmit data to the stylus pen 300 or to receive data from the stylus pen 300 according to whether the data area of the stylus pen 300 is empty or not .

Here, the first data transmitted to the stylus pen 300 may include a handwriting input displayed on the first touch screen, a captured image of the image output through the first touch screen, a captured image capturing only a desired area of the first touch screen, An execution command of a predetermined application, and a file stored in the mobile terminal 100. [

The second data may be first data received from the mobile terminal 100 or another mobile terminal 100 according to the present invention.

The data transmission between the mobile terminal 100 and the stylus pen 300 will be described in detail with reference to the drawings described later.

8 is an exemplary view for explaining transmission of first data from the mobile terminal to the stylus pen.

When it is determined that the data area is blank at the time when the stylus pen 300 set in the data transmission / reception mode is contacted with the first touch screen, the first controller 180 transmits the first data to the stylus pen 300 The first wireless communication unit 110 can be controlled.

8A, when the handwriting input 810 is drawn on the first touch screen, the first control unit 180 causes the handwriting input 810 displayed on the first touch screen to be displayed on the stylus pen 300 As shown in Fig. The first control unit 180 can separate the handwriting input 810 and the background image so that only the handwriting input 810 can be transmitted to the stylus pen 300 as shown in FIG. May be transmitted to the stylus pen 300. The stylus pen 300 may also be used to transmit the image.

The first control unit 180 may give a graphic effect to the handwriting input 810 or the handwriting input 810 and the background image to be transmitted to indicate that data is being transmitted to the stylus pen 300. [ For example, the first control unit 180 applies an alpha blending effect to at least one of the handwriting input 810 and the background image to be transmitted, so that at least one of the handwriting input 810 and the background image is translucent So that the stylus pen 300 can notify that the first data is being transmitted.

The first control unit 180 may control the degree to which the graphic effect is applied according to the current transmission amount with respect to the total amount of transmission in giving the graphic effect to the handwriting input 810 and / or the background image to be transmitted. For example, assuming that the alpha blending effect is applied to the handwriting input 810 and / or the background image and the total capacity of the first data to be transmitted to the stylus pen 300 is 1 Mbytes, The handwriting input 810 and / or the transparency of the background image may be applied differently when the data size actually transmitted to the input device 300 is 100 Kbytes or 900 Kbytes. Accordingly, the user can easily grasp the transmission progress of the first data based on the change in the output of the handwriting input 810 and / or the background image displayed on the first touch screen.

The graphic effect that can be applied in the present invention can be implemented in various ways that the user can visually recognize, such as the size, the distortion, and the color change of the handwriting input 810 and / or background image to be transmitted. In this case, the first controller 180 may display the progress of the first data through the degree of change of the handwriting input 810 and / or the size, the degree of distortion, and the saturation of the background image.

According to another embodiment of the present invention, the first controller 180 may display a progress bar on the first touch screen or an indicator for indicating the progress of transmission of the text first data.

When the transfer of at least one of the handwriting input 810 and the background image to the stylus pen 300 is completed, the first control unit 180 transmits the first data to the first touch screen as in the example shown in FIG. 8A And a pop-up window 820 indicating completion is also output.

According to another embodiment of the present invention, the first controller 180 may control the captured image captured by the output image of the first touch screen to be transmitted to the stylus pen 300. Specifically, when it is determined that the data area of the stylus pen 300 set in the data transmission / reception mode is in a blank state, the first controller 180 generates a captured image of the image output through the first touch screen, And transmit the generated captured image to the stylus pen 300.

According to another embodiment of the present invention, the first control unit 180 may generate only the image output through the area defined by the user's handwriting input as a captured image, and then transmit the captured image to the stylus pen 300. That is, the first controller 180 does not generate the entire area of the first touch screen as a captured image, but may generate only the image output through the area defined by the handwriting input of the user as a captured image.

For example, when the handwriting input 830 of the closed curve is drawn on the first touch screen and the stylus pen 300 is touched to the inside of the area defined by the closed curve, as in the example shown in Fig. 8B, The stylus pen 300 may capture an image displayed inside the area defined by the closed curve and then transmit the captured image to the stylus pen 300. [

As another example, if the stylus pen 300 set to the data transmission / reception mode is stopped at a certain point after drawing the locus 840 of the closed curve on the first touch screen, as in the example shown in FIG. 8C, 180 may capture an image displayed inside the area defined by the closed curve 840 and then transmit the captured image to the stylus pen 300.

8B and 8C, the handwriting input 830 and the closed curve 840 drawn by the stylus pen 300 are circular, so that the first control unit 180 can be operated as in the example shown in FIGS. 8B and 8C You will be able to create a circular inside as a capture image.

8B and 8C, if the stylus pen 300 continues to touch the first touch screen even after the transmission of the captured image of the area defined by the handwriting input 830 and the closed curve 840 is completed, The controller 180 may extend the entire area of the first touch screen to the capture area. In this case, the first controller 180 sets the entire area of the image output through the first touch screen as a capture area, and then retransmits the captured image to the stylus pen 300. [

When the transmission of the captured image to the stylus pen 300 is completed, the first control unit 180 displays a pop-up window 820 indicating that the transmission of the captured image to the first touch screen is completed, as described with reference to FIG. .

According to another embodiment of the present invention, the first controller 180 may transmit the file stored in the mobile terminal 100 to the stylus pen 300. For example, as in the example shown in FIG. 8D, if any one is selected by the stylus pen 300 while the list of files stored in the mobile terminal 100 is displayed through the first touch screen, 180 can control the file selected by the stylus pen 300 to be transferred to the stylus pen 300. [ In the example of FIG. 8D, 'file 3' will be transmitted to the stylus pen 300.

At this time, if the file selected by the stylus pen 300 is a file to which a copyright protection technique is applied (for example, a file in which DRM (Digital Rights Management) is set), the second control unit 340 transmits the selected file to the stylus pen 300 A popup window 850 indicating that the file selected by the stylus pen 300 can not be transmitted without being transmitted may be displayed.

On the contrary, when the transmission of the file selected by the stylus pen 300 is completed, the first controller 180 displays a pop-up window 820 informing that transmission of the selected file to the first touch screen is completed, ) Can be controlled to be outputted.

According to another embodiment of the present invention, the first controller 180 may transmit an execution command of a predetermined application to the stylus pen 300. For example, as in the example shown in FIG. 8E, when the stylus pen 300 set in the data transmission / reception mode touches the execution icon of the predetermined application output through the first touch screen (in FIG. 8E, The first control unit 180 may transmit to the stylus pen 300 a command for executing a predetermined application (a command for executing an e-mail application is illustrated in the example of Fig. 8E).

When transmission of a command for executing an application with the stylus pen 300 is completed, the first controller 180, as described above with reference to FIG. 8A, displays a pop-up window indicating completion of transmission of an execution command to the first touch screen (200) is outputted.

In the above example, the touch input of the stylus pen 300 for receiving the first data from the mobile terminal 100 may include at least one of a contact touch and a proximity touch. That is, the first control unit 180 of the mobile terminal 100 determines whether the stylus pen 300 is touched to the mobile terminal 100 or the stylus pen 300 is touched to the mobile terminal 100 at least In one case, it is possible to control the first data to be transmitted to the stylus pen 300.

According to another example of the present invention, the mobile terminal 100 distinguishes between the case where the stylus pen 300 is touched to the first touch screen and the case where the stylus pen 300 is touched to the first touch screen, It is possible to control the first data to be transmitted to the stylus pen 300 only in the case of contact. The first control unit 180 of the mobile terminal 100 distinguishes between the case where the stylus pen 300 is touched and the case where the stylus pen 300 is touched in proximity to the stylus pen 300, The first data to be transmitted to the stylus pen 300 may be displayed on the first touch screen and the first data may be transmitted to the stylus pen 300 only when the stylus pen 300 is touched.

When the first data is a handwriting input as in the example described with reference to FIG. 8A or a file stored in the mobile terminal 100 as in the example described with reference to FIG. 8D, the first control unit 180 controls the stylus pen 300 The mobile terminal 100 may be controlled to delete the first data while transmitting the first data.

Specifically, when the stylus pen 300 requests the copying of the first data, the first controller 180 may control the first data to remain in the mobile terminal 100 while transmitting the first data. Otherwise, when the stylus pen 300 requests cutting of the first data, the first controller 180 may control to delete the first data to the mobile terminal 100 while transmitting the first data.

The second control unit 340 of the stylus pen 300 may request the mobile terminal 100 to copy and cut the first data based on the pressure sensed by the pressure sensor of the first sensing unit. For example, the second control unit 340 distinguishes between the case where the pressure sensed by the pressure sensor is in the first range and the case where the pressure is in the second range, and in the case of the first range, In the case of the range, it is possible to request the cut-off of the first data.

As another example, the second control unit 340 of the stylus pen 300 distinguishes between the case where the stylus pen 300 is touched with the mobile terminal 100 and the case where it is touched with the mobile terminal 100, It is possible. For example, when the stylus pen 300 is touched to the first touch screen, the second control unit 340 may copy the first data if the stylus pen 300 is touched to the first touch screen, 1 < / RTI > data.

In the above-described example, the mobile terminal 100 is illustrated as receiving a cut or copy request from the stylus pen 300, but the present invention is not limited thereto. According to another embodiment of the present invention, the mobile terminal 100 may determine whether to copy or cut the first data by itself without receiving a copy or cut request from the stylus pen 300. For example, if copying of the first data is set by the user, the first control unit 180 transmits the first data to the stylus pen 300, while the first data is also stored in the memory 160 of the mobile terminal 100 You will be able to control it to remain constant. On the other hand, if the cut-off of the first data is set by the user, the first control unit 180 transmits the first data to the stylus pen 300, May be deleted.

In order to control the user to select one of copying and cutting of the first data, the first control unit 180 may control the first touch screen to display a menu window for selecting copy, cut, etc. . Although not shown, the menu window may include a copy item for copying the first data and a cut item for cutting the first data.

At this time, the first control unit 180 distinguishes between the case where the stylus pen 300 is touched to the first touch screen and the case where the stylus pen 300 is touched to the first touch screen. When the stylus pen 300 is touched to the first touch screen, It can be controlled to be popped up. When the stylus pen 300 is touched after the menu window is popped up, the first control unit 180 can control the mobile terminal 100 according to the item selected by the stylus pen 300. Specifically, when the contact position of the stylus pen 300 is a copy item of the menu window, the first control unit 180 can perform the copy of the first data, and the contact position of the stylus pen 300 is cut In the case of the bet item, the first control unit 180 may perform cutting of the first data.

Next, the second data is transmitted from the stylus pen 300 to the mobile terminal 100 will be described in detail.

9 is an exemplary view for explaining that second data is transmitted from the stylus pen to the mobile terminal.

When the stylus pen 300 set in the data transmission / reception mode is contacted with the first touch screen, if it is determined that the data area is not in the blank state, the second control unit 340 transmits the data stored in the data area to the mobile terminal 100 The second wireless communication unit 320 can be controlled so that the second wireless communication unit 320 can transmit data.

When the first wireless communication unit 110 receives the second data from the stylus pen 300, the first control unit 180 stores the second data in the first memory 160, 2 data can be controlled to be output.

For example, when the second data is the handwriting input 910, the first control unit 180 receives the handwriting input 910 from the stylus pen 300 and, as in the example shown in FIG. 9A, So that the received handwriting input 910 is displayed. When it is determined that the attribute of the second data to be received from the stylus pen 300 is related to handwriting to display the handwriting input 910 received from the stylus pen 300 on the first touch screen, May automatically set the mobile terminal 100 to the handwriting input 910 mode.

9A, the handwriting input 910 received from the stylus pen 300 is displayed on the first touch screen so that the handwriting input 910 created through the other mobile terminal 100 can be easily copied can do. Further, the user can input the handwriting input 910 to the first touch screen by simply touching the stylus pen 300 on the first touch screen without moving the stylus pen 300 along the predetermined trajectory.

9A, when the second data is received from the stylus pen 300, the first control unit 180 performs control such that a pop-up window 920 indicating completion of reception of the second data is output You may.

If the second data is an image file such as a capture image, the first control unit 180 receives the image file 930 from the stylus pen 300 and, as in the example shown in FIG. 9B, (930) is output. Although not shown, when the second data is a multimedia file such as a moving picture file or a music file, the first controller 180 plays back a moving picture file or a music file after receiving the second data or after receiving the second data Output.

When the reception of the second data from the stylus pen 300 is completed, the pop-up window 920 and the like can be output as described above with reference to FIG. 9A.

When the second data is an execution command of a predetermined application, the first control unit 180 receives an execution command of a predetermined application from the stylus pen 300, and causes the predetermined application to be automatically executed as in the example shown in FIG. 9C (E-mail application is illustrated as being executed in Fig. 9C).

If a predetermined application corresponding to an execution command is not installed in the mobile terminal 100, the first controller 180 controls the display of a setup screen for installing a predetermined application to induce a download of a predetermined application . Specifically, after the first control unit 180 accesses the application providing server, the first control unit 180 may control to display an installation screen of a predetermined application. Here, the application providing server is not only an application providing server operated by an OS manufacturer such as an App store of Apple, a Play store of Google, a market of MS company, Appworld of Blackberry, SK Telecom, SK Telecom, SK Telecom, SK Telecom, KT Telecom, LG U + In addition to the businesses listed above, a server that can assist with the application installation of the mobile terminal 100 may be included in the category of the application providing server.

If the application providing server can not provide the installation file of the predetermined application to the mobile terminal 100, for example, if the application providing server does not have the installation file of the predetermined application, the first control unit 180 The first touch screen may be controlled so that a pop-up window indicating that the predetermined application can not be executed or the predetermined application can not be installed is displayed.

9, when the first control unit 180 receives the second data from the stylus pen 300, the first control unit 180 may control the operation of the mobile terminal 100 according to the type of the received second data have. For example, when the second data is a handwriting input, the first controller 180 can set the handwriting input mode to the mobile terminal 100. When the second data is a multimedia file such as an image file, a moving picture file, and a music file , It is possible to attempt automatic reproduction of a multimedia file that is being received or has been received.

In order to allow the first controller 180 to more smoothly control the operation of the mobile terminal 100, the header area of the first data and the second data includes an identifier indicating the type of the first data and the second data May be recorded. In this case, the first control unit 180 can predict an operation to be performed in the future by checking the header area of the second data. For example, when it is determined that the second data is related to the handwriting input through the confirmation of the header area of the second data, the first controller 180 may set the handwriting input mode to the handwriting input mode have. As another example, when it is determined that the second data is a moving image file, the first control unit 180 may execute the moving image playback application before completing the reception of the second data.

In the above example, the touch input of the stylus pen 300 for transmitting the second data to the mobile terminal 100 may include at least one of a contact touch and a proximity touch. That is, the second control unit 340 of the stylus pen 300 determines whether or not the stylus pen 300 is touched to the mobile terminal 100 and the stylus pen 300 is touched to the mobile terminal 100 at least In one case, it is possible to control the second data to be transmitted to the mobile terminal 100.

According to another example of the present invention, the stylus pen 300 distinguishes between the case where the stylus pen 300 is touched with the first touch screen of the mobile terminal 100 and the case where the stylus pen 300 is touched with the first touch screen of the mobile terminal 100, The second data may be controlled to be transmitted only when the mobile terminal 100 is contacted. At this time, the second control unit 340 of the stylus pen 300 distinguishes between the case where the stylus pen 300 is touched and the case where the stylus pen 300 is touched to the first touch screen, A preview of the second data may be transmitted to the mobile terminal 100 and the second data may be transmitted to the mobile terminal 100 only when the stylus pen 300 is touched to the first touch screen. Here, the preview of the second data may be a thumbnail of an image file or a moving image file, or may be an icon of a predetermined application to be executed according to an application execution command. The preview of the second data may be generated by the second control unit 340, but may be transmitted to the stylus pen 300 together with the first data in the example of FIG. 8 previously.

The first data of the mobile terminal 100 is transmitted to the stylus pen 300 and the mobile terminal 100 receives the second data stored in the stylus pen 300 as in the example shown in Figs. Thus, data can be easily shared between terminals. That is, when the first data of the mobile terminal 100 is to be shared with another terminal, the stylus pen 300 set in the data transmission / reception mode is touched to the first touch screen of the mobile terminal 100, By touching the received stylus pen 300 to another terminal, the first data can be transmitted to the other terminal.

Conversely, when the stylus pen 300 receiving the second data from another terminal is touched to the first touch screen of the mobile terminal 100, the second data stored in the stylus pen 300 can be received, It is possible to easily share the second data stored in the second memory.

When the second control unit 340 of the stylus pen 300 completes the transmission of the second data or transmits the second data over a predetermined number of times, the second control unit 340 controls the second data to be deleted can do. Deletion of the second data is for switching the data area of the second memory 330 to the blank state so that the stylus pen 300 can switch from the mobile terminal 100 to the state capable of receiving the first data.

As another example, the second control unit 340 may control the second data to be deleted when a delete command is input through the second user input unit 350. [

The stylus pen 300 transmitting and receiving the first data or the second data from the mobile terminal 100 can display the operation state of the stylus pen 300 through the second display unit 370. [ When the second display unit 370 includes the light emitting module, the second control unit 340 displays the operation state of the stylus pen 300 based on at least one of the light emitting state, the lightness, the color, and the light emitting area of the light emitting module . Referring to FIG. 10, the display of the operation state of the stylus pen 300 through the second display unit 370 will be described in detail. For convenience of explanation, it is assumed that the second display portion 370 includes a light emitting module.

FIG. 10 is an exemplary view for explaining an operation state of the stylus pen through the second display section. FIG.

First, the second controller 340 may distinguish between a case of being in a blank state and a case of being not in a data area of the stylus pen 300 based on whether or not the light emitting module is turned on. For example, as in the example shown in FIG. 10A, the second controller 340 controls the light emitting module to be in an unlit state when the data area of the stylus pen 300 is empty, When the data area is not in the blank state, the light emitting module can be controlled to be in the lighting state.

Although not shown, the second controller 340 may express whether the data area is empty based on the lighting color or brightness of the light emitting module. For example, when the data area of the stylus pen 300 is empty, the second controller 340 controls the light emitting module to emit light of the first color. When the data area of the stylus pen 300 is not empty The light emitting module may emit light of a second color, thereby expressing the blank state of the data area. As another example, when the data area of the stylus pen 300 is in a blank state, the second controller 340 sets the brightness of the light emitting module to the first light intensity. If the data area of the stylus pen 300 is not blank The brightness of the light emitting module may be set to the second light intensity.

When transmission or reception of the first data or the second data occurs between the stylus pen 300 and the mobile terminal 100 to indicate that the stylus pen 300 is performing wireless communication with the mobile terminal 100, The second controller 340 may emit the light emitting module in a color different from that shown in FIG. 10A. For example, if the light emitting module emits light of a first color when data exists in the data area, the second control unit 340 controls the operation of the stylus pen 300 when the stylus pen 300 receives the first data from the mobile terminal 100, The light emitting module can be controlled to emit light in the second color during transmission of the second data to the light emitting module 100.

At this time, the second controller 340 may display the reception ratio of the first data or the transmission ratio of the second data through the light emitting area of the light emitting module. For example, as in the example shown in FIG. 10B, the control unit can control the emission area of the light emitting module to increase as the amount of the first data received or the amount of the second data transmitted approaches 100% of the target amount. In order to distinguish the case where the stylus pen 300 receives the first data from the mobile terminal 100 and the case where the stylus pen 300 transmits the second data to the mobile terminal 100, The light emitting area of the light emitting module is controlled to be expanded in the first direction, and when the second data is transmitted, the light emitting area of the light emitting module is controlled to be expanded in the second direction opposite to the first direction have.

The operation state display of the stylus pen 300 using the light emitting module illustrated in FIG. 10 is only an example of how the stylus pen 300 according to the present invention can be applied. It is needless to say that the operation state of the stylus pen 300 may be displayed through the light emitting module in a different manner from the example shown in FIG.

Further, when the second display unit 370 includes a display module, the second control unit 340 may display the operation state of the stylus pen 300 through the display module.

According to an embodiment of the present invention, when the mobile terminal 100 transmits the first data to the stylus pen 300, the first control unit 180 determines that the stylus pen 300 is authorized to receive the first data It may be determined whether or not the first data transmission step S605 is in progress.

For example, when the stylus pen 300 does not have the reception right, the first controller 180 can control the first touch screen so that the transmission of the first data is not performed even if the stylus pen 300 is touched. The determination of whether or not the first data is transmitted based on the reception right of the stylus pen 300 is intended to prevent data from being transmitted indiscriminately to the unauthorized user.

The receiving authority of the stylus pen 300 will be described in detail with reference to the exemplary diagrams of FIG. 11 and FIG.

11 is an exemplary diagram for explaining setting of the reception authority to the stylus pen. 11A, when the user desires to give the reception authority to the stylus pen 300, the first control unit 180 displays a pop-up window for guiding the touch of the stylus pen 300 to which the reception right is to be given, (1110) is displayed.

11B, when the stylus pen 300 to which the reception right is to be granted is touched, the mobile terminal 100 transmits the reception right to the stylus pen 300 through wireless communication with the stylus pen 300. [ By receiving and storing the identification information, the receiving authority can be given to the stylus pen 300.

11C, the first controller 180 may control the display of a popup window 1120 indicating that the reception authorization is completed (step < RTI ID = 0.0 > .

Here, the identification information of the stylus pen 300 may be an ID (identification) unique to the stylus pen 300, an identifier such as an NFC module or a Bluetooth module, or the like. The unique ID of the stylus pen 300 may be given in the manufacturing process of the eyedropper pen or may be a temporary ID given by the user.

Thereafter, when the stylus pen 300 to receive the first data touches the first touch screen, the first controller 180 determines whether or not the receiving authority is given to the stylus pen 300, The first data can be transmitted. Specifically, the first control unit 180 receives the identification information of the stylus pen 300, compares the received identification information with the identification information stored in the memory, and determines whether or not the reception right is set in the stylus pen 300 can do.

The first control unit 180 may transmit the first data to the stylus pen 300 when the first control unit 180 determines that the receiving authority is given to the stylus pen 300. [ On the other hand, when it is determined that the two are inconsistent and the stylus pen 300 is not authorized to receive the data, the first control unit 180 may suspend the transmission of the first data.

The operation of the mobile terminal 100 when the stylus pen 300 having no reception right is touched on the first touch screen will be described in detail with reference to FIG.

12 is an exemplary view for explaining the operation of the mobile terminal when a stylus pen having no reception right is touched. When the stylus pen 300 having no reception right touches the first touch screen, the first control unit 180 does not set the reception right to the stylus pen 300, as in the example shown in FIG. 12A, A popup window 1210 for notifying that the first data can not be transmitted can be displayed.

As another example, when the stylus pen 300 having no reception authority is touched, the first control unit 180 may request input of a password, as in the example shown in FIG. 12B. At this time, if the password input by the user matches the pre-set password, the first control unit 180 can transmit the first data to the stylus pen 300 even if the receiving right is not given to the stylus pen 300 .

11 and 12 illustrate that the identification authority can be given to the stylus pen 300 based on the identification information of the stylus pen 300. [ 11 and 12, the first control unit 180 may determine whether to transmit the first data based on the sharing right of the file and folder stored in the mobile terminal 100. [

For example, when the first data selected by the stylus pen 300 is a file to which a sharing right is assigned or a file belonging to a folder to which sharing authority is assigned, the first control unit 180 controls the first Data can be controlled to be transmitted.

On the contrary, if the first data selected by the stylus pen 300 is a file belonging to a file having no sharing right or a folder having no sharing right, the first control unit 180 can suspend the transmission of the first data .

In this case, the first control unit 180 may display a pop-up window informing that the first data can not be transmitted, as in the example shown in Fig. 12A, It is possible to determine whether or not the first data is transmitted.

The first control unit 180 may use the home screen of the mobile terminal 100 in setting the sharing right of files and folders stored in the mobile terminal 100. [ For example, when the home screen of the mobile terminal 100 is composed of a plurality of pages, the first controller 180 may set at least one of the plurality of pages as a shareable page. The first control unit 180 distinguishes between the case where the stylus pen 300 is touched and the case where the stylus pen 300 is touched with the page that can not be shared with the page that can be shared and the stylus pen 300 is touched The first data may be transmitted to the stylus pen 300 only when the first data is transmitted.

When the stylus pen 300 is touched to a non-shareable page, a pop-up window indicating that the first data can not be transmitted is displayed, as in the example shown in FIG. 12A, or, as in the example shown in FIG. 12B, By receiving the input of the password, it can be determined whether or not the first data is transmitted.

The mobile terminal 100 according to an embodiment of the present invention distinguishes the touch of the stylus pen 300 from the proximity of the stylus pen 300 and displays whether the first data can be transmitted when the stylus pen 300 is touched proximately, When the pen 300 is touched, the first data may be transmitted according to whether or not the first data can be transmitted. Here, whether or not the first data can be transmitted can be expressed by a message window indicating whether the first data can be transmitted and a color change of the first data. Specifically, when the first data can be transmitted to the stylus pen 300, the first controller 180 responds to the proximity touch of the stylus pen 300 to display a pop-up window in which a message " transmittable " , If the first data can not be transmitted to the stylus pen 300, the first controller 180 may display a pop-up window in which a message " no transmission " is inputted in response to the proximity touch of the stylus pen 300 .

Alternatively, when the proximity touch position of the stylus pen 300 is an icon of a predetermined application or a predetermined image, the first control unit 180 may execute an execution command of a predetermined application through an icon color change of an application or an image color change It is also possible to indicate whether the image file can be transmitted or not.

As described above, the data that can not be transmitted to the stylus pen 300 may include at least one of a file to which the copyright protection technology is applied, a file that does not have sharing authority, and a file that belongs to a folder that does not have sharing authority.

According to the present invention, the first controller 180 may control the transmission of the first data or the reception of the second data only when the stylus pen 300 is in contact with the first touch screen. For example, when the stylus pen 300 is touched while the first data is being transmitted from the mobile terminal 100 to the stylus pen 300, the first controller 180 may control the transmission of the first data to be stopped have. As another example, when the stylus pen 300 is disengaged while the mobile terminal 100 is receiving the second data from the stylus pen 300, the first controller 180 controls to stop the reception of the second data .

If the transmission of the first data or the reception of the second data is interrupted, the first controller 180 may control the first touch screen to display a pop-up window for notifying that transmission of the first data or the second data is stopped .

As another example, even if the stylus pen 300 is disconnected from the first touch screen, if the stylus pen 300 is within the wireless communicable range, the first control unit 180 may transmit the first data or the second data You can also control to continue. That is, if the stylus pen 300 is in the range where wireless communication is possible after the start of the first data transmission or the second data reception, even if the stylus pen 300 is disconnected from the first touch screen, .

In the above example, the stylus pen 300 can be set to either the normal mode or the data transmission / reception mode based on a user input to the user input unit 350 of the stylus pen 300. However, determination of the normal mode and the data transmission / reception mode does not necessarily have to be performed by the stylus 300, as in the above-described example.

The first control unit 180 may set the mobile terminal 100 to the normal mode or the data transmission / reception mode based on the user input to the mobile terminal 100. In this case, If the stylus pen 300 touches the first touch screen while the mobile terminal 100 is set to the normal mode, step S603 of FIG. 6 will be performed. If the mobile terminal 100 is set to the data transmission / reception mode If so, step S604 of FIG. 6 may be performed.

As another example, the first control unit 180 may determine the normal mode or the data transmission / reception mode based on whether the stylus pen 300 is touched or approximated to the first touch screen. For example, if the stylus pen 300 touches the first touch screen, the first controller 180 determines that the stylus pen 300 is in the normal mode operation and can perform step S603 of FIG. 6, If the first touch screen is touched in proximity, it is determined that the data communication mode is the data transmission / reception mode, so that the step S604 of FIG. 6 can be controlled.

According to one embodiment of the present invention, the above-described method (operation flow diagram) can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .

The mobile terminal 100 and the stylus pen 300 described above are not limited in the configuration and the method of the embodiments described above, but the embodiments can be applied to all of the embodiments Or some of them may be selectively combined.
