4 to 8 are views for explaining a structure of a display unit capable of fingerprint recognition in a portable terminal according to an embodiment of the present invention.

In the present invention, a case in which a pointer such as a pen is touched by the display unit 151 is defined as a general touch input, and a touch input including fingerprint information of a human body such as a finger of a user is defined as a fingerprint touch input .

In order to perform the fingerprint touch input, the display unit 151 must be capable of fingerprint recognition. The structure of the display unit 151 capable of fingerprint recognition can be classified into a form in which a photo sensor is inserted in an LCD module (LCD with Embedded Photo Sensor) or a form in which a photosensor is placed on an LCD module LCD) or the like.

Therefore, as shown in FIG. 4 (a), the display unit 151 has a structure in which an internal structure, an LCD module with a photosensor inserted therein, a window, and a touch sensor are stacked in this order, , A structure in which a structure is built up in the order of an LCD module with a built-in photosensor, a touch sensor, and a window can be used. However, it is also possible to configure the touch sensor to be able to recognize the touch using the scan structure of the photo sensor without using the touch sensor. In this case, a structure in which a structure is built up from the inside, an LCD module in which a photosensor is inserted, and a window are stacked in this order can be used.

FIGS. 5 and 6 show a structure using a photo film sensor mounted on an LCD module (Scan Film with Photo Sensor over LCD). 5, only a transparent scan film is used. As shown in FIG. 5 (a), a structure in which structures are stacked in this order from an inner structure to an LCD module, a window, and a scan film, As shown in FIG. 5 (b), a structure in which structures are stacked in the order of an apparatus, an LCD module, a scan film, and a window can be used.

6 shows a form in which a scan film and a touch sensor are used together. As shown in FIG. 6 (a), a structure in which the structures are stacked from the inside in the order of an apparatus, an LCD module, a window, a touch sensor, and a scan film, as shown in FIG. 6 (b) As shown in FIG. 6 (c), a structure in which a structure is stacked in the order of an apparatus, an LCD module, a scan film, a window, and a touch sensor may be used.

Therefore, when the touch sensor is positioned inside the window, A laminated structure in the order of film, structure, stacked structure in the order of structure, LCD module, touch sensor, photosensor, and window, structure, structure, LCD module, photo sensor, touch sensor, and window are stacked in this order .

On the other hand, a transparent scan film is formed by mounting a photodiode and a transistor on a row and a column of a transparent material such as glass or a film, as shown in Fig. 7, It is a structure that can scan the contents placed on the film by using an electric signal which changes according to the amount. By using the scan function of the scan film, a black-and-white scan including fingerprint recognition is basically possible. In addition, by using the LCD located on the backside, it is possible to scan color by converting from LCD to R / G / B color, and combining the amount reflected by each light. In this case, the R / G / B color amount to be reflected by each pixel can be calculated through RGB combination by using a calculation table as shown in FIG. It is possible to combine these tables with matrices or functions instead of tables.

As described above, in the structure of the display unit 151 capable of fingerprint recognition, since a photo sensor can calculate coordinates according to the amount of change of light, it can be applied to touch or scan This is possible. Accordingly, the display unit 1510 can output a screen using an LCD. It may be an input device capable of inputs such as a single-touch input, a multi-touch input, and a scanning.

In addition, as described above, both the touch and the scan can be recognized by using the scan structure of the photo sensor without using the touch sensor. If the touch sensor is not used, it is possible to reduce the cost such as the cost of the parts, and it is possible to use the touch recognition with the existing stability when the touch sensor is mounted. Although the fingerprint recognition using the photo sensor has been described above as an example, a display unit capable of fingerprint recognition can also be configured by using various other methods such as a change in capacitance.

9 is a flowchart illustrating a method of controlling a mobile terminal according to an exemplary embodiment of the present invention. Referring to FIG. 9, fingerprint information recognized as at least one of the fingerprint information of each finger of the same user, fingerprint information of each user, and fingerprint information of a fingerprint recognition pattern is stored in the memory 160 (S200). That is, the fingerprint information can be stored for each finger, such as the thumb, index finger, stop finger, fingerprint fingerprint of the same user, and can be stored for each user as fingerprint information of the first user and fingerprint information of the second user. Further, different fingerprint recognition patterns can be stored according to the fingerprint recognition area for the finger of the same finger or the contact strength when the fingerprint is recognized.

At the time of storing the fingerprint information, whether or not fingerprint information related to the setting or release of the lock status can be set together with the operation mode to enter when the lock status is released. In addition, a separate menu can be provided for such setting.

Next, the controller 180 sets a protection state or a lock state in which no operation is performed for a touch input or general key input in response to a touch input or a key input for a predetermined period of time or according to a user's lock command or the like (S205). At this time, the locked state can be set only for a specific operation menu, not for the entire operation menu. Further, when the lock state is set, an icon indicating the setting of the lock state can be displayed, or an effect sound or a tactile effect can be generated.

When the locked state is set, the controller 180 determines whether there is a fingerprint touch input on the display unit 151 (S210). As described above, the fingerprint touch input refers to a touch input that includes fingerprint information, such as when the user's finger is touched on the display unit 151. [

As a result of the determination in step S210, if there is a fingerprint touch input, the controller 180 determines whether the fingerprint information input by the fingerprint touch input coincides with the fingerprint information registered as the release of the lock status among the fingerprint information stored in the memory 160 (S215).

 If it is determined in step S215 that the input fingerprint information matches the fingerprint information registered as the release of the locked state among the stored fingerprint information, the control unit 180 releases the locked state, So as to enter the operation mode (S220). Even in the case of releasing the locked state, it is possible to generate an effect sound or a tactile effect corresponding to the release of the locked state. In addition, if the fingerprint information input by the fingerprint touch input after the release of the lock state matches the fingerprint information registered in the setting of the lock state among the stored fingerprint information, the controller 180 may set the lock state again.

In this manner, the user can immediately enter the related operation mode at the same time as the lock state is released according to the set fingerprint touch input. In this embodiment, the case of releasing the lock state by the fingerprint touch input has been described, but a menu that can release the lock state by inputting a password or the like may be separately provided

10 is a flowchart illustrating a method of controlling a mobile terminal according to another embodiment of the present invention. 10, the fingerprint information recognized in at least one of the fingerprint information of each finger of the same user, the fingerprint information of each user, and the fingerprint information according to the fingerprint recognition pattern is stored in the memory 160 S300). At the time of storing the fingerprint information, a group or the like corresponding to the fingerprint information is set together.

Next, the control unit 180 displays a screen including the menu icon on the display unit 151 (S305).

In a state where a screen including the menu icon is displayed, the controller 180 determines whether there is a fingerprint touch input on the display unit 151 (S310). As described above, the fingerprint touch input refers to a touch input including fingerprint information as when the user's finger is touched.

If there is a fingerprint touch input, the controller 180 determines whether the fingerprint information input by the fingerprint touch input matches one of the fingerprint information stored in the fingerprint information (S315) And displays the screen including the icon on the display unit 151 (S320).

Examples of menu icons belonging to different groups include a menu icon corresponding to an operating system native application, a menu icon corresponding to an application downloaded from a webstore, a menu icon corresponding to an application preferred or designated by the user . In addition, in the process of displaying a screen including menu icons belonging to different groups, a specific screen effect can be displayed. Depending on the use environment, besides the screen effect, a sound effect or a tactile effect may be generated.

If there is no match between the stored fingerprint information and the inputted fingerprint information, the controller 180 causes the operation corresponding to the general touch input to be performed according to the fingerprint input area (S325).

If there is another user input other than the fingerprint touch input (S330), the control unit 180 controls the operation corresponding to the user input or the generated event to be performed (S335). If another operation mode is not selected, the control unit 180 causes the process after step S310 to be repeatedly performed (S340).

By this process, menu icons belonging to different groups can be displayed for each fingerprint information inputted by the fingerprint touch input.

Meanwhile, different control operations may be performed according to the fingerprint information input by the fingerprint touch input. Examples of the case where different control operations are performed according to the fingerprint touch input include a case where the user scrolls the screen at different speeds according to input fingerprint information or the screen is switched according to the fingerprint information of the scroll bar, the up / down / right / left / . That is, even if the fingerprint touch input is performed by the same user, it can be configured to operate at different scrolling speeds according to the fingerprint of each finger. For example, the thumb is very slow, the index is slow, the middle finger is fast, the finger is fast, and the baby is very fast. When the scroll bar is fingerprinted, the finger scrolls slowly. If you can scroll quickly. A thumbnail image such as a phone book, a message, and the like is displayed, a thumbnail image such as a photograph or a moving image is displayed, and the user scrolls slowly when the fingerprint is touched and the fingerprint is touched. Even when flicking is performed at a specific portion on the screen, flickering can be performed slowly using the index finger, and flickering can be performed quickly using the finger ring.

When the fingerprint is touched on the navigation key, the FF key, the RR key, the progressive bar, etc., the reproduction speed can be controlled at different speeds or the items can be switched according to the inputted fingerprint information. For example, when the finger is touched and dragged after the finger is touched with the finger, the playback speed is changed slowly in the corresponding direction, and when the finger is touched after dragging the fingerprint, the playback speed is rapidly changed.

Even if the same fingerprint is used, it is possible to control different fingerprints according to the fingerprint recognition time. For example, when the scroll bar is fingerprint-touched, the scroll speed is gradually increased as the fingerprint touch duration is increased.

You can also turn scrolling on or off automatically according to fingerprint recognition. For example, if the finger is touched at any point on the e-book screen by setting the index finger to the start of automatic scrolling and the stop is set to the automatic scroll, the finger is automatically scrolled at the specified speed, You can disable scrolling.

When the single fingerprint touch input is used, the fingerprint information can be recognized at the point where the fingerprint is touched. However, when the input to be dragged after touching the fingerprint is used, the fingerprint information can be recognized in various ways. For example, after recognizing only the fingerprint information of the point where the fingerprint is first touched or the first fingerprint is recognized successfully, the operation corresponding to the drag can be processed according to the recognized fingerprint. After recognizing the fingerprint of the first fingerprint touched point, it is possible to recognize the fingerprint according to the dragging and process the operation corresponding to the drag only when they match. Further, when the fingerprint of the first fingerprint touched point is recognized and the fingerprint of the end point of releasing the hand is recognized and the fingerprint information of the start point and the end point coincide with each other, the operation corresponding to the drag may be processed.

11 to 15 are diagrams for explaining a control method of a mobile terminal according to an embodiment of the present invention, together with a screen displayed on the display unit. 11 is a flowchart illustrating a process of entering a designated operation mode at the same time as releasing the locked state according to the fingerprint touch input according to an embodiment of the present invention.

When such a fingerprint touch input 535 exists, a screen 540 including a menu icon of a group set in advance corresponding to the fingerprint information for detection can be displayed as shown in FIG. 12 (b) .

For example, when a fingerprint is touched with an index finger, a menu icon corresponding to an operating system native application can be displayed. When a fingerprint is touched by stopping, a menu icon corresponding to an application downloaded from the Apple Web Store or the like is displayed, In the case of touching, a menu icon corresponding to a user's preferred or set application can be displayed.

When a screen including a menu icon belonging to another group is displayed, a specific screen effect, a sound effect, or a tactile effect may be generated.

13, when there is an input 555 for fingerprinting and dragging a specific area on the screen 560 on which the menu icon is displayed instead of touching the menu icon selection area, You can also display the group's menu icon.

FIGS. 14 and 15 are views for explaining a process of performing different control operations according to the fingerprint touch input according to an embodiment of the present invention.

14, in the case where there is an input 565 for touching and dragging a progress bar on the screen 560 for playing back a multimedia file, Can be performed. For example, when the fingerprint sensor is used for fingerprint detection, general search is performed by fingerprint touch input, and high speed search is performed by fingerprint touch input using stop. In addition, even if the FF key, the RW key, and other keys related to the control of the restoration operation are selected by the fingerprint touch input, they can be controlled in the same manner.

15 shows a case where the text viewer 570 has a flicking input 575 using a fingerprint touch. When there is a flicking input at a specific portion on the screen 570, the screen can be scrolled at different speeds depending on the finger used. For example, a flickering input using the index finger scrolls the screen slowly, and a flickering input using the stop can scroll the screen faster than when the detection is used. In addition, it is also possible to move the screen by different movement distances according to the fingerprint information by the fingerprint touch input.

Meanwhile, the present invention can be implemented as a processor-readable code on a processor-readable recording medium such as an MSM (Mobile Station Modem). The processor-readable recording medium includes all kinds of recording apparatuses in which data that can be read by the processor is stored. Examples of the recording medium readable by the processor include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device, and the like, and also a carrier wave such as transmission over the Internet.
