The electronic device 10 refers to a device disposed around the touch panel 20 and driven by a clock signal or a drive signal to generate an electromagnetic wave. For example, since the touch panel 20 is generally disposed on a display panel that displays an image, the electronic device 10 may be a display panel, and may be a voltage supply unit for supplying a voltage to the touch panel 20 And may be an electronic device 10 disposed outside the touch sensing device 100 including the touch panel 20 to generate electromagnetic waves.

The electronic device 10 may be a display panel. The display panel is a panel for displaying an image. The display panel includes a liquid crystal display panel, an electrophoretic display panel, an organic light emitting diode panel, an LED panel, and an electro luminescent display panel Panel, a field emission display panel, a surface-conduction electron-emitter display panel, a plasma display panel (PDP), or a cathode ray tube (CRT) display panel. The touch panel 20 may be stacked on one side of the display panel. For convenience of description, the electronic device 10 is described as being a display panel. However, the present invention is not limited thereto. For example, the electronic device 10 may generate electromagnetic waves outside the touch panel 20, It is apparent that the electronic device 10 can be employed.

The display panel may be a liquid crystal display panel driven using a clock signal. For convenience of description, the electronic device 10 is described as being a liquid crystal display panel of a display panel. However, the present invention is not limited thereto and various types of display panels driven by a clock signal or a driving signal may be employed. Do.

The touch panel 20 is disposed adjacent to the electronic device 10 and can receive a user's touch signal. Referring to FIG. 2, the touch panel 20 is disposed on a display panel for displaying an image, and receives a user's touch signal. The touch panel 20 is a panel that receives a user's touch signal, and may be implemented in various forms, and is not proposed in a specific form. For example, the touch panel 20 may have a two-layer structure, wherein the touch sensor includes a plurality of drive electrode traces intersecting a plurality of sense electrode traces (e.g., traces extending in the X axis direction) (E. G., Traces extending in the Y-axis direction). ≪ / RTI > In addition, the touch panel 20 may be implemented with a touch panel 20 having coplanar single layer touch sensors fabricated on a single side of a single layer of the substrate. Each of the drive and sense electrode traces may be fabricated as shapes in a first axial direction and divided electrodes in a second axial direction, And the electrodes formed on the same first axis among the plurality of divided electrodes in the second axial direction may be connected together using separate metal wires in the boundary region of the touch panel 20 have.

The touch sensor chip 30 can receive a sensing signal from the touch panel 20 by applying a driving signal to the touch panel 20. For example, the touch sensor chip 30 may apply a driving signal to the driving electrode traces of the touch panel 20, and receive sensing signals from the sensing electrode traces of the touch panel 20. The touch sensor chip 30 can determine the touch position of the user based on the driving signal applied to the touch panel 20 and the sensing signal input from the touch panel 20. [

The touch sensor chip 30 may be mounted on the touch panel 20 as shown in FIG. 2 and disposed on the same plane as the driving electrode traces and sense electrode traces of the touch panel 20 . In some embodiments, the touch sensor chip 30 may be mounted on a separate circuit board other than the touch panel 20, and the circuit board on which the touch sensor chip 30 is mounted may be electrically connected to the touch panel 20 .

The lock control system according to embodiments of the present invention may be an apparatus including a touch screen such as the touch sensing apparatus 100 described with reference to FIGS. For example, the lock control system can unlock the touch screen based on the number of touches simultaneously recognized on the touch panel 20. [

3 is a diagram illustrating an example of a process in which a user inputs a password in an embodiment of the present invention. 3, when the password for releasing the lock mode (for example, the lock state of the touch screen or the security state of the application) in the lock control system is preset to "4213 ", the user enters the password (The first process 310, the second process 320, the third process 330, and the fourth process 340).

The first step 310 may be a process in which a user touches four fingers simultaneously on the touch screen 350. [ For example, the touch screen 350 may correspond to the touch panel 20 described with reference to FIGS. 1 and 2. FIG. In this case, the touch sensor chip 30 can recognize four objects through touch by four fingers. In other words, the lock control system can recognize the number of objects '4'. At this time, the locked control system can confirm how many objects are recognized on the touch screen 350 regardless of the positions of the objects.

The second process 320 may be a process in which a user touches two fingers on the touch screen 350 at the same time. Also in this case, the touch sensor chip 30 can recognize two objects through touch by two fingers, and the lock control system can recognize '2' which is the number of objects.

The third process 330 may be a process in which a user touches one finger on the touch screen 350. In this case, the touch circuit chip 30 can recognize one object by touching with one finger. At this time, the lock control system can recognize '1' which is the number of objects.

The fourth process 340 may be a process in which a user touches three fingers on the touch screen 350 at the same time. In this case, the touch sensor chip 30 can recognize three touches by touching with three fingers, and the lock control system can recognize '3', which is the number of objects.

At this time, the lock control system can proceed with the process for password confirmation when the first to third processes 310 to 340 are continuously generated within a predetermined time interval. For example, if the predetermined time interval is 3 seconds, the lock control system may detect the number of taps 2 'through the second process 320 within 3 seconds after the number' 4 'of taps is recognized through the first process 310 'Should be recognized, it can be judged as a process for inputting consecutive passwords. If the number '2' of touches is not recognized in the second step 320 after 3 seconds after the first step 310, the lock control system initializes the process for confirming the input of the password, And can provide a guidance message to the user.

In the embodiment of FIG. 3 described above, the lock control system can confirm the number such as "4 → 2 → 1 → 3" according to the sequence of consecutively recognized numbers of objects, and confirms the confirmed number with the password "4213" Can be compared. At this time, if the confirmed number and the password match each other, the lock control system can release the lock mode.

In such an embodiment, the lock control system may not consider the location at which the user generates a touch. Accordingly, it is possible to solve the problems of the prior art in which the user has to touch with a particular mark.

The process of determining the number of objects in the lock control system may utilize one or more of various known techniques for recognizing multi-touch. For example, Korean Patent Laid-Open No. 10-2009-0121576 (entitled " Method and Apparatus for Detecting Multiple Touch Inputs) " discloses a method and apparatus for sensing two or more contact inputs without increasing the number of electrodes Lt; / RTI > As another example, Korean Patent Laid-Open No. 10-2010-0116281 (titled " contact detection panel and apparatus capable of sensing a plurality of touch inputs "), in order to accurately determine the positions of a plurality of touch inputs, Analyzes the image by sensitivity, and judges whether the group images are classified into the same group or a separate group, and confirms how many touches are generated at the same time.

FIG. 4 is a block diagram for explaining an internal configuration of a lock control system in an embodiment of the present invention, and FIG. 5 is a flowchart showing a lock control method in an embodiment of the present invention.

The lock control system 400 according to the present embodiment may include a touch sensing device 10, a processor 410, a bus 420, a network interface 430 and a memory 440, as shown in FIG. have. The memory 440 may include an operating system 441 and a lock control routine 442. The processor 410 may include a password management unit 411, an object number verification unit 412, a password matching unit 413, and a lock mode release unit 414. [ In other embodiments, the lock control system 400 may include more components than the components of FIG. However, there is no need to clearly illustrate most prior art components. For example, the lock control system 400 may include other components such as a camera, an acceleration sensor, or a vibration motor.

The memory 440 may be a computer-readable recording medium and may include a permanent mass storage device such as a random access memory (RAM), a read only memory (ROM), and a disk drive. Also, the memory 440 may store program codes for the operating system 441 and the lock control routine 442. [ These software components may be loaded from a computer readable recording medium separate from the memory 440 using a drive mechanism (not shown). Such a computer-readable recording medium may include a computer-readable recording medium (not shown) such as a floppy drive, a disk, a tape, a DVD / CD-ROM drive, or a memory card. In other embodiments, the software components may be loaded into the memory 440 via the network interface 430 rather than from a computer readable recording medium. For example, the lock control routine 442 may be loaded into the memory 440 based on the program installed by the files that the developers provide over the network.

The bus 420 may enable communication and data transfer between the components of the lock control system 400. The bus 420 may be configured using a high-speed serial bus, a parallel bus, a Storage Area Network (SAN), and / or any other suitable communication technology. Information about the position of the touch recognized by the touch sensing device 10 or information on the number of objects is transmitted to the processor 410 via the bus 420 and used by the processor 410 or by the bus 420 to the memory 440 and stored in the memory 440. Information stored in the memory 440 may also be transferred to the processor 410 via the bus 420. [

Network interface 430 may be a computer hardware component for coupling lock control system 400 to a computer network. The network interface 430 may connect the lock control system 400 to the computer network via a wireless or wired connection.

The processor 410 may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input / output operations of the lock control system 400. The instructions may be provided to the processor 410 by the memory 440 or the network interface 430 and via the bus 400. The processor 410 may be configured to execute program codes for the password management unit 411, the object number verification unit 412, the password matching unit 413, and the lock mode release unit 414. [ Such program code may be stored (e. G., A lock control routine 442) in a recording device, such as memory 440. [

At this time, the password management unit 411, the object number confirmation unit 412, the password matching unit 413, and the lock mode release unit 414 included in the processor 410 perform the steps 510 to 540 of FIG. 5 Lt; / RTI >

In step 510, the password management unit 411 can manage a password composed of at least one number used for releasing the lock mode. For example, the password management unit 411 can store and manage the password entered and set by the user in the memory 440. [

In step 520, the number-of-objects check unit 412 can confirm the number of objects simultaneously recognized on the touch screen in the lock mode. As described above, a plurality of objects can be recognized simultaneously according to a single touch on the touch screen. For example, the touch sensing device 10 may provide information about the position at which the object is recognized, as well as information about the number of simultaneously recognized objects. At this time, the number-of-objects check unit 412 can confirm the number of objects based on the information provided by the touch sensing apparatus 10. [

In step 530, the password matching unit 413 may compare the number that is determined based on the number of objects with the number that constitutes the password. For example, when the number of objects is '3', the number to be checked can be confirmed to be 3, and the password matching unit 413 can check whether the number constituting the password is three.

If there are a plurality of numbers constituting the password, the object number confirmation unit 412 simultaneously recognizes the plurality of touches continuously generated within the predetermined time interval in the lock mode state at step 520 You can see the number of objects. For example, assume that the predetermined time interval is 3 seconds. The number of objects check unit 412 can confirm the number of objects simultaneously recognized by a single touch and then check the number of simultaneously recognized objects for another touch continuously generated within 3 seconds. If the password is composed of four numbers, the object number confirmation unit 412 can confirm the number of objects for four touches continuously input within a time interval of 3 seconds. If the next touch does not occur after 3 seconds, the process for confirming the password can be initialized.

In step 540, the lock mode releasing unit 414 can release the lock mode if the number of the identified number matches the number of the password. For example, in the embodiment of FIG. 3, if the password is set to "4213 ", the lock mode release section 414 can release the lock mode if the identified number is consecutively 4, 2, have.

The number of the numbers constituting the password can be variously set according to the selection of the user to the extent allowed by the lock control system 400, and the maximum size of the numbers constituting the password can be variously set. But it is not limited to 5 or less (input by one hand) in that the number of digits is inputted by using the number of fingers.

Although only the configuration for releasing the lock mode has been described in the above embodiment, the lock control system 400 can execute the specific application at the same time of releasing the lock mode, rather than simply releasing the lock mode.

6 is a diagram illustrating an example of a process of executing a specific application at the same time when a lock mode is released according to an embodiment of the present invention. In FIG. 6, a first dotted box 610 represents a plurality of passwords, and a second dotted box 620 represents a plurality of applications. If the number of identified objects is "3", "3", "3", or "2" as shown in FIG. 6, Gt; 630 < / RTI > In this case, the lock control system 400 described with reference to FIG. 4 can drive the third application, which is an application corresponding to the password "3332" 630, at the same time as the release of the lock mode. For example, if the lock mode indicates the lock status of the touch screen and the third application is an application related to the recent call list, if the user enters a password "3332" (630) The user can release the locked state of the screen and simultaneously drive the third application to display the recent call list on the touch screen.

Of course, a password for only releasing the lock mode may be set, and another function and the password of the lock control system 400 may be matched. For example, the function for changing the vibration mode to the sound mode simultaneously with the release of the lock mode may be matched with a specific password.

For this embodiment, the password management unit 411 can manage a plurality of different passwords in association with functions associated with a plurality of passwords at step 510. [ In this case, in addition to the steps 510 to 540 shown in FIG. 5, the lock control method described with reference to FIG. 5 executes a function associated with a password used for releasing the lock mode when the lock mode is released ). This unillustrated step may be performed by a function execution unit (not shown) that the processor 410 of the lock control system 400 further includes.

In another embodiment, instead of using a plurality of passwords, one password and a plurality of drive numbers for driving an application may be used individually.

7 is a diagram illustrating another example of a process of executing a specific application at the same time as releasing the lock mode in an embodiment of the present invention. 7 shows an example in which drive numbers are set separately from the password "3332" (710). The third dashed line box 720 indicates driving numbers, and the fourth dashed box 730 indicates a plurality of applications. At this time, each of the drive numbers may be associated with respective applications. If the number of identified objects is "3", "3", "3", "2", "3" as shown in FIG. 7, the previous four numbers "3" "3 "," 2 "can be used for matching the password, and the last one number" 3 " At this time, the lock control system 400 can release the lock mode by matching the previous four numbers "3", "3", "3", "2" The third application can be executed by matching with the drive number "3" (740). In FIG. 7, an example in which the driving number is composed of one number is described, but it may be implemented by two or more numbers.

For this embodiment, the password management unit 411 can further manage the driving numbers for driving other functions in step 510 in association with the corresponding functions. Also, the password matching unit 413 may compare the numbers of some of the plurality of objects identified for each of the plurality of touches with the password at step 530, and compare the remaining numbers to the driving numbers. 5, in addition to the steps 510 to 540 shown in FIG. 5, when the lock mode is canceled, a drive number matched with the remaining ones of the drive numbers is checked, (Not shown) of executing a function associated with the number. This unillustrated step may be performed by a function execution unit (not shown) that the processor 410 of the lock control system 400 further includes.

In the above-described embodiments, the lock control system is embodied as an apparatus including a touch screen such as the touch sensing apparatus 100. However, the lock control system may be applied to the touch sensor chip 30 ). For example, when the touch sensor chip 30 is mounted on the touch sensor chip 30 so that the password management unit 411, the object number confirmation unit 412, the password matching unit 413, and the lock mode release unit 414 are included, .

In the above embodiments, embodiments of releasing the lock mode based on the number of objects have been described, but this can be extended to execute a specific function of the device based on the number of objects. 8 and 9 illustrate embodiments for performing specific functions of the device based on the number of objects.

The apparatus 800 according to the present embodiment may include a processor 810, a bus 820, a network interface 830, a memory 840 and a touch screen 850, as shown in FIG. The memory 840 may include an operating system 841 and a function execution routine 842. The processor 810 includes a drive number management unit 811, an object number confirmation unit 812, a comparison unit 813, 814 < / RTI > In other embodiments, the device 800 may include more components than the components of FIG. However, there is no need to clearly illustrate most prior art components. For example, the device 800 may include other components such as a camera, an acceleration sensor, or a vibration motor.

The processor 810, the bus 820, the network interface 830, the memory 840 and the touch screen 850 are connected to the processor 410, the bus 420, the network interface 430, the memory 440 and the touch sensing device 10, respectively, and will not be described repeatedly since they operate similarly.

In step 910, the drive number management unit 811 may manage a drive number composed of at least one number used for executing the function of the apparatus in association with the function. For example, the drive number management unit 811 can store and manage the drive number input by the user or the preset drive number in the memory 840 in association with information on the corresponding function. As a more specific example, the driving number management unit 811 may manage the driving number '1234' in step 910 in association with the function of executing the contact application.

In step 920, the number-of-objects check unit 812 can check the number of objects simultaneously recognized on the touch screen 850. Since the number of objects simultaneously recognized in one touch has already been described in detail, the repetitive description will be omitted.

In step 930, the comparing unit 813 may compare the number that is determined based on the number of objects with the number that constitutes the driving number. For example, if the number of objects is '3', the number to be checked can be identified as 3, and the comparing unit 813 can confirm that the number constituting the driving number is three.

If there are a plurality of numbers constituting the driving number as in the example of '1234' described above, the number-of-objects checking unit 812 may check the number of the touches continuously generated within the predetermined time interval in step 920 , The number of objects recognized at the same time for each touch can be confirmed. For example, assume that the predetermined time interval is 3 seconds. The number-of-objects check unit 812 can check the number of objects recognized at the same time through one touch, and then confirm the number of objects simultaneously recognized for another touch continuously generated within 3 seconds. If the driving number is composed of four numbers, the object number confirmation unit 812 can confirm the number of objects for four touches continuously input within a time interval of 3 seconds. If the next touch does not occur for three seconds, the process for identifying the drive number may be initiated.

In step 940, the function execution unit 814 can execute a function corresponding to the drive number when the number of the identified number matches the number of the drive number. For example, if the drive number is present and the identified number is 1, 2, 3, 4 consecutively as in the example of '1234' described above, the function execution unit 814 determines that the drive number '1234' Depending on the function, you can launch the Contacts application.

In another embodiment, the drive number management unit 811 can manage a plurality of drive numbers in association with a plurality of functions of the apparatus, respectively. In this case, the function execution unit 814 can confirm the driving number that matches the identified number, and execute the function associated with the identified driving number among the plurality of functions. As a concrete example, the contact application is executed for the drive number '1234', the application for the phone call is executed for the drive number '2341', the vibration mode is changed to the sound mode for the drive number '3412' Can be used. The number of numbers constituting the driving number may be set to various numbers as well as the above-mentioned password.

As described above, according to the embodiments of the present invention, it is possible to release the lock mode (for example, the lock state of the touch screen or the security state of the application) based on the number of objects simultaneously recognized on the touch generated on the touch screen have. Further, the present invention is not limited to the release of the lock mode, and it is also possible to perform a specific function of the device based on the number of objects simultaneously recognized on the touch generated on the touch screen.
