Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a schematic view of a touch sensing apparatus according to an embodiment of the present invention. 2 is an exploded perspective view of a touch sensing apparatus according to an embodiment of the present invention. Referring to FIGS. 1 and 2, the touch sensing apparatus 100 includes an electronic device 10, a touch panel 20, and a touch sensor chip 30.

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. The embodiment of FIG. 3 shows a case where 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 changed from "left direction to right direction (right arrow) It is presumed that the information is preset to four directional information such as "left to right direction", "upper (upper) to lower (lower) direction (↓)" and "lower right direction (↑)". In this case, the processes (the first process 310, the second process 320, the third process 330 and the fourth process 340) show an example of a process of a user inputting a password.

The first process 310 may be a process in which a user generates a touch-and-drag event in the left-to-right direction 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 the drag direction as "left to right direction (→)" in the touch and drag event. At this time, the lock control system can confirm only the direction of the drag regardless of the position at which the touch-and-drag event occurs on the touch screen 350. [ A method of recognizing the drag direction in the touch-drag event will be described in more detail with reference to FIG.

The second process 320 may be a process in which the user generates a second touch-and-drag event on the touch screen 350 from left to right. Also in this case, the touch sensor chip 30 can recognize the direction of the drag in the touch and drag event as "left to right direction (→)", and the lock control system can confirm the drag direction of the second touch and drag event have.

The third process 330 may be a process in which the user generates a third touch-and-drag event on the touch screen 350 in the downward direction. In this case, the touch circuit chip 30 can recognize the direction of the drag in the touch-drag event as "downward (↓)". At this time, the lock control system can confirm the drag direction of the third touch and drag event.

The fourth step 340 may be a process in which the user generates a fourth touch and drag event upward in the downward direction on the touch screen 350. In this case, the touch circuit chip 30 can recognize the direction of the drag in the touch-drag event as "upward (downward)" and the lock control system can confirm the drag direction of the fourth touch and drag event .

At this time, the lock control system can proceed with a process for confirming the drag direction when the first process 310 to the fourth process 340 are continuously generated within a predetermined time interval. For example, if the preset time interval is 3 seconds, the lock control system returns to the second process 320 again within 3 seconds after the "left to right direction (→)" is confirmed through the first process 310, From left to right (→) ", it can be judged as a process for inputting a continuous touch-and-drag event. If the "left to right direction" is not confirmed in the second step 320 after 3 seconds after the first step 310, the lock control system initializes the process for confirming the drag direction , And can provide a guidance message to the user.

In the embodiment of FIG. 3 described above, the lock control system determines whether or not the drag direction is continuously changed according to the recognized order, from "left to right", "left to right" ) "And" up direction (?) Under ", and can be compared with previously stored direction information. At this time, if the determined drag directions and pre-stored direction information 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-and-drag event. Accordingly, it is possible to solve the problems of the prior art in which the user has to touch with a particular mark.

4 is a diagram illustrating an example of a method for confirming a drag direction in a touch-and-drag event in an embodiment of the present invention. FIG. 4 shows a line 410 between the start coordinates and the end coordinates of a touch-and-drag event generated on the touch screen 400 in a visible manner. At this time, the lock control system can confirm the drag direction of the touch-drag event based on the angle 430 formed by the reference axis 420 and the straight line 410 in the virtual coordinate system having the start coordinates on the touch screen as the origin have. In the embodiment of FIG. 4, the reference axis 420 is an example of a positive x-axis, but the present invention is not limited thereto.

Here, let us consider an embodiment in which the lock control system uses four direction information such as right-to-left direction, left-right direction, up-down direction, and downward direction. In this case, the lock control system can confirm the drag direction from left to right when an angle between -45 degrees and +45 degrees is confirmed. Similarly, when an angle between +45 degrees and +135 degrees is confirmed, the drag direction is shifted upward, when the angle between +135 degrees and -135 degrees is detected, the drag direction is shifted from the right direction to the left direction, If an angle between -45 degrees and -45 degrees is confirmed, the drag direction can be ascertained from upward to downward. In this case, when an angle of +45 is confirmed, the angle is changed from left to right. When an angle of +135 degrees is confirmed, the angle is upward. When an angle of -135 degrees is confirmed, It is possible to confirm the drag direction in the downward direction. Depending on the setting, the direction information may be expanded to eight instead of four.

Assuming that the angle 430 is 50 degrees in the above-described embodiment, the drag direction of the touch-and-drag event corresponding to the straight line 410 can be identified as "upward under ".

FIG. 5 is a block diagram for explaining an internal configuration of a lock control system in an embodiment of the present invention, and FIG. 6 is a flowchart showing a lock control method in an embodiment of the present invention.

The lock control system 500 according to the present embodiment may include a touch sensing device 10, a processor 510, a bus 520, a network interface 530 and a memory 540, as shown in FIG. have. The memory 540 may include an operating system 541 and a lock control routine 542. The processor 510 may include a direction information management unit 511, a drag direction confirmation unit 512, a comparison unit 513, and a lock mode release unit 514. [ In other embodiments, the lock control system 500 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 500 may include other components such as a camera, an acceleration sensor, or a vibration motor.

The memory 540 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 540 may store program codes for the operating system 541 and the lock control routine 542. [ These software components may be loaded from a computer readable recording medium separate from the memory 540 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 540 via the network interface 530 rather than from a computer readable recording medium. For example, the lock control routine 542 may be loaded into the memory 540 based on a program installed by the developers through files provided by the network.

The bus 520 may enable communication and data transfer between components of the lock control system 500. The bus 520 may be configured using a high-speed serial bus, a parallel bus, a Storage Area Network (SAN), and / or any other suitable communication technology. For example, information on the position of the touch recognized by the touch sensing device 10, or information about a touch-and-drag event may be transmitted to the processor 510 via the bus 520 and used by the processor 510, May be transferred to the memory 540 via the memory 520 and stored in the memory 540. Information stored in the memory 540 may also be transferred to the processor 510 via the bus 520.

Network interface 530 may be a computer hardware component for coupling lock control system 500 to a computer network. The network interface 530 may connect the lock control system 500 to the computer network via a wireless or wired connection.

The processor 510 may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input / output operations of the lock control system 500. The instructions may be provided by the memory 540 or the network interface 530 and to the processor 510 via the bus 500. The processor 510 may be configured to execute program codes for the direction information management unit 511, the drag direction confirmation unit 512, the comparison unit 513, and the lock mode release unit 514. [ Such program code may be stored (e. G., A lock control routine 542) in a recording device, such as memory 540. [

At this time, the direction information management unit 511, the drag direction confirmation unit 512, the comparison unit 513, and the lock mode release unit 514 included in the processor 510 perform the steps 610 to 640 of FIG. 6 Lt; / RTI >

In step 610, the direction information management unit 511 may manage the direction information used for releasing the lock mode. For example, the direction information management unit 611 can manage the direction information set by the user or stored in the memory 540.

In step 620, the drag direction confirmation unit 512 can confirm the drag direction of the touch and drag event occurring on the touch screen in the lock mode. For example, in step 620, the drag direction check unit 512 determines whether the straight line connecting the start coordinates and the end coordinates of the touch-and-drag event is based on an angle formed with the reference axis in a virtual coordinate system To confirm the drag direction. For a more specific method, refer to FIG.

In step 630, the comparing unit 513 can compare the determined drag direction with the direction information. For example, when the identified drag direction is "left to right ", the comparing unit 513 can check whether the direction information being managed is" left to right ".

If a plurality of direction information is used, the direction information managing unit 611 can manage the order information of the plurality of direction information and direction information in step 610. [ At this time, in step 630, the comparing unit 513 determines whether the drag direction of each of the plurality of touch-and-drag events continuously generated within a predetermined time interval coincides with the plurality of direction information according to the order information can do.

For example, if the predetermined time interval is 3 seconds, the plurality of direction information is "right to left" and "left to right", and the order information is "left to right" . The drag direction confirmation unit 512 confirms that the drag direction confirmed through the first touch and drag event is "right to left ", and then confirms the drag direction through the second touch and drag event continuously generated within 3 seconds . If the drag direction is not confirmed through the second touch-and-drag event within 3 seconds, the process for confirming the drag direction can be initialized. Of course, the drag direction confirmed through the first touch-and-drag event and the drag direction confirmed through the second touch-and-drag event are right-to-left direction and "left- Right to left direction "next to " right to left direction" must be confirmed so that the drag direction is recognized as matching with the direction information.

In step 640, the lock mode releasing unit 514 can release the lock mode if the determined drag direction and direction information match. When the plurality of direction information is "right to left" and "left to right" and the order information is "left to right" after "right to left" as in the above example, The portion 514 can release the lock mode if the identified drag direction is "right to left" and "left to right ", and are sequentially checked within a predetermined time interval.

In the above embodiments, only the configuration for releasing the lock mode has been described. However, the lock control system 400 may not only release the lock mode but also execute a specific application.

7 is a diagram illustrating an example of a process of executing a specific application at the same time when the lock mode is released in an embodiment of the present invention. In FIG. 7, a first dashed box 710 represents a set of direction information including a plurality of direction information, and a second dashed box 720 represents a plurality of applications. At this time, the direction information is indicated by using arrows for convenience of explanation. If the identified drag directions are "↑", "↑", "↑", "↑" as shown in FIG. 7, this is the direction information set " ↑ ↑ ↑ ↑ "(730). In this case, the lock control system 500 described with reference to Fig. 5 can drive the third application, which is an application corresponding to the direction information set "↑ ↑ ↑ ↑ ↑" 730 simultaneously with 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, the user can set the drag direction to "↑", "↑", "↑", "↑" When four touch and drag events are input, the lock control system 500 releases the lock state of the touch screen and simultaneously drives the third application to display a recent call list through the touch screen.

Of course, the direction information set only for the release of the lock mode may be set, and the other functions of the lock control system 500 and the direction information set 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 the specific direction information set.

For this embodiment, the direction information management unit 511 may manage a plurality of direction information sets including at least one direction information, respectively, and a plurality of functions in association with each other in step 610. 6, in addition to the steps 610 to 640 shown in FIG. 6, executing the function associated with the direction information set used for releasing the lock mode when the lock mode is released (Not shown). This non-illustrated step may be performed by a function execution unit (not shown) further included in the processor 510 of the lock control system 500.

In another embodiment, direction information for unlocking and direction information for driving the application may be used separately.

FIG. 8 is a diagram illustrating another example of a process of executing a specific application at the same time as releasing the lock mode, according to an embodiment of the present invention. 8 shows an example in which direction information for driving an application is separately used separately from the direction information set " < - > - < - & The third dashed line box 820 indicates direction information for driving the application, and the fourth dotted line box 830 indicates a plurality of applications. At this time, each of the directional information of the third dashed box 820 may be associated with each of the applications. If the identified drag directions are "↑", "↑", "←", "←", "↑" as shown in FIG. 8, the previous four drag directions are set as direction information set "↑↑ ← ? "810, and the last one drag direction"? "Can be used for matching with the direction information for driving the application.

At this time, the lock control system 500 can release the lock mode by matching the preceding four drag directions "↑", "↑", "←", "←" with the direction information, and the last one drag direction The third application can be executed by matching the number "3 " with the direction information"? "(840). Although FIG. 8 shows an example in which the direction information for driving the application is composed of one direction information, it may be configured as a direction information set including two or more direction information.

For this embodiment, the direction information management unit 511 can manage direction information sets, each of which includes at least one direction information each used for driving different functions in step 610, in association with the corresponding function have. In step 630, the comparing unit 513 compares the drag direction of some of the drag directions of the plurality of touch-and-drag events with the direction information used for releasing the lock mode, Can be compared with at least one direction information included in the information set. 6, in addition to the steps 610 to 640 shown in FIG. 6, when the lock mode is released, the lock control method described in FIG. 6 confirms the direction information set matched with the remaining drag direction among the direction information sets, And performing a function associated with the identified direction information set (not shown). This non-illustrated step may be performed by a function execution unit (not shown) further included in the processor 510 of the lock control system 500.

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 direction information managing unit 511, the drag direction confirming unit 512, the comparing unit 513, and the lock mode releasing unit 514 are included, .

Although embodiments in which the lock mode is released based on the drag direction have been described in the above embodiments, it can be extended to execute a specific function of the device based on the drag direction. Embodiments for performing a specific function of the apparatus based on the drag direction will be described with reference to FIGS. 9 and 10. FIG.
