(Hereinafter, referred to as a 'touch screen') in which a display unit 151 and a sensor for sensing a touch operation (hereinafter, referred to as 'touch sensor') form a mutual layer structure, It can also be used as an input device. The touch sensor may have the form of, for example, a touch film, a touch sheet, a touch pad, or the like.

The touch sensor may be configured to convert a change in a pressure applied to a specific portion of the display unit 151 or a capacitance generated in a specific portion of the display unit 151 into an electrical input signal. The touch sensor can be configured to detect not only the position and area to be touched but also the pressure at the time of touch.

If there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like.

Referring to FIG. 1, a proximity sensor 141 may be disposed in an inner region of the mobile terminal or in the vicinity of the touch screen, which is surrounded by the touch screen. The proximity sensor refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or a nearby object without mechanical contact using the force of an electromagnetic field or infrared rays.

[ The audio output module 152 may include a receiver, a speaker, a buzzer, and the like.

The alarm unit 153 outputs a signal for notifying the occurrence of an event of the mobile terminal 100. Examples of events that occur in the mobile terminal include call signal reception, message reception, key signal input, touch input, and the like. The alarm unit 153 may output a signal for notifying the occurrence of an event in a form other than the video signal or the audio signal, for example, vibration. The video signal or the audio signal may be output through the display unit 151 or the audio output module 152 so that they may be classified as a part of the alarm unit 153.

The haptic module 154 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 154 is vibration. The intensity and pattern of the vibration generated by the hit module 154 can be controlled. For example, different vibrations may be synthesized and output or sequentially output.

The haptic module 154 can be implemented not only to transmit the tactile effect through the direct contact but also to allow the user to feel the tactile effect through the muscular sensation of the finger or arm. At least two haptic modules 154 may be provided according to the configuration of the mobile terminal 100.

The memory 160 may store a program for the operation of the controller 180 and temporarily store input / output data (e.g., a phone book, a message, a still image, a moving picture, etc.). The memory 160 may store data on vibration and sound of various patterns outputted when a touch is input on the touch screen.

The memory 160 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory), a RAM (Random Access Memory), SRAM (Static Random Access Memory), ROM (Read Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM A disk, and / or an optical disk. The mobile terminal 100 may operate in association with a web storage that performs a storage function of the memory 160 on the Internet.

The interface unit 170 serves as a path for communication with all external devices connected to the mobile terminal 100. The interface unit 170 receives data from an external device or supplies power to each component in the mobile terminal 100 or transmits data to the external device. For example, a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, a port for connecting a device having an identification module, an audio I / O port, A video input / output (I / O) port, an earphone port, and the like may be included in the interface unit 170.

2 is a conceptual diagram for explaining the proximity distance of the proximity sensor.

As shown in FIG. 2, when a pointer such as a user's finger, pen, or the like approaches the touch screen, the proximity sensor 141 disposed in or near the touch screen senses the proximity sensor and outputs a proximity signal.

The proximity sensor 141 may be configured to output different proximity signals according to a vertical distance (hereinafter referred to as "proximity distance") between the proximity-touched pointer and the touch screen.

In FIG. 2, for example, a cross section of a touch screen having proximity sensors capable of sensing three proximity distances is illustrated. Of course, proximity sensors that detect less than three or more than four proximity distances are also possible.

Specifically, when the pointer is completely in contact with the touch screen (d0), it is recognized as a contact touch. If the pointer is located on the touch screen at a distance less than the distance d1, it is recognized as a proximity touch of the first proximity distance. If the pointer is located on the touch screen at a distance d1 or less and less than the distance d2, the pointer is recognized as a proximity touch of the second proximity distance. When the pointer is located on the touch screen at a distance d2 or more and less than the distance d3, it is recognized as a proximity touch of the third proximity distance. If the pointer is located at a distance d3 or more on the touch screen, it is recognized that the proximity touch is released.

Accordingly, the control unit 180 can recognize the proximity touch as various input signals according to the proximity distance and the proximity position of the pointer, and perform various operation control according to the various input signals.

Hereinafter, a method for releasing a terminal lock (touch screen lock) in a terminal configured as above will be described in detail with reference to the accompanying drawings.

In the embodiments of the present invention, the terminal locking function is used to prevent malfunction due to a user's unintended touch while the user does not use the touch screen in the terminal having the touch screen or to prevent the user from using the terminal will be. The terminal adopting the terminal locking function sets a touch screen to hold the touch screen even if a touch is inputted on the touch screen when the touch screen is not used, Unlock to activate the touch screen.

The touch screen may include a movement pattern (e.g., a movement pattern) formed when the user moves a pointer such as a finger or the like to move in a state in which the pointer is moved in proximity or touch position, proximity distance, proximity or touch holding time, Path), and so on.

The control unit 180 performs lock setting or unlocking of the touch screen according to user input or predetermined setting information. For example, when the automatic locking function is set, the control unit 180 locks the touch screen if there is no input on the touch screen for a predetermined time. When the controller 180 receives the touch screen unlock command in the touch screen locked state, the control unit 180 requests the unlock password input. When the user inputs the unlocking password in response to the request, the controller 180 checks whether the inputted unlocking password matches the predetermined unlocking password. If the inputted unlocking password matches the preset unlocking password, the controller 180 unlocks the touch screen. If the entered unlocking password does not match the preset unlocking password, .

The unlock password includes a two-dimensional pattern or a three-dimensional pattern using a touch time generated by touching or proximity of a pointer sensed on a touch screen. The two-dimensional pattern using the touch time is formed by combining a movement pattern formed by the pointer while the touch is maintained on the touch screen and a holding time at a predetermined node on the movement pattern. The three-dimensional pattern is formed by a combination of a proximity distance and a proximity position of the pointer, a proximity holding time, a movement pattern (path) formed by moving the pointer in the proximity state, and the like.

The memory 160 stores an unlock password (unlock pattern) set (registered) when the touch screen lock function is set. That is, the two-dimensional pattern or the three-dimensional pattern using the touch time set by the user in advance as the unlock password is stored in the memory 160.

3 is a flowchart illustrating an unlocking method of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 3, the controller 180 sets a two-dimensional pattern using a three-dimensional pattern or touch time as an unlock code for performing unlocking of the touch screen (S101). For example, the control unit 180 executes the unlock pattern setting function in response to user input. The unlock pattern setting function registers the unlock pattern for user authentication when the touch screen is unlocked. In addition, the controller 180 can set the lock function of the touch screen in response to a user input. In addition to the lock of the screen, the controller 180 can set a function of the function (e.g., a camera, a web browser, , Message dispatch, etc.) or by information (phonebook, content archive, incoming and outgoing history, message archive, memo, etc.).

After setting the unlock password, the controller 180 activates the touch screen when the unlock request is received in the touch screen locked state, and detects the input of the unlock pattern on the touch screen (S102, S103). For example, when the user inputs a hold key located at one side of the terminal, the controller 180 recognizes the request as an unlock request of the touch screen. Then, the control unit 180 displays a pattern input window for inputting the unlock pattern on the touch screen. If the unlock pattern is input to the pattern input window, the controller 180 recognizes the unlock pattern.

The controller 180 checks whether the detected unlock pattern matches the set unlock pattern (S104). That is, the controller 180 determines whether the pattern input in the current pattern input window (pattern input area) is the same as the pattern input in step S101.

If it is determined that the detected unlock pattern matches the unlock pattern, the controller 180 cancels the lock of the touch screen and activates the touch screen (S105).

On the other hand, if it is determined that the detected unlock pattern does not match the unlock pattern, the controller 180 maintains the locked state of the touch screen (S106). At this time, the controller 180 may output a warning or warning message indicating that the detected unlock pattern does not match the set unlock pattern.

4A and 4B illustrate an unlock pattern registration screen of a mobile terminal according to an embodiment of the present invention.

First, when the user selects the unlock pattern setting menu, the controller 180 executes the selected unlock pattern setting menu and displays an execution screen as shown in FIG. 4A on the touch screen. The controller 180 arranges and displays a plurality of nodes for inputting an unlock pattern in a pattern input area. The number of nodes displayed in the pattern input area may be set by a user. For example, when the user selects a 4x4 node array, the controller 180 arranges and displays 16 nodes in the pattern input area in 4x4. The user inputs a pattern to connect (pass) at least a predetermined number of nodes among the displayed plurality of nodes. And, it is possible to input the holding time of the touch at the node on the pattern differently.

In other words, if a touch of a pointer is detected in the pattern input area, the controller 180 controls the touch point of the pointer, the touch end point, the movement path between the touch start point and the touch end point through the sensing unit 140, Time, and the like, and recognizes a pattern input in the pattern input area.

Herein, the controller 180 measures the holding time when the holding of a touch is detected at a predetermined node, changes the color of the corresponding node according to the holding time, or displays an arrow on the edge of the node, . In addition, the controller 180 may visually provide the user with the fun using the flash effect according to the holding time.

When the recognition of the pattern input in the pattern input area is completed, the controller 180 displays the recognized pattern on the display unit 151 as shown in FIG. 4B. As shown in FIG. 4B, the controller 180 visually displays the node and the moving direction of the pointer, the holding time at the node, and the like. Accordingly, when the user confirms the pattern information displayed on the display unit and selects the 'continue' icon, the control unit 180 requests the inputting of the inputted pattern again, and if the pattern is input again, Check. If it is determined that the re-input pattern is the same as the previously input pattern, the controller 180 sets the pattern as an unlock pattern. On the other hand, if the re-input pattern does not match the previously input pattern, the controller 180 outputs a warning and / or warning message indicating that the re-entered pattern does not match the previously input pattern.

In addition, the controller 180 activates the touch screen locking function when the setting of the unlock pattern is completed. For example, the controller 180 locks the touch screen if the touch input does not occur for a predetermined time on the touch screen. Alternatively, when the lock button of the user input unit 130 is input, the control unit 180 switches the touch screen to the locked state.

5A and 5B illustrate three-dimensional pattern inputs of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 5A, the controller 180 enters a setting mode for setting an unlock pattern for unlocking the touch screen according to a user's input. Upon entering the setting mode, the controller 180 displays the pattern setting cube on the display screen. The pattern setting cubes are arranged in the (x, y, z) axis when they are constituted by a plurality of hexagonal blocks.

If the user places the pointer at a position perpendicular to the block located at (x, y) = (2, 1) and holds the pointer near the touch screen at the third proximity distance for a predetermined time, the controller 180 (x, y, z) = (2, 1, 1), and changes the color of the corresponding block. Accordingly, the user can recognize the selection of the block as the color changes.

When the user inputs a predetermined pattern through the proximity touch input, the controller 180 combines the proximity distance, the proximity position, the proximity movement pattern (path) of the pointer, the holding time at the predetermined proximity position (block) Lt; / RTI >

When the pattern recognition is completed, the control unit 180 displays the recognized pattern on the display screen as shown in FIG. 5B. If the user desires to input a new pattern again after confirming the pattern displayed on the display screen, if the 'retry' icon is selected, the controller 180 displays a pattern as shown in FIG. 5A Display the setting cube.

On the other hand, if the user desires to set the unlock pattern by confirming the pattern displayed on the display screen, when the user selects the 'continue' icon, the controller 180 displays the unlock pattern A pattern setting cube is displayed on the touch screen so that the input pattern can be inputted. The control unit 180 recognizes a re-input pattern input through the proximity touch on the pattern setting cube, confirms whether the re-input pattern coincides with the previously input pattern, If the input pattern matches the input pattern, the controller 180 sets the unlock pattern in the input pattern.

If the re-input pattern does not match the previously input pattern, the controller 180 outputs a warning or warning message.

6 illustrates an example of a mobile terminal unlocking associated with an embodiment of the present invention.

First, when the unlock button of the user input unit 130 is operated by the user in the locked state of the touch screen, the controller 180 detects the operation of the unlock button and displays an unlock pattern input screen on the touch screen ). As shown in FIG. 6 (a), the controller 180 arranges and displays pattern nodes in the pattern input area of the touch screen.

The controller 180 recognizes the input pattern when a pattern is input in the pattern input area as shown in FIG. 6 (b). That is, the controller 180 senses a touch start position (point), a touch end position (point), a touch movement pattern, a holding time at a predetermined node, and recognizes the input pattern based on the sensed information.

Also, the control unit 180 checks whether the recognized pattern matches the preset unlock pattern. If it is determined that the recognized pattern matches the preset unlock pattern, the controller 180 unlocks the touch screen (c). In other words, the controller 180 cancels the lock state so that the terminal can be used when the unlock pattern input by the user matches the predetermined unlock pattern.

On the other hand, if the recognized pattern does not match the preset unlock pattern, the control unit 1800 outputs a warning sound through the sound output module 152 or displays a warning message on the display screen. And the warning message may be simultaneously output together.

In addition to the unlock pattern disclosed in the above embodiments, registration in various three-dimensional patterns is possible. For example, as shown in FIG. 7, it is also possible to rotate the predetermined surface of the cube so as to form a specific shape such as a cross on one side of the cube as an unlock pattern.

Further, according to an embodiment of the present invention, the above-described method can be implemented as computer-readable code on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer-readable medium include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like, and also implemented in the form of a carrier wave (for example, transmission over the Internet) . In addition, the computer may include a control unit 180 of the terminal.

The above-described terminal may be configured such that the configuration and method of the embodiments described above are not limitedly applied, but the embodiments may be configured such that all or some of the embodiments are selectively combined so that various modifications may be made. have.
