In addition, when the detected touch time exceeds the preset time, the controller 440 may determine that the entire display area of the display unit 450 is not equal to the effective area based on the calculated coordinate value. It can be set as an effective area.

In addition, the controller 440 calculates a first coordinate value corresponding to the position information included in the first signal detected by the sensor unit 420. In this case, the received first signal is a signal detected by the sensor unit 420 generated by a first touch input (or change in illuminance value). In addition, the controller 440 calculates a second coordinate value corresponding to the position information included in the second signal received by the display unit 450. In this case, the received second signal is a signal generated by a second touch input to an arbitrary position on the display unit 450.

Hereinafter, a method of controlling a mobile terminal according to the present invention will be described in detail with reference to FIGS. 3 to 11.

4 is a flowchart illustrating a control method of a mobile terminal according to a first embodiment of the present invention.

First, the display unit 450 receives (or detects) a first signal generated by a first touch input (first user input or first user touch input) for an arbitrary position of the display unit 450. do. In this case, the display unit 450 may be a touch screen.

For example, as illustrated in FIG. 5A or 5B, the display unit 450 may be generated by a first user touch input to the first position 501 or the second position 502 of the display unit 450. The first control signal can be received.

As another example, as illustrated in FIG. 5C, the display unit 450 may receive a first control signal generated by a first user touch input to a third position 503 of the display unit 450. There is (S110).

Thereafter, the controller 440 calculates a coordinate value corresponding to an arbitrary position included in the received first signal. In addition, the controller 440 detects a touch time (or a duration of a touch) for the arbitrary position (S120).

Thereafter, the controller 440 determines whether the calculated coordinate value is located within a predetermined area (including one or more coordinate values).

For example, as illustrated in FIG. 5A or 5B, the controller 440 may include a coordinate value calculated in correspondence with the first position 501 or the second position 502 in the preset region ( It is determined whether it is located within (511).

As another example, as illustrated in FIG. 5C, the controller 440 determines whether a coordinate value calculated corresponding to the third position 503 is located in the preset area 511 (S130). .

As a result of the determination, when the calculated coordinate value is located within the preset area, the controller 440 may convert the entire display area of the display unit 450 into an effective area and an invalid area based on the calculated coordinate value. Set separately. In this case, the effective area may mean an area capable of detecting a touch input by a user's touch input, and the invalid area may mean an area that does not sense a touch input by a user's touch input. Here, the invalid area may be set to various types of areas such as a square, a rhombus, a circle, an ellipse, and the like within a predetermined distance based on the coordinate value. The non-effective area may include a predetermined area of one or more surfaces adjacent to the coordinate value among all display areas (up / down / left / right / surfaces) of the display unit 450.

As an example, when the calculated coordinate value is located within the predetermined area, as illustrated in FIG. 5D, the controller 440 may calculate the calculated coordinates among the entire display area 521 of the display unit 450. An area including a value may be set as an invalid area 522, and a remaining area of the entire display area 521 except for the invalid area 522 may be set as an effective area 523, respectively.

In addition, when the calculated coordinate value is located within the predetermined area, the controller 440 may calculate the calculated coordinates in the entire display area (up / down / left / right surfaces) of the display unit 450. The remaining areas except for some areas of one or more surfaces adjacent to the value may be reset to the display area of the display unit 450.

For example, when the calculated coordinate value is located within the predetermined area, as illustrated in FIG. 5E, the controller 440 may display the entire display area 541 (up / down / up / down) of the display unit 450. A portion of one surface (for example, a right side) including the calculated coordinate value among the left and right surfaces is set as an invalid region 542, and the invalid region 542 is included in the entire display region 541. The remaining areas except for the above can be set as the effective areas 543.

In addition, the controller 440 may perform an arbitrary function corresponding to the received first signal when the calculated coordinate value is located within the preset area (eg, the preset invalid area). I never do that. That is, when the calculated coordinate value is located within the predetermined area, the controller 440 may have the received first function even if there is any function corresponding to the calculated coordinate value based on the received first signal. The signal is recognized as a touch by the user's grip and does not perform any function corresponding to the first signal.

In addition, when the calculated coordinate value is located within the preset area, the controller 440 checks whether the touch time for the detected arbitrary position exceeds a preset time, As a result of the checking, when the detected touch time exceeds the preset time, the entire display area of the display unit 450 may be set as an effective area and an invalid area based on the calculated coordinate value. .

In addition, the controller 440 may determine a preset operation or function corresponding to the calculated coordinate value based on the calculated coordinate value when the detected touch time does not exceed the preset time. Do this. For example, the controller 440 may include a coordinate value calculated corresponding to the second position 502 illustrated in FIG. 5B in the preset region 511, and the detected time may be the preset time ( For example, when not exceeding 3 seconds, a predetermined function corresponding to the second position 502 may be performed (S140).

Thereafter, the controller 440 displays the content (or content) displayed on the display unit 450 based on the set valid area and the invalid area.

For example, as illustrated in FIG. 5D, the controller 440 displays the invalid area 522 of the display unit 450 in a predetermined color, transparently, or in a three-dimensional format. The display may be displayed on a preset pattern screen (for example, hatched, lattice, etc.) (S150).

Subsequently, when receiving the second signal generated by the second user touch input to the invalid area based on the set valid area and the invalid area, the control unit 440 responds to the received second signal. It does not perform the corresponding additional operation (or function).

In addition, when receiving a third signal generated by a third user touch input to the valid area based on the set valid area and the invalid area, the controller 440 corresponds to the received third signal. A predetermined operation (or function) is performed (S160).

In addition, when the determination result (the determination result in step S130), the calculated coordinate value is not located in the predetermined area, the controller 440 performs a predetermined operation or function corresponding to the calculated coordinate value. To perform.

For example, the controller 440 may not have a coordinate value calculated in correspondence with the third position 503 illustrated in FIG. 5C without being located in the preset region 511. If located in the, it is possible to perform a predetermined function corresponding to the coordinate value calculated based on the detected third position (503) (S170).

As such, the mobile terminal 400 automatically recognizes the touch input as a touch caused by a user's grip or malfunction when a part of the display portion is touched by a user's grip or malfunction in the display unit having a touch screen. can do.

In addition, when the mobile terminal 400 recognizes any touch input as a touch caused by a user's grip or malfunction, the mobile terminal 400 sets a specific area corresponding to the arbitrary touch input as an invalid area, and displays it. The remaining areas except the invalid area may be set as valid areas, respectively.

6 is a flowchart illustrating a control method of a mobile terminal according to a second embodiment of the present invention.

First, the sensor unit 420 may include a first touch input (or change in illuminance value according to the first touch / proximity input) of at least one sensor module among the plurality of sensor modules included in the sensor unit 420. Detects the signal and generates a first signal corresponding to the detected first touch input (or change in illuminance value according to the first touch / proximity input) and outputs the first signal to the controller 440. In this case, the sensor unit 420 may be configured by arranging a plurality of sensor modules in a bezel area adjacent to the display unit 450. In this case, the plurality of sensor modules may include a touch sensor, a proximity sensor, an illumination sensor, and the like. In addition, among the display areas of the display unit 450, the remaining touch areas other than the preset touch areas according to an application program may also be included in the bezel area.

For example, as illustrated in FIG. 7A, the sensor unit 420 may include a first touch through at least one sensor module among a plurality of sensor modules 712 (including a touch sensor) configured in the bezel area 711. The input 713 is detected and a first signal corresponding to the detected first touch input 713 is generated. In this case, the first touch input 713 may include one or more touch inputs by one or more sensor modules of the plurality of sensor modules 712, respectively.

As another example, the sensor unit 420 may include a first touch according to the proximity of an object through at least one sensor module among the plurality of sensor modules 712 (including a proximity sensor) configured in the bezel area 711. An input (or first proximity touch) 713 is detected and a first signal corresponding to the detected first touch input 713 is generated.

As another example, the sensor unit 420 may include any object (for example, a finger) through at least one sensor module of the plurality of sensor modules 712 (including an illuminance sensor) configured in the bezel area 711. In operation S210, a change in the illuminance value according to the proximity or the touch is detected and a first signal corresponding to the position of the sensor module in which the change in the illuminance value is detected is generated.

Thereafter, the display unit 450 receives a second signal generated by a second touch input for an arbitrary position of the display unit 450. In this case, the display unit 450 may be a touch screen.

For example, as illustrated in FIG. 7A, the display unit 450 may receive a second control signal generated by a second user touch input with respect to the second position 716 of the display unit 450. There is (S220).

Thereafter, the controller 440 calculates coordinate values corresponding to arbitrary positions included in the first signal output from the sensor unit 420 and the second signal received from the display unit 450, respectively.

That is, the control unit 440 calculates a first coordinate value corresponding to an arbitrary position included in the first signal output from the sensor unit 420, and controls the second signal received from the display unit 450. A second coordinate value corresponding to another arbitrary position included is calculated. In this case, when the first signal or the second signal includes information on a plurality of positions, the controller 440 may calculate respective coordinate values corresponding to the plurality of positions (S230).

Thereafter, the controller 440 determines whether the calculated distance between the first coordinate value and the second coordinate value is smaller than a preset threshold value (S240).

As a result of the determination, when the calculated distance between the first coordinate value and the second coordinate value is smaller than the predetermined threshold value, the controller 440 controls the received second signal to be touched by a user's grip. And does not perform any function corresponding to the second signal.

In addition, when the calculated distance between the first coordinate value and the second coordinate value is smaller than a preset threshold, the controller 440 recognizes the received second signal as a touch by a user's grip. Among the entire display areas (up / down / left / right surfaces) of the display unit 450, a predetermined area of at least one surface closest to the calculated first coordinate value and / or the second coordinate value is set as an invalid area. For example, the set invalid area may be set to an area in which a touch input by a user's touch input is not detected.

For example, the controller 440 may include the calculated first coordinate value and / or shown in FIG. 7A when the distance between the calculated first coordinate value and the second coordinate value is smaller than a preset threshold. Since the second coordinate values are adjacent to the right side (right side) and the bottom side (lower side) of the display unit 450, as shown in FIG. 7B, certain areas of the right side and the bottom side of the display unit 450 are ineffective. It is set to 721 and 722, and the additional operation or function corresponding to the additional signal according to the user's touch input is not performed on the set invalid area 721 and 722 (S250).

Also, as a result of the determination, when the calculated distance between the first coordinate value and the second coordinate value is greater than or equal to the preset threshold value, the controller 440 calculates the value based on the received second signal. A preset operation or function corresponding to the second coordinate value is performed (S260).

8 is a flowchart illustrating a control method of a mobile terminal according to a third embodiment of the present invention.

First, the controller 440 may receive a first signal generated by a first touch input (first user input or first user touch input) of the bezel area adjacent to the display unit 450 and / or the display unit 450. On the basis of this, the entire display area of the display unit 450 is set as a first valid area and a first invalid area. In addition, the controller 440 displays the set first valid region and the first invalid region on the display unit 450. In this case, the first invalid area may be displayed in a predetermined color, transparently, in a three-dimensional format, or displayed in a preset pattern screen (eg, hatched, grid, etc.). Can be. Here, the effective area may mean an area that can sense a touch input by a user's touch input, and the invalid area may mean an area that does not sense a touch input by a user's touch input.

For example, as illustrated in FIG. 9A, the controller 440 may include a first position generated by a first touch input 902 on an arbitrary position of the display unit 450 or the bezel area 901. The first valid region 911 and the first invalid region 912 set based on the signal are displayed on the display unit 450.

In addition, in FIG. 9A, only a portion of the surface on the display unit 450 is displayed as an invalid region. However, in addition to the portion, the surface may be ineffective for one or more of the top, bottom, left, and right surfaces of the display unit 450. It can also be set. That is, when the user rotates the terminal from the horizontal direction to the vertical direction or the vertical direction to the horizontal direction by setting one or more borders or a predetermined area of all the borders on the display unit 450 to the invalid area, the user habit ( For example, it is invalid for a surface (for example, a lower end) in which an incorrect touch input for a temporary grip is expected in consideration of a user's habit of first gripping the lower end capable of supporting the weight of the terminal. A temporary weight for the region may be given (S310).

Subsequently, when the movement of the mobile terminal 400 is detected through the motion recognition sensor included in the sensor unit 420, the controller 440 may be configured based on the detected movement of the mobile terminal 400. Among the first valid region and the first invalid region, weights are assigned to the first invalid region to reset the first invalid region and the first valid region. In this case, the controller 440 may assign a predetermined weight to the first invalid area based on the detected movement of the mobile terminal 400 to determine the size (or range) of the first invalid area. In operation S320, the size of the first effective region may be decreased.

Thereafter, the controller 440 displays the reset second invalid area and the second valid area on the display unit 450.

For example, as illustrated in FIG. 9A, the controller 440 is in a state in which the first valid region 911 and the first invalid region 912 are displayed on the display unit 450. In FIG. 9B, when the mobile terminal 400 detects a movement such that the mobile terminal 400 rotates clockwise or counterclockwise by the motion recognition sensor included in the sensor unit 420, The first valid area 911 and the first invalid area 912 are reset to set the second valid area 921 and the second invalid area 922, and the reset second valid area 921 is reset. ) And the second invalid area 922 may be displayed on the display unit 450 (S330).

10 is a flowchart illustrating a control method of a mobile terminal according to a fourth embodiment of the present invention.

First, the display unit 450 sequentially receives a plurality of signals generated by a plurality of touch inputs (or a plurality of user touch inputs) for different positions of the display unit 450. In this case, the display unit 450 may be a touch screen.

For example, the display unit 450 may include a first signal, a second signal, and a first signal generated by a first touch input, a second touch input, and a third touch input at different positions of the display unit 450. Each of the three signals is received (S410).

Thereafter, the controller 440 determines whether the received plurality of signals is a touch by a user's grip, based on the received plurality of signals.

That is, the controller 440 determines whether the information about any location corresponding to the plurality of signals received in the order corresponds to the order of predefined location information, and thus the received signals are determined by the user. It is determined whether it is a touch by a grip.

For example, as illustrated in FIG. 11, the controller 440 may include the predefined location information as “A region 1101 → B region 1102 → C region 1103”, “A region ( 1101 → C region 1103 → B region 1102 ”,“ C region 1103 → A region 1101 → B region 1102 ”, and“ C region 1103 → B region 1102 → A region 1101 includes position information corresponding to each touch order in the order of " A ", to the received plurality of signals, that is, the first signal, the second signal, and the third signal received in the order. It is determined whether corresponding location information is included in the predefined location information (S420).

As a result of the determination, when the plurality of received signals is a touch by a grip of the user, the controller 440 stops the touch operation and does not perform any function corresponding to the received plurality of signals.

For example, as illustrated in FIG. 11, the received first signal, the second signal, and the third signal may be located in the B region 1102, the C region 1103, and the A region 1101. Or the B region 1102, the A region 1101, and the position with respect to the C region 1103, respectively, that is, the B region 1102 → C region 1103 → A region 1101 (or When a touch is detected in the order of area B 1102 → area A 1101-> area C 1103, and the order of the detected location information is not included in the order of the predefined location information, The control unit 440 determines that the touch input by the position information detected in the order is a touch input by the user's grip, and stops the additional touch operation, and any operation corresponding to the received signals or Does not perform a function (S430).

In addition, as a result of the determination, when the received signals are not a touch by the user's grip, the controller 440 may correspond to the touch inputs (or a plurality of signals received in the order) that are input in the order. Perform a predefined action or function.

For example, as illustrated in FIG. 11, the received first signal, the second signal, and the third signal are respectively sensed in the order of A area 1101 → B area 1102 → C area 1103. When the detected order of the position information is included in the order of the predefined position information, the controller 440 performs a predefined function corresponding to the detected position information in the order ( S440).

In addition, the control unit 440 determines that an invalid touch action is performed when a plurality of signals sequentially received are consecutively performed a predetermined number of times, and performs an operation or function corresponding to the plurality of received signals. It may not be performed. That is, when the order pattern of the touch input is continuously performed for a predetermined number or more, it may be determined as an invalid touch action and may not perform any operation or function corresponding to the plurality of received signals.

As described above, the display area of the display unit 450 is divided into a plurality of parts, and the display area is based on an order of signals generated by a touch input to the plurality of divided display areas (ie, an order according to a user's touch input). By determining whether the order of signals is a touch input according to a predefined order, it may be determined whether the touch is a user's grip.

As described above, if a touchable screen area is set among the display areas of the display unit 450 for each application program, and a touch input is received in the order corresponding to the preset display areas, the predetermined function or operation is performed. Can be configured to do so.
