Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence or absence of an object approaching a predetermined detection surface or an object present in the vicinity without using a mechanical contact by using an electromagnetic force or infrared rays. In the proximity sensor 141, the proximity sensor 141 may be disposed near the touch screen or an inner region of the mobile terminal covered by the touch screen.

Examples of the proximity sensor 141 include a transmission photoelectric sensor, a direct reflection photoelectric sensor, a mirror reflection photoelectric sensor, a high frequency oscillation proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the object with the change of the electric field according to the proximity of the conductive object. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the action of allowing the object to be recognized without being in contact with the touch screen so that the object is located on the touch screen is called a "proximity touch", and the object on the touch screen Is actually referred to as "contact touch". The position where the object is in close proximity touch on the touch screen refers to a position where the object is perpendicular to the touch screen when the object is in close proximity touch. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, and a proximity touch movement state). Meanwhile, as described above, the controller 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern detected by the proximity sensor 141, and further, touch screen visual information corresponding to the processed data.

The touch sensor may be configured to detect a position, an area, a pressure at the touch, a capacitance at the touch, and the like, when the touch object applying the touch on the touch screen is touched on the touch sensor. Here, the touch object is an object applying a touch to the touch sensor and may be, for example, a finger, a touch pen, a stylus pen, a pointer, or the like.

As such, when 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 then transmits the corresponding data to the controller 180. As a result, the controller 180 can know which area of the display unit 151 is touched. The touch controller may be a separate component from the controller 180 or may be the controller 180 itself.

The controller 180 may perform different control or perform the same control according to the type of the touch object, which touches the touch screen (or a touch key provided in addition to the touch screen). Whether to perform different control or the same control according to the type of touch object may be determined according to the operation state of the mobile terminal 100 or an application program being executed.

The ultrasonic sensor may recognize location information of a sensing object using ultrasonic waves. On the other hand, the controller 180 can calculate the position of the wave generation source through the information detected from the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the property that light is much faster than ultrasonic waves, that is, the time that the light reaches the optical sensor is much faster than the time when the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generation source may be calculated using a time difference from the time when the ultrasonic wave reaches the light as the reference signal.

On the other hand, the camera 121 in the configuration of the input unit 120 includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or an image sensor) and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to detect a touch of a sensing object with respect to a 3D stereoscopic image. The photo sensor may be stacked on the display element, which is configured to scan the movement of the sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column to scan contents loaded on the photo sensor by using an electrical signal that changes according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of change of light, and through this, position information of the sensing object can be obtained.

The intensity and pattern of vibration generated by the haptic module 153 may be controlled by the user's selection or the setting of the controller. For example, the haptic module 153 may synthesize different vibrations and output them or output them sequentially.

In addition to the vibration, the haptic module 153 is a pin array that vertically moves with respect to the contact skin surface, the jetting force or suction force of the air through the injection or inlet, the grazing to the skin surface, the contact of the electrode, the electrostatic force, and the like.

For example, the second location information may include a right direction with respect to the first coordinate and a distance from the first coordinate. The direction of the touch coordinates and the distance of the touch coordinates may be provided with reference of directions and distances by various sensing means such as an acceleration sensor, a magnetic sensor, a gravity sensor, a gyroscope sensor, a touch sensor, and the like.

In addition, when the second touch coordinates are within a preset distance from the first coordinates, the second touch coordinates may be determined to be the same coordinates as the first touch coordinates. In this case, the first controller 181 may determine that the first touch input and the second touch input are received at the same position on the display unit 151. However, when the second touch coordinates exceed a preset distance from the first coordinates, the second touch coordinates may be determined to be different from the first touch coordinates. In this case, the first controller 181 may determine that the first touch input and the second touch input are received at different positions on the display unit 151.

Thereafter, information about the n-th touch, which is the N-th touch made to the display unit 151 that is in an inactive state, may also be stored in the first storage unit 171 in the same manner as described above.

That is, the user may sequentially input touches to be set among the displayed coordinate areas 155. For example, as shown in FIG. 5 (c), the user has a first area 155-1 with a first rank, a first area 155-1 with a second rank, and a second area with a third rank ( 155-2, the fourth region 155-4 may be sequentially touched with the fourth rank.

In this case, the first controller 181 may determine touch coordinates for each of the plurality of touch inputs (S440). If it is determined that all of the plurality of touch inputs are within the coordinate area 155 (S450_Y), the first controller 181 may store touch coordinates corresponding to each of the plurality of touch inputs in the buffer. In addition, even if the plurality of touch inputs are within the coordinate region 155 and the last touch input is for selecting a confirmation button formed in addition to the coordinate region 155, the first controller 181 may not be able to access the coordinate region 155. Touch coordinates corresponding to each of the plurality of touch inputs may be stored in a buffer. Thereafter, the second controller 182 may enter a second step by giving a command to end the first step of setting touch coordinates (S480). This will be described in detail with reference to FIGS. 6 to 7.

However, if it is determined that at least one of the plurality of touch inputs is not within the coordinate area 155 (S450_N), the second controller 182 may command to end the touch coordinate setting (S460). For example, when the cancel button shown in FIG. 5C is selected, the second controller 182 may control the screen as shown in FIG. 5D to be displayed, and all steps of the touch coordinate setting may be performed. It can be terminated or cancelled.

In addition, even if it is determined that all of the plurality of touch inputs are within the coordinate area 155, when it is determined that the predetermined input method is violated, a screen as shown in FIG. 5E may be displayed. In this case, a screen for guiding a touch input method may be displayed.

That is, the second controller 182 may control the display unit 151 to display a quadrant for re-input of the plurality of touch coordinates (S620). That is, a screen as shown in FIG. 7A may be displayed.

Thereafter, the display unit 151 may receive a touch input for the displayed touch coordinates (S630). That is, the user may sequentially input the same touch as the touch input input in the first step. For example, as shown in FIG. 7B, the user has a first area 155-1 in a first rank, a first area 155-1 in a second rank, and a second area in a third rank (as shown in FIG. 7B). 155-2, the fourth region 155-4 may be sequentially touched with the fourth rank.

If it is determined that the touch coordinates corresponding to each of the plurality of touch inputs are the same as the touch coordinates stored in the buffer (S650_Y), the first controller 181 stores the touch coordinates corresponding to each of the plurality of touch inputs in the first storage unit 171. ) Can be stored. Thereafter, the second controller 182 may issue a command to end the second step of setting touch coordinates (S670). As a result, all of the touch coordinate settings may be finished. In this case, a screen as shown in FIG. 7C is displayed, and the user may be informed that the touch coordinate setting is finished.

However, if it is determined that the touch coordinates corresponding to each of the plurality of touch inputs are not the same as the touch coordinates stored in the buffer (S650_N), the second controller 182 may issue a command to restart the check of the touch coordinates (S610). . That is, if it is determined that the touch input made in the first step and the touch input made in the second step are different, the second controller 182 may display a screen for retrying the touch input in the second step. As shown in Fig. 5 (d).

4 to 7 illustrate a method of setting touch coordinates or knock codes. Hereinafter, a detailed method of activating or maintaining the deactivation state of the display unit 151 in the deactivation state will be described in a state where setting of the knock code is completed.

FIG. 8 is an example of a timing diagram for activating the display unit 151 according to input touch coordinates in the mobile terminal 100 according to an embodiment of the present invention, and FIG. 9 illustrates a touch input. Various examples of drawings for.

First, the display unit 151 may receive a touch input in an inactive state (S810). That is, the user may touch input the display unit 151 in a deactivated state. In this case, the first controller 181 may control the display unit 151 to form the plurality of virtual regions 156, and the virtual region 156 is different from the coordinate region 155 described with reference to FIG. 5 or 7. Alternatively, it may mean a virtual touch area that is not displayed on the display unit 151.

Thereafter, the first controller 181 may determine a plurality of touch coordinates corresponding to each of the input touches (S820).

For example, as illustrated in FIG. 9A, the user may touch an arbitrary point on the display unit 151 in an inactive state with a first rank. In this case, an area of a preset range may correspond to the first area 155-1 from the touch point of the first rank, and the touch of the first rank may be determined to be a touch on the first area 155-1. have. Thereafter, the second touch may be performed at the same point as the first rank, and the touch of the second rank may be determined as a touch on the first region 155-1. Thereafter, the third rank touch is made in the right direction with respect to the second rank touch. In this case, an area of a preset range may correspond to the second area 155-2 from the touch point of the third rank, and the touch of the third rank may be determined to be a touch on the second area 155-2. have. Thereafter, a fourth rank of touch is made in the downward direction with respect to the third rank of touch. In this case, an area of a preset range may correspond to the fourth area 155-4 from the touch points of the fourth rank, and the touch of the fourth rank may be determined to be a touch on the fourth area 155-4. have. Accordingly, the first controller 181 may determine touch coordinates of each of the plurality of touches input to the virtual area 156.

Meanwhile, the size, position, etc. of the virtual area 156 may be adjusted according to the input touch. 9B and 9E, the distance between the touch point of the second rank and the touch point of the third rank and the touch point of the third rank and the touch point of the fourth rank are equal to each other. In addition, the touch point of the third rank is right with respect to the touch point of the second rank, and the touch point of the fourth rank is lower with respect to the touch point of the third rank. Accordingly, the first controller 181 may determine touch coordinates of each of the plurality of touches input to the virtual area 156.

Thereafter, the first controller 181 may determine whether the touch coordinates of each of the plurality of touch inputs are the same as the touch coordinates stored in the first storage unit 171 (S830). If it is determined that the touch coordinates corresponding to each of the plurality of touch inputs are the same as the touch coordinates stored in the first storage unit 171 (S830_Y), the first controller 181 transmits a matching signal to the second controller 182. It may be (S860). Thereafter, the second controller 182 may make a command to activate the display unit 151 which is in an inactive state (S870). As a result, the display unit 151 may be activated.

However, if it is determined that the touch coordinates corresponding to each of the plurality of touch inputs are not the same as the touch coordinates stored in the first storage unit 171 (S830_N), the first controller 181 may transmit a mismatch signal to the second controller 182. It can be transmitted to (S840). Thereafter, the second controller 182 may issue a command to maintain the deactivation state of the display unit 151 (S850).

FIG. 10 is a diagram for describing a method in which touch coordinates are stored in the first storage unit 171 according to an exemplary embodiment.

As shown in FIG. 10A, the first storage unit 171 may be divided into a plurality of pages, and each page includes a header area 172, a page area 173, and a code area 174. do. When a user makes a touch input to set touch coordinates for the first time, the first controller 181 may encode touch information corresponding to the input touch coordinates and record the touch information in the code area 174 of the first page. Accordingly, the first controller 181 may determine whether touch information of the first page among the plurality of pages and the touch information input through the display unit 151 are the same. In this case, since touch information corresponding to one touch coordinate is recorded in the first page, 1 may be recorded in the header area 172 of the first page.

Thereafter, the user may set new touch coordinates to update the touch information. In this case, as illustrated in FIG. 10B, the first controller 181 may encode touch information corresponding to newly input touch coordinates and record the touch information in the code area 174 of the second page. Accordingly, the first controller 181 may determine whether the touch information of the second page most recently stored among the plurality of pages and the touch information input through the display unit 151 are the same. In this case, since touch information corresponding to one touch coordinate is recorded on the second page, 1 may be recorded in the header area 172 of the second page.

According to the above-described method, updated touch information may be stored for each page, and after 1 is recorded in the header area 172 for the Nth page, the user may set new touch coordinates to update the touch information. . In this case, as shown in FIG. 10 (d), the first controller 181 may encode touch information corresponding to newly input touch coordinates and record the touch information in the code area 174 of the first page. In this case, since touch information corresponding to two touch coordinates is recorded on the first page, 2 may be recorded in the header area 172 of the first page. Accordingly, the first controller 181 may determine whether the updated touch information of the first page stored among the plurality of pages and the touch information input through the display unit 151 are the same.

As such, the first storage unit 171 implemented as an embedded flash memory may be divided into a plurality of pages, and the first control unit 181 may store touch information for one of the plurality of pages. Therefore, it is possible to substantially solve the problem of capacity limitation in storing touch information.

11 is various examples of a diagram illustrating another input method for activating the display unit 151 of the mobile terminal 100 according to an embodiment of the present invention, and FIG. It is an example of a timing diagram relating to activation. Hereinafter, descriptions of portions overlapping with the above description will be omitted.

In the above description, a plurality of touches made on the display unit 151 have been described. However, the present invention is not limited thereto, and the touches may be applied to the drag made on the display unit 151. That is, the above description may also be applied to user signature recognition as shown in FIG. 11 (a) or pattern recognition as shown in FIG. 11 (b).

First, the display unit 151 may receive a drag input in an inactive state (S1210). That is, the user may drag input to the display unit 151 in a deactivated state, and the first controller 181 may determine drag coordinates corresponding to the input drag (S1220).

Thereafter, the first controller 181 may determine whether the drag coordinates for the drag input and the drag coordinates stored in the first storage unit 171 are the same (S1230). In this case, of course, the preset drag coordinates should be stored in the first storage unit 171.

Therefore, when it is determined that the drag coordinates corresponding to the drag input are the same as the drag coordinates stored in the first storage unit 171 (S1230_Y), the first controller 181 may transmit a matching signal to the second controller 182 ( S1260). Thereafter, the second controller 182 may issue a command to activate the display unit 151 which is in an inactive state (S1270). As a result, the display unit 151 may be activated.

However, if it is determined that the drag coordinates corresponding to the drag input are not the same as the drag coordinates stored in the first storage unit 171 (S1230_N), the first controller 181 may transmit a mismatch signal to the second controller 182. There is (S1240). Thereafter, the second controller 182 may issue a command to maintain the deactivation state of the display unit 151 (S1250).

The present invention described above can be embodied as computer readable codes on a medium in which a program is recorded. The computer readable medium includes all kinds of recording devices that store data that can be read by a computer system. Examples of computer-readable media include hard disk drives (HDDs), solid state disks (SSDs), silicon disk drives (SDDs), ROM, RAM, CD-ROMs, magnetic tapes, floppy disks, and optical data storage devices. And also implemented in the form of a carrier wave (eg, transmission over the Internet). The computer may also include a controller 180 of the terminal. The above detailed description, therefore, is not to be taken in a limiting sense in all respects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
