In FIG. 4, for example, a cross-section of a touch screen having proximity sensors capable of sensing three proximity depths is illustrated. Of course, proximity sensors that detect less than three or more than four proximity depths are also possible.

Specifically, when the pointer is completely in contact with the touch screen (d ₀ ), it is recognized as a contact touch. If the pointer is located on the touch screen at a distance less than the distance d ₁ , it is recognized as a proximity touch of the first proximity depth. If the pointer is located on the touch screen at a distance of d ₁ or more and less than distance d ₂ , it is recognized as a proximity touch of the second proximity depth. If the pointer is located on the touch screen at a distance of d ₂ or more and less than d ₃ distance, it is recognized as a proximity touch of the third proximity depth. If the pointer is positioned apart from the touch screen by a distance d ₃ or more, it is recognized that the proximity touch is released.

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

5A and 5B are views referred to the description of the proximity touch recognition area where the proximity signal is detected and the haptic area where the tactile effect occurs.

5A shows an object such as an icon or a menu item in a circular form for convenience of explanation. An area of the object displayed on the display unit 151 can be divided into a first area A in the center and a second area B surrounding the first area A as shown in Fig. The first region A and the second region B can be configured to generate tactile effects having different intensities or patterns. For example, when the second region B is touched, a first vibration is output, and when the first region A is touched, a second vibration larger than the first vibration is output.

In the case where the proximity touch recognition area and the haptic area are simultaneously set in the area where the object is displayed, the haptic area where the tactile effect is generated and the proximity touch area where the proximity signal is detected Can be set differently. That is, the haptic area may be set narrower than the proximity touch recognition area, or the haptic area may be set wider than the proximity touch recognition area. For example, in (a) of FIG. 5A, the area including the first area A and the second area B may be a proximity touch recognition area, and the first area A may be set as a haptic area.

(N > 4) as shown in Fig. 5 (a) or (c) as shown in Fig. 5 It is also possible to divide into two areas. Each divided region can be configured to generate a tactile effect with different intensities or patterns. Even when the area in which one object is displayed is divided into three or more areas, the haptic area and the proximity touch recognition area can be set differently according to the use environment.

The size of the proximity touch recognition area may be changed depending on the proximity depth to the display unit 151. [ That is, as shown in (a) of FIG. 5, the corresponding proximity touch recognition area may be gradually reduced to 'C', 'B', and 'A' according to the proximity depth to the display unit 151, Or the contiguous touch recognition area corresponding to the proximity depth to the display unit 151 may be gradually increased. In this case as well, the haptic area can be set to a constant size regardless of the proximity depth to the display unit 151, such as the 'H' area shown in FIG. 5B (b).

 In the case of dividing the area in which the object is displayed for the setting of the haptic area or the proximity touch recognition area, in addition to the concentric segmentation as shown in FIG. 5A, the segmentation in the horizontal direction or the longitudinal direction, the radial segmentation, And various methods such as partitioning can be used.

A configuration in which the above-described projector module is provided in the bar-shaped mobile terminal 100 will be described with reference to FIGS. 6A and 6B. 6A and 6B are perspective views of an example of a mobile terminal according to the present invention.

The main body 101 of the mobile terminal may be coupled with a projector body 105 having the projector module 155 so as to be rotatable.

That is, the projector body 105 can be hinged to the main body 101, and the projection angle of the image can be adjusted when the image is projected using the projector module 155 provided in the projector body 105 And the camera 121 may be disposed on the projector body 105 so that the image projected by the projector module 155 can be photographed.

6A shows a state before the projector body 105 rotatably coupled with the main body 101 is rotated, and FIG. 6B shows a state after the projector body 105 is rotated.

Hereinafter, embodiments related to a control method that can be implemented in the mobile terminal configured as above will be described with reference to the accompanying drawings. It goes without saying that the embodiments described below can be used alone or in combination with each other.

The following embodiments can be more easily implemented when the display unit 151 is configured as a touch screen. However, it should be noted that, even if the display unit 151 is not a touch screen, the following embodiments can be sufficiently implemented by the operation of the user input unit 140. [

Hereinafter, the display screen of the display unit 151 will be referred to as a reference numeral 400.

As shown in (8-1) of FIG. 8, it is assumed that the mobile terminal 100 is in a stand-by state. Accordingly, it is illustrated that the idle screen according to the standby state is displayed on the touch screen 400 of the mobile terminal 100. [ It is needless to say that the mobile terminal 100 is not necessarily in a stand-by state for the implementation of the present embodiment, and other menus may be executed.

Next, as shown in (8-2) of FIG. 8, the mobile terminal 100 receives a telephone call for telephone call connection from the caller terminal through the wireless communication unit 110 (S71). That is, the mobile terminal 100 attempts to make a telephone call connection from the caller terminal. Accordingly, the controller 180 may display a phone call reception notification 510 on the touch screen 400 indicating that the phone call is being received from the caller terminal for a phone call connection attempt.

The telephone call may include certain caller identification information (hereinafter also referred to as "caller information"), such as the caller's telephone number of the calling terminal. In this case, the control unit 180 searches for the other party having the same telephone number as the calling party telephone number among the other parties stored in the telephone directory stored in the memory 160.

(Not shown), the control unit 180 transmits the information of the other party (for example, the name of the other party) together with the caller's telephone number to the touch screen (400). The caller's telephone number may not be displayed and only the information of the other party may be displayed on the touch screen 400. [ In this case, a similar-number display icon, which will be described later, may not be displayed on the touch screen. The similar number display icon will be described later again.

However, if there is no other party having the same telephone number as the sender's telephone number, the control unit 180 determines whether the other party having a telephone number similar to the sender's telephone number .

8 (2), the control unit 180 displays the caller's telephone number 520 on the touch screen 400 and transmits the caller's telephone number 520 to the terminal user Number display icon 420 for selecting to view information of the other party having the similar telephone number (hereinafter, "similar party"). The control unit 180 may display the similar number display icon 420 on the touch screen 400 when the similarity number display icon 420 is selected so that the information of the similar counterpart can be displayed on the touch screen 400 The phrase 415 can be displayed.

If the pseudo-number display icon 420 is not selected and the call icon 430 on the touch screen 400 is selected, for example, the call connection of the phone call is requested, the control unit 400 The information of the similar counterpart can be connected to the caller's phone call without being displayed on the touch screen 400. [

However, if the similar icon display icon 420 is selected (S72), the control unit 180 displays the similar information 530 on the touch screen (not shown) 400) (S73). The controller 180 may display information on some or all of the similar counterparts on the touch screen 400 when the similar counterparts are two or more. The information of the similar counterpart may include at least one of the name and the telephone number of the counterpart counterpart.

When the telephone number of the similar party is displayed in the similar party information 530, the control unit 180 determines which part of the telephone number of the similar party is the same as the caller telephone number, Can be visually displayed.

When the similar information 530 is displayed, the control unit 180 may control the similar icon display icon 420 to disappear. When the pseudo-number display icon 420 disappears, the control unit 180 may control to display another necessary icon 440. [ The other required icons 440 may be displayed in the place where the similarity number display icon 420 disappears. An example of the other necessary icon 440 may be an icon for sending a reject message informing the other party's terminal to reject the telephone call.

On the other hand, if there is no such similar party, the controller 180 may display the caller's telephone number on the touch screen and not display the similar-number display icon 420. [ In this case, although not shown, a guideline informing that there is no such similar party may be displayed on the touch screen.

The similar number display icon 420 for displaying the similar information 530 is displayed on the touch screen 400. However, when the similar number display icon 420 is displayed on the touch screen 400, It is not necessarily displayed on the display device. For example, even if the similar-number display icon 420 is not displayed, the control unit 180 may display the similar information 530 on the touch screen (not shown) through the operation of a keypad of the keypad of the user input unit 130 400 as shown in FIG.

In the above description, the controller 180 first searches the phone book for the similar phone number, displays the similar phone number icon 420 when the similar phone number exists in the phone book, And that the similar number icon 420 is not displayed if it is not in the telephone directory.

However, this embodiment is not limited to this. For example, the control unit 180 may control the display unit 400 to display the similar number display icon 420 on the touch screen 400 regardless of whether the similar party is present in the phone book. In this case, when the similar icon display icon 420 is selected, the control unit 180 searches for the similar phone number in the phone book, and if the similar phone is not in the phone book, And display a guidance message informing that the similar party is absent from the telephone directory. Of course, when the similar terminal is present in the phone book, the controller 180 displays the similar terminal information on the touch screen 400 as described above.

8, various display methods of the similar-number display icon 420 and the similar-like counterpart information according to the above are similar to those of the remaining drawings other than Fig. 8, It is easily understood by those skilled in the art that the present invention can be selectively applied to a display method of counterpart information.

Hereinafter, a criterion that the telephone number of the caller and the telephone number of the other party are considered to be similar to each other will be described with reference to FIG.

In general, the telephone numbers may be divided into two or more groups. For example, in the case of telephone numbers for mobile communication such as "010-1234-5678 ", three groups, i.e., a first group of" 010 ", a second group of "1234 ", and a third group of & do.

As shown in (9-1) of FIG. 9, if the third group number of the calling party telephone number and the third group number of the other party telephone number are the same, it is determined that the calling party telephone number and the other party telephone number are similar . If the third group number of the caller's telephone number and the third group number of the other party's telephone number are completely identical, it may be determined that they are similar to each other, or if more than a predetermined number of digits (for example, three digits) They can be judged to be similar to each other.

As shown in (9-2) of FIG. 9, if the second group number of the calling party telephone number and the second group number of the other party telephone number are the same, it is determined that the calling party telephone number and the other party telephone number are similar . If the second group number of the sender's telephone number and the second group number of the other party's telephone number are completely identical, it may be determined that they are similar to each other, or if more than a predetermined number of digits (for example, three digits) They can be judged to be similar to each other.

As shown in (9-3) of FIG. 9, if the second group number of the calling party telephone number and the third group number of the other party telephone number are the same, it is determined that the calling party telephone number and the other party telephone number are similar . If the second group number of the caller's telephone number and the third group number of the other party's telephone number are completely identical, it may be determined that they are similar to each other, or if more than a predetermined number of digits (for example, three digits) They can be judged to be similar to each other.

As shown in (9-4) in FIG. 9, if the third group number of the calling party telephone number and the second group number of the opposite party telephone number are the same, it is determined that the calling party telephone number and the counterpart telephone number are similar . If the third group number of the caller's telephone number and the second group number of the counterpart telephone number are completely identical, it may be determined that they are similar to each other, or if more than a predetermined number of digits (for example, three digits) They can be judged to be similar to each other.

In the above description, the information of the similar counterpart is displayed while the mobile terminal 100 attempts to establish a telephone conversation from the caller terminal.
