In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Hereinafter, for convenience of explanation, the act of allowing the pointer to be recognized without being in contact with the touch screen so that the pointer is located on the touch screen is referred to as a "proximity touch", and the touch The act of actually touching the pointer on the screen is called "contact touch." The position where the proximity touch is performed by the pointer on the touch screen refers to a position where the pointer is perpendicular to the touch screen when the pointer is in proximity proximity.

The proximity sensor detects a proximity touch and a proximity touch pattern (for example, 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). Information corresponding to the sensed proximity touch operation and proximity touch pattern may be output on the touch screen.

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

The alarm unit 153 outputs a signal for notifying occurrence of an event of the mobile terminal 100. Examples of events occurring in the mobile terminal include call signal reception, message reception, key signal input, and touch input. The alarm unit 153 may output a signal for notifying occurrence of an event in a form other than a video signal or an 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 151 and 152 may be classified as part of the alarm unit 153.

Hereinafter, the operation of the display unit 151 and the touch pad (not shown) will be described with reference to FIGS. 2A and 2B.

2A and 2B are front views of a portable terminal for explaining an operation state of the portable terminal according to the present invention.

Various types of time information can be displayed on the display unit 151. [ These pieces of information can be displayed in the form of letters, numbers, symbols, graphics, or icons.

At least one of the letters, numbers, symbols, graphics, or icons may be displayed in a predetermined arrangement for inputting such information, thereby being implemented as a keypad. Such a keypad may be referred to as a so-called " virtual keypad ".

2A illustrates receiving a touch applied to the virtual keypad through the front of the terminal body.

The display unit 151 may operate in an entire area or may be operated in a divided manner. In the latter case, the plurality of areas can be configured to operate in association with each other.

For example, an output window 151a and an input window 151b are displayed on the upper and lower portions of the display unit 151, respectively. The output window 151a and the input window 151b are areas allocated for outputting or inputting information, respectively. In the input window 151b, a virtual keypad 151c is displayed in which a number for inputting a telephone number or the like is displayed. When the virtual keypad 151c is touched, numbers and the like corresponding to the touched virtual keypad are displayed on the output window 151a. When the first operation unit 131 is operated, call connection to the telephone number displayed on the output window 151a is attempted.

2B illustrates receiving a touch applied to the virtual keypad through the rear of the terminal body. If FIG. 2A is a portrait in which the terminal body is arranged vertically, FIG. 3B illustrates a landscape in which the terminal body is arranged horizontally. The display unit 151 may be configured to convert the output screen according to the arrangement direction of the terminal body.

2B illustrates that the text input mode is activated in the mobile terminal. The display unit 151 displays an output window 151a 'and an input window 151b'. A plurality of virtual keypads 151c 'displaying at least one of letters, symbols, and numbers may be arranged in the input window 151b'. The virtual keypads 151c 'may be arranged in the form of a QWERTY key.

When the virtual keypads 151c 'are touched through a touch pad (not shown), letters, numbers, symbols, etc. corresponding to the touched virtual keypads are displayed on the output window 151a'. As described above, the touch input through the touch pad has an advantage of preventing the virtual keypad 151c 'from being covered by the finger when touched, as compared with the touch input through the display unit 151. When the display unit 151 and the touch pad are transparent, the fingers located on the rear of the terminal body can be visually checked, and thus more accurate touch input is possible.

In addition to the input method disclosed in the above embodiments, the display unit 151 or the touch pad may be configured to receive a touch input by scrolling. The user may move a cursor or a pointer located on an object displayed on the display unit 151, for example, an icon, by scrolling the display unit 151 or the touch pad. In addition, when the finger is moved on the display unit 151 or the touch pad, a path along which the finger moves may be visually displayed on the display unit 151. This may be useful for editing an image displayed on the display unit 151.

In response to the display unit 151 (touch screen) and the touch pad being touched together within a predetermined time range, one function of the terminal may be executed. In the case of being touched together, there may be a case where the user clamps the terminal body using the thumb and index finger. For example, the function may include activation or deactivation of the display unit 151 or the touch pad.

The proximity sensor 141 described with reference to FIG. 1 will be described in more detail with reference to FIG. 3.

3 is a conceptual diagram illustrating a proximity depth of a proximity sensor.

As shown in FIG. 3, when a pointer such as a user's finger or a pen approaches the touch screen, the proximity sensor 141 disposed in or near the touch screen detects this and outputs a proximity signal.

The proximity sensor 141 may be configured to output different proximity signals according to a distance between the proximity touched pointer and the touch screen (hereinafter, referred to as “proximity depth”).

In FIG. 3, for example, a cross section of a touch screen on which three proximity sensors capable of sensing three proximity depths is disposed 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 touch touch. When the pointer is positioned below the distance d ₁ on the touch screen, the pointer is recognized as a proximity touch of a first proximity depth. When the pointer is spaced apart from the distance d ₁ or more and less than d ₂ on the touch screen, the pointer is recognized as a proximity touch of a second proximity depth. When the pointer is spaced apart from the distance d ₂ or more and less than d ₃ on the touch screen, the pointer is recognized as a proximity touch of a third proximity depth. When the pointer is positioned at a distance of more than d ₃ from the touch screen, the proximity touch is recognized as released.

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

It is assumed that the mobile terminal referred to herein may include at least one of the components shown in FIG. 1. In addition, the mobile terminal 100 may perform not only a 2D display but also a 3D display using the display unit 151.
