The broadcast receiving module 111 receives broadcast signals and broadcast related information from an external broadcast management server through a broadcast channel. Here, the broadcast-related information means information related to a broadcast channel, a broadcast program, or a broadcast service provider. The broadcast-related information can also be provided through a mobile communication network. In this case, the broadcast-related information may be received by the mobile communication module 112. The broadcast signal and the broadcast related information received through the broadcast receiving module 111 may be stored in the memory 160.

The mobile communication module 112 transmits and receives radio signals to at least one of a base station, an external terminal, and a server on a mobile communication network. Such wireless signals may include various types of data depending on a voice call signal, a video call signal, a text message, or a multimedia message transmission / reception.

The wireless Internet module 113 is a module for wireless Internet access, and may be embedded in the mobile terminal 100 or externally. Wireless Internet technologies may include Wireless LAN (Wi-Fi), Wireless Broadband (Wibro), World Interoperability for Microwave Access (Wimax), High Speed Downlink Packet Access (HSDPA), and the like.

The short range communication module 114 refers to a module for short range communication. As a short range communication technology, Bluetooth, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, and the like can be used.

The position information module 115 is a module for acquiring the position of the mobile terminal 100, and a representative example thereof is a Global Position System (GPS) module.

1, an A / V (Audio / Video) input unit 120 is for inputting an audio signal and a video signal, and may include a camera 121, a microphone 122, and the like. The camera 121 processes image frames such as still images and moving images obtained by the image sensor in the video communication mode or the photographing mode. The image frame processed by the camera 121 can be displayed on the display unit 151. [ The image frame may be stored in the memory 160 or transmitted to the outside through the wireless communication unit 110. [ More than two cameras 121 may be provided depending on the use environment.

The microphone 122 processes the sound signal input from the outside in the communication mode, the recording mode, the voice selection mode, and the like as electrical voice data. The voice data processed by the microphone 122 in the communication mode can be converted into a form that can be transmitted to the mobile communication base station through the mobile communication module 112 and output. The microphone 122 may be implemented with various noise reduction algorithms for eliminating noise generated when an external sound signal is input.

The touch sensor may be configured to detect a touch pressure as well as a touched position and area.

When the touch sensor and the display unit 151 have a mutual layer structure, the display unit 151 can be used as an input device in addition to the output device. The display unit 151 may be referred to as a 'touch screen'.

If there is a touch input via the touch screen, signals corresponding thereto are sent to a touch controller (not shown). The touch controller processes the signals transmitted from the touch sensor, and then transmits data corresponding to the processed signals to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched.

In the case where the touch screen is electrostatic, it can be configured to detect the proximity of the sensing object by a change of the electric field along the proximity of the sensing target. Such a touch screen may be classified as proximity sensor 141. [

The proximity sensor 141 refers to a sensor that detects the presence or absence of an object to be sensed without mechanical contact using an electromagnetic force or infrared rays. The proximity sensor 141 has a longer life than the contact type sensor and its utilization is also high. Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor.

Hereinafter, for convenience of explanation, a proximity action is referred to as " proximity touch " while an object to be sensed does not touch the touch screen, and an action of touching the sensing object on the touch screen is called & touch ".

The proximity sensor 141 detects the presence or absence of 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, The information corresponding to the presence / absence of proximity touch and the proximity touch pattern can be output to the touch screen.

In addition, the controller 180 may set the number of screen switching according to the degree to which the touch on the second icon is applied.

When the screen displayed on the display unit 151 is repeatedly switched a set number of times, the controller 180 may make the second icon disappear. In addition, the controller 180 may change the shape or color of the first icon to be the same as before the change.

Although the drawing shows that the screen displayed on the display unit 151 is changed differently according to the type of touch input, what is differently controlled by the controller 180 is not limited thereto. For example, when a region is set on the screen displayed on the display unit 151, the controller 180 may control the set region differently according to which of the first and second touch inputs to the object is. .

In detail, when a plurality of objects that can receive a touch input are included in the set area, the controller 180 may detect a touch input for one object. In this case, when the touch input for one object is the first touch input, the controller 180 may select only the object for which the touch input is detected. On the other hand, when the touch input for one object is the second touch input, the controller 180 may select all of the plurality of objects included in the set area.

As described above, the mobile terminal 100 and the control method thereof according to an embodiment of the present invention may control the screen differently according to the type of the touch input to the icon. For example, the number of switching of the screen displayed on the display unit 151 may vary according to the type of touch input for the icon corresponding to the screen switching function. Accordingly, since the number of icons displayed on the screen can be reduced, the user can more fully appreciate the screen. Consequently, the convenience of the user can be improved.
