For example, an external display unit (not shown) and an internal display unit (not shown) may be simultaneously provided in the mobile terminal 100.

The touch screen may be configured to detect a touch input pressure as well as a touch input position and area.

The proximity sensor 141 may be disposed inside or near the touch screen. 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. Therefore, the proximity sensor 141 has a considerably longer life than the contact sensor, and its utilization is also considerably higher.

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.

To explain an example of the operation principle of the high frequency oscillation type proximity sensor, the oscillation amplitude of the oscillation circuit is attenuated or stopped when the sensing object approaches the sensor sensing surface while oscillating the high frequency wave of the wave in the oscillation circuit. This change is converted into an electrical signal to detect the presence or absence of a sensing object. Therefore, even if a non-metallic material comes between the high frequency oscillation proximity sensor and the sensing object, the proximity switch can detect the sensing object to be detected without interference of the object.

Even if the proximity sensor 141 is not firmly mounted, when the touch screen is capacitive, the proximity sensor 141 may be configured to detect the proximity of the pointer by a change in an electric field according to the proximity of the pointer.

Therefore, when the pointer is located in close proximity to the touch screen although it is not actually touched, the position of the pointer and the distance between the pointer and the touch screen may be detected. Hereinafter, for convenience of explanation, the act of allowing the pointer to be recognized on the touch screen so that the pointer is located on the touch screen is referred to as a "proximity touch", and the pointer on the touch screen is referred to as "proximity touch". The act of actually contacting will be referred to as "contact touch". In addition, the position of the proximity touch with 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 touch.

The proximity sensor 141 detects proximity touch and proximity touch patterns (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.). According to the detected proximity touch operation and the proximity touch pattern, corresponding information may be output on the touch screen.

The sound output module 152 outputs audio data received from the wireless communication unit 110 or stored in the memory 160 in a call signal reception, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, and the like. In addition, the sound output module 152 outputs a sound signal related to a function (eg, a call signal reception sound, a message reception sound, etc.) performed by the mobile terminal 100. The sound output module 152 may include 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 the event include call signal reception, message reception, key signal input, and touch input. The alarm unit 153 outputs a signal for notifying occurrence of an event in a form other than an audio signal or a video signal. For example, the signal may be output in the form of vibration. When a call signal is received or a message is received, the alarm unit 153 may output a vibration to inform this. Alternatively, when a key signal is input, vibration may be output as feedback to the key signal input. The user can recognize the occurrence of the event through the vibration output as described above. Of course, a signal for notification of event occurrence may be output through the display unit 151 or the sound output module 152.
