As an example, the touch input means consists of a virtual key, soft key, or visual key displayed on a touch screen through software processing, or a part other than the touch screen. It can be made of a touch key (touch key) disposed on. On the other hand, the virtual key or visual key can be displayed on the touch screen while having various forms, for example, graphic (graphic), text (text), icon (icon), video (video) or these can be made of a combination of

Meanwhile, the sensing unit 140 senses at least one of information within the terminal, surrounding environment information surrounding the terminal, and user information, and generates a sensing signal corresponding thereto. Based on these sensing signals, the control unit 180 may control driving or operation of the terminal 100 or may perform data processing, functions, or operations related to applications installed in the terminal 100 . 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 existing nearby without mechanical contact by using the force of an electromagnetic field or infrared rays. The proximity sensor 141 may be disposed in an inner area of the terminal surrounded by the touch screen described above or in the vicinity of the touch screen.

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 capacitance type proximity sensor, a magnetic type proximity sensor, an infrared proximity sensor, and the like. If the touch screen is a capacitive type, the proximity sensor 141 may be configured to detect the proximity of a conductive object as a change in electric field according to the proximity of the 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 description, an action of approaching a touch screen without contacting an object to recognize that the object is located on the touch screen is referred to as a "proximity touch", and the touch An act of actually touching an object on a screen is called a "contact touch". The location at which an object is proximity-touched on the touch screen means a location at which the object corresponds vertically to the touch screen when the object is proximity-touched. The proximity sensor 141 may detect a proximity touch and a proximity touch pattern (eg, proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch movement state, etc.) there is. Meanwhile, as described above, the controller 180 processes data (or information) corresponding to the proximity touch operation and proximity touch pattern detected through the proximity sensor 141, and furthermore, visual information corresponding to the processed data. It can be output on the touch screen. Furthermore, the controller 180 may control the terminal 100 to process different operations or data (or information) depending on whether a touch to the same point on the touch screen is a proximity touch or a contact touch.

The touch sensor detects a touch (or touch input) applied to the touch screen (or the display unit 151) using at least one of various touch methods such as a resistive film method, a capacitive method, an infrared method, an ultrasonic method, and a magnetic field method. detect

As an example, the touch sensor may be configured to convert a change in pressure applied to a specific part of the touch screen or capacitance generated in a specific part into an electrical input signal. The touch sensor may be configured to detect a location, area, pressure upon touch, capacitance upon touch, and the like, at which a touch object that applies a touch to the touch screen is touched on the touch sensor. Here, the touch object is an object that applies a touch to the touch sensor, and may be, for example, a finger, a touch pen, a stylus pen, or a pointer.

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 corresponding data to the controller 180. Thus, the controller 180 can know which area of the display unit 151 has been touched. Here, the touch controller may be a component separate from the controller 180 or may be the controller 180 itself.

Meanwhile, the controller 180 may perform different controls or the same control according to the type of the touch object that touches the touch screen (or a touch key provided other than the touch screen). Whether to perform different controls or the same control according to the type of touch object may be determined according to an operating state of the terminal 100 or an application program being executed.

On the other hand, the touch sensor and proximity sensor described above are independently or combined, short (or tap) touch, long touch, multi-touch, drag touch on the touch screen ), flick touch, pinch-in touch, pinch-out touch, swipe touch, hovering touch, etc. Touch can be sensed.

The ultrasonic sensor may recognize location information of a sensing object by using ultrasonic waves. Meanwhile, the controller 180 may calculate the location of the wave generating source through information detected by the optical sensor and the plurality of ultrasonic sensors. The position of the wave generating source can be calculated using the property that light is much faster than ultrasonic waves, that is, the time for light to reach the optical sensor is much faster than the time for ultrasonic waves to reach the ultrasonic sensor. More specifically, the location of the wave generating source may be calculated by using light as a reference signal and a time difference between the arrival time of ultrasonic waves.

Meanwhile, looking at the configuration of the input unit 120, the camera 121 includes at least one of a camera sensor (eg, CCD, CMOS, etc.), a photo sensor (or 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 target for a 3D stereoscopic image. A photo sensor may be stacked on a display device, and the photo sensor is configured to scan a motion of a sensing target close to the touch screen. More specifically, the photo sensor scans the content placed on the photo sensor by mounting photo diodes and transistors (TRs) in rows/columns and using electrical signals that change according to the amount of light applied to the photo diodes. That is, the photo sensor calculates the coordinates of the sensing object according to the change in light, and through this, the location information of the sensing object can be obtained.

The display unit 151 displays (outputs) information processed by the terminal 100 . For example, the display unit 151 may display execution screen information of an application program driven in the terminal 100 or UI (User Interface) and GUI (Graphic User Interface) information according to such execution screen information.

Also, the display unit 151 may be configured as a 3D display unit that displays a 3D image.

A 3D display method such as a stereoscopic method (glasses method), an auto stereoscopic method (non-glasses method), or a projection method (holographic method) may be applied to the 3D display unit.

In general, a 3D stereoscopic image is composed of a left image (image for the left eye) and a right image (image for the right eye). According to the method of combining the left and right images into a 3D stereoscopic image, top-down method in which the left and right images are arranged up and down in one frame, left and right images in one frame L-to-R (left-to-right, side by side) method for arranging left and right images, checker board method for arranging pieces of left and right images in tile form, and left and right images in units of columns Alternatively, it is divided into an interlaced method that alternately arranges rows, and a time-sequential, frame-by-frame method that alternately displays a left image and a right image by time.

Also, the 3D thumbnail image may be generated as a single image by generating left and right image thumbnails from the left and right images of the original image frame, respectively, and combining them. In general, a thumbnail refers to a reduced image or a reduced still image. The generated left and right image thumbnails are displayed with a left and right distance difference on the screen by a depth corresponding to the parallax between the left and right images, thereby representing a three-dimensional sense of space.

A left image and a right image necessary for implementing a 3D stereoscopic image may be displayed on a stereoscopic display unit by a stereoscopic processing unit. The stereoscopic processing unit receives 3D images (images at a reference point and images at an extended point of view) and sets left and right images therefrom, or receives 2D images and converts them into left and right images.

The audio output unit 152 may output audio data received from the wireless communication unit 110 or stored in the memory 170 in a call signal reception, a call mode or a recording mode, a voice recognition mode, a broadcast reception mode, and the like. The sound output unit 152 also outputs sound signals related to functions performed by the terminal 100 (eg, call signal reception sound, message reception sound, etc.). The sound output unit 152 may include a receiver, a speaker, a buzzer, and the like.

The haptic module 153 generates various tactile effects that a user can feel. A representative example of the tactile effect generated by the haptic module 153 may be vibration. The strength and pattern of the vibration generated by the haptic module 153 may be controlled by a user's selection or a setting of a controller. For example, the haptic module 153 may synthesize and output different vibrations or sequentially output them.

In addition to vibration, the haptic module 153 responds to stimuli such as an array of pins that move vertically with respect to the contact skin surface, air blowing force or suction force through a nozzle or suction port, rubbing against the skin surface, electrode contact, and electrostatic force.
