A representative example of the transparent display is TOLED (Transparant OLED). The rear structure of the display unit 151 may also be configured as a light transmissive structure. With this structure, the user can see the object located behind the terminal body through the area occupied by the display unit 151 of the terminal body.

According to an implementation form of the mobile terminal 100, two or more display units 151 may exist. For example, a plurality of display units may be spaced apart or integrally disposed on one surface of the mobile terminal 100, or may be disposed on different surfaces, respectively.

In addition, the display unit 151 may be configured as a stereoscopic display unit 152 for displaying a stereoscopic image.

Here, the stereoscopic image represents a three-dimensional stereoscopic image, and the three-dimensional stereoscopic image represents a gradual depth and reality in which an object is placed on a monitor or a screen. This is a video that lets you feel the same as space. 3D stereoscopic images are implemented using binocular disparity. Binocular parallax means the parallax made by the position of two eyes that are separated. When the two eyes see different two-dimensional images and the images are transferred to the brain through the retina and are fused, the depth and reality of the stereoscopic image can be felt. .

The stereoscopic display unit 152 may be a three-dimensional display method such as stereoscopic (glasses), auto stereoscopic (glasses), projection (holographic). Stereoscopic methods commonly used in home television receivers include Wheatstone stereoscope.

Examples of the auto stereoscopic method include a parallax barrier method, a lenticular method, an integrated imaging method, a switchable lens, and the like. Projection methods include reflective holographic methods and transmissive holographic methods.

Generally, a 3D stereoscopic image is composed of a left image (left eye image) and a right image (right eye image). A top-down method in which the left and right images are arranged up and down in one frame according to the way in which the left and right images are merged into three-dimensional stereoscopic images. L-to-R (left-to-right, side by side) method to be arranged as a checker board method to arrange the pieces of the left and right images in the form of tiles, a column unit of the left and right images Or an interlaced method of alternately arranging rows, and a time sequential (frame by frame) method of alternately displaying left and right images by time.

In addition, the 3D thumbnail image may generate a left image thumbnail and a right image thumbnail from the left image and the right image of the original image frame, respectively, and combine them to generate one 3D thumbnail image. In general, a thumbnail refers to a reduced image or a reduced still image. The left image thumbnail and the right image thumbnail generated as described above are displayed with a left and right distance difference on the screen by a depth corresponding to the parallax of the left image and the right image, thereby representing a three-dimensional space.

The left image and the right image necessary for implementing the 3D stereoscopic image may be displayed on the stereoscopic display 152 by a stereoscopic processor (not shown). The stereo processing unit receives a 3D image and extracts a left image and a right image therefrom, or receives a 2D image and converts the image into a left image and a right image.

On the other hand, when the display unit 151 and a sensor for detecting a touch operation (hereinafter, referred to as a “touch sensor”) form a mutual layer structure (hereinafter referred to as a “touch screen”), the display unit 151 outputs the same. In addition to the device can also be used as an input device. The touch sensor may have, for example, a form of a touch film, a touch sheet, a touch pad, or the like.

The touch sensor may be configured to convert a change in pressure applied to a specific portion of the display unit 151 or capacitance generated in a specific portion of the display unit 151 into an electrical input signal. The touch sensor may be configured to detect not only the position and area where the touch object is touched on the touch sensor but also the pressure at the touch. Here, the touch object is an object applying a touch to the touch sensor and may be, for example, a finger, a touch pen or a stylus pen, a pointer, or the like.

If 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 the corresponding data to the controller 180. As a result, the controller 180 can know which area of the display unit 151 is touched.

Referring to FIG. 1, a proximity sensor 141 may be disposed in an inner region of a mobile terminal surrounded by the touch screen or near the touch screen. The proximity sensor 141 may be provided as an example of the sensing unit 140. 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. The proximity sensor 141 has a longer life and higher utilization than a contact sensor.

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. When the touch screen is capacitive, the touch screen is configured to detect the proximity of the pointer by a change in an electric field according to the proximity of a conductive object (hereinafter, referred to as a pointer). In this case, the touch screen (touch sensor) may be classified as a proximity sensor.

Hereinafter, for convenience of explanation, an 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 at which the proximity touch is performed by the pointer on the touch screen means a position where the pointer is perpendicular to the touch screen when the pointer is in proximity proximity.

The proximity sensor 141 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.

When the stereoscopic display unit 152 and the touch sensor form a mutual layer structure (hereinafter, referred to as a “stereoscopic touch screen”), or when the stereoscopic display unit 152 and the 3D sensor detecting a touch operation are combined with each other. The stereoscopic display unit 152 may also be used as a three-dimensional input device.

As an example of the 3D sensor, the sensing unit 140 may include a proximity sensor 141, a stereoscopic touch sensing unit 142, an ultrasonic sensing unit 143, and a camera sensing unit 144.

The proximity sensor 141 measures the distance between a sensing object (for example, a user's finger or a stylus pen) and a detection surface to which a touch is applied without mechanical contact by using an electromagnetic force or infrared rays. The terminal recognizes which part of the stereoscopic image is touched using this distance. In particular, when the touch screen is capacitive, the proximity of the sensing object is detected by a change in electric field according to the proximity of the sensing object, and the touch screen is configured to recognize a three-dimensional touch using the proximity.

The stereoscopic touch sensing unit 142 is configured to detect the strength or duration of the touch applied to the touch screen. For example, the three-dimensional touch sensing unit 142 detects a pressure to apply a touch, and if the pressure is strong, recognizes it as a touch on an object located farther from the touch screen toward the inside of the terminal.

The ultrasonic sensing unit 143 uses ultrasonic waves to recognize position information of the sensing object.

The ultrasonic sensing unit 143 may be formed of, for example, an optical sensor and a plurality of ultrasonic sensors. The optical sensor is configured to detect light, and the ultrasonic sensor is configured to detect ultrasonic waves. Because light is much faster than ultrasonic waves, the time that light reaches the optical sensor is much faster than the time that ultrasonic waves reach the ultrasonic sensor. Therefore, the position of the wave generation source can be calculated using the time difference from the time when the ultrasonic wave reaches the light as the reference signal.

The camera sensing unit 144 includes at least one of a camera 121, a photo sensor, and a laser sensor.

For example, the camera 121 and the laser sensor are combined with each other to sense a touch of a sensing object with respect to a 3D stereoscopic image. When the distance information detected by the laser sensor is added to the 2D image photographed by the camera, 3D information may be obtained.

As another example, a photo sensor may be stacked on the display element. The photo sensor is configured to scan the movement of the sensing object in proximity to the touch screen. More specifically, the photo sensor mounts a photo diode and a transistor (TR) in a row / column and scans contents mounted on the photo sensor by using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor calculates coordinates of the sensing object according to the amount of change of light, and thereby obtains the position information of the sensing object.

The sound output module 153 may output 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. The sound output module 153 may also output a sound signal related to a function (for example, a call signal reception sound or a message reception sound) performed in the mobile terminal 100. The sound output module 153 may include a receiver, a speaker, a buzzer, and the like.

The alarm unit 154 outputs a signal for notifying occurrence of an event of the mobile terminal 100. Examples of events generated in the mobile terminal 100 include call signal reception, message reception, key signal input, and touch input. The alarm unit 154 may output a signal for notifying occurrence of an event by using 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 sound output module 153, and thus the display unit 151 and the sound output module 153 may be classified as part of the alarm unit 154. .

The haptic module 155 generates various tactile effects that a user can feel. A representative example of the tactile effect generated by the haptic module 155 may be vibration. The intensity and pattern of vibration generated by the haptic module 155 may be controlled by the user's selection or the setting of the controller. For example, the haptic module 155 may output different synthesized vibrations or sequentially output them.

In addition to the vibration, the haptic module 155 may be configured to provide a pin array that vertically moves with respect to the contact skin surface, a jetting force or suction force of air through the jetting or suction port, grazing to the skin surface, contact of the electrode, electrostatic force, and the like. Various tactile effects can be generated, such as effects by the endothermic and the reproduction of a sense of cold using the elements capable of endotherm or heat generation.

The haptic module 155 may not only transmit the haptic effect through direct contact, but also may implement the user to feel the haptic effect through the muscle sense such as a finger or an arm. Two or more haptic modules 155 may be provided according to configuration aspects of the mobile terminal 100.

The memory 160 may store a program for the operation of the controller 180 and may temporarily store input / output data (for example, a phone book, a message, a still image, a video, etc.). The memory 160 may store data relating to various patterns of vibration and sound output when a touch input on the touch screen is performed.

The memory 160 may be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory), RAM random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), programmable read-only memory (PROM), magnetic memory, magnetic It may include a storage medium of at least one type of a disk and an optical disk. The mobile terminal 100 may be operated in connection with a web storage that performs a storage function of the memory 160 on the Internet.

The interface unit 170 serves as a path with all external devices connected to the mobile terminal 100. The interface unit 170 receives data from an external device, receives power, transfers the power to each component inside the mobile terminal 100, or transmits data inside the mobile terminal 100 to an external device. For example, a port for connecting a device equipped with a wired / wireless headset port, an external charger port, a wired / wireless data port, a memory card port, and an identification module. The audio input / output (I / O) port, video input / output (I / O) port, earphone port, and the like may be included in the interface unit 170.

A device equipped with an identification module (hereinafter referred to as an 'identification device') may be manufactured in the form of a smart card. Therefore, the identification device may be connected to the terminal 100 through the interface unit 170.

In addition, when the mobile terminal 100 is connected to an external cradle, the interface unit 170 serves as a passage through which power from the cradle is supplied to the mobile terminal 100, or inputted from the cradle by a user. Various command signals may be a passage through which the mobile terminal 100 is transmitted. Various command signals or power input from the cradle may operate as signals for recognizing that the mobile terminal 100 is correctly mounted on the cradle.
