The broadcast channel may include a satellite channel and a terrestrial channel. The broadcast managing entity may indicate a server which generates and transmits a broadcast signal and/or broadcast associated information or a server which receives a pre-generated broadcast signal and/or broadcast associated information and sends them to the mobile terminal. The broadcast signal may be implemented as a TV broadcast signal, a radio broadcast signal, and a data broadcast signal, among others. The broadcast signal may further include a data broadcast signal combined with a TV or radio broadcast signal.
Examples of broadcast associated information may include information associated with a broadcast channel, a broadcast program, a broadcast service provider, and the like.

Referring to
The image frames processed by the camera 121 may be stored in the memory 160 or transmitted to an external device through the wireless communication unit 110. Two or more cameras 121 may be provided according to the use environment.
The microphone 122 receives an external audio signal through a microphone in a phone call mode, a recording mode, a voice recognition mode, and the like, and processes the audio signal into electrical voice data. The processed voice data may be converted and outputted into a format that is transmittable to a mobile communication base station through the mobile communication module 112 in the phone call mode. The microphone 122 may implement various types of noise canceling algorithms to cancel noise generated in a procedure of receiving the external audio signal.
The user input unit 130 may generate input data to control an operation of the terminal. The user input unit 130 may be configured by including a keypad, a dome switch, a touch pad (pressure/capacitance), a jog wheel, a jog switch, and the like.
The sensing unit 140 detects a current status of the mobile terminal 100 such as an open or closed configuration of the mobile terminal 100, a location of the mobile terminal 100, a presence or absence of user contact with the mobile terminal 100, an orientation of the mobile terminal 100, an acceleration/deceleration of the mobile terminal 100, and the like, so as to generate a sensing signal for controlling the operation of the mobile terminal 100. For example, when the mobile terminal 100 is a slide phone type, the sensing unit 140 may sense whether a sliding portion of the mobile terminal is open or closed. Furthermore, the sensing unit 140 may sense the presence or absence of power provided by the power supply unit 190, the presence or absence of a coupling between the interface unit 170 and an external device. Meanwhile, the sensing unit 140 may include a proximity sensor 141.
Moreover, the sensing unit 140 may measure the surrounding noise (for example, 20 dB) of the mobile terminal 100 to generate a sensing signal or measure the surrounding brightness of the mobile terminal 100 to generate a sensing signal.
The output unit 150 is configured to generate an output associated with visual sense, auditory sense or tactile sense, and may include a display unit 151, an audio output module 152, an alarm unit 153, a haptic module 154, a projector module 155, and the like.
The display unit 151 may display (output) information processed in the mobile terminal 100. For example, when the mobile terminal 100 is in a phone call mode, the display unit 151 may display a User Interface (UI) or a Graphic User Interface (GUI) associated with a call. When the mobile terminal 100 is in a video call mode or capture mode, the display unit 151 may display a captured image and/or received image, a UI or GUI.
The display unit 151 may include at least one of a Liquid Crystal Display (LCD), a Thin Film Transistor-LCD (TFT-LCD), an Organic Light Emitting Diode (OLED) display, a flexible display, and a three-dimensional (3D) display.
Some of those displays may be configured with a transparent or optical transparent type to allow viewing of the exterior through the display unit, which may be called transparent displays. An example of the typical transparent displays may include a transparent LCD (TOLED), and the like. Under this configuration, a user can view an object positioned at a rear side of a mobile terminal body through a region occupied by the display unit 151 of the mobile terminal body.
Two or more display units 151 may be implemented according to a configured aspect of the mobile terminal 100. For instance, a plurality of the display units 151 may be arranged on one surface to be spaced apart from or integrated with each other, or may be arranged on different surfaces.
When the display unit 151 and a touch sensitive sensor (hereinafter, referred to as a “touch sensor”) have an interlayer structure (hereinafter, referred to as a “touch screen”), the display unit 151 may be used as an input device in addition to an output device. The touch sensor may be implemented as a touch film, a touch sheet, a touch pad, and the like.
The touch sensor may be configured to convert changes of a pressure applied to a specific part of the display unit 151, or a capacitance occurring from a specific part of the display unit 151, into electric input signals. The touch sensor may be configured to sense not only a touched position and a touched area, but also a touch pressure at which a touch object body is touched on the touch sensor.
When there is a touch input to the touch sensor, the corresponding signals are transmitted to a touch controller. The touch controller processes the signal(s), and then transmits the corresponding data to the controller 180. Accordingly, the controller 180 may sense which region of the display unit 151 has been touched.
The proximity sensor 141 may be arranged at an inner region of the mobile device 100 surrounded by the touch screen, or adjacent to 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 to sense the presence or absence of an object approaching to a surface to be sensed, or an object disposed adjacent to a surface to be sensed, by using an electromagnetic field or infrared rays without a mechanical contact. The proximity sensor 141 has a longer lifespan and a more enhanced utility than a contact sensor.
The proximity sensor 141 may include an optical transmission type photoelectric sensor, a direct reflective type photoelectric sensor, a mirror reflective type photoelectric sensor, a high-frequency oscillation proximity sensor, a capacitance type proximity sensor, a magnetic type proximity sensor, an infrared rays proximity sensor, and so on. When the touch screen is implemented as a capacitance type, the proximity of a pointer having conductivity to the touch screen is sensed by changes of an electromagnetic field. In this case, the touch screen (touch sensor) may be categorized into a proximity sensor.
Hereinafter, for the sake of convenience of brief explanation, a behavior that the pointer is positioned to be proximate onto the touch screen without contact will be referred to as a “proximity touch”, whereas a behavior that the pointer substantially comes in contact with the touch screen will be referred to as a “contact touch”. For the position corresponding to the proximity touch of the pointer on the touch screen, such position corresponds to a position where the pointer faces perpendicular to the touch screen upon the proximity touch of the pointer.
The proximity sensor senses a proximity touch, and a proximity touch pattern (e.g., proximity touch distance, proximity touch direction, proximity touch speed, proximity touch time, proximity touch position, proximity touch moving status, etc.). Information relating to the sensed proximity touch and the sensed proximity touch patterns may be output onto the touch screen.
The audio output module 152 may output audio data received from the wireless communication unit 110 or stored in the memory 160, in a call-receiving mode, a call-placing mode, a recording mode, a voice recognition mode, a broadcast reception mode, and so on. The audio output module 152 may output audio signals relating to the functions performed in the mobile terminal 100 (e.g., sound alarming a call received or a message received, and so on). The audio output module 152 may include a receiver, a speaker, a buzzer, and so on.
The alarm 153 outputs signals notifying occurrence of events from the mobile terminal 100. The events occurring from the mobile terminal 100 may include call received, message received, key signal input, touch input, and so on. The alarm 153 may output not only video or audio signals, but also other types of signals such as signals notifying occurrence of events in a vibration manner. Since the video or audio signals can be output through the display unit 151 or the audio output unit 152, the display unit 151 and the audio output module 152 may be categorized into part of the alarm 153.
The haptic module 154 generates various tactile effects which a user can feel. A representative example of the tactile effects generated by the haptic module 154 includes vibration. Vibration generated by the haptic module 154 may have a controllable intensity, a controllable pattern, and so on. For instance, different vibration may be output in a synthesized manner or in a sequential manner.
The haptic module 154 may generate various tactile effects, including not only vibration, but also arrangement of pins vertically moving with respect to a skin being touched, air injection force or air suction force through an injection hole or a suction hole, touch by a skin surface, presence or absence of contact with an electrode, effects by stimulus such as an electrostatic force, reproduction of cold or hot feeling using a heat absorbing device or a heat emitting device, and the like.
The haptic module 154 may be configured to transmit tactile effects through a user's direct contact, or a user's muscular sense using a finger or a hand. The haptic module 154 may be implemented in two or more in number according to the configuration of the mobile terminal 100.
A projector module 155 as a constituent element for performing an image project function using the mobile terminal 100 may display an image similar to or an image at least of which is different from that displayed on the display unit 151 on an external screen or wall.
Specifically, the projector module 155 may include a light source (not shown) configured to generate light (for example, laser light) for displaying an image on the outside, an image generation means (not shown) for generating an image to be displayed on the outside using the light generated by the light source, and a lens (not shown) for displaying an image on the outside at a predetermined focal distance. Furthermore, the projector module 155 may include an apparatus (not shown) capable of mechanically moving the lens or an entire module to adjust an image projection direction.
The projector module 155 may be divided into a Cathode Ray Tube (CRT) module, an LCD (Liquid Crystal Display) module, a Digital Light Processing (DLP) module, and the like. In particular, the DLP module is operated in a method of projecting an image generated by reflecting light generated from the light source on a Digital Micromirror Device (DMD) chip in an enlarged manner, and thus beneficial in fabricating a small-sized projector module 155.
Preferably, the projector module 155 may be provided on a lateral surface, a front surface or a rear surface of the mobile terminal 100 in the length direction. Of course, the projector module 155 may be provided even at any location of the mobile terminal 100 according to the need.
Next, a holography module 156 may include a holography storage medium and a holography output module to project a hologram image on the outside.
The holography storage medium as a storage medium for recording an interference pattern generated when an object wave and a reference wave are interfered with each other is formed of a material that responds according to the intensity of light such as a photopolymer.
Here, the holography output module may irradiate a reproduction wave similar to a reference wave on the holography storage medium according to the control of the controller 180, and display a hologram image generated through a diffraction phenomenon between the irradiated reproduction wave and the interference pattern recorded on the holography storage medium.
A specific method for projecting a hologram image will be described below in detail with reference to
Furthermore, as described above, it has been described that both the holography storage medium and holography output module are integrated into the holography module 156 and implemented at the same time, but it is merely a simple example, and may be also included in the mobile terminal 100 in a separate configuration.
The memory 160 may store a program for processing and controlling the controller 180, and perform a function for temporarily storing data (for example, phone books, messages, audio, still images, moving images, etc.). The memory 160 may also store use frequency for each of the data (for example, use frequency for each phone number, each message, and each multimedia) at the same time. Furthermore, the memory 160 may store data for the vibration and sound of various patterns displayed while making a touch input on the touch screen.
Moreover, in order to support the hologram image projection of the holography module 156, information on holography interference patterns may be stored therein. In other words, it may be possible to output a user's voice, an execution result of an application, and the like to the outside through the holography module 156 using the information stored in the memory 160.
The memory 160 may be implemented using any type of suitable storage medium including a flash memory type, a hard disk type, a multimedia card micro type, a memory card type (e.g., SD or DX memory), 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 disk, optical disk, and the like. Also, the mobile terminal 100 may operate in association with a web storage which performs the storage function of the memory 160 on the Internet.
The interface unit 170 may generally be implemented to interface the mobile terminal with external devices connected to the mobile terminal 100. The interface unit 170 may allow a data reception from an external device, a power delivery to each component in the mobile terminal 100, or a data transmission from the mobile terminal 100 to an external device. The interface unit 170 may include, for example, wired/wireless headset ports, external charger ports, wired/wireless data ports, memory card ports, ports for coupling devices having an identification module, audio Input/Output (I/O) ports, video I/O ports, earphone ports, and the like.
The identification module may be configured as a chip for storing various information required to authenticate an authority to use the mobile terminal 100, which may include a User Identity Module (UIM), a Subscriber Identity Module (SIM), and the like. Also, the device having the identification module (hereinafter, referred to as “identification device”) may be implemented in a type of smart card. Hence, the identification device can be coupled to the mobile terminal 100 via a port.
Furthermore, the interface unit may serve as a path for power to be supplied from an external cradle to the mobile terminal 100 when the mobile terminal 100 is connected to the external cradle or as a path for transferring various command signals inputted from the cradle by a user to the mobile terminal 100. Such various command signals or power inputted from the cradle may operate as signals for recognizing that the mobile terminal 100 has accurately been mounted to the cradle.
The controller 180 typically controls the overall operations of the mobile terminal 100. For example, the controller 180 performs the control and processing associated with telephony calls, data communications, video calls, and the like. The controller 180 may include a multimedia module 181 which provides multimedia playback. The multimedia module 181 may be configured as part of the controller 180 or as a separate component.
Furthermore, the controller 180 can perform a pattern recognition processing so as to recognize writing or drawing input carried out on the touch screen as text or image.
The power supply unit 190 receives external and internal power to provide power required for various components under the control of the controller 180.

For example, the first manipulation unit 131 may be used to receive a command, such as start, end, scroll, or the like, and the second manipulation unit 132 may be used to receive a command, such as controlling a volume level being outputted from the audio output unit 152, or switching it into a touch recognition mode of the display unit 151.
Front Surface Touch
Here, an operation method in which the display unit 151 and the touch pad 135 are associated with each other will be described with reference to
Various kinds of visual information may be displayed on the display unit 151. The visual information may be displayed in the form of a character, a numeral, a symbol, a graphic, an icon, and the like.
For an input of the visual information, at least one of a character, a numeral, a symbol, a graphic, and an icon may be displayed with a predetermined arrangement so as to be implemented in the form of a keypad. Such a keypad may be referred to as a so-called “virtual keypad.”
The display unit 151 may be operated over an entire region or operated in a plurality of divided regions. In the latter case, it may be configured such that the plurality of regions are operated in a mutually associated manner.
For example, an output window 151a and an input window 151b are displayed on an upper portion and a lower portion of the display unit 151, respectively. The output window 151a and input window 151b are regions assigned to output and input information, respectively. A virtual keypad 151c displayed with a numeral for entering a phone number or the like is displayed on the input window 151b. Upon touching the virtual keypad 151c, a numeral or the like corresponding to the touched virtual keypad is displayed on the output window 151a. When manipulating the first manipulation unit 131, a call connection for the phone number displayed on the output window 151a is attempted.
In addition to the input schemes disclosed in the above embodiments, the display unit 151 or touch pad 135 may be configured to receive a scroll-bases touch input. The user may scroll the display unit 151 or touch pad 135 to move an object displayed on the display unit 151, for example, a cursor or pointer located at the icon or the like.

Said one function may be an activation or deactivation of the display unit 151 or the touch pad 135.
Hereinafter, a hologram image expression method of a mobile terminal and a structure for the same that are applicable to the embodiments of the present disclosure will be described.
Prior to describing a specific hologram image, the shape of a mobile terminal including a holography module 156 will be described with reference to
The holography module 156 may be disposed and mounted on a front or rear surface of the mobile terminal.
First, referring to
Furthermore, as illustrated in
A hologram image implemented through the holography module 156 may include both planar and stereoscopic images.
Here, the stereoscopic image implemented through the holography module 156 may be largely divided into 2D and 3D stereoscopic images.
The 2D stereoscopic image mode as a monoscopic mode for providing the same image to both eyes is a method of disposing polyhedrons generated through one or more points, lines, planes, and their combinations in a virtual three-dimensional space according to the control of the controller 180, and displaying an image viewed from a particular point of sight.
Next, the 3D stereoscopic image mode as a stereoscopic mode for providing different images to both eyes is a method of using a principle in which humans feel a three-dimensional effect when viewed through their naked eyes. In other words, both human eyes view different planar images when viewing the same object due to a distance between each other. Such different planar images are transferred to his or her brain through retinas, and the brain combines them to feel the depth and reality of a stereoscopic image. Accordingly, there is a certain difference between each person, but binocular disparity due to a distance between both eyes causes to feel a three-dimensional effect, and therefore, the 3D stereoscopic image mode is a method of displaying an image using such binocular disparity.
Hologram images generated through the holography module 156 which will be described later may include both the foregoing planar and stereoscopic images, but for the sake of convenience of explanation, it will be described below by assuming that they are displayed in a 2D stereoscopic image mode. However, the content of the present disclosure will not be necessarily limited to this.
Hereinafter, a hologram image expression method of a mobile terminal applicable according to the embodiments of the present disclosure and a structure therefor will be described in detail.
A hologram image expression method may be understood as an image display method of simultaneously accumulating and reproducing all information, namely, both amplitudes and phases, carried by light, which is a wave, whereas an image in the related art records only the distribution of bright and dark sides of an object.
A hologram image expression method will be described with reference to
First, referring to
When one of the two beams is illuminated on a subject 507, light can be reflected from a surface of the subject, and hereinafter, the beam is referred to as an object wave.
Furthermore, the other beam may be diffused through a lens and directly illuminated on a front surface of the holographic photosensitive material 505, and hereinafter, the beam is referred to as a reference wave.
An object wave and a reference wave cause an interference phenomenon on the holographic photosensitive material 505 to form 500-1,500 very delicate and intricate patterns per millimeter. Here, a photo recorded with such interference patterns is referred to as a hologram.
Then, when a light beam such as a reference wave generated as illustrated in
Here, an initial object is seen when viewed within a reproduced wavefront but the object is seen as if it is located therewithin. Then, if the point of view is moved, then the object is seen as if it is seen from a varying object viewing position. Furthermore, since an original wave front of the object is reproduced, it has a characteristic of being interfered with a wavefront coming from a very slightly modified object.
A hologram image expression method may be divided into a transmission type hologram image expression mode and a reflection type hologram image expression mode according to the reproduction method.
(1) Transmission Type Hologram Image Expression Mode
It is a mode in which light is illuminated from the rear side of a hologram to view an image that has passed therethrough in front of the hologram. In a transmission type hologram image expression mode, an object wave and a reference wave are exposed on a photo film in the same direction during the fabrication, and it has a characteristic in which the color of the generated hologram image is clear and bright.
(2) Reflection Type Hologram Image Expression Mode
It is a mode in which light is illuminated from the front side of a hologram to view an image reflected therefrom in front of the hologram, and fabricated such that the directions of an object wave and a reference wave are incident in opposite directions to each other. It has a characteristic in which the hologram image generated in the reflection type hologram image expression mode has an excellent three-dimensional effect.
The transmission type hologram image expression mode and reflection type hologram image expression mode will be described in detail with reference to
Referring to
Here, the object wave and reference wave illuminated on a film cause an interference phenomenon to form an interference pattern, and the interference pattern is recorded on the film 607.
In other words, as illustrated in
Then, as illustrated in
Next,
Referring to
However, contrary to
In other words, as illustrated in
The foregoing films 607, 707 are expressed as a holography storage medium in the present specification, and another constituent element capable of emitting light onto the film to produce a hologram image is expressed as a holography output module.
As described above, for the sake of convenience of explanation, according to the present specification, it is described that a holography storage medium and a holography output module are integrated into a holography module 156 and implemented at the same time, but it is merely a simple example, and they may be also included in the mobile terminal 100 in a separate configuration.
Furthermore, for the sake of convenience of explanation, it is assumed that a mobile terminal described below includes at least one of constituent elements illustrated in
Typically, an arrow or finger shaped graphic for indicating a specific object or selecting a menu on the display unit 151 is referred to as a pointer or cursor.
However, the pointer may also denote a finger or stylus pen for touch manipulation or the like.
Accordingly, in order to clearly distinguish the two, according to the present specification, a graphic displayed on the display unit 151 is referred to as a cursor, and a physical means such as a finger or stylus pen capable of performing a touch, a proximity touch, and a gesture is referred to as a pointer.
Furthermore, as described above, a hologram image may include both a planar image and a stereoscopic image, but for the sake of convenience of explanation, it will be described below by assuming that the hologram image is displayed in a 2D stereoscopic image mode.
On the other hand, according to an embodiment of the present disclosure, a hologram image may be displayed according to the set holography pattern.
The holography pattern denotes a pattern in which a hologram image projected through the holography module 156 is varied with preset patterns according to time and provided to the user.
The holography pattern may be set in various ways using the following schemes.
First, a distance difference between the holography output module and hologram image may vary according to time to set up a holography pattern.
In other words, a distance difference between the holography output module 156 and hologram image may vary according to time to move a hologram image projected through the holography module 156 in a vertical direction, thereby setting up a predetermined holography pattern.
Next, the shape of a hologram image projected from the holography module 156 may vary according to time to set up a holography pattern.
For example, the controller 180 may control a hologram image projected from the holography module 156 to have a circular shape and then control the hologram image to be changed to a rectangular shape according to the flow of time. Through this, a hologram image may be changed to various shapes according to time, thus setting up a holography pattern.
Furthermore, a method of moving a hologram image projected through the holography module 156 in a horizontal direction or rotating the hologram image may be also applicable thereto.
In other words, a projected hologram image may be horizontally moved, rotated or rotated while being horizontally moved while maintaining a distance difference between the holography module and hologram image, thereby setting up a holography pattern.
Furthermore, the color or size of a projected hologram image may be modified or the hologram image may be controlled to be on and off according to time, thereby setting up a holography pattern. Moreover, the setting of a holography pattern may be also allowed through projection brightness, refresh rate, lights illumination, vibration feedback, sound insertion, image insertion, repeated projection, and the like.
However, it has been described in the above by assuming that a holography pattern is set by an individual factor, but the holography pattern may be also set by a plurality of elements.
For example, the holography pattern may be set to move and rotate the projected hologram image in a horizontal direction while changing a distance difference between the holography module 156 and hologram image according to time.
Furthermore, it has been described in the above by assuming that a holography pattern is set for the entire hologram image, but it is merely exemplary content, and the holography pattern may be also applicable only to partial region of the hologram image.
Hereinafter, first type mobile terminals in which any one body supplying light as a mobile terminal for generating a hologram image is coupled to another body to generate a hologram image will be described with respect to

The coupling portion 1130 may be formed with a through hole formed on any one lateral surface of the second body 1120, and the first body 1110 may be detachably coupled to the through hole. The through hole constituting the coupling portion 1130 is sufficiently concave inward, and thus the first body 1110 coupled thereto is formed not to be protruded in an outer direction of the second body 1120.
The coupling portion 1130 may include a light control unit and a data transmission unit. The light control unit is formed to control light emitted from a first light source. The light control unit is formed to be open so as to transmit light when the first body 1110 is coupled thereto, and formed to be closed so as to seal the second body 1120 when the first body 1110 is separated therefrom.
The data transmission unit may electrically connect the first body 1110 to the second body 1120 to transmit and receive signals.
Furthermore, the first body 1110 may be coupled to the second body 1120 in an inclined manner.
In addition, the first body 1110 may include at least one light source. The light source may be any one of a lamp, a laser and an LED, or formed by combining at least two of them. Such a light source is merely an example, and the light source may be formed to include another unit emitting light.

For an example, as illustrated in the drawing, the first irradiation unit 2150 may include one mirror, and the second irradiation unit 2160 may be formed to include three mirrors so as to form a predetermined path.

Furthermore, the mirror may be formed to include a diffractive optical element such as a holographic optical element (HOE) or diffractive optical component (DOE).
In this manner, the mirror may form an optical path from a first light source to a first film. In other words, a path passing through the beam splitter 2121 from the first light source to the first film via the first irradiation unit 2150 may form a first path, and a path passing through the beam splitter 2121 from the first light source to the first film via the second irradiation unit 2160 may form a second path.
One end of the filming unit 2140, first irradiation unit 2150 or second irradiation unit 2160 is fixed, and the other end thereof is formed around said one end in a revolvable manner to control the angle of light irradiated to the filming unit 2140.
The filming unit 2140 may be layered to cover one surface of the display 2170. The display 2170 may be a second light source radiating light toward the filming unit 2140.

In addition, a first path passes through the beam splitter 2321 from the first light source via the first irradiation unit 2350 and directly extends to a predetermined space on the display 2370.
Due to this, light that has passed through the first path and light that has passed through the second path are combined with each other in a predetermined space on the display 2370 to implement a hologram composite image.
Here, the first irradiation unit 2350 may include one mirror and one lens to form a first path, and the second irradiation unit 2360 may include three lenses to form a second path.

The second path passes through the beam splitter 2521 from the first light source via the display 2570, first filming unit 2540 and reflective sheet 2582, and then light is irradiated on the first filming unit 2540 again and extended onto one surface of the display 2570 via the reflective portion 2290.
Due to this, light that has passed through the first path and light that has passed through the second path are combined with each other in a predetermined space on the display 2570 to implement a hologram composite image.
A touch panel 2580 covering the first filming unit 2540 may include a lens 2581 and a reflective sheet 2582. The reflective sheet 2582 is formed such that incident light irradiates a predetermined region of the first filming unit 2540.

The filming unit 11110 may include an interference pattern to implement a hologram image.
The filming unit 11110 may be formed through a slit passing through an inner side and an outer side of the body in a replaceable manner. For an example, the filming unit 11110 may be formed in a slidably movable manner to be detachably coupled to the body. In this manner, the filming unit 11110 may be replaced to implement more various hologram images.
Furthermore, the filming unit 11110 may be formed in a flexible manner or at least part of the filming unit 11110 may be fixed on a substrate. The filming unit 11110 fixed to the substrate may reduce image distortion.
In addition, a touch panel may be formed to cover the filming unit 11110. The touch panel may be formed to include a transparent conductive pattern to sense a user's touch.
The light source 11121 may be any one of a lamp, a laser and an LED, or formed by combining at least two of them. Such a light source 11121 is merely an example, and the light source 11121 may be formed to include another unit emitting light.
The irradiation unit 11122 may be formed such that light radiated from the light source 11121 is irradiated at a predetermined angle toward one surface of the filming unit 11110. The irradiation unit 11122 may include one or more optical mirrors.
According to the following embodiments, an optical mirror is taken as an example, but a prism having at least two optical planes may be used instead of the optical mirror.
The mirror may be formed with a plane shape or formed to include a partially concave or convex portion. When at least part of the mirror is formed to be concave or convex, it may be possible to more effectively illuminate the filming unit 11110 having a rectangular shape. Furthermore, the mirror may be formed to include a diffractive optical element such as a holographic optical element (HOE) or diffractive optical component (DOE).
The irradiation unit 11122 and light source 11121 may be formed with one optical module 11120 as an integral body. Here, a distance between the irradiation unit 11122 and light source 11121 may be controlled, and the irradiation unit 11122 and light source 11121 may be formed in an angle-controlled manner, respectively, thereby more effectively controlling light toward the filming unit 11110.
On the contrary to
Here, the display may be another light source 11221 radiating light toward the filming unit 11210.
The display may include a light-emitting element such as active matrix organic light emitting diodes (AMOLED), for an example, when formed in a non-transparent manner, and may include a top-emitting organic light emitting diodes (TOLED), for an example, when formed in a transparent manner.
When formed in a non-transparent manner, an optical member may be coated on one surface of the display to inject or reflect light toward the filming unit 11210.
When the display is formed in a transparent manner, a reflective portion may be formed on the other surface of the display to reflect the incident light.
The filming unit 11310 may be formed to relatively move with respect to the irradiation unit 11322. Different hologram images may be formed respectively according to the angle of light irradiated on one surface of the filming unit 11310.
To this end, a hologram pattern formed on the filming unit 11310 may be formed to display a first hologram image at a first irradiation angle, and formed to display a second hologram image at a second irradiation angle. In other words, the filming unit 11310 may include a plurality of hologram patterns to display different hologram images, respectively, according to the angle.
The angle of the irradiation unit 11322 and the angle of the filming unit 11310 may be controlled to control an irradiation angle.
In order to control the angle of the filming unit 11310, a hinge is formed at one end of the irradiation unit 11322, and the irradiation unit 11322 is formed to revolve around the hinge, or a shaft is connected to any one portion of the irradiation unit 11322, and the irradiation unit 11322 is formed to revolve around the shaft.
Furthermore, the irradiation unit 11322 may be formed in an entirely revolvable manner as illustrated in
As illustrated in the drawing, the optical module 11520 may be coupled to one end of the terminal body 11500 in a revolvable manner.
The terminal body 11500 and optical module 11520 may be hinge-coupled to each other.
Here, the filming unit 11510 may include a plurality of holography patterns to display different hologram images, respectively, according to the angle.
