3 is a diagram illustrating an operation principle of a mobile terminal according to an embodiment of the present invention.

As shown in the figure, the mobile terminal 100 according to an embodiment of the present invention can display a 3D image through the display unit 151.

The display unit 151 is a part for displaying an image by a control signal of the control unit (180 in Fig. 1). In addition, the display unit 151 may include a touch screen for receiving a touch signal from a user. In the case where a touch screen is included, the display unit 151 may serve as both display means and input means.

The display unit 151 may display a 3D (3-dimensional) image. The three-dimensional image refers to a three-dimensional image that is displayed on the display unit 151, which is flat, but is felt by the user. A method of displaying the 3D image by the display unit 151 is as shown in FIG. 3, a cross-sectional view of the display unit 151 of the mobile terminal 100 is schematically shown. As shown in the figure, when an image is displayed on the LCD layer L1, the image can be projected onto the 3D film layer RO, and the image projected on the 3D film layer RO can be displayed on the front glass layer L2 And can be recognized through the left eye LE and the right eye RE of the user.

The 3D film layer (RO) can separate the image displayed on the LCD region (L1) into a left eye (LE) image and a right eye (RE) image. That is, in the image displayed on the LCD layer L1, the 3D film layer RO passes through the prism-like lower structure and is diffracted or refracted. The image is projected in the direction of the left eye LE and in the direction of the right eye RE It can be separated into an image to be incident. A light source unit (not shown) may be provided on the left and right sides of the display unit 151. The 3D film layer RO may be composed of a refractory layer including a crystal crystal whose direction is switched when a voltage is applied and a refracting body coupled thereto.

The refractive body may be provided in a triangular or prismatic shape. The image diverged from the LCD layer L1 can be refracted in the right and left directions through the refracting body.

Crystal crystals can have polarity. When a voltage is applied, the crystal crystal can be aligned in a certain direction. Since the crystal crystal is coupled to the refracting body, a specific voltage can be applied by the control signal of the control unit (180 in FIG. 1), and the crystal can be aligned in a certain direction when the voltage is applied. When the crystals are aligned in a certain direction, the refracting body can be aligned in a certain direction to refract the image in a certain direction. Since the direction of the voltage direction or the on / off of the voltage is controlled according to the direction of the mobile terminal 100, the direction of the refracting body constituting the 3D film layer RO can be switched, 3D images can be implemented.

The left and right sides of the light source unit (not shown) can be rapidly turned on and off sequentially. The left eye LE and the right eye RE of the user are separated from each other by the first and second images OB1 and OB2 separated from each other when the image is separated through the 3D film layer RO and the left and right light sources , OB2). The first and second images OB1 and OB2 obtained through the left eye LE and the right eye RE may be synthesized into one image in the user's brain to be a composite image OB3. The synthesized image OB3 obtained from the first and second images OB1 and OB2 having a slight time difference and an image difference can be recognized as a three-dimensional image. The three-dimensional image means an image which is felt to give the user a three-dimensional feeling as described above. However, since the three-dimensional image, which is meant in the present invention, can not be displayed in the drawings for explaining each embodiment of the present invention, the detailed description will be omitted.

In order for the composite image OB3 to be recognized as a three-dimensional image, it is necessary that the directions of the imaginary line connecting the user's eyes LE and RE and the orientation of the 3D film layer RO be substantially orthogonal. That is, since the image displayed on the LCD layer L1 passes through the 3D film layer RO and is diffracted or refracted leftward and rightward, the user's eyes LE and RE need to be positioned respectively in the direction of diffraction or refraction . If the mobile terminal 100 is rotated 90 degrees about the center of the user's eyes LE and RE at the position shown in FIG. 3, the user may not be able to recognize the three-dimensional image. That is, since the difference between the images input to the left eye LE and the right eye RE decreases or disappears, it means that the user may not recognize the composite image OB3 as a three-dimensional image. In view of this, a plurality of 3D film layers (RO) can be formed.

4 is a view illustrating an exemplary embodiment of a mobile terminal display unit for displaying a 3D image of the present invention.

As shown, the 3D film layer RO may include a first layer RO1 and a second layer RO2.

The first and second layers RO1 and RO2 may have a lattice. In the description of the present invention, the lattice refers to a pattern parallel to each other. That is, the first and second layers RO1 and RO2 have a cross-sectional shape in which a triangular or prismatic lattice is formed.

The 3D film layer RO may be formed by bonding the lattices of the first and second layers RO1 and RO2 to be orthogonal to each other. Since a grid perpendicular to the 3D film layer RO is formed, the user can recognize the 3D image irrespective of the orientation of the mobile terminal 100. [ That is, not only when the user holds the mobile terminal 100 in the longitudinal direction but also when the user holds the mobile terminal 100 in the width direction, the user can effectively display the three-dimensional image. For example, when the user holds the mobile terminal 100 in the longitudinal direction, the first layer RO1 of the 3D film layer RO refracts or diffracts the image in the left and right directions, When the user holds the mobile terminal 100 in the width direction, the second layer RO2 may refract or diffract the image in the left and right directions to distribute the image to the user's eyes LE and RE .

5 and 6 are views showing another embodiment of a mobile terminal display unit for displaying a 3D image of the present invention.

As shown in these drawings, according to the mobile terminal 100 according to another embodiment of the present invention, when the user holds the mobile terminal 100 in the width direction (FIG. 5) to view an image, (FIG. 6) so that the stereoscopic image can be sensed even when the user views the image. The mobile terminal 100 according to another exemplary embodiment of the present invention may include an active matrix organic light emitting diode (AMOLED) light emitting device.

The active organic light emitting diode has a high response speed and can emit light by itself. Therefore, a light source unit (not shown) as in the case of the mobile terminal 100 according to an embodiment of the present invention may not be needed.

5A, the display unit 151 including the active type organic light emitting diode light emitting element has a first surface A1 as a left surface and a second surface A1 as a right surface with respect to the center of the display unit 151, And can be divided into two sides (A2). In the division of the first and second surfaces A1 and A2, one display unit 151 is logically divided into two. As described above, the light emitting device itself can emit light in the active type organic light emitting diode. Therefore, while the first surface A1 is displaying an image, the second surface A2 can be turned off.

As shown in Fig. 5 (b), it is possible to turn on and off the second surface A2 while the first surface A1 is turned off.

As shown in Figs. 5 (a) and 5 (b), the lighting and the light extinguishing can be performed in a fast cycle alternating between the logically divided first and second surfaces A1 and A2. When the first and second surfaces A1 and A2 repeatedly turn on and off alternately at fast cycles and the images displayed at the moment of lighting are slightly different, the left eye (LE in FIG. 3) and the right eye 4 RE) can detect a slightly different image for the same object. As described above, the image recognized through both eyes (LE and RE in FIG. 3) can be consequently synthesized through the brain and recognized as the composite image OB3.

6 (a) and 6 (b), the mobile terminal 100 according to another embodiment of the present invention recognizes a stereoscopic image even when the user holds the mobile terminal 100 in the longitudinal direction . That is, since the light emitting device of the display unit 151 is formed of the active type organic light emitting diode, the first and second surfaces A1 and A2 which are logically divided can be sequentially turned on and off to generate a stereoscopic image.

The direction of the mobile terminal 100 may be detected by any one of an acceleration sensor, a geomagnetism sensor, and a grip sensor included in the sensing unit 140 . For example, the acceleration sensor can sense the movement of the mobile terminal 100 in the width direction (FIG. 5) and in the vertical direction (FIG. 6) (In the case of the horizontal direction), and the grip sensor senses whether the user is moving through the position of the finger holding the body of the mobile terminal 100 It is possible to detect in which direction the terminal 100 is heading. Therefore, the controller (180 in FIG. 1) analyzes signals sensed by any one of these sensors or through these sensors, thereby knowing the direction the mobile terminal 100 is aiming at. The control unit (180 of FIG. 1) that has learned the direction of the mobile terminal 100 can display the image on the display unit 151 in synchronization with the direction.

Synchronization means synchronizing the direction of the body of the mobile terminal 100 with the vertical direction of the image displayed on the display unit 151. The image included in the display unit 151 may have a predetermined vertical direction. Accordingly, when the body of the mobile terminal 100 is positioned in the width direction (FIG. 5) or when the body of the mobile terminal 100 is in the longitudinal direction (FIG. 6) So that it can be displayed.

7 and 8 are views showing a mobile terminal display unit for displaying a 3D image in a part of the display unit.

As shown in these drawings, a 3D image can be displayed only on a partial area of the display unit 151. [ Therefore, it is possible to display the 3D information on the information that should give the user attention.

As shown in FIG. 7, the central area (A4-A5) of the display unit 151 can be set as a 3D image display unit. The control section 180 of Fig. 1 can logically divide the central area A4-A5 into the left area A4 and the right area A5 and display it. The logically divided left side area A4 and the right side area A5 are sequentially blinked and the image is displayed so that the user can recognize the image as a stereoscopic image.

As shown in Fig. 8, a certain arbitrary area (A6-A7) of the display unit 151 can be set as the 3D image display unit. Therefore, the control unit (180 in FIG. 1) can display necessary information in a 3D image without being limited in position.

That is, the user's line of sight may be concentrated on the image PD displayed in the center area, and the most interesting part displayed on the display unit 151 may be the image PD displayed in the center area. Therefore, the image PD displayed in the center area can be displayed as a 3D image, and other areas can be displayed as a 2D image. The image PD displayed in the center area is displayed as a 3D image, so that the user's attention can be more reliably evoked.
