At the same time, the controller 180 projects the 3D image data through the first projector module 155. In this case, the type of polarization filter disposed on the front surface of the first projector module 155 of the mobile communication terminal 100 is different from the type of the third polarization filter 157 '. For example, when the third polarization filter 157 ′ is a vertical polarization filter, the polarization filter disposed in front of the first projector module 155 of the mobile communication terminal 100 is a horizontal polarization filter. Accordingly, the 3D image data is simultaneously projected by the first projector module 155 and the second projector module 155 ′, thereby projecting the 3D image data into an external space as a 3D image. That is, the user may check the 3D image through the external space.

Herein, an embodiment in which the first polarization filter 156, the second polarization filter 157, and the third polarization filter 157 ′ may be disposed will be described. The second projector module 155 ', where 156 is a vertically polarized filter, is fixedly disposed on the front surface of the first projector module 155, and the third polarized filter 157' is a horizontal polarized filter. ) Is fixed to the front of the In this case, the second polarization filter 157 and the motor 158 are not necessary.

In a second embodiment, the first polarization filter 156 and the second polarization filter 157 may be manually moved instead of the motor 158. That is, each of the first polarization filter 156 and the second polarization filter 157 is connected with a moving means which can be manually moved by the user, and the user uses the first polarizing filter using the moving means. Any one of the emitter 156 and the second polarization filter 157 may be disposed on the front surface of the projector module 155.

In a third embodiment, the controller 180 recognizes the type of the third polarization filter 157 ', and a filter of a type different from that of the third polarization filter 157' is the first projector module 155. The motor 158 is controlled to be disposed in front of the. For example, when the third polarization filter 157 ′ is a vertical polarization filter, the controller 180 may include a filter that is a horizontal polarization filter among the first polarization filter 156 and the second polarization filter 157. The motor 158 is controlled to be disposed in the first projector module 155.

Accordingly, a user usually uses a mobile communication terminal equipped with one projector module to project two-dimensional image data. On the other hand, when the 3D image data is to be projected, the user may project the 3D image data by connecting the projector accessory to the mobile communication terminal.

In addition, by projecting three-dimensional image data using a mobile communication terminal provided with one projector module, it is possible to significantly reduce the volume of flying to the mobile communication terminal equipped with two projector modules.

In addition, by providing a polarizing filter therein, the user can view the 3D image data without wearing separate glasses.

Then, the controller 180 determines whether the second interface 170 ′ of the second mobile communication terminal 100 ′ is connected to the first interface 170. Alternatively, the controller 180 determines whether the first wireless communication unit 110 and the second wireless communication unit 110 'are connected and synchronized. Here, the first wireless communication unit 110 and the second wireless communication unit 110 ′ may be connected (“synchronized”) by the following process.

When the motor control signal is input, the controller 180 'controls the second motor 158 to arrange the third polarization filter on the front surface of the second projector module 155'. Simultaneously or sequentially, the first controller 180 controls the first motor 158 such that the second polarization filter 157 is disposed in front of the first projector module 155. In this case, the types of the first polarization filter 156 and the third polarization filter 156 'are the same, and the types of the second polarization filter 157 and the fourth polarization filter 157' are the same. Next, the controller 180 transmits the selected three-dimensional image data to the second mobile communication terminal 100 ′ through the first wireless communication unit 110 or the first interface unit 170, thereby transmitting the second 3D image data. The 3D image data is projected through the projector module 155 '. At the same time, the controller 180 projects the 3D image data through the first projector module 155. Accordingly, the three-dimensional image data is simultaneously projected by the first projector module 155 and the second projector module 155 ', thereby projecting the three-dimensional image to the external space. That is, the user may check the 3D image through the external space.

Accordingly, three-dimensional image data can be projected using two mobile communication terminals. Therefore, since one projector module is provided in one mobile communication terminal, the volume can be greatly reduced compared to the mobile communication terminal provided with two projector modules.

That is, a portion of the first mobile communication terminal 100 is connected to one side of the connection unit 510, and a portion of the second mobile communication terminal 100 ′ is connected to the other side of the connection unit 510. In this case, the first mobile communication terminal 100 is disposed at the front side, and the second mobile communication terminal 100 'is disposed at the rear side. In addition, since the connection unit 510 is configured to be rotatable, the user may rotate the first mobile communication terminal 100 and the second mobile communication terminal 100 'around the connection unit 510.
