  Hereinafter, a display device according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the display apparatus 100 supports a main body 110, a main body 110 that forms an appearance, a display panel 120 that is installed in the main body 110 and displays an image, and a lower portion of the main body 110. A stand 130.

  The display panel 120 can be constituted by a liquid crystal display panel (Liquid Crystal Display Panel) or an organic light emitting diode panel (Organic Light Emitting Diodes Panel). In this embodiment, the display panel 120 is a liquid crystal display panel.

  As shown in FIG. 2, the main body 110 includes a bezel 111 a that supports the outer frame of the display panel 120, covers a front case 111 that forms a front end of the main body 110, and a rear side of the display panel 120. A display panel 120 is disposed between the front case 111 and the rear case 112, including a rear case 112 that forms the rear surface of the main body 110. Here, the display panel 120 includes an active region in which an image is displayed and a non-active region that is provided with a pattern that allows an image to be displayed in the active region and is hidden by the bezel 111a.

  The main body 110 is provided with a video call unit 140 that enables a video call through video provided by the display panel 120. In the present embodiment, the video call unit 140 is installed at the center of the upper end of the main body 110, protrudes above the main body 110, and is installed outside the display panel 120.

  As shown in FIG. 2, in order to install the video call unit 140, an installation portion that is formed in a shape corresponding to the video call unit 140 at the center of the upper end of the rear case 112 and in which the video call unit 140 is installed. 112a is provided. In the present embodiment, the installation portion 112 a protrudes upward from the center of the upper end of the rear case 112. The installation portion 112a is opened to the front side so that the front surface of the video call unit 140 is exposed to the front side, and an operation hole that exposes an adjustment wheel 144 described later to the rear side is provided on the rear surface of the installation portion 112a. 112b is provided.

  The video call unit 140 is a unit using MoIP (Multimedia over Internet Protocol), and as shown in FIGS. 3 and 4, a camera module 141 and a camera module 141 for photographing a user who is a subject. And a pair of microphone modules 142 that input the user's sound after being converted into an electrical signal. In addition, the video call unit 140 forms an appearance of the video call unit 140 and includes a housing 143 in which the camera module 141 and the microphone module 142 are housed. The housing 143 is coupled to each other in the front-rear direction, and the front housing 143F. And a rear housing 143R. Further, as shown in FIG. 5, the video call unit 140 includes a communication unit 145 for communication with a remote controller (not shown), a shutter glass (not shown) used for viewing 3D TV, and the like. You can also.

  Accordingly, the user is photographed by the camera module 141 of the video call unit 140 and the user's sound is input through the microphone module 142, so that the user can make a video call through the display device 100.

  The video call unit 140 includes an adjustment wheel 144 that is rotatably installed on the rear side of the camera module for adjusting the tilt angle of the camera module 141, and a plurality of units for transmitting the rotation of the adjustment wheel 144 to the camera module 141. Gear 144a. Accordingly, when the user applies a force to the adjustment wheel 144 to rotate the adjustment wheel 144, the rotational motion of the adjustment wheel 144 is transmitted to the camera module 141 through each gear 144a, and the camera module 141 rotates.

  In the present embodiment, as described above, the operation of the microphone module can be turned on (ON) / off (OFF) depending on the rotation angle of the camera module 141. That is, when the camera module 141 rotates and the lens of the camera module 141 goes to the front of the display device 100, the microphone module 142 is turned on (ON), and a video call through the display device is enabled. When the camera module 141 rotates and the lens of the camera module 141 does not face forward, the operation of the microphone module 142 is turned off (OFF), and a video call through the display device 100 becomes impossible.

  As shown in FIG. 2, one end of each cable 146 for transmitting various signals generated by the video call unit 140 is connected to the video call unit 140, and the other end of the cable 146 is connected to the video call unit. A circuit board 150 for controlling 140 is connected.

In this case, a through hole 321 having a shape corresponding to the video call unit 340 is formed in the display panel 320, and light and sound are transmitted to the video call unit 340 through the through hole 321.

  In this embodiment, the camera module 141 is manually rotated by the user applying force to the camera module 141 through the adjustment wheel 144. However, the present invention is not limited to this. It is also possible to rotate the camera module through a drive device (not shown). When using a driving device such as a motor, a sensor (not shown) is installed on the display device together with the driving device, and the camera module automatically rotates according to the position of the user detected by the sensor, or a remote control It is also possible to configure the camera module to be rotated by the driving device in accordance with the operation or button operation provided on the display device.

  In the present embodiment, the microphone module 142 is configured such that sound is input only from the front side, but is not limited to this, and the bidirectional microphone is configured to input sound from the front and rear sides. A microphone module is installed in a hollow tube (not shown) formed in a module and open to the front side and the rear side, and sound is input from the front side and the rear side of the display device. It is also possible.

  When configured in this way, since the sound from both sides of the tube, that is, the front side and the rear side of the display device is guided by the tube and transmitted to the front and rear sides of the microphone module, the video call unit is applied. Regardless of the thickness of the display device, the sound transmitted from the front side of the display device and the sound transmitted from the rear side can be input without phase difference.

  In this embodiment, the installation part 112a where the video call unit 140 is installed is provided in the rear case 112, and the holder part 111d is provided in the front case 111, but the present invention is not limited to this.
