For example, by dividing the screen of the image display apparatus into two screens to the left and the right, different images are displayed on the left split screen and the right split screen so that each user can see the desired image.

However, in the related art, when a plurality of images are displayed, other users also have to view a different image than the desired image, so that they cannot immerse themselves in the desired image and cannot hear the sound (sound) accompanying each screen. There was a problem.

SUMMARY OF THE INVENTION In order to solve the above problem, an object of the present invention is to provide a video display device for simultaneously viewing a plurality of channels in which a plurality of images are simultaneously displayed on a video display device and a plurality of users can view only a desired image. have.

In particular, an object of the present invention is to allow a plurality of users to see only the image they want by different polarization angle of different images by applying polarization technology.

In order to achieve the above object, the present invention provides an image display device for displaying two different images at different polarization angles on one screen, and a polarization angle for displaying each image. It is characterized by consisting of two polarized glasses visible.

The image display device may display two different images on one screen by horizontal interleaving or page flipping.

The image display device is configured by sequentially bonding a display panel (PDP panel, OLED panel, LED panel), a polarizing plate, and a TN liquid crystal panel, or by sequentially bonding a polarizing plate, a color liquid crystal display panel, a polarizing plate, and a TN liquid crystal panel. It is characterized by.

The image display device may be configured by further bonding the λ / 4 plate when the circularly polarized light is applied.

The two polarizing glasses have a wireless receiver and an audio circuit, and are configured to receive an audio signal of a corresponding video transmitted from an image display device, decode it, and output the same to an earphone.

According to the present invention, a plurality of images can be simultaneously displayed on one screen so that a plurality of users can see only the images they want, so that each user can see the images he / she wants without the influence of other images to satisfy satisfaction. It can be effective.

2 is a structural diagram of an image display device of a self-luminescence method according to an embodiment of the present invention.
3 is a structural diagram of a backlight image display device according to an embodiment of the present invention;

Hereinafter, the present invention will be described in detail with reference to the drawings.

In the embodiments of the present invention, in order to clearly describe the technical spirit and essential characteristics of the present invention will be omitted a detailed description of the technology known to those skilled in the art.

1 is a schematic block diagram of an image display apparatus according to an exemplary embodiment of the present invention. As shown in FIG. 1, a display panel 110, a TN liquid crystal panel 120 bonded to a front surface of the display panel 110, and A display driver 130 for simultaneously displaying two images on the display panel 110 and a liquid crystal driver for converting polarization angles of the TN liquid crystal panel 120 corresponding to the images displayed on the display panel 110 ( 140, an audio transmitter 160 for transmitting an audio signal for each image displayed on the display panel 110, and a controller 150 for controlling each operation.

The pixel structure of the TN liquid crystal panel 120 disposed on the front of the display panel 110 has the same structure as that of the display panel 110.

That is, in the exemplary embodiment of the present invention, the polarization angle of the image displayed on the display panel 110 is zero by placing the TN liquid crystal panel 120 on the front of the display panel 110 to simultaneously display two different images. By adjusting the degree to 90 degrees, two images are simultaneously displayed on one screen, and the user selects and watches a desired image among two images displayed on the display panel 110.

In this case, the display driver 130 displays each image on the display panel 110 to display two images, and when the respective images are displayed, the liquid crystal driver 140 corresponds to the currently displayed image. The polarization angle of the TN liquid crystal panel 120 is converted.

The audio transmitter 160 wirelessly transmits audio corresponding to the image displayed on the display panel 130.

The above operation is performed by the controller 150.

In this case, the user may view a desired image by wearing polarized glasses (not shown). The polarized glasses (not shown) may have a unique polarization angle so that each image displayed on the display panel 110 may be viewed. It is manufactured to have.

That is, assuming that the polarization angles of the images displayed on the display panel 110 are 0 degrees and 90 degrees, respectively, the polarization angles of the respective polarizing glasses (not shown) for viewing the respective images are respectively 0 degrees and 90 degrees. .

The polarizing glasses (not shown) include a wireless receiver for receiving an audio signal transmitted from the audio transmitting unit 160 provided in the image display apparatus, and an audio for decoding the received audio signal and outputting the same to an earphone. The circuit is built.

Therefore, the user can wear a polarized glasses to watch the video and the voice corresponding to the video. In other words, assuming two users, different images can be viewed by wearing glasses having a polarization angle of 90 degrees.

In addition, according to an embodiment of the present invention, a horizontal interleaving method and a page flipping method may be used to display an image on the display panel 110.

The horizontal interleaving method displays different images on the odd lines 1, 3, 5... And the even lines 2, 4, 6... Of the display panel 110, and the display panel 110. In the TN liquid crystal panel 120 attached to the front surface, polarization angles of odd lines and even lines are controlled to be 90 degrees to each other.

In the page flipping method, two images are sequentially displayed on the entire line of the display panel 110, and all the lines of the TN liquid crystal panel 120 attached to the front of the display panel 110 are operated simultaneously. A wide angle is sequentially displayed at 90 degrees and 0 degrees, and two images are alternately displayed at odd and even frames.

On the other hand, in the embodiment of the present invention, the image display apparatus has a different structure when the display panel 110 is a self-luminous method and a backlight method.

First, when the display panel 110 is a backlight method, as shown in FIG. 2, the image display device according to the exemplary embodiment of the present invention includes a polarizing plate 211, a color liquid crystal display panel 212, a polarizing plate 213, and a TN. The liquid crystal panel 214 is sequentially bonded to each other.

When the display panel 110 is a self-luminous display, as shown in FIG. 3, the image display device includes a display panel 215, a polarizer 216, and a TN liquid crystal panel 217. It is constructed by joining sequentially.
