The research and commercialization of Korea is focused on. In particular, the liquid crystal display (LCD) of the flat panel display device is an image representing the image using the optical anisotropy of the liquid crystal, is excellent in resolution, color display and image quality, and is actively applied to notebooks or desktop monitors have.

The liquid crystal display is largely composed of a color filter substrate and an array substrate, and a liquid crystal layer formed between the color filter substrate and the array substrate.

As shown in the figure, the liquid crystal display device is largely a liquid crystal layer (liquid crystal layer) formed between the color filter substrate 5 and the array substrate 10 and the color filter substrate 5 and the array substrate 10 ( 30).

The color filter substrate 5 includes a color filter C composed of a plurality of sub-color filters 7 for implementing colors of red (R), green (G), and blue (B); A black matrix 6 that separates the sub-color filters 7 and blocks light passing through the liquid crystal layer 30, and a transparent common electrode that applies a voltage to the liquid crystal layer 30. 8)

In addition, the array substrate 10 may be arranged vertically and horizontally to define a plurality of gate lines 16 and data lines 17 and a plurality of gate lines 16 and data lines 17 that define a plurality of pixel regions P. The thin film transistor T, which is a switching element formed in the cross region, and the pixel electrode 18 formed on the pixel region P, are formed.

The color filter substrate 5 and the array substrate 10 configured as described above are joined to face each other by sealants (not shown) formed on the outer side of the image display area to form a liquid crystal display panel. The bonding of the 5 and the array substrate 10 is made through a bonding key (not shown) formed on the color filter substrate 5 or the array substrate 10.

The liquid crystal display device or the plasma display panel (PDP) has been designed to be viewed simultaneously by multiple users as a two-dimensional display device. The display characteristics of such a display device are made such that a viewer can view the same high quality image from different angles with respect to the display device.

However, there are many cases where it is required for each user to see different information from the same display device. For example, in a car the driver may want to see satellite navigation data while the passenger may want to watch a movie. As another example, each player in a two or more computer game wants to see the game from his own perspective.

These conflicting requirements can be met by providing two separate displays, but this will take up excessive space and increase costs.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a multi-view display that displays two or more images so that each image can be viewed in a different direction.

Another object of the present invention is to provide a multi-view display in which image quality deterioration and luminance deterioration occur due to undesired reflection due to the use of parallax barriers.

Another object of the present invention is to provide a multi-view display that controls the front and side brightness by differently designing the opening area transmitted to the front or side according to the purpose of use.

Other objects and features of the present invention will be described in the configuration and claims of the invention described below.

Hereinafter, exemplary embodiments of a multi-view display according to the present invention will be described in detail with reference to the accompanying drawings.

2 is an exemplary diagram schematically showing a multi-view display in which each image can be viewed in three different directions.

3 is an exemplary diagram schematically illustrating the concept of a multi-view display.

As shown in FIG. 2, the multi-view display 10 is a technology for displaying two or three different images on one display panel in a way of controlling the viewing angle. (C) is a viewing angle controlled display capable of displaying different images.

The drawing shows a triple view display 10 for viewing different images when the panel is viewed from the front (A), when viewed from the left 50-degree tilt (B), and when viewed from the right 50-degree tilt (C). For example, it is shown.

Since the triple view display 10 simultaneously displays three types of images, the number of pixels in each direction is one third of the total number of pixels, and a dual view display capable of displaying different images in two different left and right directions. This can be achieved by improving the technology and parallax barrier technology.

As described above, the multi-view display is a display capable of simultaneously providing different images according to the viewing direction using a single liquid crystal display panel. As shown in FIG. 3, the multi-view display is incident from the backlight using the parallax barrier 20. The light is divided into three optical paths of the center (C), left (L), and right (R) pixels 7 to display three different images simultaneously.

Accordingly, it is possible to watch TV in the center (C), and to play games or surf the Internet on the left (L) or right (R).

The basis of this technology is a 3D liquid crystal display technology, and the 3D liquid crystal display technology installs a slit partially blocking the light on the front of a general liquid crystal display panel so that the right eye and the left eye can show different images. This is a technology that makes one image appear three-dimensional. At this time, the slit to be installed corresponds to the parallax barrier.

Here, although the parallax barrier applied in the 3D liquid crystal display device is used to realize the dual view or triple view display, the position of the parallax barrier is closer to the liquid crystal display panel so that the left and right images can be separated. By widening it is implemented.

As described above, in the 3D liquid crystal display, the image is separated at an angle of about 6 degrees with respect to the left and right eyes using a parallax barrier, but in the multi-view display, the separation angle is widened by 40 degrees or more, and the pixel arrangement is optimized. Multi-view can be realized.

As application fields of the multi-view display, a car navigation device capable of multi-screen display, an advertisement display, and the like can be considered. For example, in the case of a car navigation application, a navigation screen is provided to a driver to display road information to a destination, a passenger's companion is displayed to make a tourist information searchable, and a back seat enjoys a DVD movie image. Application is possible. In addition, in the advertisement display field, three different pieces of information may be displayed according to a moving direction of a pedestrian.
