Description

{AUTOSTEREOSCOPIC 3D DISPLAY APPARATUS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a 3D display device, and more particularly, to a parallax barrier 3D glassesless display device capable of realizing an augmented reality.

Generally, the distance between the two eyes is called interocular, and the left eye and right eye observe different images slightly due to eye movements when looking at an object. This is called binocular disparity, and a person feels stereoscopic because of this binocular disparity.

Therefore, when the two eyes of the right and left eyes see different two-dimensional images, and the two images are transmitted to the brain through the retina, the brain fuses them to reproduce the depth sense and real feeling of the original three-dimensional image. This is commonly referred to as steerography.

Most techniques for realizing stereoscopic images use binocular disparity. These techniques present a left-eye image (left eye image) in the left eye and a parallax in both eyes by presenting the right eye image (right eye image) in the right eye.

The stereoscopic method and the autostereoscopic method are used for separating the left eye image and the right eye image from each other in the left eye and the right eye respectively. There are a parallax barrier method and a lenticular method for the non- Method.

According to the parallax barrier method, a barrier filter is disposed in front of the image panel, and the left eye sees the left eye image through the barrier filter and the right eye sees the right eye image.

Generally, a parallax barrier system is composed of a display panel and a barrier disposed at a position spaced apart from the panel by a certain distance, and the barrier comprises a portion through which light from each pixel of the display panel is transmitted and a shielding film which is shielded from the beam. The shielding film is arranged such that light from the pixels for the left eye is incident only on the left eye and light from the right eye pixels is incident on the right eye only.

That is, in the parallax barrier system, the pixels of the display panel are arranged in the left eye pixel and the right eye pixel of the R, G, and B pixel units, and the left eye pixel and the right eye pixel A stereoscopic image is reproduced by providing a shielding film for each part corresponding to the left eye image and the right eye image only in the left eye and the right eye image only in the right eye.

Therefore, in the conventional parallax barrier system, there is a problem that the parallax barrier system can not be used for a service purpose such as an augmented reality in which an object behind the display panel should be seen, because an actual object behind the display panel is not seen.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a parallax barrier type non- And a 3D display device.

According to an aspect of the present invention, there is provided a spectacle-free 3D display device including a display screen in which left-eye pixels and right-eye pixels are alternately arranged; And a barrier disposed at a position separated from the display screen by a predetermined distance so that a left eye image is displayed on the left eye of the viewer and a right eye image is displayed on the right eye of the viewer, Region and a left eye emitting region, and the right eye pixel includes a right eye transparent region and a right eye light emitting region.

The display screen is implemented by any one of a TFT-LCD panel (Thin Film Transistor-Liquid Crystal Display panel), an OLED (Organic Light Emitting Diodes) panel, and a holographic screen in an RGB (Red Green Blue)

When the display screen is implemented by the TFT-LCD panel or the OLED panel, the TFT-LCD panel or an object in which the 3D virtual object displayed by the OLED panel and the object located on the back of the display screen are combined, Is displayed.

The 3D virtual object from the projection device located on the rear side of the display screen and the object placed on the rear side of the display screen are combined with each other when the display screen is embodied as the holographic screen .

The barrier is realized by a TN-LCD (Twisted Nematic-LCD) panel or a STN-LCD (Super TN-LCD).

Wherein the left transparent region and the right transparent region are arranged so that a rear-positioned object of the display screen is displayed to a viewer.

Wherein the left transparent region is disposed such that the projected object is visible in the left eye, and the right transparent region is disposed so that the object appears in the right eye.

Wherein the barrier comprises a transmissive region through which light from each pixel of the display screen is transmitted and a blocking region in which light is blocked, wherein the blocking region is made such that light from the left eye pixel enters the left eye only, So that the light from the light source enters the right eye only.

The non-spectacle 3D display device according to the present invention includes a display screen having a predetermined transparent area formed for each pixel, so that an actual object can be observed with the naked eye through the transparent area.

Since an actual object can be observed with the naked eye, 3D augmented reality can be realized like a see-through display device using a parallax barrier type non-spectacle 3D display device such as Google glass and MS hololens.

For example, in manufacturing the display screen 110, the light emitting regions 111b and 113b may be formed by printing a material such as a conventional holographic screen (e.g., a projector rear projection screen, a transparent rear projection film, or a holographic film) And the transparent regions 111a and 113a are formed by printing with a transparent material so that light of a project is not scattered.

The barrier 130 is disposed at a position separated from the display screen 110 by a predetermined distance so that a left eye image is displayed on the left eye of the viewer and a right eye image is displayed on the right eye of the viewer.

For example, the barrier 130 may be a parallax barrier, such as a TN-LCD (Twisted Nematic-LCD) panel or a STN-LCD (Super TN-LCD).

The barrier 130 includes a transmissive region 131 through which light from each pixel of the display screen 110 is transmitted and a blocking region 133 through which light is blocked. The light from the pixel 111 is incident only on the left eye and the light from the right eye pixel 113 is incident on the right eye only.
