Description

Video display device {IMAGE DISPLAY APPARATUS}

The present invention relates to an image display device, and more specifically, both sides opposite to each other by reflecting different images projected from a pair of display units through a pair of half mirrors (or transflective mirrors). It relates to an image display device that allows different users to view different floating images (or virtual images).

In general, with the development of information communication technology and display technology, a demand for a more realistic image such as a 3D stereoscopic image is increasing, and a demand for an apparatus for displaying a stereoscopic image will increase rapidly. Various stereoscopic image technologies have been proposed to meet these demands, and there are technologies using virtual reality and technologies for realizing stereoscopic images using holography technology.

The technology using the virtual reality is a typical method in which a user wears a goggle type device and views a virtual image using computer graphics. However, this method has a disadvantage that the user cannot conveniently use a separate device in order to view the virtual image.

Another method is to implement a hologram image in space using holography technology. The hologram is made by recording the interference pattern between the reference light and the object light by injecting the light reflected from the object to be recorded with the reference light and information onto the recording medium, that is, the object light.

Since Dennis Garbor first invented the hologram, the most common methods to date have been the two beam transmission hologram developed by E, Leith, etc., and the one beam developed by Denisyuk, etc. reflection hologram, and Edge-lit hologram developed by N. Phillips et al.

The transmissive hologram causes the reference light and the object light to enter the recording medium in the same direction during recording, and during reproduction, the reference light transmits the hologram recorded on the recording medium so that the hologram is reproduced in the opposite direction to the reference light.

In the reflective hologram, the reference light and the object light are incident in the opposite direction to the recording medium during recording, and the reference light reflects the hologram during reproduction so that the hologram is reproduced in the same direction as the reference light.

In order to reproduce the conventional hologram, there are still many technical problems, and recently, a technique of reflecting and synthesizing an image using a reflective film so that a viewer can recognize it as a hologram has been proposed.

However, the hologram of this method can observe only a stereoscopic image as much as the size of the manufactured hologram. Therefore, in order to observe a large stereoscopic image, the size of the hologram must be made large. Therefore, the size of the stereoscopic image that can be observed in proportion to the size of the hologram was also limited.

In addition, there is a problem in that there is a limitation in realizing a realistic stereoscopic image only by reflection synthesis of an image using a reflective film.

On the other hand, in recent years, there is a need for a video display device that can be used for various purposes, such as education, promotion, counseling, promotional events, and exhibitions, by using a variety of functions, rather than a device that displays only a simple image.
