Stereoscopic image display device

The present invention relates to a stereoscopic image display technology, and more particularly to a stereoscopic image display device capable of displaying a stereoscopic real image in a space and allowing the naked view to be naked.

According to the human vision, the human vision is based on stereoscopic viewing, that is, the images seen by the two eyes overlap in the brain to form vision; in order to achieve the purpose of stereoscopic viewing, the traditional practice is to watch the user wear special design glasses. Stereoscopic stereoscopic display technology and auto-stereoscopic stereoscopic display technology for naked eye viewing, or by arranging a barrier between the display panel and the human eye for viewing by the human eye A stereoscopic display of a stereoscopic image.

In addition to the above-mentioned two devices for achieving stereoscopic viewing, in addition to the inability to achieve the view of the ring landscape, it is even necessary to obtain a stereoscopic viewing effect through a special design eye or a grating mirror view; therefore, another conventional stereoscopic image generating device appears in the room. a hollow cylindrical inner casing is disposed in a table having a proper accommodating space; a first lens and a second lens are further disposed at an appropriate position in the inner casing, and the first lens is located on a central axis of the inner casing, There is an opening below the first lens; a projection lens below the central axis of the inner casing, and a lens cover above the inner casing; and a drive motor disposed at the side of the inner casing, and the inner casing and the drive motor are coupled by a belt .

It mainly projects the planar image upward by the projection lens, and the image beam is worn. After passing through the opening, the first lens is reflected to the second lens, and the second lens is reflected to the lens. Finally, the image beam passes through the lens at an angle to the table top. At the same time, the driving motor drives the inner casing to rotate, thereby enabling the image beam to Projected around three hundred and sixty degrees.

As for the projection image, the image projected by the projection lens is a different image taken at various angles. When the inner casing rotates, the projection lens also sequentially projects the angle images. When the person is around the table, the image is projected to the double. In the eye, the left eye and the right eye respectively receive two frames of images adjacent to each other, and a virtual stereoscopic image is generated by the brain fusion operation. However, the above conventional stereoscopic image display technology must still see an approximate stereoscopic image when the line of sight is at a height position of the image projection direction.

In addition, there is another method of projecting the image toward the virtual screen to generate a stereoscopic image for naked viewing. This stereoscopic viewing technique requires at least one pair of limiting walls to limit the forced flow range of the plurality of micro-particles. And the virtual screen is formed, so that even if the current image technology can use several image files to be simultaneously projected from different angles, the at least one pair of restricted walls will constitute a projection dead angle, and the image of the scene cannot be generated, and smoke and dry ice must be used. Opaque particles such as water vapor or water mist act as a medium (virtual screen) for image formation, thereby reducing the realism of the image and increasing the number of conditions for use.
