The stereoscopic image display is characterized in that an image storage unit, an image play unit, a liquid crystal panel, a projection lamp, a back projection film and a group of driving components are at least integrated in a rack, wherein a two-dimensional (2D) image file stored in the image storage unit is played by the play unit and is displayed on the liquid crystal panel; then an image of the liquid crystal panel faces to the back projection film configured at 45 degrees by the projection lamp; under the action that the driving components drive the back projection film to rotate by 360 degrees continuously, a viewer can view the image displayed on the back projection film from any angle in 360 degrees; and under the action of image superimposing, the viewer can view the stereoscopic three-dimensional (3D) image effect like a real object.

Description

Dimensional image display

Technical field

The relevant a kind of video display of the utility model, refer to especially a kind of can be from arbitrarily angled the viewing and admiring of 360 degree, and then build dimensional image display as stereoscopic three-dimensional (3D) image effect as the material object.

Background technology

Press, (Cathode Ray Tube has been since the black and white television set invention of mode of operation CRT), and display technique is just with the continuous evolution of very fast speed with cathode-ray tube (CRT) since first; According to prior art, cathode ray tube (CRT) TV, personal computer (PC) display, liquid crystal (LCD) TV and electricity slurry (PDP) TV are mainly laid a foundation in two-dimentional imaging technique.Yet, human vision be see based on solid and look, promptly be that being seen images are overlapping to form vision in brain respectively with two eyes.

In order to reach the three-dimensional purpose of looking of seeing, but at present known technology includes: wear the hyperphoria with fixed eyeballs mirror (Stereoscopic) that the particular design glasses watch bore hole formula (Auto-stereoscopic) stereo display technique that stereo display technique and bore hole are watched by the user, and by grating (barrier) is disposed between display panel and the human eye, so that human eye is watched the three-dimensional display of a stereopsis.

Because hyperphoria with fixed eyeballs mirror stereo display technique is not good because of its convenience and comfortableness, and is replaced by the three-dimensional display of bore hole formula stereo display technique gradually.The similar three-dimensional display of commonly using comprises a display panels, liquid crystal light valve (LC shutter), and backlight basically; Wherein, display panels has the plural pixel cell that shows the left-eye images data, and shows the plural pixel cell of right-eye image data, and pixel cell and pixel cell dispose in the mode of being spaced alternately.

Moreover, the video camera that left eye and right-eye image data for example can utilize two levels to settle side by side, the commissarial left side of difference, right eye is shot two picture makings synchronously and is gone out, by the parallax light spare of liquid crystal light valve as generation right and left eyes vision separating effect, when liquid crystal light valve is opening (ON), applying voltage can change the assortment state of part liquid crystal molecule and form plural light tight block, be misplaced the parallax effect of generation by the pixel cell of light tight block and display panels, when by the light that sends backlight by liquid crystal light valve and display panels after, the left eye that can make the observer only can be seen the left-eye images data and right eye only can be seen the right-eye image data, and produces stereoscopic three-dimensional (3D) image display effect.

Yet, on take off and commonly use three-dimensional display, not only one-piece construction is tending towards complicated, increases material, processing cost relatively; Especially, only can display panels over against side picture view and admire stereoscopic three-dimensional (3D) image, therefore can't view and admire stereoscopic three-dimensional (3D) image that the display panels front is presented in the position at the display panels back side, can't build as stereoscopic three-dimensional (3D) image effect as the material object.
