The true three-dimensional display is a three-dimensional display mode with a good effect at present, and a displayed three-dimensional image is an objective entity and is very visual. The person viewing the display is allowed to walk around and view the object being displayed from different positions. The viewer can not feel uncomfortable during watching, and any auxiliary watching equipment is not required to be equipped, so that real naked eye three-dimensional display is realized.
Although true three-dimensional displays have many advantages, many true three-dimensional displays have complex rotating screens or similar devices, and the rotating motion causes problems of mechanical vibration, noise, and loss.
Therefore, there is a need to provide a true three-dimensional display that does not require screen rotation.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems of mechanical vibration, noise, loss and the like caused by screen rotation in the prior art, the utility model provides a true three-dimensional display which uses a flat panel display to project light into a stereoscopic diffuser to form a true three-dimensional image.
The utility model provides a technical scheme that its technical problem adopted is: a true three-dimensional display, comprising: a flat panel display; a stereoscopic diffuser; a controllable focal length liquid lens array. A flat panel display including a two-dimensional array of pixels individually operable to emit light; a stereoscopic diffuser positioned proximate to the flat panel display and configured as a display volume; the controllable focal length liquid lens array is positioned between the flat panel display and the stereoscopic diffuser, is spaced from the flat panel display by a distance of 2R, converges light emitted by all pixels of the flat panel display to a certain plane, and controls to rapidly change the focal length f of the liquid lens array so as to image the plane at different heights.
The flat panel display is an Organic Light Emitting Diode (OLED) display.
The aforementioned stereoscopes comprise a transparent container filled with aerosol particles.
The flat panel display and the controllable focus liquid lens array cooperate to focus light passing through the plurality of controllable focus liquid lenses simultaneously onto a plane of the stereoscopic diffuser.
The utility model has the advantages that true three-dimensional display uses flat panel display to project light into stereoscopic diffuser to form true three-dimensional image, very directly perceived. The screen does not need to rotate, mechanical vibration and noise caused by rotation motion are eliminated, and better watching experience is brought to a viewer.

Detailed Description
In order to explain the present invention more clearly, the present invention will be further explained with reference to practical examples and drawings. Similar parts in the figures are denoted by the same reference numerals.
As shown in fig. 1, a true three-dimensional display 10 for displaying a three-dimensional image is a graphic display device that forms a true three-dimensional image. The person 12 views a display image 14, such as a cube image as shown, from the true three-dimensional display 10. The person 12 may move around the volumetric three-dimensional display 10 and view the image 14 from different locations. The cube image is as it actually exists in the true three-dimensional display 10.
As shown in fig. 2, a cross-sectional side view of a true three-dimensional display 10 including a flat panel display 16. Typically, the flat panel display 16 is comprised of a two-dimensional array of pixels. As shown in fig. 2, are pixels 18a, 18b, and 18c in a one-dimensional array. It should be appreciated that in general, each pixel 18a, 18b, 18c is individually operable to selectively emit light such that an image from the flat panel display 16 may be rendered by the true three-dimensional display 10. It should be further understood that each pixel may include a red OLED, a green OLED, and a blue OLED, such that light emitted by any particular pixel may appear in any color. As used in this example, the flat panel display 16 is an Organic Light Emitting Diode (OLED) display. The size and resolution of the display is selected according to the desired performance of the true three-dimensional display 10.
True three-dimensional display 10 also includes a stereoscopic diffuser 20 positioned adjacent flat panel display 16 and configured to display volume 22. As used in this example, a stereoscope is an object that scatters light projected onto itself. The extent to which a point or plane within the stereoscopic diffuser 20 is illuminated depends on how much light is present at the point or plane. The stereoscope 20 includes a transparent container 24 formed of glass, and the transparent container 24 is filled with aerosol particles.
True three-dimensional display 10 also includes a controllable focal length liquid lens array 26 interposed between flat panel display 16 and stereoscopic diffuser 20. In general, each controllable focus liquid lens 28a, 28b, 28c is individually operable to direct light 30a, 30b, 30c emitted by one or more pixels toward a location 32a of a plane within display 22 such that location 32a is selectively illuminated brighter than other locations 32b, 32c within display 22.
It is further shown in fig. 3 that the light from each pixel 18a-18i is directed by the controllable focal length liquid lens array 26 and that the focal length f of the lens is rapidly changed so that specific locations of the different elevation planes (e.g., locations 32a, 32d, 32 e) are selectively illuminated and combined so that images are imaged at the different elevation planes of the display 22.
Thus, by using the stereoscopic diffuser 20 to provide an illuminable position, the light from the flat panel display 16 is directed to that plane using the controllable focal length liquid lens array 26, through the rapid change in focal length, to image at a different plane. A true three-dimensional display is realized in which a viewer directly sees a true three-dimensional image due to the persistence of vision effect.
The above embodiments are only used for explaining the present invention, and not for limiting the protection of the present invention, and any insubstantial changes made on the basis of the essential schemes of the present invention should fall within the protection scope of the present invention.
