Embodiment Construction

[0034] like figure 1 , figure 2As shown, the suspended 360° light field three-dimensional display device based on a flat panel display in this embodiment includes a flat panel display array 1 , a first lens group array 2 , a second lens 3 , and a diffusion screen 4 .

[0035] Wherein, the flat panel display array 1 of this embodiment is composed of a plurality of flat panel displays as shown in FIG. 5 . The flat panel display is a Liquid Crystal Display (LCD), Plasma Display Panel (PDP), Cathode Ray Tube Display (CRT), Light Emitting Diode Display (LED) or Organic Light Emitting Display (OLED). In Figure 5(a) and Figure 5(b), the shaded area is the image display area, which is composed of sub-images corresponding to each viewpoint. As shown in the figure, the image display area is characterized by a circular distribution to provide 360 °Multi-view display. The sub-images displayed on the flat-panel display are arranged according to the interval of the viewpoint, and are ar...

Abstract

The invention discloses a suspended 360-degree optical field three-dimension display device and method based on a flat plane display. The device comprises a flat plane display array, a first lens group array, a second lens and a scattering screen which are arranged in sequence, wherein the flat plane display array is formed by splicing a plurality of flat plane displays; each flat plane display is used for displaying one part of various 360-degree sub-images around one circle of a three-dimension object, namely a sub-image sequence; various sub-images in the image sequences displayed by the flat plane display array, each first lens group in the first lens group arrays and various view points of an observation area correspond to one another. One observer can only see one sub-image at one view point. Through controlling the parameters such as the number of the sub-images displayed by the flat plane display array, an optical axis inclined angle of the overall system and the scattering angle of the scattering screen, the eyes of the observer in the observation area can be located in different view points, so that the two different sub-images displayed on the flat plane display array can be observed, and binocular parallax can be produced, thereby reaching the effect of watching three-dimension scenes.

Description

technical field [0001] The invention relates to a three-dimensional display device, in particular to a suspended 360° light field three-dimensional display device and a display method based on a flat display. Background technique [0002] Display technology is developing towards high-definition, three-dimensional panoramic display. The difference between three-dimensional display and traditional two-dimensional display is to bring visual depth perception to the viewer through various methods, so that it can naturally or unnaturally obtain the third-dimensional information in the picture. Many 3D display technologies at home and abroad can generally be divided into two types: holographic 3D display and non-holographic 3D display. Holographic three-dimensional display is known as the ideal three-dimensional display method in the future because it is a true three-dimensional information recording and display, but it requires a high-resolution spatial light modulator and an ult...
