3D stereo display technology

Abstract

The invention discloses a 3D stereo display technical scheme which is suitable for watching with naked eyes and can truly reappear an objective scene. Based on the technical scheme, dynamic focusing projection is carried out on pixels of a plane image through dynamic focusing light mixed lens matrix to form a light mixed real image, a formed image distance is equal to or is in direct proportion to an image distance of an image live scene, formed relative to a prefocus lens, all pixel real image distances are different and commonly form a stereo real image, the stereo real image is observed in an amplification way through a convex lens or is projected onto an imaging lens again to form an image to realize 3D stereo display technology and equipment for real scene reduction.

Description

Technical field [0001] The invention relates to a 3D stereoscopic display technical solution suitable for viewing with naked eyes, in particular to a 3D stereoscopic display technical solution for realizing restoration of a real scene by real-time modulation of the color and image distance of each pixel in a display matrix. Background technique [0002] At present, the commonly known stereoscopic display technologies are as follows: 1. Polarized light separation stereoscopic display technology; 2. Field scanning stereoscopic display technology; 3. Left and right shift stereoscopic display technology; 4. Red and green separation stereoscopic display technology; 5. Holographic three-dimensional display technology; 6. Grid offset three-dimensional display technology; 7. Prism offset three-dimensional display technology. Among them, 1, 2, 3, and 4 all need to wear glasses, and 5, 6, and 7 do not need to wear glasses. The above various implementation technologies will be compare...

AI Technical Summary

Problems solved by technology

[0004] The latter three technologies do not require wearing glasses, and the effect of 5 is the best, but the structure is extremely complex, the cost of implementation is huge, and the amount of data is too large to be practical

6 It has been applied to three-dimensional liquid crystal displays, and the effect is good, but the viewing angle is narrow, and the three-dimensional effect is limited to a narrow range of distance and angle, and the number of viewers and positions are subject to many restrictions

7 It is mostly used for toys and undemanding still pictures, and the image quality is poor

[0005] The three-dimensional display method described in the above-listed technologies has the problem that glasses must be worn or the effect is poor or difficult to realize, and cannot meet the needs of people's practical applications.
