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...

Embodiment Construction

[0045] An embodiment of the present invention: a 3D stereoscopic display using a constant-voltage uniform electric field to drive a lens with modulated charges.

[0046] Using integrated circuit manufacturing technology or other micro-electromechanical processing technology, the transparent electrode layer, spring, focusing lens and driving circuit are made on a liquid crystal display corresponding to the area of ​​each imaging unit to form a focusing lens matrix, which completely corresponds to each liquid crystal. The imaging unit has a conductive film on the surface of the focusing lens, and the conductive film is connected to the storage and drive circuits. Install a cylindrical lens matrix at a certain distance above the focusing lens matrix. The distance can be equal to or less than the focal length of the lens. The cross-sectional area of ​​each cylindrical lens is equal to the area of ​​a liquid crystal display unit. The height of the cylindrical lens matrix is ​​determ...
