Embodiment Construction

[0031] Various details involved in the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be pointed out that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.

[0032] 1. The main body of the true three-dimensional imaging display

[0033] The structure of the true three-dimensional stereo imaging display is as follows: Figure 1a as well as Figure 1b shown. The true three-dimensional imaging display screen is made of translucent high-strength photosensitive resin material, which is directly processed and manufactured by rapid prototyping (RP). On the basis of ensuring the strength of the entire true three-dimensional imaging display screen, it remains stable under rapid rotation and reduces wear and tear. The true three-dimensional imaging display screen is composed of a first screen 1, a second screen...

Abstract

The invention discloses a true three-dimensional imaging display screen consisting of a first screen, a second screen, an I-shaped beam and a connecting shaft sleeve, wherein upper end lines, lower end lines and single-lead spiral surfaces are respectively arranged on the first screen and the second screen; inner and outer spiral lines are arranged on the single-lead spiral surfaces; the I-shaped beam consists of an upper edge part, a lower edge part and an intermediate shaft; the intermediate shaft comprises an intermediate shaft top surface and an intermediate shaft bottom surface; first upper edges and second upper edges are respectively arranged at the upper edge parts and the lower edge parts; the upper edge part and the lower edge part of the I-shaped beam are symmetrical to the intermediate shaft and vertical to the center line of the intermediate shaft; the upper edge part is fixedly connected with the top surface of the intermediate shaft; the connecting shaft sleeve is rotatably connected with the bottom of the intermediate shaft; the single-lead spiral surfaces are fixedly arranged on two semi-circumferences of the intermediate shaft along the length of the intermediate shaft; the circumference of the intermediate shaft is respectively and fixedly connected with the first inner spiral lines and the second inner spiral lines to form a dual-spiral curved screen; the parts between the first screen and the second screen are symmetrical relative to the center of the intermediate shaft; the first upper end lines and the first lower end lines are respectively and fixedly connected with the first upper edges and the second lower edges; and the second upper end lines and the second lower end lines are respectively and fixedly connected with the second upper edges and the first lower edges.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic display and relates to a display screen used for true three-dimensional stereoscopic imaging. Background technique [0002] The use of rotating spiral surface as a display screen to generate true 3D images has been implemented abroad. Researchers from Texas Instruments have conducted extensive research on the technology of laser scanning rotating surfaces to generate true 3D images. The combination of spiral screen and laser scanning technology Tried on three-dimensional display; German D.Bahr et al. used three-color lasers to scan a fast-rotating single-helical curved display to form a color true three-dimensional image. The advantage of this type of true three-dimensional display method is that a single-lead or double-sided spiral-shaped curved surface with a support structure is used as the display surface, and the three-dimensional space where the visible light point is located is fully u...
