Problems solved by technology

At present, the viewing angle is limited by setting curtains around the screen or guardrails around the device
Therefore, people can only watch it from a certain viewing distance and within a limited viewing angle, otherwise the top screen will be exposed

Abstract

The invention discloses a floated quasi-three dimensional display device sheltered by a display screen, comprising a polarized display, a pyramid polarized rotating mirror, a first polaroid, a second polaroid, a third polaroid, a fourth polaroid and a base. The center of the base is provided with the pyramid polarized rotating mirror above which the polarized display is arranged; the pyramid polarized rotating mirror is a square pyramid or a square prismaid, each of the four lateral sides of the square pyramid or the square prismaid has an included angles of 45 degrees with the bottom surface; and the periphery of the bottom surface is vertically provided with the first polaroid, the second polaroid, the third polaroid and the fourth polaroid. The invention has simple structure, can be observed by encircling of 360 degrees and by multiple angles in a close distance, and can realize large-area quasi-three dimensional display in tens of square meters and miniature portable three-dimensional display.

Description

technical field [0001] The invention relates to a three-dimensional display device, in particular to a suspended quasi-three-dimensional display device covered by a display screen. Background technique [0002] The difference between three-dimensional display and 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. For the viewer, there is a difference between true three-dimensional and false three-dimensional (or quasi-three-dimensional). The development of 3D display technology has produced a large number of achievements today, which can be roughly divided into holographic 3D display, volumetric 3D display, and stereoscopic 3D display. Holographic technology can produce very realistic spatial effects, but it requires high-resolution spatial light modulators and ultra-high-speed data processing systems in terms of dynamic display.
