Embodiment Construction

[0072] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.

[0073] refer to figure 1 , figure 2 A naked-eye 3D projection system includes a projection system 2, a projection screen, and a microprocessor system connected to the projection system 2, and a naked-eye 3D projection screen 1 is used for the projection screen. The naked-eye 3D projection screen 1 includes at least two groups of display arrays, namely a first display array and a second display array. The first display array includes at least 100 first strip display regions 41 arranged vertically. The second display array includes at least 100 second strip display areas 42 arranged vertically. The first striped display areas 41 of the first display array and the second striped display areas 42 of the second display array are arranged alternately. ...

Abstract

The invention discloses a naked eye 3D (Three-Dimension) projection system, and relates to the field of display, in particular to the field of 3D display. The projection system comprises a projection system part, a projection screen, and a micro-processor system connected with the projection system part, wherein the projection screen adopts a naked eye 3D projection screen. The naked eye 3D projection screen comprises at least two display arrays, namely a first display array and a second display array. Emission directions of light of different pictures displayed on the first display array and the second display array are adjusted by a light direction modulation mechanism, so that the light of the different pictures is irradiated to left eyes and right eyes of audience. And an image with a 3D effect in front-back, up-down, left-right and far-near directions is formed by utilizing a fact that a left eye and a right human eye receive different pictures respectively and then a human brain performs image information overlapping and regeneration.. With the adoption of the design, the projection system with a naked eye 3D display effect can be achieved.

Description

technical field [0001] The invention relates to the field of display, in particular to the field of stereoscopic display. Background technique [0002] The "D" in "3D" is the first letter of the English word Dimension. 3D refers to three-dimensional space. Compared with ordinary 2D picture display, 3D technology can make the picture three-dimensional and realistic, and the image is no longer limited to the screen plane, as if it can go out of the screen, so that the audience has an immersive feeling. [0003] Although there are many types of 3D display technologies, the basic principles are similar, that is, the left and right sides of the human eye are used to receive different pictures, and then the brain superimposes and regenerates the image information to form a front-back, up-down, left-right display. , far-near and other stereoscopic effects. [0004] In glasses-based 3D technology, we can subdivide three main types: chromatic aberration, polarized light and active...
