Embodiment Construction

[0038] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not used to limit the present invention.

[0039] see figure 1 , figure 1 It is a working principle diagram of a two-machine high-light-efficiency stereoscopic projection system provided by an embodiment of the present invention. Such as figure 1 As shown, the two-machine high-light-efficiency stereoscopic projection system includes a first projector 101, a polarizing subsystem attached to the first projector (not shown in the figure), a second projector 102, and a polarizing subsystem attached to the second projector (shown in the figure). Not marked in ), the first projector auxiliary polarizati...

Abstract

The invention provides a double-machine high-luminous efficiency stereo projection system. The projection system comprises a first projector, a first projector accessory polarization subsystem, a second projector and a second projector accessory polarization subsystem. The first projector accessory polarization subsystem is arranged between the first projector and a screen. The second projector accessory polarization subsystem is arranged between the second projector and the screen. An angle is formed between the first projector and the first projector accessory polarization subsystem, and the second projector and the second projector accessory polarization subsystem, thereby projecting images on the screen. Thus, left eye image light beams projected to the screen by the first projector through the first projector accessory polarization subsystem are P linearly polarized light. Right eye image light beams projected to the screen by the second projector through the second projector accessory polarization subsystem are S linearly polarized light, so audiences can see stereo images after wearing linear polarization glasses.

Description

technical field [0001] The invention relates to the technical field of 3D projection display, in particular to a two-machine high-light-efficiency stereoscopic projection system. Background technique [0002] The existing two-machine three-dimensional projection playback system is realized by using the following principles: use the first projector to play the content of the left eye image, place a light polarizer on the light exit surface of the first projector, and use the second projector to play For the content of the right eye screen, another light polarizer is placed on the light exit surface of the second projector. The absorption optical axes of the two light polarizers form an angle of 90 degrees. The viewer wears polarized glasses made of an analyzer. The left eye only sees the picture content of the left eye, and the right eye only sees the picture content of the right eye, thus presenting a 3D display effect. [0003] The purpose of the light polarizers placed on...
