Laser and DLP combined spectrum separated three-dimensional projection device

Abstract

The invention relates to a laser and DLP combined spectrum separated three-dimensional projection device. The laser and DLP combined spectrum separated three-dimensional projection device comprises alaser projector, a DLP projector, a spectrum separated left-path lens and a spectrum separated right-path lens, wherein the spectrum separated left-path lens is arranged at a front end of the laser projector, and the spectrum separated right-path lens is arranged at a front end of the DLP projector. Compared with the prior art, the laser and DLP combined spectrum separated three-dimensional projection device has the advantages of good film effect, low implementation cost and the like.

Description

technical field [0001] The invention relates to a stereoscopic projection device, in particular to a laser and DLP combined spectrum separation stereoscopic projection device. Background technique [0002] The current stereoscopic projection method in the market is to use two DLP projectors as a combination. The two lenses are respectively equipped with polarized lenses, and polarized glasses are worn so that the left eye can only see the left image, and the right eye can only see the right image. , and the polarizing lens in front of the projector lens is equivalent to a polarizer. After the light emitted from the projector passes through the polarizing lens, it becomes polarized light. The polarization directions of the polarizing plates in front of the left and right projectors are perpendicular to each other, resulting in The polarization directions of the two beams of polarized light are also perpendicular to each other. The two beams of polarized light are projected on...

[0002] The current stereoscopic projection method in the market is to use two DLP projectors as a combination. The two lenses are respectively equipped with polarized lenses, and polarized glasses are worn so that the left eye can only see the left image, and the right eye can only see the right image. , and the polarizing lens in front of the projector lens is equivalent to a polarizer. After the light emitted from the projector passes through the polarizing lens, it becomes polarized light. The polarization directions of the polarizing plates in front of the left and right projectors are perpendicular to each other, resulting in The polarization directions of the two beams of polarized light are also perpendicular to each other. The two beams of polarized light are projected on the screen and then reflected to the audience. Seeing the picture on the left side, the right eye can only see the picture on the right side, so you can see the three-dimensional picture. However, this combined projection method has two disadvantages. First, due to the use of polarized lenses, the brightness loss of the picture is obvious , affecting the viewing experience; 2. Due to the use of 2 DLPs, the cost of bulb replacement and maintenance is high
