Abstract
The utility model relates to an L-type dual-projector projection system, which comprises a first projector for projecting a first image, and a second projector for projecting a second image. The first emergent light path of the first projector is vertical to the second emergent light path of the second projector. The projection system further comprises a light path adjusting unit arranged on the second emergent light path. The light path adjusting unit is used for changing the second emergent light path so as to coincide a picture of the second image formed on a screen with a picture of the first image formed on the screen. Due to the adoption of the L-type dual-projector projection mode, the problem that the two projection pictures of two projectors arranged in an up-down manner or in a left-right manner cannot be highly coincided with each other due to the poor projection brightness of the projectors on a huge screen is solved. Meanwhile, both the realistic effect of movie pictures and the visual viewing comfort level of movie viewers are improved, especially for the projection of 3D movies.
