Abstract

The invention discloses a projection display system, a projection module and 3D glasses, which are used for solving the technical problem of poor display projection effect in the prior art. The projection display system comprises a projection module and 3D glasses used in cooperation with the projection module. The projection module comprises an input light source and a display unit. The input light source comprises at least one group of light sources; each group of light sources at least outputs light with at least one wavelength in three wave bands of R, G and B; the display unit receives light output by the light source and then modulates and emits image light of two parallax images at the same time, the wave band combination of the image light of the two parallax images at least comprises an R wave band, a G wave band and a B wave band, and then the 3D glasses receive the light of the two parallax images from the projection module and are matched with the projection module to achieve 3D display. The left glasses lens and the right glasses lens in the 3D glasses respectively receive two parallax images to form 3D display, so that human eyes receive at least three colors of RGB,the colors of 3D contents watched by a user are enriched, and the projection display effect is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a projection display system, a projection module and 3D glasses. Background technique [0002] With the development of display technology, more and more 3D (3Dimensions, three-dimensional) theaters have entered people's lives. 3D display technology has the characteristics of prominent main body, strong three-dimensional effect and realistic effect. The various objects in the film seem to rush towards the face, as if they are in the film, and the sense of substitution is very strong. [0003] Red and blue 3D movie display technology uses left and right projectors to project parallax images from two different viewing angles in red and blue colors. Users wear achromatic 3D glasses (usually red on the left and blue on the right). Red light passes through, and blue lenses pass through blue light. Therefore, the user sees a red picture with his left eye (shooting angle 1), and a blue...
