A laser projector includes a laser source, a first dichroic mirror, a wavelength conversion module, a second dichroic mirror, a first, a second and a third light valves and a beam combiner. The laser source is for providing a blue beam including a first portion and a second portion. The first dichroic mirror is for receiving and allowing the blue beam to penetrate. The wavelength conversion module is for receiving the first portion and emitting a yellow beam to the first dichroic mirror. The second dichroic mirror is for receiving and separating the yellow beam reflected by the first dichroic mirror into a green and a red beam. The first, second and third light valve are for receiving and modulating respectively the second portion of the blue beam, the green beam and the red beam. The beam combiner is for the beams to form a multi-color image. |
