Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0023] With the development of optoelectronic technology, the requirements for the display effect of the projection screen of the projection device are getting higher and higher. At present, the coherence of the light emitted by the light source of the projection device is relatively strong, resulting in relatively serious speckle effect in the projection picture projected by the projection device, and the display effect of the projection picture is poor. Embodiments of the present application provide a multicolor light source and a projection device, which can reduce the speckle effect in a projected picture and improve the display effect of the projected picture.

Abstract

The invention discloses a multicolor light source and projection equipment, and belongs to the technical field of photoelectricity. The multicolor light source comprises a laser, a light combining assembly and a polarity adjusting component. The laser is used for emitting lasers with various colors to the light combining assembly, and the light combining assembly is used for mixing the lasers with various colors and then emitting the mixed laser to the polarity adjusting component; and the polarity adjusting component is used for adjusting the polarization direction of at least part of the incident laser to obtain a target laser, and at least one color of laser in the target laser meets the condition that the polarization direction of a part of laser in the same color is different from the polarization direction of the rest of laser. The problem that the projection effect of the projection equipment is poor is solved. The multicolor light source is used for projection.

Description

[0001] The embodiment of this application claims the priority of the Chinese patent application with the application number 202110599419.3 and the invention title "Multicolor Light Source and Projection Device" submitted on May 31, 2021, the entire contents of which are incorporated by reference in the embodiment of this application . technical field [0002] The present application relates to the field of optoelectronic technology, in particular to a multi-color light source and projection equipment. Background technique [0003] With the development of photoelectric technology, the requirements for the projection effect of projection equipment are getting higher and higher. [0004] In the related art, a laser is used as a light source of a projection device, and the laser light emitted by the laser is modulated and then projected onto a screen, thus realizing the projection display of the projection device. However, the coherence of the laser light emitted by the laser i...
