Abstract

The invention belongs to the technical field of laser projection and relates to a backboard dimming device and a laser projector. The backboard dimming device comprises a mounting plate used for mounting a backboard and a fixing seat, the mounting plate and the fixing seat are arranged at an interval, the mounting plate is connected with the fixing seat through a movable connecting assembly, the mounting plate rotates in the horizontal or vertical direction relative to the fixing seat, and at least two driving assemblies for driving the inclination angle of the mounting plate to be adjusted in the horizontal and vertical directions are arranged between the mounting plate and the fixing seat. With the backboard dimming device and the laser projector of the invention adopted, the color fidelity of a picture can be improved, and better white light can be realized.

Description

technical field [0001] The present application relates to the technical field of laser projection, in particular to a backplane dimming device and a laser projector. Background technique [0002] Laser projection uses laser beams to transmit the image to be displayed. The optical components of laser projection mainly include red, green, and blue three-color light sources. The three-color light is refracted and combined to form a colored light source and then projected onto the background through the projection lens. [0003] The patent application document with the application publication number CN111142267A discloses a high-power RGB synthetic laser light source system, including three beam integration components corresponding to red light, green light and blue light, and the beam synthesis optical paths of the three beam integration components Combining assembly, the optical path combining assembly includes a second reflector, a third reflector and a fourth reflector arran...
