Abstract

The invention relates to the technical field of laser projection technology, and particularly relates to a laser display device. The laser display device comprises a laser projection light source and an imaging module, wherein the laser projection light source comprises a first laser module, a second laser module, a third laser module and a first coupling module; the first coupling module comprises a first coupling mirror, a motor and a first light stick; the first coupling mirror is used for coupling a laser beam emitted from the laser module and outputting the laser beam to the first light stick; and the first light stick is arranged in a hollow shaft of the motor and is driven through the hollow shaft to carry out rotary motion, so that a first coupled beam is output after being reflected for multiple times in the first light stick. Through the mode of driving the first light stick to carry out rotary motion by adopting the motor, a mixed light mode of time and space is skillfully achieved and the problems of nonuniformity and speckles of a laser light source are solved, so that the laser display device can display an ideal picture.

Description

technical field

[0001] The invention relates to the technical field of laser projection, in particular to a laser display device. Background technique

[0002] The luminous intensity and spectrum of light sources such as ultra-high pressure mercury lamps, metal halide lamps, xenon lamps, halogen lamps, LED light sources, and blue laser-excited phosphor light sources used in existing projection system lighting are limited by luminescent substances and their states. Shows the characteristics of continuous or banded spectrum. Except for LED light sources, after these light sources are produced, the white point coordinates of the light source are fixed, which cannot well meet the real-time adjustment requirements of the white point color coordinates in the later stage. Although the LED light source can meet the real-time adjustment requirements of the white field color coordinates in the later stage, the LED light source itself has low brightness and low utilization rate, and i...
