Abstract

The invention discloses a red-green-blue laser projection light source and a DLP laser projection display device. The red-green-blue laser projection light source comprises a red laser light source device, a green laser light source device, a blue laser light source device, a liquid cooling plate, a coupling module, a cooling device and a reflection device. According to the red-green-blue laser projection light source and the DLP laser projection display device, the brightness of the light source and the effective utilization rate of the light energy are improved, the non-uniformity and speckle problem of the laser light source are successfully solved, and the damage of a rear-end imaging system due to excessive centralization of local light energy is avoided. Moreover, the red-green-blue laser projection light source and the DLP laser projection display device have the characteristics of being wide in color gamut, long in service life, environment-friendly and energy-saving, and have high application value in the field of projection display.

Description

technical field [0001] The invention relates to the technical field of laser projection, in particular to a red, green and blue three-color laser projection light source and a DLP laser projection display device. Background technique [0002] The luminous intensity and spectrum of the ultra-high pressure mercury lamps, metal halide lamps, xenon lamps, halogen lamps, LED light sources, blue light laser excitation silver powder light sources and other light sources used in the existing projection system lighting are all affected by the luminescent substances and their states. Restricted, showing the characteristics of continuous or banded spectrum. After the LED light source is produced as a light source, 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. The LED light source can meet the real-time adjustment requirements of the white field color coord...
