Six-primary-color solid light source and operation method thereof

Abstract

A six-primary-color solid light source comprises a first light source, a second light source, a third light source, a first photoluminescence member, a second photoluminescence member and a multi-frequency-range filter, wherein the first light source provides a light beam of the first wavelength, the first photoluminescence member provides a light beam of the second wavelength after being excited, the second light source provides a light beam of the third wavelength, the third light source provides a light beam of the fourth wavelength, and the second photoluminescence member provides a light beam of the fifth wavelength after being excited; the light beams of the first light source, the second light source and the first photoluminescence member penetrate the multi-frequency-range filter and then form a first primary color combination; and the light beams of the third light source and the second photoluminescence member are reflected by the multi-frequency-range filter and then form a second primary color combination.

Description

technical field [0001] The invention relates to a six-primary-color solid-state light source, in particular to a six-primary-color solid-state light source for stereoscopic display. Background technique [0002] Utilizing the binocular parallax of human beings, existing stereoscopic display devices provide different images for the two eyes of the viewer to achieve 3D display. According to the differences in the ways to achieve different images, stereoscopic display devices include polarized, red and blue or wavelength multitasking. [0003] The wavelength multi-tasking 3D display device, as its name implies, is to provide viewers with images with different wavelength ranges to achieve 3D display. And because the color image mostly mixes various colors in the color gamut space by the addition of three primary colors (R (red), G (green), B (blue)), so the existing wavelength multitasking stereoscopic display device uses two sets of The three primary colors R1, G1, B1 and R2,...

AI Technical Summary

Problems solved by technology

[0004] Traditional wavelength multitasking stereoscopic display devices use two sets of light sources to provide two sets of three primary colors. However, laser light sources commonly used as light sources, whose wavelength is in the green, are not efficient and expensive, causing the cost ratio of the light source to be high.
