Problems solved by technology

[0004] Traditional wavelength multiplexed stereoscopic display devices use two sets of light sources to provide two sets of three primary colors. However, the laser light source commonly used as a light source, whose wavelength is in the green, is not efficient, and the cost is so high that the light source accounts for a large proportion of the cost. Substantial Increase

Embodiment Construction

[0053] In view of the known six-primary-color light sources that provide two sets of independent light sources, the three primary colors (red, green, and blue) of each set of independent light sources are composed of laser light sources. However, due to the low efficiency and high price of the green laser, the overall cost of the light source increases. In addition, as two independent light sources, the red laser must select two sets of wavelengths with high discrimination rate. In order to select an appropriate laser light source, the overall cost of the light source will inevitably increase.

[0054] The six-primary-color solid-state light source of the present invention uses a laser light source and a photoluminescent element as a light source, wherein part of the light beam emitted by the laser light source excites the photoluminescent element, and the excited light is used together with another part of the laser line as a light source. And with a multi-band filter, the op...

Abstract

The invention provides a hexa-chromatic solid light source. The hexa-chromatic solid light source comprises a blue light output unit, wherein the blue light output unit continuously outputs a first blue light and a second blue light simultaneously, wavelength scopes of the first blue light and the second blue light are different from each other, in a first mode, the first blue light and the second blue light are modulated to be S polarization light which is outputted to form a first combination light, in a second mode, the first blue light and the second blue light are modulated to be P polarization light which is outputted to form a second combination light.

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 providing stereoscopic display. Background technique [0002] Utilizing the binocular parallax of human beings, known stereoscopic display devices provide different images for the two eyes of the viewer to achieve 3D display. According to different methods for achieving different images, stereoscopic display devices include polarization, red and blue, or wavelength multiplexing. [0003] The wavelength multiplexed stereoscopic display device, as its name implies, realizes three-dimensional display by providing images with different wavelength ranges to the viewer. And because the color image mostly mixes the various colors in the color gamut space by the additive three primary colors (R (red), G (green), B (blue)), so the known wavelength multiplexing stereoscopic display device uses two groups of three primary colors R...
