Abstract
A stereoscopic image projection device and stereoscopic display glasses include a light source system for sequentially generating a first broad spectrum light and a second broad spectrum light; a light splitter for splitting the first broad spectrum light into a first wavelength light and a second wavelength light, each having different wavelengths, and splitting the second broad spectrum light into a third wavelength light and a fourth wavelength light, each having different wavelengths; and a controller for simultaneously controlling the first wavelength light to display a corresponding color in a left-eye image and the second wavelength light to display a corresponding color in a right-eye image, and simultaneously controlling the third wavelength light to display a corresponding color in the left-eye image and the fourth wavelength light to display a corresponding color in the right-eye image. At the same time, the left eye of a viewer can see the first wavelength light or the third wavelength light, and the right eye thereof can see the second wavelength light or the fourth wavelength light, such that the left and right eyes of the viewer simultaneously receive light rays, thus relieving fatigue to the eyes.
