Display device for three-dimensional display having first and second color wheels

摘要

A display includes a light source, a first color wheel, a second color wheel, an actuator, a controller, and a light modulator. The light source is for providing a light beam. The first color wheel includes plural primary-color filtering areas, and the second color wheel includes plural left or right eye filtering areas. The actuator rotates the first color wheel and the second color wheel. The controller is for controlling the rotations of the first color wheel and the second color wheel, such that the light beam passing through the first color wheel and the second color wheel is filtered to plural left or right eye primary-color light beams with different spectra. The light modulator is for modulating the left or right primary-color light beams and projecting the modulated left or right primary-color light beams onto a screen to display an image.

主权项

1. A method for displaying, comprising:
providing a light beam having a light path; rotating a first color wheel with plural primary-color filtering areas and a second color wheel with plural left or right eye filtering areas in a three-dimensional display mode, wherein each of the primary-color filtering areas has a primary-color passband, each of the primary-color filtering areas corresponds to at least two of the left or right eye filtering areas, each of the left or right eye filtering areas filters out a portion of the primary-color passband of the corresponded primary-color filtering area, the primary-color filtering areas and the corresponding left or right eye filtering areas are disposed in the light path in sequence when the first color wheel and the second color wheel rotate, and the primary-color filtering area and the left or right eye filtering area that are simultaneously in the light path overlap, such that the light beam passing through the first color wheel and the second color wheel is filtered to plural left or right eye primary-color light beams with different spectra; and modulating the left or right eye primary-color light beams and projecting the modulated left or right eye primary-color light beams onto a screen to display an image.
