Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 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…
