Abstract
A 3D image display system with high resolution is disclosed. The system may deflect left and right eye images to a left and right eye of a viewer, respectively. As such, the viewer can see 3D images. With a time-sharing mode, all of electronically switchable light modulating cells are configured to modulate all of the images deflected to the left eye of the viewer during a first period, and modulate all of the images to the right eye of the viewer during a second period, and the first period and the second period are alternate periods. Alternatively, a part of the electronically switchable light modulating cells are configured to modulate left eye images deflected to the left eye of the viewer, and another part of the electronically switchable light modulating cells are configured to modulate right eye images to the right eye of the viewer during the same period.
