Abstract
A parallax barrier 3D display utilizes adjustable at least one parallax barrier for having an observer always retrieve stereo vision no matter whether horizontal or vertical movements towards the parallax barrier 3D display are made. The parallax barrier is adjustable in its width and a distance from the parallax barrier 3D display, or a parallax barrier having an appropriate width or distance may be chosen from each parallax barrier set. Therefore, the observer does not have to search for sweet spots nor keep on staying at the sweet spots for retrieving stereo vision.
Claims12
An adjustable parallax barrier 3D display comprising:
- a display;
- a main parallax barrier disposed in front of the display;
- a tracking system for tracking locations of both eyes of an observer in front of the main parallax barrier;
- and
- a controller for computing at least one of 3D display parameters according to the tracked locations of the eyes,
- wherein the main parallax barrier is adjusted according to the at least one of 3D display parameter to shelter a left-eye image being seen by a left eye of the observer and shelter a right-eye image being seen by a right eye of the observer.
