NAKED-EYE THREE-DIMENSIONAL IMAGE DISPLAY METHOD AND DEVICE
First Claim
1. A naked-eye three-dimensional image display method, comprising:
- with a control means, making a two-dimensional display screen display a left-eye image at a first moment, and synchronously applying a first set of voltages to a liquid crystal lens located at a light-exiting side of the two-dimensional display screen, so that the left-eye image is projected through the liquid crystal lens to a left eye of an observer; and
with the control means, making the two-dimensional display screen display a right-eye image at a second moment, and synchronously applying a second set of voltages to the liquid crystal lens, so that the right-eye image is projected through the liquid crystal lens to a right eye of the observer;
wherein a time interval between the first moment and the second moment is not more than visual persistence time of human eyes.

9. A naked-eye three-dimensional image display device, comprising:
-
a display screen, for displaying a two-dimensional image; a control means; and a liquid crystal lens, located at a light-exiting side of the display screen; wherein the control means is adapted for making the display screen display a left-eye image at a first moment, and synchronously applying a first set of voltages to the liquid crystal lens, so that the left-eye image is projected through the liquid crystal lens to a left eye of an observer; the control means is further adapted for making the display screen display a right-eye image at a second moment, and synchronously applying a second set of voltages to the liquid crystal lens, so that the right-eye image is projected through the liquid crystal lens to a right eye of the observer; and a time interval between the first moment and the second moment is not more than visual persistence time of human eyes. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
