Abstract
Embodiments of the present invention disclose a naked-eye three-dimensional image display method and device, and the naked-eye three-dimensional image display method comprises: 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.
