Patent ID: 8896919

Claim:
A method used in a three-dimensional (3D) display system including a display device configured to display at least two sets of images with parallax for 3D display and a switchable lens coupled with the display device and configured to enable directional light transmission so as to separate the sets of images into predetermined viewing directions to effect the 3D display, the method comprising: receiving operational information of the 3D display system reflecting a change of operational condition of the 3D display system including at least an out-of-range parallax between the sets of images; determining whether to adjust at least one system parameter including a width of the switchable lens with variable width and variable refractive index controlled by activating a number of horizontally-arranged electrodes included in the switchable lens based on the received operational information; determining a target parallax range between the sets of images when it is determined to adjust the system parameter; determining at least a new value for the system parameter of the switchable lens for adjusting the width and refractive index of the switchable lens based on the target parallax range between the sets of images to correct the change of operational condition; and applying the new value to the switchable lens.
