Patent ID: 8427394

Claim:
A method for driving at least one shutter glass lens having a property of light retardation that is variable at least according to the wavelength of the light passing through it, the shutter glass lens having an LC cell driven to a relatively “on” or a relatively “off” state according to a voltage applied across it, the lens operable to pass temporally modulated color display images of at least first, second, and third wavelengths being applied to a display surface, the method comprising: a) applying a first holding voltage to the LC cell to stabilize the retardation of the lens for the first wavelength; b) providing a first temporally modulated color display image on the display surface after applying the first holding voltage; c) applying a second holding voltage to the LC cell to stabilize the retardation of the lens for the second wavelength; d) providing a second temporally modulated color display image on the display surface after applying the second holding voltage; e) applying a third holding voltage to the LC cell to stabilize the retardation of value for the third wavelength; f) providing a third temporally modulated color display image on the display surface after applying the third holding voltage; and g) between applying the holding voltages, removing voltage from the LC cell; wherein the removing voltage and the applying the first, second, and third holding voltages occur during the relatively “on” state.
