Abstract

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 is further operable to pass temporally modulated color display images of at least first, second, and third wavelengths being applied to a display surface, further including first, second, and third holding voltages to the LC cell in decreasing magnitude to stabilize the retardation of the lens for first, second, and third display image wavelengths.
