Patent ID: 7605882

Claim:
A method for driving a polymer dispersed liquid crystal hologram comprising: providing a polymer dispersed liquid crystal hologram between a first and second substrate, the first and second substrate having a first and second electrode pattern thereon, respectively, for applying a switching voltage to the polymer dispersed liquid crystal hologram, wherein the first and second electrode patterns consist of interdigitated electrodes; applying a first voltage scheme, wherein a voltage approximately equal to the switching voltage is applied to the interdigitated electrodes on the first substrate and the interdigitated electrodes on the second substrate are connected to ground in order to drive the polymer dispersed liquid crystal hologram off; and removing the first voltage scheme and applying a second voltage scheme, wherein a voltage approximately equal to the switching voltage is applied to every other interdigitated electrode on the first and second substrates and the intermittent electrodes therebetween are connected to ground in order to drive the polymer dispersed liquid crystal hologram on.
