Abstract
There is disclosed an optical display arrangement. The optical display arrangement includes an optical element, a voltage source connected to the optical element and a controller operatively coupled to the voltage source. The controller is operable to control the voltage source to apply a first voltage pulse over an operating voltage for a first period of time, to the optical element, to switch the optical element from a first optical state to a second optical state wherein the first voltage pulse is a sum of elevated voltage and operating voltage. Furthermore, the controller is operable to provide the operating voltage to the optical element to maintain the optical element in the second optical state. Moreover, the controller is operable to remove the operating voltage from the optical element to switch the optical element from the second optical state to the first optical state.
