For some functions such as lenses, gratings, axicon and vortex applications a stable phase response is required. This can functions be accomplished driving the high retardation display - superposition of CGH's with basic optical functions to versions with low voltage settings for 2  phase retardation, combine functionalities however compromising the response time.
