Claim:
1. A transmissive liquid crystal (LC) control structure comprising: a first substrate having a first surface having a gallium nitride high electron mobility transistor (GaN HEMT) structure disposed thereon to provide a conductor on the first surface of said first substrate; a second substrate having a first surface disposed over and spaced apart from the first surface of said first substrate and having a GaN HEMT structure disposed thereon to provide a conductor on the first surface of said second substrate and wherein the GaN HEMT structure on one of the first and second substrate surfaces are patterned into individual electrodes; a polymer network liquid crystal (PNLC) disposed in the space between the first surface of said first substrate and the first surface of said second substrate; and a control circuit coupled to the individual electrodes.
