Hybrid liquid crystal lens and method for driving thereof

Abstract

Disclosed is a hybrid liquid crystal lens (100) comprising: an index-matching LC lens (102); a Gradient Refractive Index (GRIN) LC lens (104), wherein the GRIN LC lens and the index-matching LC lens are arranged in a stacked configuration; a first driving circuit (106) configured to drive the index-matching LC lens using a first drive signal, to produce a first optical power; and a second driving circuit (108) configured to drive the GRIN LC lens using a second drive signal, to produce at least one second optical power, wherein a combination of the at least one second optical power and the first optical power produces at least one third optical power of the hybrid LC lens.
