Abstract

In this paper, we present a new LC lens with multi-ring patterned electrode, it consists of two ring-shaped sub-electrodes and a circle sub-electrode, each sub-electrode can be driven separately. The two rings have different diameter but the same center, when the two ring-shaped sub-electrodes are driven independently, the LC lens can work as micro convex lens with different clear aperture and its local length can be tunable along optical axis by electrical signal. As the voltage is applied to the circle sub-electrode, it appears like concave lens. With this design, it can achieve two types microlens effect in one structure, and by applying the voltage to the different patterned electrode, it can switch between two types microlens. The optical properties of the LC microlens are also demonstrated experimentally.
