Abstract:
Disclosed is a lens device, including: a first transparent substrate; a second transparent substrate; and a liquid crystal layer filled therebetween. The first transparent substrate is a Fresnel lens, and a surface of the Fresnel lens toward the liquid crystal layer is disposed with grooves which are spaced from one another in accordance with Fresnel wave zones. The second transparent substrate is configured to control state of a liquid crystal, such that a refractive index of the liquid crystal, when polarized light incident into the liquid crystal passes through the liquid crystal, transforms between a first refractive index of the liquid crystal and a second refractive index of the liquid crystal, wherein the first refractive index is greater than the second refractive index, and a refractive index of the Fresnel lens is substantially equal to the first refractive index of the liquid crystal in the liquid crystal layer.

Claim (Index 17):
The lens device according to  claim 1 , further comprising a driving circuit electrically connected to the first transparent electrode layer and the second transparent electrode layer.
