Abstract

Embodiments of the present application provide a liquid crystal lens device and a virtual reality zooming method, which belong to the technical field of virtual reality display. The liquid crystal lens device includes a phase control component and a lens component. The phase control assembly includes a first substrate and a second substrate oppositely arranged, a first liquid crystal layer is arranged between the first substrate and the second substrate, and a spacer is arranged on the side of the first substrate close to the second substrate for providing the first liquid crystal layer. An electrode set that provides a driving voltage. The lens assembly is located on the side of the second substrate away from the first substrate, the lens assembly includes a third substrate and a focusing structure, the third substrate is close to the phase control assembly relative to the focusing structure, and the focusing structure includes a curved surface that is curved in a direction away from the third substrate , a second liquid crystal layer is arranged between the third substrate and the focusing structure. The liquid crystal lens device has the advantages of fast response and simple driving, and is favorable for wide application in the field of virtual reality.
