Abstract

The embodiment of the invention provides a liquid crystal lens device and a virtual reality zooming method, and belongs to the technical field of virtual reality display. The liquid crystal lens device comprises a phase control assembly and a lens assembly. The phase control assembly comprises a first substrate and a second substrate which are oppositely arranged, a first liquid crystal layer is arranged between the first substrate and the second substrate, and electrode sets used for providing driving voltage for the first liquid crystal layer are arranged on the side, close to the second substrate, of the first substrate at intervals. The lens assembly is located on the side, away from the first substrate, of the second substrate, the lens assembly comprises a third substrate and a focusing structure, the third substrate is close to the phase control assembly relative to the focusing structure, the focusing structure comprises a curved surface bent in the direction away from the third substrate, and a second liquid crystal layer is arranged between the third substrate and the focusing structure. The liquid crystal lens device has the advantages of quick response and simple driving, and is beneficial to wide application in the field of virtual reality.

Description

Technical field[0001]This application belongs to the field of virtual reality display technology, and more specifically, relates to a liquid crystal lens device and a virtual reality zoom method.Background technique[0002]Virtual reality device, abbreviated as VR device, is a product that uses simulation technology and computer graphics, human-machine interface technology, multimedia technology, sensor technology, network technology and other technologies to integrate products, generated by computer, real-time dynamic three-dimensional reality The image brings the user's multi-directional perception of vision, touch, hearing, etc., and responds to the user's input in real time, and then feeds back to the user's facial features. It is a brand-new creation with the help of computers and the latest sensor technology. Human-computer interaction means.[0003]At present, the electronic zoom technology of the virtual reality device realizes zooming by controlling the voltage of the electrode...
