Title:
LIQUID CRYSTAL LENS, DRIVING METHOD, GLASSES, ELECTRONIC PRODUCT, AND VR/AR DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/141738
Kind Code:
A1
Abstract:
A liquid crystal lens, a driving method, glasses, an electronic product, and a VR/AR device. The liquid crystal lens comprises a liquid crystal layer (30), a first electrode layer (20), a second electrode layer (40), a first transparent substrate (10) and a second transparent substrate (50). The first electrode layer (20) and the second electrode layer (40) are respectively arranged on two opposite sides of the liquid crystal layer (30). The first transparent substrate (10) is arranged on the side of the first electrode layer (20) facing away from the liquid crystal layer (30), and the second transparent substrate (50) is arranged on the side of the second electrode layer (40) facing away from the liquid crystal layer (30). The second electrode layer (40) comprises a first electrical connection member, a second electrical connection member and a plurality of conductive wires (431). The conductive wires (431) extend from the center of the second electrode layer (40) to the periphery. One end of each conductive wire (431) is electrically connected to the first electrical connection member, and the opposite end of the conductive wire (431) is connected to the second electrical connection member. The interval between adjacent conductive wires (431) is less than or equal to 100 μm. The liquid crystal lens has a simple driving mode, can form desirable potential distribution, and is immune to the characteristic change of a high-resistance film.
