Abstract: A liquid crystal lens, a driving method, eyeglasses, an electronic product, a VR device, and an AR device are provided. The liquid crystal lens comprise a liquid crystal layer, a first electrode layer, a second electrode layer, a first transparent substrate, and a second transparent substrate. The first and second electrode layers are respectively located on opposite sides of the liquid crystal layer. The first transparent substrate is positioned on side of the first electrode layer opposite to the liquid crystal layer, and the second transparent substrate is positioned on the side of the second electrode layer opposite to the liquid crystal layer. The second electrode layer includes a first electrical connector, a second electrical connector, and several conductive wires. The driving method of the liquid crystal lens is simple and can achieve an ideal potential distribution, unaffected by variations in the characteristics of high-resistance films.

Abstract: A liquid crystal lens includes a liquid crystal layer, a first electrode layer, a second electrode layer, transparent substrates. The second electrode layer includes multiple electrode units arranged sequentially from a position adjacent to a center thereof r toward a position away from the center thereof. Each of the electrode units includes at least one conductive line which extends from a first position of the electrode unit to a second position of the electrode unit. A distance between the second position and the center of the second electrode layer is greater than a distance between the first position and the center of the second electrode layer. A spacing distance between adjacent conductive lines is less than or equal to 100 μm. A way of driving the liquid crystal lens is simple, and an ideal potential distribution can be obtained and not affected by change of characteristics of a high-resistance film.
