Liquid crystal lens with focusing plane capable of being scanned and manufacturing method thereof

Abstract

The invention provides a liquid crystal lens with a focusing plane capable of being scanned and a manufacturing method thereof. The lens includes a first control layer, a second control layer, a liquid crystal layer and a control module; the liquid crystal layer is arranged between the first control layer and the second control layer; the control module is connected with the first control layer and the second control layer separately; the first control layer includes a first transparent base plate, a first driving electrode, a first insulation layer, a second driving electrode, a first alignment layer and a first high-impedance layer; the second control layer includes a second transparent base plate, a third common electrode, a second high-impedance layer and a second alignment layer. Thecraftsmanship of the liquid crystal lens is simple, not only can focal length adjustability of the liquid crystal lens be achieved, but also uniformly-spaced and seamless scanning switch of the focusing plane of the liquid crystal lens can be achieved, and therefore the effect of the dynamic liquid crystal lens is achieved.

Description

technical field [0001] The invention relates to a liquid crystal lens, in particular to a liquid crystal lens with a focus plane scannable and a manufacturing method thereof. Background technique [0002] Two-dimensional (Two-dimension, 2D) image information can bring people clear and colorful 2D visual effects, but the real world in which people live is three-dimensional (There-dimension, 3D), and two-dimensional images cannot provide real The depth information or disparity image information of the world cannot meet the needs of human society. Recreating the real three-dimensional world is the dream of human beings, and it is also the goal pursued by scientific and technological researchers. 3D images can reproduce depth information or parallax image information, which is in line with the human visual habit of observing the objective world. With the continuous development of 3D image information acquisition and display technology, people's reproduction of depth image info...

The structure of the liquid crystal lens is simple, the focal length can be adjusted under the applied voltage, and the focus plane can be moved by moving the position of the driving electrode; however, the electric field distribution inside the driving electrode of the liquid crystal lens is not uniform, and the driving voltage of the device is high; Because there is a gap between the drive electrodes of the lens, there is a gap when the focus plane moves
