Problems solved by technology

Specifically, when the position of the stereoscopic display device is determined, the direction of the liquid crystal lens array is also determined, and the observer can only see the stereoscopic display in a specific direction. When the position of the observer relative to the stereoscopic display device deviates from the specific direction , due to the difference in refractive index at different positions when the stereoscopic display device performs 3D display, the chromatic aberration of the stereoscopic display device is relatively large, and a good 3D display effect cannot be obtained

Abstract

The invention provides a liquid crystal lens array and a three-dimensional display device and belongs to the technical field of display. The liquid crystal lens array comprises a first substrate, a second substrate opposite to the first substrate, and a liquid crystal layer between the first substrate and the second substrate. A plurality of first electrodes distributed in an arrayed mode are arranged on the surface, close to the liquid crystal layer, of the first substrate. A second electrode is arranged on the surface, close to the liquid crystal layer, of the second substrate. Each first electrode comprises at least two annular electrodes, wherein insulating layers are arranged between every two adjacent annular electrodes, and projection layers, on the liquid crystal layer, of the at least two annular electrodes are arranged layer by layer in a sleeving mode. The invention also provides another liquid crystal lens array. First electrodes of the liquid crystal lens array comprise annular electrodes and spiral electrodes arranged in small circles of the annular electrodes and connected with the annular electrodes. Besides, the invention further provides the three-dimensional display device using the liquid crystal lens array. 3D view angles of the three-dimensional display device are effectively increased.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a liquid crystal lens array and a three-dimensional display device. Background technique [0002] Among various technologies for achieving stereoscopic display, compared with glasses-type 3D display technology, naked-eye 3D has become a hotspot in the research of 3D display technology due to the convenience of not needing other auxiliary equipment and its advantages in application. The applications in the fields of personal consumer goods and commercial fields are also becoming more and more extensive, such as small-sized glasses-free 3D mobile phones, small and medium-sized glasses-free 3D tablets, and large-size glasses-free 3D advertising machines. [0003] Among the various technologies for realizing naked-eye 3D display, the parallax barrier technology is the most mature. As a kind of parallax barrier technology, the liquid crystal slit grating three-dimensional...
