Problems solved by technology

[0007] like image 3 , for a common liquid crystal lens stereoscopic display device, since the left and right eyes of the viewer correspond to the space-divided left and right images respectively, when each liquid crystal lens unit of the liquid crystal lens array 110 and the column pixels of the 2D display device 120 follow a certain When the angle θ is set, in order to obtain a 3D image by fusion of the left and right images using space segmentation, the stereoscopic display device sacrifices a certain resolution in the x direction or the y direction

Embodiment Construction

[0036] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0037] An embodiment of the present invention provides a liquid crystal lens array, such as Figure 4 As shown, the liquid crystal lens 1000 includes a plurality of liquid crystal microlens units (such as L1, L2 and L3, etc., only three microlens units are shown in the figure as an example), and each microlens unit (such as L1, L2 and L3 etc.) have the same structure.

[0038] Such as Figure 4 As shown, the liquid crystal lens unit includes a first substrate 1001 and a second substrate 1002 . The first substrate 1001 and the second substrate 1002 are facing and spaced apart. Specifically, the first substrate 1001 and the second substrate 1002 may be transparent substrates such as glass, and each substrate has the same or similar refractive index.

[0039] Such as Figure 4 Among them, the height direction of t...

Abstract

The invention relates to the technical field of auto-stereoscopic display, in particular to a liquid crystal lens array, a stereoscopic display device and a drive method. The liquid crystal lens array comprises a plurality of lens units. Each lens unit comprises a first substrate and a second substrate. The side surface of each first substrate is covered with a first dielectric layer, the side surface of each first dielectric layer is provided with a first horizontal alignment film, and a first electrode and a second electrode are arranged between each first substrate and the corresponding first horizontal alignment film. Each second substrate is covered with a second horizontal alignment film, the difference between the friction direction of each second horizontal alignment film and the friction direction of the corresponding first horizontal alignment film is 180 degrees, and the side surface of each second substrate is covered with a third electrode. A first liquid crystal layer is arranged between each first substrate and the corresponding second substrate in a packaging mode. By means of the liquid crystal lens array, the stereoscopic display device and the drive method, high-resolution 3D images can be observed based on the effect of persistence of vision of human eyes.

Description

technical field [0001] The invention relates to the technical field of autostereoscopic display, in particular to a liquid crystal lens array, a stereoscopic display device and a driving method. Background technique [0002] In 3D stereoscopic display technology, glasses-free 3D has become the focus of 3D display technology research because of the convenience of viewing 3D effects without other auxiliary equipment and its advantages in application. Among various naked-eye 3D display technologies, autostereoscopic display devices using liquid crystal lenses and liquid crystal slit gratings have attracted widespread attention due to their respective unique advantages. [0003] The three-dimensional display device realized by liquid crystal lens mainly utilizes the positive and negative electrodes respectively arranged on the two substrates on both sides of the liquid crystal layer, and different driving voltages are applied to the different electrodes, so that the two substrat...
