Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Such as image 3 As shown, the dielectric anisotropy constant Δε of the dual-frequency liquid crystal material will change with the change of the driving voltage frequency f. When the high-frequency driving voltage is used, the dual-frequency liquid crystal material exhibits a negative liquid crystal with Δε<0. The frequency at which this curve intersects the horizontal axis is called the separation frequency or transition frequency fc. Wherein, the frequency of the high-frequency driving voltage is higher than the separation frequency, and the frequency of the low-frequency driving voltage is lower than the separation frequency.

[0033] In the embodiment of the present invention, dual-frequency liquid crystals are used in liquid crystal l...

Abstract

The invention provides a 2D-3D switching stereoscopic display device and a liquid crystal lens, which belong to the technical field of stereoscopic display. The liquid crystal lens comprises a first substrate with a first electrode formed thereon and a second substrate with a second electrode formed thereon, as well as a polymer layer and a liquid crystal layer which are arranged between the first electrode and the second electrode, wherein the liquid crystal layer adopts double-frequency liquid crystal; and an arc-shaped boundary is formed between the polymer layer and the liquid crystal layer. According to the invention, the hysteresis effect caused when the stereoscopic display device is switched from 2D to 3D is improved, and therefore the display effect of the stereoscopic display device is improved.

Description

technical field [0001] The invention relates to the technical field of stereoscopic display, in particular to a 2D-3D switchable stereoscopic display device and a liquid crystal lens. Background technique [0002] As we all know, the 2D displays we usually see cannot provide us with depth information like the real world. The key reason why we can distinguish the depth of field (3D effect) is that the two eyes of a person have a positional difference caused by an interpupillary distance of about 60mm. The two pictures with "binocular parallax" become a pair of "stereoscopic image pair", which, through the fusion of the visual cortex of the human brain, produces a stereoscopic effect. [0003] 3D display is divided into naked-eye type and glasses type. The mainstream technologies of glasses type include shutter glass technology and pattern retard, while naked-eye type mainly includes parallax barrier grating, cylindrical lens grating and liquid crystal lens (LC Lens) ) grati...
