Problems solved by technology

[0006] Although 3D display can bring a shocking stereoscopic visual experience to viewers, some film sources do not require 3D display effects, such as text, pictures, existing ordinary 2D film sources, etc., and viewers watch grating 3D for a long time. Therefore, if the lenticular lens grating 2D / 3D display compatibility can be achieved, a naked-view 2D / 3D compatible display can be developed, so that the viewer can freely display in 2D and 3D Switching between, and does not need to take off and wear the vision aid frequently, it will be more widely used

Abstract

The invention discloses a large optically anisotropic liquid crystal composition. The liquid crystal composition consists of a compound with a structural formula I, a compound with a structural formula II, a compound with a structural formula III and a compound with a structural formula IV; according to the liquid crystal composition, a series of liquid crystal materials with various structures are blended, and particularly a double-alkyne compound with extremely high optical anisotropy and maximum (delta)n of greater than 0.600 is adopted for the first time, so that the liquid crystal composition has great optical anisotropy; and meanwhile, the liquid crystal composition has high clearing point, appropriate dielectric anisotropy and acceptable rotary viscosity, and is particularly suitable for a liquid crystal display element LC-Lens and favorable for producing a thinner and more practical LC-Lens product by the device factory so as to obtain better visual experience and smooth 2D / 3D conversion effect.

Description

technical field [0001] The invention relates to a liquid crystal composition, in particular to a liquid crystal composition with large optical anisotropy for a liquid crystal display element LC-Lens. Background technique [0002] Stereoscopic video, commonly known as 3D video, is a multimedia form that enables people to experience a strong stereoscopic visual impact through binocular or multi-eye visual signals. It has great application value in aerospace, military, medical, education, entertainment and other fields . In recent years, 3D technology has gradually become a research hotspot in many disciplines such as computer vision, graphics, image and video processing and communication. At the same time, due to the vigorous development of film and television industry, the development of 3D TV industry has become an inevitable trend. [0003] Different from the current common 2D displays, 3D display refers to the use of various technical means such as optics to simulate the ...
