Problems solved by technology

[0007] In order to solve the problem that the current liquid crystal material is used in such as lens-type naked-eye 3D, the alignment of the liquid crystal lens is not good; as the use time increases, the temperature of the screen rises and the display effect deteriorates. The invention provides an alignment liquid crystal material. By using high-definition bright Liquid crystal material, and add a certain proportion of reactive monomer RM (Reactive Monomer), through the method of light, so that the internal surface has a certain pre-tilt angle, so as to solve the problem of poor alignment; at the same time, the high-definition bright spot material can improve the refraction Rate temperature dependence, improve display quality

Abstract

The invention relates to an alignment liquid crystal material and application thereof, and belongs to the field of liquid crystal materials. The alignment liquid crystal material comprises one or more monomeric compounds as shown in a general formula I, one or more monomeric compounds as shown in a general formula II, one or more monomeric compounds as shown in a general formula III and one or more monomeric compounds as shown in a general formula IV. The alignment liquid crystal material can be applied to lens type naked eye 3D display, the alignment problem can be solved, and the display quality is improved. The problem of poor alignment is solved, meanwhile, the liquid crystal material has a high clearing point and good temperature dependency, and it can be guaranteed that ne of a liquid crystal lens is approximate to the refractive index of a columnar structure under the condition that a screen works continuously, so that the display quality of the liquid crystal lens is guaranteed.

Description

technical field [0001] The invention relates to an alignment liquid crystal material and its application, which is mainly used to improve the alignment problem, and can be applied in lens-type naked-eye 3D display, and belongs to the field of liquid crystal materials. Background technique [0002] In the prior art, the liquid crystal lenticular lens is mainly attached to the TFT module. When the power is turned off, the liquid crystal "lyes" horizontally in the lens, and at this time the liquid crystal has a refractive index n e = The refractive index of the lenticular lens material is ≈1.60, the light does not deflect, the liquid crystal lens does not work, the light goes out of the lens and enters the human eye, and the display mode is 2D at this time. When the power is turned on, the liquid crystal in the liquid crystal lens "stands and rotates", and the refractive index of the liquid crystal is n o <The refractive index of the cylindrical lens material, the light is ...
