Description

A kind of liquid-crystal composition and liquid crystal lens
Technical field
The present invention relates to technical field of liquid crystal display, particularly relate to a kind of liquid-crystal composition and liquid crystal lens thereof.
Background technology
Devices such as camera, mobile phone camera, the demonstration of 3D stereopsis, phase modulator often utilize zoom lens that image is amplified or dwindles and form images.The traditional zoom camera lens is provided with a plurality of mirror crowds (lens group), through moving along optical axis direction between the mirror crowd, with change spacing each other, thereby whole focal length is changed, but does not influence image-forming range.Yet this kind camera lens needs long mirror crowd miles of relative movement, cause the mechanism volume big, regulate slowly, focusing range is limited, cost an arm and a leg, install that to drive consumed energy big and damage easily etc.
For seeking the method that substitutes mechanical focusing; And can change focal length on a large scale; Prior art utilizes electric field to control the liquid-crystal zoom lens of focal length (Liquid Crystal lens); Form special electric field through on the electrode of band circular hole, applying voltage; Liquid crystal molecule in the electric field is deflected, thereby light is played the effect that disperses or assemble.It is actual to be a kind of simulated optical element, through between electrode, applying the specific optical lens characteristic that different voltages with different can realize easily that we want.
Wherein, column liquid crystal lens grating is a kind of device that utilizes electric field to form lens in the prior art, can realize 3D stereo display.Said column liquid crystal lens grating is through etching the strip transparent ITO electrode on transparent glass substrate; On this electrode, apply different voltages with different then and form electric field; Liquid crystal molecule in the electric field is deflected; Thereby change the incident direction of light, the variation of variation through voltage and number of electrodes simultaneously changes focal length and the pitch of column liquid crystal lens grating etc.
But because each component of liquid-crystal composition has different physicalies, so the parameters combination of each component of liquid-crystal composition has determined each performance of liquid-crystal composition.Wherein, For realizing the superiority of the column physical grating that column liquid crystal lens grating is more traditional; Need column liquid crystal lens grating under 60Hz, 120Hz or higher frequency, can freely switch,, then need a kind of liquid-crystal composition with high speed response property to this.Following relation is arranged between each variable of the liquid-crystal composition relevant with the response performance of column liquid crystal lens grating:
Relational expression one: T On=(γ 1d 2/ k11 π 2)/[(V/Vth) 2-1]
Relational expression two: T Off=γ 1d 2/ k11 π 2
Wherein, γ 1 is a rotary viscosity, and d is a thickness of liquid crystal layer, and K11 is the bent elastic constant of exhibition, and V is a driving voltage, and Vth is a threshold voltage.Can find out from the above-mentioned relation formula, the rotary viscosity through reducing liquid-crystal composition or improve it and open up bent elastic constant, or reduce thickness of liquid crystal layer, can shorten its time of response.Yet if reduce rotary viscosity to improve the time of response, bent elastic constant of the exhibition of liquid crystal and transformation temperature also will descend thereupon, and, increase if open up bent elastic constant, then threshold voltage and rotary viscosity will be tending towards increasing.Simultaneously, if will reduce thickness of liquid crystal layer, then the degree of birefringence of liquid-crystal composition will increase, and this can cause rotary viscosity to increase equally.Therefore, for improving the time of response, it is minimum that the equilibrium relationship between these three influence factors must reduce to.
In addition, degree of birefringence also is an important physical characteristic of liquid crystalline cpd.Common TN, STN show that degree of birefringence with liquid crystal material is generally between 0.12 to 0.20; TFT shows that degree of birefringence with liquid crystal material is generally between 0.065 to 0.135; PDLC and multistable show generally need be greater than 0.20 with the degree of birefringence of liquid crystal material, and 3D stereo display generally is greater than 0.25 with the degree of birefringence of the liquid crystal material of liquid crystal lens (Liquid Crystal lens).
Seeing that each components selection of liquid-crystal composition and proportioning have determined each performance of liquid-crystal composition; And the performance perameter of the liquid-crystal composition of prior art fails to realize comparatively ideal combination; Therefore, be necessary further optimization is done in selection of the monomer liquid crystal in the liquid-crystal composition and set of dispense ratio.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of liquid-crystal composition and liquid crystal lens thereof, fails to realize the problem of more satisfactory combination with the performance perameter of the liquid-crystal composition that solves prior art.
The invention provides a kind of liquid-crystal composition, this liquid-crystal composition comprises:
