Description
Technical field
The present invention relates to a kind of display panels and driving method thereof, particularly a kind of blue-phase liquid crystal display panel (bluephaseliquidcrystaldisplaypanel) and driving method thereof.
Background technology
1888 Christian eras, cholesterol type benzoate (Cholestericbenzoate) is placed in polarizing microscope by FriedrichReinitzer, observe cholesterol type benzoate and can present different colours (bluish violet and blueness) in even phase (Isotropic) and cholesterol phase (Cholesteric), the color variation phenomenon between even phase and cholesterol phase exists only in very little temperature range (about only having 1 DEG C of temperature range).In 1970 Christian eras, many scientists utilize the method such as analysis by measure, high resolving power differential scanning calorie meter, confirm that aforementioned phenomenon is a kind of new thermodynamically stable phase, and are called blue phase.
Indigo plant has three kinds of out of phase existence mutually, and these three kinds are expressed as BPI, BPII, BPIII mutually, and BPIII exist temperature be three mutually in the highest, the BPIII mentioned in the literature is " fogphase ".Compared to the cube structure (cubic) of BPI and BPII, BPIII is unformed (amorphous).At polarized light microscopy Microscopic observation, BPIII, normally without the fuzzy image of any structure, is therefore difficult to polarized light microscopy Microscopic observation.
And the structure of BPI, BPII has been proved, the elementary cell forming BPI, BPII has been " two torsion is cylindric " (DTC:doubletwistcylinder), and such arrangement mode has minimum free energy.In addition, two torsion cylindrical tube is orthogonal in the arrangement in space, such arrangement causes the lattice of defect (defect), and is considered to the pre-converted phenomenon (pre-transitionalphenomena) being entered cholesterol phase by liquid crystal phase.Therefore, indigo plant is classified as invalid phase (frustratedphases) mutually.The experimental research such as Bragg diffraction, Kossel diffraction chart, optical texture, crystal growth is utilized to find, BPII is simple cubic structure (SC:simplecubic) (Mol.Cryst.Liq.Cryst., Vol.465, pp.283-288,2007), BPI is body-centered cubic structure (BCC:body-centeredcubic).Be different from other liquid crystal phase, as nematic phase (nematic), smectic phase (smectic), even phase (isotropic), usual BPI, BPII can show the color graphics (J.A.C.S of many tabulars (platelettexture) under polarizing microscope, 2008,130,6326Kikuchiet.al.), this is because lattice period causes caused by Bragg reflection at visible wavelength range.
General liquid crystal has optics Contraphasic (opticallyanisotropic), but blue phase is but have the tropisms such as optics (opticallyisotropic).In other words, indigo plant has very low mutually or does not even have birefringence (Birefringence).
Lattice period due to blue phase is the function of visible wavelength, therefore can produce selectivity " Bragg reflection " (selectiveBraggreflection).This characteristic makes blue phase liquid crystal have to be applied in the light valve (fastlightmodulators) of rapid answer.But, no matter prediction in theory or observation experimentally, blue phase liquid crystal only appears at and has high-purity, height revolves in the molecular material of optical activity, and therefore blue phase liquid crystal exists only in very little temperature range (being less than the temperature range of 2 DEG C).Therefore, blue phase liquid crystal is only academicly coming into question usually, but does not come into one's own in practical application.
Nearly ten years, in order to make the display quality of display panels face to drive the display quality in cathode-ray tube (CRT), there is the blue attention being subject to again science and industrial community mutually of rapid answer characteristic.In order to the needs applied, blue phase liquid crystal must have broad temperature application range, and therefore different technical developments is suggested in succession.Such as, utilize the characteristic of stabilizing polymer (producing macromolecule reticulate texture) to produce the blue phase (Naturematerials, 2002,1,64) that can be present in broad temperature interval.In addition, in 2002, a small amount of molecule monomer and photoresist added in blue phase liquid crystal by the people such as Kikuchi, and in blue phase temperature range, irradiation produces the stable blue phase as gel structure, successfully produces the blue phase that temperature range is about 60 DEG C.
Although blue phase liquid crystal has the advantages such as tropism such as rapid answer time and optics, have the shortcoming that driving voltage is higher, its driving voltage is up to 55 volts.With regard to the angle of output, the high driving voltage of blue phase liquid crystal is one of problem needing solution badly.
