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 (blue phase liquid crystal display panel) and driving method thereof.
Background technology
1888 Christian eras; Friedrich Reinitzer places polarizing microscope with cholesterol type benzoate (Cholesteric benzoate); Observe the cholesterol type benzoate even phase (Isotropic) and cholesterol mutually (Cholesteric) can demonstrate different colours (bluish violet and blueness), even and the cholesterol change color phenomenon between mutually exists only in very little temperature range (having only 1 ℃ of temperature range approximately).In 1970 Christian eras, many scientists utilize methods 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 BP I, BP II, BP III mutually, and the temperature that BP III exists be three the highest in mutually, the BP III that in document, mentions is " fog phase ".Compared to the cube structure (cubic) of BP I and BP II, BP III is unformed (amorphous).Under polarizing microscope, observe, BP III does not normally have the fuzzy image of any structure, therefore is difficult to observe under the polarizing microscope.
And the structure of BP I, BP II has been proved, and the elementary cell that constitutes BP I, BP II is " two reverse cylindric " (DTC:double twist cylinder), and such arrangement mode has minimum free energy.In addition, two to reverse the arrangement of cylindrical tube in the space be orthogonal, and such arrangement causes the lattice of defective (defect), and be considered to got into by liquid crystal phase the pre-converted phenomenon (pre-transitional phenomena) of cholesterol phase.Therefore, the blue invalid phase (frustrated phases) that classified as.Utilize experimental discovering such as Bragg diffraction, Kossel diffraction chart, optical texture, crystal growth; BP II is simple cubic structure (SC:simple cubic) (Mol.Cryst.Liq.Cryst.; Vol.465; Pp.283-288,2007), BP I is body-centered cubic structure (BCC:body-centered cubic).Be different from other liquid crystal phase; Like nematic phase (nematic), smectic phase (smectic), even phase (isotropic); Usually BP I, BP II can show color graphics (J.A.C.S, 2008,130 of many tabular (platelet texture) under polarizing microscope; 6326 Kikuchi et.al.), this is because lattice period causes due to the Bragg reflection at visible wavelength range.
General liquid crystal has optics out-phase property (optically anisotropic), but blue but be to have tropism (optically isotropic) such as optics mutually.In other words, indigo plant has very low mutually or does not even have birefringence property (Birefringence).
Because the lattice period of blue phase is the function of visible wavelength, so can produce selectivity " Bragg reflection " (selective Bragg reflection).This specific character makes blue phase liquid crystal have to be applied in the light valve (fast light modulators) of rapid answer.But, no matter in theory still experimentally observation of prediction, blue phase liquid crystal only appear at possess high-purity is arranged, in the molecular material that height revolves optical activity, so blue phase liquid crystal exists only in the very little temperature range (less than 2 ℃ temperature range).Therefore, blue phase liquid crystal is only academicly coming into question usually, but in practical application, does not come into one's own.
Over past ten years,, has the blue attention that receives science and industrial community mutually again of rapid answer characteristic for the display quality that makes display panels faces the display quality of driving in cathode-ray tube (CRT).For the needs on using, blue phase liquid crystal must possess has broad temperature application range, so the different techniques development is suggested in succession.For example, utilize the characteristic (producing the macromolecule reticulate texture) of stabilizing polymer can be present in the blue phase (Nature materials, 2002,1,64) in the broad temperature range to produce.In addition, in 2002, people such as Kikuchi added a spot of molecule monomer and photoresist in the blue phase liquid crystal, and irradiation produces as the stable blue phase of gel structure in blue phase temperature range, successful produced the blue phase that temperature range is about 60 ℃.
Though blue phase liquid crystal has advantages such as tropism such as rapid answer time and optics, and the higher shortcoming of driving voltage is arranged, 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 of needing badly solution.
