Description
Technical field
The invention relates to a kind of display floater and manufacture method thereof, and in particular to a kind of display panels
And manufacture method.
Background technology
1888, cholesteric benzoate (cholesteric benzoate) was placed in by Friedrich Reinitzer
In polarizing microscope, it was observed that cholesteric benzoate can present with cholesteric phase (cholesteric) at homogeneous (isotropic)
Going out different colours (bluish violet and blueness), the color variation phenomenon homogeneously and between cholesteric phase exists only in the least temperature range
(about only having 1 DEG C of temperature range Celsius).1970, many scientists utilized analysis by measure, high-res differential scanning calorie meter
Etc. method, it was demonstrated that aforementioned phenomenon is a kind of new thermodynamically stable phase, and it is called blue phase (blue phase, BP).
General liquid crystal has optics Contraphasic (optically anisotropic), but blue phase is but to have optics
Etc. tropism (optically isotropic).In other words, blue phase has the lowest or does not even have birefringence
(birefringence).Due to the function that lattice period is visible wavelength of blue phase, therefore " Prague is anti-to produce selectivity
Penetrate " (selective bragg reflection).This characteristic makes blue phase liquid crystal have and applies the light valve at rapid answer
(fast light modulators).But, prediction the most in theory or observation experimentally, blue phase liquid crystal is only
Occur in and possess in the molecular material having high-purity, high optical activity, in therefore blue phase liquid crystal exists only in the least temperature range.
Therefore, blue phase liquid crystal the most only comes into question academicly, but does not come into one's own in reality application.
Nearly ten years, in order to make the display quality of display panels outmatch the display quality of cathode ray tube, have
The blue phase of rapid answer characteristic is paid attention to by academic and industrial circle again.For the needs on applying, blue phase liquid crystal must have
Having the temperature application range of broadness, the most different technology development is suggested in succession.Such as, the characteristic of stabilizing polymer is utilized
Blue phase that (produce macromolecule network structure) can be present in broad temperature interval with generation (Nature materials,
2002,1,64).Additionally, in 2002, Kikuchi et al. prepared the blue phase liquid of the stable blue phase with similar gels structure
Crystalline substance, successfully produces the blue phase that temperature range is about 60 DEG C Celsius.Although blue phase liquid crystal has rapid answer time and optics
Etc. advantages such as tropisms, but having the shortcoming that driving voltage is higher, its driving voltage is up to 55 volts.From the perspective of volume production, blue
The high driving voltage of phase liquid crystal is one of problem needing solution badly.
