The bistable scattering regime which is most appropriate for practical applications was found, and the total time of scattering switching on and switching off was less than 250μs at ± 80 V.

We prepared two cholesteric mixtures whose pitches were shifted one respect to the other in such a way that only the edges of band gaps of the cholesteric liquid crystals layers overlapped. Using these mixtures we have observed single mode lasing. Moreover the divergence of the laser beam spot is considerably lower than the one observed in dye doped cholesteric liquid crystal lasers.","PeriodicalId":353385,"journal":{"name":"International Symposium on Advanced Display Technologies","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129410098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dynamics of the domain wall motion in helix free FLC cell is considered. The domain wall motion velocity depends on the frequency of electric field change and on the polar coefficient of anchoring energy Wp. Increasing the frequency or the polar part ofthe anchoring energy (when the frequency is constant) gives rise to decrease of electrooptic response time 1/τ0.1-0.9 by a factor 2-3 times. Due to this the electrooptical response time can be as small as 100 μs when the electric field is about 4V/μm. These parameters are most suitable to be used in an active matrix display (or micro-display) with the high resolution.","PeriodicalId":353385,"journal":{"name":"International Symposium on Advanced Display Technologies","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133687911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electro-optical researches have shown that the reorientation of MBBA in composites does not occur in a wide interval of frequencies and voltage irrespective of the sizes of pores. The similar researches have shown that X-16 in composites also is not exposed to action of electric field.
