The flat frequency dependence of the Vth can be realized by making the resistivities of the LC and aligning layer sufficiently high. By using this method, the crosstalk caused by the frequency dependence of the Vth can be eliminated, even when the polarities of the pixel driving waveform are inverted in much longer cycles. Crosstalk-free and low-power-consumption LCDs can be realized by combining the driving method of Y. Kaneko et al.

The comparison shows that under point source illumination parasitic effects determine the resulting contrast distribution rather than intrinsic properties of the LC-layer and that the basic features of the transmissive mode (e.g. main viewing direction) cannot be reproduced adequately. In order to obtain reasonable and meaningful results, specular and diffuse components of the light reflected by LCDs must be separated during the measurement of the angular contrast distribution. This can be conveniently achieved with the diffusing hemisphere, a device that also allows for the measurement of the diffuse/normal reflectance factor, a suitable figure of brightness for reflective LCDs.<<ETX>>","PeriodicalId":399708,"journal":{"name":"Conference Record of the 1991 International Display Research Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129052206","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}

However, the DC offset voltage differences between ON-state and OFF-state are changed according to bias ratio. Therefore, the image-sticking can be reduced to less than 1%, both by bias ratio optimization and by its compensation according to temperature changes.<<ETX>>","PeriodicalId":399708,"journal":{"name":"Conference Record of the 1991 International Display Research Conference","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120069128","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}

In this way, the feasibility of full-color MFDs has been demonstrated.

A polymer gel can be used to stabilize the optical states of a cholesteric liquid crystal to create a bistable color display. This system has a high potential for multiplexed flat panel displays without the use of an active matrix substrate. Such a display can also be used for long-term information storage and optical signal processing.<<ETX>>","PeriodicalId":399708,"journal":{"name":"Conference Record of the 1991 International Display Research Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116212741","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}

Due to the reduced magnification factor and space charge effect, plus a strong prefocusing BFR, this gun had a 35% improved low-current (100- mu A) spot and 25% improved high-current (5-mA) spot compared to the conventional Hi-UPF projection gun. This gun uses conventional oxide cathode and conventional electron gun manufacturing technology. This will reduce the production cost and minimize many of the long-term performance uncertainties of a newly developed gun. Although this gun was developed as a monochrome projection gun, the authors believe that through a minor reoptimization this design can be used for the color inline gun system.<<ETX>>","PeriodicalId":399708,"journal":{"name":"Conference Record of the 1991 International Display Research Conference","volume":"250 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1991-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126772966","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}
