Furthermore the light is directly introduced to the panel glass substrates from the edge of the substrates (not from back surface). At surface of the substrates, the light takes a total reflection and propagates through the substrate. On the other hand, when a voltage higher than a threshold voltage (Vth) is applied to liquid crystal (LC) layer, the light is scattered towards the viewers. This newly developed display has high transmittance (80 %), wide color gamut and fast response time.","PeriodicalId":376983,"journal":{"name":"2017 24th International Workshop on Active-Matrix Flatpanel Displays and Devices (AM-FPD)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132413172","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}
