Light illumination can change many electrical properties in oxide TFTs such as mobility and threshold voltage (Vth). In many researches, Oxygen vacancy is suspected as a main cause of the changes by light illumination. Recently, the back channel formation by field-induced macroscopic barrier model is reported under light illumination. This is also related to Oxygen vacancy. In this letter, we investigate the gradual changes in DC and CV characteristics depending on the dual-channel thicknesses. For this purpose, we use the aluminum-doped indium zinc tin oxide (AIZTO)/indium zinc oxide (IZO) dual-channel TFTs. The main goal of this paper is to find the main cause of the changes by light illumination in various dual-channel thicknesses.","PeriodicalId":422453,"journal":{"name":"2016 23rd International Workshop on Active-Matrix Flatpanel Displays and Devices (AM-FPD)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134263509","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 proposed pixel circuit consists of five thin film transistors (TFTs) and one capacitor. Due to the AC bias, the OLED is reverse biased during the non-emission period, which not only prevents the OLED from light emitting during the programming period to ensure a high contrast ratio displays; but also suppresses the OLED degradation and thus extends the lifetime of the AMOLED displays. It is verified that the proposed circuit can compensate for the threshold voltage variations of the driving TFT and the OLED.","PeriodicalId":422453,"journal":{"name":"2016 23rd International Workshop on Active-Matrix Flatpanel Displays and Devices (AM-FPD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130473001","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}

To quantize folding conditions, AFTS for folding function is utilized to control radii of curvature of the flexible substrates, folding times, and velocities. Additionally, AFTS measures the electrical characteristics of flexible substrates during folding test. As a result, the new technique successfully measures electrical characteristics of flexible polydimethylsiloxane (PDMS)/gold electrodes for analysis during the 0/cm to 0.5/cm curvature folding cycles. Inspection results of folding characteristics depicted on flexible displays help a designer or maker of flexible displays design useful and comfortable flexible electronic products.","PeriodicalId":422453,"journal":{"name":"2016 23rd International Workshop on Active-Matrix Flatpanel Displays and Devices (AM-FPD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126639345","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}
