Meanwhile, PV systems installed in the large open-area have a possibility to be exposed to lightning strike, however there were few studies about effects of lightning strike on crystalline Si PV modules. In this study, we focused on effect of lightning impulse voltage on PID in crystalline Si PV modules. Lightning strike was simulated by a high impulse voltage generator. To reveal the effects of impulse voltage on PID in the modules, several investigations were used such as dark current-voltage measurement, electroluminescence image, and leakage current measurement. As a result, the lightning impulse voltages (−20 kV, −40kV, and +20 kV) completely accelerated the PID in the crystalline Si PV modules.","PeriodicalId":221271,"journal":{"name":"2018 25th International Workshop on Active-Matrix Flatpanel Displays and Devices (AM-FPD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126863059","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}

Especially in automotive applications, rough antiglare (AG) surface treatments are applied to the top surface. However, a rough surface on top of a brilliant display has a direct impact on its image quality. Carefully designing the AG surface allows a compromise between reflection suppression and image quality. One of the undesired effects is the so-called “visual sparkling”, where the displayed image appears to show an uneven luminance distribution especially in areas where solid colors are shown. This effect itself is quite subjective for that it is necessary to quantify it in a reproducible way. In this work, we present a simple yet effective method for characterization of the sparkle effect based on the evaluation of image uniformity with help of grey-value histogram extraction and fitting with a simple normal distribution.","PeriodicalId":221271,"journal":{"name":"2018 25th International Workshop on Active-Matrix Flatpanel Displays and Devices (AM-FPD)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127429536","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}
