However, there are some shortcomings in the realization of white-light OLED devices, such as insufficient luminous performance, difficult process control, and easy color drift. To solve these problems, the optimized ratios of primary colors(red, green, and blue) of organic OLED devices were preliminarily obtained through the realization of white light and calculation of the color coordinate. An experimental white-light OLED device was prepared with a color coordinate of (0.31, 0.35). Further, theoretical calculations and experimental optimizations were carried out to reduce the red-light doping concentration and increase the green-light doping ratio to realize standard white-light (0.33, 0.33) OLED devices.","PeriodicalId":64126,"journal":{"name":"红外技术","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43889189","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 method improves the reliability of automatic focusing processes. By introducing the sensitivity of image sharpness evaluation function as feedback into the climbing process, the convergence speed of the climbing algorithm can be optimized.

According to the YOLO v3 algorithm, the basic network architecture was optimized by including a convolution module and adjusting some hyper-parameters to realize rapid detection and identification of abnormal heating points in high-voltage switchgears. Simultaneously, a dataset for abnormal heating points of infrared images in high-voltage switchgears was established, and appropriate weights were obtained through training. The experimental results indicated that the detection method had a fast recognition speed, high accuracy, and strong generalization ability. The test accuracy reached 91.83%, indicating that the method can be initially applied to the detection of abnormal heating-point targets in high-voltage switchgears.","PeriodicalId":64126,"journal":{"name":"红外技术","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45036639","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}
