Nowadays we could get any information at any time and any place through various forms of displays such as smart phones, pads, laptops and TV sets. It would be interesting to see the displays are changing forms to fit into our life style and meet our interests or convenience. Transparent, rollable and foldable displays would be the typical example of the transition. To meet the speed of transition, many new technologies have been applied and no one would deny the OLED has been leading the change of display technology and contributing to the change of life style. Furthermore, the fact that the OLED could control its properties of light emitted from each pixel of display would be another change of display to the new application for healthcare.

The proposed circuit adopts the simultaneous emission driving method to extend the compensating time for precisely sensing the threshold voltage variation of driving TFTs. Moreover, the flicker phenomenon is ameliorated by adjusting the voltage level of ELVSS during the programming period. Simulation results show that the relative current error rates under various data voltages with VTH variation of driving TFT of ± 0.5 V are all less than 4.5%, demonstrating that the proposed pixel circuit can generate uniform driving currents flowing through OLEDs for high-quality images.","PeriodicalId":129222,"journal":{"name":"2019 26th International Workshop on Active-Matrix Flatpanel Displays and Devices (AM-FPD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127118835","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 micro-QE measurement is used for edge recombination analysis and reveals the recombination behavior of CIGS solar cells.

Herein, this study demonstrated the relevance about interface properties and microstructures of N,N′-ditridecyl-3,4,9,10-perylene tetracarboxylic diimide (PTCDI-C13H27) grown the PI layers of various solid content. Moreover, the microstructure of PTCDI-C13H27 affects the trap state in the channel, leading to the enhancement of electrical stability of the devices.
