Search of WIPO Database Unearths 104 OLED Patent Filings in Past Month

A lot of innovation is going on in OLED screen technology, our spot check on new patent filings finds. We searched around the world on pending patent applications published in the past month, using the World Intellectual Property Organization database in Geneva. As a general rule, publication follows 18 months after the first papers are filed anywhere in the world, so the WIPO results give the most up-to-date patent snapshots available. Our search unearthed 104 recent filings on OLED technology, including 26 from LG and 14 from Samsung, with 17 from Chinese company Shenzhen China Star Optoelectronics Technology, seven from BOE Technology Group, and two each from Corning and Nubia Technology. The patents variously cover flexible screens, double-sided screens and triple-layer pixel stacks, plus methods for higher-yield OLED manufacturing. Among the more noteworthy filings, Nubia Technology, of Shenzhen, filed for the idea of overlaying an e-ink screen with an OLED screen layer, with either or both of the two different display types then used for the best visual effect depending on the picture content (WO/2016/107308).
