13.1 - Invited Paper: New Frontier in Display Technology: OPD Sensor in OLEDs for Healthcare Application (2:00 PM - 2:20 PM)
  • Sunghan Kim, Seokgyu Yoon, Jinsoo Jung, Min-Soo Choi, Chul Kim
    Samsung Display Co., Ltd. Yongin South Korea


  • Red light can be used for organic photodetectors (OPDs) in an all-in-one sensor display. Red pixels are used as the light source and an OPD capable of effective detection of  625 nm light is demonstrated with an EQE of 25%. These results show that OLED panels can be used for fingerprint recognition and as a health care platform.

13.2 - Organic Light-Emitting Diode Display Constitutes Side-by-Side OLED and Organic Photodiode Pixels Integrated in the Same Plane by Adopting Metal Mask-Less Lithography (MML) Technology (2:20 PM - 2:40 PM)
  • Kazuya Sugimoto, Ryo Hatsumi, Taisuke Kamada, Daisuke Kubota, Kenichi Okazaki, Sachiko Yamagata, Shunpei Yamazaki
    Semiconductor Energy Laboratory Co., Ltd. Kanagawa Japan

  • Yasutaka Nakazawa, Satoru Idojiri
    Semiconductor Energy Laboratory Co., Ltd. Tochigi Japan


  • This study presents the fabrication of a 513ppi organic light-emitting diode (OLED) display featuring an integrated organic photodiode (OPD) within each pixel, eliminating the need for a fine metal mask. The fabrication process involves photolithography for the side-by-side patterning of OLED and OPD subpixels, leading to a four-subpixel configuration.

13.3 - Full-Screen Fingerprint Display with Embedded Organic Photo-Detectors (2:40 PM - 3:00 PM)
  • Kwang Soo Bae, Gun Hee Kim, Hyang A Park, Jungwoo Park, Taekyung Ahn, Yongjo Kim
    Samsung Display Yongin South Korea


  • This paper introduces a fully integrated in-cell fingerprint sensor display. An organic photo-detector (OPD) is embedded into a flexible OLED display plane to enable fingerprint sensing across the entire display active area while maintaining high display quality. No increased thickness or process cost is expected due to the efficient integration method.
